Peginterferon alfa-2a plus ribavirin for chronic hepatitis C virus infection in children and adolescents

BACKGROUND & AIMS: This multi-center study aimed to prospectively evaluate the safety and efficacy of a genotype-based Pegylated Interferon alfa-2a/Ribavirin therapy in treatment-naïve hepatitis C virus (HCV), positive HCV serology and quantifiable HCV RNA, infected children. METHODS: Eighteen children with genotypes 2 and 3 patients (group A) were assigned to medication for 24weeks, and 47 children with genotypes 1, 4, 5 and 6 patients (group B) for 48weeks. RESULTS: Early response at week 12 was observed in 83% of group A patients and in 57% of group B patients (p<0.05). End of treatment response was achieved in 94% of patients in group A and in 57% in group B (p<0.001). Sustained virologic response was maintained in 89% of patients in group A and in 57% of patients in group B (p
