Acute pulmonary histoplasmosis presenting as adult respiratory distress syndrome: effect of therapy on clinical and laboratory features.
Three patients with acute pulmonary histoplasmosis presented with extensive, diffuse bilateral infiltrates on chest roentgenograms. Fungal elements were seen in the bronchial secretions of two patients; Histoplasma capsulatum was grown from the third patient and from soil from the patients' workplace. Two patients were severely hypoxemic and required short courses of amphotericin B therapy; in one of these two, progressive deterioration dictated corticosteroid therapy as well, with a dramatic clinical response. Radiologic resolution of disease occurred more quickly in the treated patients. Initial pulmonary function tests suggested mild restriction in each, with normal test results by the fourth month of follow-up. Our experience suggests that amphotericin B may shorten the course of acute histoplasmosis and that corticosteroid therapy may be efficacious in controlling the symptoms related to hyperresponsiveness in fulminant primary disease.
