High prevalence of bronchiectasis in emphysema-predominant COPD patients.
COPD has been identified as an etiology or related disease of bronchiectasis, and bronchiectasis has been classified as a comorbidity of COPD. In this study, we investigated the prevalence of bronchiectasis in different phenotypes of COPD subjects and the correlation between bronchiectasis and different phenotypes, especially emphysema. ⋯ The proportion of bronchiectasis is higher in emphysema-predominant COPD subjects. Emphysema measured by EI and FEV1% predicted are independent predictors for bronchiectasis in COPD subjects, while the underlying mechanism deserves further investigation.

A novel CT-emphysema index/FEV1 approach of phenotyping COPD to predict mortality.
COPD-associated mortality was examined using a novel approach of phenotyping COPD based on computed tomography (CT)-emphysema index from quantitative CT (QCT) and post-bronchodilator (BD) forced expiratory volume in 1 second (FEV1) in a local Malaysian cohort. ⋯ "Severe mixed airway-emphysema" disease may predict COPD-associated mortality. Age, body mass index, and COPD Assessment Test score remain as key mortality risk factors in our cohort.

Randomized Controlled Trial Multicenter Study Comparative StudyPharmacokinetics of glycopyrronium/formoterol fumarate dihydrate delivered via metered dose inhaler using co-suspension delivery technology in patients with moderate-to-very severe COPD.
The efficacy and tolerability of GFF MDI (Bevespi Aerosphere®), a fixed-dose combination of glycopyrronium (GP)/formoterol fumarate dihydrate (FF) 14.4/10 μg (equivalent to glycopyrrolate/formoterol fumarate 18/9.6 μg) delivered by metered dose inhaler (MDI) using innovative co-suspension delivery technology, has been investigated in a Phase III clinical trial program (NCT01854645, NCT01854658, NCT01970878) in patients with COPD. Here, we present findings from a pharmacokinetic (PK) sub-study of NCT01854645 (PINNACLE-1). ⋯ Overall, the results have characterized the accumulation of glycopyrronium and formoterol associated with GFF MDI, GP MDI, and FF MDI, and indicated that there were no meaningful PK interactions, whether drug-drug or due to formulation, between glycopyrronium and formoterol following treatment with GFF MDI formulated using co-suspension delivery technology.

Randomized Controlled Trial Multicenter Study Comparative StudyThe impact of indacaterol/glycopyrronium fixed-dose combination versus tiotropium monotherapy on lung function and treatment preference: a randomized crossover study - the FAVOR study.
The objective of the FAVOR study was to evaluate the effect of indacaterol/glycopyrronium (IND/GLY) versus tiotropium on peak forced expiratory volume in 1 s (FEV1) and also to investigate patient satisfaction and treatment preference. ⋯ This study indicated that, beyond FEV1, important patient-reported outcomes improved with the open-label dual bronchodilator IND/GLY when compared with tiotropium. This study suggests that individual patients felt the lung function benefits with IND/GLY compared with tiotropium, which, in turn, may also have contributed to the preference for IND/GLY.

Randomized Controlled TrialClinical characteristics of patients newly diagnosed with COPD by the fixed ratio and lower limit of normal criteria: a cross-sectional analysis of the TargetCOPD trial.
Consensus on the definition of airflow obstruction to diagnose COPD remains unresolved. ⋯ In symptomatic individuals, defining airflow obstruction by FR instead of LLN identifies a significant number of individuals who have less respiratory and more cardiac clinical characteristics.
