Acute hepatitis in childhood: virological, immunological and clinical aspects.

Virological, immunological and clinical findings in 7 previously healthy children, aged 18 months to 11 years, with viral hepatitis are reported. Asymptomatic and fully recovering, although protracted, hepatitis B was diagnosed by chance in a 1 1/2 year-old boy. Anicteric and short-term hepatitis occurred in three children with Epstein-Barr virus infection, concomitantly with typical mononucleosis syndrome. On the contrary, cytomegalovirus (CMV)-associated hepatitis was severe and protracted in two children, and fatal in a 4-year-old girl, whose main autoptic finding was submassive hepatic necrosis. Therefore, our study showed that acute viral hepatitis in non-immunocompromised children is generally self-limited and that CMV hepatitis is more frequent and severe than commonly believed.
