Abstract

Evidence has shown that the p7, NS2 and NS3 genes affect the outcome of pegylated-IFN-α/ribavirin (PEG-IFN/RBV) combination therapy in different populations with HCV infections. Here, we test the hypothesis that diversity in the p7, NS2 and NS3 genes influences the probability of obtaining either a sustained (SVR) or non-sustained (non-SVR) viral response in Chinese patients with genotype 1b chronic hepatitis C. There were significantly more unique variations in the p7, NS2 and NS3 genes in the sequences from SVR than non-SVR patients. Inter-patient variations related to treatment outcome in NS3 were concentrated in the protease domain. There were no significant differences in the frequency of variations in the core, E1 and E2 proteins between the groups. In conclusion, increased amino acid sequence diversity in the p7, NS2 and NS3 genes is associated with an SVR to PEG-IFN/RBV therapy in Chinese patients with genotype 1b chronic hepatitis C.
