Abstract

The aim of this double-blind single center study (the COPE study) was to investigate the effect of discontinuation of the inhaled corticosteroid fluticasone propionate (FP) on exacerbations and health-related quality of life in patients with chronic obstructive pulmonary disease. After 4 months of treatment with FP (1,000 μg/day), 244 patients were randomized to either continue FP or to receive placebo for 6 months: 123 patients continued FP (FP group), and 121 received placebo (placebo group). In the FP group, 58 (47%) patients developed at least one exacerbation compared with 69 (57%) in the placebo group. The hazard ratio of a first exacerbation in the placebo group compared with the FP group was 1.5 (95% confidence interval [CI] 1.1–2.1). In the placebo group 26 patients (21.5%) experienced rapid recurrent exacerbations and were subsequently unblinded and prescribed FP compared with 6 patients (4.9%) in the FP group (relative risk = 4.4; 95% CI 1.9–10.3). Over a 6-month period, a significant difference in favor of the FP group was observed in the total score (+2.48 95% CI 0.37–4.58), activity domain (+4.64 95% CI 1.60–7.68), and symptom domain (+4.58 95% CI 1.05–8.10) of the St. George's Respiratory Questionnaire. This study indicates that discontinuation of FP in patients with chronic obstructive pulmonary disease is associated with a more rapid onset and higher recurrence-risk of exacerbations and a significant deterioration in aspects of Health-Related Quality of Life.
