BACKGROUND: Fetal stress has been proposed to be associated with diseases in both children and adults. Epidemiological studies suggest that maternal exposure to nitrogen dioxide (NO2) contributes to increased morbidity and mortality of offspring with allergic asthma later in life. OBJECTIVES: We aimed to test whether maternal NO2 exposure causes allergic asthma-related consequences in offspring absent any subsequent lung provocation and whether this exposure enhances the likelihood of developing allergic asthma or the intensity of developed allergic airway disease following postnatal allergic sensitization and challenge...

BACKGROUND: This review is the first update of a previously published review in The Cochrane Library (Issue 7, 2015). Interleukin-5 (IL-5) is the main cytokine involved in the activation of eosinophils, which cause airway inflammation and are a classic feature of asthma. Monoclonal antibodies targeting IL-5 or its receptor (IL-5R) have been developed, with recent studies suggesting that they reduce asthma exacerbations, improve health-related quality of life (HRQoL) and lung function...

As part of its single technology appraisal (STA) process, the National Institute for Health and Care Excellence (NICE) invited the company (GlaxoSmithKline) that manufactures mepolizumab (Nucala(®)) to submit evidence on the clinical and cost effectiveness of mepolizumab for the treatment of severe eosinophilic asthma. The School of Health and Related Research Technology Appraisal Group (ScHARR-TAG) at the University of Sheffield was commissioned to act as the independent evidence review group (ERG). The ERG produced a review of the evidence for the clinical and cost effectiveness of mepolizumab as add-on to standard of care (SoC) compared with SoC and omalizumab, based upon the company's submission to NICE...

BACKGROUND: Many patients with chronic illnesses suffer from depression. A poorly controlled asthma that presents with repeated attacks of breathlessness is a recognised risk factor for bipolar disorders. On the other hand, depression can aggravate asthma symptoms. AIM: The aim of this study is to determine the indicators of the asthma control test (ACT) among the asthmatic patients who attend the outpatient clinic for follow-up and to investigate the relation between these indicators and clinical depression, using a standardised depression scale...

REVIEW

Cysteinyl leukotrienes (CysLTs) are potent lipid inflammatory mediators synthesized from arachidonic acid, through the 5-lipoxygenase (5-LO) pathway. Owing to their properties, CysLTs play a crucial role in the pathogenesis of inflammation; therefore, CysLT modifiers as synthesis inhibitors or receptor antagonists, central in asthma management, may become a potential target for the treatment of other inflammatory diseases such as the cardiovascular disorders. 5-LO pathway activation and increased expression of its mediators and receptors are found in cardiovascular diseases...

Asthma is a complex pulmonary inflammatory disease that can be promoted by air pollutants such as PM2.5 and formaldehyde (FA). However, existent experimental evidence principally focuses on the negative influence of a single air pollutant, neglecting the possible synergistic effect in biological responses to mixture of these pollutants, a more common situation in our daily life. In this study, allergic Balb/c mice were exposed to a mixture of PM2.5 and FA, and their toxicological effects and mechanisms were explored...

It is increasingly recognized that the bronchial asthma is a heterogeneous entity, encompassing a variety of different phenotypes. The identification of specific phenotypes is the key to develop more effective personalised treatment. The earliest attempt to phenotype asthma was proposed classifying into extrinsic and intrinsic subtypes. Clinical asthma is mainly divided into allergic (atopic) and non-allergic (non-atopic) asthma. Other phenotypes are based on trigger factors. Later the phenotyping based on the predominant cellular nature of inflammation: It can be divided into eosinophilic and non-eosinohilic...

PURPOSE OF REVIEW: Asthma is a heterogeneous disease characterized by multiple phenotypes. Treatment of patients with severe disease can be challenging. Predictive biomarkers are measurable characteristics that reflect the underlying pathophysiology of asthma and can identify patients that are likely to respond to a given therapy. This review discusses current knowledge regarding predictive biomarkers in asthma. RECENT FINDINGS: Recent trials evaluating biologic therapies targeting IgE, IL-5, IL-13, and IL-4 have utilized predictive biomarkers to identify patients who might benefit from treatment...

Leukotriene receptor antagonists (LTRAs) are identified as a monotherapy for asthma and allergic rhinitis; however, their use in children for treatment of these diseases has not been examined. Accordingly, the present study investigated the efficacy of pranlukast dry syrup for children with both pollinosis and asthma. The subjects were children receiving treatment for asthma who were also diagnosed with cedar pollen allergy. Patients were divided into a group that received continuous treatment with pranlukast (group A; n=20) and a group that commenced add-on treatment for pollinosis following the onset of symptoms (group B; n=20)...

BACKGROUND: A written action plan (WAP) reduces emergency visits for asthma exacerbations. However, a WAP is underused and often focused on asthma control. The innovation is an AppWeb that includes an expert software aimed at diagnosing the level of severity of asthma exacerbations and delivering a personalized digital action plan (DAP) when patients are in urgent need of medical advice. Symptoms describing the level of severity of asthma exacerbations and the consequent treatments have been established by working groups of the French Respiratory Societies (SPLF and SP2A for adults and children, respectively)...

BACKGROUND: Pulmonary conditions such as asthma and chronic obstructive pulmonary disease (COPD) are common conditions that warrant special consideration in the perioperative period. When these patients undergo surgical interventions, they have risk of complications such as bronchospasm, hypoxia, and even postoperative respiratory failure that warrants unplanned intensive care unit admission. Thus, clinicians must be familiar with pulmonary medication regimens that are critical for maintaining stable homeostasis of these chronic conditions...

OBJECTIVE: Systemic glucocorticoids (SGCs) are a treatment option for severe asthma but are associated with the development of adverse events (AEs). Evidence on the extent of SGC use and the relationship between SGC dose and AE risk in severe asthma is limited. METHODS: Patients with severe asthma (Global Initiative for Asthma step 4/5), with no SGC use during the <6-12 months before severe asthma determination (index date) were identified in the UK-based Clinical Practice Research Datalink database (2004-2012)...
