Infections of human immunodeficiency virus (HIV), hepatitis B (HBV) and C (HCV) viruses are among the grave health concerns confronting global public health. These infections spread via similar routes (e.g. parenteral, sexual and vertical), leading to the anticipation of high prevalence rates of HBV and HCV co-infections among HIV infected patients. HBV and HCV co-infections in HIV-positive patients lead to severe liver disease by means of rapid progression to hepatocellular carcinoma and severe chronic hepatitis. Consequently, the co-infection of these viruses is strongly associated with reduced survival of HIV patients. Various studies have been conducted among Iranian HIV-positive patients to identify HBV/HIV, HCV/HIV and HBV/HCV/HIV co-infection prevalence rates and their correlations. These surveys have been conducted in many cities and a variety of settings throughout the country. These studies have shown that the alarming high rates of HBV/HCV co-infection among HIV patients highlight the need for a timely and systematic assessment of these patients. It is evident that early diagnosis and early start of appropriate treatments could increase the length of life for co-infected HIV patients; therefore, comprehensive identification of risk factors and underlying conditions, as well as HIV treatment, are highly recommended to prevent HBV/HCV co-infection among HIV-positive patients.
