Hepatitis B virus (HBV) is a leading cause of liver pathology, which has remained a serious public health challenge in spite of the availability of hepatitis B vaccine discovered about 40 years ago. People living with human immunodeficiency virus (PLHIV) are more at risk of hepatic problems as liver complications appear and progresses faster, owing to their immunocompromised status. This study seeks to determine HBV exposure, serological pattern, and HBV susceptibility among PLHIV. One hundred and fifty PLHIV were enrolled for the study. About 5 mL of blood was collected, processed, and tested for markers of hepatitis B virus: HBsAg, anti-HBs, HBeAg, anti-HBe, and anti-HBc. Twenty-eight (18.7%) had at least one serological marker while 122 (81.3%) tested negative to all the markers. The prevalence of HBsAg in this study was 8.7%, anti-HBs prevalence was 10%, while HBeAg was 2.7%, anti-HBe 6.0%, and anti-HBc 6.7%. Higher HBsAg, HBeAg, and anti-HBc prevalence were observed among the male participants with 13.9%, 5.6%, and 13.9%, respectively, while the female participants had more anti-HBs and anti-HBe of 1.8% and 6.1%, respectively. Age group 51-60 years had the highest prevalence of HBsAg (17.7%), HBeAg (11.8%), and anti-HBe (11.8%) while age group 31-40 years had the highest prevalence of anti-HBs (14.8%) and anti-HBe (9.8%). This study revealed the different serologic patterns of HBV infection among PLHIV and that susceptibility to HBV infection among PLHIV is high.
