Filter by:Randomized controlled trial of soluble fiber (NOVELOSETM 3490). Participants will complete an ASA 24 dietary recall questionnaire to access their fiber intake. If eligible for the study, participants will be supplemented to their target fiber dosage with either soluble fiber (NOVELOSETM 3490) or placebo. Collection of blood serum, fecal samples, and nasal wash will aid in analyzing the microbes present in one's gut and how fiber and diet may impact it. Thus, allowing researchers to better understand the pathways that may connect diet and asthma and if it is possible to improve asthma by altering one's diet.
Allergic asthma being the most widespread and easily identifiable phenotype, accounting for 60-80% of cases.Previous studies have reported that nearly 90% of patients with severe asthma were cases of allergic asthma, in which Immunoglobulin E (IgE) plays a critical role.Omalizumab was approved as an anti-IgE humanized monoclonal antibody for the treatment of patients with poorly controlled moderate-to-severe asthma, and was the first targeted drug used in the field of asthma treatment.The drug was launched in mainland China in August 2017.whereas,the clinical application experience, effects, and relevant data in the domestic population still lacking.The aim of this study was to observe the efficacy and safety of omalizumab, and to investigate whether baseline clinical characteristics and biomarkers can predicted response and adherence to treatment.
The study aims to investigate the relationship between the small molecule metabolite lysophosphatidylglycerol and asthma clinical features and explore its involvement in asthma pathogenesis.
Research has shown that adherence to evidence-based asthma guidelines leads to improved outcomes, yet critical gaps remain in the implementation of these guidelines, particularly among minority and low-income youth. Schools represent a crucial point of intervention, as demonstrated by school-based asthma programs that have addressed individual components of the guidelines with promising results. This project aims to develop, implement, and evaluate a pragmatic, multi-component asthma program that builds upon existing targeted interventions to fully implement the asthma guidelines and integrate them in school practices to foster sustainability. The investigator seeks to understand whether this type of program will improve asthma outcomes at the child and school level.
To optimize the effectiveness of asthma therapy there is a need to identify and address individual patient goals. Considering the self-management discussion as central for the achievement of health outcomes, Healthcare Providers may help patients make specific actions to obtain their desired goals. The current evidence suggest that Healthcare Professionals need to develop a more patient-centered and partnership-based approach based on the development and review of action plans, including the experiential asthma knowledge of patients and caregivers. From a practical perspective, the specialist (i.e. pulmunologists, allergologists, etc) has clear therapeutic targets to be reached in asthmatic patients: for example, improving the disease control, the spirometric values and asthma control test (ACT) score vs. pre-treatment evaluations represent the standard outcomes to reach (GINA 2019). However, as previously described, patients are more likely to achieve an improved clinical outcome when the treatment is driven by a personalized goal. This builds on the same principle as shared decision making between the physician and patient, recognizing both the personal motivation and the accountability on behalf of the patient (Hoskins et al. 2016). This study aims to evaluate if the identification of a personalized outcome allows patients to achieve a better control of asthma in terms of asthma control test (ACT) and asthma quality of life questionnaire (AQLQ). In addition, a set of clinical outcomes (i.e. forced expiratory volume in one second - FEV1, use of rescue therapy, night awakeness) will also be assessed.
The goal of this exploratory method-development study is to to establish and evaluate novel non-invasive methods to monitor airway inflammation induced by allergen challenge (both by instillation during bronchoscopy and by inhalation) in patients with mild allergic asthma. The investigator wants to further profile and develop the allergen challenge model by investigating the utility of various non-invasive monitoring methods. The hypothesis of the project is that local inflammatory changes in the lung induced by allergen can be captured by gas-enhanced magnetic resonance imaging (MRI) and analysis of exhaled breath. The validation of cellular outcome measures and non-invasive inflammometry can be used in future clinical trials for proof of concept of novel anti-inflammatory medications. Participants will undergo - methacholine challenge - 2 inhaled allergen challenges - 2 MRI with hyperpolarized xenon and gadolinium based contrast agent - 2 bronchoscopies with bronchoalveolar lavage (BAL) - segmental allergen challenge during the first bronchoscopy - spirometry - skin prick test and skin prick dilution tests - measurement of particles in exhaled air - nasal filter - nasal lavage - sputum induction - peak flow meter tests - exhaled NO (nictric oxide) - blood sampling (in total approx. 190 ml)
The goal of this clinical trial is to learn about how asthma influences brain function. The main questions it aims to answer are: - How airway inflammation in asthma affects the brain; and, - Whether airway inflammation in asthma is related to symptoms of depression and anxiety Over the course of 3 visits, participants will: - Complete questionnaires - Complete computer tasks - Undergo allergy skin test and breathing tests - Give two blood samples - Give a sputum sample - Complete brain imaging scans Researchers will compare results between participants with asthma, and participants who do not have asthma.
The primary objectives of this study are: - To determine the pharmacokinetic (PK) profile of fluticasone propionate (Fp) and albuterol sulfate (ABS), delivered in combination, from a single dose of TEV-56248 (Fp and ABS multidose dry powder inhaler with e-module [Fp/ABS eMDPI]) in participants with asthma - To compare the PK profiles of Fp for 2 different dose strengths of TEV-56248 to that of fluticasone propionate multidose dry powder inhaler (Fp MDPI) - To compare the PK profiles of ABS between the 2 different strengths of TEV-56248 The secondary objective is: • To evaluate the safety of a single dose of TEV-56248 and a single dose of Fp MDPI
Response to biologic therapies in severe asthma is variable, with patients being either non-responders, responders or super-responders. There is currently no explanation for this broad variation in response. It is important to examine whether these patients have distinct characteristics that could help the treating physician in making the correct diagnosis in clinical practice. Aim of this clinical study is to evaluate the efficacy of benralizumab, a humanized an anti-interleukin 5 receptor α monoclonal antibody in patients with severe eosinophilic asthma and to evaluate airway remodeling before and after benralizumab treatment. Hypothesis Identification of pathological and clinical characteristics in patients with severe eosinophilic asthma after benralizumab treatment regarding the airway remodeling, inflammatory cells, and other biomarkers on a long-term basis. Research questions Is there any improvement in airway remodeling? Are there any biomarkers to predict response to benralizumab treatment in severe eosinophilic asthmatic patients?
This study aims to assess the concordance of international asthma guidelines in the diagnosis of asthma and explore the presence of airways disease using additional non-guideline physiologic criteria, such as IOS (impulse osciollometry), not included in the guidelines, but available in the Portsmouth lung function service.
