[Neuropathology of the acquired immunodeficiency syndrome].
Neuropathology of acquired immunodeficiency syndrome. The Central Nervous System (CNS) has been examined at autopsy in 60 patients who died of AIDS in a 6-year period in our hospital. Most of the patients were intravenous drug abusers, the mean age was of 34 years, with a high prevalence of males. Neurologic symptoms were present in 62% of patients, while histologic lesions have been observed in 51 cases (85%). Opportunistic infections were found in 27 patients, the commonest being T. gondii (12) and Cytomegalovirus (7); Progressive Multifocal Leukoencephalopathy was observed in 2 cases. HIV-associated lesions included 21 cases of Multifocal Giant Cell Encephalitis (MGCE), 15 of Progressive Diffuse Leukoencephalopathy (PDL) and 7 cases of Vacuolar Myelopathy. Primary CNS lymphoma was noted in 8 patients and secondary deposits were observed in 3 cases. Simultaneous CNS lesions by more than one pathogen were frequently encountered. The main pathogenetic mechanisms for characterization of all the lesions and their relationship with clinical features of the disease are discussed. It is supposed that MGCE and PDL represent two different patterns of HIV-encephalopathy.
