Abstrakt: Background and objectives: The clinical features and efficacies of antivirals for children with hepatitis C virus (HCV) infections that are acquired through different transmission routines are poorly understood worldwide. This study investigated the clinical characteristics of children who were infected via iatrogenic means and analyzed the efficacy of antiviral therapy in children with chronic hepatitis C (CHC). Methods: In total, 256 children with HCV infections aged 1 to 5 years were enrolled and surveyed. Interferon-α plus ribavirin was administered to 162 children with CHC for 24 or 48 weeks. The sustained virologic response (SVR) at 24 weeks post-treatment was determined. Results: The median duration of infection was 11.5 (range 6-24) months. The median age was 2.7 years, and 64.5 % of the subjects were male. Ninety-three children (36.3 %, 93/256) exhibited spontaneous resolution of the HCV infection. The remaining 163 (63.7 %) were HCV RNA-positive and had HCV genotypes 1b and 2a, which were identified in 42 and 58 %, respectively, of the 133 tested children. Liver biopsies were performed in all HCV RNA-detectable children. A total of 23.9 % cases exhibited grade 2 activity, and 30.1 % exhibited stage 2/3 liver fibrosis. The serum HCV RNA levels were positively correlated with the aminotransferases. Of the 162 treated CHC children, 158 (97.5 %) achieved SVR. The side effects were mild, and 158 (97.5 %) of the treated patients tolerated the treatment well. Conclusions: This study revealed that histological liver disease can be present within 6-24 months of acquiring an HCV infection in children aged 1-5 years. Interferon-α plus ribavirin therapy is a highly effective and cost-effective means of managing children with early-stage chronic HCV infection. [ABSTRACT FROM AUTHOR]
