To determine if hepatitis C virus seropositivity and active hepatitis B virus infection in HIV-positive patients vary with patients' geographic origins, we studied co-infections in HIV-seropositive adults. Active hepatitis B infection was more prevalent in persons from Africa, and hepatitis C seropositivity was more common in persons from eastern Europe.
Since the introduction of highly active antiretroviral treatment (HAART), non-AIDS defining conditions have become major causes of illness and death in HIV-infected patients. In particular, liver disease has emerged as a major cause of death in the HAART era (1,2). In HIV-infected patients, chronic liver conditions are mostly caused by hepatitis C virus (HCV) and hepatitis B virus (HBV) (3,4).
Worldwide distribution of both viruses is heterogeneous because of different patterns of transmission (5,6). In addition, HBV immunization programs at birth were implemented in some countries during the 1990s, which has led to a decrease in the proportion of chronic HBV carriers (6). As a consequence of these different patterns of risk and immunization, HCV and HBV prevalence vary across countries and even across regions in the same country (7,8). Several studies have addressed HBV and HCV prevalence in migrants and ethnic minorities (9,10), but few studied viral hepatitis co-infections in HIV-infected persons according to the patients' geographic origins (11,12).
In Spain, as in other high-income countries, migrants from developing countries represent a growing proportion of persons with HIV-infections (13). The question we addressed in our study was whether HCV seropositivity and active HBV infection in HIV-positive patients vary with the patients' geographic origins.
