Cluster of differentiation 4+ T-cell counts and human immunodeficiency virus-1 viral load in patients coinfected with hepatitis B virus and hepatitis C virus.

Background: Coinfections of human immunodeficiency virus (HIV) with hepatitis viruses may affect the progress of disease and response to therapy.

Objectives: To study the incidence of hepatitis B virus (HBV) and hepatitis C virus (HCV) coinfections in HIV-positive patients and their influence on HIV-1 viral load and cluster of differentiation 4+ (CD4+) T-cell counts.

Materials And Methods: This pilot study was done on 179 HIV-positive patients attending antiretroviral therapy (ART) centre. Their blood samples were tested for HIV-1 viral load, CD4+ T-cell counts, hepatitis B surface antigen, anti-HCV antibodies, HBV DNA and HCV RNA polymerase chain reaction.

Results: Among the 179 patients, 7.82% (14/179) were coinfected with HBV and 4.46% (8/179) with HCV. Median CD4+ T-cell count of HIV monoinfected patients was 200 cells/μl and viral load was 1.67 log copies/μl. Median CD4+ T-cell counts of 193 cells/μl for HBV ( = 0.230) and 197 cells/μl for HCV ( = 0.610) coinfected patients were similar to that of HIV monoinfected patients. Viral load was higher in both HBV and HCV infected patients but statistically significant only for HCV ( = 0.017). Increase in CD4+ T-cell counts and decrease in HIV-1 viral load in coinfected patients on 2 years of ART were lower than that in HIV monoinfected patients.

Conclusion: HBV/HCV coinfected HIV patients had similar CD4+ T-cell counts as in HIV monoinfected patients, higher HIV viral load both in chemo-naive patients and in those on ART as compared to HIV monoinfected patients. However, this study needs to be done on a large scale to assess the impact of coinfection on CD4 count and HIV viral load with proper follow-up of patients every 6 months till at least 2 years.
