Paracoccidioidomycosis in patients with human immunodeficiency virus: review of 12 cases observed in an endemic region in Brazil.

OBJECTIVE: To study the clinical characteristics of 12 patients with paracoccidioidomycosis (PCM) and human immunodeficiency virus (HIV) infection.

METHODS: The clinical manifestations, diagnosis, treatment, and outcome of PCM in 12 patients infected with HIV attended at a University Hospital of Mato Grosso do Sul, Brazil, were evaluated.

RESULTS: All patients were men, mean age 36.1 years old, and 11 had a diagnosis other than PCM as the aids-defining illness. Lymph nodes were the organs most often involved (10 patients, 83.3%), followed by lung involvement, usually with an interstitial pattern (seven patients, 58.3%), papule-nodular skin lesions with central ulceration in six (50%) and ulcerated lesions of oral mucous membrane in five (41.6%) patients. Pleural involvement occurred in one patient who presented large pleural effusion beside a pathologic rib fracture caused by P. brasiliensis. Seven patients showed involvement in more than one extrapulmonary organ. In eight (66.6%) cases the diagnosis was established by direct microscopy of clinical specimens. All patients used trimethoprim-sulfamethoxazole and seven patients were also treated with amphotericin B. Eight patients died with progressive PCM manifestations.

CONCLUSION: Our review demonstrates that PCM, an endemic systemic mycosis in Brazil, when associated with AIDS, behaves clinically as an opportunistic disease.
