BACKGROUND: Radiation pneumonitis (RP) is a frequent complication of concurrent chemoradiotherapy (CCRT) and is associated with severe symptoms that decrease quality of life and might result in pulmonary fibrosis or death. The aim of this study is to identify whether pulmonary function test (PFT) abnormalities may predict RP in non-small cell lung cancer (NSCLC) patients. METHODS: A prospective multi-institutional study was conducted with locally advanced and oligometastatic NSCLC patients...

In the respiratory tract, intracellular cAMP has a key role in the smooth muscle relaxation induced by β2 -adrenoceptors/Gs protein/adenylyl cyclase axis. In other tissues, cAMP also works as an extracellular messenger, after its efflux and interstitial conversion to adenosine by ectoenzymes. The aim of this study was to identify cAMP efflux and "extracellular cAMP-adenosine pathway" in the airway smooth muscle. Firstly, we tested the ability of β2 -adrenoceptor agonists formoterol or fenoterol to increase the extracellular cAMP in isolated tracheal rings from adult male Wistar rats...

INTRODUCTION: The prevalence and the variability of clinical practice in acute bronchiolitis make it a perfect candidate to monitor the proper use of resources. The aim of this study is to analyse the differences in the use of non-recommended resources in the management of bronchiolitis in the Emergency Department, before and after the establishment of a new protocol. METHODS: A retrospective study was conducted on a sample of patients diagnosed with acute bronchiolitis in the Emergency Department of a tertiary hospital, before (December 2014) and after (December 2016) the implementation of a new protocol...

To investigate the effectiveness of nutritional supplement Bao Khi Khang as an adjuvant therapy in acute exacerbations of chronic obstructive pulmonary disease (COPD) compared to conventional therapy alone. This was a prospective, randomized, open-label controlled trial in 60 patients presenting with acute exacerbation of COPD. Patients were randomized into two groups, the control and the experimental groups. The control group was treated with the standard therapeutic protocol (Antimicrobial+Corticosteroids+Bronchodilator+Mucolytic drugs)...

BACKGROUND: The effects of H4 R antagonists in preclinical asthma models support the study of antagonists of the H4 R in the treatment of asthma in humans. JNJ-39758979 is a potent and highly-selective oral H4 R antagonist. OBJECTIVE: We sought to evaluate the safety and efficacy of the H4 R-antagonist JNJ-39758979 in adult patients with uncontrolled asthma. METHODS: One hundred and fifteen eligible patients were randomly assigned to JNJ-39758979 300 mg or placebo once daily for 12 weeks in this phase 2a, double-blind, multicenter, placebo-controlled study...

PURPOSE: Severe asthma and asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) are difficult to control and are often associated with poor clinical outcomes. However, much is not understood regarding the diagnosis and treatment of severe asthma and ACOS. To evaluate the current perceptions of severe asthma and COPD among asthma and COPD specialists, we designed an e-mail and internet-based questionnaire survey. METHODS: Subjects were selected based on clinical specialty from among the members of the Korean Academy of Asthma, Allergy and Clinical Immunology and the Korean Academy of Tuberculosis and Respiratory Diseases...

Background: The beta-2 adrenergic receptor (ADRB2) Arg16Gly polymorphism may alter the bronchodilation response to long-acting beta2-agonists, thereby influencing the clinical effectiveness of LABAs plus corticosteroids (ICS) treatment. But the results of individual studies are inconclusive. Methods: A systematic search was conducted in PubMed, Embase, the Cochrane Database, WHO International Clinical Trials Registry Platform, Chinese National Knowledge Infrastructure, Wanfang, Chinese BioMedical Literature Database, and VIP databases...

REVIEW
V Madhu Chari, Robert Andrew McIvor
Asthma is a chronic disease of airway inflammation with a large global burden. Despite established, guideline-based stepwise therapy, a significant proportion of patients remain symptomatic and poorly controlled. As such, there is a need for additional safe, effective, convenient, and cost-effective therapies that can be broadly applied across a range of asthma phenotypes. Tiotropium is a long-acting muscarinic antagonist (LAMA) that leads to bronchodilation by blocking endogenous acetylcholine receptors in the airways...

Objective: The aim of this study was to evaluate the cost-effectiveness of the long-acting beta-2 agonist (LABA)/long-acting muscarinic antagonist (LAMA) dual bronchodilator indacaterol/glycopyrronium (IND/GLY) as a maintenance treatment for COPD patients from the perspective of health care payer in Taiwan. Patients and methods: We adopted a patient-level simulation model, which included a cohort of COPD patients aged ≥40 years. The intervention used in the study was the treatment using IND/GLY, and comparators were tiotropium or salmeterol/fluticasone combination (SFC)...

H3N2 was first detected in July 2011 in the USA. It is responsible for sporadic cases of influenza and localised outbreaks and has not yet taken over on an epidemic or pandemic scale. An 84-year-old man presented with a dry cough, fever and myalgia for 3 days. On examination, he had a pulse of 98 bpm and blood pressure of 124/88 mm Hg. The patient was tachypnoeic, SpO2 was 90%. Auscultation revealed bilateral diffuse wheeze and crackles. He had generalised muscle tenderness on examination. On admission, creatinine was 1...

Early-life use of antibiotics is associated with asthma. We examined the effect of antibiotic use for early-life bronchiolitis on the development of new-onset asthma in children from Taiwan between 2005 and 2010. Data were from the National Health Insurance Research Database 2010, and diseases were coded using the International Classification of Disease (ICD). We classified the patients, all of whom had bronchiolitis, as having asthma or not having asthma. Asthma was diagnosed using ICD criteria and by use of an inhaled bronchodilator and/or corticosteroid twice in one year...

RATIONALE: Bronchodilation and exercise training (ExT) improve exercise tolerance in patients with chronic obstructive pulmonary disease (COPD); however, behavior modification is required to impact on daily physical activity (PA). OBJECTIVES: To assess whether tiotropium/olodaterol, ±ExT, would improve exercise endurance time (EET) and PA compared with placebo in patients participating in a self-management behavior-modification (SMBM) program. METHODS: A 12-week, randomized, partially double-blind, placebo-controlled, parallel-group trial in patients with COPD (PHYSACTO®; NCT02085161)...

The repurposing of drug delivery by the pulmonary route has been applied to treatment and prophylaxis of an increasingly wide range of respiratory diseases. Repurposing has been most successful for the delivery of inhaled bronchodilators and corticosteroids in patients with asthma and chronic obstructive pulmonary disease (COPD). Repurposing utilizes the advantages that the pulmonary route offers in terms of more targeted delivery to the site of action, the use of smaller doses, and a lower incidence of side-effects...
