Abstract :

Rationale: Eosinophil infl ammation in the airways is observed in some patients with chronic obstructive pulmonary disease (COPD) independent of asthma. However, little is known about not only mechanisms but also therapy in this clinical phenotype of COPD. Th is clinical study was designed to determine whether inhaled glucocorticosteroids (ICS) are useful for airway eosinophilia in COPD. Methods: Once-daily inhalation of indacaterol (LABA) was fi rstly administrated to the patient with COPD. Aft er symptoms were stable, sputum examination was done. When a percentage of eosinophil in the induction sputum is >3%, once-daily inhalation of ciclesonide (ICS) was administered. Results: 20 patients with COPD (GOLD 2-3) with airway eosinophilia were enrolled. Aft er administration of indacaterol, COPD Assessment Test (CAT) score was decreased from 15.1 to 7.9 (P<0.05), and frequency of SABA on demand for symptom relief was also decreased from 1.6 to 0.8 puff s/week (P<0.05). In lung function test, forced expiratory volume in 1 sec (FEV1) and inspiratory capacity (IC) were increased by 210.0 (P<0.05) and 311.5 mL (P<0.01), respectively. Aft er addition to ciclesonide, values of CAT score and frequency of SABA were markedly decreased to 4.9 points and 0.3 puff s/week, respectively (each P<0.05 vs. LABA). Moreover, FEV1 and IC were further increased by 147.0 and 227.6 mL, respectively (each P<0.05 vs. LABA). Conclusions: Not only LABA but also ICS is needed to improve lung function and to achieve better maintenance in COPD with airway eosinophilia. Ciclesonide is eff ective for these cases. Eosinophil infi ltration to airways may be indication of ICS therapy for COPD.
