Active clinical trials for "Asthma"

This will be a non-drug interventional cross-sectional study, where the screening visit and study visit can occur on the same day. Investigational product will not be administered. Approximately 790 subjects with severe asthma will be screened to achieve a total of at least 750 evaluable study subjects. The study will not include a run-in or follow-up period. This study will provide a more reliable description of the severe asthma patient landscape with respect to the potential eligibility for treatment with mepolizumab, omalizumab, and reslizumab. This study aims to estimate the potential overlap of patients eligible for treatment with mepolizumab and those eligible for treatment with omalizumab and/or reslizumab. Additionally, the current study will also ascertain and describe reslizumab eligibility with respect to both mepolizumab and omalizumab, in the severe asthma patient population.

The main purposes of this study are to evaluate the safety (Parts 1 and 2) and efficacy (Part 2) of pretreatment with CNTO 3157 in healthy adult and asthmatic adult participants before and after intranasal (into the nose) inoculation with human rhinovirus type 16 (HRV-16).

Overall goal: To apply the investigators' well defined simple, few-minute breathing/ mild physical exercise program and evaluate its efficacy/benefits for the improvement of clinico-immunological outcome in obese patients with asthma. Rationale & Hypothesis: Different breathing exercise regimens currently recommended are not well defined and in certain cases may worsen dyspnea or even trigger an asthma attack. Therefore, it is important to evaluate the overall usefulness of a breathing exercise as a therapeutic intervention of asthma. In this regard, the investigators have designed an easy, few-minute breathing exercise program as a treatment modality for asthma and to evaluate its efficacy in improving associated clinico-immunological symptoms. The investigators hypothesize that the investigators' well-designed breathing/mild physical exercise intervention for obese patients will help alleviate the stress and symptoms of asthma by reducing the chronic low-grade systemic inflammation and thus potentiate the beneficial outcome of medication to render a better control over the disease and to improve the quality of life in obese patients. Clinical relevance/Significance: The investigators expect that their exercise module will help reduce inflammation caused by asthma, and thereby relieving symptoms of asthma. If successful, this would allow regular individualized exercise module to be recommended as a part of therapy for people with asthma, which could possibly reduce the dosage as well as frequency of taking medicine that they need.

Dietary intervention efficacy trials are distinctly lacking in asthma research. This pilot study aims to provide effect size estimates and justification, clinical trial and intervention feasibility data, and procedural materials for a full-scale randomized controlled trial that will determine the efficacy and mechanisms of action of the Dietary Approaches to Stop Hypertension (DASH)-a recommended dietary pattern based on proven cardiovascular benefits-as adjunct therapy to standard care for adults with uncontrolled asthma.

This project aims to improve guideline-based asthma care using enhanced communication and screening tools, telemedicine and directly observed therapy of preventive medications in city schools. Web-based screening will be used to identify children with persistent or poorly controlled asthma and to send reports to the child's primary care doctor. Children in the SB-TEAM group will receive a telemedicine asthma assessment in school and be prescribed a daily preventive asthma medication to be taken through school-based directly observed therapy. The overall aim of this study is to evaluate the use of the SB-TEAM intervention for improving guideline based care, enhancing adherence to effective preventive medications and at reducing morbidity among young urban children with asthma.

Asthma is a common disease that affects people of all ages and has significant morbidity and mortality. Poor outcomes and health disparities related to asthma result in part from the difficulty of disseminating new evidence and paradigms of care delivery such as shared decision making (SDM) into clinical practice. This study will evaluate a novel mechanism for dissemination of an evidence-based SDM Toolkit for asthma care in primary care practices. The study is ideally suited to study dissemination methods because it will leverage a partnership between an established consortium of practice based research networks (PBRNs) and an advanced Medicaid Network. This study will evaluate a novel dissemination process (FLOW) to spread an Asthma Shared Decision Making Toolkit to practices within a Medicaid network using a consortium of practice-based research networks (NCNC). The knowledge gained from this proposal and the partnerships formed between practice-based research networks and NC Medicaid will facilitate widespread dissemination to almost 300 practices.

This study is about asthma and how the environment affects asthma. Scientists know that air pollution (such as cigarette smoke and other particles in the air) can make asthma symptoms worse. This research is being done to study how the health of a person with asthma responds to an air cleaner. The investigator hypothesize that an air cleaner will improve the health of persons with asthma.

Asthma is a disease of rapidly increasing incidence that already affects more than 17 million people in the United States alone. It has long been known that areas of severely reduced airflow occur in asthma and contribute significantly to the impairment of gas exchange in this disease. However, the extent to which local blood flow changes during an asthmatic attack is unclear. The purpose of this study is using Positron Emission Tomography - Computed Tomography imaging to evaluate how the blood flow changes in the lungs during an asthma attack induced by allergens.
