PARACOCCIDIOIDOMYCOSIS AND AIDS - AN OVERVIEW

The scarcity of reported cases of paracoccidioidomycosis and AIDS remains unexplained. We review the details of the 27 cases reported in the medical literature. Paracoccidioidomycosis occurs in patients with advanced AIDS who are not receiving prophylaxis for Pneumocystis carinii pneumonia with trimethoprim-sulfamethoxazole, which is also effective against Paracoccidioides brasiliensis. Clinical manifestations include prolonged fever, weight loss, generalized lymphadenopathy, splenomegaly, hepatomegaly, and skin rash. Diagnosis can often be made by direct microscopic examination and culture of the fungus from skin and lymph node specimens and occasionally from sputum, blood, spinal fluid, and bone marrow specimens. Since antibodies to P. brasiliensis are occasionally detected, the diagnosis should not be ruled out for patients whose serology is negative. Despite specific therapy with different regimens, the overall mortality of paracoccidioidomycosis among patients with AIDS is high (30%). The prognosis can be improved by earlier diagnosis and aggressive therapy with amphotericin B, followed by lifelong immunosuppressive therapy with trimethoprimsulfamethoxazole. Health care providers caring for human immunodeficiency virus-infected patients who live or have resided in areas in which paracoccidioidomycosis is endemic must be aware of the possibility that this systemic mycosis may occur and have potentially severe consequences.
