The Société de Pneumologie de Langue Française proposes a decision algorithm on long-term pharmacological COPD treatment. A working group reviewed the literature published between January 2009 and May 2016. This document lays out proposals and not guidelines. It only focuses on pharmacological treatments except vaccinations, smoking cessation treatments and oxygen therapy. Any COPD diagnosis, based on pulmonary function tests, should lead to recommend smoking cessation, vaccinations, physical activity, pulmonary rehabilitation in case of activity limitation, and short-acting bronchodilators...

Current asthma treatments are effective for the majority of patients with mild-to-moderate disease. However, in those with more severe refractory asthma, agents other than inhaled corticosteroids and beta-agonists are needed both to better manage this group of patients and to avoid the side effects of high-dose corticosteroids and the social and personal hardship endured. Several biological pathways have been targeted over the last 20 years, and this research has resulted in pharmacological approaches to attempt to better treat patients with severe refractory asthma...

Chronic obstructive pulmonary disease (COPD) is caused by α1-antitrypsin deficiency (AATD) genetic susceptibility and exacerbated by infection. The current pilot study aimed at studying the combined effect of AATD and bacterial loads on the efficacy of COPD conventional pharmacotherapy. Fifty-nine subjects (29 controls and 30 COPD patients) were tested for genetic AATD and respiratory function. The bacterial loads were determined to the patients' group who were then given a long acting beta-agonist and corticosteroid inhaler for 6 months...

BACKGROUND: Management of chronic obstructive pulmonary disease (COPD) commonly involves long-acting bronchodilators including beta-agonists (LABA) and muscarinic antagonists (LAMA). In individuals with persistent symptoms or frequent exacerbations, inhaled corticosteroids (ICS) are also used. LABA and LAMA bronchodilators are now available in single combination inhalers. However, the benefits and risks of adding ICS to combination LABA/LAMA inhalers remains unclear. OBJECTIVES: To assess the effect of adding an inhaled corticosteroid (ICS) to combination long-acting beta₂-agonist (LABA)/long-acting muscarinic antagonist (LAMA) inhalers for the treatment of stable COPD...

PURPOSE: Guidelines need to be tailored to where they are applied. We aimed to describe the distinctive asthma severity profile and the pattern of controller prescription in Korean children. METHODS: Twelve pediatric allergists from tertiary medical centers reviewed medical records of all asthmatic children who visited their clinics between September 1 and November 30 of 2013. Controller prescriptions were re-classified into 4 categories, then the prevalence of each asthma severity category and the controller prescription patterns according to asthma severity assessed by a Western (Global Initiative for Asthma, GINA) and an Asia-Pacific (Japanese Pediatric GuideLine, JPGL) guideline were evaluated...

As one of the candidates of the therapeutic strategy for asthma in addition to inhaled corticosteroids (ICS), leukotriene receptor antagonists (LTRAs) are known to be useful for long-term management of asthma patients complicated by allergic rhinitis (AR) or exercise-induced asthma (EIA). Currently available LTRAs are pranlukast hydrate, zafirlukast, and montelukast. These LTRAs have a bronchodilator action and inhibit airway inflammation, resulting in a significant improvement of asthma symptoms, respiratory function, inhalation frequency of as-needed inhaled β2-agonist, airway inflammation, airway hyperresponsiveness, dosage of ICSs, asthma exacerbations, and patients' QOL...

BACKGROUND: Inhaled corticosteroid (ICS) with long-acting beta-2 agonists is a well-documented combination therapy for chronic obstructive pulmonary disease (COPD) based on its additive anti-inflammatory properties. By contrast, the recommendation of ICS in combination with long-acting muscarinic antagonist (LAMA) is not evidence-based. In this study, neutrophils obtained from COPD patients were used to compare the anti-inflammatory effects of aclidinium bromide (a long-acting muscarinic antagonist) with corticosteroids and their potential additive effect...

Respiratory symptoms at rest or during exercise may restrain the physical capabilities required for normal motor and psychosocial development in children. The most frequent cause of exercise intolerance, apart from poor physical fitness, is exercise-induced bronchoconstriction (EIB), which may occur in some healthy children and in children with asthma. It is proposed that hyperventilation during exercise is associated with drying and cooling of airways, which can trigger a proinflammatory response. Several tests are used to confirm EIB, and the exercise-challenge test is the most common...

Clinical guidelines recommend long-acting bronchodilators as first maintenance therapy for chronic obstructive pulmonary disease (COPD), with inhaled corticosteroids (ICS) reserved for patients with more severe disease and exacerbations. The aim of this analysis was to examine real-life prescribing of first maintenance therapy for COPD in the UK. Data were extracted from the UK Optimum Patient Care Research Database for patients with a first prescription for COPD maintenance therapy between 2009 and 2012 and a diagnosis of COPD at or before the date of the first prescription for COPD maintenance therapy...

BACKGROUND: Beta-2 adrenergic receptors (β2ARs) are located throughout the body including airway and alveolar cells. The β2ARs regulate lung fluid clearance through a variety of mechanisms including ion transport on alveolar cells and relaxation of the pulmonary lymphatics. We examined the effect of an inhaled β2-agonist (albuterol) on alveolar-capillary membrane conductance (DM) and pulmonary capillary blood volume (VC) in healthy humans. METHODS: We assessed the diffusing capacity of the lungs for carbon monoxide (DLCO) and nitric oxide (DLNO) at baseline, 30 minutes, and 60 minutes following nebulized albuterol (2...

OBJECTIVES: Long-acting bronchodilators are mainstay treatment for moderate to severe chronic obstructive pulmonary disease. A growing body of evidence indicates an increased risk of cardiovascular events upon initiation of these medications. We hypothesize that this risk is higher in patients with chronic obstructive pulmonary disease who had a preexisting cardiovascular disease regardless of receipt of any cardiovascular medication. METHODS: A retrospective cohort of patients with a diagnosis of chronic obstructive pulmonary disease based on two outpatient visits or one inpatient visit for chronic obstructive pulmonary disease (International Classification of Diseases, 9th Edition, Clinical Modification codes 491...

BACKGROUND: We hypothesized that an injured lung graft from donation after cardiac death donors could be reconditioned before transplantation using an ex vivo lung perfusion (EVLP) system and ventilation with high-dose short-acting β2-adrenergic receptor agonists. METHODS: Cardiac arrest was induced in a canine model by intravenous potassium chloride injection. Lungs were randomly assigned to two groups after 150 minutes of warm ischemia: inhalation of 1,400 μg of procaterol (BETA group, n = 5) or control group receiving solvent (CON group, n = 5) during EVLP...

Introduction While pediatric asthma continues to be a highly studied disease, data to suggest clear strategies to decrease asthma related revisits or readmissions is lacking. The purpose of our study was to assess the effect of emergency department (ED) direct dispensing of beta-agonist metered dose inhalers on pediatric asthma ED revisit and readmission rates. Methods We conducted a retrospective cohort study of pediatric patients discharged from the pediatric ED with a diagnosis of asthma. Our primary outcome measured the rate of asthma revisits to the ED or admissions to the hospital within 28 days...

BACKGROUND: Maintaining high treatment adherence levels is critical for effective management of chronic diseases. The Adherence Starts with Knowledge 20 (ASK-20) questionnaire is the only linguistically validated patient-reported treatment adherence tool available in Japan. We conducted additional analyses on ASK-20 data from Japanese adults with asthma. METHODS: This was a prospective, non-interventional, single-visit, multi-centre study in Japanese adults (n = 300) with asthma receiving long-term treatment with inhaled corticosteroids (ICS) or ICS/long-acting beta-agonists...

Asthma is a chronic inflammatory airway disease, and its treatment is frequently challenging despite detailed national and international guidelines. While basic anti-inflammatory therapy usually consists of inhaled corticosteroids in doses adapted to the asthma severity, add-on treatment with bronchodilators is essential in more severe asthma. Only recently, the long-acting anticholinergic tiotropium was introduced into the GINA guidelines. This review reports on the studies that have been performed with tiotropium in adult asthmatic patients...

A case study of 35-year-old woman with persistent breathlessness and wheezing that had been unsuccessfully treated with inhaled beta 2-agonists and steroids for about two years. Patient developed dry cough and haemoptysis, so investigated further. Spirometry demonstrated a restrictive pattern. Chest CT demonstrated well defined hyperdense lesion in right middle lobe. Biopsy taken from the mass during bronchoscopy demonstrated the picture of atypical bronchial carcinoid. In this case, due to the lack of awareness, diagnosis of carcinoid was delayed by two years...

International guidelines provide conflicting recommendations on how to use bronchodilators to manage childhood acute wheezing conditions in the emergency department (ED), and there is variation within and among countries in how these conditions are managed. This may be reflective of uncertainty about the evidence. This overview of systematic reviews (SRs) aimed to synthesize, appraise, and present all SR evidence on the efficacy and safety of inhaled short-acting bronchodilators to treat asthma and wheeze exacerbations in children 0-18 years presenting to the ED...
