Peripheral airway inflammation and dysfunction are key elements in the pathogenesis of COPD. The exhaled alveolar fraction of nitric oxide (CANO) is an indirect biomarker of lung peripheral inflammation. We tested whether inhaled long-acting bronchodilators (LABA) can affect CANO and we evaluated correlations with lung mechanics in patients with COPD. Two-centre, randomised, double blind, crossover study including COPD patients with moderate-to-severe airflow obstruction. Following a pharmacological washout, multi-flow exhaled fraction of NO (FENO), plethysmography, lung diffusion (DLCO), single breath nitrogen washout test and dyspnoea were measured in a crossover manner at baseline and 30, 60 and 180 minutes following administration of salmeterol (Sal) or formoterol fumarate (FF)...

Objective Out-of-pocket costs strongly affect patient adherence with medicines. For asthma, guidelines recommend that most patients should be prescribed regular low-dose inhaled corticosteroids (ICS) alone, but in Australia most are prescribed combination ICS-long-acting β2-agonists (LABA), which cost more to patients and government. The present qualitative study among general practitioners (GPs) explored the acceptability, and likely effect on prescribing, of lower patient copayments for ICS alone. Methods Semistructured telephone interviews were conducted with 15 GPs from the greater Sydney area; the interviews were transcribed and thematically analysed...

Epithelial human blood group antigens (HBGAs) on O-glycans play roles in pathogen binding and the initiation of infection, while similar structures on secretory mucins exert protective functions. These double-faced features of O-glycans in infection and innate immunity are reviewed based on two instructive examples of bacterial and viral pathogens. Helicobacter pylori represents a class 1 carcinogen in the human stomach. By expressing blood group antigen-binding adhesin ( BabA ) and LabA adhesins that bind to Lewis-b and LacdiNAc, respectively, H...

Triple inhaled corticosteroid (ICS)/long-acting muscarinic antagonist (LAMA)/long-acting β2 -agonist (LABA) therapy is recommended for symptomatic patients with chronic obstructive pulmonary disease (COPD) and at risk of exacerbations. However, the benefits versus side-effects of triple inhaled therapy for COPD, based on distinct patient clinical profiles, are unclear. FULFIL, a phase III, randomised, double-blind study, compared 24 weeks of once-daily fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) 100/62...

BACKGROUND: Asthmatics that are exposed to inhaled pollutants such as cigarette smoke (CS) have increased symptom severity. Approximately 25% of adult asthmatics are thought to be active smokers and many sufferers, especially in the third world, are exposed to high levels of inhaled pollutants. The mechanism by which CS or other airborne pollutants alter the disease phenotype and the effectiveness of treatment in asthma is not known. The aim of this study was to determine the impact of CS exposure on the phenotype and treatment sensitivity of rodent models of allergic asthma...

Aptamers are oligonucleotide receptors obtained through an iterative selection process from random-sequence libraries. While many aptamers for a broad range of targets with high affinity and selectivity have been generated, a lack of high-resolution structural data and the limitations of currently available biophysical tools greatly impede understanding of the mechanisms of aptamer-ligand interactions. Here we demonstrate that an approach based on native electrospray ionization mass spectrometry (ESI-MS) can be successfully applied to characterize aptamer-ligand complexes in all details...

Bronchodilators are essential for the perioperative management of patients with chronic obstructive pulmonary disease (COPD) undergoing surgery for lung cancer. The objective of the present study was to examine whether the usage of a long-acting β2-agonist (LABA) with a long-acting muscarinic antagonist (LAMA) could optimize preoperative lung function and reduce the risk for postoperative pulmonary complications. Thirty-two consecutive patients with moderate-to-severe COPD who underwent a lobectomy for lung cancer and received preoperative LAMA (n=19) or LAMA/LABA (n=13) therapy between January 2005 and December 2015 were enrolled in this retrospective study...

Introduction Long-acting β2 -adrenoceptor (β2 -AR) agonists (LABAs) plus long-acting muscarinic antagonists (LAMAs) is the cornerstone for treating chronic obstructive pulmonary disease (COPD). LABA/LAMA combinations elicit clinical and functional synergistic interaction, and such an interaction should permit to reduce the dose of each monocomponent in the drug mixture to minimize the risk of adverse events (AEs). Overall, currently available LABA/LAMA fixed-dose combinations (FDCs) combine the drugs at the same doses of formulations designed for a single drug...

Background: To date, few studies have focused on the clinical and allergic characteristics of asthma in the elderly, defined as asthma in people aged 60 or over. Thus, we propose to identify and study the clinical and allergic characteristics and comorbidities of patients with asthma among the elderly. Methods: A retrospective, observational, descriptive study was developed in five clinics and hospitals in Argentina. Allergy Physicians analyzed their patients' medical records in 2014 and included those adults over the age of 60, who had been diagnosed with asthma according to the GINA guidelines...

Purpose: COPD is a progressive disease characterized by exacerbations and a decline in health status and lung function. Clinically important deterioration (CID) is a composite endpoint used to evaluate treatment efficacy. This analysis evaluated the impact of a direct switch to once-daily indacaterol/glycopyrronium 110/50 µg (IND/GLY) from previous monotherapy with a long-acting β2 -agonist (LABA) or long-acting muscarinic antagonist (LAMA) or with an LABA and an inhaled corticosteroid (LABA + ICS) on reducing CID...

We present the case of a 77-year-old man diagnosed with chronic obstructive pulmonary disease (COPD) stage D with emphysema phenotype and treated with triple therapy (salmeterol, fluticasone propionate, and tiotropium) for 1 year without relevant improvements in exertional dyspnea and disease impact. After switching to combination therapy with a long-acting β2-agonist (LABA) and a long-acting muscarinic antagonist (LAMA) (indacaterol/glycopyrronium), we observed, in a 3-month period, a substantial reduction of the modified Medical Research Council (mMRC) dyspnea scale and COPD Assessment Test (CAT) scores...

Kallikrein-related peptidase 12 (KLK12) is a kallikrein family peptidase involved in angiogenesis - a complex biological process in which the sprouting, migration and stabilization of endothelial cells requires extracellular matrix remodeling. To characterize the molecular mechanisms associated with KLK12's proangiogenic activity, we evaluated its ability to hydrolyze various matrix proteins. Our results show that KLK12 efficiently cleaved the human extracellular matrix proteins fibronectin and tenascin, both of which are involved in the regulation of endothelial cell adhesion and migration...
