Pulmonary Function Studies in Acute Pulmonary Histoplasmosis
Abstract
We performed follow-up pulmonary function studies on three patients with acute pulmonary histoplasmosis over a period of several months, and found that the disease is benign and usually responds well to treatment or is self-limiting. There are four major changes in lung function, namely a restrictive defect, an impairment of diffusing capacity, stiff lung, and obstruction in small airways. These changes usually lead to disturbance of ventilation-perfusion ratios and impaired gas transport across alveolar capillary membranes, resulting in arterial hypoxemia. There is also hypocapnia from alveolar hyperventilation commonly found in restrictive and stiff lung syndrome.This content is limited to qualifying members.
