Randomized Controlled TrialAssessing efficacy of indacaterol in moderate and severe COPD patients: a 12-week study in an Asian population.
This post hoc analysis evaluated the efficacy of indacaterol, a novel inhaled once-daily long-acting β(2)-agonist, by disease severity (GOLD 2005) in patients with moderate-to-severe COPD from six Asian countries/areas (Hong Kong, India, Japan, Korea, Singapore, Taiwan). ⋯ NCT00794157.

Multicenter StudyThe burden of chronic obstructive pulmonary disease in the Middle East and North Africa: results of the BREATHE study.
COPD is a progressive pulmonary disease which may have a profound impact on general health status and quality of life. This article presents data on the burden of COPD obtained from the BREATHE study in the Middle East, North Africa and Pakistan. This study was a large general population survey of COPD conducted in eleven countries of the region using a standardised methodology. ⋯ Psychological distress was reported by between 42.3% and 53.2% of subjects, depending on the item. In conclusion, the burden of COPD is important, and covers central aspects of daily life. For this reason, physicians should take time to discuss it with their patients, and ensure that the management strategy proposed addresses all their needs.

Review Meta AnalysisIndacaterol therapy in patients with COPD not receiving other maintenance treatment.
Recent findings of rapid lung function decline in younger patients with moderate COPD severity suggest the need for effective early treatment. ⋯ Indacaterol, given to patients with moderate-to-severe COPD not receiving other maintenance treatments, provided effective bronchodilation with significant, clinically relevant improvements in dyspnoea and health status compared with placebo.

Randomized Controlled TrialWalking exercise response to bronchodilation in mild COPD: a randomized trial.
Patients with mild chronic obstructive pulmonary disease (COPD) present abnormal ventilatory mechanics during exercise and may require bronchodilator therapy. However, bronchodilation does not enhance cycling exercise tolerance in these patients whereas walking may be more sensitive to the effects of bronchodilation. ⋯ Bronchodilation did not improve walking endurance in patients with mild COPD despite small physiological benefits of uncertain clinical relevance.

Multicenter StudyManagement of chronic obstructive pulmonary disease in the Middle East and North Africa: results of the BREATHE study.
Chronic obstructive pulmonary disease (COPD) is a potentially severe chronic progressive respiratory condition requiring long-term treatment and frequently involving episodic hospitalisations to manage exacerbations. The objective of this analysis was to document diagnosis, evaluation, treatment and management of COPD-related respiratory symptoms in 1,392 subjects fulfilling an epidemiological definition of COPD identified in a general population sample of 62,086 individuals aged ≥ 40 years in ten countries in the Middle East and North Africa region (Algeria, Egypt, Jordan, Lebanon, Morocco, Saudi Arabia, Syria, Tunisia, Turkey and United Arab Emirates), together with Pakistan. 442 subjects (31.8%) claimed to have received a diagnosis of COPD from a physician and 287 (20.6%) had undergone spirometry in the previous year. Use of specific treatments for respiratory symptoms was reported by 218 subjects (15.7%). ⋯ Use of all healthcare resources was significantly higher (p < 0.001) in subjects with CAT scores ≥ 10 than in those with scores < 10, and greater in those with exacerbations than in those without. In conclusion, COPD in the region is under-diagnosed, inadequately evaluated and inadequately treated. Nonetheless, COPD symptoms are responsible for considerable healthcare consumption, with high levels of physician consultation and hospitalisation.
