Pulmonary function in patients with endobronchial sarcoidosis

Acta Med Scand. 1984;215(2):121-6. doi: 10.1111/j.0954-6820.1984.tb04981.x.

Abstract

Sixty-four patients with clinically, radiologically and histopathologically established sarcoidosis were studied by bronchoscopy and static and dynamic spirometry. Sarcoid bronchostenosis was established by bronchoscopy in nine patients. Twenty-one had bronchial sarcoidosis without stenosis and 34 had no evidence of bronchial sarcoidosis. Patients with sarcoid bronchostenosis showed a marked impairment of lung function, mostly with an obstructive pattern. There was no improvement in lung function after bronchodilatation in these patients. Obstructive spirometry pattern was also found in three patients with bronchial sarcoidosis stage II without stenosis. None of the patients without bronchial sarcoidosis had an obstructive pattern. All six patients with restrictive spirometry pattern in the two groups without bronchostenosis had stage II sarcoidosis. At follow-up, lung function had improved in five patients, four with sarcoid bronchostenosis and one patient with stage II without bronchial sarcoidosis. Four of these patients were treated with oral corticosteroids. When clinical signs of airway obstruction are present in patients with sarcoidosis, bronchial sarcoidosis with or without bronchostenosis should be suspected. When bronchial sarcoidosis is present, oral corticosteroid treatment should be tried.
