Profile of hepatitis A infection with atypical manifestations in children.

ABSTRACT

We assessed the clinical course and biochemical profile of symptomatic children with viral hepatitis A who had atypical manifestations. Of 229 children with hepatitis A, atypical manifestations were found in 32 (14%) subjects. Prolonged cholestasis (n = 14), acute liver failure (9), relapse (9), ascites (8), and hematological problems (8) were the common presentations. Liver histology was suggestive of chronic liver disease in six children with protracted jaundice. Patients with atypical presentations were older (7.7 [1.6] years vs. 6.5 [2.6] years; p=0.012) and had higher total serum bilirubin (13.7 [8.1] mg/dL vs. 7.2 [4.0] mg/dL; p=<0.001) than those with typical presentation. Approximately 15% of children with acute hepatitis A infection have atypical presentation which is associated with increase in morbidity.
