Hepatitis E virus infection in pregnancy in Ethiopia.
Thirty-two pregnant and 34 nonpregnant Ethiopian women between 15 and 45 years of age with sporadic acute viral hepatitis were studied consecutively. Demographic data including family size, monthly income and nutritional status as well as hepatitis virus markers were compared in the pregnant and nonpregnant groups. Only 3 nonpregnant women had hepatitis A infection. Hepatitis B infection was diagnosed in 4 pregnant and 9 nonpregnant women. Nineteen (59%) pregnant women had hepatitis E virus (HEV) infection as compared to 7 (22%) in the nonpregnant group (Relative risk = 2.88; 95% Confidence interval = 1.4-5.9). The remaining 9 pregnant and 15 nonpregnant women had non-A, non-B, non-E (NANBNE) hepatitis. Of a total of 10 maternal deaths, 9 occurred (7 during the third trimester) in the pregnant group, 8 in association with HEV infection. Two deaths, one from each group, were due to NANBNE hepatitis. In addition to 6 foetal losses as a result of maternal death, there were 2 foetal deaths and 7 premature deliveries as a direct result of acute viral hepatitis, all but 2 associated with HEV infection. Comparison of socioeconomic and nutritional status, clinical features, mean aminotransferase and bilirubin levels did not show differences in the two groups. Thus, pregnant women are more at risk to acquire HEV infection than nonpregnant women and HEV infection in this group of Ethiopian pregnant women is associated with high maternal mortality and neonatal complications.(ABSTRACT TRUNCATED AT 250 WORDS)
