Exogenous insulin and a second-generation sulphonylurea were independent variables associated with an incidence of HCC in hepatitis C patients with diabetes mellitus. This association was evident in patients who were non-cirrhotic. To verify a causal relationship between these antidiabetic agents and the development of HCC, a prospective cohort study is required.

BackgroundThe aim of this study was to evaluate the efficacy of daclatasvir plus asunaprevir therapy in patients infected with hepatitis C virus and determine its relevance to resistant variants.MethodsA total of 629 consecutive patients infected with hepatitis C virus genotype 1 were assessed. Daclatasvir (60 mg/day) plus asunaprevir (200 mg/day) was given for 24 weeks. The virological responses and resistance-associated substitutions of hepatitis C virus mutants were examined by the direct sequence and cycleave methods were evaluated.ResultsOverall, 89.4% (555/621) of patients exhibited a sustained virological response (SVR). The SVR rates in the patients with wild type, mixed, and mutant type Y93 by direct sequencing were 92.5% (520/562), 70.3% (26/37), and 42.9% (9/21), respectively. The SVR rates in the patients with 100%, 90%, 80%-30%, and 20%-0% Y93 wild by the cycleave method were 93.4% (456/488), 88.2%(30/34), 56.0%(14/25), and 36.8%(7/19), respectively. In contrast, the SVR rates for the wild type and mixed/mutant type L31 by direct sequencing were 90.2% (534/592) and 72.4% (21/29), respectively. In the multivariate analyses, the wild type Y93, no history of simeprevir therapy, the wild type L31, and low HCV RNA level were independent factors of SVR.ConclusionNS5A resistance-associated substitutions, especially Y93H, were major factors predicting the SVR. Although direct sequencing can predict the SVR rate, the cycleave method is considered to be more useful for predicting the SVR when used in combination.

Aims:The real-world efficacy of sofosbuvir/velpatasvir treatment for patients with hepatitis C virus-related decompensated cirrhosis is unclear. We aimed to identify factors that improve liver functional reserve after treatment. Methods:This was a multicenter retrospective study of 12-week sofosbuvir/velpatasvir treatment. A total of 48 patients with Child-Pugh (CP) class B or C were enrolled at 11 institutions. We evaluated changes in liver functional reserve at 24 weeks post-treatment.Results: At baseline, 40 and eight patients were CP class B and C, respectively. The overall rate of sustained virologic response 12 weeks post-treatment was 95.8% (46/48). Serum albumin, alanine aminotransferase and α-fetoprotein levels, and the FIB-4 index were significantly improved post-treatment (P < 0.05). Among patients who achieved sustained virologic response 12 weeks post-treatment, those with CP class A increased from 0 to 24 patients (56%) at 24 weeks post-treatment. In multivariate analysis, body mass index (BMI) ≥25 was an independent factor that inhibited CP class improvement (P < 0.05). In decision tree analysis, after treatment, the initial divergent variable for CP class improvement was hepatic encephalopathy, followed by serum sodium level and BMI. Conclusion:Sofosbuvir/velpatasvir treatment improved the liver functional reserve in patients with hepatitis C virus-related decompensated cirrhosis at 24 weeks posttreatment. However, BMI ≥25 inhibited improvement in CP class. Additionally, decision tree analysis revealed that a combination of hepatic encephalopathy, serum
