The clinical features of hepatitis B virus infection and intrahepatic cholestasis in pregnancy

Objectives: This article aimed to explore the relationship between hepatitis B virus infection (HBV) and intrahepatic cholestasis in pregnancy (ICP). Material and methods: We conducted a retrospective study at the Beijing Youan Hospital in China between January 1, 2010 and November 31, 2016. In total, 217 pregnancies were identified and retrospectively studied. Characteristics, pregnant outcomes and the rate of mother-to-child transmission (MTCT) of HBV were compared between groups. Results: Elevate of total bile acid occurred mainly during the second and third trimester among HBV with ICP (HBV + ICP) patients. The rate of preterm birth occurred more frequently in HBV + ICP patients than both ICP and HBV patients (p < 0.05). Furthermore HBV + ICP patients had a higher percentage of cesarean section, postpartum hemorrhage Apgar < 7 at 1/5 min, AFIII and LBWI rate than HBV patients (p > 0.05) but did not have an increased incidence of fetal loss or birth defect when compared with that in HBV and ICP patients (p > 0.05). Conclusions: HBV + ICP patients have adverse pregnant outcomes and as a high occurrence in the second and third trimesters of pregnancy monitoring should be enhanced at this time.
