Purpose: To analyze the prevalence and the incidence of hepatitis C virus (HCV) seropositivity in sexually transmitted human immunodeficiency virus (HIV) patients.
Methods: Observational study of 1468 sexually transmitted HIV-infected patients from 7 hospitals (Southern Spain). Characteristics of HCV cases, and incidence of HCV seroconversion was assessed.
Results: Seroprevalence of HCV was 16.1%, higher among heterosexual than homosexual patients, and similar between heterosexual men and women. Seroincidence was 0.16 cases per 100 patient-years, similar between homosexual and heterosexual patients. HCV patients had a mean CD4 of 523 cells/microl, 82.0% were on highly active antiretroviral therapy (HAART), and 72.0% had undetectable HIV viral load. Serum HCV-RNA was positive in 79.0% cases, and only 16.0% had ever received HCV treatment.
Conclusions: HCV seroprevalence among sexually transmitted HIV-infected patients is more frequent than in the general population; however, incidence of HCV infection is currently low. Patients with sexually transmitted HIV coinfected with HCV have their HIV infection well controlled, but HCV infection was treated in few cases.
