ReviewMaintenance therapy in COPD: time to phase out ICS and switch to the new LAMA/LABA inhalers?
Long-term maintenance therapy for COPD is evolving rapidly. Dual bronchodilation with new long-acting muscarinic antagonist and long-acting beta-agonist (LAMA/LABA) fixed dose combination inhalers were introduced over the past 2 years. In clinical trials, these inhalers significantly improved lung function (trough forced expiratory volume in 1 second), patient-reported outcomes, and quality of life measures compared with placebo, their respective monocomponents, and tiotropium. ⋯ Recent studies compared these LAMA/LABA inhalers with ICS/LABA combination inhalers in moderate-to-severe COPD. The results are promising and favor the LAMA/LABA inhalers, especially in the longer duration trials. Furthermore, there is a clearer picture emerging as to the subgroup of COPD patients who may be able to successfully switch from their current ICS/LABA therapy to these new LAMA/LABA inhalers.

ReviewSpotlight on fluticasone furoate/umeclidinium/vilanterol in COPD: design, development, and potential place in therapy.
COPD is characterized by persistent airflow obstruction caused by exposure to irritants including cigarette smoke, dust, and fumes. According to the latest GOLD (Global Initiative for Chronic Obstructive Lung Disease) guidelines, a combination of inhaled corticosteroids, long-acting β2 agonists, and long-acting muscarinic receptor antagonists can be used for group D COPD patients who are at high risk for exacerbations. Umeclidinium/fluticasone furoate/vilanterol is one such triple-combination therapy currently under development with some completed and several ongoing clinical trials. This review paper summarizes the pharmacologic profiles of these medications and highlights findings from clinical trials, including safety and efficacy data, while speculating on the role of this therapy in current treatment for COPD.

Multicenter Study Observational StudyAdherence to a COPD treatment guideline among patients in Hong Kong.
This study aimed to assess the adherence rate of pharmacological treatment to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guideline published in 2011 and the prevalence of comorbidities among patients with COPD in Hong Kong (HK). ⋯ A suboptimal adherence to GOLD guideline 2011, with overprescription of ICS, was identified. The commonly found comorbidities also aligned with the trend observed in other observational cohorts.

Multicenter StudyRisk factors for the discontinuation of roflumilast in patients with chronic obstructive pulmonary disease.
Roflumilast is a phosphodiesterase-4 inhibitor, which can decrease exacerbation in patients with chronic obstructive pulmonary disease (COPD). However, adverse effects are a major barrier to medication use, and little is known regarding the risk factors for discontinuation of roflumilast in COPD patients. ⋯ The patient discontinuation and adverse events rates in this study were higher than in previous randomized controlled studies. Discontinuation of roflumilast in ethnic Koreans is more likely to occur in low-BMI patients. In a clinical setting, low-BMI patients can more easily discontinue roflumilast; clinicians should, therefore, provide greater care for these patients.

Multicenter Study Observational StudyPredicting high risk of exacerbations in bronchiectasis: the E-FACED score.
Although the FACED score has demonstrated a great prognostic capacity in bronchiectasis, it does not include the number or severity of exacerbations as a separate variable, which is important in the natural history of these patients. ⋯ E-FACED score significantly increases the FACED capacity to predict future yearly exacerbations while maintaining the score's simplicity and prognostic capacity for death.
