OBJECTIVE: Chronic airflow limitation (CAL) can develop in a subgroup of patients with asthma. Characterising these patients is important because reduced lung function is a risk factor for adverse asthma outcomes. We hypothesised that heterogeneity in patients with CAL may be influenced by age at asthma onset. We first compared never-smoking asthma patients with and without CAL, and subsequently examined the differences between patients with late and early-onset asthma within the CAL cohort...

PURPOSE: Chronic obstructive pulmonary disease (COPD) is a multi-factorial disorder caused by environmental determinants and genetic risk factors. Understanding the genetic predisposition of COPD is essential to develop personalized treatment regimens. Beta2-adrenergic receptor (ADRB2) gene polymorphisms have been implicated in the pathogenesis of obstructive pulmonary diseases. This study was conducted to assess the genetic association between Arg16Gly and Gln27Glu polymorphisms and COPD in the Egyptian patients, and to analyze their impact on the clinical outcome and therapeutic response...

Patients with cardiovascular disease (CVD) often have multiple comorbid conditions that may interact with each other, confound the choice of treatments, and reduce mortality. Chronic obstructive pulmonary disease (COPD) is one of the most important comorbidities of CVD, which causes serious consequences in patients with ischemic heart disease, stroke, arrhythmia, and heart failure. COPD shares common risk factors such as tobacco smoking and aging with CVD, is associated with less physical activity, and produces systemic inflammation and oxidative stress...

REVIEW
Mandy L Cha, Lais R R Costa
This article discusses the benefits and limitations of inhalation therapy in horses. Inhalation drug therapy delivers the drug directly to the airways, thereby achieving maximal drug concentrations at the target site. Inhalation therapy has the additional advantage of decreasing systemic side effects. Inhalation therapy in horses is delivered by the use of nebulizers or pressured metered dose inhalers. It also requires the use of a muzzle or nasal mask in horses. Drugs most commonly delivered through inhalation drug therapy in horses include bronchodilators, antiinflammatories, and antimicrobials...

Mathilde Leclere
Immune suppressive therapies target exaggerated and deleterious responses of the immune system. Triggered by exogenous or endogenous factors, these improper responses can lead to immune or inflammatory manifestations, such as urticaria, equine asthma, or autoimmune and immune-mediated diseases. Glucocorticoids are the most commonly used immune suppressive drugs and the only ones supported by robust evidence of clinical efficacy in equine medicine. In some conditions, combining glucocorticoids with other pharmacologic and nonpharmacologic treatments, such as azathioprine, antihistamine, bronchodilators, environmental management, or desensitization, can help to decrease dosages and associated side effects...

Safety-data for lumacaftor/ivacaftor (LUM/IVA) combination therapy in patients with severe lung disease (percent predicted forced expiratory volume in 1s [ppFEV1] <40) remain limited. We report immediate post-dose respiratory-related adverse events in 12 patients with severe cystic fibrosis (CF) lung disease (median [IQR] ppFEV1: 34 [31-36]) prescribed LUM/IVA. All patients experienced a decline in ppFEV1 from baseline at 2-hours (median [IQR] relative change: -19 [-21 to -11]%, p<0.001) that persisted at 24-hours but recovered in most patients at 1-month...

REVIEW
Alan Kaplan, Mike Thomas
Chronic obstructive pulmonary disease (COPD) is a common disease leading to further morbidity and significant mortality. The first step for any condition is to make the appropriate diagnosis, and spirometry barriers abound in practice around the world. It is tempting to undertake mass screening on all smokers to detect COPD. While this would pick up cases of COPD, results of studies of its effect on COPD end-points such as exacerbations, hospitalisations and mortality are disappointing. As such, aggressive case finding of COPD by screening for symptoms that patients may not themselves perceive is very important in primary care, with subsequent spirometry defining the diagnosis...

BACKGROUND: Equine asthma is a disease characterised by reversible airflow obstruction, bronchial hyperresponsiveness and airway inflammation following exposure of susceptible horses to specific airborne agents. Although clinical remission can be achieved in a low-airborne dust environment, repeated exacerbations may lead to irreversible airway remodelling. The available data on the pharmacotherapy of equine asthma results from several small studies, and no head-to-head clinical trials have been conducted among the available medications...

PURPOSE OF REVIEW: This review summarizes the current evidence for the management of children with recent upper respiratory tract infections (URTIs). Furthermore, the review includes management guidelines for children with URTIs. RECENT FINDINGS: Good history and clinical examination is sufficient in most children presenting with URTI. Testing for immune markers or preoperative nitric oxide measurement does not add any additional value. Preoperative bronchodilator administration, intravenous induction with propofol, and noninvasive airway management all reduce the occurrence of respiratory adverse events...

Magnesium sulphate is a potential treatment for acute severe asthma. However, the mechanisms and dose-response relationships are poorly understood. The first objective of this study was to examine whether inhaled magnesium sulphate exerts bronchodilator activity measured as bronchoprotection against histamine-induced bronchoconstriction in conscious guinea-pigs alone and combined with salbutamol. Secondly, we examined whether inhaled magnesium sulphate inhibits airways inflammation and function in models of neutrophilic and eosinophilic lung inflammation induced, respectively, by inhaled lipopolysaccharide or the inhaled antigen, ovalbumin (OVA)...

REVIEW
Kristin L Hines, R Stokes Peebles
PURPOSE OF REVIEW: Examine the definition of the asthma-COPD overlap syndrome (ACOS) and current treatment strategies. RECENT FINDINGS: Patients with the ACOS have a lower quality of life and suffer from more complications than those affected by either disease alone. Diagnosis of ACOS is difficult because of the clinical similarities between the two diseases and the various phenotypes that comprise the syndrome. Defining treatment strategies for ACOS has been challenging because many clinical trials for asthma therapy have purposefully excluded patients with features of COPD, and COPD clinical trials have not included patients who might have an asthmatic component to their disease...

INTRODUCTION: Patients with COPD who remain symptomatic on long-acting bronchodilator monotherapy may benefit from step-up therapy to a long-acting bronchodilator combination. This study evaluated the efficacy and safety of umeclidinium (UMEC)/vilanterol (VI) in patients with moderate COPD who remained symptomatic on tiotropium (TIO). METHODS: In this randomized, blinded, double-dummy, parallel-group study (NCT01899742), patients (N=494) who were prescribed TIO for ≥3 months at screening (forced expiratory volume in 1 s [FEV1]: 50%-70% of predicted; modified Medical Research Council [mMRC] score ≥1) and completed a 4-week run-in with TIO were randomized to UMEC/VI 62...

Peganum harmala L. is a medicinal plant from the Mediterranean region and Asia currently used for recreative psychoactive purposes (Ayahuasca analogue), and increasingly involved in toxic cases. Its psychopharmacological and toxicological properties are attributed to quinazoline and β-carboline alkaloids. In this work three major quinazoline alkaloids were isolated from P. harmala extracts and characterized as peganine (vasicine), deoxypeganine (deoxyvasicine) and a novel compound identified by HPLC-DAD-MS and NMR as peganine β-d-glucopyranosyl-(1 → 6)-β-d-glucopyranoside (peganine glycoside)...
