BackgroundHepatitis C is the most frequently encountered hepatic disease in dialysis patients. Data related to pegylated interferon alfa-2a (Peg-IFN-α-2a) use in hemodialysis patients with hepatitis C virus (HCV) are limited. The aim of this study was to evaluate the efficacy of Peg-IFN-α-2a among these patients.MethodsForty-one IFN-naive hemodialysis patients infected by HCV were assessed. All patients had positive anti-HCV antibody and positive HCV-RNA. Peg-IFN-α-2a 135 mcg/week was given for 48 weeks. Biochemical and virological responses were evaluated at treatment weeks 12, 24, 48, and 72.ResultsThirty-eight of the 41 patients who completed the treatment enrolled in the study. Mean age of the 38 patients was 38.1 (range 23-65) years, and the study group was predominantly male (65.8 %). There was no statistically significant difference in mean age, gender, mean duration of hemodialysis, HCV infection, patient numbers with normal alanine aminotransferase (ALT) values and mean ALT, platelet, and HCV-RNA values between patients who achieved sustained virological response (SVR) and those who did not. Only the Knodell histology activity index correlated with SVR (P = 0.048). Biochemical and virological response rates at the 12th week (early response) were 94.7 % and 60.5 %, respectively. The 34 (89.5 %) patients achieved biochemical response at the end of therapy (48th week); 24 (63.2 %) remained HCV-RNA negative. At the 72nd week, biochemical and virological response rates were 84.2 % and 50 %, respectively.DiscussionAccording to results of this study, patients achieved good sustained viral and biochemical response rates with Peg-IFN-α-2a treatment. Histology activity index may be a predictor for SVR; but large randomized controlled trials are needed. Weekly 135 mcg dose of Peg-IFN-α-2a for 48 weeks is an effective treatment in HCV-infected hemodialysis patients.
