title: [Children and adolescents with hepatitis C virus infection].
abstract: Prevalence of infection with hepatitis C virus (HCV) is lower in children than in adults. The detection rate of anti-HCV antibodies in Western countries is 0.1-0.4% among children and adolescents. Prevalence of serologic response is higher in risk groups. HCV infection in children is usually asymptomatic, most of them have variations in serum levels of alanine aminotransferase (ALA). The laboratory exams for children are the same as those for adults. Histological progression may be faster in children than in adults. In this age group, HCV infection is considered as a special category, in which case it's possible to maintain the patient in observation without antiviral therapy. However, some studies with monotherapy showed that a regime with 1.75-3 MU/m2 of interferon alpha during 6-12 months induces a sustained viral response in 33-56% of the children. Although ribavirin hasn't yet been accepted for pediatric use, there have been several clinical tests in small groups with oral doses of 15 mg/kg a day, combined with interferon, during 12 months. The results are good. Pegylated interferon alpha is not authorized for pediatric use.
