Management of chronic hepatitis C infection in children

摘要

Purpose of review: Chronic hepatitis C infection remains a global public health burden and has important clinical implications due to progressive liver fibrosis and development of cirrhosis and its complications. The role of antiviral therapy in infected children is an area of controversy due to an indolent clinical course in the majority of children, and a low likelihood of viral eradication in response to an intensive interferon-based treatment course that is associated with a wide spectrum of adverse effects. This review summarizes new concepts in the epidemiology, natural history, and management of chronic hepatitis C infection in children. Recent findings: In the past 18 months, two large prospective studies demonstrated high rates of sustained virologic response in children with chronic hepatitis C infection, estimated at 53% in genotype 1 with peginterferon α-2b-ribavirin, and 47% in genotype 1 with peginterferon α-2a-ribavirin. On this basis, both combination regimens have been recently approved by the Food and Drug Administration (FDA) for use in children. Summary: Children with hepatitis C infection may benefit from early treatment, and the decision to pursue antiviral therapy should be based on individual assessment of host and viral characteristics, and stage of liver fibrosis.
