Filter by:Severe asthma is a debilitating condition associated with frequent symptoms, life-threatening exacerbations and corticosteroid side-effects. Exercise limitation due to exercise-induced bronchoconstriction, dynamic lung hyperinflation and comorbidity may be a strong determinant of the disease burden. Mepolizumab is a monoclonal anti-interleukin-5 (IL-5) antibody that reduces the rate of severe exacerbations, asthma symptoms and oral glucocorticoid requirement, and improves quality of life and work productivity in severe eosinophilic asthma. However, its impact on physical activity and exercise tolerance is unknown. We hypothesize that a 6-month treatment with mepolizumab is associated with an improvement in daily life physical activity and exercise tolerance in relation with enhanced ventilatory mechanics.
A Randomised, Double-Blind, Parallel-Group, Placebo-Controlled 28-week Phase 3 Efficacy and Safety Study of Tezepelumab in Reducing Oral Corticosteroid Use in Adults with Oral Corticosteroid Dependent Asthma
Around 1/3 of patients with COPD have elevated eosinophil levels. However, the role of eosinophils in COPD has not been yet understood and is probably different in COPD and in asthma. The aim of this study was to assess the expression of selected surface markers on eosinophils and to assess the gene expression in eosinophils in COPD and asthma patients. We are planning to enrol 12 COPD, 12 asthma and 12 control subjects. Patients will undergo routine clinical assessment, spirometry, blood sampling and sputum induction. Eosinophils will be isolated from blood and sputum. Surface markers on eosinophils will be assessed in flow cytometry, gene expression will be assessed by RNAseq.
This study is a phase Ib/II clinical trial conducted in Chinese adult asthmatic subjects to evaluate the preliminary efficacy and safety of MG-K10 humanized monoclonal antibody injection in the treatment of asthma.
Asthma is a common disease which causes swelling in the airways, making it difficult to breathe. Asthma is common in children, affecting 1 in 11 children in the UK. Asthma is treated with inhalers which reduce the swelling. If inhalers are taken correctly they can help keep symptoms under control, allowing asthma sufferers to go about their day with less chance of having an asthma attack. Many patients have been found to not take their inhalers correctly and either under use (which leads to poor control of symptoms) or over use (which leads to potential side effects). Although asthma in most patients can be controlled with inhalers, not using inhalers correctly is one of the most common causes of poor control. This is common in children and young people (CYP) with all severities of asthma, resulting in high burden on the families and healthcare systems. The biggest challenge facing doctors and nurses helping CYP with asthma is finding a way to ensure that they take the medication. Whilst there are many studies looking into inhaler use, there are no large studies about how inhalers are used between clinic visits in CYP with asthma. The Smart Spacer is monitoring device which allows doctors to monitor when and how effectively inhalers are being used. This study wants to find out how well this device works, how well and how often CYP are using their inhalers, and if tailored education improves asthma control. To do this, participants in the study will be randomly selected to have "tailored education" or "standard care education". The investigators are inviting 100 children and young people (CYP) aged 6-18 years who have asthma to join this study.
Advances in understanding the pathophysiology of asthma development and severity have pointed towards a prominent role of the bronchial epithelium, especially in more chronic and severe disease. Studies suggest that airway eosinophilic inflammation in asthma is linked to epithelial injury and structural changes of the airways, co called airway wall remodeling. Together the chronic airway inflammation and remodeling are associated with bronchial hyperresponsiveness, fixed airflow obstruction or progressive loss of lung function and clinical severity of asthma. Chronic rhinosinusitis with nasal polyps (CRSwNP), is another respiratory inflammatory disease often co-existing with severe asthma, sharing similar pathophysiology. The investigators hypothesize that epithelial barrier integrity may play a role in the pathophysiology of severe eosinophilic asthma and nasal polyposis and in response to anti-IL5 therapy of severe asthmatics, and that shedding of epithelial barrier proteins may be used as biomarker in the management of severe asthma. In order to study that, the investigators will conduct a prospective cohort study of adult severe asthmatics with/out CRSwNP, who live on the island of Crete, Greece and who meet the criteria for entering anti-IL5 treatment, as assessed by pulmonologist. The participants will be recruited with a convenience sampling in a period of 2 years, under real life conditions, and will be followed up for 1 year after treatment initiation. A control group of subjects diagnosed with nasal polyposis without severe asthma will be used. Eligible subjects will undergo clinical assessment with radiological (CT) and endoscopic investigations. Samples of serum, sputum, nasal secretions, as well as nasal and bronchial biopsies will be obtain for assessing clinicopathological differences among the 3 groups but also response to anti-IL5 therapy in SEA w/o CRSwNP.
sRAGE is a recognized marker of alveolar injury in acute respiratory distress syndrome (ARDS). More recently, it seems to be an interesting marker in asthma. It is the soluble form of the pro-inflammatory RAGE receptor overexpressed in the lungs and in particular the bronchi. It acts as a decoy to its ligands, and thus blocks the pro-inflammatory axis of RAGE. Few studies are available in asthma, especially in children. A local study showed low levels of serum sRAGE in the context of acute bronchiolitis. The same finding emerges from the few studies available in asthma, with rates all the lower when the asthma is poorly controlled. A study carried out in the animal model in 2012 found an absence of inflammatory infiltrate, the absence of increased expression of mucin and the absence of mucus goblet cell hyperplasia within the respiratory epithelium in the absence of RAGE receptor in sensitized mice dust mites, after exposure to their allergen. One could imagine in the long term a potential therapeutic avenue by a substitution in sRAGE in this pathology. The objective of this study is to study the ability of the alveolar sRAGE level measured on broncho-alveolar lavage for assessment, to discriminate the clinical degrees of control of severe asthma in children.
The aim of this project is to study the effect of an intragastric balloon (IGB) on asthma control in obese patients. Obese patients with uncontrolled asthma will be recruited and randomly assigned to two intervention arms : an intragastric balloon combined with diet and exercise versus diet and exercise alone (control group). The primary endpoint will be the proportion of patients with an improvement based on an Asthma Control Questionnaire (ACQ) score ≥ 0.5 at 1 year compared to baseline.
To compare the effects of aerobic training and behavioural intervention to increase physical activity in the clinical control of asthma and in the quality of life of patients with asthma.
This is a randomized, assessor-blind, placebo controlled, multicenter, clinical endpoint bioequivalence study to compare the efficacy and safety of generic fluticasone propionate inhalation aerosol USP 44 mcg (Glenmark Pharmaceuticals Ltd) to Flovent HFA (fluticasone propionate inhalation aerosol) 44 mcg (GSK group of companies) in treatment of patients with bronchial asthma.
