Oral treatment of paracoccidioidomycosis and histoplasmosis with itraconazole in humans

Abstract

Twenty-five patients with paracoccidioidomycosis and 17 patients with histoplasmosis were treated with itraconazole. All patients were adults. Those with paracoccidioidomycosis exhibited the chronic disseminated form of the disease; 21 of these patients had lesions in two or more locations, and four had lesions only on the larynx or mouth. Itraconazole was administered at a daily dosage of 50 mg for six months in the majority of these cases. All infections were clinically cured or showed striking improvement. Patients with histoplasmosis had the chronic pulmonary or chronic disseminated form of the disease. A daily dose of 100 mg was administered until clinical cure was established; the dose was then changed to 50 mg until the completion of six months of treatment. Twelve infections were clinically cured; four were strikingly alleviated. The remaining patient, who discontinued treatment with itraconazole after two months, had a severe relapse and died of respiratory failure.
