Bronchiolitis obliterans organizing pneumonia as an initial manifestation in patients with systemic lupus erythematosus

Abstract

Abstract

Diverse pleuropulmonary manifestations including diaphragmatic dysfunction, pleural effusion, acute lupus pneumonitis, pulmonary hemorrhage, pulmonary hypertension, and diffuse interstitial lung disease have been described in patients with systemic lupus erythematosus (SLE). Bronchiolitis obliterans organizing pneumonia (BOOP) as an initial manifestation of SLE is rarely reported. We describe 2 patients who had SLE concurrent with the onset of BOOP. Their respiratory symptoms, followup pulmonary function tests, and radiologic findings showed much improvement after steroid therapy.
