Hepatitis B virus infection amongst pregnant women in North-Eastern Nigeria- A call for action

Abstract

BACKGROUND: It is well known that Hepatitis B virus infection is endemic in Nigeria. Even though studies have been carried out on Hepatitis B virus infection in different parts of Nigeria, and in different sub-groups of individuals, information regarding the prevalence of Hepatitis B virus infection in pregnant women is scanty especially from the North-eastern region of Nigeria. We therefore determined the seroprevalence of Hepatitis B surface antigen (HBsAg) amongst pregnant women in North Eastern Nigeria. MATERIALS AND METHODS: A hospital-based cross-sectional study was carried out. The setting was the ante-natal clinic of the Federal Medical Centre, Yola, Nigeria. The duration of the study was from July 2008 to December 2008. Two hundred and thirty-one consecutively recruited pregnant women were screened for Hepatitis B surface antigen. Positive samples were re-tested using ELISA to eliminate false positives. Their biodata were obtained using a questionnaire to establish the presence of possible risk factors such as blood transfusion, surgery, etc. Written informed consent was obtained from each woman. RESULTS: Out of the 231 pregnant women tested, nineteen of them were seropositive for Hepatitis B virus infection giving an infection rate of 8.2%. Women in the age group 25-29 years had the highest HBV infection rate. CONCLUSION: This study confirms a high seroprevalence of Hepatitis B virus infect ion amongst pregnant women. It is recommended that pregnant women should be routinely screened for Hepatitis B virus infection as part of antenatal care services.
