How can the findings of the EMAX trial on long-acting bronchodilation in chronic obstructive pulmonary disease be applied in the primary care setting?

This review addresses outstanding questions regarding initial pharmacological management of chronic obstructive pulmonary disease (COPD). Optimizing initial treatment improves clinical outcomes in symptomatic patients, including those with low exacerbation risk. Long-acting muscarinic antagonist/long-acting β-agonist (LAMA/LABA) dual therapy improves lung function versus LAMA or LABA monotherapy, although other treatment benefits have been less consistently observed.

Applying key learnings from the EMAX trial to clinical practice and future trial design in COPD.

Early MAXimisation of bronchodilation for improving COPD stability (EMAX) was a large, multicentre, multi-national, randomised, double-blind, 24-week trial. EMAX evaluated the efficacy and safety of dual bronchodilator therapy with umeclidinium bromide (UMEC)/vilanterol (VI) versus monotherapy with either UMEC or salmeterol (SAL) in symptomatic patients with chronic obstructive pulmonary disease (COPD) at low exacerbation risk who were not taking concomitant inhaled corticosteroid (ICS). EMAX generated evidence covering a wide range of patient-centred endpoints in COPD in addition to measures of lung function, clinical deterioration and safety.

Dual Bronchodilator Therapy as First-Line Treatment in Maintenance-Naïve Patients with Symptomatic COPD: A Pre-Specified Analysis of the EMAX Trial.

Introduction: Limited prospective evidence is available to guide selection of first-line maintenance therapy in patients with COPD. This pre-specified analysis of the EMAX trial explored the efficacy and safety of dual- versus mono-bronchodilator therapy in maintenance-naïve and maintenance-treated patients.

Methods: The 24-week EMAX trial evaluated lung function, symptoms (including rescue medication use), exacerbations, and safety with umeclidinium/vilanterol, umeclidinium, and salmeterol in symptomatic patients at low exacerbation risk who were not receiving inhaled corticosteroids.

Treatment of COPD with Long-Acting Bronchodilators: Association Between Early and Longer-Term Clinically Important Improvement.

Introduction: This post hoc analysis of the "Early MAXimization of bronchodilation for improving COPD stability" (EMAX) trial investigated whether patients achieving early clinically important improvement (CII) sustained longer-term improvements and lower risk of clinically important deterioration (CID).

Methods: Patients were randomized to umeclidinium/vilanterol, umeclidinium, or salmeterol for 24 weeks. The patient-reported outcomes (PROs) Transition Dyspnea Index (TDI), Evaluating Respiratory Symptoms, St George's Respiratory Questionnaire (SGRQ) and COPD Assessment Test (CAT) were assessed.

Clinical predictors of gangrenous appendicitis: elevated total bilirubin level and computed tomography scan findings.

Aim: Patients with gangrenous appendicitis usually require emergency surgery. Preoperative diagnosis of gangrenous appendicitis is clinically important but not always straightforward. We undertook this study to identify preoperative predictors of gangrenous appendicitis.

Prognostic value of clinically important deterioration in COPD: IMPACT trial analysis.

Introduction: Clinically important deterioration (CID) is a multicomponent measure for assessing disease worsening in chronic obstructive pulmonary disease (COPD). This analysis investigated the prognostic value of a CID event on future clinical outcomes and the effect of single-inhaler triple dual therapy on reducing CID risk in patients in the IMPACT trial.

Methods: IMPACT was a phase III, double-blind, 52-week, multicentre trial.

Impact of baseline COPD symptom severity on the benefit from dual mono-bronchodilators: an analysis of the EMAX randomised controlled trial.

Rationale: Symptom relief is a key treatment goal in patients with chronic obstructive pulmonary disease (COPD). However, there are limited data available on the response to bronchodilator therapy in patients at low risk of exacerbations with different levels of symptom severity. This study compared treatment responses in patients with a range of symptom severities as indicated by baseline COPD assessment test (CAT) scores.

Salbutamol use in relation to maintenance bronchodilator efficacy in COPD: a prospective subgroup analysis of the EMAX trial.

Background: Short-acting β-agonist (SABA) bronchodilators help alleviate symptoms in chronic obstructive pulmonary disease (COPD) and may be a useful marker of symptom severity. This analysis investigated whether SABA use impacts treatment differences between maintenance dual- and mono-bronchodilators in patients with COPD.

Methods: The Early MAXimisation of bronchodilation for improving COPD stability (EMAX) trial randomised symptomatic patients with low exacerbation risk not receiving inhaled corticosteroids 1:1:1 to once-daily umeclidinium/vilanterol 62.

Type 2 Diabetes Mellitus Associated with Obesity (Diabesity). The Central Role of Gut Microbiota and Its Translational Applications.

Obesity is a condition of rising prevalence worldwide, with important socioeconomic implications, being considered as a growing public health concern. Frequently, obesity brings other complications in addition to itself-like Type 2 Diabetes Mellitus (T2DM)-sharing origin, risk factors and pathophysiological mechanisms. In this context, some authors have decided to include both conditions as a unique entity known as "diabesity".

Pregnancy Outcomes Following Pediatric Liver Transplantation: A Single-Center Experience in Japan.

BACKGROUND The number of pregnancies after liver transplantation (LT) is increasing; however, the safety and incidence of complications associated with these pregnancies are still unclear. In this report, we retrospectively assessed the influences and problems associated with post-transplant pregnancy on allografts, recipients, and fetuses. MATERIAL AND METHODS A total of 14 pregnancies were identified in 8 female recipients between 2005 and 2018.

Measuring disease activity in COPD: is clinically important deterioration the answer?

Given the heterogeneity of chronic obstructive pulmonary disease (COPD), personalized clinical management is key to optimizing patient outcomes. Important treatment goals include minimizing disease activity and preventing disease progression; however, quantification of these components remains a challenge. Growing evidence suggests that decline over time in forced expiratory volume in 1 s (FEV), traditionally the key marker of disease progression, may not be sufficient to fully determine deterioration across COPD populations.

Early and sustained symptom improvement with umeclidinium/vilanterol monotherapy in COPD: a analysis of the EMAX randomised controlled trial.

Background: In chronic obstructive pulmonary disease (COPD), both the time needed for patients to gain symptom improvement with long-acting bronchodilator therapy and whether an early response is predictive of a sustained response is unknown. This study aimed to investigate how quickly meaningful symptom responses are seen in patients with COPD with bronchodilator therapy and whether these responses are sustained.

Methods: Early MAXimisation of bronchodilation for improving COPD stability (EMAX) was a 24-week, double-blind, double-dummy, parallel-group trial that randomised patients to umeclidinium/vilanterol (UMEC/VI), umeclidinium or salmeterol.

Efficacy of umeclidinium/vilanterol versus umeclidinium and salmeterol monotherapies in symptomatic patients with COPD not receiving inhaled corticosteroids: the EMAX randomised trial.

Background: Prospective evidence is lacking regarding incremental benefits of long-acting dual- versus mono-bronchodilation in improving symptoms and preventing short-term disease worsening/treatment failure in low exacerbation risk patients with chronic obstructive pulmonary disease (COPD) not receiving inhaled corticosteroids.

Methods: The 24-week, double-blind, double-dummy, parallel-group Early MAXimisation of bronchodilation for improving COPD stability (EMAX) trial randomised patients at low exacerbation risk not receiving inhaled corticosteroids, to umeclidinium/vilanterol 62.5/25 μg once-daily, umeclidinium 62.

Long-term cost and utility consequences of short-term clinically important deterioration in patients with chronic obstructive pulmonary disease: results from the TORCH study.

Clinically important deterioration (CID) in chronic obstructive pulmonary disease (COPD) is a novel composite endpoint that assesses disease stability. The association between short-term CID and future economic and quality of life (QoL) outcomes has not been previously assessed. This analysis considers 3-year data from the TOwards a Revolution in COPD Health (TORCH) study, to examine this question.

Efficacy and safety of the dual bronchodilator combination umeclidinium/vilanterol in COPD by age and airflow limitation severity: A pooled post hoc analysis of seven clinical trials.

Background: Elderly patients with chronic obstructive pulmonary disease (COPD) and those with more severe airway limitation are perceived to experience reduced efficacy from inhaled bronchodilators, especially those administered in a dry powder inhaler. This study compared the efficacy and safety of a long-acting muscarinic antagonist/long-acting β-agonist dry powder combination in elderly patients with COPD and patients with moderate-to-very severe airflow limitation.

Methods: This post hoc pooled analysis of seven randomized studies of ≥12 weeks' duration investigated the efficacy and safety of umeclidinium/vilanterol (UMEC/VI) 62.

Impact of prior and concurrent medication on exacerbation risk with long-acting bronchodilators in chronic obstructive pulmonary disease: a post hoc analysis.

Background: Symptomatic patients with chronic obstructive pulmonary disease (COPD) and low exacerbation risk still have disease instability, which can be improved with better bronchodilation. We evaluated two long-acting bronchodilators individually and in combination on reducing exacerbation risk and the potential impact of concurrent medication in these patients.

Methods: Integrated post hoc intent-to-treat (ITT) analysis of data from two large 24-week, randomized placebo (PBO)-controlled trials (NCT01313637, NCT01313650).

Introduction: The cost-effectiveness of long-acting muscarinic antagonist (LAMA) umeclidinium bromide (UMEC) 62.5 μg as add-on therapy to other maintenance COPD treatments is unknown.

Methods: This analysis assessed the cost-effectiveness of the following in COPD: UMEC + fluticasone furoate/vilanterol 100/25 μg (FF/VI); UMEC + fluticasone propionate/salmeterol 250/50 μg (FP/SAL); and UMEC + several alternative choices of inhaled corticosteroid/long-acting β-agonist (ICS/LABA).

Umeclidinium/Vilanterol Versus Tiotropium/Olodaterol in Maintenance-Naïve Patients with Moderate Symptomatic Chronic Obstructive Pulmonary Disease: A Post Hoc Analysis.

Introduction: Appropriate timing for dual bronchodilator therapy initiation in chronic obstructive pulmonary disease (COPD) management is uncertain. Combination therapy is recommended as step-up from monotherapy or first-line treatment in patients with persistent symptoms. In this setting, umeclidinium/vilanterol (UMEC/VI) demonstrated improved lung function and reduced rescue medication use over tiotropium/olodaterol (TIO/OLO).

Cost-effectiveness analysis of umeclidinium bromide/vilanterol 62.5/25 mcg versus tiotropium/olodaterol 5/5 mcg in symptomatic patients with chronic obstructive pulmonary disease: a Spanish National Healthcare System perspective.

Background: A head-to-head study demonstrated the superiority of once-daily umeclidinium bromide/vilanterol (UMEC/VI) 62.5/25 mcg on trough forced expiratory volume in 1 s (FEV) versus once-daily tiotropium/olodaterol (TIO/OLO) 5/5 mcg in symptomatic patients with chronic obstructive pulmonary disease (COPD). This analysis evaluated the cost effectiveness of UMEC/VI versus TIO/OLO from a Spanish National Healthcare System perspective, using data from this study and Spanish literature.

Long-term outcomes following first short-term clinically important deterioration in COPD.

Background: Chronic obstructive pulmonary disease (COPD) is characterized by varying trajectories of decline. Information regarding the prognostic value of preventing short-term clinically important deterioration (CID) in lung function, health status, or first moderate/severe exacerbation as a composite endpoint of worsening is needed. We evaluated post hoc the link between early CID and long-term adverse outcomes.
