Management of hepatitis C in HIV-infected persons.

摘要

The life expectancy of HIV-infected persons has extended significantly since the introduction of highly active antiretroviral therapies. Although classical opportunistic infections are now rarely seen, the toxicity of antiretroviral drugs as well as liver disease caused by hepatitis viruses represent an increasing cause of morbidity and mortality among HIV-positive persons. Since the rate of hepatitis C virus (HCV) infection is high among HIV carriers (up to 75% among intravenous drug users), HCV/HIV coinfection is widely prevalent. Predisposing liver damage favors a higher rate of hepatotoxicity of antiretroviral drugs, which can limit the benefit of HIV treatment in some individuals. Overall, severe hepatotoxicity appears in around 10% of subjects who began triple combinations including either protease inhibitors or non-nucleosides. The progression to cirrhosis seems to occur faster in the setting of HIV infection, and conversely recent data demonstrate that HCV infection can accelerate the progression to AIDS in HIV-positive persons. Although clinicians have been reluctant to treat hepatitis C in HIV-infected people, this therapeutic nihilism is unwarranted. The availability of new more successful regimens to treat hepatitis C, in particular using the new pegylated forms of interferon in combination with ribavirin, open new hopes for the care of HIV-HCV-coinfected persons.
