Randomized Controlled Trial Multicenter StudyEfficacy and safety of combining olodaterol Respimat(®) and tiotropium HandiHaler(®) in patients with COPD: results of two randomized, double-blind, active-controlled studies.
Combining bronchodilators with different mechanisms of action may improve efficacy and reduce risk of side effects compared to increasing the dose of a single agent in chronic obstructive pulmonary disease (COPD). We investigated this by combining two long-acting bronchodilators: once-daily muscarinic antagonist tiotropium and once-daily β2-agonist olodaterol. ⋯ These studies demonstrated that olodaterol (Respimat(®)) and tiotropium (HandiHaler(®)) provided bronchodilatory effects above tiotropium alone in patients with COPD. In general, both treatments were well tolerated.

Randomized Controlled Trial Multicenter Study Comparative StudyLung function efficacy and symptomatic benefit of olodaterol once daily delivered via Respimat® versus placebo and formoterol twice daily in patients with GOLD 2-4 COPD: results from two replicate 48-week studies.
Two replicate, multicenter, randomized, double-blind, placebo-controlled, parallel-group, Phase III studies investigated the long-term efficacy and safety of once-daily olodaterol via Respimat® versus placebo and formoterol over 48 weeks in patients with moderate to very severe chronic obstructive pulmonary disease receiving usual-care background therapy. Patients received once-daily olodaterol 5 or 10 μg, twice-daily formoterol 12 μg, or placebo. Co-primary end points were forced expiratory volume in 1 second (FEV1) area under the curve from 0-3 hours response, FEV1 trough response, and Mahler transition dyspnea index total score after 24 weeks; secondary end points included St George's Respiratory Questionnaire. ⋯ St George's Respiratory Questionnaire total score was significantly improved with olodaterol, but not formoterol, versus placebo. No safety signals were identified from adverse-event or other safety data. Once-daily olodaterol 5 μg and 10 μg is efficacious in patients with moderate to very severe chronic obstructive pulmonary disease on usual-care maintenance therapy, with a satisfactory safety profile.

Review Practice GuidelineExpert consensus on acute exacerbation of chronic obstructive pulmonary disease in the People's Republic of China.
Chronic obstructive pulmonary disease (COPD) is a common disease that severely threatens human health. Acute exacerbation of COPD (AECOPD) is a major cause of disease progression and death, and causes huge medical expenditures. This consensus statement represents a description of clinical features of AECOPD in the People's Republic of China and a set of recommendations. It is intended to provide clinical guidelines for community physicians, pulmonologists and other health care providers for the prevention, diagnosis, and treatment of AECOPD.

Meta AnalysisRoflumilast and dyspnea in patients with moderate to very severe chronic obstructive pulmonary disease: a pooled analysis of four clinical trials.
Breathlessness is a predominant symptom of chronic obstructive pulmonary disease (COPD), making it a valuable outcome in addition to lung function to assess treatment benefit. The phosphodiesterase-4 inhibitor roflumilast has been shown to provide small but significant improvements in dyspnea, as measured by the transition dyspnea index (TDI), in two 1-year studies in patients with severe to very severe COPD. ⋯ This analysis shows that patients treated with roflumilast to reduce exacerbation risk may also experience small but significant improvements in dyspnea, with accompanying improvements in lung function.

Multicenter Study Comparative StudyExperience of fatigue, and its relationship to physical capacity and disease severity in men and women with COPD.
Several differences have been reported in the clinical characteristics of chronic obstructive pulmonary disease (COPD) between men and women. Differences have been found in the association between respiratory symptoms and lung function, and in the factors associated with dyspnea. This raises the question of whether there are differences between the sexes in the relationship between fatigue, the second most prevalent symptom, and the variables of physical capacity and disease severity. ⋯ Exercise capacity and disease severity were associated with fatigue in both men and women. In women, leg fatigue was strongly associated with fatigue, which warrants further investigation.
