Progressive multifocal leucoencephlopathy in AIDS patients: Hepatotoxicity of HAART in patients with hepatitis B or C. An. Med. Interna (Madrid) [online]. 2005, vol.22, n.8, pp.376-378.

Progressive multifocal leukoencephalopathy (PML) develops in 1-8% of patients with AIDS, for which it is a disease-defining condition. PML presents mainly in severely immunocompromised male intravenous drug users, having viral loads greater than log5 RNA copies/mL and CD4 populations lower than 150 cells/mm3. Death of AIDS patients with PML occurred after only 4 to 6 months before the introduction of highly active antiretroviral therapies (HAART), the only ones that have shown to prolong survival. Viral hepatitis is not the only liver condition affecting patients with AIDS, opportunistic infections and neoplasms, such as lymphoma and Kaposi´s sarcoma, as well as biliary disease are also encountered but, fortunately, they are currently less frequent as a result of the new antiretroviral treatments. The risks of HAART hepatotoxicity in patients with hepatitis B or C have been studied by several groups.
