          Abstract

          Background

          Global Initiative for Chronic Obstructive Lung Disease (GOLD) global strategy (2015) provides guidance for the treatment of chronic obstructive pulmonary disease (COPD) with different first-choice options per GOLD category without specification.

          Objectives

          To evaluate the level of medical experts’ consensus on their preferred first-choice treatment within different COPD categories.

          Methods

          A two-round Delphi Panel consisting of 15 questions was completed by Belgian pulmonologists (n=31) and European (n=10) COPD experts.

          Results

          Good consensus was reached by both expert groups for long-acting bronchodilators instead of short-acting bronchodilators as first-choice treatment in GOLD A. Single bronchodilation with long-acting muscarinic antagonist (LAMA) was preferred over long-acting β2-agonist (LABA) and LABA/LAMA as first-choice treatment in GOLD B and GOLD C. For GOLD D patients based on the forced expiratory volume in 1 second (FEV 1)<50%, a very good consensus was reached for LAMA/LABA as first-choice treatment. For GOLD D patients based on frequent or severe exacerbations, there was a good consensus for LABA/LAMA/inhaled corticosteroids (ICS) as first choice in the Belgian group. According to the European experts, both LABA/LAMA and LABA/LAMA/ICS could be the first choice for these patients.

          Conclusion

          Belgian and European experts recommend long-acting bronchodilators as first-choice treatment. Treatment containing ICS was found only appropriate in patients with FEV 1<50% and ≥2 moderate exacerbations or 1 severe exacerbation/year.

          Characteristics of physical activities in daily life in chronic obstructive pulmonary disease.

          Quantification of physical activities in daily life in patients with chronic obstructive pulmonary disease has increasing clinical interest. However, detailed comparison with healthy subjects is not available. Furthermore, it is unknown whether time spent actively during daily life is related to lung function, muscle force, or maximal and functional exercise capacity. We assessed physical activities and movement intensity with the DynaPort activity monitor in 50 patients (age 64 +/- 7 years; FEV1 43 +/- 18% predicted) and 25 healthy elderly individuals (age 66 +/- 5 years). Patients showed lower walking time (44 +/- 26 vs. 81 +/- 26 minutes/day), standing time (191 +/- 99 vs. 295 +/- 109 minutes/day), and movement intensity during walking (1.8 +/- 0.3 vs. 2.4 +/- 0.5 m/second2; p < 0.0001 for all), as well as higher sitting time (374 +/- 139 vs. 306 +/- 108 minutes/day; p = 0.04) and lying time (87 +/- 97 vs. 29 +/- 33 minutes/day; p = 0.004). Walking time was highly correlated with the 6-minute walking test (r = 0.76, p < 0.0001) and more modestly to maximal exercise capacity, lung function, and muscle force (0.28 < r < 0.64, p < 0.05). Patients with chronic obstructive pulmonary disease are markedly inactive in daily life. Functional exercise capacity is the strongest correlate of physical activities in daily life.

            Clinical Significance of Symptoms in Smokers with Preserved Pulmonary Function.

            Currently, the diagnosis of chronic obstructive pulmonary disease (COPD) requires a ratio of forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) of less than 0.70 as assessed by spirometry after bronchodilator use. However, many smokers who do not meet this definition have respiratory symptoms.

              Tiotropium versus salmeterol for the prevention of exacerbations of COPD.

              Treatment guidelines recommend the use of inhaled long-acting bronchodilators to alleviate symptoms and reduce the risk of exacerbations in patients with moderate-to-very-severe chronic obstructive pulmonary disease (COPD) but do not specify whether a long-acting anticholinergic drug or a β(2)-agonist is the preferred agent. We investigated whether the anticholinergic drug tiotropium is superior to the β(2)-agonist salmeterol in preventing exacerbations of COPD. In a 1-year, randomized, double-blind, double-dummy, parallel-group trial, we compared the effect of treatment with 18 μg of tiotropium once daily with that of 50 μg of salmeterol twice daily on the incidence of moderate or severe exacerbations in patients with moderate-to-very-severe COPD and a history of exacerbations in the preceding year. A total of 7376 patients were randomly assigned to and treated with tiotropium (3707 patients) or salmeterol (3669 patients). Tiotropium, as compared with salmeterol, increased the time to the first exacerbation (187 days vs. 145 days), with a 17% reduction in risk (hazard ratio, 0.83; 95% confidence interval [CI], 0.77 to 0.90; P<0.001). Tiotropium also increased the time to the first severe exacerbation (hazard ratio, 0.72; 95% CI, 0.61 to 0.85; P<0.001), reduced the annual number of moderate or severe exacerbations (0.64 vs. 0.72; rate ratio, 0.89; 95% CI, 0.83 to 0.96; P=0.002), and reduced the annual number of severe exacerbations (0.09 vs. 0.13; rate ratio, 0.73; 95% CI, 0.66 to 0.82; P<0.001). Overall, the incidence of serious adverse events and of adverse events leading to the discontinuation of treatment was similar in the two study groups. There were 64 deaths (1.7%) in the tiotropium group and 78 (2.1%) in the salmeterol group. These results show that, in patients with moderate-to-very-severe COPD, tiotropium is more effective than salmeterol in preventing exacerbations.
