Patho-anatomical studies in patients dying of AIDS.

Abstract

The incidence of AIDS in Denmark is the highest reported among the countries of Western Europe. This preliminary account is a report of the autopsy findings in 10 patients, 9 homosexual men and 1 woman. Our aim is to provide a detailed description of the patho-anatomical findings, as well as to compare these with corresponding results reported from the United States, with a view to establishing possible geographical differences in the disease picture. The results of the patho-anatomical studies correspond in all essentials to those from the United States. However, it must be stated that no malignant lymphomas were demonstrated in our patients, although the disease can give rise to very pronounced, possibly transitory, lesions in the lymphatic tissue, easily misinterpreted as malignant. Further features that should be emphasized are the often widespread mycobacterial infection found in the intestinal wall in protracted cases, the occurrence of CMV vasculitis, particularly in the adrenal cortex and medulla, and thromboembolic lesions, often demonstrated in a variety of tissues. The studies made so far emphasize the importance of autopsy in AIDS deaths, as it has extended our detailed knowledge of the patho-anatomical lesions associated with certain opportunistic infections. Further, the autopsy findings have been demonstrably significant either for confirming or for rejecting the clinical diagnosis. On the basis of an analysis of the cellular immunological profile in AIDS, parallels can be drawn to the conditions in certain lymphoproliferative diseases. In autopsied AIDS cases, we recommend a standard scheme covering the tissue specimens to be obtained for histological examination. Strict safety precautions should be observed against infection during autopsy.
