Prevalence of sorologic markers of HBV and HCV infection in HIV-1 seropositivr patients in Florionópolis, Brazil

ABSTRACT

B and C hepatitis are infections transmitted in ways similar to the human immunodeficiency virus (HIV). The present study was designed to assess the prevalence of hepatitis B (HBV) and hepatitis C (HCV) virus infection in HIV-1-infected patients who lived in the metropolitan areas of Florianópolis, in the State of Santa Catarina. Ninety-three patients seropositive to HIV-1 were identified by using enzyme-linked immunosorbent assay (ELISA) and indirect immunofluorescence. Patients were assigned to according to HIV-1 transmission risk homosexuals (n=20), heterosexuals (n=39), and intravenous drugs users (IVDU) (N=34). HbsAg, Anti-HBc, Anti-HBc IgM and Anti-HCV measurements were done using ELISA. HBV and HCV prevalence in HIV-1 infected patients was 71 percen and 53.8 percent, respectively. In the IVDU group, the prevalence of HBV (85.3 percent), of HCV (88.2 percent), and infections by both viruses (76.5 percent) was greater than that observed in the heterosexual and homosexual groups. Hepatitis B markers (HbsAg and Anti-HBc) for chronic persistent disease were recorded in 24.3 percent of patients, and for past infection in 71.2 of patients. The evidence of high prevalence of HBV and HCV infections in HIV-1 seropositive patients, mainly among intravenous drug users, should be included in educational programs in an effort to decrease the incidence of multiple infections.
