RESUMEN

Knowledge of the predictors of sustained viral response [SVR] to pegylated interferon [PEG-INF] alfa-2a and ribavirin [RBV] therapy in patients with hepatitis C genotype-4 [HCV-4] is crucial for selecting patients who would benefit most from therapy. We assessed the predictors of SVR to this combination therapy in Saudi patients with chronic HCV-4 infection. This retrospective study included 148 patients with HCV-4 infection who underwwent clinical, biochemical and virological assessments before treatment and at 12, 24, 48 and 72 weeks posttreatment. Of the 148 patients, 90 [60.8%] were males. Mean [SD] for age was 48.5 [12.7] years and BMI was 27.9 [7.5] kg/m[2]. Seventy-nine of 148 [60.1%] patients were treatment naive and 110 [74.3%] underwent pre-treatment liver biopsy. Eighteen [12.2%] patients did not complete therapy because of side effects or they were lost to follow up. Early virological response was achieved in 84 of 91 [92.3%] patients. In the 130 [87.8%] patients who completed therapy, 34 [26.2%] were non-responders and 96 [63.8%] achieved end-of-treatment virological response [ETVR]. SVR and virological relapse [24 weeks after ETVR] occurred in 66/130 [50.7%] and 30/130 [31.2%] patients, resspectively. Compared to relapsers, sustained responders were significantly younger [P = .005], non-diabetic [P = .005], had higher serum albumin [P = .028], lower alpha-fetoprotein level [P = .026], lower aspartate aminotransferase [AST] [P = .04] levels, and were treatment-naive [P = .008]. In a multivariate regression analysis, the independent predictors of SVR were younger age [P = .016], lower serum AST [P = .012], and being treatment na‹ve [P = .021]. Approximately half of HCV-4 patients who complete the course of combination therapy achieve an SVR, especially if they are young, treatment naive and have lower AST levels
