Abstract

Graphic abstract

Clinical data on children with chronic hepatitis C (CHC) remain extremely limited. This study investigated sustained virologic response (SVR) to alfa-interferon 2b plus RBV treatment in children aged 1-6 years with unsafe injection-acquired CHC. 154 children with CHC aged 1 to 6 years were enrolled, 101 of them were male (65.6%) and 53 were female (34.4%), and they were treated with alfa-interferon at a dose of 1-5 MIU/m2 3 times weekly plus oral RBV (15 mg/kg/day) for 48 weeks. 57(39.3 %) of them were genotype 1b, 73(50.3%) were genotypes 2a, 15(10.3%) were undecided type. SVR was achieved in 53 of 57(93.0%) patients with genotype 1b, in 72 (98.6%) of 73 with genotype 2a, 15(100.0%) of 15 with undecided type. There was no significant statistical difference in SVR between male and female (98.0% vs 94.3%, p=0.340), genotype 2a and those with genotype 1b(98.6% vs 93.0%, p=0.160), ALT>40U/L group and ALT≤40U/L group(96.7% vs 96.8%, p=1.000), AST>40U/L group and AST≤40U/L group(95.9% vs 98.2%, p=0.654) as well as lower baseline viral load group (<6×105 IU/ml) and higher baseline viral load group(≥6×105 IU/ml)(97.3% vs 95.3%, p=0.916). Leucopenia, neutropenia, hemoglobin concentration decrease, fever, platelet count decrease and rash were 8.4%, 69.5%, 24.0%, 50.6%, 1.9% and 4.5%, respectively. And only 12(7.8%) individuals developed thyroid autoantibodies. The SVR was higher in patients with IL-28B genotype C/C than C/T (99.0% vs 80%, p=0.002). Compared with HCV viral genotype, ALT level and baseline viral load, IL-28B rs12979860 is more suitable for predicting antiviral efficacy in children with CHC. It is inappropriate to take the increase of ALT level as an essential indicator for antiviral treatment in children aged 1-6 years.
