Brief Summary:
Sustained virological response (SVR) to antiviral therapy in patients with chronic hepatitis C genotype 1 according to subtype (1a vs.1b) has not been extensively investigated. This observational study was carried out on a large group of "naïve" HCV patients to evaluate difference, if any, between HCV genotype 1 subtype 1a and 1b on the response to treatment with peginterferon (Peg-IFN) plus ribavirin.
Detailed Description:
Despite the challenging perspective of the new antiviral drugs directly acting on hepatitis C viral replication such as protease and polymerase inhibitors, nowadays the standard treatment in genotype 1-chronic hepatitis C (CHC) is the combination of peghylated interferon (PEG-IFN) and ribavirin for 48 weeks. It has been extensively shown that patients infected with HCV genotype 1 have a lower rate of viral response than those infected with genotype 2 and 3. In large randomized multinational trials, sustained virological response (SVR) of around 50% has been obtained with peginterferon α2a plus ribavirin in the more difficult to treat subgroup of patients infected with HCV genotype 1. Furthermore, advanced fibrosis is a predictive factor of non response to antiviral treatment in genotype 1 virus \[5-7\]. Very few studies have evaluated SVR difference, if any, between subtypes 1a and 1b.
We have carried out an observational study on a large cohort of HCV "naïve" patients to evaluate the influence of HCV subtypes 1 on the response to treatment with Peg-INF plus ribavirin.
