The maternal and fetal outcomes of 50 pregnancies complicated by acute viral hepatitis were examined. Twenty (40%) cases were due to type B hepatitis virus. The clinical course of the maternal hepatitis was unaffected by the pregnant state. Maternal hepatitis (type B or nontype B) had no effect on the incidence of congenital malformations, stillbirths, abortions, or intrauterine malnutrition; it did increase the incidence of prematurity (type B 31.6%; nontype B 25%; overall 27.6%) over that seen in the general delivery population (10 to 11%). Eight mothers acquired acute type B hepatitis during the third trimester; two of their infants (25%) were found to be chronic asymptomatic carriers of hepatitis B surface antigen and to have mild, persistent elevations of SGOT for up to 45 months.
