Abstract

Histoplasmosis occurs in 5–10% of HIV-infected patients in endemic areas and evolves to severe and disseminated infection with mortality rates over 50% in some regions. This report presents epidemiological, clinical and outcome data from HIV-infected patients with histoplasmosis confirmed by culture and/or at necropsy who were admitted to a Brazilian teaching hospital. Data from 65 patients were obtained from their respective medical and necropsy records. From 2005 to 2018, 36 HIV-infected patients were diagnosed with histoplasmosis confirmed by culture. At admission, most of these patients presented disseminated fungal infection, whereas 15 (41.7%) were simultaneously diagnosed with both HIV infection and histoplasmosis. Fever, weight loss, hepatosplenomegaly, respiratory and digestive symptoms were present in 86.2%, 50%, 44.4% and 41.7% of the patients, respectively. At admission, 24 patients had low CD4 T-cell count and high viral load values. Among the 30 patients who received antifungals, 16 (53.3%) were cured, 13 (43.3%) died, and one was lost to follow-up. Six patients died prior to therapy. From 1990 to 2018, 63 necropsies of patients with Histoplasma capsulatum infection were performed. Of these patients, 29 (46.0%) were HIV-infected individuals, including 21 (72.4%) who presented disseminated histoplasmosis and 21 (72.4%) who were diagnosed with histoplasmosis at necropsy. The epidemiological, clinical and outcome profiles presented herein are similar to those described elsewhere and reinforce the difficulties that are still present in limited-resource settings where advanced immunodeficiency, combined with severe fungal infection and late patient admissions, is related to poor outcomes.
