Abstract


Objective: There are 350 million hepatitis B carriers world-wide. Mono-infection with Hepatitis B in urban South Africa has been estimated at approximately 1%. The exact prevalence rate of hepatitis B in the HIV population has not been well established. Hepatitis B screening is not standard of care in the HIV government clinics.
Coinfection with hepatitis B and HIV can influence ARV treatment and prognosis of both of these diseases. Evaluating the Hepatitis B/HIV coinfection prevalence was the goal of this study.

Design: This is the first prospective observational report of the prevalence of hepatitis B/HIV co infection in South Africa. Patients were recruited from a HIV clinic in regional hospital in Johannesburg. Previous hepatitis B serology could not have been previously done. Standard hepatitis B serology was performed.

Results: 502 participants were screened. The cohort’s average age was 37 +/- 9 years and an average CD4 count of 128 cells/mm3 Twenty- four (4.8%) were hepatitis B surface antigen positive. 47% of the participants showed some evidence of hepatitis B exposure. The risk of hepatitis B coinfecition was not significantly different by sex, race, CD4 count or age. Liver function tests were not a good predictor of hepatitis B infection.

Conclusion: The coinfection rate of hepatitis B/HIV as defined by hepatitis B surface antigen positivity is 5X the prevalence of non HIV infected individuals in urban SA. With a 5% hepatitis B/HIV coinfection rate, consideration to increase accessibility of Truvada for first line treatment for this population is imperative.
