Low-dose amphotericin B therapy for acute pulmonary histoplasmosis

A patient wtih acute epidemic pulmonary histoplasmosis was treated with 500 mg of amphotericin B. Traditionally, such patients have not been treated, since the illness is usually self-limited; however, fatalities have been reported, and some authorities have recommended therapy with small doses of amphotericin B. Patients with acute pulmonary histoplasmosis who are acutely ill should be considered for low-dose treatment with amphotericin B, inasmuch as they are likely candidates for early dissemination. Cures have been reported with as little as 105 mg of amphotericin B administered intravenously.
