    Intrahepatic cholangiocarcinoma (CC) accounts for approximately 20% of all biliary tract cancer (BTC) cases and 10-15% of all primary liver cancer cases. Many patients are diagnosed with unresectable BTC, and, even among patients with resectable BTC, the 5-year survival rate is approximately 20%. The BTC incidence rate is high in Southeast and East Asia and has increased worldwide in recent years. Since 2010, cytotoxic chemotherapy, particularly combination gemcitabine + cisplatin (ABC-02 trial), has been the first-line therapy for patients with BTC. In 2022, a multicenter, double-blind, randomized phase 3 trial (TOPAZ-1 trial) examined the addition of programmed death-ligand 1 immunotherapy (durvalumab) to combination gemcitabine + cisplatin for BTC treatment, resulting in significantly improved survival without notable additional toxicity. As a result of this trial, this three-drug combination has become the new standard first-line therapy, leading to notable advances in BTC management for the first time since 2010. The molecular profiling of BTC has continued to drive the development of new targeted therapies for use when first-line therapies fail. Typically, second-line therapy decisions are based on identified genomic alterations in tumor tissue. Mutations in fibroblast growth factor receptor 1/2/3, isocitrate dehydrogenase 1/2, and neurotrophic tyrosine receptor kinase A/B/C are relatively frequent in intrahepatic CC, and precision medicines are available that can target associated pathways. In this review, we suggest strategies for systemic pharmacotherapy with a focus on intrahepatic CC, in addition to presenting the results and safety outcomes of clinical trials evaluating immune checkpoint inhibitor therapies in BTC.

    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。

    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.

    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>

    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.

    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.

    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.

    AIM: Hepatic venous pressure gradient (HVPG) measurement is a gold standard for the diagnosis of portal hypertension but can be invasive and difficult to conduct. Per-rectal portal scintigraphy (PRPS) can estimate portal haemodynamics noninvasively. However, no report to date has examined the association between HVPG and PRPS in patients with chronic liver disease, including cirrhosis. METHODS: This single-centre study included a total of 21 patients with chronic liver disease who underwent HVPG measurement and PRPS. For PRPS, the transit times from injection of the radiotracer to its inflow into the liver (TTL) and heart (TTH) were set and the time difference between TTL and TTH (TDLH) was calculated, while the shunt index (SI) was measured. RESULTS: Cirrhosis was observed in 18 cases (86%), and the median HVPG was 13 mmHg. HVPG (p = 0.028), TTL (p = 0.018), TDLH (p = 0.003) and SI (p = 0.033) were higher in patients with oesophageal varices (EV). Considering the diagnostic ability for EV, the area under the curve was 0.88 for TDLH and 0.80 for HVPG. TDLH was significantly correlated with the risk of EV rupture (p = 0.004). CONCLUSION: Patients with chronic liver disease should undergo upper gastrointestinal endoscopy when the TDLH is high.

    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.

    A 77-year-old man with chronic hepatitis C underwent transcatheter arterial chemoembolization (TACE) and radiofrequency ablation (RFA) for early-stage hepatocellular carcinoma (HCC) in segment 8 of the liver. Necrosis was confirmed radiologically. After 19 months, recurrent HCC in segment 6 was treated with TACE and RFA. There was no recurrence. Direct-acting antiviral (DAA) therapy 24 months after the initial procedure led to a sustained virologic response. AFP-L3 markedly increased 11 months after DAA therapy, and MRI 6 months after that showed a solitary lymph node near the common bile duct. Because no intrahepatic recurrence or other lymph nodes were seen, the solitary node was excised. Histopathology showed metastatic HCC. There has been no subsequent recurrence over 13 months of follow-up.

    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.

    Tc-99m-galactosyl human serum albumin (GSA) scintigraphy is used to assess the hepatic functional reserve, and allows for visual assessment of the residual hepatocyte distribution on single-photon emission computed tomography/computed tomography (SPECT/CT) images. The association between heterogeneous liver uptake of Tc-99m-GSA and liver fibrosis remains to be studied in detail. We analyzed this association.Fifty-one patients with chronic hepatobiliary disease undergoing a Tc-99m-GSA scintigraphy were included in this study. The receptor (LHL15) and blood clearance (HH15) indexes (the uptake ratios of the liver and heart) were obtained from dynamic planar images. The liver uptake count maximum-to-mean ratio (LUC Max/Mean) was calculated from single-photon emission computed tomography/computed tomography (SPECT/CT) images as an indicator of the Tc-99m-GSA liver uptake heterogeneity. We assessed the relationship between these quantified values and liver fibrosis.There were 30 Child-Pugh classification grade A patients, 16 grade B patients, and 5 grade C patients. Among the 30 patients whose liver histopathology was evaluable, those with advanced liver fibrosis (F2-4) had a lower LHL15 than those with mild liver fibrosis (F0-1) (median, 0.90 vs. 0.92, P=.04), and a higher LUC Max/Mean (median, 1.80 vs. 1.70, P=.02). The multivariate analysis identified platelets (P=.04) and the LUC Max/Mean (P=.04) as contributing factors of advanced liver fibrosis.These findings suggest that Tc-99m-GSA SPECT/CT can be used not only to assess the hepatic functional reserve, but also to evaluate a degree of liver fibrosis.

    Various positron emission tomography (PET) probes have been developed to assess in vivo activities in humans of drug transporters, which aid in the prediction of pharmacokinetic properties of drugs and the impact of drug-drug interactions. We developed a new PET probe, sodium (3R, 5R)-3, 5-dihydroxy-7-((1S, 2S, 6S, 8S)-6-hydroxy-2-methyl-8- ((1-[C-11]-(E)-2-methyl-but-2-enoyl)oxy) -1, 2, 6, 7, 8, 8a-hexahydronaphthalen-1-yl)heptanoate ([C-11]DPV), and demonstrated its usefulness for the quantitative investigation of Oatps (gene symbol SLCO) and Mrp2 (gene symbol ABCC2) in rats. To further analyze the species differences and verify the pharmacokinetic parameters in humans, serial PET scanning of the abdominal region with [C-11]DPV was performed in six healthy volunteers with and without an OATP1Bs and MRP2 inhibitor, rifampicin (600 mg, oral), in a crossover fashion. After intravenous injection, [C-11]DPV rapidly distributed to the liver and kidney followed by secretion into the bile and urine. Rifampicin significantly reduced the liver distribution of [C-11]DPV 3-fold, resulting in a 7.5-fold reduced amount of excretion into the bile and the delayed elimination of [C-11]DPV from the blood circulation. The hepatic uptake clearance (CLuptake, liver) and canalicular efflux clearance (CLint, bile) of [C-11]DPV(544 +/- 204 and 10.2 +/- 3.5 mu l/min per gram liver, respectively) in humans were lower than the previously reported corresponding parameters in rats (1800 and 298 mu l/min per gram liver, respectively) (Shingaki et al., 2013). Furthermore, rifampicin treatment significantly reduced CLuptake, liver and CLint, bile by 58% and 44%, respectively. These results suggest that PET imaging with [C-11]DPV is an effective tool for quantitatively characterizing the OATP1Bs and MRP2 functions in the human hepatobiliary transport system.

    Background: Hepatocellular carcinoma (HCC) develops in some patients who achieve sustained virological response (SVR) against hepatitis C virus (HCV) infection via anti-HCV therapy. To examine the pathogenesis of HCC development after HCV eradication, histopathological changes and clinical markers were evaluated in SVR patients. Methods: Of 654 SVR patients treated with interferon (IFN)-based therapies, 34 patients who had undergone liver biopsy before initiating IFN therapy and after SVR achievement were enrolled: 11 patients with HCC and 23 patients without HCC (male/female, 9/2 and 8/15, respectively: age, 58 ± 5 and 54 ±11 years, respectively). We compared the clinical and histopathological factors between the two groups. Immunohistochemistry for Cytoglobin (CYGB) and α smooth muscle actin (α-SMA) was also performed. Results: At baseline, prior to initiating the IFN-based therapy, there were significant differences between the SVR-non-HCC and SVR-HCC groups in the male gender, HBc antibody positivity, prothrombin activity, and histological inflammatory grade. Histopathological evaluation, using the new Inuyama classification system, revealed an improvement in the inflammatory grade, from 2.1 ± 0.6 to 1.0 ± 0.6 (p &lt
    0.0001), whereas the fibrosis stage remained unchanged, from 2.3 ± 0.9 to 2.0 ± 1.2 (p = 0.2749), during the 97 ± 72-month observation period in the SVR-HCC group. Both the grade and stage scores were significantly improved in the SVR-non-HCC group. The area of collagen deposition, evaluated using Sirius red staining, showed a marked decrease, from 18.6 ± 7.6% to 7.7 ± 4.6%, in the SVR-non-HCC group, with no change in the SVR-HCC group. CYGB- and α-SMA-positive hepatic stellate cells (HSCs), indicative of the HSC activated phenotype, remained in the fibrotic tissue of livers among patients in the SVR-HCC group. Conclusion: Stagnation of fibrosis regression is associated with a high risk for HCC after SVR. HSC activation may inhibit improvement in fibrosis after SVR and potentially contribute to hepatocarcinogenesis.

    Recently, the MICA rs2596542 and DEPDC5 rs1012068 variants in Japanese individuals as well as the HCP5 rs2244546 and PNPLA3 rs738409 variants in European individuals have been found associated with hepatocellular carcinoma (HCC). The present study determined which single nucleotide polymorphism (SNP) is the most predictive for developing hepatitis C virus (HCV)-related HCC in a Japanese cohort. Of the 4 SNPs analysed, only the MICA genotypes were significantly associated with development of HCC (p = 0.0185). The major (MA), hetero (HE), and minor (MI) genotypes occurred in 40%, 41%, and 19% of HCC patients and in 43%, 47%, and 10% of non-HCC patients, respectively. Interestingly, the MICA genotype was significantly correlated with MICA mRNA and soluble protein levels. In patients older than 70 years, the MI genotype was significantly associated with HCC development. In addition, the MI genotype was related to HCC development when the platelet count range was 10-15 x 10(4)/mu L, corresponding with the fibrosis stage; but not when the range was less than 10, indicating advanced fibrosis; or greater than 15 x 10(4)/mu L, as mild fibrosis. Thus, polymorphisms in MICA, but not in DEPDC5, HCP5 or PNPLA3, are associated with HCC development in Japanese patients with chronic HCV infection.

    Background and Aim: It is unclear whether polymorphism in the inosine triphosphatase (ITPA) gene correlates to the reduction in hemoglobin (Hb) concentrations during sofosbuvir (SOF) and ribavirin (RBV) therapy. This study investigated the effects of the ITPA polymorphism on Japanese patients with chronic hepatitis C virus genotype 2 infection treated with SOF/RBV therapy.
    Methods: In 106 patients treated with SOF/RBV therapy, this study assessed the effects of the ITPA polymorphism (rs1127354) on anemia, RBV dose reduction, and sustained virological response.
    Results: Of the 106 patients, 80 had the CC genotype, whereas 26 had a non-CC genotype in ITPA. Patients with the CC genotype had significantly larger reductions in Hb concentrations than those with a non-CC genotype throughout the treatment course. RBV dose reduction was required in 18/106 (17.0%) patients, with a significantly higher frequency in patients with the CC genotype than in those with a non-CC genotype (P=0.010). In multivariate analysis, age &gt;= 65 years (P=0.011) and the ITPA CC genotype (P&lt;0.0001) were factors significantly associated with anemia throughout the treatment course. Sustained virological response was achieved in 99.0% of all patients: 98.7% of patients with the CC genotype and 100% of patients with a non-CC genotype.
    Conclusions: Inosine triphosphatase polymorphism appeared to correlate with anemia incidence and RBV dose reduction during SOF/RBV therapy, but not the clinical outcome. Careful monitoring of Hb concentrations and prompt adjustment of RBV doses are required for successful treatment, particularly in patients harboring the ITPA CC genotype or age &gt;= 65 years.

    We evaluated the transition of dominant resistance-associated substitutions (RASs) in hepatitis C virus during long-term follow-up after the failure of DAAs (direct acting antivirals)-based therapy. RASs in non-structure (NS)3/4A, NS5A, NS5B, and deletions in NS5A from 20 patients who failed simeprevir/pegylated-interferon/ribavirin (SMV/PEG-IFN/RBV) and 25 patients who failed daclatasvir/asunaprevir (DCV/ASV) treatment were examined by direct sequencing. With respect to SMV/PEG-IFN/RBV treatment, RAS was detected at D168 in NS3/4A but not detected in NS5A and NS5B at treatment failure in 16 of 20 patients. During the median follow-up period of 64 weeks, the RAS at D168 became less dominant in 9 of 16 patients. Among 25 DCV/ASV failures, RASs at D168, L31, and Y93 were found in 57.1%, 72.2%, and 76.9%, respectively. NS5A deletions were detected in 3 of 10 patients treated previously with SMV/PEG-IFN/RBV. The number of RASs in the breakthrough patients exceeded that in relapsers (mean 3.9 vs. 2.7, p &lt; 0.05). RAS at D168 in NS3/4A became less dominant in 6 of 15 patients within 80 weeks. Y93H emerged at the time of relapse, then decreased gradually by 99% at 130 weeks post-treatment. Emerged RASs were associated with the clinical course of treatment and could not be detected during longer follow-up.

    BACKGROUND: The efficacy and safety of asunaprevir + daclatasvir combination therapy for treatment of hepatitis C virus (HCV) in compensated cirrhotic patients was not fully evaluated in real-world. Outcomes were assessed in cirrhotic patients with sustained viral response (SVR). MATERIAL AND METHODS: A total of 145 patients without resistance-associated substitutions (RASs) at L31 and Y93 in the nonstructural protein 5A of HCV genotype 1b, consisting of 49 hepatic cirrhotic and 96 non-cirrhotic patients, were enrolled to the therapy. The patients were treated with 100 mg asunaprevir twice daily plus 60 mg daclatasvir once daily for 24 weeks. The primary endpoint was SVR 24 weeks after completing treatment. In addition, we evaluated the improvement of liver function and development of HCC for 1 year from the end of treatment (EOT). RESULTS: The SVR24 rate was 96% (47/49) in the cirrhotic group and 96% (91/95) in the non-cirrhotic group (p = 0.69). During treatment, grade III/IV adverse events occurred more frequently in cirrhotic patients (10/49; 20.4%) than in non-cirrhotic patients (10/96; 10.4%) (p = 0.099). After EOT, alanine aminotransferase and AFP levels were significantly decreased in cirrhotic patients with SVR. In addition, serum levels of albumin and platelet counts were significantly increased. On the other hand, the rates of HCC recurrence (43%) and development (7.4%) were higher in cirrhotic patients than in the non-cirrhotic patients (12.5% and 1.1%, respectively). CONCLUSION: RAS-oriented asunaprevir/daclatasvir therapy has a strong anti-HCV effect in patients with HCV genotype 1b. However, careful management is necessary in patients with cirrhosis.

There were no patients who were reinfected with HCV during the observation period of 34 months. Infection via IDU and tattooing still have a possibility for reinfection after SVR. These were predominant routes in young, male, and genotype 2 patients. In addition, patients who were lost to follow-up treatment showed the same backgrounds.

    Simeprevir (SMV) is a potent, macrocyclic hepatitis C virus (HCV) non-structural 3/4 A protease inhibitor. This prospective study compared the efficacy and safety of SMV in combination with peginterferon alpha 2a + ribavirin (P2aR) and with peginterferon alpha 2b + ribavirin (P2bR) in Japanese patients with HCV genotype 1b infection.
    Methods: Hepatitis C virus genotype 1b patients were randomly assigned to receive SMV (100 mg QD) with P2aR for 12 weeks, then P2aR alone for 12 or 36 weeks; or SMV (100 mg QD) with P2bR for 12 weeks, then P2bR alone for 12 or 36 weeks. The primary endpoint was a sustained virologic response 24 weeks after completing treatment (SVR24).
    Results: In total, 151 patients were randomly assigned to the P2aR (n = 76) or P2bR group (n = 75). Six patients dropped out. Sustained virologic response 24 weeks after completing treatment was achieved in 55 (75.3%) of 73 P2aR patients and 55 (76.4%) of 72 P2bR patients. There was no difference in the rate of SVR24 between the two groups (P = 0.88). No differences in the proportion of patients who became HCV RNA-negative were detected between the P2aR and P2bR groups. The two groups had comparable numbers of adverse events, which led to the discontinuation of treatment in 9.6% and 8.3% of participants in the P2aR and P2bR groups, respectively.
    Conclusion: Peginterferon alpha 2a or alpha 2b in combination with SMV + ribavirin therapy showed identical antiviral effects in patients with chronic hepatitis C. Also, the incidence of adverse events was identical for both regimens.

    Intrahepatic cholangiocarcinoma (ICC) and hepatocellular carcinoma (HCC) are liver originated malignant tumors. Of the two, ICC has the worse prognosis because it has no reliable diagnostic markers and its carcinogenic mechanism is not fully understood. The aim of this study was to integrate metabolomics and transcriptomics datasets to identify variances if any in the carcinogenic mechanism of ICC and HCC. Ten ICC and 6 HCC who were resected surgically, were enrolled. miRNA and mRNA expression analysis were performed by microarray on ICC and HCC and their corresponding non-tumor tissues (ICC_NT and HCC_NT). Compound analysis was performed using capillary electrophoresis time-of-flight mass spectrometry (CE-TOFMS). Principle component analysis (PCA) revealed that among the four sample groups (ICC, ICC_NT, HCC, and HCC_NT) there were 14 compounds, 62 mRNAs and 17 miRNAs with two distinct patterns: tumor and non-tumor, and ICC and non-ICC. We accurately (84.38%) distinguished ICC by the distinct pattern of its compounds. Pathway analysis using transcriptome and metabolome showed that several pathways varied between tumor and non-tumor samples. Based on the results of the PCA, we believe that ICC and HCC have different carcinogenic mechanism therefore knowing the specific profile of genes and compounds can be useful in diagnosing ICC.

    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 < 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.

    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.

    Gastrointestinal (GI) bleeding scintigraphy in combination with single-photon emission computed tomography/computed tomography (SPECT/CT) remains to be studied in detail. This study aimed to examine the diagnostic ability of this tool.
    GI bleeding scintigraphy using Tc-99m-human serum albumin-diethylenetriaminepentaacetic acid was performed for 38 patients with suspected GI bleeding. Twenty-four patients were diagnosed using planar images alone (planar group) and 14 patients were diagnosed using planar images and additional SPECT/CT images (planar + SPECT/CT group). The diagnostic ability of each method was analyzed.
    GI bleeding was observed in 20 of the 38 patients. For the existence of GI bleeding, planar images alone showed a sensitivity of 70%, specificity of 93%, positive predictive value (PPV) of 88%, negative predictive value (NPV) of 81%, and an overall accuracy of 83%, whereas planar images + SPECT/CT showed a sensitivity of 100%, specificity of 75%, PPV of 91%, NPV of 100%, and an overall accuracy of 93%. The source of bleeding was accurately diagnosed in 50% in the planar group and 78% in the planar + SPECT/CT group. In the planar + SPECT/CT group, 44% of the evaluable patients showed correct localization of the source of GI bleeding by additional SPECT/CT images, although planar images only showed incorrect localization.
    GI bleeding scintigraphy in combination with SPECT/CT is a noninvasive and useful tool for the examination of GI bleeding.

    AimDelayed gastric emptying, including gastroparesis, is a common complication in diabetes mellitus. The association between delayed gastric emptying and overall diabetic complications remains to be studied in detail. We analysed this association.
    MethodsWe performed gastric emptying scintigraphy of Tc-99m-diethylenetriaminepentaacetic acid in 34 patients with diabetes to measure the gastric emptying half-times (T1/2) of the whole stomach (WS), proximal stomach (PS) and distal stomach (DS). We assessed T1/2, diabetic-related factors and complications.
    ResultsThe prevalence of autonomic neuropathy was higher in the group with delayed T1/2 of the WS than in the normal group. Analysis of intima-media thickness (IMT) and ankle brachial pressure index (ABI), which are risk indicators for vascular disorder, showed that IMT of the carotid bulb was greater in the group with delayed T1/2 of the WS than in the normal group (241mm [150-281] versus 140mm [081-208], P=0015). T1/2 of the WS correlated positively with IMT of the carotid bulb (r=0391, P=0027) and negatively with ABI (r=-0389, P=0028). These correlations were mainly attributed to PS and were the same in patients without autonomic neuropathy. In seven of nine patients who received scintigraphy again after diabetic treatment, glycosylated haemoglobin (HbA1c) levels decreased and T1/2 of the WS shortened compared with before treatment.
    ConclusionVascular disorder, among other cofactors such as autonomic neuropathy, could be involved in the pathophysiology of delayed gastric emptying. Medium- to long-term glycaemic control was associated with gastric emptying.

    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.

    A man in his 70's was admitted to our hospital for treatment of a huge hepatocellular carcinoma (HCC) by transcatheter hepatic arterial embolization (TAE). After treatment, anuria occurred, and laboratory examinations revealed a diagnosis of tumor lysis syndrome (TLS). He underwent conservative therapy including hemodialysis, resulting in complete remission of TLS. On the other hand, poor hepatic functional reserve was seen temporarily. After conservative therapy, biochemical markers returned dramatically. TLS is a group of metabolic complications in cancer therapy. It may occur in highly sensitive tumors, resulting from a rapid release of cytoplasmic degradation products of malignant cells. Generally it is rare in the treatment of solid tumors. In the case of TAE for huge HCC, we should keep the possibility of TLS in mind.

    The response rate and overall survival after sorafenib administration in patients with advanced hepatocellular carcinoma are unsatisfactory. We herein present the case of a 65-year-old man with multiple lung metastases of hepatocellular carcinoma. Because the patient had liver cirrhosis of Child-Pugh B accompanied by pancytopenia, sorafenib administration was initiated at a dose of 400 mg daily. Although he received sorafenib for only 21 days, the patient exhibited complete regression of the tumors. There was no clinical evidence of recurrence without the administration of anticancer treatment. It is unique that short-term sorafenib treatment achieved a complete response.

    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.

    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.

    Because of the chronic shortage of liver donors, hepatologists are required to prolong the liver transplant waiting period by preserving the hepatic reserve of scheduled recipients. This study examined the effectiveness of oral branched-chain amino acids (BCAAs), using outcome markers indicating pretransplant hepatic reserve. Fifty-six consecutive eligible patients with Child class A cirrhosis without major complications were randomly assigned to receive oral BCAA granules (12.45 g/day) for least 1 year or no BCAAs. Differences between groups in the Model for End-Stage Liver Disease (MELD) score, Child-Turcotte-Pugh (CTP) score, asialoscintigraphic clearance index (Cl), and complications were examined. Of 50 remaining patients, 27 received BCAAs, and 23 received no BCAAs (mean duration, 3.2 years). The mean annual changes in the MELD score, CTP score, and asialoscintigraphic Cl were smaller in the BCAA group than in the control group (-0.06 +/- 0.23 versus 0.10 +/- 0.40, P = 0.024, 0.06 +/- 0.30 versus 0.30 +/- 0.48, P = 0.037, and 0.00 +/- 0.02 versus 0.02 +/- 0.04, P = 0.040, respectively). The mean annual changes in the serum total bilirubin and the serum albumin in the BCAA group were better preserved than those in the control group (-0.07 +/- 0.20 versus 0.12 +/- 0.18 mg/dL, P &lt; 0.001, and 0.07 +/- 0.13 versus -0.02 +/- 0.19 g/dL, P = 0.005, respectively); other laboratory variables were not significant. The incidence of overall major cirrhotic complications was lower in the BCAA group than in the control group [14.8% (4 of 27 patients) versus 30.4% (7 of 23 patients) at 3 years, P = 0.043]; only ascites was significant individually. In conclusion, early interventional oral BCAAs might prolong the liver transplant waiting period by preserving hepatic reserve in cirrhosis. Liver Transpl 15:790-797, 2009. (C) 2009 AASLD.

    We report a 60-year-old-woman with a huge intracardiac angiosarcoma in whom preoperative F-18 fluorodeoxyglucose (FDG) PET was useful for confirming malignancy of the tumor and determining whether surgery was indicated for it. Her chief complaint was dyspnea. Because she was suspected to have a huge intracardiac tumor on the basis of transthoracic echocardiographic and computed tomography (CT) findings, FDG PET was performed, and the maximum standardized uptake value (SUV) of the tumor was found to be 5.6. Because other tests and SUV level suggested a malignant cardiac tumor, surgical resection of it was attempted. On histopathological examination, the tumor was found to be an angiosarcoma. Our experience with this case indicates that, when dealing with patients suspected to have very large tumors, FDG PET is useful in examination for malignant potential and is indispensable in exploration for distant metastases.

    甲状軟骨の骨化と軟骨浸潤のRI集積の違いを、前方、後方、斜位からの骨シンチグラフィ画像を用いて調べた。喉頭癌もしくは下咽頭癌患者120名(男性104名、女性16名、平均年齢67.8±9.6歳、年齢幅48〜90歳)を対象とした。前方、後方、斜位からの骨シンチグラフィで甲状軟骨への集積を評価した。甲状軟骨への腫瘍浸潤の有無を、手術記録評価に加えて造影CTおよびMRIでの知見と比較することで確認した。甲状軟骨へのRI集積は4種類に分けられた(びまん性集積、極度のびまん性集積、わずかな不均一集積、極度の不均一集積)。びまん性集積患者42名のうち2名、極度のびまん性集積患者18名中1名、わずかな不均一集積患者38名中1名、極度の不均一集積患者22名中17名で、甲状軟骨の腫瘍浸潤がみられた。骨シンチグラフィで甲状軟骨への極度に不均一なRI集積がみられた症例で腫瘍浸潤の程度が最も高かったことから、このRI集積パターンが腫瘍浸潤の指標となると判断した。この判断基準に基づいて診断した場合、陽性的中率、陰性的中率、精度はそれぞれ77%、96%、93%であった。本知見から、頭頸部癌患者で、甲状軟骨の異常RI集積パターンに基づき甲状軟骨の骨化と腫瘍甲状軟骨の識別が可能と考えられた。

    In bone scintigraphy, abnormal RI accumulation in ossified thyroid cartilage is often noted. However, because similar accumulation is also seen in tumor-involved cartilage, distinction between these two lesions is sometimes difficult. We examined the differences in RI accumulation by ossification of the thyroid cartilage and cartilage invasion with anterior, posterior, and oblique views of bone scintigraphy in this study.
    This study included 120 patients (104 men, 16 women; mean age 67.8 +/- 9.6 years; range 48-90 years) with laryngeal or lower pharyngeal carcinoma. The patients had exhibited abnormal accumulation of RI on thyroid cartilage on bone scintigraphy between February 1999 and March 2007. We evaluated accumulation of thyroid cartilage in the anterior, posterior, and oblique views on bone scintigraphy. The presence/absence of tumor invasion of the thyroid cartilage was checked by comparing the findings of enhanced computed tomography and magnetic resonance imaging (MRI) as well as evaluating operative records. RI accumulation in thyroid cartilage was divided into four types (diffuse accumulation, intense diffuse accumulation, slight inhomogeneous accumulation, and intense inhomogeneous accumulation).
    Tumor invasion of thyroid cartilage was noted in 2 of the 42 patients with diffuse accumulation, 1 of the 18 patients with intense diffuse accumulation, 1 of the 38 patients with slight inhomogeneous accumulation, and 17 of 22 patients with intense inhomogeneous accumulation. Because the degree of tumor invasion was highest in cases in which bone scintigraphy revealed intense inhomogeneous accumulation of RI in the thyroid cartilage, we judged this pattern of RI accumulation to be an indicator of tumor invasion. When diagnosis was based on this criterion, positive predictive value, negative predictive value, and accuracy were 77%, 96%, and 93%, respectively (P &lt; 0.0001, Chi-square test).
    The findings of this study suggest that ossification of thyroid cartilage can be distinguished from tumor-involved thyroid cartilage on the basis of the pattern of abnormal RI accumulation in the thyroid cartilage in patients with head/neck cancer.

    71歳男性。左下腹痛を主訴として検査入院した。造影CTにおいて、左骨盤腔に、嚢胞成分と石灰沈着斑点を伴う、大きく不均質に増強された3×5cmの腫瘤を認めた。T2強調MRIでは腫瘍全体が不均質な高信号域として描写され、T1強調造影MRIでは腫瘍は筋肉とほぼ同強度で、病変部は内部に血清成分を内包していることが示唆された。gadoliniumを用いた造影MRIは、腫瘤の存在を明らかにしたが、これらの術前画像診断では、血管肉腫のような悪性疾患の可能性を排除できなかった。術前血管造影では腫瘍周辺の血管分布過多が明らかになり、良性腫瘍である海綿状血管腫が示唆されたが、vascular encasementが認められたため、悪性腫瘍の可能性を排除できなかった。そのため、腫瘍の鑑別にFDG-PETを実施した。185MBq FDGを静注後1時間に、骨盤内スキャンを撮像した。骨盤内腫瘤に不均質な低FDG取込みが認められ、その取込みの程度から、病変は良性であることが示唆された。FDG-PETの結果に基づき手術の延期を検討したが、腫瘍が大きく、破裂の危険性も否定できなかったため、1週間後に手術を施行した。骨盤腔右側の内腸骨動脈と外腸骨動脈への右側腸骨動脈分岐点直下に、6×5.5×3.5cmの腫瘤を確認した。腫瘤には右外腸骨動脈が取り巻き、背面は腰筋に癒着していた。全腫瘍を切除し、右外腸骨動脈の切除と血管再建を行った。組織病理学検査では、腫瘤は良性の海綿状血管腫と診断された。

    A contrast-enhanced mass was revealed by computed tomography and magnetic resonance imaging in the left pelvic cavity of a 71-year-old man. Although the mass appeared to be a cavernous hemangioma, malignancy could not be ruled out. Abdominal angiography was performed but failed to rule out malignancy because it revealed vascular dislocation and encasement. (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) was then performed, and suggested a benign tumor, with a standardized uptake value (SUV) of 1.7. Following this finding, because the tumor was large and rupture could not be ruled out, we decided to perform surgery. The resected tumor was a benign cavernous hemangioma, consistent with the result obtained by FDG-PET.

    Objective Single-photon emission computed tomography (SPECT) using gallium (Ga) has been frequently used for diagnosing head and neck tumors in patients. Although the usefulness of Ga-SPECT is well known, the degree of the increase in diagnostic ability with Ga-SPECT for head and neck tumors has not been reported. We compared the ability of the planar images of Ga scintigraphy, SPECT images of Ga scintigraphy, and CT images to diagnose head and neck primary tumors and neck metastases.
    Methods The subjects of this study were 167 patients with malignant head/neck lesions. For Ga scintigraphy, Ga-67-citrate (74 MBq) was injected via a cubital vein. Planar and SPECT images were taken 72 h after the Ga-67-citrate injection. The rate of detection of the primary lesions was compared first between SPECT and planar images then between SPECT and CT images. The rate of detection for each stage of disease according to the TNM classification was also analyzed.
    Results The rate of detection of primary lesions was 50% with planar imaging and 69% with SPECT. And similarly, regarding the rate of detection of lymph node metastases, there was a significant difference between planar imaging and SPECT. The rate of detection of primary lesions was 70% for both CT and SPECT. At T stage, the rates of detection of primary lesions with each imaging technique were 11% with planar imaging and 39% with SPECT, and 22% with CT for stage T1.
    Conclusions This study revealed the marked superiority of SPECT images over planar images in terms of the ability to detect primary tumors and tumor metastasis to cervical lymph nodes. Furthermore, the primary T1 tumor detection rate of SPECT images was higher than that of CT images. On the basis of these results, the concomitant use of SPECT is highly recommended when Ga scintigraphy is performed to check for malignant head/neck tumors.

    Background/Aims: We simultaneously examined the reservoir function of the stomach as well as emptying by one single assessment for gastric emptying, and investigated their association in patients with functional dyspepsia (FD). Next, we examined the interaction between the association and abdominal symptoms.
    Methodology: Sixty-one FD patients according to the Rome III criteria were recruited for this study. We measured the radioactive changes of the proximal and the whole stomach by the scintigraphy until 120 min, and assessed the reservoir function and the respective half-emptying time. We assessed the symptoms by the previously validated questionnaires.
    Results: Disordered emptying was seen in 55.7% (34/61) of patients, delay in 67.6%(23/34), and acceleration in 32.4%(11/34). Impaired reservoir function was found in 49.2%(30/61) of patients, which had an association with delayed (p=0.025) and disordered (delay+acceleration) emptying (p=0.027). Through the period, the radioactive decrease was dynamic in the normal, but virtually unchanged in the impaired reservoir function group. Symptoms in the motility disordered group tended to be more severe than in the normal group.
    Conclusions: Gastric reservoir function was associated with emptying in FD patients. Abdominal symptoms of FD patients were partly derived from the impairment of coordinated gastric motility.

    Background/Aims: The purpose of this study was to validate the usefulness of positron emission tomography with fluorine-18-fluoiodeoxyglucose (FDG-PET) in predicting degree of malignancy and prognosis, evaluated in terms of Japan Integrated Staging (JIS) score, in cirrhotic patients with hepatocellular carcinoma (HCC).
    Methodology: FDG-PET was performed in 50 patients with HCC. The activity within regions of interest placed over tumors was measured, and standardized uptake values (SUVs) were calculated by dividing the tissue activity by injected dose of radioactivity per unit body weight. SUV ratio (SUVR) was expressed as tumor-to-nontumor ratio of SUV. Patients were allocated to 3 groups of similar size: group A, SUVR &lt;= 51.1; group B, 1.1 &lt; SUVR &lt; 1.6; and group C, 1.6 &lt;= SUVR.
    Results: SUVR significantly correlated with tumor node metastasis stage score (p &lt; 0.001) or JIS score (p=0.022). Survival rate in SUVR group C Was significantly lower than that in group A (p &lt; 0.001), and close to being significantly lower than that in group B. On multivariate analysis, JIS scores 2 and &gt;= 3, SUVR group C were significantly related to survival (All p &lt; 0.05).
    Conclusions: SUVR was well associated with a tumor staging which is the factor of JIS score and with survival, and indicated malignancy and prognosis of patients especially with high-grade HCC.

    We report a 44-year-old-man with a biliary-gastric fistula in whom Tc-99m Sn-N-pyridoxyl-5-methyltryptophan (PMT) hepatobiliary scintigraphy was useful in determining indications for surgery. A small orifice suspected to be the opening of a biliary-gastric fistula was found on upper endoscopy, and an anatomic structure suspected to be a gastrobiliary fistula was detected on magnetic resonance cholangiopancreatography (MRCP). Tc-99m PMT hepatobiliary scintigraphy revealed continuous flow of bile into the stomach through the fistula. Flow of bile into the stomach through a fistula can cause gastric cancer, and is therefore indicated for surgical treatment. Tc-99m PMT hepatobiliary scintigraphy was useful in determining the indications for surgery.

    症例は健康診断時に肝機能異常が認められた66歳の男性で、腹部超音波検査では膵臓頭部に直径4cmの腫瘤と両側肝内胆管の拡張が観察された。腫瘍マーカーは正常範囲で、磁気共鳴胆道膵管造影、MRI検査及びダイナミックCTスキャン所見から、自己免疫性膵炎(AIP)が疑われた。フルオリン-18-フルオロデオキシグルコース陽電子放出型断層撮影(FDG-PET)を実施したところ、膀胱壁及び総胆管底部に異常な蓄積を認めた。膵臓に腫瘍を示す蓄積は認められなかった。血中γ-グロブリン、IgG及びIgG4レベルは正常範囲内であったことから、AIPと診断した。AIPを伴う硬化性胆管炎(SC)症例では、原発性SC、膵癌及び胆管癌との鑑別が困難な場合がある。FDG-PETは膵臓外部の病変の評価及びAIP治療に対するステロイド療法の反応の観察に有用である。

    The extrapancreatic bile duct lesions in autoimmune pancreatitis are termed sclerosing cholangitis (SC with AIP), which is known to complicate AIP somewhat more frequently than other extrapancreatic lesions. In cases of SC with AIP, differentiation from primary SC, pancreatic cancer, and bile duct cancer is often difficult. In our patient, pancreatic cancer had to be ruled out at admission, given the findings of obstructive jaundice, pancreatic duct stenosis, and swelling of the pancreas. Fluorine-18-fluorodeoxyglucose positron emission tomography was useful in checking for the presence of extrapancreatic lesions, including SC, and was also useful in the evaluation of the response to steroid therapy for following the course of AIR

    We report a 67-year-old woman with systemic lupus erythematosus and systemic disseminated tuberculosis affecting the femoral trochanteric bursae, a site rarely affected by tuberculosis. For quantification of the inflammation with gallium-67 scintigraphy, we calculated the radioisotope Count ratio in the most inflamed areas, the right lateral thorax and bursa of the right greater trochanter. Systemic scanning with this modality allowed evaluation of the extent of lesions and simple quantitative determination of the severity of inflammation, yielding information useful for the follow-up of the patient during the course of tuberculosis treatment.

    Objective: Fluorine-18-fluorodeoxyglucose positron emission tomography (FDG-PET) is sometimes used as a means of follow-up after diagnosis and treatment of cancers of the head and neck region. The present study was undertaken to evaluate the ability of FDG-PET to detect local residual tumor after treatment of laryngeal cancer. Methods: Thirty-six patients with laryngeal cancer underwent FDG-PET before and after initial treatment. Of these patients, 20 received FDG-PET before treatment and 28 received it after treatment. The relationship between standardized uptake values (SUV) and the presence or absence of local residual tumor was investigated by setting the cut-off value of the SUV using the receiver operating characteristics (ROC) curve. Results: When the pre-treatment SUV threshold for laryngeal cancer was set at 7.20, the detection of local residual tumor after treatment using FDG-PET had a sensitivity of 77.78%, specificity of 81.82%, false positive rate of 18.18%, false negative rate of 22.22%, accuracy of 80% and a p value of 0.02. When the post-treatment SUV threshold for the larynx was set at 3.35, the test had a sensitivity of 93.75%, specificity of 91.67%, false positive rate of 8.33%, false negative rate of 6.25%, accuracy of 92.86% and a p value of 0.0001. Conclusions: FDG-PET was found to be useful for determining the presence of local residual tumor after treatment of laryngeal cancer.

    BACKGROUND: Dementia of Alzheimer type (DAT) has been diagnosed objectively by using single photon emission tomography (SPECT). Donepezil hydrochloride (donepezil) is available for the symptomatic treatment of DAT. In a quantitative evaluation of therapeutic response in DAT, to compare with regional cerebral blood flows (rCBF) of various lesions before and after treatment, uptake in some sorts of cerebral regions of interests (ROIs) were used to be measured. But ROI analysis has problems such as poor reproducibility and lack of objectivity. The aim of this study was to investigate the evaluation of therapeutic response by three-dimensional stereotaxic ROI template (3DSRT), fully automated ROI analysis software, which can objectively estimate rCBF. METHODS: SPECT studies and Alzheimer's Disease Assessment Scale Japan cognitive Subscale function test ADAS-Jcog, as recognitive function test were performed for 22 patients (16 females, 6 males mean age = 73.6 years) who were diagnosed as DAT. On 3DSRT, we compared ratios of the rCBF values of the parietal lobes, temporo-occipital lobes, hippocampus, corpus callosum and the frontal lobes/cerebellar hemispheres before and after medical treatment. To determine a cut-off number of areas exhibiting improved blood flow optimal as an indicator of improvement in cognitive function in response to treatment, receiver operating characteristics (ROC) analysis of number of areas improved blood flow was performed. RESULTS: The number of cases exhibiting changes in cognitive function was greatest when the cut-off number of areas exhibiting improved blood flow was set at 5. CONCLUSIONS: The possibility of evaluation of therapeutic response to Donepezil in patients with DAT using 3DSRT was thus demonstrated by our study.

    Objective: Because thickening of the gallbladder wall is observed not only in patients with gallbladder cancer but also in those with benign diseases such as chronic cholecystitis and gallbladder adenomyosis, it is difficult to distinguish between benign and malignant gallbladder wall thickening by conventional techniques of diagnostic imaging such as computed tomography (CT), magnetic resonance imaging (MRI), and abdominal ultrasonography (US). In the present study, we attempted to distinguish between benign and malignant gallbladder wall thickening by means of fluorine-18-fluorodeoxyglucose (FDG)-Positron emission tomography (PET). Methods: FDG-PET was performed in 12 patients with gallbladder wall thickening detected by CT or US, to determine whether it was benign or malignant. Emission scans were taken, beginning 45 minutes after intravenous administration of FDG, and SUV was calculated as an indicator of glucose metabolism. Results: Of the 12 patients, 4 showed positive uptake of FDG in the gallbladder wall. Of these 4 patients, 3 had gallbladder cancer. The remaining one, who had chronic cholecystitis, had false-positive findings. The other 8 patients had negative uptake of FDG in the gallbladder wall. Two of these 8 underwent surgical resection, which yielded a diagnosis of chronic cholecystitis. The other 6 patients exhibited no sign of gallbladder malignancy and have been followed without active treatment. Conclusions: FDG-PET appears able to distinguish between benign and malignant gallbladder wall thickening.

    Background: Atrophic and inflammatory changes in the gastric mucosa are commonly observed in Japanese patients with functional dyspepsia. However, detailed data regarding the correlation between the severity of these changes and the symptoms of functional dyspepsia are not available. Aim: To evaluate grading scales of gastric atrophy and inflammation, severity of clinical symptoms, and gastric emptying in patients with functional dyspepsia. Methods: Ninety-three patients with dyspepsia were enrolled. The severity of gastric atrophy was graded through serological and histological examination, and gastric inflammation was evaluated histologically. Clinical symptoms were evaluated on the Gastrointestinal Symptoms Rating Scale, including subscales for abdominal pain, acid reflux, diarrhoea, indigestion and constipation. Gastric emptying half-time was measured using a radioisotope technique. Results: Helicobacter pylori infection and gastric inflammation influenced neither clinical symptoms nor gastric emptying time. However, a correlation was observed between gastric atrophy as graded by serological examination and indigestion (R = 0.31, P = 0.01). Histological examination also showed a correlation between gastric atrophy and abdominal pain and indigestion (R = 0.31, P = 0.04 and R = 0.35, P = 0.02 respectively). Conclusion: Gastric atrophy associated with H. pylori infection may be partly responsible for the clinical symptoms experienced by patients with functional dyspepsia. © 2006 The Authors.

    A 53-year-old man with a history of nausea and elevated liver functions presented to our clinic. A CT scan showed a small tumor in the right lobe of the liver. Fluorine-18-fluorodeoxyglucose (F-18-FDG) positron emission tomography confirm abnormal metabolic activity with a high standardized uptake value of 7.3 in the lesion. These findings could indicate a malignancy such as well-differentiated hepatocellular carcinoma or cholangiocarcinoma, or a benign lesion such as hepatic abscess. He was diagnosed by histopathological examination as having an epithelioid granuloma with many inflammatory cells. This is the rare report of hepatic inflammatory pseudotumor featuring markedly increased F-18-FDG uptake.

    We report two cases of poorly differentiated squamous cell carcinoma of the left maxillary sinus. Both patients had a similar clinical course and similar imaging findings. However, FDG uptake by the 2 lesions was very different. The SUVs of the tumor lesions of patient I and 2 were 20.67 and 7.56, respectively. Histopathologically, hematoxylin and eosin (H&E) stained sections (X200) were packed with tumor cells, with many more inflammatory cells seen in patient 1. When dealing with cases of carcinoma of the head neck region where tumors are often accompanied by inflammation, we should bear in mind that FDG uptake by tumors is strongly influenced by the activity and timing of inflammation within the tumor lesions.

    AIM: To examine the correlation between the porto-systemic hypertension evaluated by portal shunt index (PSI) and life-threatening complications, including hepatocellular carcinoma (HCC), liver failure (Child-Pugh stage progression), and esophagogastric varices.
    METHODS: Two hundred and twelve consecutive subjects with HCV-related cirrhosis (LC-C) underwent per-rectal portal scintigraphy. They were allocated into three groups according to their PSI: group I, PSI &lt;= 10%; group II, 10%&lt;PSI&lt;30%; and group III, 30%&lt;= PSI. Of these, selected 122 Child-Pugh stage A (Child A) subjects were included in analysis (a mean follow-up period of 5.9 +/- 5.4 years, range 6 mo-21 years).
    RESULTS: No significant correlation between PSI and cumulative probability of HCC incidence was observed. Cumulative probability of Child A to B progression was tended to be higher in group III than in group I, and significantly higher in group III than in group II (62% vs 34%, 62% vs 37%; P = 0.060, &lt;0.01; respectively). Cumulative probability of varices tended to be higher in group III than in group I (31% vs 12%, P = 0.090). On multivariate analyses, significant correlation between PSI and Child A to B progression was observed, and no significant correlation between PSI and HCC incidence or varices progression was observed.
    CONCLUSION: Patients with LC-C of Child A will progress to Child B rapidly after their PSI reaches 30% or higher. PSI can be used to predict occult progressive porto-systemic shunting and liver failure non-invasively. It indicates that PSI may play an important role in follow-up of the porto-systemic hypertension gradient for outpatients with LC unlike hepatic venous catheterization.

    The authors report unusual splenic accumulation of Tc-99m hydroxymethylene diphosphonate (HMDP) on bone scintigraphy of a patient with alcoholic cirrhosis of the liver. Laboratory studies showed hemolytic anemia and hemochromatosis resulting from alcohol abuse, both of which are thought to be related to the diffuse splenic uptake observed. When diffuse splenic accumulation by Tc-99m HMDP is seen, the existence of alcoholic hepatopathy might be considered.

    Small cell carcinoma (SmC) of the esophagus is rare, and is sometimes impossible to detect by macroscopic inspection using an endoscope or histological examination of biopsied specimens. A 73-year-old man received F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) to evaluate the response to radiofrequency thermal ablation therapy for lung cancer. FDG-PET showed abnormal accumulation in the posterior mediastinum. Endoscopy disclosed ulcerous lesions with marginal elevation in the middle segment of the esophagus, but the biopsy specimen taken concurrently was not malignant histologically. FDG-PET, performed two months later, revealed abnormal accumulation in the suspect area, and the extent of accumulation was wider than previously. Histological examination of the specimen biopsied during the endoscopy led to a diagnosis of SmC. FDG-PET thus proved useful in the early detection of SmC.

The existence of RBC antibodies, as a result of the recent blood transfusions in this patient, was one of the causes of the poor labeling. In radionuclide bleeding studies with patients with recent blood transfusion, Tc-99m HSA-D must be chosen instead of Tc-99m RBCs in vivo.

    Hepatic functional reserve can be evaluated in a noninvasive way by scintigraphy with Tc-99m-DTPA-galactosyl human serum albumin (Tc-99m-GSA). We monitored hepatic functional reserve in patients with chronic hepatitis and cirrhosis using scintigraphy with Tc-99m-GSA to determine the natural course of changes in their hepatic functional reserve. Computer acquisition of gamma-camera data was started before the injection of 185 MBq of Tc-99m-GSA and was stopped 20 min later. Time-activity curves were generated from ROI for the heart and liver. A receptor index and index of blood clearance were calculated from radioactivity in the heart and liver. Scintigraphy with Tc-99m-GSA was performed in 12 healthy subjects, 86 patients with chronic hepatitis, and 226 patients with cirrhosis. Seventy-two patients (23 with chronic hepatitis, 32 with cirrhosis in Child-Pugh stage A, 15 in stage B, and 2 in stage C) were examined at least twice with 12-72 months intervening. The receptor index was lower for more severe disorders, decreasing in the order of chronic hepatitis and cirrhosis in stages A, B, and C. The index of blood clearance was higher for more severe disorders, increasing in the order of chronic hepatitis and cirrhosis in stages A, B, and C. The mean annual change in the receptor index with chronic hepatitis was -0.0007, that with cirrhosis in stage A was -0.0023, and that with cirrhosis in stage B or C was -0.0117. The difference between the median annual change with cirrhosis in stage B or C and that with chronic hepatitis or cirrhosis in stage A was not significant (P = 0.064 and 0.251, respectively). The mean annual change in the index of blood clearance with chronic hepatitis was 0.0018, that with cirrhosis in stage A was 0.0060, and that with cirrhosis in stage B or C was 0.0330. The difference between the median annual change in the index of blood clearance with cirrhosis in stage B or C and that with chronic hepatitis or cirrhosis in stage A was significant (P = 0.004 and 0.007, respectively). Hepatic receptor imaging with Tc-99m-GSA could be used to noninvasively evaluate the hepatic reserve of various liver diseases. Changes in hepatic functional reserve were not steady; it decreased gradually as disease advanced from chronic hepatitis to cirrhosis in Child-Pugh stage A, and decrease rapidly after development of stage B cirrhosis.

    We examined the difference between early cirrhotic patients with lower branched-chain amino acids (BCAA) to tyrosine ratio (BTR) (&lt; 4) and higher BTR (&gt; 4) in portal circulation using per-rectal portal scintigraphy with technetium-99m pertechnetate. Forty patients with Child-Pugh grade A cirrhosis and serum albumin level between 3.5 and 3.9 g/dl were enrolled in this study. Sixteen patients were infected with HBV and 24 with HCV. Thirteen patients had BTR &lt; 4.0 and 27 had BTR &gt; 4.0. Shunt index (SI) obtained through per-rectal portal scintigraphy was significantly correlated with BTR (r = -0.558, P &lt; 0.0002). ICGR-15 was most strongly correlated with BTR among six parameters representing liver reserve capacity. The mean SI of patients with BTR less than 4 (38.4+/-28.0%) was significantly higher than that of patients with BTR greater than 4 (17.3+/-14.3%) (P = 0.0388). The mean concentration of serum BCAA did not significantly differ between the two groups, but the mean concentration of serum tyrosine in the patients with BTR &lt; 4 was significantly higher than that in the patients with BTR &gt; 4 (P = 0.0081). These results suggested that the increase in porto-systemic shunt caused tyrosine passing through liver and stagnating in the serum, as a result of which BTR fall in early cirrhosis. In conclusion, decrease of blood flow through liver and increase in porto-systemic shunt might be partly responsible for deterioration of BTR in early cirrhosis. (C) 2003 Elsevier Science B.V.

    Objective: Skeletal muscle is said to compensate for the decreased ammonia metabolism in patients with cirrhosis. Branched-chain amino acids (BCAA) are being used as a treatment for hyperammonemia, and are believed to decrease blood ammonia by consumption of BCAA in skeletal muscles. We examined ammonia metabolism of the skeletal muscles in patients with liver cirrhosis after administration of BCAA using N-13-ammonia positron emission tomography (PET). Methods: The subjects were patients with compensated or decompensated liver cirrhosis. PET studies were performed before and 2 hours after injection of BCAA. Serial dynamic PET scans (2 min x 10 frames) were started simultaneously with N-13-ammonia injection. The standardized uptake value (SUV) of both thighs was calculated. Results: In the patient with compensated liver cirrhosis, there was little difference in the rate of increase in SUV before to after administration of BCAA. However, in the patient with decompensated liver cirrhosis, the rate of increase in SUV after administration was higher than that before administration of BCAA. Conclusion: Ammonia metabolism in the muscle of patients with liver cirrhosis could be examined noninvasively under physiological conditions using N-13-ammonia PET. The muscles were found to metabolize ammonia partially, and the role of this contribution to metabolism of ammonia in patients with decompensated liver cirrhosis is particularly important.

    Background. Preoperative percutaneous transhepatic portal vein embolization (PTPE) increases the safety of liver resection and improves the outcome after surgery for hepatocellular carcinoma. Scintigraphy with Tc-99m-galactosyl human serum albumin (GSA) causes specific binding to viable hepatocytes and serves as an index of liver function.
    Materials and methods. Tc-99m-GSA scintigraphy was performed before and 2 weeks after PTPE of the right portal vein in 16 patients. The total receptor index, reflecting overall liver function, right receptor index (right lobe), and left receptor index (left lobe) were calculated.
    Results. After PTPE, the proportion of the volume of the nonembolized lobe (left lobe) increased (P = 0.0002). The total receptor index slightly decreased after PTPE (P = 0.090), the right receptor index decreased (P &lt; 0.0001), and the left receptor index increased (P &lt; 0.0001). The average increase rate in the left receptor index was 30% of the pre-PTPE value. In 2 patients with portal hypertension (greater than or equal to30 cm H2O) after PTPE, the left receptor index did not change. In 4 patients whose left receptor index after PTPE (including the 2 patients with portal hypertension) was &lt;0.35, right lobectomy was not performed.
    Conclusions. Tc-99m-GSA scintigraphy demonstrated that PTPE induces a shift in hepatic function from the embolized part to the nonembolized part of the liver. PTPE of the right portal vein increases the hepatic functional reserve of the left lobe as well as its volume. The changes in Tc-99m-GSA uptake following PTPE may predict the response to liver resection. (C) 2002 Elsevier Science (USA).

    Gastric duplications are relatively rare, and communication with the gastric lumen is extremely rare. A 67-year-old man was referred to our hospital because of recurrence of epigastric pain and fullness. An upper gastrointestinal contrast study revealed a double compartment stomach, with gastric duplication starting at the esophagogastric junction outside the greater curvature. Computed tomography of the stomach with gastrografin as contrast demonstrated complete communication of the gastric duplication and primary stomach. The patient was diagnosed with complete gastric duplication. Gastric emptying scintigraphy with Tc-99m diethyltriamine pentaacetic acid was performed. Test meal entered the primary stomach and duplication cyst simultaneously, and radioactivity in the primary stomach decreased linearly and gastric emptying was not delayed. In the duplication cyst, about 70% of the food that entered the cyst once was immediately evacuated from it, but the remaining 30% remained in the cyst for a long time. Gastric emptying of the primary stomach was not affected by formation of the duplication cyst.

    There have been a number of reports of gastric emptying in cirrhosis, all with unconfirmed results. Moreover, the mechanism for delayed emptying in cirrhotic patients is unclear. We evaluated gastric emptying in patients with chronic hepatitis and cirrhosis by means of gastric emptying scintigraphy. Methods: The subjects were 18 normal controls and 75 patients with chronic viral hepatitis (50 patients had chronic hepatitis and 25 patients had cirrhosis). Tc-99m diethyltriamine pentaacetic acid labeled solid meals were used to evaluate gastric emptying; the half-time (T 1/2) of which was calculated. Digestive symptom scores were determined at the time of gastric emptying tests. Results: Fourteen (28%) of 50 patients with chronic hepatitis and 16 (64%) of 25 patients with cirrhosis had delayed gastric emptying. T 1/2 in patients with cirrhosis was significantly higher than that in normal controls and patients with chronic hepatitis (p = 0.0001 and 0.0003, respectively). The difference between T 1/2 in patients with chronic hepatitis and that in normal controls was not significant. On regression analysis, two indices-the serum albumin level and platelet count-were found to be significantly related to delayed gastric emptying. Conclusions: Gastric emptying was more delayed in cirrhotic patients than in those with chronic hepatitis and normal controls. Delayed gastric emptying may be related to liver function and portal hypertension.

    We analyzed 616 chronic hepatitis C patients who were treated with DAAs from Sep 2014 to Aug 2016 and eight acute hepatitis C patients after May 2007 in our hospital. 372 patients (60.4%) identified their infection routes via a blood transfusion, surgery, intravenous drug use (IDU), family history, and tattooing in 189,279, 30, 18, and 24, respectively. There were no patients who were reinfected with HCV during the observation period of 34 months. Infection via IDU and tattooing still have a possibility for reinfection after SVR. These were predominant routes in young, male, and genotype 2 patients. In addition, patients who were lost to follow-up treatment showed the same backgrounds. Our data indicated that they may be candidates in a high risk group of HCV reinfection. We should observe and educate them more intensely.

    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.

    A 72-year-old female was diagnosed as having chronic hepatitis C 16 years before, and her anti-viral therapies with interferon were unsuccessful. She suffered from fever, edema and purpura for two months before admission. Then, she was diagnosed with hepatitis C virus-associated mixed cryoglobulinemic vasculitis. After treatment with daclatasvir/asunaprevir, her clinical symptoms improved rapidly and she had a sustained virologic response. Since late 2013, several novel DAAs have been approved by the FDA. Interferon-free regimens that combine such novel DAAs are highly effective for the treatment of chronic HCV infection. To our knowledge, this is the first published report documenting the efficacy of daclatasvir/asunaprevir in a patient with HCV-associated mixed cryoglobulinemic vasculitis.

    通院中のNAFLD 42名、NASH 58名、対照群として健常者57名において、生活習慣病の保健指導支援ソフトウェア&quot;ヘルッチェ&quot;(スズケン)や、生活習慣記録機ライフコーダ(スズケン)などを用いて、日常の生活習慣を分析した。結果、NAFLD/NASHでは健常者に比べ、体組成的に脂肪量が多く握力が低下している傾向が見られた。この傾向はNASH群においてより顕著であった。食習慣については、健常群と比して総摂取カロリーの過剰や、PFC比の偏りは見られず、食習慣改善に対するステージモデルにおいても、実行期・維持期の割合が有意に高く、意識して改善している傾向が見られた。しかし男性では健常者に比して魚介類の摂取量が少ないことなどから、摂取食品、食材にまで気を配った食事指導が望まれた。運動習慣について、身体活動量や歩数が低値を示し、生活活動強度が低い傾向が見られた。男女ともに、NAFLD/NASH群は自らの病識も明確で、食習慣は改善意識が高く改善傾向が見られたが、生活活動強度/運動習慣においては改善の余地があった。NAFLD/NASH患者には、食事指導のみならず、生活活動強度の向上、無理のないエクササイズ実施、継続など、包括的な生活改善支援が望まれる。(著者抄録)

    症例は70歳代、男性。肝細胞癌に対する経カテーテル的肝動脈塞栓術施行目的で入院した。術後に腫瘍崩壊症候群を発症したが、血液透析にて軽快した。また、一時的に肝機能障害および肝予備能低下を認めたものの保存的治療にて軽快した。巨大な肝細胞癌に対する肝動脈塞栓術後には、常に腫瘍崩壊症候群や肝予備能低下がおこる可能性に留意すべきと思われたため、若干の文献的考察を加え報告する。(著者抄録)

    症例は69歳、男性。C型肝硬変・肝細胞癌(HCC)に対する治療を繰り返していたが、増悪したため、ミリプラチン動注療法目的で入院となった。第0病日、HCCに対してミリプラチン動注療法(計102mg)を施行した。第8病日頃より、咳嗽・喀痰が出現し、第17病日の胸部CTでは両側肺野のびまん性擦りガラス状陰影を認めた。PaO2 53Torrと著明な低酸素血症を認め、急性呼吸不全にて人工呼吸器管理とし、ステロイドパルス療法(メチルプレドニゾロン1g/日3日間)を開始した。その後徐々に呼吸状態は改善し、第24病日、人工呼吸器より離脱した。第53病日の胸部CTでは肺炎像は著明に改善していた。血液検査・喀痰培養・気管支肺胞洗浄などの結果から感染による肺炎は否定的であり、ミリプラチンによる薬剤性肺障害の可能性が高いと考えられた。(著者抄録)

    PET(positron emission tomography)は腫瘍の代謝面での評価を行うことにより,CTやMRIなど従来の画像診断に比べ治療効果を早期にとらえることができる.PETの利点は客観的指標であるSUV(standardized uptake value)を用いることにより腫瘍を数量的に評価できること,腫瘍の全身転移を評価できる点である.PETの腫瘍診断に関しては,糖代謝を評価するフルオロデオキシグルコース(FDG)が広く用いられているが,肝細胞癌の約半数において偽陰性を示す.しかしリン脂質代謝や脂肪酸代謝を反映するPET製剤を用いることによりPET陰性癌の診断が可能である.今後これらのPET製剤を組み合わせることにより,肝細胞癌に対する化学療法の効果判定にPETの果たす役割は大きくなっていくと考えられる.(著者抄録)

    早期肝硬変から開始する経口分枝鎖アミノ酸顆粒製剤(BCAA)療法により、ドナー決定までの待機時間の延長が可能かを検証した。統計解析の対象はBCAA顆粒群27例、対照群23例で、平均観察期間は3年2ヵ月であった。割付けは無作為に行った。1)本検討に用いたthe Model for End-Stage Live Diseaseスコア、Child-Turcott-Pughスコア、アシアロシンチグラフィによるクリアランスインデックスの年平均変化率の平均値±標準偏差は、BCAA群が対照群よりも有意に低かった。2)血液性化学検査の主な肝予備能指標の年平均変化率はBCAA群が対照群よりも総ビリルビン値が有意に低く、血清アルブミン値が有意に高かった。3)主要な肝硬変合併症の累積発症率はBCAA群が対照群よりも有意に低かった。4)肝細胞癌、腹水、胃・食道静脈瘤、肝性脳症の個々の累積発症率は腹水だけがBCAA群において有意に低かった。5)食道静脈瘤の発症率はBCAA群において境界域の有意差で低かった。

    Functional Dyspepsia(FD)におけるH.pylori感染と胃内部位別排出能への影響と消化器症状との相関性を検討した.対象は腹部不快感,腹部膨満感などを主訴に受診したFD患者57名(H.pylori陽性群35名・平均59.5歳,陰性群22名・平均47.8歳)であった.FD全体の胃排出能は健常人に比し遅延しており,タイプ別では運動不全型,非特異型で遅延を認めた.H.pylori陽性群と陰性群の間で排出能に有意差はなかった.FD全体では,胃近位側弛緩反応群(C/T比&gt;0.5)とH.pylori陽性群との相関性は認めななったが,運動不全型ではH.pylori陽性群で胃適応性弛緩が陽性で,H.pylori陰性群では胃適応性弛緩が損なわれる可能性を認めた.H.pylori感染に伴う胃粘膜萎縮と消化不良症状に正の相関を認めたが,それ以外に相関性は認めなかった.FD全体の病態生理の中では,H.pylori感染の意義は比較的少ないと考えられた
