Hepatitis B and C infections in HIV-1 patients on combination antiretroviral therapy (cART) in Ghana: implications for immunologic recovery, clinical response to treatment, and hepatotoxicity

BACKGROUND: Viral hepatitis could have an impact on the treatment response in HIV patients. In this study, we sought to determine the prevalence of hepatitis B and C infections and examine the effect on the treatment response in HIV-1 patients attending antiretroviral therapy (ART) centers in the Volta and Oti Regions of Ghana. METHOD: A longitudinal study design was employed. A cohort of 200 newly diagnosed HIV-1 positive adults who met the inclusion criteria (CD4 count ≤350 cells/μl) were enrolled at three ART Centers and initiated on the combination Antiretroviral Therapy (cART) from January 2014 to December 2015. Blood samples obtained from each participant were subsequently screened for the presence of hepatitis B surface antigen (HBsAg) and hepatitis C antibody. Out of the 200 study respondents recruited, 93 HIV mono-infected were randomly selected plus all 17 HIV co-infected were prospectively followed for twelve months. Using standard methods, three consecutive measurements of CD4 cells, haemoglobin, and liver enzymes [(aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP)] as well as weight measurements were performed at baseline, six months and twelve months, respectively, after treatment initiation. RESULT: The overall HIV-viral hepatitis sero-positivity was 8.5%. HBV and HCV co-infections were 7.0% and 1.5% respectively. Among HIV mono-infected CD4 cell count, haemoglobin, and weight significantly increased from baseline to the twelfth month while levels remained statistically comparable in the HIV co-infected patients. The levels of AST, ALT, and ALP were more pronounced (hepatotoxicity) in the HIV co-infected compared to the HIV mono-infected at various time points within the twelve month. CONCLUSION: The frequency of HIV-hepatitis co-infection was high. This correlates with poor immunological outcome, clinical response to treatment and pronounced hepatotoxicity. The findings, therefore, underscore the need for regular screening of HIV patients for early detection and appropriate management.
