Maternal Hepatitis B Virus Infection, Pregnancy, and Infant Health Outcomes in Botswana

Abstract

Background: Hepatitis B virus (HBV) infection during pregnancy is associated with an increased risk of premature birth, cesarean sections, low birth weight, and an increased number of hospitalizations in infants. There are no reported data on the impact of maternal HBV status on pregnancy and infant health outcomes in Botswana. Objectives: We aimed to evaluate the association of maternal HBsAg+/occult HBV infection at delivery with pregnancy and infant health outcomes in Botswana. Methods: HBsAg positivity was tested using a murex HBsAg ELISA kit while occult HBV (OBI) was tested using COBAS® AmpliPrep COBAS® Taqman®. Results: The total number of maternal HBsAg+ and OBI infections was 57 out of 752 and termed as maternal HBV. Binary logistic regression was used to explore the possible impact of maternal HBV status on each outcome, adjusted for maternal HIV status, ART use during pregnancy, and maternal age. Conclusions: In conclusion, there was no association between maternal HBsAg+/occult HBV infection and preterm birth (< 37 weeks), stillbirth, low birth weight (< 2.5 kg), and infant hospitalization (by 24 months).
