Little is known about the natural history of liver disease in human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected subjects under highly active antiretroviral therapy (HAART). The objectives of this study were to obtain information about the mortality, the incidence of hepatic decompensations, and the predictors thereof in this population. In a multicenter cohort study, the time to the first hepatic decompensation and the survival of 1,011 antiretroviral naïve, HIV/HCV-coinfected patients who started HAART and who were followed prospectively were analyzed.
