    BACKGROUND AND AIMS: The diagnostic performance of the Fibrosis-4 (FIB-4) index and nonalcoholic fatty liver disease (NAFLD) fibrosis score (NFS) is poor in patients with type 2 diabetes mellitus (T2DM). We determined the usefulness of the enhanced liver fibrosis (ELF) test in patients with T2DM. METHODS: A total of 1,228 patients with biopsy-proven NAFLD were enrolled. The diagnostic performance of the ELF test for predicting advanced fibrosis in participants with or without T2DM was evaluated in comparison with the FIB-4 index and NFS. RESULTS: Overall, the area under the curve of the ELF test for predicting advanced fibrosis was greater (0.828) than that of the FIB-4 index (0.727) and NFS (0.733). The diagnostic performance of the ELF test (area under the curve 0.820) was also superior to that of the FIB-4 index (0.698) and NFS (0.700) in patients with T2DM. With the low cutoff values for each non-invasive test, the ELF test provided an acceptable false-negative rate (cutoff value 9.8, 6.7%) in this population, unlike the FIB-4 index (1.30, 14.5%) and NFS (-1.455, 12.4%). After propensity score matching to avoid selection bias including age, sex, body mass index, and the prevalence of advanced fibrosis, the ELF test with a low cutoff value showed a high sensitivity (≥91.4%) and a high negative predictive value (≥96.8%), irrespective of the presence or absence of T2DM. CONCLUSION: The high diagnostic performance of the ELF test for predicting advanced fibrosis in individuals with or without T2DM could address an unmet medical need for accurate assessment of liver fibrosis in patients with diabetes and NAFLD.

    BACKGROUND/AIMS: Metabolic dysfunction-associated steatotic liver disease (MASLD) was recently proposed as an alternative disease concept to nonalcoholic fatty liver disease (NAFLD). We aimed to investigate the prognosis in patients with biopsy-confirmed MASLD using data from a multicenter study. METHODS: This is a sub-analysis of the CLIONE (Clinical Outcome Nonalcoholic Fatty Liver Disease) study, included 1,398 patients with NAFLD. Liver biopsy specimens were pathologically diagnosed, and histologically scored using the NASH Clinical Research Network system. Patients who met at least one cardiometabolic criterion were diagnosed with MASLD. RESULTS: Approximately 99% of cases (n=1,381) were classified as MASLD. Patients without any cardiometabolic risk (n=17) had a significantly lower BMI than patients with MASLD (28.0 vs. 20.9 kg/m2, P<0.001), significantly lower levels of inflammation, ballooning, NAFLD activity score, and fibrosis stage in liver histology. These 17 patients had a median follow-up of 5.9 years, equivalent to 115 person-years, with no deaths, liver-related events, cardiovascular events, or extrahepatic cancers. The results showed that the prognosis for pure MASLD was similar with the original CLIONE cohort, with 47 deaths, and 1 patient underwent orthotopic liver transplantation. The leading cause of death was extrahepatic cancer (n =10). The leading causes of liver-related death were liver failure (n =9), hepatocellular carcinoma (n =8), and cholangiocellular carcinoma (n =4). CONCLUSIONS: Approximately 99% of NAFLD cases corresponded to MASLD. NAFLD only group, which is not included in MASLD, had relatively mild histopathologic severity and a favorable prognosis. Consequently, the prognosis of MASLD was similar to that of NAFLD.

    AIM: The prevalence of nonalcoholic fatty liver disease (NAFLD) is increasing worldwide. The aim of this study was to determine the recent prevalence and clinical characteristics of NAFLD in Japan. METHODS: This study initially included 410,061 retrospectively enrolled adults from the medical health checkup registry for metabolic syndrome, chronic kidney disease, and fatty liver in Japan (MIRACLE-J; UMIN-CTR no. UMIN000049419), who were evaluated between 2014 and 2018 at 13 health centers in Japan. Subjects consuming > 20 g of alcohol/day or with chronic liver disease were excluded. Fatty liver was diagnosed by ultrasonography. The probability of NAFLD with advanced fibrosis was estimated based on the fibrosis-4 index (FIB-4) and NAFLD fibrosis score (NFS). RESULTS: A total of 71,254 subjects were included in the final analysis. The overall prevalence of NAFLD was 25.8%. There was a significant, 2-fold difference in NAFLD prevalence between males (37.4%) and females (18.1%). NAFLD prevalence increased linearly with body mass index, triglycerides, and low-density lipoprotein cholesterol regardless of threshold values, even in the absence of obesity. Among patients with NAFLD, 14% had diabetes mellitus, 31% had hypertension, and 48% had dyslipidemia. The estimated prevalence of NAFLD with advanced fibrosis was 1.7% and 1.0% according to FIB-4 and NFS, respectively. CONCLUSIONS: The prevalence of NAFLD was approximately one-quarter of the general population in Japan. There was a linear relationship between NAFLD prevalence and various metabolic parameters, even in nonobese subjects. The prevalence of NAFLD with advanced fibrosis was estimated to be 1% to 2%.

    AIM: The noninvasive tests (NITs) Agile 3+ and Agile 4 effectively identify patients with nonalcoholic fatty liver disease (NAFLD) complicated with advanced fibrosis (F3-4) and cirrhosis (F4), respectively. Little information is available on associations between Agile scores and intra-/extrahepatic events. The aim of this study was to determine the predictive performance of Agile scores for intra-/extrahepatic events in Asian patients with biopsy-proven NAFLD. METHODS: We undertook a retrospective multicenter cohort study to investigate associations between intra-/extrahepatic events and two Agile scores, Agile 3+ and Agile 4. The scores were obtained by combining clinical parameters and liver stiffness measurement using transient elastography. RESULTS: Among 403 enrolled patients, 11 had liver-related events (LREs), including seven with hepatocellular carcinoma (HCC). The incidence of LREs and HCC showed a stepwise increase in the advanced fibrosis group (F3-4), Agile 3+ rule-in (F3-4, highly suspected), and Agile 4 rule-in (F4, highly suspected) groups, compared to their counterparts. Hazard ratios for LREs in the advanced fibrosis group, Agile 3+ rule-in, and Agile 4 rule-in groups were 4.05 (p = 0.03), 23.5 (p = 0.003), and 45.5 (p < 0.001), respectively. The predictive performance results for Agile 3+ and Agile 4 were 0.780 and 0.866, respectively, which were higher than for fibrosis (0.595). Unlike for LREs, Agile scores failed to identify patients with extrahepatic events, including cardiovascular events and extrahepatic cancer. CONCLUSIONS: Agile 3+ and Agile 4 scores are excellent NITs for predicting LREs in patients with NAFLD, possibly without histological assessment.

    BACKGROUND AND AIMS: Both fibrosis status and body weight are important for assessing prognosis in nonalcoholic fatty liver disease (NAFLD). The aim of this study was to identify population clusters for specific clinical outcomes based on fibrosis-4 (FIB-4) index and body mass index (BMI) using an unsupervised machine learning method. METHODS: We conducted a multicenter study of 1335 biopsy-proven NAFLD patients from Japan. Using the Gaussian mixture model to divide the cohort into clusters based on FIB-4 index and BMI, we investigated prognosis for these clusters. RESULTS: The cohort consisted of 223 cases (16.0%) with advanced fibrosis (F3-4) as assessed from liver biopsy. Median values of BMI and FIB-4 index were 27.3 kg/m2 and 1.67. The patients were divided into four clusters by Bayesian information criterion, and all-cause mortality was highest in cluster d, followed by cluster b (P = 0.001). Regarding the characteristics of each cluster, clusters d and b presented a high FIB-4 index (median 5.23 and 2.23), cluster a presented the lowest FIB-4 index (median 0.78), and cluster c was associated with moderate FIB-4 level (median 1.30) and highest BMI (median 34.3 kg/m2 ). Clusters a and c had lower mortality rates than clusters b and d. However, all-cause of death in clusters a and c was unrelated to liver disease. CONCLUSIONS: Our clustering approach found that the FIB-4 index is an important predictor of mortality in NAFLD patients regardless of BMI. Additionally, non-liver-related diseases were identified as the causes of death in NAFLD patients with low FIB-4 index.

    OBJECTIVE: Liver stiffness measurements (LSMs) and controlled attenuation parameters (CAPs) obtained using vibration-controlled transient elastography (VCTE) are recognized non-invasive methods of assessing liver histology. The usefulness of CAP for predicting liver-related events (LREs: hepatocellular carcinoma, decompensation, bleeding varices) is not well understood worldwide. Our aim was to re-evaluate the cutoff values of LSM/CAP in Japan and to examine whether LSM/CAP can predict LRE. METHODS: Japanese NAFLD patients (n = 403) who underwent both liver biopsy and VCTE were enrolled. We determined optimal cutoff values of LSM/CAP diagnoses for fibrosis stage and steatosis grade and investigated their clinical outcome based on LSM/CAP values. RESULTS: The LSM cutoff values for F1 to F4 are 7.1, 7.9, 10.0 and 20.2 kPa, and the CAP cutoff values for S1 to S3 are 230, 282 and 320 dB/m. During a median follow-up of 2.7 y (range: 0.0-12.5 y), 11 patients developed LREs. The incidence of LREs in the LSM Hi (≥8.7) group was significantly higher than that in the LSM Lo (<8.7) group (p = 0.003), and the incidence in the CAP Lo (<295) group was higher than that in CAP Hi (≥295) group (p = 0.018). Considering LSM and CAP together, the risk of LRE was higher in the LSM Hi CAP Lo group than in the LSM Hi CAP Hi group (p = 0.03). CONCLUSION: We set LSM/CAP cutoff values to diagnose liver fibrosis and steatosis in Japan. Our study determined that NAFLD patients with high LSM and low CAP values are at high risk for LREs.

    Atezolizumab plus bevacizumab (Atezo + Bev) is the first immunotherapy for hepatocellular carcinoma (HCC), and in the current guidelines, it is positioned as the first-line chemotherapy for unresectable cases. Herein, we report a case of HCC with pseudoprogression followed by a complete response to Atezo + Bev. A 56 year-old man was diagnosed with intermediate-stage HCC, as defined by the Barcelona Clinic Liver Cancer system stage B. Computed tomography (CT) revealed multiple lesions in the liver without any extrahepatic lesions. First, he was treated with transcatheter arterial chemoembolization (TACE); however, multiple residual lesions were observed on CT scan 2 months after TACE. Therefore, treatment with Atezo + Bev was initiated 4 months after TACE. After the third administration of Atezo + Bev, a CT scan showed progressive disease in intrahepatic lesions, along with increased serum levels of tumor markers. Although TACE was planned again, Atezo + Bev was continued while the patient was waiting for hospitalization. After the fifth administration of Atezo + Bev, serum levels of tumor markers decreased to the normal range. Magnetic resonance imaging showed prominently reduced tumor size. Therefore, Atezo + Bev was continued, and after the eighth administration, the CT scan showed the disappearance of all the liver lesions, indicating a complete response. In immunotherapy, the therapeutic response can sometimes be obtained in an atypical pattern due to either an increase in tumor burden or the appearance of new lesions, called "pseudoprogression," which is rare in HCC.

    BACKGROUND & AIMS: Noninvasive tests (NITs) have prognostic potential, but whether NITs are comparable with liver biopsy is unclear. This study aimed to examine the prognostic accuracy of NITs for liver-related mortality (LRM) and events (LREs) in patients with biopsy-proven NAFLD. METHODS: We investigated 1,313 patients with NAFLD. Patients were assigned to low-, indeterminate-, and high-risk groups using conventional cutoff values of each FIB-4 and NAFLD fibrosis score (NFS), and to stage 0-2 and stage 3-4 groups using the fibrosis stage. Survival and Cox regression analyses of the prognostic potential of NITs for LRM/LREs were conducted. RESULTS: During a median follow-up of 4.5 years, regarding to FIB-4, the incidence rate (/1000 person-years) in the low-risk was zero for LRM, and 0.5 for LREs. In contrast, the rate in stage 0-2 was 1.3 for LRM, 2.8 for LRE. The adjusted hazard ratios (aHRs) for LREs in the high-risk compared with the low-risk were 32.85 (p<0.01). The aHRs in stage 3-4 compared with stage 0-2 were 2.68 (p=0.02) for LREs, and 2.26 (p=0.582) for LRM. In the same fibrosis stage, the incidence of LRM/LREs was more frequent with a higher risk stratification. The same trend was observed for NFS. CONCLUSIONS: NITs accurately predict LRM and LREs as well as a liver biopsy in Japanese patients with NAFLD. Patients in the low-risk may not require close follow-up for at least 5 years. The simple NITs could be an acceptable alternative method to performing a liver biopsy for the prognosis of NAFLD.

    アテゾリズマブおよびベバシズマブ併用療法(Atezo+Bev)は、初めて認可された肝細胞癌(HCC)に対する免疫療法で、現行のガイドラインでは、切除不能例に対する一次療法と位置づけられている。Atezo+Bevにより、偽進行後に完全寛解に至った肝細胞癌の一例を報告した。症例は56歳男性で、中程度病期(バルセロナクリニック肝癌システム病期B)のHCCで、CT検査により肝内に多発病変が認められ、肝外病変は認められなかった。初回治療として、経カテーテル的動脈化学塞栓療法1(TACE)を施行したが、TACE施行2ヵ月後のCT検査で、多発遺残病変が認められた。TACEの4ヵ月後にAtezo+Bevを導入した。3回投与後、CTで肝内病変の進展が認められ、同時に血清腫瘍マーカーが上昇した。TACEを再度施行する予定としたが、入院待機中にはAtezo+Bevを継続した。Atezo+Bevの5回投与後、血清腫瘍マーカー値は正常化し、MRI検査で腫瘍径の著明な縮小が確認された。以上の経過から、Atezo+Bevを継続し、第8回投与後にはCT検査で全ての肝内病変の消失が確認され、完全寛解と判定した。免疫療法においては、偽進行と呼ばれるような、腫瘍病巣の増加や新規病変の発生により治療効果が非定型的に認められることがあるが、HCCでは稀である。

    AIM: Agile 3+ and Agile 4 scores, based on liver stiffness measurement (LSM) by transient elastography and clinical parameters, were recently reported to be effective in identifying advanced fibrosis and cirrhosis in nonalcoholic fatty liver disease (NAFLD). This study aimed to validate the utility of these scores in Japanese patients with NAFLD. METHODS: Six hundred forty-one patients with biopsy-proven NAFLD were analyzed. The severity of liver fibrosis was pathologically evaluated by one expert pathologist. LSM, age, sex, diabetes status, platelet count, and aspartate aminotransferase and alanine aminotransferase levels were used to calculate Agile 3+ scores, and the parameters above excluding age were used for Agile 4 scores. The diagnostic performance of the two scores was evaluated using receiver operating characteristic (ROC) curve analysis. Sensitivity, specificity, and predictive values of the original low cut-off (for rule-out) value and high cut-off (for rule-in) value were tested. RESULTS: For diagnosis of fibrosis stage ≥ 3, the area under the ROC (AUROC) was 0.886, and the sensitivity of the low cut-off value and the specificity of the high cut-off value were 95.3% and 73.4%, respectively. For diagnosis of fibrosis stage 4, AUROC, the sensitivity of the low cut-off value, and the specificity of the high cut-off value were 0.930, 100% and 86.5%, respectively. Both scores had higher diagnostic performance than the FIB-4 index and the enhanced liver fibrosis score. CONCLUSIONS: Agile 3+ and Agile 4 are reliable noninvasive tests to identify advanced fibrosis and cirrhosis in Japanese NAFLD patients with adequate diagnostic performance.

    A direct-acting antiviral (DAA)-induced sustained virological response (SVR) reduces the risk of mortality. However, the risk factors associated with liver-related and non-liver-related mortality following a SVR after DAA treatment are unclear. We assessed the incidence and risk factors of liver-related and non-liver-related mortality in 1180 patients who achieved a SVR after DAA treatment. During the follow-up period after DAA treatment (median duration, 1099 [range: 84-2345] days), 53 (4.5%) patients died: 15 due to liver-related mortality, 25 due to non-liver-related mortality and 13 due to unknown causes. The all-cause, liver-related and non-liver-related mortality rates were 14.9, 4.2 and 7.0/1000 person-years, respectively. In a multivariate analysis, the development of hepatocellular carcinoma (HCC) after DAA treatment (p = .009; hazard ratio [HR], 31.484), an estimated glomerular filtration rate (eGFR) at baseline ≤61.68 ml/min/1.73 m2 (p = .015; HR, 6.607), and an α-fetoprotein level post-treatment ≥7.6 ng/ml (p = .041; HR, 18.490) were significantly associated with liver-related mortality. Furthermore, eGFR ≤67.94 ml/min/1.73 m2 at baseline (p = .012; HR, 3.407) and albumin-bilirubin (ALBI) grade ≥ 2 at SVR (p = .024; HR, 3.449) were significantly associated with non-liver-related mortality. Early diagnosis and therapeutic interventions for HCC development after DAA treatment are important to reduce liver-related mortality. The ALBI grade, which reflects the hepatic functional reserve, is a useful predictor of non-liver-related mortality after a SVR induced by DAA treatment. Furthermore, the renal dysfunction caused by metabolic syndrome may affect prognosis even after eliminating hepatitis C virus.

    AIM: Impacts of platelet counts at the time of liver biopsy on hepatocellular carcinoma (HCC) development in patients with nonalcoholic fatty liver disease (NAFLD) remain unknown. The aim of this study was to investigate the prognostic value of platelet counts in patients with biopsy-confirmed NAFLD using data from a multicenter study. METHODS: 1398 patients were included in this sub-analysis of the CLIONE (Clinical Outcome Nonalcoholic Fatty Liver Disease) in Asia study. Liver biopsy specimens were pathologically diagnosed, and histologically scored using the NASH Clinical Research Network system. Demographic, clinical, laboratory, and pathological data were collected. RESULTS: During a median follow-up period of 4.6 years (range, 0.3-21.6 years), which corresponds to 8,874 person-years, 37 patients developed HCC. Using a cutoff baseline platelet count of 192×109 /L, the lower platelet group had a higher HCC rate than the higher platelet group (6.7% vs. 0.4%; P<0.001). This cutoff value significantly stratified the event-free rate for HCC. Lower platelet counts were associated with an increased risk of HCC development. Relative to patients with platelet counts of 192×109 /L, patients with platelet counts of 100×109 /L had an unadjusted hazard ratio (HR) for HCC development of 7.37 (95% confidence interval [CI], 3.81-14.2) and an adjusted HR of 11.2 (95% CI, 3.81-32.7; P<0.001), adjusting for age, sex, and advanced fibrosis (Stage 3-4). CONCLUSIONS: Baseline platelet counts less than 192×109 /L and lower are associated with a higher risk of developing HCC in patients with biopsy-confirmed NAFLD and require active surveillance.

    BACKGROUND: It is unclear whether hepatocyte function and/or portal hypertension improves if a sustained virologic response (SVR) is achieved with direct-acting antivirals in patients with decompensated hepatitis C-related cirrhosis. METHODS: We examined the safety and efficacy of a 12-week course of sofosbuvir/velpatasvir (SOF/VEL) in 20 patients with decompensated hepatitis C-related cirrhosis. We also investigated changes in the hepatocyte receptor index (LHL15) and blood clearance index (HH15) by Tc-99 m-galactosyl human serum albumin scintigraphy, liver stiffness measurement (LSM) by transient elastography, and hepatic venous pressure gradient (HVPG) in patients who achieved an SVR at 24 weeks after treatment (SVR24). RESULTS: One patient discontinued treatment because of rectal variceal hemorrhage, and 19 patients completed treatment. SVR24 was achieved in 17 patients (89%). Median LHL15 increased from 0.72 pre-treatment to 0.82 after SVR24 (p = 0.012), and median HH15 decreased from 0.82 pre-treatment to 0.76 after SVR24 (p = 0.010). The percentage of patients with LSM ≥ 20 kPa was 90% before treatment and remained at 90% after SVR24. However, the percentage with severe portal hypertension (defined as HVPG ≥ 12 mmHg) decreased from 92% pre-treatment to 58% after SVR24 (p = 0.046). Patients with a decreased HVPG from pre-treatment to after SVR24 had a smaller pre-treatment spleen volume than those with an increased HVPG (median, 252 vs. 537 mL, p = 0.028). CONCLUSION: Achieving SVR24 with SOF/VEL treatment in patients with decompensated hepatitis C-related cirrhosis can be expected to improve hepatocyte function and portal hypertension on short-term follow-up.

    <jats:p>It is not fully clear as to which dietary patterns are associated with the pathogenesis of nonalcoholic fatty liver disease (NAFLD) in Asia. We conducted a cross-sectional study of 136 consecutively recruited patients with NAFLD (49% female, median age 60 years). Severity of liver fibrosis was assessed using the Agile 3+ score, a recently proposed system based on vibration-controlled transient elastography. Dietary status was assessed using the 12-component modified Japanese diet pattern index (mJDI12). Skeletal muscle mass was assessed by bioelectrical impedance. Factors associated with intermediate–high-risk Agile 3+ scores and skeletal muscle mass (75th percentile or higher) were analyzed by multivariable logistic regression. After adjustment for confounders, such as age and sex, the mJDI12 (OR: 0.77; 95% CI: 0.61, 0.99) and skeletal muscle mass (75th percentile or higher) (OR: 0.23; 95% CI: 0.07, 0.77) were significantly associated with intermediate–high-risk Agile 3+ scores. Soybeans and soybean foods were significantly associated with skeletal muscle mass (75th percentile or higher) (OR: 1.02; 95% CI: 1.00, 1.04). In conclusion, the Japanese diet pattern was associated with the severity of liver fibrosis in Japanese patients with NAFLD. Skeletal muscle mass was also associated with the severity of liver fibrosis, and intake of soybeans and soybean foods.</jats:p>

    BACKGROUND & AIMS: There are no detailed reports of clinical outcomes in Asian patients with nonalcoholic fatty liver disease (NAFLD) who undergo liver biopsy. We aimed to investigate the clinical outcomes of a large cohort of Asian patients with biopsy-proven NAFLD and evaluate the specific effects of nonalcoholic steatohepatitis and fibrosis stage. METHODS: This multicenter registry-based retrospective cohort study, called the CLIONE (Clinical Outcome Nonalcoholic Fatty Liver Disease) in Asia, included 1398 patients. RESULTS: The median follow-up period was 4.6 years (range, 0.3-21.6 years), representing a total of 8874 person-years of follow-up. During that time, 47 patients died, and 1 patient underwent orthotopic liver transplantation. The leading cause of death was nonhepatic cancer (n = 10). The leading causes of liver-related death were liver failure (n = 9), hepatocellular carcinoma (HCC) (n = 8), and cholangiocellular carcinoma (n = 4). During follow-up, 37 patients developed HCC, 31 developed cardiovascular disease, and 68 developed nonhepatic cancer (mainly breast, stomach, and colon/rectum). Among our cohort of patients with NAFLD, liver-specific mortality was 2.34/1000 person-years (95% confidence interval [CI], 1.52-3.58), overall mortality was 5.34/1000 person-years (95% CI, 4.02-7.08), and HCC incidence was 4.17/1000 person-years (95% CI, 3.02-5.75). Liver fibrosis was independently associated with liver-related events but not overall mortality. CONCLUSIONS: Liver-related mortality was the leading cause of mortality in Asian patients with biopsy-confirmed NAFLD. Although fibrosis stage was independently associated with liver-related events, it was not associated with overall mortality after adjusting for confounders, such as histologic features of steatohepatitis.

    Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease. Nonalcoholic steatohepatitis (NASH) is an advanced form of NAFLD can progress to liver cirrhosis and hepatocellular carcinoma (HCC). Recently, the prognosis of NAFLD/NASH has been reported to be dependent on liver fibrosis degree. Liver biopsy remains the gold standard, but it has several issues that must be addressed, including its invasiveness, cost, and inter-observer diagnosis variability. To solve these issues, a variety of noninvasive tests (NITs) have been in development for the assessment of NAFLD progression, including blood biomarkers and imaging methods, although the use of NITs varies around the world. The aim of the Japan NASH NIT (JANIT) Forum organized in 2020 is to advance the development of various NITs to assess disease severity and/or response to treatment in NAFLD patients from a scientific perspective through multi-stakeholder dialogue with open innovation, including clinicians with expertise in NAFLD/NASH, companies that develop medical devices and biomarkers, and professionals in the pharmaceutical industry. In addition to conventional NITs, artificial intelligence will soon be deployed in many areas of the NAFLD landscape. To discuss the characteristics of each NIT, we conducted a SWOT (strengths, weaknesses, opportunities, and threats) analysis in this study with the 36 JANIT Forum members (16 physicians and 20 company representatives). Based on this SWOT analysis, the JANIT Forum identified currently available NITs able to accurately select NAFLD patients at high risk of NASH for HCC surveillance/therapeutic intervention and evaluate the effectiveness of therapeutic interventions.

    The prognosis of nonalcoholic fatty liver disease (NAFLD) patients depends on liver-related events (LREs), extrahepatic cancers, and major adverse cardiovascular events (MACEs). The fibrosis-4 (FIB-4) index is one of the most reliable and useful predictors of the degree of liver fibrosis. Recent studies have reported that the FIB-4 index is also useful for predicting LREs and MACEs in NAFLD patients. In the present study, we investigated the prognostic value of the FIB-4 index in NAFLD patients. A total of 506 biopsy-confirmed NAFLD patients from six hepatology centers in Japan from 2002 to 2013 were enrolled in this study. Of these NAFLD patients, 353 were available for more than 100 days of follow-up and did not exhibit events (LREs, extrahepatic cancers, MACEs) at the time of entry. The mean follow-up duration of all the subjects was 2716 ± 1621 days (102-7483 days). New LREs (hepatocellular carcinoma (HCC) (n = 8), decompensation (n = 11), bleeding varices (n = 8)) developed in 18 patients. Twenty-four and twelve patients developed extrahepatic cancers and MACEs, respectively. The median FIB-4 index was 1.255; we divided our cohort into two groups according to this (FIB4 Low, FIB4 Hi). The incidence of HCC tended to be higher in FIB4 Hi (n = 7) than in FIB4 Low (n = 1). The incidence of LREs was significantly higher in FIB4 Hi (n = 17) than in FIB4 Low (n = 1). The incidence of extrahepatic cancers was significantly higher in FIB4 Hi (n = 20) than in FIB4 Low (n = 4); the incidence of MACEs was also significantly higher in FIB4 Hi (n = 10) than in FIB4 Low (n = 2). The FIB-4 index is a useful biomarker for predicting not only LREs but also extrahepatic cancers and MACEs.

    BACKGROUND& AIMS: Older age, type 2 diabetes mellitus (T2DM), and obesity are known risk factors for liver-related events (LRE). We investigated the impacts of T2DM and obesity on LRE according to age in Japanese patients with nonalcoholic fatty liver disease (NAFLD). METHODS: We performed a subanalysis of a retrospective cohort study (CLIONE in Asia), including 1,395 patients with biopsy-proven NAFLD. The median follow-up was 4.6 years. RESULTS: The median age was 57 years, and 36.2% had T2DM. The median body mass index (BMI) was 27.4, and 28.5% were severely obese (BMI ≥ 30). During follow-up, 37 patients developed hepatocellular carcinoma (HCC), and 58 patients developed LRE. In patients younger than 65 years, advanced fibrosis (hazard ratio [HR] 7.69, p < 0.001) and T2DM (HR 3.37, p = 0.017) were HCC risk factors, and advanced fibrosis (HR 9.40, p < 0.001) and T2DM (HR 2.51, p = 0.016) were LRE risk factors. In patients 65 years and older, advanced fibrosis (HR 4.24, p = 0.010) and obesity (HR 4.60, p = 0.006) were HCC risk factors, and advanced fibrosis (HR 4.22, p = 0.002) and obesity (HR 4.22, p = 0.002) were LRE risk factors. CONCLUSION: T2DM and obesity contributed to LRE in younger and older patients, respectively, along with advanced fibrosis. Therefore, controlling T2DM in patients younger than 65 years and controlling weight in patients 65 years and older could prevent LRE. The development of age-dependent screening and management strategies is necessary for patients with NAFLD.

    Cholangiocarcinoma (CC) has a poor prognosis and different driver genes depending on the site of onset. Intrahepatic CC is the second-most common liver cancer after hepatocellular carcinoma, and novel therapeutic targets are urgently needed. The present study was conducted to identify novel therapeutic targets by exploring differentially regulated genes in human CC. MicroRNA (miRNA) and mRNA microarrays were performed using tissue and serum samples obtained from 24 surgically resected hepatobiliary tumor cases, including 10 CC cases. We conducted principal component analysis to identify differentially expressed miRNA, leading to the identification of miRNA-3648 as a differentially expressed miRNA. We used an in silico screening approach to identify its target mRNA, the tumor suppressor Sloan Kettering Institute (SKI). SKI protein expression was decreased in human CC cells overexpressing miRNA-3648, endogenous SKI protein expression was decreased in human CC tumor tissues, and endogenous SKI mRNA expression was suppressed in human CC cells characterized by rapid growth. SKI-overexpressing OZ cells (human intrahepatic CC cells) showed upregulation of cyclin-dependent kinase inhibitor p21 mRNA and protein expression and suppressed cell proliferation. Nuclear expression of CDT1 (chromatin licensing and DNA replication factor 1), which is required for the G1/S transition, was suppressed in SKI-overexpressing OZ cells. SKI knockdown resulted in the opposite effects. Transgenic p21-luciferase was activated in SKI-overexpressing OZ cells. These data indicate SKI involvement in p21 transcription and that SKI-p21 signaling causes cell cycle arrest in G1, suppressing intrahepatic CC cell growth. Therefore, SKI may be a potential therapeutic target for intrahepatic CC.

    BACKGROUND AND AIM: We evaluated the efficacy of rechallenge transcatheter arterial chemoembolization (TACE) after lenvatinib (LEN) treatment in patients with previous TACE failure/refractoriness. METHODS: We enrolled 63 consecutive patients with a history of TACE failure/refractoriness prior to LEN treatment as a first-line systemic therapy. We reviewed the clinical backgrounds and courses of the patients. RESULTS: In total, 25 patients underwent rechallenge TACE after LEN due to LEN-refractoriness (17 cases) or intolerance (8 cases). A complete or partial response was obtained for 13 (65.0%) of the 20 patients whose therapeutic effects were determined. The survival rate of patients who underwent rechallenge TACE was significantly higher than that of patients who did not undergo rechallenge TACE (median survival time, not reached vs 403 days, P = 0.015). Rechallenge TACE significantly reduced the risk of death in univariate (hazard ratio [HR] 0.24, 95% confidence interval [CI] 0.08-0.69, P = 0.008) and multivariate analyses (HR 0.26, 95% CI 0.08-0.80, P = 0.019). If complete or partial response was obtained by rechallenge TACE, the median survival time of these patients was significantly longer than those of the progressive disease (PD) group (P = 0.05), and the median survival time of the PD group after rechallenge TACE was not different from that of the group who did not undergo rechallenge TACE (P = 0.36). We did not observe a decrease in the ALBI score after TACE. CONCLUSION: Rechallenge TACE after LEN is an effective treatment that may result in a favorable prognosis.

    We previously demonstrated that Mac-2 binding protein (M2BP) is a useful biomarker for nonalcoholic fatty liver disease (NAFLD), particularly NAFLD fibrosis prediction. In the present study, we investigated the prognostic value of M2BP in patients with NAFLD. A total of 506 patients with biopsy-confirmed NAFLD from 2002 to 2013 were enrolled in this study in Japan. Three hundred fifty-three of these patients with NAFLD were available for follow-up for more than 100 days and showed no liver-related events at the time of entry. Liver-related events were defined as hepatocellular carcinoma (HCC), decompensation, and gastroesophageal varices with variceal treatment. The mean follow-up duration of all the subjects was 2716 ± 1621 days (102-7483 days). Eighteen patients developed new liver-related events (HCC, 8; decompensation, 11; varices, 8). Nine patients developed cardiovascular disease (CVD), and 24 patients developed new cancers in other organs. The median serum M2BP level was 1.603 μg/mL, and we divided our cohort into two groups according to the serum M2BP level: M2BP low group (M2BP Low) and M2BP high group (M2BP Hi). The incidence of HCC was significantly higher in M2BP Hi (n = 8) than in M2BP Low (n = 0). The incidence of liver-related events was significantly higher in M2BP Hi (n = 16) than in M2BP Low (n = 2). The incidences of death, CVD events, and cancer in other organs were not different between the groups. Interestingly, the incidence of colorectal cancer was significantly higher in M2BP Hi (n = 5) than in M2BP Low (n = 0). Conclusion: M2BP is a useful biomarker to predict liver-related events, particularly HCC. Additionally, M2BP is a potential predictive biomarker of colorectal cancer development.

    BACKGROUND AND AIMS: The coronavirus disease 2019 (COVID-19) pandemic precipitated lifestyle changes. We aimed to clarify whether COVID-19-induced lifestyle changes affected the development of metabolic dysfunction-associated fatty liver disease (MAFLD). METHODS: This retrospective longitudinal study included 973 participants who underwent health check-ups between 2018 and 2020. We used data from the MedCity21 health examination registry. Participants' clinical characteristics and lifestyle habits were investigated. Independent lifestyle predictors of MAFLD development before the pandemic (2018-2019) and during the pandemic (2019-2020) were identified using logistic regression analysis. RESULTS: In 2018, 261 (27%) patients were diagnosed with MAFLD. Before the pandemic, 22 patients developed new MAFLD. During this time, routine late-night meals were identified as an independent lifestyle predictor of MAFLD development (hazard ratio [HR] 2.54, 95% confidence interval [CI] 1.02-6.36, P = .046). In contrast, 44 patients developed new MAFLD during the pandemic. During this time, higher daily alcohol intake was identified as an independent lifestyle predictor of MAFLD development (HR 1.03, 95% CI 1.01-1.05, P = .008). In participants aged <60 years, daily alcohol intake and the proportion of participants who ate 2 times/day were significantly higher in patients who developed MAFLD during the pandemic than in those who did not. In participants aged ≥60 years, no lifestyle habits were associated with MAFLD development before or during the pandemic. CONCLUSIONS: New MAFLD diagnoses increased during the COVID-19 pandemic. Changes in lifestyle factors, particularly in those aged <60 years, must be monitored and addressed as the pandemic continues.

    <p><b>Objective </b>Mapping the long-term prognosis of Budd-Chiari syndrome (BCS) is difficult, as the prognosis is associated with changes in the liver function. The present study evaluated the time course changes in the liver function in a treatment group with percutaneous old balloon angioplasty (POBA) and a non-treatment group using the albumin-bilirubin score (ALBI) and Child-Pugh score during long-term follow-up. </p><p><b>Methods </b>In this retrospective study, 13 consecutive patients diagnosed with BCS at our hospital between 2007 and 2020 were categorized into a treatment group (n=8), which received POBA, and a non-treatment group (n=5). Differences in the liver function in the ALBI and Child-Pugh scores between the initial visit and one- and three-year follow-up were calculated and statistically evaluated. We investigated the changes in the liver function during the long-term follow-up, including events such as re-stenosis and re-treatment. </p><p><b>Results </b>While the Child-Pugh scores in the treatment group did not differ significantly between the initial visit and 1- or 3-year follow-up, the ALBI scores in this group improved significantly between the initial visit and the 1- or 3-year follow-up visit (p=0.0078 and 0.0156, respectively). The liver function according to the ALBI score in the treatment group showed gradual improvement from the initial value but gradual worsening in the non-treatment group. The ALBI scores also revealed that the liver function varies according to re-stenosis and re-POBA in BCS patients. </p><p><b>Conclusion </b>Unlike the Child-Pugh score, the ALBI score was able to capture changes in the liver function of BCS patients during the long-term course of BCS. </p>

    Soluble immune checkpoint molecules are emerging novel mediators of immune regulation. However, it is unclear whether soluble immune checkpoint proteins affect the development of hepatocellular carcinoma (HCC) during nucleos(t)ide analogue (NA) treatment in patients with chronic hepatitis B virus infection. This study included 122 NA-naïve patients who received NA therapy. We assessed the associations of clinical factors, including soluble immune checkpoint proteins, with HCC development during NA treatment. The baseline serum concentrations of 16 soluble immune checkpoint proteins were measured using multiplexed fluorescent bead-based immunoassay. In total, 13 patients developed HCC during the follow-up period (median duration, 4.3 years). Of the 16 proteins, soluble inducible T-cell co-stimulator (≥ 164.71 pg/mL; p = 0.014), soluble programmed cell death-1 (sPD-1) (≤ 447.27 pg/mL; p = 0.031), soluble CD40 (≤ 493.68 pg/mL; p = 0.032), and soluble herpes virus entry mediator (≤ 2470.83 pg/mL; p = 0.038) were significantly associated with HCC development (log-rank test). In multivariate analysis, an sPD-1 level ≤ 447.27 pg/mL (p = 0.014; hazard ratio [HR], 4.537) and α-fetoprotein level ≥ 6.4 ng/mL (p = 0.040; HR, 5.524) were independently and significantly associated with HCC development. Pre-treatment sPD-1 is a novel predictive biomarker for HCC development during NA treatment.

    Hepatocellular carcinoma (HCC) has high recurrence rates. HCC sometimes progresses from early-stage HCC (Barcelona Clinic Liver Cancer [BCLC] stage 0/A) to advanced-stage HCC after repeated recurrences and treatments. HCC progression deteriorates quality of life and prognosis. However, the effect of direct-acting antiviral (DAA)-induced sustained virologic response (SVR) on HCC progression remains uninvestigated. We conducted a retrospective cohort study of patients with hepatitis C virus-related HCC with BCLC stage 0/A diagnosed for the first time and treated by curative resection or ablation. Using a time-varying method, we estimated the risk of tumour progression (defined as progression to BCLC stage B-D) and liver-related death and the characteristics of repeated recurrence. Overall, 165 patients were enrolled. Following curative HCC treatment, 72 patients received DAA therapy (DAA-treated group), whereas 93 did not (untreated group). Approximately 75% of the recurrences were at an early stage and expected to be disease-free by retreatment. We recorded 56 tumour progressions, of which 60.7% were observed after second recurrence. Multivariate adjusted time-varying Cox regression analysis showed that the DAA-induced SVR significantly reduced the risk of tumour progression (hazard ratio [HR] 0.28; p = .001) and liver-related death (HR 0.12; p < .001). The annual incidence of HCC treatment until tumour progression was 82.8% and 23.9% in the untreated and DAA-treated groups, respectively (HR 0.30; p < .001). DAA-induced SVR significantly reduced the risk for tumour progression and liver-related death and the frequency of HCC treatment following curative treatment for HCC at BCLC stage 0/A.

    Sodium glucose cotransporter-2 inhibitors (SGLT2is) are now widely used to treat diabetes, but their effects on nonalcoholic fatty liver disease (NAFLD) remain to be determined. We aimed to evaluate the effects of SGLT2is on the pathogenesis of NAFLD. A multicenter, randomized, controlled trial was conducted in patients with type 2 diabetes with NAFLD. The changes in glycemic control, obesity, and liver pathology were compared between participants taking ipragliflozin (50 mg/day for 72 weeks; IPR group) and participants being managed without SGLT2is, pioglitazone, glucagon-like peptide-1 analogs, or insulin (CTR group). In the IPR group (n = 25), there were significant decreases in hemoglobin A1c (HbA1c) and body mass index (BMI) during the study (HbA1c, -0.41%, P < 0.01; BMI, -1.06 kg/m2 , P < 0.01), whereas these did not change in the CTR group (n = 26). Liver pathology was evaluated in 21/25 participants in the IPR/CTR groups, and hepatic fibrosis was found in 17 (81%) and 18 (72%) participants in the IPR and CTR groups at baseline. This was ameliorated in 70.6% (12 of 17) of participants in the IPR group and 22.2 % (4 of 18) of those in the CTR group (P < 0.01). Nonalcoholic steatohepatitis (NASH) resolved in 66.7% of IPR-treated participants and 27.3% of CTR participants. None of the participants in the IPR group developed NASH, whereas 33.3% of the CTR group developed NASH. Conclusion: Long-term ipragliflozin treatment ameliorates hepatic fibrosis in patients with NAFLD. Thus, ipragliflozin might be effective for the treatment and prevention of NASH in patients with diabetes, as well as improving glycemic control and obesity. Therefore, SGLT2is may represent a therapeutic choice for patients with diabetes with NAFLD, but further larger studies are required to confirm these effects.

    Interleukin (IL)-19, a member of the IL-10 family, is an anti-inflammatory cytokine produced primarily by macrophages. Nonalcoholic steatohepatitis (NASH) is a disease that has progressed from nonalcoholic fatty liver disease (NAFLD) and is characterized by inflammation and fibrosis. We evaluated the functions of IL-19 in a NAFLD/NASH mouse model using a 60% high fat diet with 0.1% methionine, without choline, and with 2% cholesterol (CDAHFD). Wild-type (WT) and IL-19 gene-deficient (KO) mice were fed a CDAHFD or standard diet for 9 weeks. Liver injury, inflammation, and fibrosis induced by CDAHFD were significantly worse in IL-19 KO mice than in WT mice. IL-6, TNF-α, and TGF-β were significantly higher in IL-19 KO mice than in WT mice. As a mechanism using an in vitro experiment, palmitate-induced triglyceride and cholesterol contents were decreased by the addition of IL-19 in HepG2 cells. Furthermore, addition of IL-19 decreased the expression of fatty acid synthesis-related enzymes and increased ATP content in HepG2 cells. The action of IL-19 in vitro suppressed lipid metabolism. In conclusion, IL-19 may play an important role in the development of steatosis and fibrosis by directly regulating liver metabolism and may be a potential target for the treatment of liver diseases.

    Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver diseases worldwide, including in Japan. The Japanese Society of Gastroenterology (JSGE) and the Japanese Society of Hepatology (JSH) have established the Japanese NAFLD/NASH guidelines in 2014 and revised these guidelines in 2020. As described in these guidelines, weight reduction by diet and/or exercise therapy is important for the treatment of NAFLD patients. The I148M single nucleotide polymorphism (rs738409 C > G) of PNPLA3 (patatin-like phospholipase domain-containing 3 protein) is widely known to be associated with the occurrence and progression of NAFLD. In the Japanese, the ratio of PNPLA3 gene polymorphisms found is approximately 20%, which is higher than that found in Westerners. In addition, the ratio of lean NAFLD patients is also higher in Japan than in Western countries. Therefore, the method for lifestyle guidance for the NAFLD patients in Japan would be different from that for the people in Western countries. The problems in the treatment of NAFLD patients include alcohol consumption and sarcopenia. Therefore, guidelines that can help clinicians treat Japanese patients with NAFLD are needed. In this expert review, we summarize evidence-based interventions for lifestyle modification (diet, exercise, alcohol, and sarcopenia) for the treatment of patients with NAFLD, especially from Japan and Asian countries.

    Non-alcoholic steatohepatitis (NASH), a severe form of non-alcoholic fatty liver disease (NAFLD), can progress to cirrhosis, hepatocellular carcinoma (HCC), and hepatic failure/liver transplantation. Indeed, NASH will soon be the leading cause of HCC and liver transplantation. Lifestyle intervention represents the cornerstone of NASH treatment, but it is difficult to sustain. However, no pharmacotherapies for NASH have been approved. Oxidative stress has been implicated as one of the key factors in the pathogenesis of NASH. Systematic reviews with meta-analyses have confirmed that vitamin E reduces transaminase activities and may resolve NASH histopathology without improving hepatic fibrosis. However, vitamin E is not recommended for the treatment of NASH in diabetes, NAFLD without liver biopsy, NASH cirrhosis, or cryptogenic cirrhosis. Nevertheless, vitamin E supplementation may improve clinical outcomes in patients with NASH and bridging fibrosis or cirrhosis. Further studies are warranted to confirm such effects of vitamin E and that it would reduce overall mortality/morbidity without increasing the incidence of cardiovascular events. Future clinical trials of the use of vitamin E in combination with other anti-fibrotic agents may demonstrate an additive or synergistic therapeutic effect. Vitamin E is the first-line pharmacotherapy for NASH, according to the consensus of global academic societies.

    This study aimed to prove that the FibroScan-aspartate aminotransferase (FAST) scores can be used to stratify disease severity in a Japanese cohort with fatty liver diseases [metabolic dysfunction-associated fatty liver disease (MAFLD) and nonalcoholic fatty liver disease (NAFLD)]. All the participants (n = 2254) underwent liver stiffness measurements and controlled attenuation parameter assessments. We compared the clinical characteristics of the patients with MAFLD and NAFLD using the FAST scores and explored the independent determinants of FAST scores ≥ 0.35, which indicated possible progressive disease. Overall, MAFLD was diagnosed in 789 patients (35.0%), while NAFLD was diagnosed in 618 (27.4%). The proportion of patients that had a condition that suggested progressive liver disease was higher in those with MAFLD than in those with NAFLD [68 (8.6%) vs 48 (7.7%)]. The area under the receiver-operating characteristic curve of the FAST score for diagnosing advanced fibrosis was 0.969 in MAFLD and 0.965 in NAFLD. Multivariate analyses determined that diabetes mellitus, alanine aminotransferase (ALT) levels, fatty liver index, and Fibrosis-4 index independently predict FAST scores ≥ 0.35 in patients with MAFLD. ALT levels had the strongest correlation with the FAST scores (p = 0.7817). The FAST score could stratify the disease severity in the Japanese cohort with fatty liver diseases.

    Liver fibrosis reflects tissue scarring in the liver due to the accumulation of excessive extracellular matrix in response to chronically persistent liver injury. Hepatocyte cell death can trigger capillarization of liver sinusoidal endothelial cells, stimulation of immune cells including macrophages and Kupffer cells, and activation of hepatic stellate cells (HSCs), resulting in progression of liver fibrosis. Liver cirrhosis is the terminal state of liver fibrosis and is associated with severe complications, such as liver failure, portal hypertension, and liver cancer. Nevertheless, effective therapy for cirrhosis has not yet been established, and liver transplantation is the only radical treatment for severe cases. Studies investigating HSC activation and regulation of collagen production in the liver have made breakthroughs in recent decades that have advanced the knowledge regarding liver fibrosis pathophysiology. In this review, we summarize molecular mechanisms of liver fibrosis and discuss the development of novel anti-fibrotic therapies.

    BACKGROUND AND AIM: The Gut and Obesity in Asia Workgroup recently reported that a two-step approach using fibrosis scores followed by liver stiffness measurement (LSM) could accurately detect patients with non-alcoholic fatty liver disease (NAFLD) having advanced fibrosis in low-risk fibrosis populations. This study aimed to validate the utility of this approach using a Japanese health checkup registry. METHODS: This cross-sectional study included subjects who underwent a health checkup from 2014 to 2019. Using estimated fibrosis stage measured by LSM as a standard, we calculated the percentage of misclassification from assessments made based on fibrosis scores (NAFLD fibrosis score [NFS] or Fibrosis-4 score [FIB-4]) and LSM, alone or in combination. RESULTS: Of 630 subjects with NAFLD, 4 (0.8%) had advanced fibrosis. In the first-step evaluation, only 21.4-38.0% of subjects needed further testing. This approach was associated with a high specificity of approximately 100% and a negative predictive value of 99.7%. The percentage of misclassification based on NFS or FIB-4 values followed by LSM in all subjects and using LSM after NFS or FIB-4 determination only in subjects with indeterminate/high NFS or FIB-4 values (two-step approach) was 0% and 0.3% and 0.16% and 0.3%, respectively. In addition, very few false negatives occurred for both NFS and FIB-4. CONCLUSION: The two-step approach helps to identify the subjects with NAFLD who have advanced fibrosis during a routine health checkup and is associated with only a few false negatives.

    This study aimed to examine whether the diagnostic accuracy of four noninvasive tests (NITs) for detecting advanced fibrosis in nonalcoholic fatty liver disease (NAFLD) is maintained or is inferior to with or without the presence of type 2 diabetes. Overall, 874 patients with biopsy-proven NAFLD were enrolled. After propensity-score matching by age, sex, and the prevalence of dyslipidemia, 311 patients were enrolled in each group of with or without diabetes. To evaluate the effect of diabetes, we compared the diagnostic accuracy of the fibrosis-4 (FIB-4) index, the NAFLD fibrosis score (NFS), the aspartate aminotransferase to platelet ratio index (APRI), and type IV collagen 7S (COL4-7S) in patients with NAFLD with and without diabetes. The areas under the receiver operating characteristic curve (AUROC) for identifying advanced fibrosis in patients without diabetes were 0.879 for the FIB-4 index, 0.851 for the NFS, 0.862 for the APRI, and 0.883 for COL4-7S. The AUROCs in patients with diabetes were 0.790 for the FIB-4 index, 0.784 for the NFS, 0.771 for the APRI, and 0.872 for COL4-7S. The AUROC of COL4-7S was significantly larger than that of the other NITs in patients with NAFLD with diabetes than in those without diabetes. The optimal high and low cutoff points of COL4-7S were 5.9 ng/mL and 4.8 ng/mL, respectively. At the low cutoff point, the accuracy of COL4-7S was better than that of the other NITs, especially in patients with diabetes. Conclusion: COL4-7S measurement might be the best NIT for identifying advanced fibrosis in NAFLD, especially in NAFLD with diabetes.

    The prevalence of obesity or metabolic syndrome is increasing worldwide (globally metabodemic). Approximately 25% of the adult general population is suffering from nonalcoholic fatty liver disease (NAFLD), which has become a serious health problem. In 2020, global experts suggested that the nomenclature of NAFLD should be updated to metabolic-dysfunction-associated fatty liver disease (MAFLD). Hepatic fibrosis is the most significant determinant of all cause- and liver -related mortality in MAFLD. The non-invasive test (NIT) is urgently required to evaluate hepatic fibrosis in MAFLD. The fibrosis-4 (FIB-4) index is the first triaging tool for excluding advanced fibrosis because of its accuracy, simplicity, and cheapness, especially for general physicians or endocrinologists, although the FIB-4 index has several drawbacks. Accumulating evidence has suggested that vibration-controlled transient elastography (VCTE) and the enhanced liver fibrosis (ELF) test may become useful as the second step after triaging by the FIB-4 index. The leading cause of mortality in MAFLD is cardiovascular disease (CVD), extrahepatic malignancy, and liver-related diseases. MAFLD often complicates chronic kidney disease (CKD), resulting in increased simultaneous liver kidney transplantation. The FIB-4 index could be a predictor of not only liver-related mortality and incident hepatocellular carcinoma, but also prevalent and incident CKD, CVD, and extrahepatic malignancy. Although NITs as milestones for evaluating treatment efficacy have never been established, the FIB-4 index is expected to reflect histological hepatic fibrosis after treatment in several longitudinal studies. We here review the role of the FIB-4 index in the management of MAFLD.

    Background and Aim: Hepatitis C virus (HCV) infection causes insulin resistance and diabetes as extrahepatic manifestations. We aimed to analyze the effect of HCV eradication by direct-acting antiviral (DAA) agents on glucose tolerance. Methods: The hemoglobin A1c (HbA1c) of 272 patients with HCV infection who achieved a sustained virologic response (SVR) was analyzed at baseline before DAA treatment, at the end of DAA therapy (ETR), and 12 weeks after therapy (Post12W). Results: There were no significant differences in HbA1c between baseline, ETR, and Post12W in the overall patients. When the data were stratified according to the presence or absence of diabetes, median HbA1c significantly decreased from baseline (7.2%) to ETR (6.8%) and Post12W (6.8%) in the 55 patients with diabetes, whereas there were no significant changes in the patients without diabetes. Basal HbA1c, fasting plasma glucose, and age were independently associated with the changes in HbA1c according to multivariate analysis, and the predictive formula for changes in HbA1c was found to be ΔHbA1c (%) = 1.449-0.4* HbA1c (%) + 0.012 × Age (year). There were no changes in body mass in diabetic or nondiabetic patients. In diabetic patients taking medication, 63.4% of patients needed less medication. Conclusions: Eradication of HCV improves glycemic control, indicated by a 0.4% decrease in HbA1c in diabetes.

    Stress can affect our body and is known to lead to some diseases. However, the influence on the development of nonalcohol fatty liver disease (NAFLD) remains unknown. This study demonstrated that chronic restraint stress attenuated hepatic lipid accumulation via elevation of hepatic β-muricholic acid (βMCA) levels in the development of nonalcoholic steatohepatitis (NASH) in mice. Serum cortisol and corticosterone levels, i.e., human and rodent stress markers, were correlated with serum bile acid levels in patients with NAFLD and methionine- and choline-deficient (MCD) diet-induced mice, respectively, suggesting that stress is related to bile acid (BA) homeostasis in NASH. In the mouse model, hepatic βMCA and cholic acid (CA) levels were increased after the stress challenge. Considering that a short stress enhanced hepatic CYP7A1 protein levels in normal mice and corticosterone increased CYP7A1 protein levels in primary mouse hepatocytes, the enhanced Cyp7a1 expression was postulated to be involved in the chronic stress-increased hepatic βMCA level. Interestingly, chronic stress decreased hepatic lipid levels in MCD-induced NASH mice. Furthermore, βMCA suppressed lipid accumulation in mouse primary hepatocytes exposed to palmitic acid/oleic acid, but CA did not. In addition, Cyp7a1 expression seemed to be related to lipid accumulation in hepatocytes. In conclusion, chronic stress can change hepatic lipid accumulation in NASH mice, disrupting BA homeostasis via induction of hepatic Cyp7a1 expression. This study discovered a new βMCA action in the liver, indicating the possibility that βMCA is available for NAFLD therapy.

    INTRODUCTION: Lenvatinib has been approved as a systemic therapy for patients with unresectable hepatocellular carcinoma (HCC). We recently experienced lenvatinib-induced tumor-related hemorrhage in patients with HCC. The full details of tumor-related hemorrhage as a lenvatinib-related adverse event have not been elucidated. METHODS: This was a retrospective single-center study that enrolled consecutive patients treated with lenvatinib for unresectable HCC from April 2018 to February 2020. RESULTS: Sixty-eight consecutive patients were enrolled in this study. Among them, 5 cases developed intraperitoneal or intratumoral hemorrhages. The patients with hemorrhage had larger tumors (maximum tumor size, 97.5 ± 46.4 and 38.2 ± 28.8 mm, respectively; p = 0.009) than the patients without hemorrhage. The dosing period of lenvatinib (median, 3 and 93 days, respectively; p < 0.001) and the survival time from initial administration of lenvatinib (median, 77 and 495 days, respectively; p < 0.001) of the patients with hemorrhage were shorter than those of the patients without hemorrhage. Especially, in 4 cases with large HCCs (maximum tumor diameter was >90 mm), tumor hemorrhage with vascular lake-like phenomenon was evident, although most tumor blood flow was suppressed. DISCUSSION/CONCLUSION: It becomes clear that lenvatinib treatment brings about tumor-related hemorrhages despite rapid suppression of tumor blood flow. We speculate that lenvatinib quickly blocks the feeding circulation, resulting in tumor hemorrhage by necrosis. Clinicians should pay careful attention to the development of life-threatening hemorrhages when treating large HCCs with lenvatinib.

    <p>A 59 year-old-Japanese female was referred to our hospital for tumor-induced abdominal pain. Dynamic computed tomography (CT) demonstrated a tumor, 88×73 mm in diameter, which was adherent to the caudate lobe of the liver and pancreas. Based on these findings, we performed a laparotomy with a preoperative diagnosis of hepatocellular carcinoma (HCC) originating from the caudate lobe of the liver. The tumor could be dissected from the liver, however, it had infiltrated into the common hepatic artery, leading to incomplete extirpation of the tumor. Histological examination revealed that the tumor was an ectopic HCC. Lenvatinib mesylate (lenvatinib) was used as systemic therapy for growth of the remnant tumor 16 days after surgery. CT performed during two months after initiating lenvatinib revealed that the tumor size had reduced with a decrease in vascularity, which was deemed to be a partial response. CT performed three months after the initiation of lenvatinib demonstrated regrowth of the tumor. The patient died of HCC 164 days after surgery.</p>

    Hypothyroidism is a common adverse event of lenvatinib therapy for hepatocellular carcinoma (HCC), whereas thyrotoxicosis has rarely been reported in clinical trials. A 74-year-old man complaining of abdominal pain was found to have liver tumors and paraaortic lymphadenopathy. The intrahepatic lesions were diagnosed as HCC by angiography and treated with transcatheter arterial chemoembolization. Although localized prostate cancer was discovered incidentally, the etiology of paraaortic lymphadenopathy was assumed to be metastatic HCC. Lenvatinib 12 mg/day was started when his thyroid function tests were almost normal but was interrupted because of thyrotoxicosis. The patient was negative for tested thyroid autoantibodies. Color Doppler ultrasonography detected reduced thyroid blood flow, suggesting destructive thyroiditis. Although he resumed lenvatinib at 8 mg/day once his serum level of free thyroxine normalized, thyrotoxicosis recurred. Subsequently, he suffered hypothyroidism, which exacerbated despite levothyroxine replacement. Lenvatinib was discontinued as it was ineffective against the paraaortic lymph node metastasis, and external-beam radiotherapy was performed. After the completion of radiotherapy, the thyroid dysfunction significantly improved. In summary, lenvatinib for HCC can induce transient thyrotoxicosis followed by hypothyroidism, which is compatible with destructive thyroiditis. During lenvatinib therapy, close monitoring of thyroid function and appropriate management of thyrotoxicosis as well as hypothyroidism are essential.

    Background and Aim: We assessed direct-acting antiviral (DAA) treatment for patients with hepatitis C virus (HCV) and a history of injection drug use (IDU) in Japan.Method: This retrospective observational study was based on clinical records. Overall, 804 DAA-naive HCV-infected patients were enrolled, treated with a 12-week regimen of DAAs, and had available information about a history of IDU. Anti-HCV efficacy was defined as a sustained viral response 12 weeks post-treatment (SVR12) only in patients who were assessed after 12 weeks [modified intention-to-treat (ITT) analyses]. We compared the antiviral effect between patients with (past-IDU) and without a history of IDU (non-IDU). We also evaluated the characteristics of each group, including the overall dropout rate and economic background.Results: Overall, 78 (9.7%) patients had a history of IDU. Compared to the non-IDU group at baseline, the past-IDU group consisted of predominantly male and younger patients infected with HCV genotype 2. Overall, 3% (3/78) and 16% (116/726) of the patients had cirrhosis in the past-IDU and non-IDU group, respectively. There was a significantly higher rate of welfare recipients in the past-IDU group. SVR rate was 97% (59/61) in the past-IDU group and 99% (689/699) in the non-IDU group. The cumulative rate of dropout from an aftercare program was high in the past-IDU group (P < 0.01).Conclusions: DAAs had a remarkable anti-HCV effect in patients with past-IDU who continued in an aftercare program. It is necessary to understand the characteristics of past-IDU patients to establish a support system for aftercare programs.

    Background/Purpose Although ursodeoxycholic acid (UDCA) is a first-line treatment for primary biliary cholangitis (PBC), 20%-30% of patients with PBC exhibit an incomplete response to UDCA. Recently, the UDCA Response Score was proposed for predicting response to UDCA using pretreatment parameters in patients with PBC. We aimed to validate the UDCA Response Score in Japanese patients with PBC.Methods Registry data of Japanese patients (n = 873) were collected. Patients with data on all clinical parameters required for calculating the UDCA Response Score were selected. The endpoint was UDCA response, defined as alkaline phosphatase All parameters were available in 804 patients (male/female = 120/684, age 58.9 [interquartile range 51.1-66.9] years). Bezafibrate was commenced within 12 months of UDCA in 78 patients (9.7%) because of the lack of an early response. We found that the endpoint was not reached in these 78 patients, and the area under the receiver operating characteristic curve (AUROC) of the score was 0.74 (95% confidence interval [CI] 0.70-0.79). The AUROC was 0.77 (95% CI 0.70-0.83) in patients undergoing UDCA monotherapy (n = 726). Finally, the AUROC of the modified UDCA Response Score using only data from the treatment start date was 0.80 (95% CI 0.70-0.90) in patients receiving a combination therapy of UDCA and bezafibrate (n = 160).Conclusion The validity of the UDCA Response Score was acceptable in Japanese patients; this score will be informative in patients treated with a combination therapy of UDCA and bezafibrate.

    INTRODUCTION AND OBJECTIVES: We examined whether Mac-2-binding protein glycosylation isomer (M2BPGi) levels could be a predictive marker for the presence of esophagogastric varices (EGV) in cirrhotic patients after hepatitis C virus (HCV) eradication with direct-acting antivirals (DAAs). PATIENTS AND METHODS: A total of 102 cirrhotic patients with HCV infection treated with DAAs were enrolled. Esophagogastroduodenoscopy was performed in 84 of the patients before treatment (Cohort A), in 66 after treatment (Cohort B), and in 48 at both time points (Cohort C). We examined factors associated with EGV before and after DAA treatment. RESULTS: In Cohort A, M2BPGi levels and liver stiffness were significantly higher in the EGV-positive group than the EGV-negative group (p=0.034, and p=0.042, respectively). The proportion of EGV-positive patients with before-treatment levels of M2BPGi ≧ 7.3 C.O.I. was significantly higher than in patients with M2BPGi levels<7.3 C.O.I. (p=0.015). In Cohort B, M2BPGi levels were significantly higher in the EGV-positive group than EGV-negative group (p=0.003). The proportion of EGV-positive patients with after-treatment levels of M2BPGi ≧ 3.4 C.O.I. was significantly higher than in patients with M2BPGi levels<3.4C.O.I. (p=0.001). In Cohort C, M2BPGi levels decreased during DAA treatment regardless of EGV development, but there was no significant difference in the reduction of M2BPGi among the EGV-improvement, EGV-invariant, and EGV-exacerbation groups (p=0.659). CONCLUSIONS: M2BPGi levels may be a novel serum marker for the presence of EGV before and after DAA treatment.

    Liver-related diseases are the third-leading causes (9.3%) of mortality in type 2 diabetes (T2D) in Japan. T2D is closely associated with nonalcoholic fatty liver disease (NAFLD), which is the most prevalent chronic liver disease worldwide. Nonalcoholic steatohepatitis (NASH), a severe form of NAFLD, can lead to hepatocellular carcinoma (HCC) and hepatic failure. No pharmacotherapies are established for NASH patients with T2D. Though vitamin E is established as a first-line agent for NASH without T2D, its efficacy for NASH with T2D recently failed to be proven. The effects of pioglitazone on NASH histology with T2D have extensively been established, but several concerns exist, such as body weight gain, fluid retention, cancer incidence, and bone fracture. Glucagon-like peptide 1 (GLP-1) receptor agonists and sodium-glucose cotransporter 2 (SGLT2) inhibitors are expected to ameliorate NASH and NAFLD (LEAN study, LEAD trial, and E-LIFT study). Among a variety of SGLT2 inhibitors, dapagliflozin has already entered the phase 3 trial (DEAN study). A key clinical need is to determine the kinds of antidiabetic drugs that are the most appropriate for the treatment of NASH to prevent the progression of hepatic fibrosis, resulting in HCC or liver-related mortality without increasing the risk of cardiovascular or renal events. Combination therapies, such as glucagon receptor agonist/GLP-1 or gastrointestinal peptide/GLP-1, are under development. This review focused on antidiabetic agents and future perspectives on the view of the treatment of NAFLD with T2D.

    A fourth of the adult population is now suffering from nonalcoholic fatty liver disease (NAFLD) worldwide. Nonalcoholic steatohepatitis (NASH), a severe form of NAFLD, can lead to liver-related mortality. NAFLD/NASH is closely associated with type 2 diabetes. Although pioglitazone is now recommended as the 1st line therapy for NASH with type 2 diabetes, pioglitazone has several safety concerns such as body weight gain, heart failure, fluid retention, and bone fracture in women. Sodium-glucose cotransporter 2 (SGLT2) inhibitors have a variety of functions such as glycemic control, bodyweight reduction, and decreased body pressure. Accumulating evidence has shown that this agent has also cardioprotective and renoprotective effects in patients with or without type 2 diabetes. Recent studies that SGLT2 inhibitor can also reduce in transaminase activities or hepatic fat content in NAFLD. NAFLD patients with type 2 diabetes can be indicated for SGLT2 inhibitor, because they are obese, have insulin resistance, and at high risk of cardiovascular events. The phase 3 study of dapagliflozin for NAFLD (DEAN study) is now ongoing. It remains unknown whether this agent can ameliorate hepatic fibrosis in NASH, leading to improved over-all or liver-related survival. Since the leading cause of NAFLD mortality is cardiovascular events, SGLT2 inhibitors will become the 1st line treatment for NAFLD/NASH.

    In hepatocellular carcinoma (HCC), the clinical significance of soluble immune checkpoint protein levels as predictors of patient outcomes or therapeutic responses has yet to be defined. This study profiled the baseline levels of sixteen soluble checkpoint proteins and their changes following sorafenib treatment for HCC. Plasma samples were obtained from 53 patients with advanced HCC at baseline, week 1, 2 and 4 of sorafenib treatment and tested the concentrations of 16 soluble checkpoint proteins using multiplexed fluorescent bead-based immunoassays. Multivariate analysis showed high sBTLA levels at baseline were an independent predictor of poor overall survival (p = 0.038). BTLA was highly expressed in T cells and macrophages in peritumoral areas. At week 2, sCD27 levels were decreased compared to baseline. By contrast, the concentrations of most inhibitory proteins, including sBTLA, sLAG-3, sCTLA-4, sPD-1, sCD80, sCD86 and sPD-L1, had significantly increased. The fold-changes of soluble checkpoint receptors and their ligands, including sCTLA-4 with sCD80/sCD86, sPD-1 with sPD-L1; and the fold-changes of sCTLA-4 with sBTLA or sPD-1 were positively correlated. sBTLA may be a good biomarker for predicting overall survival in HCC patients. Sorafenib treatment in patients with advanced HCC revealed dynamic changes of soluble checkpoint protein levels.

Dynamic computed tomography (CT) demonstrated a tumor, 88×73 mm in diameter, which was adherent to the caudate lobe of the liver and pancreas. Based on these findings, we performed a laparotomy with a preoperative diagnosis of hepatocellular carcinoma (HCC) originating from the caudate lobe of the liver. The tumor could be dissected from the liver, however, it had infiltrated into the common hepatic artery, leading to incomplete extirpation of the tumor. Histological examination revealed that the tumor was an ectopic HCC. Lenvatinib mesylate (lenvatinib) was used as systemic therapy for growth of the remnant tumor 16 days after surgery. CT performed during two months after initiating lenvatinib revealed that the tumor size had reduced with a decrease in vascularity, which was deemed to be a partial response. CT performed three months after the initiation of lenvatinib demonstrated regrowth of the tumor. The patient died of HCC 164 days after surgery.</p>

    In Japan, bezafibrate (BF) is a second-line agent for primary biliary cholangitis (PBC) that is refractory to ursodeoxycholic acid (UDCA) treatment. From a retrospective cohort (n = 873) from the Japan PBC Study Group, we enrolled 118 patients who had received UDCA monotherapy for at least 1 year followed by combination therapy with UDCA+BF for at least 1 year. GLOBE and UK-PBC scores after UDCA monotherapy (i.e., immediately before UDCA+BF combination therapy) were compared with those after 1 year of UDCA+BF combination therapy. The real outcomes of enrolled patients estimated by Kaplan-Meier analysis were compared with the predicted outcomes calculated using GLOBE and UK-PBC scores. In addition, the hazard ratio of BF treatment was calculated using propensity score analysis. The mean GLOBE score before the combination therapy was 0.504 ± 0.080, which improved significantly to 0.115 ± 0.085 (P < 0.0001) after 1 year of combination therapy. The real liver transplant-free survival of enrolled patients was significantly better than that predicted by GLOBE score before introducing BF. Combination therapy did not significantly improve the real rates of liver transplantation or liver-related death compared with those predicted by UK-PBC risk score before introducing BF, but the predicted risk was significantly reduced by the addition of BF (P < 0.0001). Cox regression analysis with inverse probability of treatment weighting showed that the addition of BF significantly reduced the hazard of liver transplant or liver-related death in patients who, after 1 year of UDCA monotherapy, had normal serum bilirubin (adjusted hazard ratio 0.09, 95% confidence interval 0.01-0.60, P = 0.013). Conclusion: Addition of BF to UDCA monotherapy improves not only GLOBE and UK-PBC scores but also the long-term prognosis of PBC patients, especially those with early-stage PBC.

    <p>Sarcoidosis is typically characterized by the presence of lesions in the lungs, heart, eyes, and skin. However, in some cases, lesions have also been found in the liver. Although the diagnosis of hepatic sarcoidosis is difficult, liver biopsy can occasionally offer a definite diagnosis when blood test results indicate liver dysfunction of an unknown etiology. We encountered five cases of hepatic sarcoidosis at our hospital that were diagnosed based on liver dysfunction and compared these cases with previously reported cases. In our case series, hepatic sarcoidosis was predominantly diagnosed in middle-aged women, and biliary enzymes were elevated in most cases. Corticosteroids, ursodeoxycholic acid, or both were used for treatment. Despite the application of these therapies, some patients progressed to showing cirrhosis or even died. Thus, in cases with severe hepatitis, steroid therapy may not be effective and cirrhosis may develop. Moreover, the findings suggest that ursodeoxycholic acid can help in delaying the progression of hepatic sarcoidosis.</p>

    Recently, three tyrosine kinase inhibitors (TKIs) have become available for treatment of unresectable hepatocellular carcinoma (HCC). We herein report a case of a 59-year-old man with interstitial pneumonia that was suspected during regorafenib administration and was exacerbated by subsequent lenvatinib treatment for advanced HCC. After sorafenib was discontinued due to progressive HCC, regorafenib treatment was started. Progressive HCC was again noted and reticular shadows were suspected in both lower lung fields at 2 months after starting regorafenib administration. Subsequent treatment with lenvatinib obtained a partial response for HCC, but the reticular shadows became marked and dyspnea on effort emerged, followed by hypoxemia and an increased Krebs von den Lungen-6 (KL-6) value. Because we suspected acute interstitial pneumonia, due to these TKIs, intravenous pulse steroid therapy was started immediately after discontinuing lenvatinib. Within 1 week after starting steroid therapy, the patient's respiratory condition and hypoxemia gradually began improving. No previous case of pulmonary interstitial changes that appeared in association with regorafenib administration for HCC and that were exacerbated by subsequent treatment with lenvatinib has been reported. This case emphasizes that it is necessary to observe the patient's respiratory condition and to perform imaging examinations to monitor for adverse events during TKI treatment.

    Pruritus is a common pathogenesis in liver diseases, including chronic hepatitis B (CHB). The phases of hepatitis B virus (HBV) infection are defined in the American Association for the Study of Liver Diseases guidelines. However, it still remains unclear whether the phase independently affects pruritus. The aim of this study was to clarify the effect of HBV infection phase on pruritus in patients with HBV. Of the 1,631 patients that attended the joint research facilities and were interviewed regarding their pruritus between January and June 2016, 196 patients with HBV infection were selected for the present analysis. One-to-one propensity score-matching using 13 variables was performed between participants in the hepatitis B e antigen (HBe-Ag)-positive/negative immune-active phase group and the inactive CHB phase group. Data from 47 patients per group were included in the final analysis. The prevalence of pruritus in the inactive CHB phase was significantly lower than in the HBe-Ag-positive/negative immune-active phase (23 vs. 47%; P=0.031). Being in the inactive CHB phase was determined to be an independent risk factor for pruritus (odds ratio, 0.35; 95% confidence interval, 0.143-0.842; P=0.019). The progression to inactive CHB phase may contribute to the amelioration of pruritus in patients with HBV infection.

    BACKGROUND AND AIM: Although non-alcoholic fatty liver disease (NAFLD) is common in the general population, identifying patients with advanced fibrosis remains a challenge. We investigated whether the homeostasis model assessment parameter of insulin resistance (HOMA-IR), an index of IR and one of the most important metabolic factors, is an independent predictive factor for advanced fibrosis in nondiabetic patients with NAFLD. METHODS: This was a retrospective, cross-sectional multicenter study. We included 361 patients with biopsy-proven NAFLD who had not been diagnosed with type 2 diabetes mellitus: 175 (48%) were women and 48 (13%) had advanced fibrosis. We used simple random sampling; the sampling ratio of the estimation and validation groups was 7:3. A logistic model was constructed for both the estimation and validation groups. The explanatory variables were age ≥ 49 years, sex (women), body mass index ≥ 26.7 kg/m2 , the presence of hypertension, presence of dyslipidemia, fasting plasma glucose level ≥ 98 mg/dL, fasting immune reactive insulin level ≥ 12.0 μU/mL, and HOMA-IR ≥ 2.90. The median HOMA-IR of the patients was 2.88 (interquartile range: 2.1-4.8). RESULTS: In the estimation group, univariate and multivariate analyses showed that age, dyslipidemia, and HOMA-IR were independent predictors of advanced fibrosis. In the validation group, only age and HOMA-IR were found to be independent predictors of advanced fibrosis. CONCLUSIONS: Homeostasis model assessment parameter of insulin resistance was an independent predictor of advanced liver fibrosis in nondiabetic patients with NAFLD. Given that most patients with NAFLD are nondiabetic, it is important to set goals with respect to improving IR to subsequently reduce liver fibrosis.

We estimated the prevalence, incidence, and outcomes of NAFLD in the Asian population to assist stakeholders in understanding NAFLD disease burden. METHODS: We searched PubMed, EMBASE, and the Cochrane Library from database inception to Jan 17, 2019, for studies reporting NAFLD prevalence, incidence, or outcome in Asia. We included only cross-sectional and longitudinal observational studies of patients with NAFLD diagnosed by imaging, serum-based indices, or liver biopsy. Studies that included patients with overlapping liver disease or that did not screen for excess alcohol consumption were excluded. Two investigators independently screened and extracted data. The main outcomes were pooled NAFLD prevalence, incidence, and hepatocellular carcinoma incidence and overall mortality in patients with NAFLD. Summary estimates were calculated using a random-effects model. This study is registered with PROSPERO, number CRD42018088468. FINDINGS: Of 4995 records identified, 237 studies (13 044 518 participants) were included for analysis. The overall prevalence of NAFLD regardless of diagnostic method was 29·62% (95% CI 28·13-31·15). NAFLD prevalence increased significantly over time (25·28% [22·42-28·37] between 1999 and 2005, 28·46% [26·70-30·29] between 2006 and 2011, and 33·90% [31·74-36·12] between 2012 and 2017; p<0·0001). The pooled annual NAFLD incidence rate was 50·9 cases per 1000 person-years (95% CI 44·8-57·4). In patients with NAFLD, the annual incidence of hepatocellular carcinoma was 1·8 cases per 1000 person-years (0·8-3·1) and overall mortality rate was 5·3 deaths per 1000 person-years (1·5-11·4). INTERPRETATION: NAFLD prevalence in Asia is increasing and is associated with poor outcomes including hepatocellular carcinoma and death. Targeted public health strategies must be developed in Asia to target the drivers of this rising epidemic and its associated complications, especially in high-risk groups, such as older obese men. FUNDING: None.

    <p>Sarcoidosis is typically characterized by the presence of lesions in the lungs, heart, eyes, and skin. However, in some cases, lesions have also been found in the liver. Although the diagnosis of hepatic sarcoidosis is difficult, liver biopsy can occasionally offer a definite diagnosis when blood test results indicate liver dysfunction of an unknown etiology. We encountered five cases of hepatic sarcoidosis at our hospital that were diagnosed based on liver dysfunction and compared these cases with previously reported cases. In our case series, hepatic sarcoidosis was predominantly diagnosed in middle-aged women, and biliary enzymes were elevated in most cases. Corticosteroids, ursodeoxycholic acid, or both were used for treatment. Despite the application of these therapies, some patients progressed to showing cirrhosis or even died. Thus, in cases with severe hepatitis, steroid therapy may not be effective and cirrhosis may develop. Moreover, the findings suggest that ursodeoxycholic acid can help in delaying the progression of hepatic sarcoidosis.</p>

    Background: Interferon-free, direct-acting antiviral treatments can result in a sustained virologic response in nearly 100% of patients with chronic hepatitis C virus infection. Aims: The purpose of this study was to evaluate histological improvement after achieving a sustained virologic response to direct-acting antiviral treatments in patients with chronic hepatitis C. Methods: Among 691 patients with chronic hepatitis C who achieved a sustained virologic response to direct-acting antivirals, 51 underwent liver biopsy 41 ± 20 weeks after the end of treatment despite normal transaminase levels. In 20 patients, liver biopsy specimens obtained a median of 1.2 years before the start of treatment were available. Results: Among the 51 patients who underwent post-sustained virologic response biopsies, the grade of inflammation was A0 in 18 patients, A1 in 24, A2 in eight, and A3 in one; the stage of fibrosis was F0 in three patients, F1 in 20, F2 in 15, F3 in nine, and F4 in four. Among the nine post-sustained virologic response biopsy specimens with moderate-to-severe inflammation (≥A2), four showed S1-to-S3 steatosis (>5% of hepatocytes affected). In the 20 paired biopsy specimens, the inflammation grade significantly regressed (p = 0.0043), but the fibrosis stage did not (p = 0.45). Histological improvement, defined as a ≥ 2-point decrease in the Knodell inflammatory score and no worsening of the fibrosis, was found in 11 (55%) patients. The iron accumulation had significantly regressed (p = 0.0093), but the steatosis had not (p = 0.10). Conclusions: Even if transaminases become normal after obtaining a sustained virologic response, significant histological inflammation of unknown cause was found in some patients. Additionally, improvement in liver fibrosis was not evident in the short term.

    Background: The FIB4 index is clinically useful, but because its formula includes age, the appropriate cutoff point may differ by age group. Here, new FIB4 index cutoff points were validated using cohort data from 14 hepatology centers in Japan. Methods: The FIB4 index was determined in biopsy-confirmed NAFLD patients (n = 1050) who were divided into four groups: ≤ 49, 50–59, 60–69, and ≥ 70 years. ROC analysis predicted advanced fibrosis in each age group
    low and high cutoff points were defined by a sensitivity and specificity of 90%. The new and conventional cutoffs were compared for detecting advanced fibrosis. Results: The modified low and high cutoff points were 1.05 and 1.21 in ≤ 49 years, 1.24 and 1.96 in 50–59 years, 1.88 and 3.24 in 60–69 years, and 1.95 and 4.56 in ≥ 70 years. In ≥ 60 years, the false-negative rate was increased using the modified high cutoff point, and the high cutoff point was better with the conventional cutoff point. The new proposed low and high cutoff points are 1.05 and 1.21 in ≤ 49 years, 1.24 and 1.96 in 50–59 years, 1.88 and 2.67 in 60–69 years, and 1.95 and 2.67 in ≥ 70 years
    these cutoff points improved the accuracy of advanced fibrosis diagnosis. Conclusions: FIB4 index cutoff points for predicting advanced fibrosis in NAFLD increased with age. Cutoff points modified by age improved the diagnostic accuracy of estimations of advanced liver fibrosis using the FIB4 index.

    The prognosis of patients with nonalcoholic fatty liver disease-related hepatocellular carcinoma (NAFLD-HCC) is intricately associated with various factors. We aimed to investigate the prognostic algorithm of NAFLD-HCC patients using a data-mining analysis. A total of 247 NAFLD-HCC patients diagnosed from 2000 to 2014 were registered from 17 medical institutions in Japan. Of these, 136 patients remained alive (Alive group) and 111 patients had died at the censor time point (Deceased group). The random forest analysis demonstrated that treatment for HCC and the serum albumin level were the first and second distinguishing factors between the Alive and Deceased groups. A decision-tree algorithm revealed that the best profile comprised treatment with hepatectomy or radiofrequency ablation and a serum albumin level ≥3.7 g/dL (Group 1). The second-best profile comprised treatment with hepatectomy or radiofrequency ablation and serum albumin levels <3.7 g/dL (Group 2). The 5-year overall survival rate was significantly higher in the Group 1 than in the Group 2. Thus, we demonstrated that curative treatment for HCC and serum albumin level >3.7 g/dL was the best prognostic profile for NAFLD-HCC patients. This novel prognostic algorithm for patients with NAFLD-HCC could be used for clinical management.

    Aim: The optimal combination of two currently available agents with different mechanisms of action, a nucleos(t)ide analog and pegylated interferon-α (PegIFNα), must be determined to improve treatment of chronic hepatitis B (CHB). Methods: In this study, 24 patients with CHB (14 hepatitis B envelope antigen [HBeAg]-positive patients and 10 HBeAg-negative patients) received entecavir for 36–52 weeks, followed by entecavir plus Peg-IFNα2a for 4 weeks, and finally by PegIFNα-2a alone for 44 weeks. Results: A sustained biochemical, virologic, and serologic response was obtained in 7/24 (29%) patients at 48 weeks post-treatment (2/14 [14%] in HBeAg-positive vs 5/10 [50%] in HBeAg-negative patients, P = 0.085). At baseline, patients with a sustained response had a significantly lower γ-glutamyl transferase level (P = 0.0023), a lower aspartate aminotransferase-to-platelet ratio index (P = 0.049), and a lower α-fetoprotein level (P = 0.042) than those without a sustained response. The decline in hepatitis B surface antigen (HBsAg) levels during the first 24 weeks of PegIFNα-2a treatment in patients with a sustained response was greater than that in patients without (P = 0.017). Additionally, HBsAg seroclearance was achieved in two patients (8.3%): one HBeAg-positive and one HBeAg-negative patient. Conclusion: The outcomes of sequential therapy involving an early switch from entecavir to PegIFNα-2a were unsatisfactory in Japanese patients with CHB. In addition to viral factors, host metabolic characteristics and liver fibrosis/tumor markers can be used for prediction of a sustained response to therapy, but accurate prediction of the therapeutic response is difficult.

    It is unclear whether multiple nonstructural (NS) 5A resistance-associated substitutions (RASs) correlate with the outcome of sofosbuvir (SOF) and ledipasvir (LDV) therapy. We investigated the effects of multiple NS5A RASs in NS5A inhibitor-naïve patients with chronic hepatitis C virus genotype 1b infection treated with SOF/LDV. In 313 patients treated with SOF/LDV, we assessed the effects of multiple NS5A RASs on the sustained virological response (SVR). RASs at L28, R30, L31, Q54, P58, Q62, A92, and Y93 in the NS5A region were examined by direct sequencing. The prevalence of RASs was as follows: 2.6% at L28, 8.7% at R30, 6.1% at L31, 48.7% at Q54, 9.9% at P58, 9.9% at Q62, 5.1% at A92, 13.8% at Y93, and 19.2% at L31 or Y93. A total of 133 patients had no RASs. SVR was achieved in 98.7% of the patients. SVR rates significantly differed between patients with and without the L31 or Y93 RAS (93.0% [53/57] vs 100% [250/250], P =.0011). In addition, among patients with the L31 or Y93 RAS, 29.8%, 45.6% and 24.6% had one, two and three or more NS5A RASs, respectively. The SVR rate was significantly lower in patients with the L31 or Y93 RAS with more than three NS5A RASs compared to those with fewer than three NS5A RASs (71.4% [10/14] vs 100% [43/43], P =.0025). Although the prevalence of multiple NS5A RASs at baseline was low in NS5A inhibitor-naïve patients, the presence of multiple NS5A RASs was associated with the effectiveness of SOF/LDV therapy.

    In contrast to patients with viral hepatitis, patients with nonalcoholic fatty liver disease (NAFLD) can progress to hepatocellular carcinoma during the initial stages of liver fibrosis. Development and implementation of noninvasive methods for diagnosis and progression prediction are important for effective NAFLD surveillance. Mac-2 binding protein (Mac-2bp) is a useful nonalcoholic steatohepatitis (NASH) diagnosis biomarker and a powerful prediction biomarker for NAFLD fibrosis stage. Wisteria floribunda agglutinin (WFA)-positive Mac-2bp (WFA+-M2BP) is a novel serum fibrosis biomarker for chronic hepatitis C that has clinical validity. Mac-2bp and WFA+-M2BP are also clinical NAFLD biomarker candidates. We examined the efficacy of Mac-2bp and WFA+-M2BP for NAFLD assessment using patients with biopsy-proven NAFLD (n = 510; NAFLD cohort) and subjects who received a health check-up (n = 2,122; check-up cohort). In the NAFLD cohort, we set the fibrosis predicting cutoff values as 1.80 (F1), 2.21 (F2), and 2.24 μg/mL (F3). In the subjects with fatty liver from the check-up cohort (n = 1,291), the serum Mac-2bp levels were >1.80 μg/mL in 38.6% of the subjects (n = 498), and >2.24 μg/mL in 24.6% of the subjects (n = 318). The NAFLD cohort results indicated that Mac-2bp and WFA+-M2BP were equally useful for NASH diagnosis. During the early stages of fibrosis (F1, F2), the increase in Mac-2bp was statistically significant but WFA+-M2BP did not increase. Logistic regression analysis revealed that Mac-2bp was an independent determinant for the prediction of advanced fibrosis stage (≥F2), even when adjusted for WFA+-M2BP. Immunohistochemical staining of Mac-2bp revealed that hepatocytes strongly expressed Mac-2bp in patients with NAFLD. Conclusion: Our results indicated that hepatocyte-derived Mac-2bp would be a useful single biomarker for NASH diagnosis and fibrosis stage prediction in patients with NAFLD.

    To uncover mechanisms of nonalcoholic steatohepatitis (NASH) associated hepatocarcinogenesis, we compared the proteomes of human NASH-associated liver biopsies, resected hepatocellular carcinomas (HCCs) and HCCs of HCV+ patients with normal liver tissue of patients with gastrointestinal tumor metastasis, in formalin-fixed paraffin-embedded samples obtained after surgery in our hospital during the period from 2006 to 2011. In addition, proteome analysis of liver tumors in male STAM NASH-model mice was performed. Similar changes in the proteome spectrum such as overexpression of enzymes involved in lipid, cholesterol and bile acid biosynthesis and examples associated with suppression of fatty acid oxidation and catabolism, alcohol metabolism, mitochondrial function as well as low expression levels of cytokeratins 8 and 18 were observed in both human NASH biopsies and NASH HCCs, but not HCV+ HCCs. Alterations in downstream protein expression pointed to significant activation of transforming growth factor , SMAD family member 3, -catenin, Nrf2, SREBP-LXR and nuclear receptor-interacting protein 1 (NRIP1), and inhibition of PPARs and p53 in human NASH biopsies and/or HCCs, suggesting their involvement in accumulation of lipids, development of fibrosis, oxidative stress, cell proliferation and suppression of apoptosis in NASH hepatocarcinogenesis. In STAM mice, PPARs inhibition was not obvious, while expression of cytokeratins 8 and 18 was elevated, indicative of essential differences between human and mouse NASH pathogenesis.

    世界保健機構(WHO)が開発した過剰飲酒を短時間で評価するための10項目の質問文からなる「アルコール使用障害特定テスト」(The Alcohol Use Disorders Identification Test;AUDIT)の、飲酒量の推定における有用性を検討することを目的に、2014年6月〜2015年3月に当院の内科外来に通院した患者334名(男性174名、女性160名)を対象に、飲酒量を正確に推定するため電子カルテ上に飲酒頻度(日、週、月)、種類(ビール、ワイン、ウイスキー等)、量(コップ、グラス等)から1日当たりの摂取エタノール量(g/日)を自動計算するテンプレート(Juso Alcohol Calculator;JAC)を作成し、これにより推定された飲酒量と、同じ患者にAUDITを施行して得られたスコアの相関を検討した。その結果、JACによる1日当たりの摂取エタノールとAUDITスコアの間に高い相関が認められた。また、10分割交差法を用いたhazardous drinking(飲酒者や他者に対する有害事象のリスクが上昇するアルコール摂取パターン、56名(16%)が該当)におけるAUDITスコアの至適カットオフ値は8.2点で、男性10.0点、女性6.1点と、男女差を認めた。

    It is important to screen for alcohol consumption and drinking customs by using a stan- dardized method. The aim of this study was to investigate whether standardized questionnaire was useful for predicting alcohol consumption. A cross-sectional study using the Alcohol Use Disorders Identification Test (AUDIT) was conducted in 334 outpatients who consulted the Internal Medicine Department of Osaka City Juso Hospital. The patients completed self-reported questionnaires and underwent a diagnostic interview, physical examination, and laboratory testing. Forty (23%) male patients reported daily alcohol consumption 40 g, and 16 (10%) female patients reported consumption 20 g. The optimal cutoff values of hazardous drinking (all patients)/ drinker (male)/ drinker (female) were calculated using a 10-fold cross validation, resulting in an optimal AUDIT score cutoff of 8.2/ 7.2/ 6.1, with sensitivity of 95.5%/ 96.3%/ 88.9%, specificity of 87.0%/ 96.3%/ 88.9%, false positive rate of 13.0%/ 9.4%/6.6%, false negative rate of 4.5%/ 3.'%/ 11.1%, and area under the receiver operating characteristic curve of 0.97/ 0.98/ 0.99. In conclusion, this study showed that the AUDIT score was useful for predicting alcohol consumption.

    Background: Currently, no system for appropriate intra-hospital collaboration regarding hepatitis virus positive individuals exists, even in medical institutions with hepatologists among their staff. The main objective of this study was to explore a simple alert system to promote the referral of patients with hepatitis B surface antigen (HBsAg)- or anti-hepatitis C virus (HCV) antibodies positivity to hepatologists through electronic medical records.
    Methods: Since April 2014 at Osaka City Juso Hospital, "sticky notes" have been put on the electronic medical records of patients newly diagnosed with HBsAg- or anti-HCV- antibodies positivity to recommend intra-hospital referral of those patients to specialists. In this study, we investigated the number of referrals to hepatologists before vs. after the introduction of this system (that is, in fiscal years 2013 [Period 1] and 2014 [Period 2], respectively), and the subsequent clinical courses of the patients.
    Results: The proportions of patients with HBsAg and anti-HCV antibody positivity did not show statistically significant differences between Period 1 and Period 2 (1.6 % [43/2,757] vs. 1.3 % [39/2,891], p = 0.58; and 5.8 % [156/2,674] vs. 5.3 % [147/2,790], p = 0.39, respectively). However, the referral proportions for patients with HBsAg- and anti-HCV antibody positivity were significantly higher in Period 2 (73 % [11/15] and 65 % [41/63], respectively) than in Period 1 (28 % [5/18] and 17 % [9/54]) (p = 0.009 and p &lt; 0.001, respectively). Among patients who were referred to hepatologists, 2 HBsAg- positive and 4 anti-HCV antibody positive patients initiated antiviral treatment.
    Conclusion: Our simple electronic medical record based alert system effectively promoted intra-hospital referral of hepatitis virus-positive patients, who have been detected by screening tests, to hepatologists.

    In Japan, the prevalence of hepatocellular carcinoma (HCC) associated with nonviral liver disease, especially with nonalcoholic fatty liver disease (NAFLD-HCC) and alcoholic liver disease (ALD-HCC), has been increasing. Clarification of the clinical features of NAFLD-HCC and ALD-HCC is needed. We performed a large retrospective multicenter survey to clarify the clinical course of these two types of HCC.
    Clinical characteristics, survival, and recurrence were examined in 532 patients with ALD-HCC and 209 patients with NAFLD-HCC who were diagnosed between January 2000 and December 2013.
    The ALD-HCC patients were predominantly male and were younger than the patients with NAFLD-HCC. Lifestyle-related diseases were significantly more common in the NAFLD-HCC group, but the prevalence of cirrhosis was significantly higher in the ALD-HCC group. The histological diagnosis of NAFLD-HCC showed a gender difference (F4; 72.7 % in the females vs. 37.6 % in the males). The characteristic features of HCC including histology, survival rate, and recurrence rate were quite similar in the NAFLD-HCC and ALD-HCC groups: 5-year survival rates 49.1 vs. 43.7 %; 5-year recurrence rates 69.6 vs. 65.4 %, respectively. However, the risk factors for recurrence differed between the two groups: des-gamma-carboxy prothrombin was a risk factor in NAFLD-HCC and alpha-fetoprotein was a risk factor in ALD-HCC.
    Although the characteristic features underlying these two diseases are different, the two HCC groups showed a similar clinical course. The recurrence rates of the two HCC groups were relatively high. We found that critical tumor markers for recurrence differed between the two diseases.

    Background: It is important to screen for alcohol consumption and drinking customs in a standardized manner. The aim of this study was 1) to investigate whether the AUDIT score is useful for predicting hazardous drinking using optimal cutoff scores and 2) to use multivariate analysis to evaluate whether the AUDIT score was more useful than pre-existing laboratory tests for predicting hazardous drinking.
    Methods: A cross-sectional study using the Alcohol Use Disorders Identification Test (AUDIT) was conducted in 334 outpatients who consulted our internal medicine department. The patients completed self-reported questionnaires and underwent a diagnostic interview, physical examination, and laboratory testing.
    Results: Forty (23 %) male patients reported daily alcohol consumption &gt;= 40 g, and 16 (10 %) female patients reported consumption &gt;= 20 g. The optimal cutoff values of hazardous drinking were calculated using a 10-fold cross validation, resulting in an optimal AUDIT score cutoff of 8.2, with a sensitivity of 95.5 %, specificity of 87.0 %, false positive rate of 13.0 %, false negative rate of 4.5 %, and area under the receiver operating characteristic curve of 0.97. Multivariate analysis revealed that the most popular short version of the AUDIT consisting solely of its three consumption items (AUDIT-C) and patient sex were significantly associated with hazardous drinking. The aspartate transaminase (AST)/alanine transaminase (ALT) ratio and mean corpuscular volume (MCV) were weakly significant.
    Conclusions: This study showed that the AUDIT score and particularly the AUDIT-C score were more useful than the AST/ALT ratio and MCV for predicting hazardous drinking.

    最近の13年間に便毒素検査や便培養により,Clostridium difficile感染症(CDI)と診断され,大腸内視鏡検査を施行した39例について後方視的に内視鏡像,臨床像,診断方法,治療などについて検討した.CDIは内視鏡像から偽膜型,アフタ型,非特異型,正常型に分類することが可能であり,それぞれの割合は,36%,28%,15%,20%であった.臨床像と炎症反応の検討により,偽膜型はCDIの重症型であり,他の3型は軽症型であると考えられた.内視鏡像の検討より,アフタは偽膜の初期像の可能性が高いと推察された.また,非偽膜型の内視鏡像からもCDIを疑うことはある程度可能であると考えられた.CDIの診断はまずCD抗原とCD毒素の検査を行うことで迅速に判定を行う.それにCD培養,内視鏡検査などを組み合わせることで効率的で確実な診断が可能となる.偽膜型では薬物投与が必須であるが,それ以外では抗菌薬の中止のみで軽快する症例がみられる.(著者抄録)

    It remains unclear whether intra-hospital collaboration regarding hepatitis B and C virus carriers identified by infection screening testing occurs appropriately in non-hepatology departments. Our hospital developed an alert system in April 2013 to promote referral of hepatitis B surface antigen (HBsAg)-positive or anti-heptitic C virus (HCV)-positive patients to the Department of Hepatology through electronic medical records. Since the introduction of the new system, the number of intra-hospital referrals regarding hepatitis virus infections increased from 18.8±5.7 to 29.0±4.5 per month. A steady stream of referrals originated from departments in which there were more patients who tested positive for the hepatitis virus. This alert system is useful for promoting the intra-hospital referral of hepatitis virus carriers who are detected by screening tests to hepatology specialists and is thus considered to be important in the appropriate management of chronic viral hepatitis.

    Nonalcoholic fatty liver disease (NAFLD) is a growing medical problem; thus, discriminating nonalcoholic steatohepatitis (NASH) from NAFLD is of great clinical significance. For the diagnosis of NASH, liver biopsy-proven histological examination is the current gold standard, and noninvasive and reliable biomarkers are greatly needed. Recently, we found that two glycobiomarkers, fucosylated haptoglobin (Fuc-Hpt) and Mac-2 binding protein (Mac2bp), are useful independently for NASH diagnosis. In this study, we confirmed that serum Fuc-Hpt is suitable for the prediction of ballooning hepatocytes and that serum Mac2bp is suitable for the prediction of liver fibrosis severity in 124 biopsy-proven NAFLD patients (training cohort). In addition, we found that the combination of serum Fuc-Hpt and Mac2bp levels was an excellent tool for NASH diagnosis. Using receiver operating characteristic analyses, the area under the receiver operating characteristic curve, sensitivity, and specificity of the combination of these two glycobiomarkers were 0.854, 81.1%, and 79.3%, respectively. We established a prediction model for NASH diagnosis using logistic regression analysis: logit (p)=-2.700+0.00242 x Fuc-Hpt+1.225 x Mac2bp. To validate the prediction model, another 382 biopsy-proven NAFLD patients were enrolled (validation cohort). In the validation cohort, the area under the receiver operating characteristic curve of this model for NASH diagnosis was 0.844, with 71.4% and 82.3% sensitivity and specificity, respectively. In addition, we investigated the significance of our developed NASH diagnosis model in ultrasound-diagnosed NAFLD subjects who received medical health checkups (n=803). Our model also could predict NAFLD disease severity in this larger population. Conclusion: The combination of serum Fuc-Hpt and Mac2bp can distinguish NASH from NAFLD patients. Our noninvasive model using two serum glycobiomarkers contributes to a novel NASH diagnostic methodology that could replace liver biopsy. (Hepatology 2015;62:1433-1443)

    This study was conducted to clarify the role of cytoglobin (Cygb), a globin expressed in hepatic stellate cells (HSCs), in the development of Liver fibrosis and cancer in nonalcoholic steatohepatitis (NASH). Cygb expression was assessed in patients with NASH and hepatocellular carcinoma. Mouse NASH model was generated in Cygb-deficient (Cygb(-/-)) or wild-type (WT) mice by giving a choline-deficient amino acid defined diet and, in some of them, macrophage deletion and N-acetyl cysteine treatment were used. Primary-cultured mouse HSCs isolated from WT (HSCsCygb-wild) or Cygb(-/-) (HSCsCygb-null) mice were characterized. As results, the expression of CYGB was reduced in patients with NASH and hepatocellular carcinoma. Choline-deficient amino acid treatment for 8 weeks induced prominent inflammation and fibrosis in Cygb(-/-) mice, which was inhibited by macrophage deletion. Surprisingly, at 32 weeks, despite no tumor formation in the WT mice, all Cygb(-/-) mice developed liver cancer, which was ameliorated by N-acetyl cysteine treatment. Altered expression of 31 genes involved in the metabolism of reactive oxygen species was notable in Cygb(-/-) mice. Both HSCsCygb-null and Cygb siRNA-transfected-HSCsCYgb-wild exhibited the preactivation condition. Our findings provide important insights into the role that Cygb, expressed in HSCs during liver fibrosis, plays in cancer development with NASH.

    Aim. Anemia is the most common adverse event in patients with chronic hepatitis C virus (HCV) treated with telaprevir (TVR) combined triple therapy. We examined the effects of drug dose adjustment on anemia and a sustained viral response (SVR) during combination therapy. Material and methods. This study enrolled 62 patients treated with TVR (2,250 mg) for 12 weeks plus pegylated interferon-alpha-2b and ribavirin for 24 weeks. The patients were assigned randomly to the TVR-standard or -reduced groups before treatment. At the occurrence of anemia (hemoglobin &lt; 12 g/dL), the TVR-reduced group received 1500 mg TVR plus the standard dose of ribavirin, whereas the TVR-standard group received the standard TVR dose (2,250 mg) and a reduced dose of ribavirin (200 mg lower than prescribed originally). The safety and SVR at 24 weeks were compared between the TVR-standard (n = 28) and TVR-reduced (n = 25) groups. Results. No differences in the proportion of patients who became HCV RNA-negative were detected between the TVR-standard and -reduced groups (72 and 72% at week 4, 79 and 84% at the end of treatment, and 76 and 80% at SVR24, respectively). Two groups had comparable numbers of adverse events, which led to the discontinuation of TVR in 14 patients of TVR-standard group and in 14 of TVR-reduced group. A lower incidence of renal impairment was observed in the TVR-reduced group (6%) than the TVR-standard group (11%, not statistically significant). Conclusions. TVR dose adjustment could prevent anemia progression without weakening the anti-viral effect during triple therapy in HCV-patients.

    Serum ferritin was recently reported to have low diagnostic accuracy for the detection of advanced fibrosis in patients with non-alcoholic fatty liver disease (NAFLD). To corroborate these findings, we investigated the diagnostic accuracy of serum ferritin levels for detecting liver fibrosis in NAFLD patients utilizing a large Japanese cohort database. A total 1201 biopsy-proven NAFLD patients, seen between 2001 and 2013, were enrolled into the Japan Study Group of NAFLD. Analysis was performed on data from this cohort comparing between serum ferritin levels and hepatic histology. Serum ferritin increased with increasing histological grade of steatosis, lobular inflammation and ballooning. Multivariate analyses revealed that sex differences, steatotic grade and fibrotic stage were independently associated with serum ferritin levels (P&lt;0.0001, &lt;0.0001, 0.0248, respectively). However, statistical analyses performed using serum ferritin levels demonstrated that the area under the receiver-operator curve for detecting fibrosis was not adequate for rigorous prediction. Several factors including sex differences, steatosis and fibrosis were found to correlate with serum ferritin levels. Therefore, serum ferritin may have low diagnostic accuracy for specifically detecting liver fibrosis in NAFLD patients due to the involvement of multiple hepatocellular processes.

    Aim: Serum alanine aminotransferase (ALT) is important for screening, diagnosis and management of chronic liver diseases. The incidence of non-alcoholic fatty liver disease (NAFLD)/non-alcoholic steatohepatitis (NASH), which is considered a hepatic manifestation of lifestyle-related diseases, is increasing worldwide. However, the upper limit of the normal ALT level has not yet been established because of not excluding many lifestyle-related diseases. The aim of this study was to evaluate the upper limit of normal serum ALT levels in Japanese subjects. Methods: We analyzed the serum ALT levels of 11 404 Japanese subjects negative for hepatitis B surface antigen and hepatitis C virus antibody, and who received health checkups. Lifestyle factors related to ALT levels were determined by multivariate analysis. Subjects with all factors identified by multivariate analysis within the normal range were defined as "healthy" subjects. The 90th percentile of ALT levels in healthy subjects was defined as the upper limit of normal ALT. Results: Whereas alcohol intake was not a significant factor, the following were independently associated with ALT concentration by multivariate analysis: sex
    age
    body mass index
    waist circumference
    concentrations of total cholesterol, high-density lipoprotein cholesterol, triglycerides and fasting blood glucose
    and fatty liver on ultrasonography. Healthy subjects consisted of 1462 (21.2%) men and 2046 (45.4%) women, and the 90th percentiles of the ALT levels in the two groups were 29 and 23 IU/L, respectively. Conclusion: The upper limits of normal ALT when considering lifestyle factors in Japanese subjects were 29 IU/L in men and 23 IU/L in women.

    The prevalence of nonalcoholic fatty liver disease (NAFLD) and metabolic syndrome have been increasing worldwide. The associations between metabolic factors and the histologic severity of NAFLD have not yet been clarified. Therefore, we studied the relationships between relevant metabolic factors and the histological severity of NAFLD.
    In a cross-sectional multicenter study conducted in Japan, we examined 1,365 biopsy-proven NAFLD patients. The frequencies of underlying lifestyle-related diseases and their relationships to the NAFLD histology were investigated.
    The hepatic fibrosis stages (Stage 0/1/2/3/4) were 22.6/34.1/26.7/14.5/2.1 (%) in the male patients, and 16.2/31.7/23.9/21.6/6.6 (%) in the female patients. Dyslipidemia was present in 65.7 % (hypertriglyceridemia, 45.3 %; increased low-density lipoprotein cholesterol, 37.5 %; decreased high density lipoprotein cholesterol, 19.5 %) of patients. Hypertension was present in 30.2 %, and diabetes mellitus (DM) in 47.3 %. The fibrosis stage increased with age, especially in postmenopausal females. The body mass index was positively correlated with the fibrosis stage. Deterioration of glucose control was positively correlated with the fibrosis stage, this correlation being more prominent in females. Multivariate analysis identified age and DM as significant risk factors for advanced fibrosis. No significant correlation of the fibrosis stage was observed with hypertension. There was a negative correlation between the serum triglyceride levels and the fibrosis stage.
    DM appeared to be a significant risk factor for advanced fibrosis in patients with NAFLD, and would therefore need to be properly managed to prevent the progression of NAFLD.

    Background and Aim: F-18-fluorodeoxyglucose (FDG)-positron emission tomography (PET) may detect primary lesions (PLs) and extrahepatic metastases (EHMs) only in advanced hepatocellular carcinoma (HCC) patients. We investigated the requirement of PET and the optimal timing of PET scanning for accurate staging and treatment planning.
    Methods: We conducted a retrospective investigation of 64 HCC patients who underwent PET (median age, 74 years; male/female, 41/23; etiology, 46 hepatitis C virus/4 hepatitis B virus/4 alcoholic/10 others). To determine the best timing for PET examinations, we analyzed PET result-based recommended treatment changes and characteristics of patients with FDG-avid PLs or EHMs.
    Results: FDG-avid PLs were detected by PET in 22 patients (34%): 18 with hypervascular PL, 11 with serum alpha-fetoprotein levels &gt;= 200 ng/mL, and 11 beyond Milan criteria. EHMs were detected in 21 patients (33%: lymph nodes, 8; lung, 5; abdominal wall, 4; bone, 3; other organs, 4 [including overlapping]). Recommended treatments changed for 16 patients (25%) because of Barcelona Clinic Liver Cancer stage increases based on PET scanning. In multivariate analyses, serum alpha-fetoprotein levels &gt;= 200 ng/mL and beyond Milan criteria were independent factors for FDG-avid PLs and a maximum standardized uptake value (SUVmax) of PLs of (&gt;=) 4.0 was an independent factor for FDG-avid EHMs (P = 0.002, 0.008, and 0.045, respectively).
    Conclusions: PET allows detection of HCC spread in patients with elevated serum a-fetoprotein levels or those beyond Milan criteria and detects EHMs in patients with PLs with high SUVmax values. Optimally timed PET scans can complement conventional imaging for accurate staging and treatment strategy determination.

    Background and Aim: To elucidate the clinical characteristics of hepatitis B virus reactivation (HBV-R), we performed a prospective long-term study of patients with hematologic malignancy, including both hepatitis B virus (HBV) carriers and those with resolved HBV infection.
    Methods: Twenty-one patients with hematopoietic stem-cell transplants (HSCT) and 36 patients given rituximab-based chemotherapy were enrolled. Entecavir was administered prophylactically to eight patients with HBV surface antigen (HBsAg). HBV-DNA was measured every month in 49 patients with resolved HBV infection, and preemptive therapy was given to eight patients with HBV-R.
    Results: HBV-R developed in five (26%) of 19 patients with HSCT and three (10%) of 30 patients given rituximab-based chemotherapy. HBV-R occurred a median of 3 months (range: 2-10) after the end of rituximab-based chemotherapy and 22 months (range: 9-36) after HSCT. HBV-R did not develop in patients with an antibodies against HBsAg (anti-HBs) titer exceeding 200 mIU/mL at baseline. Mutations in the "a" determinant region with amino acid replacement were detected in four of the eight patients with HBV-R. Preemptive therapy prevented severe hepatitis related to HBV-R. Entecavir treatment was stopped in four patients with HBV-R. Since the withdrawal of entecavir, HBV-DNA has not been detected in two patients persistently positive for anti-HBs. No patient had fatal hepatitis.
    Conclusions: Proper management of patients with HBsAg or resolved HBV infection prevented fatal hepatitis related to HBV-R in patients who received immunosuppressive or cytotoxic therapy. Entecavir could be safely discontinued in patients with HBV-R who had acquired anti-HBs.

    AIM: To investigate a simple noninvasive scoring system for predicting liver cirrhosis in nonalcoholic fatty liver disease (NAFLD) patients.
    METHODS: A total of 1048 patients with liver-biopsy-confirmed NAFLD were enrolled from nine hepatology centers in Japan (stage 0, 216; stage 1, 334; stage 2, 270; stage 3, 190; stage 4, 38). The weight and height of the patients were measured using a calibrated scale after requesting the patients to remove their shoes and any heavy clothing. Venous blood samples were obtained in the morning after the patients had fasted overnight for 12 h. Laboratory evaluation was performed in all patients. Statistical analysis was conducted using SPSS version 12.0. Continuous variables were expressed as mean +/- SD.
    RESULTS: The optimal cutoff value of platelet count, serum albumin, and amino-transferase/alanine aminotransferase ratio (AAR) was set at &lt; 15.3 10(4)/mu L, &lt; 4.0 g/dL, and &gt; 0.9, respectively, by the receiver operating characteristic curve. These three variables were combined in an unweighted sum (platelet count = 1 point, serum albumin = 1 point, AAR = 1 point) to form an easily calculated composite score for predicting cirrhosis in NAFLD patients, called the PLALA (platelet, albumin, AAR) score. The diagnosis of PLALA &gt;= 2 had sufficient accuracy for detecting liver cirrhosis in NAFLD patients.
    CONCLUSION: The PLALA score may be an ideal scoring system for detecting cirrhosis in NAFLD patients with sufficient accuracy and simplicity to be considered for clinical use. (C) 2014 Baishideng Publishing Group Inc. All rights reserved.

    Alcoholic liver disease (ALD) is a major cause of morbidity and mortality worldwide. In developed countries, ALD is a major cause of end-stage liver disease that requires transplantation. The spectrum of ALD includes simple steatosis, alcoholic hepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma. Alcohol abstinence is the most effective therapy for ALD. However, targeted therapies are urgently needed for patients with severe ALD (i.e., alcoholic hepatitis) or those who do not abstain from alcohol. The lack of studies and the availability of animal models that do not reflect all the features of this disease in humans inhibit the development of new drugs for ALD. In ALD-associated fibrosis, hepatic stellate cells are the principal cell type responsible for extracellular matrix production. Although the mechanisms underlying fibrosis in ALD are largely similar to those observed in other chronic liver diseases, oxidative stress, methionine metabolism abnormalities, hepatocyte apoptosis, and endotoxin lipopolysaccharides that activate Kupffer cells may play unique roles in disease-related fibrogenesis. Lipogenesis during the early stages of ALD has recently been implicated as a risk factor for the progression of cirrhosis. Other topics include osteopontin, interleukin-1 signaling, and genetic polymorphism. In this review, we discuss the basic pathogenesis of ALD and focus on liver fibrogenesis.

    It is suggested that nonalcoholic fatty liver disease (NAFLD), including nonalcoholic fatty liver (NAFL) and nonalcoholic steatohepatitis (NASH), can be associated with insomnia and gastro-esophageal reflux disease (GERD). The relationship between GERD and insomnia in subjects with biopsy-proven NAFLD was investigated.
    This study enrolled 123 patients with biopsy-proven NAFLD. Insomnia was assessed by the Athens Insomnia Scale (AIS), a self-assessment psychometric instrument designed to quantify sleep difficulty based on ICD-10 criteria; AIS scores a parts per thousand yen 6 were considered positive for insomnia. GERD symptoms were evaluated using a frequency scale for the symptoms of GERD (FSSG); FSSG scores a parts per thousand yen 8 were considered positive. Logistic regression models were used to evaluate the association of insomnia with GERD, after adjusting for potential confounders. Thirteen patients with GERD were treated with the proton pump inhibitor rabeprazole (RPZ; 10 mg/day), for 12 weeks.
    Of the 123 patients, 76 (62 %) were female and 87 (71 %) were obese, with 34 (28 %) having AIS scores a parts per thousand yen 6 and 31 (25 %) having FSSG scores a parts per thousand yen 8. Liver biopsy revealed that 40 patients (33 %) had NAFL and 83 (67 %) had NASH. FSSG and AIS scores were similar in the two groups. HOMA-IR, FSSG scores and gamma GT (GGT) concentrations were significantly higher in insomniacs than in non-insomniacs. Logistic regression analysis demonstrated that FSSG score and GGT concentration were independently associated with insomnia. RPZ treatment resulted in significantly reductions in both AIS and FSSG scores.
    Nearly 30 % of patients with biopsy-proven NAFLD had insomnia, which was related to GGT and GERD and could be relieved by RPZ treatment.

    Cytoglobin (CYGB) is ubiquitously expressed in the cytoplasm of fibroblastic cells in many organs, including hepatic stellate cells. As yet, there is no specific marker with which to distinguish stellate cells from myofibroblasts in the human liver. To investigate whether CYGB can be utilized to distinguish hepatic stellate cells from myofibroblasts in normal and fibrotic human liver, human liver tissues damaged by infection with hepatitis C virus (HCV) and at different stages of fibrosis were obtained by liver biopsy. Immunohistochemistry was performed on histological sections of liver tissues using antibodies against CYGB, cellular retinol-binding protein-1 (CRBP-1), alpha-smooth muscle actin (alpha-SMA), thymocyte differentiation antigen 1 (Thy-1), and fibulin-2 (FBLN2). CYGB- and CRBP-1-positive cells were counted around fibrotic portal tracts in histological sections of the samples. The expression of several of the proteins listed above was examined in cultured mouse stellate cells. Quiescent stellate cells, but not portal myofibroblasts, expressed both CYGB and CRBP-1 in normal livers. In fibrotic and cirrhotic livers, stellate cells expressed both CYGB and a-SMA, whereas myofibroblasts around the portal vein expressed a-SMA, Thy-1, and FBLN2, but not CYGB. Development of the fibrotic stage was positively correlated with increases in Sirius red-stained, alpha-SMA-positive, and Thy-1-positive areas, whereas the number of CYGB- and CRBP-1-positive cells decreased with fibrosis development. Primary cultured mouse stellate cells expressed cytoplasmic CYGB at day 1, whereas they began to express a-SMA at the cellular margins at day 4. Thy-1 was undetectable throughout the culture period. In human liver tissues, quiescent stellate cells are CYGB positive. When activated, they also become a-SMA positive; however, they are negative for Thy-1 and FBLN2. Thus, CYGB is a useful marker with which to distinguish stellate cells from portal myofibroblasts in the damaged human liver.

    Background and AimIt is not yet clear which factors are associated with the outcome of 72-week treatment with pegylated-interferon and ribavirin (RBV) in patients with chronic hepatitis C virus (HCV) infection.
    MethodsIn 66 patients with HCV genotype 1 who had a late viral response (LVR) to 72-week treatment of pegylated-interferon and RBV, we examined the factors that determined the outcome, including single nucleotide polymorphisms of interleukin-28B and inosine triphosphatase (ITPA) genes.
    ResultsThirty seven of 66 (56%) patients with LVR achieved a sustained viral response (SVR). The mean age of these 37 SVR patients was 55, compared with 61 in 29 relapsed patients (P=0.009). Twenty six of 54 (48%) patients with the CC genotype and 11 of 12 (92%) with the CA/AA genotype of ITPA rs1127354 achieved SVR (P=0.006). The SVR rates were 79%, 40%, 60%, and 33% in patients with undetectable HCV RNA on weeks 16, 20, 24, and 28 or later, respectively (P=0.014). Finally, serum RBV concentration at week 44 of treatment was significantly higher in the SVR group (2651ng/mL) than in the relapse group (1989ng/mL, P=0.002). In contrast, the rate of the interleukin-28B genotype was not different between the groups. Multiple regression analysis showed that age &lt;60 years, ITPA CA/AA genotype, and serum RBV concentration were significant independent predictive factors for SVR.
    ConclusionsOur findings elucidated the association of four factors, including ITPA genotype, with the outcome of 72-week treatment in LVR patients.

    Aim: The association between sarcopenia and nutritional status is thought to be an important problem in patients with cirrhosis. In this study, we investigated whether nutritional factors were related to sarcopenia in patients with liver cirrhosis. Methods: The subjects were 50 patients with cirrhosis aged 41 years or older. In this study, the subjects were interviewed about their dietary habits, and their daily physical activity was surveyed using a pedometer. The skeletal muscle mass index (SMI) was calculated using the appendicular skeletal muscle mass (ASM) measured by bioelectric impedance analysis. The handgrip strength was measured using a hand dynamometer. Sarcopenia was defined by SMI and handgrip strength. The patients with cirrhosis were categorized as normal group or sarcopenia group, and the two groups were compared. Univariate and multivariate logistic regression modeling were used to identify the relevance for sarcopenia in patients with cirrhosis. Results: Height (odds ratio (OR), 5.336
    95% confidence interval [CI], 1.063-26.784
    P=0.042), energy intake per ideal bodyweight (IBW) (OR, 5.882
    95% CI, 1.063-32.554
    P=0.042) and number of steps (OR, 4.767
    95% CI, 1.066-21.321
    P=0.041) were independent relevant factors for sarcopenia. Moreover, a significantly greater number of the patients in the sarcopenia group had low values for both parameters' energy intake per IBW and number of steps. Conclusion: Our results suggest that walking 5000 or more steps per day and maintaining a total energy intake of 30kcal/IBW may serve as a reference for lifestyle guidelines for compensated cirrhotic patients. © 2013 The Japan Society of Hepatology.

    Aims/IntroductionWe reinvestigated the clinical usefulness of the modified NAFIC scoring system, modified by changing the weightage assigned to the fasting serum insulin level based on the importance of hyperinsulinemia in the pathogenesis of non-alcoholic steatohepatitis (NASH), in Japanese patients with non-alcoholic fatty liver disease (NAFLD) who had undergone liver biopsy.
    Materials and MethodsThe NAFIC score is conventionally calculated as follows: serum ferritin 200ng/mL (female) or 300ng/mL (male), 1point; serum fasting insulin 10U/mL, 1point; and serum type IV collagen 7s 5.0ng/mL, 2points. A total of 147 patients with NAFLD who had undergone liver biopsies were included in the estimation group. To validate the modified scoring system, 355 patients from nine hepatology centers in Japan were also enrolled.
    ResultsIn the estimation group, 74 (50.3%) patients were histologically diagnosed as having NASH, whereas the remaining 73 (49.7%) were diagnosed as not having NASH. As the percentage of NASH patients increased not only among participants with serum insulin levels greater than 10U/mL, but also in those with serum levels greater than 15U/mL, we advocated use of the modified NAFIC score, as follows: serum fasting insulin 10-15U/mL, 1point and 15U/mL, 2points. The modified NAFIC score showed improved sensitivity and negative predictive value for the diagnosis of NASH. This finding was also confirmed in the validation group.
    ConclusionsThe modified NAFIC scoring system could be a clinically useful diagnostic screening tool for NASH.

    AimThe aim of this study was to evaluate the efficacy and safety of combination therapy using natural human interferon- and ribavirin (IFN-/RBV) for chronic hepatitis C patients who were injection drug users (IDU) and resident in the Airin district of Osaka, containing the biggest slums in Japan.
    MethodsTwenty-nine IDU with chronic hepatitis C received combination therapy of IFN-/RBV. The psychiatrist in charge evaluated the scores of the Zung Self-rating Depression Scale (SDS), a self-rating scale based on 20 questions. Univariate logistic regression analyses were used to determine the factors that significantly contributed to complete treatment and a sustained virological response (SVR).
    ResultsThirteen of the 29 patients achieved SVR according to the intention to treat analysis. All patients with a rapid virological response achieved SVR. No patient required a reduced dose of RBV because of a decrease in their hemoglobin level, or of IFN- because of a low level of white blood cells and platelet count. Two patients had psychological side-effects and stopped the therapy early in the treatment; one patient had depression and the other had anxious depression. Univariate logistic regression analyses indicated that the stage of fibrosis was the only factor that contributed to SVR, and that the SDS test and past drug abuse contributed to completion of the treatment.
    ConclusionIFN-/RBV combination therapy is useful for treating IDU.

    PurposeMac-2 binding protein (Mac-2bp) is one of the major fucosylated glycoproteins, which we identified with glycol-proteomic analyses. We previously reported that fucosylated glycoproteins are secreted into bile, but scarcely secreted into sera in normal liver and hypothesized that the fucosylation-based sorting machinery would be disrupted in ballooning hepatocytes due to the loss of cellular polarity. In the present study, we investigated the availability of Mac-2bp for differential diagnosis of nonalcoholic steatohepatitis (NASH) from nonalcoholic fatty liver disease (NAFLD) as a biomarker.
    Experimental designSerum Mac-2bp levels were determined with our developed ELISA kit. Our cohort of 127 patients with NAFLD had liver biopsy to make a histological diagnosis of NASH and simple fatty liver.
    ResultsMac-2bp levels were significantly elevated in NASH patients compared with non-NASH (simple steatosis) patients (2.132 1.237 vs. 1.103 +/- 0.500 g/mL, p &lt; 0.01). The area under the receiver-operating characteristic curve for predicting NASH by Mac-2bp was 0.816. Moreover, multivariate logistic regression analyses showed Mac-2bp levels could predict the fibrosis stage and the presence of ballooning hepatocytes in NAFLD patients.
    Conclusions and clinical relevanceThese results support the potential usefulness of measuring Mac-2bp levels in clinical practice as a biomarker for NASH.

    The severity of liver fibrosis must be estimated to determine the prognosis, for surveillance, and for optimal treatment of nonalcoholic fatty liver disease (NAFLD). However, the severity of hepatic fibrosis tends to be underestimated in patients with normal ALT.
    We investigated histological data and scoring systems (FIB-4 index, NAFLD fibrosis score, BARD score, and AST/ALT ratio) of 1,102 liver-biopsy-confirmed NAFLD patients.
    A total of 235 NAFLD patients with normal ALT were estimated to exist. The ratio of advanced fibrosis (stage 3-4) was seen in 16.1 % of subjects with normal ALT. Scoring systems, especially the FIB-4 index and NAFLD fibrosis score, were clinically very useful (AUROC &gt; 0.8), even in patients with normal ALT. Furthermore, with resetting of the cutoff values, the FIB-4 index (&gt; 1.659) and NAFLD fibrosis score (&gt; 0.735) were found to have a higher sensitivity and higher specificity for the prediction of advanced fibrosis, and all of these scoring systems (FIB-4 index, NAFLD fibrosis score, BARD score, and AST/ALT ratio) had higher negative predictive values (&gt; 90.3 %). By using the resetting cutoff value, liver biopsy could have been avoided in 60.4 % (FIB-4), 66.4 % (NAFLD fibrosis score), 51.9 % (BARD score), and 62.1 % (AST/ALT ratio).
    We reset the cutoff values of numerous non-invasive scoring systems to improve their clinical usefulness in the prediction of liver fibrosis in NAFLD patients with normal ALT, and these non-invasive scoring systems with the reset cutoff values could be of substantial benefit to reduce the number of liver biopsies performed.

    1102例の肝生検で確定診断された非アルコール性脂肪肝(NAFLD)症例を対象として、組織学的所見と各種スコアリング法(FIB-4指数、NAFLD線維化スコア、BARDスコア、AST/ALT比)を比較し、その有用性を検討した。235例は、ALT値が正常のNAFLDで、線維化が進んだ症例を16.1%に認めた。スコアリング法、特にFIB-4指数とNAFLD線維化スコアは、ALT正常例においても臨床的に有用であった(受信者操作特性曲線下領域>0.8)。カットオフ値をFIB-指数で>1.659、NAFLD線維化スコアで>0.735とすることで、高度線維化に対する感度および特異度が上昇した。また、全てのスコアリング法で陰性的中率が向上した。カットオフ値の変更により、60.4%(FIB-4)、66.4%(NAFLD線維化スコア)、51.9%(BARDスコア)、62.1% (AST/ALT比)の症例で肝生検が避けられると考えられた。

    UNLABELLED: Nonalcoholic fatty liver disease (NAFLD) is a growing medical problem around the world. NAFLD patients with nonalcoholic steatohepatitis (NASH) can develop cirrhosis and hepatocellular carcinoma. The ability to distinguish NASH from simple steatosis would be of great clinical significance. Ballooning hepatocytes are characteristic of typical pathological NASH; here, the polarized secretion of proteins is disrupted due to destruction of the cytoskeleton. We previously reported that fucosylated glycoproteins are secreted into bile, but not into sera in normal liver. Therefore, we hypothesized that the fucosylation-based sorting machinery would be disrupted in ballooning hepatocytes, and serum fucosylated glycoproteins would increase in NASH patients. To confirm our hypothesis, we evaluated serum fucosylated haptoglobin (Fuc-Hpt) levels in biopsy-proven NAFLD patients (n = 126) using a lectin-antibody ELISA kit. Fuc-Hpt levels were significantly increased in NASH patients compared with non-NASH (NAFLD patients without NASH) patients. Interestingly, Fuc-Hpt levels showed a significant stepwise increase with increasing hepatocyte ballooning scores. Multiple logistic regression analysis showed that Fuc-Hpt levels were independent and significant determinants of the presence of ballooning hepatocytes. Moreover, Fuc-Hpt levels were useful in monitoring liver fibrosis staging. Next, to investigate the significance of serum Fuc-Hpt in a larger population, we measured Fuc-Hpt levels in ultrasound-diagnosed NAFLD subjects (n = 870) who received a medical health checkup. To evaluate NAFLD disease severity, we used the FIB-4 index (based on age, serum AST and ALT levels, and platelet counts). Fuc-Hpt levels increased stepwise with increasing FIB-4 index. CONCLUSION: Measurement of serum Fuc-Hpt levels can distinguish NASH from non-NASH patients, and predict the presence of ballooning hepatocytes in NAFLD patients with sufficient accuracy. These results support the potential usefulness of measuring Fuc-Hpt levels in clinical practice.

    Aim: Some regions associated with sensitivity to interferon-a and ribavirin have been identified in the hepatitis C virus (HCV) genome, including amino acid 70 in the core region (core a.a. 70), a.a. 22092248 (interferon sensitivity-determining region, ISDR) and a.a. 23342379 (interferon and ribavirin resistance-determining region, IRRDR).
    Methods: We examined changes in the sequences of these regions in 25 patients with chronic HCV genotype 1 infection who had not had sustained virological response (SVR) to interferon-a and ribavirin for 2448 weeks and subsequently received retreatment for 4872 weeks.
    Results: At baseline, the core a.a. 70 was mutant (resistant) type in seven patients. At the start of retreatment, the core a.a. 70 had changed from sensitive to resistant type in 2 patients, and SVR was not achieved by retreatment. The ISDR variations were resistant type (01 mutations) in 17 patients at baseline. After 2 weeks of treatment, amino acid change was found in two patients; in one, the substitutions returned to baseline status after treatment, and in the other, the substitution persisted. At the start of retreatment, ISDR sequences had changed from resistant to sensitive type in two patients and SVR was achieved and from sensitive to resistant type in three patients and SVR was not achieved. The IRRDR variations were resistant type (&lt;6 mutations) in 19 patients at baseline and at the start of retreatment.
    Conclusion: Sequences of the core region and ISDR sometimes change during anti-HCV therapy, potentially affecting the outcomes of retreatment.

    Background MicroRNAs (miRNAs) are important in hepatic pathophysiology and the development of liver cancer.
    Objective To explore miRNAs that are regulated with the progression of liver fibrosis caused by chronic liver disease.
    Design The regulated miRNAs in human livers infected with hepatitis C virus were identified by microarray analysis. Their expression in human livers with nonalcoholic steatohepatitis, mouse livers from two fibrosis models and cultured stellate cells was validated by realtime RT-PCR. The regulation of miR-222 expression in stellate cells by nuclear factor kappa B (NF-kappa B) was assayed. Finally, the effects of an miR-222 precursor or inhibitor on the expression of cyclin-dependent kinase inhibitor 1B (CDKN1B) and the growth of LX-2 cells were determined.
    Results It was found that miR-199a-5p/199a-3p and miR-221/222 were upregulated in the human liver in a fibrosis progressionedependent manner. Among these miRNAs, miR-221/222 were upregulated in LX-2 cells and increased during the course of culture-dependent activation of mouse primary stellate cells, in a manner similar to the expression of alpha 1(I) collagen and alpha-smooth muscle actin mRNAs. The expression of miR-221/222 increased in mouse models of liver fibrosis. In contrast, an NF-kappa B inhibitor significantly suppressed the miR-222 induction that was stimulated in culture by transforming growth factor alpha or tumour necrosis factor alpha. Although overexpression or downregulation of miR-222 failed to regulate the growth of LX-2 cells, miR-222 bound to the CDKN1B 3'UTR and regulated the expression of the corresponding protein.
    Conclusion miR-221/222 may be new markers for stellate cell activation and liver fibrosis progression.

    AIM: To assess the nourishment status and lifestyle of non-hospitalized patients with compensated cirrhosis by using noninvasive methods.
    METHODS: The subjects for this study consisted of 27 healthy volunteers, 59 patients with chronic viral hepatitis, and 74 patients with viral cirrhosis, from urban areas. We assessed the biochemical blood tests, anthropometric parameters, diet, lifestyle and physical activity of the patients. A homeostasis model assessment-insulin resistance (HOMA-IR) value of &gt;= 2.5 was considered to indicate insulin resistance. We measured height, weight, waist circumference, arm circumference, triceps skin-fold thickness, and handgrip strength, and calculated body mass index, arm muscle circumference (AMC), and arm muscle area (AMA). We interviewed the subjects about their dietary habits and lifestyle using health assessment computer software. We surveyed daily physical activity using a pedometer. Univariate and multivariate logistic regression modeling were used to identify the relevant factors for insulin resistance.
    RESULTS: The rate of patients with HOMA-IR &gt;= 2.5 (which was considered to indicate insulin resistance) was 14 (35.9%) in the chronic hepatitis and 17 (37.8%) in the cirrhotic patients. AMC (%) (control vs chronic hepatitis, 111.9% +/- 10.5% vs 104.9% +/- 10.7%, P = 0.021; control vs cirrhosis, 111.9% +/- 10.5% vs 102.7% +/- 10.8%, P = 0.001) and AMA (%) (control vs chronic hepatitis, 128.2% +/- 25.1% vs 112.2% +/- 22.9%, P = 0.013; control vs cirrhosis, 128.2% +/- 25.1% vs 107.5% +/- 22.5%, P = 0.001) in patients with chronic hepatitis and liver cirrhosis were significantly lower than in the control subjects. Handgrip strength (%) in the cirrhosis group was significantly lower than in the controls (control vs cirrhosis, 92.1% +/- 16.2% vs 66.9% +/- 17.6%, P &lt; 0.001). The results might reflect a decrease in muscle mass. The total nutrition intake and amounts of carbohydrates, protein and fat were not significantly different amongst the groups. Physical activity levels (kcal/d) (control vs cirrhosis, 210 +/- 113 kcal/d vs 125 +/- 74 kcal/d, P = 0.001), number of steps (step/d) (control vs cirrhosis, 8070 +/- 3027 step/d vs 5789 +/- 3368 step/d, P = 0.011), and exercise (Ex) (Ex/wk) (control vs cirrhosis, 12.4 +/- 9.3 Ex/wk vs 7.0 +/- 7.7 Ex/wk, P = 0.013) in the cirrhosis group was significantly lower than the control group. The results indicate that the physical activity level of the chronic hepatitis and cirrhosis groups were low. Univariate and multivariate logistic regression modeling suggested that Ex was associated with insulin resistance (odds ratio, 6.809; 95% CI, 1.288-36.001; P = 0.024). The results seem to point towards decreased physical activity being a relevant factor for insulin resistance.
    CONCLUSION: Non-hospitalized cirrhotic patients may need to maintain an adequate dietary intake and receive lifestyle guidance to increase their physical activity levels. (C) 2012 Baishideng. All rights reserved.

    遺伝子型が2型のC型肝炎ウイルス(HCV)の患者に対してresponse-guided therapyを行った際の治療効果を評価した。2型のC型肝炎ウイルスに感染し、ウイルス量が5.0LogIU/mLより高く、ペグ化インターフェロンとリバビリンの併用で目標容量の75%以上を摂取している患者105名を対象とした。4週時ウイルス陰性化(RVR)を示した患者のうち14名を16週の治療期間(A群)、28名を24週の治療期間(B群)とした。非RVR患者のうち、40名は24週の治療期間(C群)、19名は48週の治療期間(D群)とした。その結果、A群とB群の全患者が持続的ウイルス陰性化(SVR)を達成した。治療開始後のより遅い週にHCV RNAが消滅した患者の割合はD群で高かった(p=0.0578)。SVR達成率はC群で73%、D群で79%であった。5週〜8週でHCV RNAが消失した患者のうちSVRを達成したのはC群34名中28名(82%)、D群11名中10名(91%)であった。9〜12週にHCV RNAが消失した患者はC群は5名中1名(20%)、D群は8名中5名(63%)であった。以上より、RVR患者に対しては16週の混合療法により適切なウイルス抑制効果が得られた。非RVR患者に対して治療を延長することではSVR達成率を有意に改善できなかった。

    遺伝子型が2型のC型肝炎ウイルス(HCV)の患者に対してresponse-guided therapyを行った際の治療効果を評価した。2型のC型肝炎ウイルスに感染し、ウイルス量が5.0LogIU/mLより高く、ペグ化インターフェロンとリバビリンの併用で目標容量の75%以上を摂取している患者105名を対象とした。4週時ウイルス陰性化(RVR)を示した患者のうち14名を16週の治療期間(A群)、28名を24週の治療期間(B群)とした。非RVR患者のうち、40名は24週の治療期間(C群)、19名は48週の治療期間(D群)とした。その結果、A群とB群の全患者が持続的ウイルス陰性化(SVR)を達成した。治療開始後のより遅い週にHCV RNAが消滅した患者の割合はD群で高かった(p=0.0578)。SVR達成率はC群で73%、D群で79%であった。5週〜8週でHCV RNAが消失した患者のうちSVRを達成したのはC群34名中28名(82%)、D群11名中10名(91%)であった。9〜12週にHCV RNAが消失した患者はC群は5名中1名(20%)、D群は8名中5名(63%)であった。以上より、RVR患者に対しては16週の混合療法により適切なウ

    Gastroparesis, a gastrointestinal autonomic neuropathy, is a common adverse reaction in chronic hepatitis C (CHC) patients receiving interferon therapy. Current therapeutic options are limited. We evaluated the efficacy of mosapride for IFN-induced gastroparesis.
    Twenty-four consecutive CHC patients were randomly assigned to either the control group, which received pegylated interferon alpha-2b at 1.5 mu g/kg/week and ribavirin at 600-1,000 mg/day, depending on body weight (PegIFN/RBV), or the mosapride group, which received PegIFN/RBV plus mosapride at 15 mg/person/day. The solid-phase gastric emptying half-times (T1/2) of the total, proximal, and distal stomach (scintigraphy) and digestive symptoms (questionnaire) were measured within one week before and four weeks after initiation of the assigned therapy. The test meal comprised a 200-g pancake containing Tc-99m diethylenetriamine pentaacetic acid.
    In the control group, after PegIFN/RBV initiation, a significant increase was observed in the total T1/2 (before: 84.0 +/- A 22.1 min versus after: 100.8 +/- A 28.9 min, P = 0.03), the distal T1/2 (before: 95.3 +/- A 32.2 min versus after: 115.3 +/- A 41.4 min, P = 0.03), and digestive symptom score (before: 3.2 +/- A 1.4 versus after: 8.1 +/- A 4.8, P = 0.02); proximal T1/2 change was not significant. In the mosapride group, no significant delays were observed in the total, proximal, and distal T1/2 values; the change in symptom scores was not significant.
    Mosapride improved total and distal gastric motility in IFN-induced gastroparesis, and consequently relieved symptoms.

    Aim: We evaluated the efficacy of response-guided therapy in patients with hepatitis C virus (HCV) genotype 2. Methods: We studied 105 patients with an HCV genotype 2 load of higher than 5.0 Log IU/mL who received more than 75% of the target dose of pegylated interferon plus ribavirin. Among patients with rapid viral response (RVR; no HCV RNA detected at week 4), 14 selected 16 weeks of therapy (group A), and 28 selected 24 weeks of therapy (group B). Among non-RVR patients, 40 selected 24 weeks of therapy (group C), and 19 selected 48 weeks of therapy (group D). Results: All patients in group A and B achieved a sustained viral response (SVR). Clinical characteristics did not differ significantly between groups C and D. However, the proportion of patients in whom HCV RNA disappeared at a later week after starting treatment was higher in group D (P = 0.0578). SVR rate was 73% in C, and 79% in D. Among patients in whom HCV RNA disappeared between weeks 5 and 8, SVR was achieved in 28 (82%) of 34 patients in C and 10 (91%) of 11 patients in D. Among patients whose HCV RNA disappeared between weeks 9 and 12, SVR was achieved in one (20%) of five patients in C and five (63%) of eight patients in D (not statistically significant). Conclusions: 16 weeks of combination therapy could achieve an adequate antiviral effect for RVR patients. Extending therapy could not significantly improve SVR rate in non-RVR patients.

    Nonalcoholic fatty liver disease consists of a range of disorders characterized by excess accumulation of triglyceride within the liver. Whereas simple steatosis is clinically benign, nonalcoholic steatohepatitis (NASH) often progresses to cirrhosis. Inflammation and fibrogenesis are closely inter-related and are major targets of NASH research. Experimental data have shown that inflammation in NASH is caused by insulin resistance, systemic lipotoxicity due to overnutrition, lipid metabolites, the production of proinflammatory cytokines and adipokines by visceral adipose tissue, gut-derived bacteria, and oxidative stress. In NASH-associated fibrosis, the principal cell type responsible for extracellular matrix production is recognized as the hepatic stellate cell. Although the fibrotic mechanisms underlying NASH are largely similar to those observed in other chronic liver diseases, the altered patterns of circulating adipokines, the generation of oxidative stress, and the hormonal profile associated with the metabolic syndrome might play unique roles in the fibrogenesis associated with the disease. Information on the basic pathogenesis of NASH with a focus on the generation of inflammation and fibrosis will be discussed.

    Nonalcoholic fatty liver disease (NAFLD) is a common cause of chronic liver disease and is a major public health problem worldwide. It has been suggested that simple fatty liver, the most common type of NAFLD, is a reversible condition in which large vacuoles containing triglycerides accumulate in hepatocytes. Simple fatty liver is often a precursor to non-alcoholic steatohepatitis, which can progress to liver cirrhosis and hepatocellular carcinoma. NAFLD is considered one of the phenotypes of metabolic syndrome, which is characterized by obesity, type 2 diabetes mellitus, hyperlipidemia and hypertension. Obesity, particularly abdominal obesity, is a major risk factor for NAFLD. Several recent studies have revealed a relationship between excessive visceral fat accumulation and the severity of hepatic fat accumulation. On the other hand, in the current definitions of metabolic syndrome, waist circumference measurement has been proposed as a simple and useful estimate of abdominal obesity, taking into account sex differences in waist circumference. Recent studies have also reported that waist circumference could be a marker for hepatic fat accumulation. In this chapter, we first discuss the relationship between waist circumference, hepatic fat accumulation and liver function. Finally, we discuss the sex and age-group differences in these relationships, based on recent findings.

    Background: A reliable and inexpensive noninvasive marker of hepatic fibrosis is required in patients with nonalcoholic fatty liver disease (NAFLD). FIB4 index (based on age, aspartate aminotransferase [AST] and alanine aminotransferase [ALT] levels, and platelet counts) is expected to be useful for evaluating hepatic fibrosis. We validated the performance of FIB4 index in a Japanese cohort with NAFLD.
    Methods: The areas under the receiver operating characteristic curves (AUROC) for FIB4 and six other markers were compared, based on data from 576 biopsy-proven NAFLD patients. Advanced fibrosis was defined as stage 3-4 fibrosis. FIB4 index was assessed as: age (yr) x AST (IU/L)/(platelet count (10(9)/L) x root ALT (IU/L))
    Results: Advanced fibrosis was found in 64 (11%) patients. The AUROC for FIB4 index was superior to those for the other scoring systems for differentiating between advanced and mild fibrosis. Only 6 of 308 patients with a FIB4 index below the proposed low cut-off point (&lt; 1.45) were under-staged, giving a high negative predictive value of 98%. Twenty-eight of 59 patients with a FIB4 index above the high cut-off point (&gt; 3.25) were over-staged, giving a low positive predictive value of 53%. Using these cutoffs, 91% of the 395 patients with FIB-4 values outside 1.45-3.25 would be correctly classified. Implementation of the FIB4 index in the Japanese population would avoid 58% of liver biopsies.
    Conclusion: The FIB4 index was superior to other tested noninvasive markers of fibrosis in Japanese patients with NAFLD, with a high negative predictive value for excluding advanced fibrosis. The small number of cases of advanced fibrosis in this cohort meant that this study had limited power for validating the high cut-off point.

    A 69 year-old man was admitted to our hospital for purpose of transcatheter arterial infusion (TAI) with miriplatin for advanced hepatocellular carcinoma. Eight days after TAI, cough and sputum developed. Seventeen days after TAI, dyspnea with marked hypoxemia and diffuse ground-glass opacities in bilateral lung fields were revealed by a chest CT scan. We started use of mechanical ventilation and high dose corticosteroid therapy for acute respiratory failure. Gradually, his respiratory condition improved, and 24 days after TAI, he was werning from respirator. As a cause of the pneumonitis, infectious diseases were ruled out by serodiagnosis, sputum culture and bronchoalveolar lavage. We clinically diagnosed drug-induced pneumonitis caused by TAI with miriplatin.<br>

    A 26-year-old Japanese woman was admitted to our hospital because of spiking fever, eruption, and liver dysfunction. High fever continued after admission, and antibiotics were not effective. The patient was diagnosed as adult-onset Still's disease after excluding leukemia and malignant lymphoma. Because the patient was complicated with acute liver failure, steroid pulse therapy was started. Although steroid pulse therapy was transiently effective for clinical symptoms, oral predonisolone was not. Moreover, the patient was complicated with severe cytopenia. We diagnosed with macrophage activation syndrome complicated with adult-onset Still's disease. She was treated with cyclosporine A and liposteroid, resulted in complete remission for macrophage activation syndrome and adult-onset Still's disease. In summary of our case, combination of cyclosporine A and liposteroid was effective for the treatment of macrophage activation syndrome with acute liver failure in a patient with adult-onset Still's disease.<br>

    Background The severity of liver fibrosis is known to be a good indicator for surveillance, and for determining the prognosis and optimal treatment of nonalcoholic fatty liver disease (NAFLD). However, it is virtually impossible to carry out liver biopsies in all NAFLD patients. The purpose of this study was to investigate the clinical usefulness of measuring the platelet count for predicting the severity of liver fibrosis in a large retrospective cohort of Japanese patients with NAFLD.
    Methods A total of 1,048 patients with liver-biopsy-confirmed NAFLD seen between 2002 and 2008 were enrolled from nine hepatology centers in Japan. Laboratory evaluations were performed for all patients.
    Results A linear decrease of the platelet count with increasing histological severity of hepatic fibrosis was revealed. The area under the receiver operating characteristic curve estimating the diagnostic performance of the platelet count for hepatic fibrosis Stage 3 was 0.774 (optimal cutoff value, 19.2 x 10(4)/mu l; sensitivity, 62.7%; specificity, 76.3%), and that for Stage 4 was 0.918 (optimal cutoff value, 15.3 x 10(4)/mu l; sensitivity, 80.5%; specificity, 88.8%).
    Conclusions The platelet count may be an ideal biomarker of the severity of fibrosis in NAFLD patients, because it is simple, easy to measure and handle, cost-effective, and accurate for predicting the severity of fibrosis. Furthermore, by using the platelet count cutoff value validated in our multiple large trials, efficient recruitment of NAFLD patients may be facilitated.
