[Effect of erythromycin on mucociliary transport and clinical symptoms in patients with sinobronchial syndrome].
The effect of erythromycin (EM) on mucociliary transport function assessed by saccharin test and clinical symptoms were studied in 19 patients with sinobronchial syndrome (SBS). Before treatment with EM, the mean nasal clearance time (NCT) of SBS patients was 51.9 +/- 40.5 (SD) min, which was significantly (p < 0.01) longer than that of control subjects (12.4 +/- 5.3 min). After 4-week treatment with oral EM (600 mg/day), NCT of SBS patients significantly (p < 0.01) improved (29.2 +/- 34.2 min). In 11 of 19 SBS patients, bacteria from sputum culture disappeared after EM therapy. Frequency of cough and volume of sputum were significantly (p < 0.05) decreased by EM therapy. Nasal symptoms (such as nasal obstruction and rhinorrhea) were also significantly (p < 0.05) improved by EM therapy. These findings suggested that disorder of mucociliary transport function was present in patients with SBS, and EM therapy improved this function. EM clinically improved not only the lower airway symptoms, but also the nasal symptoms.
