Seroprevalence of anti-HCV and hepatitis B surface antigen in HIV infected patients.

Human immunodeficiency virus (HIV) is known to influence the natural history of infections with certain hepatitis viruses and interactions between HIV and hepatitis viruses may potentiate HIV replication. There is high degree of epidemiological similarity between hepatitis B virus and HIV as regard to high-risk group and route of transmission. Transmission of hepatitis C virus (HCV) through blood transfusion and intravenous drug abuse is well documented. Present study deals with the study of concurrent infection of HBV and HCV with HIV infection. In the study of 110 HIV seropositive patients, 34(30.4%) were positive for HBV and 8(7.27%) for HCV. The difference of concomitant infection was highly significant compared to controls. (p value < 0.0001). Heterosexual high risk behaviour was observed in 89(80.91%) of 110 HIV positive patients, out of which 23(25.8%) and 5(5.62%) were HBsAg and anti-HCV positive respectively. History of transmission was unclear in remaining patients. Concomitant infection of HIV and HBV was found to be significantly more in the symptomatic group (40.68%) compared to asymptomatic group (19.6%). As HIV infection is known to affect the natural history of both HBV and HCV infection, screening of their concurrent association is necessary.
