Seroepidemiology of hepatitis B virus among human immunodeficiency virus-infected patients in a tertiary hospital in Nigeria

Aim: This study was aimed at determining the prevalence and associated risk factors for hepatitis B virus (HBV) infection among human immunodeficiency virus (HIV)-infected patients in a tertiary teaching hospital in Nigeria. Patients and Methods: Venous blood was collected from a total of 1680 (comprising of 1177 HIV infected and 503 non-HIV infected) patients and tested for the presence of HbsAg using immunochromatographic technique. Results: The seroprevalence of HBV among HIV and non-HIV-infected patients was 3.8% and 3.6%, respectively. HIV was not identified as a risk factor for HBV seropositivity (P = 0.919). A statistically significant association was found to exist between CD4 count
