Impact of human immunodeficiency virus infection in patients infected with the hepatitis C virus

Background/Aims: The objective of the present study is to evaluate the impact of human immunodeficiency virus (HIV) in patients with hepatitis C virus (HCV) infection. Methods: Three different groups of patients were considered: group 1, 385 HCV/HIV coinfected; group 2, 198 HIV monoinfected; and group 3, 311 HCV monoinfected. Demographic and epidemiological data were collected. Blood tests included anti-HCV, HCV-RNA test, genotyping, CD4 cell count, anti-HIV, and HIV viral load. Treatment with interferon and ribavirin was proposed. The fibrosis progression rate was assessed. Results: The most prevalent risk factor in the group of coinfected was the use of intravenous drugs; in the HIV monoinfection group, heterosexual relations at risk; in the HCV monoinfection group, the transfusion of blood. There was no difference concerning the distribution of genotypes or HCV viral load between groups 1 and 3. Although the mean time of duration of HCV infection was greater in group 3 than in group 1, there was no difference when the fibrosis progression rate was evaluated. The response to treatment was similar. Conclusion: In the present series there was no relevant impact of HCV infection in patients with HIV.
