Abstract Lifestyle modification is the standard of care for nonalcoholic fatty liver disease (NAFLD) patients. We aimed to investigate the efficacy of a short‐term lifestyle modification program in the disease course of Taiwanese nonalcoholic steatohepatitis (NASH) patients with paired biopsies. All patients received a 6‐month, strict multidisciplinary program of lifestyle modifications led by physicians, dieticians, and nursing staff. The histopathological and clinical features were assessed. The endpoints were normalization of transaminase levels, metabolic parameters, a decrease in the NAFLD activity score (NAS) ≥1, and a decrease in the fibrosis stage ≥1. We also aimed to elucidate the predictors associated with disease progression. A total of 37 patients with biopsy‐proven NASH were enrolled. The normalization of transaminase levels increased from 0% to 13.5%. There were also significantly increased proportions of patients with normal total cholesterol, triglyceride, and hemoglobin A1c levels. Fifteen (40.5%) patients had an increased NAS ≥1, whereas 10 (27.0%) patients had NAS regression. Twelve (32.4%) patients had increased fibrosis ≥1 stage. Only 2 (5.4%) patients experienced fibrosis regression. A high fasting plasma glucose (FPG) level was associated with NAS progression. Older age and higher transaminase and FPG levels were factors associated with fibrosis progression. Seven (18.9%) patients achieved a body weight reduction >3%, and 4 (57.1%) of them experienced NAS regression. No significant effect of weight reduction on the progression of fibrosis was observed. The short‐term lifestyle modification program significantly decreased liver enzymes and metabolic parameters in NASH patients. A more precise or intensive program may be needed for fibrosis improvement.

Abstract Favorable prognostic factors and therapeutic strategies are important for patients with single large hepatocellular carcinoma (HCC). This retrospective study aimed to investigate the prognostic factors in patients with single large (≥5 cm) HCC with Child‐Pugh (CP) class A patients and to recommend therapeutic strategies. Overall, 298 HCC patients with single and large (≥5 cm) tumors with CP class A, but without distant metastasis and macrovascular invasion were included, and their clinicopathological data, overall survival (OS), and progression‐free survival (PFS) were recorded. OS and PFS was analyzed by the Kaplan–Meier method and Cox regression analysis. Propensity score matching (PSM) analysis was performed. The 298 HCC patients were 79.2% male and median age of 64 years. For the initial treatment, surgical resection (SR) and transarterial chemoembolization (TACE) was 50.8% and 49.2%, respectively. The OS and PFS were significantly higher in patients receiving SR than those receiving TACE before and after PSM. Furthermore, in multivariate analysis, cirrhosis (Hazard ratio [HR]: 2.04; 95% confidence interval [CI]: 1.35–3.03, p

Abstract The majority of patients undergoing methadone maintenance treatment (MMT) are neither examined nor treated for hepatitis C virus (HCV) infection. We aimed to evaluate an integrated referral model in the management of HCV among MMT patients. This retrospective study included 390 HCV‐infected MMT patients between April 2015 and May 2017. Patients who tested positive for HCV antibodies were referred to a liver clinic by MMT case managers or psychiatrists. Patients who agreed to receive anti‐HCV treatment were treated with pegylated interferon and ribavirin. The rate of patient engagement at a liver clinic increased from 14.1% to 58.2% after integrated care. Multiple logistic regression analysis showed that higher education level (odds ratio [OR], 1.62; 95% confidence interval [CI], 1.01‐2.60) and elevated ALT level (OR, 4.30; 95% CI, 2.70‐6.85) were independently associated with patients who accepted referral. Active drug use (OR, 0.52; 95% CI, 0.31‐0.85) was inversely associated with referral acceptance. Of the 112 patients who met the criteria for anti‐HCV therapy, 66 (58.9%) were treated with pegylated interferon and ribavirin. Finally, the rate of treatment completion and sustained virological response (SVR) was 65.2% and 54.5%, respectively, among the 66 patients. Treatment completion (OR, 39.67; 95% CI, 7.80‐201.62) was found to be the only independent factor associated with SVR achievement. Although integrated care by psychiatrists and hepatologists significantly increased the rates of engagement and acceptance of antiviral treatment for HCV‐infected MMT patients, only a minority of MMT patients achieved successful treatment.

There is a strong association between hepatitis C virus (HCV) treatment efficacy and the interleukin (IL)-28B gene. However, the IL-28B variant's distribution and potential role in the therapeutic response are not well established in Taitung, a racially diverse county in Taiwan. Here, we investigated the distribution pattern of IL-28B rs8099917 and its influence on treatment efficacy. In this retrospective study, we enrolled 180 patients who had been treated with pegylated-interferon plus ribavirin. Patients' general information, virological characteristics, IL-28B status, laboratory results, treatment course, and outcome were analyzed. Of the patients enrolled, 56.7% were male, with a mean age of 54.11 years. A total of 24.4% of the population were indigenous people. The majority of patients had the favorable IL-28B polymorphism (rs8099917 TT/TG/GG: 94.4%/5.6%/0%). The proportion of patients with the TT genotype seemed to be higher in indigenous patients. The rate of sustained virological response (SVR) among included patients was 73.0%. Univariate analysis showed that genotype non-1, patients achieved rapid virological response (RVR), lower body mass index (BMI), and lower baseline HCV viral load were significantly associated with SVR. Multivariate analysis revealed that BMI

Lamivudine, telbivudine, and entecavir are the first-line drugs covered by the Taiwan National Health Insurance as 3-year treatments for patients with chronic hepatitis B virus (HBV), but the optimal treatment duration of each remains unclear. We aimed to detect HBV treatment-cessation durability, and compare the predictors in patients with and without clinical relapse. In this retrospective cohort study, 210 patients with chronic HBV who tested hepatitis B e-antigen positive or hepatitis B e-antigen negative were treated for 3 years with a nucleos(t)ide analogue. Of these, 102 patients continued therapy after 3 years, while 88 patients stopped treatment and were followed for 1 year due to financial difficulties. Efficacy was assessed in terms of alanine aminotransferase (ALT) level normalization, HBV DNA clearance, virus breakthrough, clinical relapse, and liver decompensation. The durability predictors were evaluated by host factors, HBV DNA, and drug differences. Eighty patients (14 on lamivudine, 19 on telbivudine, and 47 on entecavir) were recruited. There was no difference in clinical-relapse rate among lamivudine, telbivudine, and entecavir (35.7% vs. 36.8% vs. 31.9%, respectively; p = 0.916), and liver decompensated hepatitis was absent. In baseline clinical characteristics, there were no differences between the clinical-relapse and nonrelapse groups in age, sex, cirrhosis, prior treatment, HBV DNA, pretreatment ALT, or hepatitis B e-antigen (HBeAg). The mean 3rd year serum ALT level differed significantly between clinical-relapse and nonrelapse patients (37.5 U/L vs. 27.7 U/L, respectively; p = 0.044). The 3-year nucleos(t)ide analogue off-treatment in patients with chronic HBV delivered according to the Taiwan National Health Insurance guidelines had an overall 33.8% 1-year clinical-relapse rate without any decompensated hepatitis flare-ups.

The genotypes of hepatitis C virus (HCV) are associated with the therapeutic response. The racial diversity of Taitung, Taiwan is heterogeneous and a distinguishing feature; how such racial differences influence the genotype distribution and treatment outcome has not been well studied. The objective of this study is to elucidate the HCV genotype distribution in southeastern Taiwan and to analyze the racial differences influencing genotypes and clinical implications. In this retrospective cohort study, we included 343 patients who had been treated with peginterferon-alpha plus ribavirin. The predominant HCV genotype in the southeastern area was type 1 (43.7%), followed by type 2 (37.0%). The proportion of patients mixed with genotype 1 was lower in indigenous vis-à-vis nonindigenous groups (46.1% and 60.2%, p = 0.02). The prevalence of genotype 6 (5.2%) seems higher than in the general population of Taiwan and showed no difference between indigenous and nonindigenous people. The sustained virological response rate was higher in patients without genotype 1, low baseline HCV RNA (≤ 400,000 IU/mL), and in patients who achieved rapid virological response. Racial differences did not influence the therapeutic response. In this retrospective study, the proportion of HCV genotype 6 appeared slightly higher in southeastern areas than in the general population in Taiwan. The prevalence of genotype 1 in indigenous people was statistically lower than in nonindigenous people. Sustained virological response rate did not show any significant difference between indigenous and nonindigenous people in the current study.

Alcoholic liver cirrhosis is a severe form of alcohol-related liver damage. More than 95% of heavy drinkers develop a fatty liver, but only 35% of them develop cirrhosis. We postulate that genetic factors may play a role in this difference. Genetic polymorphisms of the cytokine genes may influence Kupffer cells cytokine genes expression. In this study, we evaluated the promoter polymorphisms of interleukin (IL) 1β, IL 6, IL 10, and tumor necrosis factor alpha (TNFα) and aimed to clarify the association between the polymorphisms and the disease. Forty alcoholic patients with liver cirrhosis and 64 healthy volunteers were included in our investigation. Genotyping on IL 1β –511 T>C, IL 6 –572 G>C, IL 10 –819 C>T, IL 10 –1082 G>A, and TNFα –308 G>A was done. Another 36 patients with recurrent alcoholic pancreatitis were included as an additional control group. Genotyping on IL 10 –819 C>T and IL 10 –1082 G>A was done. The polymorphisms on IL 1 and IL 6 showed no significant association. The p value for TNFα –308 G>A was 0.028 in comparison with healthy volunteers. Although the p value was less than 0.05, it did not reach significance after Bonferroni correction. The p values for IL 10 –819 C>T and IL 10 –1082 G>A were respectively 0.031 and 0.026 in healthy volunteers and 0.028 and 0.023 in the alcoholic pancreatitis group. The results also did not reach significance after Bonferroni correction. Among the participants with the GCC haplotype, healthy volunteers had p = 0.027 (p
