The prevalence of serological mercers of HCV-infection among HIV-infected persons is investigated. The frequency of HCV activation and the genotyping structure of HCV population in HIV/HCV-coinfected patients are determined. The HCV viral loads are measured, the relationship between HCV viral load and HIV viral load, between HCV viral load and CD4 T-cell count is studied. A significant direct relationship between HCV viral load and HIV viral load and a significant inverse relationship between HCV viralload and CD4 T-cell count were found in patients who not receive HAART.
