Objective: To evaluate the correlation between clinical and autopsy findings in 250 AIDS patients.
Methods: Clinical and autopsy diagnoses of AIDS-defining diseases in 250 AIDS patients who died in Milan between May 1984 and February 1991 were compared.
Results: Pneumocystis carinii (PCP) and oesophageal candidiasis were the most frequent clinical diagnoses, while cytomegalovirus (CMV) infection was observed in almost half of the autopsies. Forty-seven per cent of the diseases found at autopsy had not been diagnosed during life; CMV infection, mycoses, HIV-specific brain lesions, cerebral lymphomas and progressive multifocal leukoencephalopathy (PML) had a higher rate of non-diagnosis in life. CMV visceral infection accounted for the majority of the diseases not recognized in life. In contrast, clinically diagnosed PCP, oesophageal candidiasis and, to a lesser degree, brain toxoplasmosis were often not found at autopsy, possibly indicating a significant rate of recovery and prevention of relapse. Finally, bacterial pneumonia and sepsis, although not AIDS indicator diseases, were observed in approximately one-third of the autopsies.
Conclusion: Considerable differences in the frequency and type of the AIDS-defining diseases diagnosed during life and at post mortem were found.
