Filter by: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.
Bioequivalence study between two inhaler products of ffluticasone propionate inhalation powder
Asthma is a complex condition that can impair not only the child's physical growth but also his optimal functional capacity and performance. Buteyko Breathing Technique (BBT) is an exercise designed to regulate the breathing process. The Buteyko technique also proposes lifestyle changes beyond breathing, including diet, allergy avoidance, and stress control. This study aims to evaluate the effect of the Buteyko breathing technique on asthma severity control among school-age children. In Egypt, this technique was applied through five studies, four among adult patients and only one among children. At Mansoura University, only one study was conducted among adult patients, and no studies were conducted among children. To fulfill this knowledge gap, it is necessary to study the effect of this technique on asthma severity control among school-age children. This study will use the Childhood Asthma Control, Peak Expiratory Flow Rate, and Control Pause tests to evaluate the children's asthma severity control.
Benralizumab is a humanised, afucosylated, monoclonal antibody that binds specifically to the human interlukin-5 (IL-5) receptor alpha subunit (IL-5Rα) of target cells such as eosinophils and basophils (Takatsu et al, 1994; Toba et al, 1999; Pelaia et al, 2020). Benralizumab was generally well tolerated by patients in clinical trials, with no apparent safety concerns. This study shall be conducted at 10 centers across India. The primary outcome measures will be - Percentage of AEs a, SAEs, and TEAEs - Nature, incidence, and severity of AEs including unexpected adverse drug reactions - Percentage of patients with AEs that lead to study treatment discontinuations.
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.
The purpose of the study is to assess the relationship between body posture and dynamic balance in adults with childhood-onset asthma and compare them to a non-asthmatic control group matched for gender, age, weight, and height.
This is a 3-part, parallel group treatment, Phase 1, randomized, double-blind, placebo-controlled study to assess the safety, tolerability and pharmacokinetics after sequential single and multiple ascending doses of SAR443765 in healthy adult participants, and after a single dose of SAR443765 in participants with mild-to-moderate asthma.
The aim of this study is to investigate the associations between serum IL-38 levels and different variables of asthma in children such as laboratory variables, pulmonary function test results, the diagnosis of asthma, and in correlation with disease severity.
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.
