Fiberoptic bronchoscopy is a procedure which involves passing a pencil-thin tube into the lung in order to collect fluid and cells from the airways. Fiberoptic bronchoscopy can collect cells from the walls of airways by gently brushing them (bronchial brushing). In addition, squirting small amounts of sterile water in to the airway and gently suctioning it back into the bronchoscope (bronchoalveolar lavage) collects cells. In this study, researchers plan to perform these tests on patients with asthma and normal volunteers. This research may help to improve the understanding of the processes involved in airway inflammation and asthma....

NCT07071194
Asthma is a common respiratory condition that can be difficult to control despite the use of medications such as inhalers, oral steroids or even injectable medications. Osteopathic Manipulative Treatment (OMT) is a hands-on technique used to improve the chest structure and function and may help in improving breathing. Previous research showed that OMT in asthma patients, can improve the movement of the ribs and improve the "peak flow" which is the maximum rate at which a person can exhale air after taking a deep breath. However, no studies have evaluated the impact of OMT on lung inflammation. This single-site research study at University Hospitals aims to evaluate whether Osteopathic Manipulative Treatment (OMT) can reduce lung inflammation and improve breathing and lung function in adult patients with asthma. The lung function will be evaluated by Spirometry which is a test that measures how much air you can breathe in and out of your lungs, as well as how quickly and easily you can exhale air. The lung inflammation will be measured using a device that can detect how much you are breathing out Nitric Oxide which is a gas produced by inflamed cells in the lungs, this test is called: Fractional exhaled Nitric Oxide or FeNO. Approximately 100 participants will be enrolled.

The goal of this observational study is to learn about clinical and functional outcomes in patients with Chronic rhinosinusitis with nasal polyps and comorbid Severe Eosinophilic Asthma and patients with Chronic rhinosinusitis with nasal polyps only treated with mepolizumab compared to healthy controls. Participants will be asked to give nasal, blood and sputum samples before mepolizumab administration (T0) and at 3 (T3), 6 (T6) and 12 (T12) months after mepolizumab initiation The main aims are to identify airways microbiota modifications and differential gene expression after mepolizumab initiation. Researchers will compare: * Patients with Chronic rhinosinusitis with nasal polyps and comorbid Severe Eosinophilic Asthma * Patients with Chronic rhinosinusitis with nasal polyps only * Healthy subjects The research will address the following questions: 1. What are the prospective clinical and functional outcomes of mepolizumab treatment 2. What is the impact of mepolizumab therapy on the airways microbiota and how this may relate to a potentially reduced need for steroids 3. What are the host differential gene expression patterns and the immune/inflammatory (cytokines/chemokines) profile alterations in airways microenvironment and in systemic circulation in response to therapy 4. What are the associations between host and microbiome variables for building up diagnostic and predictive biomarker classifiers of responsive disease endotypes
NCT07383896

NCT05440656
Severe eosinophilic asthma (SEA) is associated with poor disease control and compromised health-related quality of life (HRQoL), leading to a substantial psychosocial and economic disease burden. Benralizumab (Fasenra®), an interleukin (IL)-5-alpha receptor monoclonal antibody, is approved as an add-on maintenance treatment for SEA. This study aims at collecting real-world data that extend beyond the clinical effectiveness of benralizumab to the participant-reported impact of treatment on their HRQoL, sleep quality, depression, anxiety, work productivity and activity impairment, but also on treatment effectiveness. Recent technological advances in portable spirometers and wearable activity trackers (WAT) to increase physical activity for participants with asthma, even for older participants, allow this study to collect data on lung function parameters and physical activity from such devices for the first time at a country level in Greece. Using a multi-aspect approach, this study will generate real-world evidence on a broad range of both well-established clinical and novel patient-centered outcomes which are critical to the assessment of the therapeutic benefit both from the physician's and the participant's perspective. All main study outcomes will be examined at various timepoints throughout the course of the 48-week observation period, starting as early as 4 weeks after treatment initiation, thus enabling the identification of 'early' treatment responders with a closer focus on patients' physical and psychological well-being and HRQoL in addition to asthma control and lung function metrics

Our UH3 clinical trial, "Reducing Asthma Attacks in Disadvantaged School Children with Asthma," seeks broad-scale implementation of our effective school-based approach to improve asthma disparities for children, ages 5-12 years, in low-income communities. The investigators will contextualize dissemination and implementation (D\&I) of our Colorado school-based asthma program (Col-SBAP) that reduces asthma exacerbations and missed school days, while also addressing social determinants of health. Our Better Asthma Control for Kids (BACK) Program will evaluate key metrics identified by diverse stakeholders during this dissemination trial in rural and small metropolitan areas of Colorado. Our clinical trial includes two implementation strategies: our standard Col-SBAP, titled BACK-Standard (BACK-S) and an enhanced community-centered approach, titled Back-Enhanced (BACK-E). These two strategies are designed for sustainable delivery by school asthma navigators and school nurses who coordinate with primary care and community resources. The Exploration, Preparation, Implementation, Sustainment (EPIS) D\&I framework was applied with community partners during the UG3 planning phase to tailor implementation plans that meet local community needs, resources and priorities (EPIS Phases 1 \& 2). BACK-S and BACK-E will be delivered from years 1-3 with data collection for implementation and effectiveness outcomes in 4 Colorado regions. In year 4, the investigators will collect data for sustainment outcomes (EPIS phase 3). The investigators will apply the work from EPIS phases 1-3 to refine our "dissemination playbook" that guides adoption by other school systems (EPIS Phase 4). Our primary implementation hypothesis is: Reach will be greater among students when delivered using the BACK-E arm as compared to BACK-S. Our effectiveness hypothesis is: BACK will be more effective than usual care at reducing asthma exacerbations. The BACK playbook includes training materials and a calculation of return on investment. The investigators are targeting schools with high levels of uncontrolled asthma and asthma associated burden. Our UH3 trial includes partner engagement to ensure BACK is disseminated to diverse geopolitical areas of Colorado with attention to sustainability. Collectively, our approach will accelerate dissemination of BACK nationally to communities experiencing health inequities in pediatric asthma care.

NCT05366309
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.
NCT07500246
Asthma is one of the most common chronic diseases in children, and treatment success often depends on proper inhaler use and consistent medication adherence. Exposure to allergens and pollutants can also impact treatment response and asthma control. Moreover, there is a growing need for non-invasive biomarkers to support better diagnosis and personalized care. The goal of this clinical trial is to investigate if a new digital inhaler can improve inhalation technique and treatment adherence in children aged 5 to 16 years old, with partly controlled or uncontrolled asthma requiring treatment with inhaled corticosteroids. The main questions it aims to answer are: * Does the use of a digital inhaler improve adherence to inhaled corticosteroids and asthma control in children? * Which biomarkers could support diagnosis and help predict treatment responses in children with asthma? * How do environmental factors influence asthma control and treatment outcomes? Researchers will compare adherence to inhaled corticosteroid therapy between children using a new digital inhaler (Whizz spacer) and those using a standard, non-digital inhaler (AeroChamber Plus® Flow-Vu®) to see if the digital inhaler improves treatment administration and asthma control. They will quantify inflammatory markers in biological samples from asthmatic children and children without respiratory disease, to find biomarkers linked to disease and treatment response. Participants will: * Use the Whizz spacer or the AeroChamber Plus® Flow-Vu® during 12 weeks for corticosteroid inhalation, and complete daily a study diary to follow treatment administration. * Complete asthma control and quality of life questionnaires and have an evaluation of asthma control through GINA score at baseline, 6 and 12 weeks. * Undergo spirometry tests and FENO measurements at baseline and 12 weeks. * Give biological samples at baseline and 12 weeks. * Collect children's bedroom dust samples at baseline. * Wear a bracelet for 7 days at baseline and 12 weeks to monitor physical activity.
NCT01420133
Few recommendations concerning the diet and dosage to be administered to patients treated with corticosteroids are established. It therefore seems important to study prospectively the indication of a diet low in salt and sugar in patients undergoing corticosteroid therapy, to record side effects observed and to measure their frequency.
