Adult Respiratory Distress Syndrome in Patients with Severe Neutropenia

Abstract

Most investigators believe that the pulmonary endothelial damage that is characteristic of the adult respiratory distress syndrome (ARDS) requires the action of neutrophils. In a retrospective review of patients with ARDS, we looked for cases that had developed in patients who already had neutropenia. Four clinical criteria were required for the diagnosis of ARDS: the occurrence of a precipitating event, diffuse bilateral pulmonary infiltrates on a chest x-ray film, a normal intravascular volume (as reflected by a wedge pressure of less than 18 mm Hg), and arterial hypoxemia.
