Stable recovery from HCV in HIV-HCV co-infection under antiretroviral therapy.

Co-infection by the hepatitis C virus (HCV) and the human immunodeficiency virus (HIV) is common. HIV co-infection worsens the course of HCV infection, particularly in patients with low CD4-cell count, enhancing the need to cancel HCV replication in HIV-infected patients. We report a case of spontaneous recovery of chronic HCV-infection in a HCV-HIV co-infected hemophiliac with the introduction of combined antiretroviral therapy and immune restoration. Retrospective analysis of frozen blood samples showed that a decrease in HCV-RNA in parallel with the increase of CD4 and CD8-cell counts, accompanied by a peak of transaminases. The respective effect of immune restoration and of high doses of ritonavir are discussed.
