Background.  To date, no study has evaluated pegylated interferon for the treatment of chronic infection with hepatitis C virus (HCV) genotype 6. We aimed to determine the efficacy of pegylated interferon plus ribavirin for treating infection with genotype 6 versus genotype 1.

Methods.  Forty-two patients chronically infected with HCV (for genotype 1, n=21 ; for genotype 6, n=20  ) were treated with pegylated interferon a-2a (n=20) or a-2b (n=22) combined with oral ribavirin for 48 weeks.

Results.  There was no difference between genotypes 1 and 6 in the rates of early virological response (76% vs. 81%; P>.05) and end-of-treatment response (71% vs. 81%; P>.05). Patients infected with genotype 6 had a higher rate of sustained virological response (SVR) than did patients infected with genotype 1 (86% vs. 52%; P=.019). The overall adverse-effects profile was similar in both genotype groups. There was no significant difference in the rate of SVR between patients receiving pegylated interferon a-2a and those receiving a-2b. Multivariate analysis showed that genotype was the only significant factor associated with SVR (P=-039).

Conclusions.  Treatment with pegylated interferon and ribavirin for 48 weeks resulted in a significantly higher rate of SVR in patients infected with genotype 6 than in those infected with genotype 1. Further studies are required to determine whether lower dosages and 24 weeks of therapy may be sufficient for the treatment of genotype 6 infection.
