Identification of fungal diseases at necropsy.

The purpose of the Death Verification Service is to elucidate the causes of deaths that occur without medical assistance and of ill-defined deaths. In recent decades, the epidemiological reality of fungal infections has changed due to the rise in opportunistic infections chiefly in immunocompromised patients. A study of fungal diseases in autopsies performed in the Death Verification Service of the Medicine School in São José do Rio Preto between January 2000 and December 2009 was made. Sixty-seven cases of fungal disease, most involving men (70%), were found in 4824 autopsies. Cryptococcosis was the most prevalent (45%), followed by paracoccidioidomycosis, candidiasis, histoplasmosis, aspergillosis and mucormycosis. Associations between AIDS (n=14) and fungal diseases were identified for cryptococcosis (36%), candidiasis (28.5%) and histoplasmosis (28.5%). Pneumonia, AIDS and fungal diseases were evident in 26% of the cases, with the most prevalent etiologies being Cryptococcus neoformans (55.5%) and Histoplasma capsulatum (22%). Pneumonia alone occurred in 43% of cases, with cryptococcosis (53%) and paracoccidioidomycosis (33%) being the main infectious agents. Diabetes mellitus was associated with candidiasis in two cases and aspergillosis in one. One case of renal transplantation linked to paracoccidioidomycosis and one case of bone marrow aplasia with mucormycosis were reported. Despite the reduction in the number of autopsies over recent decades, these findings suggest that this procedure is useful to provide additional data on the etiology, underlying disease and specific risk factors, essential for quality control and to improve treatment protocols.
