BACKGROUND: Chronic obstructive pulmonary disease (COPD) is the third-leading cause of death in the United States. Guideline recommendations for medication therapy include the use of inhaled medications for management of stable COPD. There are limited data available describing prescribing percentages of medications in patients with COPD. AIM: To determine the prescribing percentages of medications for COPD in a national, cross-sectional study. METHODS: This was a national, cross-sectional study using data from the National Ambulatory Medical Care Survey (NAMCS) in 2013...

Gastroesophageal reflux disease (GERD) and Barrett's Esophagus (BE), which are prevalent in the World Trade Center (WTC) exposed and general populations, negatively impact quality of life and cost of healthcare. GERD, a risk factor of BE, is linked to obstructive airways disease (OAD). We aim to identify serum biomarkers of GERD/BE, and assess the respiratory and clinical phenotype of a longitudinal cohort of never-smoking, male, WTC-exposed rescue workers presenting with pulmonary symptoms. Biomarkers collected soon after WTC-exposure were evaluated in optimized predictive models of GERD/BE...

Because of the serious side effects of the currently used bronchodilators, new compounds with similar functions must be developed. We screened several herbs and found that Polygonum aviculare L. contains ingredients that inhibit the precontraction of mouse and human airway smooth muscle (ASM). High K+ -induced precontraction in ASM was completely inhibited by nifedipine, a selective blocker of L-type voltage-dependent Ca2+ channels (LVDCCs). However, nifedipine only partially reduced the precontraction induced by acetylcholine chloride (ACH)...

The most common therapies for asthma and other chronic lung diseases are anti-inflammatory agents and bronchodilators. While these drugs oppose disease symptoms, they do not reverse established structural changes in the airways and their therapeutic efficacy is reduced with increasing disease severity. The peptide hormone, relaxin, is a Relaxin Family Peptide Receptor 1 (RXFP1) receptor agonist with unique combined effects in the lung that differentiates it from these existing therapies. Relaxin has previously been reported to have cardioprotective effects in acute heart failure as well anti-fibrotic actions in several organs...

Little is known about the prognosis of adults with new-onset asthma. Cross-sectional studies suggest that these patients may exhibit accelerated decline in forced expiratory volume in 1 s (FEV 1 ). However, risk factors for accelerated decline in lung function have not yet been identified.We aimed to identify these risk factors in a prospective 5-year follow-up study in 200 adults with newly diagnosed asthma. In the current study, clinical, functional and inflammatory parameters were assessed annually for 5 years...

OBJECTIVE: The "united airway disease" concept is based on the bidirectional interaction between asthma and rhinitis. The aim of this study was to determine the relationship between upper airway diseases and bronchial hyperresponsiveness (BHR), as well as their association with the fractional concentration of exhaled nitric oxide (FeNO) and atopy in patients with persistent symptoms suggestive of asthma requiring methacholine challenge testing (MCT) to confirm asthma diagnosis. METHODS: A cross-sectional prospective study was carried out in adult patients with persistent asthma-like symptoms and negative bronchodilator testing...

BACKGROUND: Evidence is scarce on the relative risk-benefit of inhaled triple therapy, consisting of inhaled corticosteroid, long-acting muscarinic antagonist, and long-acting β2 -agonist, versus dual bronchodilation for chronic obstructive pulmonary disease (COPD). We aimed to compare a single-inhaler triple combination of beclometasone dipropionate, formoterol fumarate, and glycopyrronium (BDP/FF/G) versus a single-inhaler dual bronchodilator combination of indacaterol plus glycopyrronium (IND/GLY) in terms of the rate of moderate-to-severe COPD exacerbations over 52 weeks of treatment...

AIMS: Thrombin is a serine proteinase that is not only involved in coagulation cascade, but also mediates a number of biological responses relevant to tissues repair, and induces bronchoconstriction. TGF-β plays a pivotal role in airway remodeling due to its effects on airway smooth muscle proliferation and extracellular matrix (ECM) deposition. Recently, bronchoconstriction itself is found to constitute a form of strain and is highly relevant to asthmatic airway remodeling. However, the underlying mechanisms remain unknown...

Asthma management is in an intriguing phase, with acceptance of asthma as a heterogeneous condition with different phenotypes and underlying mechanisms and the potential for personalized asthma care, in parallel with increasing evidence about the population-level impact of basic strategies to increase access to medicines and improve inhaler technique and adherence. These changes have been facilitated by a more comprehensive view of evidence, including both randomized controlled trials with high internal validity and pragmatic and observational studies with high generalizability to patients in clinical practice...

OBJECTIVE: There is controversy about the diagnostic criteria, prevalence, symptoms, and spirometry characteristics of asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO). Recent data indicate that the fixed method for diagnosing airway obstruction (AO) may overestimate ACO prevalence in the elderly, and a variable method may be more accurate. We aimed at estimating ACO prevalence in a general population sample and comparing patient and clinical features in subjects with ACO, COPD, and asthma...

Long-acting bronchodilators and inhaled corticosteroids (ICS) are the cornerstones in treatment of chronic obstructive and inflammatory pulmonary diseases. However, non-adherence to guidelines is widespread. Detailed information on real-life treatment patterns is needed to promote rational use. We aimed to investigate nationwide time trends in individual-level treatment patterns of long-acting bronchodilators and ICS. Using nationwide Danish health registries, we identified all Danish adults with a prescription for long-acting bronchodilators and/or ICS from 2000-2016...

The mechanisms whereby anti-cholinergics improve asthma outcomes, such as lung function, symptoms and rate of exacerbation, can be numerous. The most obvious is by affecting the contraction of airway smooth muscle (ASM). The acetylcholine released from the cholinergic nerves is the most important bronchoconstrictor that sets the baseline degree of contractile activation of ASM in healthy individuals. Although the degree of ASM's contractile activation can also be fine-tuned by a plethora of other bronchoconstrictors and bronchodilators in asthma, blocking the ceaseless effect of acetylcholine on ASM by anti-cholinergics reduces, at any given moment, the overall degree of contractile activation...

BACKGROUND: Omalizumab, a humanized anti-IgE monoclonal antibody, is the first molecularly targeted drug for severe asthmatics. However, responses to omalizumab vary widely among patients. OBJECTIVES: This study aimed to assess the potential of baseline serum cytokine levels as predictors of responsiveness to omalizumab. METHODS: Thirty-one patients with severe, persistent asthma were enrolled in this study and administered omalizumab for at least 1 year...

BACKGROUND: Asthma is a heterogeneous and complex disease in both its clinical course and response to treatment. IL-13 is central to Type 2 inflammation and contributes to many features of asthma. In a previous Phase 2 study, lebrikizumab, an anti-IL-13 monoclonal antibody, did not significantly improve FEV 1 in mild-to-moderate asthma patients not receiving ICS therapy. This Phase 3 study was designed to further assess the efficacy and safety of lebrikizumab in adult patients with mild-to-moderate asthma treated with daily short-acting β 2 -agonist therapy alone...

INTRODUCTION: Cough exceeding 3-8 weeks was defined as chronic cough in various guides. Asthma is the most common cause of chronic-specific cough. Causes other than asthma include prolonged bacterial bronchitis and upper airway cough syndrome (UACS). Nitric oxide (NO) causes vascular smooth muscle relaxation, bronchodilation, and oxidant effects via its metabolite, peroxynitrite. An increase in NO results in inflammation, vasodilatation, and bronchial edema. MATERIALS AND METHODS: The study group included 90 patients aged 6-17 years selected from individuals presenting to the Pediatric Immunology and Allergic Diseases Clinic with cough persisting for 4 weeks and 30 other patients representing to the control group...

BACKGROUND: Asthmatic cough is often refractory to standard treatments such as inhaled corticosteroids and long-acting β2 agonists (ICS/LABA). Tiotropium may modulate cough reflex sensitivity of acute viral cough, but its efficacy in asthmatic cough remains unknown. OBJECTIVE: To evaluate whether tiotropium improves cough and cough reflex sensitivity in asthmatic patients refractory to ICS/LABA. METHODS: Seventeen consecutive asthmatic patients with chronic cough despite the use of ICS/LABA [13 females; 43...
