AIDS-related disseminated histoplasmosis in San Francisco, California.

Abstract

The published reports of patients with the acquired immunodeficiency syndrome (AIDS) with disseminated histoplasmosis come mostly from institutions located in endemic areas for histoplasmosis, where disease is thought to occur by either primary infection or reactivation. The characteristics of reactivation disease are not well delineated. We describe the clinical features of reactivation disseminated histoplasmosis in 46 residents of San Francisco, California, with AIDS who did not report recent travel to an area endemic for histoplasmosis. Patients presented with illness lasting days to months, manifested most frequently by fever, chills, sweats, cough or dyspnea, gastrointestinal complaints, malaise, and weight loss. Physical examination and imaging studies were notable for hepatosplenomegaly, lymphadenopathy, or abnormal pulmonary findings in more than half of patients. Laboratory studies revealed a high rate of cytopenia, elevated serum lactate dehydrogenase levels, abnormal liver function test values, respiratory alkalosis with hypoxemia, and a median CD4 lymphocyte count of 36 x 10(9) per liter. The clinical presentation of reactivation disseminated histoplasmosis in patients with AIDS living in San Francisco is similar to that of disseminated histoplasmosis reported in patients with AIDS living in endemic areas. Reactivation disseminated histoplasmosis should be considered in any AIDS patient with a low CD4 lymphocyte count, a febrile illness, and a history of travel or residence in an endemic area.
