Tracheobronchial clearance in patients with pulmonary sarcoidosis

Lung mucociliary clearance was measured using an objective, noninvasive radioaerosol technique in 13 patients with pulmonary sarcoidosis and 13 matched, healthy control subjects. Four of the sarcoid patients had never received any steroid therapy, five were currently receiving oral corticosteroids,...

Summary:Lung mucociliary clearance was measured using an objective, noninvasive radioaerosol technique in 13 patients with pulmonary sarcoidosis and 13 matched, healthy control subjects. Four of the sarcoid patients had never received any steroid therapy, five were currently receiving oral corticosteroids, and the remaining four were using inhaled corticosteroids only. A statistically significant retardation in tracheobronchial clearance (p less than 0.02) was observed in the sarcoid patients compared to the control subjects. The sarcoid patients using inhaled corticosteroids appeared to demonstrate the greatest degree of mucociliary transport impairment. The sarcoid patients in apparent remission and those receiving oral corticosteroid therapy had clearances better than those using inhaled corticosteroids, but they were still reduced compared to the control subjects. This study demonstrates that lung mucociliary clearance is adversely affected in patients with pulmonary sarcoidosis and raises the question of the possible consequences that could follow long-term inhaled immunosuppressive therapy on the prime clearance defense mechanism within the human lungs.
