Filter by:In this study, the investigators hypothesize that the reference product (SalbR/Ventolin) is more effective than SalbG (Salbutamol Sandoz) at improving the lung function in children with asthma, and that this difference increases alongside the severity of the airway resistance. (Null hypothesis: There is no difference). This could be explained by different properties and deposition of the aerosol. Purpose of this research: Rejecting the null hypothesis. This is based on the answers to the questions below. Research questions: 1. Is there a difference between the increase in FEV1 (and FVC) after 100 μg SalbG versus FEV1 after 100 μg SalbR in children aged 4-14 years with insufficient asthma control? (primary question) 2. Is there a difference in the subjective feeling of the children after inhalation with 100 μg SalbR and after 100 μg SalbG, measured with a VAS score? 3. Is the increase in FEV1 (and FVC) in children with asthma between 4-14 years of age with insufficient asthma control after inhalation of 400 μg SalbR different than after inhalation of 400 μg SalbG? 4. Is there a difference in the subjective feeling of the children after inhalation with 400 μg SalbR and after 400 μg SalbG, measured with a VAS score?
This study was a multicenter, open, observational study and was divided into two stages; Stage I study includes patients with suspected asthma to observe the diagnostic value and safety of Methacholine Choline Provocation Test. All patients clinically evaluated for bronchial provocation testing were included in the stage II study to further validate the diagnostic value and cutoff value of the methacholine choline provocation test.
The goal of this observational study is to learn about the agreement between sensors analyzing algorithm and body plethysmography in measuring oral and nasal breathing in healthy adults, and in patients with chronic rhinosinusitis, asthma and chronic obstructive pulmonary disease. The main question it aims to answer is: • Is the algorithm-based method accurate enough in analyzing respiratory obstruction as compared to body plethysmography (reference method)? Participants will perform a short breathing protocol (oral and nasal breathing with different masks) during which time their breathing is monitored with both methods.
The purpose of this study is to analyze the accuracy of respiratory and breathing patterns generated through impedance changes generated by a patch-type electrocardiogram device (HiCardi+ wearable patch device, Mezoo Co., Ltd.), targeting patients undergoing pulmonary function testing and ventilator application.
The study is being conducted to evaluate the effect of 3 dosing regimens of povorcitinib on pulmonary function
The goal of this clinical trial is to study if starting bi-level positive airway pressure (BiPAP), a mask that gives pressure to the lungs, works well for children in the emergency department with moderate to severe asthma attacks. The main questions it aims to answer are: 1. Whether initiation of BiPAP at the same time as continuous beta-agonist therapy (e.g., nebulized albuterol) will decrease how long children with moderate to severe asthma attacks need to receive continuous beta-agonist therapy. 2. Whether early BiPAP changes how the lungs function in children with asthma attacks. 3. Whether children receiving early BiPAP experience more issues or side effects than those children who do not. All children will receive the usual treatment for asthma attacks; if they are still experiencing moderate to severe symptoms after the initial treatment, they will be asked to participate in the study. Participants will then wear a mask while they are receiving the continuous beta-agonist therapy. Some patients will receive BiPAP where pressure is given to the lungs and others will have a sham BiPAP mask where no pressure is given to the lungs. Study participants will wear the mask for 4 hours or until their treatment team feels they are ready to come off of the continuous beta-agonist therapy. Participants will receive more medications and decisions on going home or being admitted to the hospital will be decided as usual by their treatment team. Researchers will compare BiPAP versus Control (Sham BiPAP) groups to see if there is a difference in how long continuous beta-agonist therapy is needed, how the lungs are functioning, and number or type of side effects.
Benralizumab is a relatively new treatment that is approved by NICE (National Institute for Health and Care Excellence, https://www.nice.org.uk/) for patients with severe asthma who have ongoing eosinophilic inflammation that remains poorly controlled despite high dose inhaled glucocorticosteroid medication. Eosinophils are a type of white blood cell that are linked to allergy and inflammation and are raised in people with severe asthma. Severe asthma is associated with a type-2 (T2) inflammation phenotype characterised by increased T2 cytokines (IL-13, IL-4, IL-5). Increased levels of eosinophils can cause inflammation in the lungs, increasing the risk of asthma attacks. The standard treatment for asthma involves taking inhaled glucocorticosteroid medication which primarily work by suppressing eosinophilic inflammation in the lungs. Benralizumab is a monoclonal antibody that targets a receptor on the surface of eosinophils called interleukin-5 receptor-α (IL-5Rα) leading to the rapid death of these cells and consequently a reduction in airways inflammation. In clinical trials, benralizumab has been shown to reduce both symptoms and the number of asthma attacks suffered by those with severe eosinophilic asthma. However, it remains unclear whether this clinical efficacy relates purely to the removal of the eosinophil, or additionally to the impact of this on other parts of the immune system. The BEUTI study will examine the structure and function of airway cells in patients with severe eosinophilic asthma. Particularly how the immune function of these cells changes with treatment and whether benralizumab leads to a reduction in T2 mediators and/or activation in airway cells. The aim is to take samples of cells from the airways during a bronchoscopy (a camera test looking into the lungs) before starting benralizumab and after 12 weeks of treatment. These investigations will allow us to better understand how benralizumab affects the cells within the airways and the pathways involved.
The investigators propose a randomized controlled trial of Telehealth-Enhanced Asthma Care for Home After the Emergency Room (TEACH-ER) vs. enhanced care (EC). TEACH-ER includes: 1) brief, pictorial, and health literacy-informed asthma education in the ED, with color- and shape-coded labels provided for home asthma medications; 2) virtual primary care follow-up within 1 week of discharge using in-home telemedicine (Zoom), featuring provider prompts for guideline-based preventive therapy and home delivery of prescribed medications with pictorial action plans; 3) two additional in-home virtual visits to reinforce teaching, review treatment plans, label medications, and support effective management practices. The investigators will enroll 430 children (ages 3-12 yrs) from the two dedicated pediatric EDs in our region, and follow all participants for a 12-month period. The investigators will call caregivers to complete blinded follow-up telephone surveys at 3, 6, 9, and 12 months after discharge. The investigators will assess the effectiveness of TEACH-ER in reducing the need for additional asthma-related ED visits or hospitalizations in the 1-months after enrollment. Additional outcomes of interest include asthma symptoms, medication adherence, absenteeism from work and school, quality of life, and the delivery of care consistent with national asthma care guidelines.
The purpose of this study is to investigate the relationship between long-term use of systemic steroids in patients with upper and lower respiratory tract diseases and their own production of cortisol (cross-sectional), as well as whether those with low cortisol levels have an impact on bone density. As patients with CRSwNP have a high use of steroids, they routinely undergo a DEXA scan at the Respiratory Clinic, Department of Ear-Nose-Throat Surgery and Audiology (ENT) - Rigshospitalet (RH) to examine whether their bone density and structure are affected. The scan will be included as a clinical secondary outcome to assess whether systemic steroid use has an impact on this. The purpose of the study is therefore to compare steroid intake, baseline P-cortisol, the body's response to ACTH (measured by cortisol levels after the test), and bone density in patients with chronic sinusitis (CRS) with and without asthma in an unselected population at the Respiratory Clinic (cross-sectional). In addition, at the 4-month follow-up (exploratory follow-up, pilot project), it will be investigated whether good adherence (>80%) to inhalation therapy (nasal steroid and lung steroid) and additional treatment with biologicals has a negative effect on the body's own production of P-cortisol.
The overall aims of this study are to develop and pilot test BRief intervention to Evaluate Asthma THErapy (BREATHE)-Peds, a dyadic shared decision-making intervention, to improve asthma by supporting self-management among racial and ethnic minority early adolescents receiving care for uncontrolled asthma in federally-qualified health centers (FQHCs) in urban communities. Aim 1 (Phase I) involves developing the intervention through focus groups with early adolescents and caregivers. Aims 2 and 3 (Phase II) involve preliminary testing of the intervention through a pilot randomized controlled trial. This record is for Phase II and III only
