Co-infections of hepatitis B and C with human immunodeficiency virus among adult patients attending human immunodeficiency virus outpatients clinic in Benin City, Nigeria.

Background: Hepatitis B and C viral co-infections with human immunodeficiency virus (HIV) are known to affect progression, management, and outcome of HIV infection. This study was aimed to access the prevalence of hepatitis B and C co-infections in HIV-infected adult patients in the University of Benin Teaching Hospital with a view of understanding the gravity of this problem in the local population. Methods: The descriptive cross-sectional study was carried out on 342 HIV-infected adult patients on highly active antiretroviral therapy attending HIV Outpatients Clinic of University of Benin Teaching Hospital, between April and September, 2011. Patients' sera were screened for hepatitis B surface antigen (HBsAg) and anti-hepatitis C virus (HCV) using immunochromatographic-based kits. Clinical stage of HIV and CD4+ cell counts were equally evaluated. Data were analyzed using SPSS version 17. Results: Of the 324 HIV-infected patients screened, 53 (15.5%) were positive for HBsAg, 24 (7.0%) positive for hepatitis C virus antibodies (HCV-Ab), while 2 (0.6%) were positive for both viruses. Seroprevalence of HBsAg was higher in male (17.8%) than in female (14.7%) (chi(2) = 0.49, P = 0.49), while the reverse is the case for HCV-Ab; 7.1% for female and 6.7% for male (chi(2) = 0.02, P = 0.88). Seroprevalences of HBsAg and HCV-Ab were also higher among patients in World Health Organization disease stages 3-4 and patients with CD4+ cell count = 200 cell/mu l compared to those in stages 1-2 and with CD4+ cell count >200 cell/mu l. Conclusion: Co-infection with hepatitis B virus and HCV among HIV/acquired immune deficiency syndrome (AIDS) patients is still a problem in our environment. Screening for these viruses among HIV/AIDS patients will allow for early detection and proper management.
