Post-mortem study of every patient who died from AIDS in Pitié-Salpêtrire Hospital from June 1984 to November 1985 was performed without regard to the presence of neurological signs and symptoms. Autopsy were performed in 31/48 cases. Patients had been hospitalized in the Departments of Parasitology-Infectious Disease (24 cases) Internal Medicine (4 cases) and Neurology (3 cases). In every case, formalin-fixed material from the brain and the spinal cord were embedded in paraffin (20 samples), stained with hematoxylin-eosin, PAS, Alcian blue, Giemsa, Grocott and Ziehl techniques and Bodian's silver impregnation along with Luxol fast blue, and, in celloïdin (8 samples), stained with hematoxylin-eosin and Loyez' impregnation. There were 30 men (27 caucasian, 1 egyptian, 1 haïtian, 1 senegalese) and one woman (congolese). Twenty eight (28) patients were homosexuals. AIDS was transfusion-associated in two cases. Neurologic complications revealed the disease in 2 cases. Eighteen (18) patients had neurological signs or symptoms before death. Age range at death was 22-58 (mean 38). Brain weight in AIDS (from 1150 gms to 1750 gms-mean 1428 gms) was not statistically different from the mean weight of 100 male patients in the same age range autopsied in the same laboratory during the identical period (mean 1427 gms, standard deviation: 23). Microscopic abnormalities were present in every brain examined. These included non-Hodgkin lymphoma (3 cases), opportunistic infections (21 cases: 13 toxoplasmosis, 4 cytomegalovirus encephalitis, 3 cryptococcal meningitis, 1 infection by mycobacterium avium-intracellulare), and subacute encephalitis (17 cases, 9 isolated, 8 associated with other disorders). The characteristic changes consisted of lympho-monocytic focal infiltrates (so-called microglial nodules) and mild lympho-monocytic perivascular cuffs in 10 cases. Typical giant cells were seen only in one case. Mild demyelinating changes were also seen in only one case. No spinal cord spongiosis, nor Progressive Multifocal Leukoencephalopathy was found. HIV localization was performed on frozen sections utilizing in situ hybridization techniques (2 cases) and immunohistologic techniques (5 cases). HIV, RNA and proteins, was detected in 2 cases with subacute encephalitis. Infected cells were labeled with macrophage markers, and rarely with T4 lymphocyte markers. Infected astrocytes (identified by anti-GFAP serum) or neurons (identified by anti-NSE serum) were never observed. No giant cells were seen in these two cases.
