Abstract

We reviewed the clinical, microbiologic, and outcome characteristics of 72 patients with human immunodeficiency virus (HIV)-associated histoplasmosis (4 newly described) reported in Europe over 20 years (1984-2004). Seven cases (9.7\%) were acquired in Europe (autochthonous), whereas the majority involved a history of travel or arrival from endemic areas. The diagnosis of progressive disseminated histoplasmosis (PDH) was made during life in 63 patients (87.5\%) and was the acquired immunodeficiency syndrome (AIDS)-presenting illness in 44 (61.1\%). Disease was widespread in 66 patients (91.7\%) and localized in 6 (8.3\%), with the skin being the most frequent site of localized infection. Overall skin involvement was reported in 47.2\% of the patients regardless of whether histoplasmosis was acquired in Africa or South America. Reticulonodular or diffuse interstial infiltrates occurred in 52.8\%. The diagnosis was made during life by histopathology plus culture in 44 patients (69.8\%), histopathology alone in 18 (28.5\%), and culture alone in 1 (1.5\%). During the induction phase amphotericin B and itraconazole (74.6\%) were the single most frequently used drugs. Both drugs were also used either in combination (10.2\%) or in sequential therapy (11.8\%). Cumulative mortality rate during the induction phase of treatment was 15.2\%. Overall, 37 patients died (57.8\%); death occurred early in the course in 18 (28.1\%). Seven of 40 patients (17.5\%) who responded to therapy subsequently relapsed. Autopsy data in 13 patients confirmed the widespread disseminated nature of histoplasmosis (85\%) among AIDS patients with a median of 4.5 organs involved. The results of the present report highlight the need to consider the diagnosis of PDH among patients with AIDS in Europe presenting with a febrile illness who have traveled to or who originated from an endemic area.
