[Central nervous system infections in HIV patients in the era of high activity antiretroviral treatment].

Although the incidence of most central nervous system infections in HIV+ patients has decreased after the introduction of the modern antiretroviral treatments, they are still a major cause of morbidity and mortality. New technologies in molecular biology and neuroradiology establish the diagnosis in many cases and have decreased the need for cerebral biopsy. Prognosis has improved substantially after the introduction of high activity antiretroviral treatment; more active treatments are needed, however, for infections as PML or citomegalovirus encephalitis because of their still unacceptably high mortality.
