Mitochondrial toxicity is associated with virological response in patients with HIV and hepatitis C virus coinfection treated with ribavirin and highly active antiretroviral therapy.

摘要

The combination of highly active antiretroviral therapy (HAART) plus ribavirin (RBV) in patients with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) coinfection has been reported to cause mitochondrial toxicity (MT). Sixty-four patients with HIV-HCV coinfection who were receiving antiviral therapy were evaluated for MT. Patients with concomitant HAART showed greater increases in lactate levels than did patients without HAART, and this difference was more pronounced in patients who received higher dosages of RBV. The incidence of pancreatic enzyme elevations and symptomatic pancreatitis was higher among patients who received HAART and high-dose RBV. Hepatic steatosis increased in patients who received HAART and high-dose RBV. Patients who showed signs of MT achieved higher rates of sustained virologic response than did patients without MT (73% vs 44%).
