title: Hepatitis C in HIV-infected patients--therapeutic approach.
abstract: The use of highly active antiretroviral therapy (HAART) has extended the lifespan of patients infected with human immunodeficiency virus (HIV). As the prognosis of HIV infection has improved, liver disease associated with hepatitis C virus (HCV) has become clinically significant in patients with HIV, liver failure being a frequent cause of death in this population. HIV infection may accelerate the course of liver disease in patients co-infected with HCV, so infection with HCV should be treated like any other opportunistic disease in these patients. Nowadays, combination therapy with interferon-alpha and ribavirin is the standard treatment for chronic hepatitis C in HIV-negative patients. Preliminary results of combination therapy in HIV/HCV co-infected patients have been promising, showing a sustained response rate in 40% of these patients. Patients with higher CD4 counts and lower HCV/HIV viral load and those infected with HCV genotype 3a have a better response to therapy. Potential drug interactions between HAART therapy and interferon and ribavirin treatment emphasize the importance of initiating treatment of HCV infection in HIV-positive individuals as soon as possible and ideally before the need for anti-HIV therapy. Recent case reports have suggested that liver transplantation might be an appropriate procedure in HIV patients with undetectable HIV viral load, high CD4 counts and HCV advanced liver disease. However, the limited amount of available information and the complexities of drug interactions between HAART therapy and immunosuppressive drugs oblige us to be prudent within considering such a procedure.
