Viral kinetic of HCV genotype-4 during pegylated interferon alpha 2a: ribavirin therapy.

Kinetics of hepatitis C virus (HCV) during pegylated interferon (PEG-IFN) and early monitoring of viral decline were recently described to predict treatment outcomes and in turn reduce the course of treatment, adverse effects and cost. However, there is limited (if any) information on the viral dynamics of HCV-4. Our aim is to follow the HCV-RNA kinetics during PEG-IFN alpha 2a and ribavirin therapy and the best time for predicting sustained viral response (SVR) in genotype-4 patients.
