Active clinical trials for "Asthma"

The goal of this research is to use Helium-3 MRI to see the changes in airflow of the lungs at different times of an attack. These three stages are immediately after the attack, 1 month later and 4-6 months later.

There are 7.1 million children with asthma. Asthma is the cause of 10.5 million missed days of school, 7.5 million outpatient visits, 640,000 ED visits, and 157,000 hospitalization visits in 2008. Recent work has demonstrated that trained peer mentors (individuals from the community) can be effective in reducing hospitalizations for asthmatic children. This study will evaluate the efficacy of technology-driven parent-to-parent mentoring to reduce asthma-related pediatric hospitalizations and emergency department visits.

The aims of this study is to evaluation of the clinical efficacy and stability of Information and Communication Technology (ICT)- based centralized monitoring system of asthma control monitoring in asthma patients. We planed to enroll 100 asthma patients (50 subjects using ICT systems, 50 controls). We will monitor the asthma control status, lung function, exacerbation rate and stability of ICT systems. This study is based upon work supported by the Ministry of Trade, Industry & Energy (MOTIE, Korea) under industrial Technology Innovation Program (No. 10059066, 'Establishment of ICT Clinical Trial System and Foundation for Industrialization').

ToAST study is a pilot study aiming to establish the safety profile of using inhaled capsaicin challenge in patients with severe asthma. The investigators will also explore the differences in cough symptoms and threshold in patients with and without bronchial thermoplasty.

The investigators hypothesize that aligning digital data on PEF and adherence with the patient's own clinical course achieves better asthma control and identifies risks for future loss of control, compared to current best practice. The study has an adherence optimisation phase, week 1-12 followed by a medication management phase, week 12 to week 32. The investigators will compare two asthma education interventions, standard Guideline recommended practice and feedback from the individual's own INCA device, which assesses inhaler adherence and relates adherence with changes in PEF and symptom scores over time. The study has two co-primary endpoints, one will be a comparison of the adherence to therapy and the other will be a comparison of the appropriateness of medication prescriptions between the two study groups.

Sputum induction is considered a relatively non-invasive, reliable procedure, which can be utilised to characterise the inflammatory profile of the airways. However, the procedure can be slightly uncomfortable for patients. This study aims to assess the differences in participants' tolerability of sputum induction, by comparing two different nebulisers when performing the procedure.

Single-center open-label randomized pilot study to assess the effectiveness and efficiency of a mobile technology based intervention for asthma and obesity control.

Health disparities in pediatric asthma persist, with Latino children demonstrating increased asthma morbidity. Middle school children with asthma have greater morbidity than children from any other age group and spend a majority of their day in school, where they must manage any asthma. The investigators developed and piloted a novel group-based intervention - ASMAS (Asthma Self-MAnagement in Schools) in two geographic areas with a high prevalence of urban and Latino children with asthma: Providence, Rhode Island, and San Juan, Puerto Rico. ASMAS is a 4-session, peer-facilitated asthma self-management intervention specific to the school setting for Latino middle school (6th-8th graders) children. It is delivered by trained High School Juniors and Seniors of Latino descent with asthma. The preliminary effects of ASMAS for improving asthma outcomes and self-management relative to controls were demonstrated in a previous intervention development study. This study will evaluate ASMAS through a large-scaled Randomized Control Trial with urban middle school students who have persistent asthma in Providence, Rhode Island and San Juan, Puerto Rico and will identify barriers and facilitators to the implementation of ASMAS. These results will inform future, large-scale dissemination in other urban school settings.

There are many symptoms associated with severe asthma, not all of them related to the lung. These are referred to as extra-pulmonary symptoms and their relationship with quality of life is complex. Body reprogramming (BR) is a non-drug intervention originally developed for fibromyalgia patients with the aim of improving health and wellbeing in a personalised way, with evidence-based lifestyle changes. The frequency and severity of multiple symptoms in severe asthma is similar to fibromyalgia and the investigators propose that BR may be a suitable non-drug intervention for severe asthma patients who are about to step up drug treatment. Our study aims are therefore to assess how BR may be suitable for people with severe asthma, and to adapt and optimise the programme for these people. In two phases, severe asthma patients will be recruited via a regional severe asthma clinic at the Royal Devon & Exeter NHS Trust and invited to take part in a short course of BR. In phase one, patients will be asked to attend four weekly researcher-led sessions of BR via video call and be given practice tasks to report on at the subsequent session. Questionnaires will be completed for the first and last session. At the end of BR, patients will also be invited to take part in a focus group. The data collected will inform development of the programme for phase two, which will involve recruitment of severe asthma patient who are about to start biologic drug treatment for their severe asthma

Chronic airway inflammation rich in eosinophils is an important feature seen in asthma. Airway and blood eosinophilia is associated with increased rates of asthma exacerbations and more intense treatment. Recently, the existence of two distinct eosinophils subtypes was revealed-lung-resident eosinophils (rEOS), which maturate independently to interleukin (IL) 5, with the primary function to maintain tissue homeostasis, and inflammatory eosinophils (iEOS), which mature in IL-5-dependent manner and are mainly involved in immune responses. Eosinophils' effect on the airway remodeling in asthma depends not only on the activity but also by their viable number in the lungs. Blood iEOS infiltrate the airways mainly after the environmental stimulus like allergen and leave the airways with bronchial secretions. However, rEOS reside lung tissue for their entire lifetime regulating local immunity. Blood rEOS and iEOS ratio alters in asthma, compared with healthy controls. It is known that the predominant eosinophils subtype in allergic asthma are iEOS, while rEOS are basic subtype in severe eosinophilic asthma patients, moreover, they are different in adhesive properties and survivability as well. Distinct biological properties allows to speculate about their different functions in asthma, however, there are still little information. Data about differently expressed microRNA (miRNA) profiles in eosinophils in asthma suggests, that eosinophils subtypes can be distinct in non-coding RNA (ncRNA) - microRNA (miRNA), piwi-interacting RNA (piRNA) and long non-coding RNA (IncRNA) profiles that could describe their role in asthma pathogenesis and act as biomarkers to discern asthma phenotypes.
