Abstract | BACKGROUND:
Macrolides are antibiotics that have anti-inflammatory activities. Hence, they are used for both acute and chronic inflammatory airway diseases. However, the effects of these agents on allergic airway disorders presenting with an isolated chronic cough, such as non-asthmatic eosinophilic bronchitis and eosinophilic tracheobronchitis with cough hypersensitivity (atopic cough), still remain to be elucidated. OBJECTIVE: METHODS: The cough reflex sensitivity to inhaled capsaicin was measured at 48h after challenge with an aerosolized antigen in actively sensitized guinea pigs. The 14-, 15- or 16-membered macrolides ( erythromycin, azythromycin, or josamycin, respectively) were given intraperitoneally every 12h after the antigen challenge. Bronchoalveolar lavage and the resection of the tracheal tissue were performed immediately after the measurement of the cough response to capsaicin. RESULTS: CONCLUSIONS:
