Retrospective analysis of acute hepatitis e infection in hospitalized pregnant cases

ABSTRACT

Hepatitis E virus [HEV] is endemic in Pakistan with 16-19% seropositivity of HEV IgG antibodies. The HEV is considered fatal during pregnancy as compared to general population. The objective of the study was to determine the maternal and fetal morbidity and mortality in HEV IgM positive pregnant cases. The study was conducted in four hospitals i.e. Pakistan Institute of Medical Sciences, Islamabad, Isra University Hospital Jamshoro, Sindh, Lady reading Hospital and Hayatabad Medical Complex, Peshawar, Khyber Pakhtoonkhwa. The medical record of pregnant cases from 2008 to 2011 was retrieved who were positive for HEV IgM. Information about age, gestational age, viral markers [HEV IgM, HBsAg, anti HCV], complications during pregnancy and outcome were recorded on pre design questionnaire. Data was analyzed using SPSS version 15. Medical record of 70 HEV positive pregnant cases was retrieved and out of these, 34 were found complete and analyzed further. The median age was 26 years. Twenty six pregnancies [76%] were in 3[rd] trimesters, 05 in 2[nd] trimester and 01 in 1[st] trimester. Pruiritis was the commonest symptom [28 cases], followed by jaundice [27], nausea/ vomiting [25] and encephalopathy [18]. Of 34 cases, 12 were artificially induced, 08 had premature labor, 04 delivered spontaneously [full term], 04 died undelivered and 04 continued till term. One got delivered at home and another had an abortion at home before coming to hospital. A total of 12 mothers along with their undelivered babies died, of these 08 were in 3[rd] trimester and 04 in 2[nd] trimester. Four out of 07 babies who were delivered prematurely also died. Maternal mortality was directly associated with delivery as 24 out of 34 mothers survived who were delivered either naturally or were induced while 12 out of 34 who continued their pregnancy died [p<=0 .004]. Third trimester had the highest maternal death. Acute hepatitis E during pregnancy led to 35% maternal and 47% fetal mortality. Acute hepatitis in pregnancy should always be screened for HEV and if found positive should be vigilantly followed to save mother and child
