ABSTRACT
<p><b>OBJECTIVE</b>To investigate the clinical features, CD4+ T and CD8+ T cell counts, HIV RNA load, HCV RNA load, CD8+ T cell responses to HCV of HIV/HCV co-infected and HCV mono-infected patients and to assess the mutual influences of the two viruses in the infection.</p><p><b>METHODS</b>Fifty-nine patients with HIV/HCV co-infection were enrolled in this study. Thirty-six patients with HCV mono-infection served as a comparison group. The liver function, peripheral blood CD4+ T and CD8+ T cell counts, HIV RNA load and HCV RNA load were compared between the groups. Peripheral blood mononuclear cells were analyzed by interferon-gamma ELISpot using a panel of HCV antigens.</p><p><b>RESULTS</b>The frequency of HIV/HCV co-infection in those blood donors in Henan, China was 60.8%. ALT and AST in the HIV/HCV co-infection patients were not different from those of the HCV group. Globulin in the HIV/HCV co-infection group was higher than that in the HCV group (P<0.01). CD4+ T cell counts in the HIV/HCV co-infection group were lower than those in the HCV group, but CD8+ T cell counts in the HIV/HCV co-infection group were higher than those in the HCV group (P<0.01). The HCV RNA loads were higher in the HIV/HCV co-infection group than in the HCV group(P<0.01). The magnitude of HCV-specific CTL response to HCV-NS3 overlapping peptides in the HIV/HCV co-infection group (649.34+/-685.90) was higher than that in the HCV group (1233.70+/-1085.16). Albumin was negatively correlated with HCV RNA (log10copies/ml) in the HIV/HCV co-infection group (r=-0.540). A positive correlation was found between platelet and peripheral blood CD4+ T cell counts (P<0.05). No linear correlation was found between HCV virus loads, HIV virus loads or peripheral blood CD4+ T cell counts.</p><p><b>CONCLUSION</b>The frequency of HIV/HCV co-infection in the blood donors in Henan, China was 60.8%. HIV/HCV co-infection aggravated the progress of chronic hepatitis C.</p>
