ABSTRACT
Systemic corticosteroids and additional short-acting beta2-agonists are commonly used in exacerbations of chronic obstructive pulmonary disease (COPD). In this double-blind study, the combination of a high-dose inhaled corticosteroid with a rapid-onset long-acting beta2-agonist was evaluated in the treatment of out-patient COPD exacerbations. The primary aim was to compare 14-day treatment effects of budesonide/formoterol to placebo on sputum eosinophils and, secondarily, on other indices of inflammation, forced expiratory flow in one second (FEV(1)), symptoms, health status, and adverse events. Forty-five patients not using steroids (37 male, 21/24 current/ex smoker, median packyears 38, age 65 years, FEV(1) 61% predicted), experiencing a COPD exacerbation, were treated at home with budesonide/formoterol (320/9 microg 4 times daily), prednisolone (30 mg daily), or placebo for 14 days. Sputum eosinophils were significantly reduced by budesonide/formoterol (-57%) compared to placebo (+24%) (p = 0.01). Budesonide/formoterol reduced total symptom scores significantly (p = 0.01) compared to placebo. The increase in FEV(1) by 2 weeks of treatment with budesonide/formoterol (125 ml) was not significantly different from that of placebo (43 ml) (p = 0.07). Budesonide/ formoterol treatment did not suppress morning serum cortisol compared to placebo (-16%; p = 0.50). In conclusion, budesonide/formoterol reduces sputum eosinophils and improves symptoms in the treatment of out-patient COPD exacerbations.
