  Objective: Rapid virological response (RVR), defined as undetectable serum hepatitis C virus (HCV) RNA at week 4, is a useful predictor of sustained virological response (SVR) to peginterferon (PEG-IFN) plus ribavirin (RBV) therapy and protease inhibitor (telaprevir (TVR)/simeprevir (SMV)) based triple therapy for patients infected with genotype 1 HCV. The aim of this study was to predict SVR using viral response within 2 weeks of therapy initiation. Methods: Fifty-two HCV genotype 1b patients with high viral loads treated with protease inhibitor (TVR/SMV)- based triple therapy were analysed. Thirty-seven patients were treated with TVR-based triple therapy and 15 with SMV-based triple therapy. HCV RNA levels were measured at the following points: the day of therapy initiation, at days 1 and 3, and at weeks 1 and 2. Results:.. View More»
