Inhaled corticosteroid/long-acting β-agonist combination therapy is a recommended treatment option for patients with chronic obstructive pulmonary disease (COPD) and increased exacerbation risk, particularly those with elevated blood eosinophil levels. SOPHOS (NCT02727660) evaluated the efficacy and safety of two doses of budesonide/formoterol fumarate dihydrate metered dose inhaler (BFF MDI) formoterol fumarate dihydrate (FF) MDI, each delivered using co-suspension delivery technology, in patients with moderate-to-very severe COPD and a history of exacerbations. In this phase 3, randomised, double-blind, parallel-group, 12-52-week, variable length study, patients received twice-daily BFF MDI 320/10 µg or 160/10 µg, or FF MDI 10 µg.

Exacerbations of chronic obstructive pulmonary disease (COPD) represent a significant clinical problem, and are associated with decreased lung function, worsening quality of life and decreased physical activity levels, with even a single exacerbation having detrimental effects. The occurrence of COPD exacerbations can also have a considerable impact on healthcare costs and mortality rates, with over one-fifth of patients hospitalized for a COPD exacerbation for the first time dying within one year of discharge. This highlights the need for COPD exacerbations to be a major focus in clinical practice.

Considerations for the Correct Diagnosis of COPD and Its Management With Bronchodilators.

Chest

August 2018

Pneumology Department, Hospital Universitario Vall d'Hebron, CIBER de Enfermedades Respiratorias (CIBERES), Barcelona, Spain.

COPD is often misdiagnosed and inappropriately treated in many patients. COPD is a distinct disease from adult-onset asthma; however, some patients with COPD may present with several forms of airway disease described as asthma-COPD overlap (ACO). Bronchodilators and inhaled corticosteroids (ICS) both have a place in standard maintenance treatment of COPD and asthma; however, recommendations for use differ widely.

This Executive Summary of the Global Strategy for the Diagnosis, Management, and Prevention of COPD (GOLD) 2017 Report focuses primarily on the revised and novel parts of the document. The most significant changes include: 1) the assessment of COPD has been refined to separate the spirometric assessment from symptom evaluation. ABCD groups are now proposed to be derived exclusively from patient symptoms and their history of exacerbations; 2) for each of the groups A to D, escalation strategies for pharmacological treatments are proposed; 3) the concept of de-escalation of therapy is introduced in the treatment assessment scheme; 4) nonpharmacologic therapies are comprehensively presented and; 5) the importance of comorbid conditions in managing COPD is reviewed.

Sustained activation of the Renin-Angiotensin-Aldosterone System (RAAS) contributes to the pathogenesis of heart failure. Aldosterone (Aldo) is known to induce both myocardial hypertrophy and fibrosis through oxidative stress and proinflammatory pathways. Here we have investigated whether Aldo-mediated cardiomycocyte hypertrophy is dependent on TRAF3IP2, an upstream regulator of IKK and JNK.

Background: Strict definition of invasive aspergillosis (IA) cases is required to allow precise conclusions about the efficacy of antifungal therapy. The Global Comparative Aspergillus Study (GCAS) compared voriconazole to amphotericin B (AmB) deoxycholate for the primary therapy of IA. Because predefined definitions used for this trial were substantially different from the consensus definitions proposed by the European Organization for Research and Treatment of Cancer/Mycoses Study Group in 2008, we recategorized the 379 episodes of the GCAS according to the later definitions.

Background: Combination long-acting bronchodilator treatment might be more effective than long-acting bronchodilator monotherapy for the treatment of chronic obstructive pulmonary disease (COPD). We aimed to compare the efficacy and safety of umeclidinium (UMEC) plus vilanterol (VI) with tiotropium (TIO) monotherapy, UMEC monotherapy, or VI monotherapy in patients with moderate to very severe COPD.

Methods: In two multicentre, randomised, blinded, double-dummy, parallel-group, active-controlled trials, eligible patients (current or former smokers aged 40 years or older with an established clinical history of COPD) were randomly assigned in 1:1:1:1 ratio to UMEC 125 μg plus VI 25 μg, UMEC 62·5 μg plus VI 25 μg, TIO 18 μg, and either VI 25 μg (study 1) or UMEC 125 μg (study 2).

Research Service, Southeast Louisiana Veterans Health Care System, New Orleans, LA 70161, USA; Heart and Vascular Institute, Tulane University School of Medicine, New Orleans, LA 70112, USA. Electronic address:

Oxidized low-density lipoprotein (oxLDL) induces endothelial cell death through the activation of NF-κB and AP-1 pathways. TRAF3IP2 is a redox-sensitive cytoplasmic adapter protein and an upstream regulator of IKK/NF-κB and JNK/AP-1. Here we show that oxLDL-induced death in human primary coronary artery endothelial cells (ECs) was markedly attenuated by the knockdown of TRAF3IP2 or the lectin-like oxLDL receptor 1 (LOX-1).

Docosahexaenoic acid reverses angiotensin II-induced RECK suppression and cardiac fibroblast migration.

Cell Signal

May 2014

Research Service, Southeast Louisiana Veterans Health Care System, New Orleans, LA 70161, United States; Heart and Vascular Institute, Tulane University School of Medicine, New Orleans, LA 70112, United States. Electronic address:

The omega-3 polyunsaturated fatty acids (ω-3 fatty acids) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been reported to inhibit or delay the progression of cardiovascular diseases, including myocardial fibrosis. Recently we reported that angiotensin II (Ang II) promotes cardiac fibroblast (CF) migration by suppressing the MMP regulator reversion-inducing-cysteine-rich protein with Kazal motifs (RECK), through a mechanism dependent on AT1, ERK, and Sp1. Here we investigated the role of miR-21 in Ang II-mediated RECK suppression, and determined whether the ω-3 fatty acids reverse these effects.
