ObjectivesHuman immunodeficiency virus (HIV) infection in Sub-Saharan Africa is complicated by co-infection with hepatitis B and C viruses (HBV and HCV), which share similar transmission routes. The aims of this study were to determine the prevalence of hepatitis B surface antigen (HBsAg)-positive and HBsAg-negative HBV infection and of HCV infection among HIV-infected patients.MethodsA cross-sectional study was conducted among treatment-naïve HIV-positive adults in Khartoum State. HBV, HCV, and HIV infections were detected using immunoassays for HBsAg, hepatitis B core antibodies (anti-HBc), hepatitis C antibodies (anti-HCV), and HIV antibodies (anti-HIV), while real-time PCR was used to measure HBV DNA.ResultsThe mean age of the 358 patients was 35.2±9.3 years and the male to female ratio was 1.3:1.0. The mean alanine aminotransferase (ALT) level was 10.9±18.0 U/l. Evidence of 23, current or past HBV infection was detected in 62.8% of the patients. HBV DNA was detected in 96 patients (26.8%), 42 HBsAg-positive (11.7%) and 54 (15.1%) HBsAg-negative, indicating occult hepatitis B infection. Anti-HCV was detected in 1.7%.ConclusionsEvidence of HBV infection was detected in 26.8% of HIV patients with HBsAg-negative infection, with viraemia detected in 15.1% of the patients. All HIV-infected patients should be screened carefully for HBV infection with HBsAg and anti-HBc IgG antibodies prior to starting antiretroviral therapy.Copyright © 2014 The Authors.
