[Clinical picture of the onset of AIDS in 2911 adults in Italy].

Since 1982, 2911 adult AIDS cases have been officially reported in Italy up to December 31, 1988. The clinical presentation of all cases, reported to the Istituto Superiore di Sanità, Rome, and contained into the National AIDS Register, has been analyzed, with particular attention to opportunistic infections. 168 cases (mainly homosexual men) were found exclusively affected at diagnosis by Kaposi's Sarcoma (KS), while the other 2743 patients were affected by opportunistic infections and/or other pathologies. At diagnosis, 23.5% of patients had Pneumocystis carinii pneumonia (PCP), 32% esophageal or pulmonary candidiasis, and 7% cerebral toxoplasmosis. A decrease in frequency of Cytomegalovirus (CMV) diseases has been observed, as well as an increase of HIV encephalopathy from 1982 to 1988. The clinical picture of full-blown AIDS showed stability during the whole period of observation, with slight geographical variations.
