[Effect of clarithromycin on symptoms and mucociliary transport in patients with sino-bronchial syndrome].
The effect of clarithromycin on symptoms and on mucociliary transport (as assessed by the saccharin test) were studied in 32 patients with sino-bronchial syndrome. Before treatment with clarithromycin, the nasal clearance time was significantly longer in these patients (70.3 +/- 64.7 min, mean +/- SD) than in control subjects (11.9 +/- 5.3 min, p < 0.001). By the end of 4 weeks of treatment with oral clarithromycin (400 mg/day), nasal clearance time in the patients had improved significantly (30.4 +/- 39.5 min, p < 0.001). Before clarithromycin therapy, bacteria were found in cultures of sputum from 15 patients. After clarithromycin therapy, bacteria were found in cultures of sputum from only 3 of those 15 patients. Cough frequency, volume of sputum, and dyspnea on exertion were significantly improved by clarithromycin therapy. These findings suggest that mucociliary transport is abnormal in patients with sino-bronchial syndrome, and that clarithromycin can be clinically useful in these patients.
