ABSTRACT
Background: Guidelines recommend inhaled corticosteroids (ICS) as maintenance treatment for patients with chronic obstructive pulmonary disease (COPD) with a post-bronchodilator forced expiratory volume in 1 second (FEV1) <50% predicted and frequent exacerbations, although they have only a small preventive effect on the accelerated decline in lung function. Combined treatment with ICS and long acting 132 agonists (LABA) may provide benefit to the stability of COPD, but it is unknown if withdrawal of CS will result in disease deterioration. Methods: The effects of 1 year withdrawal of the ICS fluticasone propionate (FP) after a 3 month run-in treatment period with FP combined with the LABA salmeterol (S) (500 μg FP +50 μg S twice daily; SFC) were investigated in patients with COPD in a randomised, double blind study. 497 patients were enrolled from 39 centres throughout the Netherlands; 373 were randomised and 293 completed the study. Results: The drop out rate after randomisation was similar in the two groups. Withdrawal of FR resulted in a sustained decrease in FEV1: mean (SE) change from baseline -4.4 (0.9)% (S) v -0.1 (0.9)% (SFC); adjusted difference 4.1 (95% CI 1.6 to 6.6) percentage points (p<0.001). Corresponding figures for the FEV1/FVC ratio were -3.7 (0.8)% (5) v 0.0 (0.8)% (SFC) (p=0.002). The annual moderate to severe exacerbation rate was 1.6 and 1.3 in the S and SFC groups, respectively (adjusted rate ratio 1.2; 95% CI 0.9 to 1.5; p =0.15). The mean annual incidence rate of mild exacerbations was 1.3 (5) v 0.6 (SFC), p =0.020. An immediate and sustained increase in dyspnoea score (scale 0-4; mean difference between groups 0.17 (0.04), p<0.001) and in the percentage of disturbed nights (6 (2) percentage points, p<0.001) occurred after withdrawal of fluticasone. Conclusions: Withdrawal of FP in COPD patients using SFC resulted in acute and persistent deterioration in lung function and dyspnoea and in an increase in mild exacerbations and percentage of disturbed nights. This study clearly indicates a key role for ICS in the management of COPD as their discontinuation leads to disease deterioration, even under treatment with a LABA.
