Filter by:There is a mounting body of evidence suggesting that there is a large disparity between the development and the actual implementation of guideline-driven asthma care in primary and specialty care practices. To address this disparity, the American Academy of Allergy, Asthma & Immunology (AAAAI) developed a unique, comprehensive and easy-to-use Web-based tool for clinicians who treat asthma patients called "Asthma Specialist Tool to Help Manage Asthma and Improve Quality" (Asthma-IQ). This study will examine whether the use of the Asthma IQ primary care tool will improve asthma care and asthma outcomes using a randomized trial of the Asthma IQ system versus usual asthma care in the primary care setting over 1 year. At the end of 1 year, all patients will be managed using the Asthma-IQ tool for an additional year to determine if the patients managed by usual care in the first year improve when managed in conjunction with Asthma-IQ. The primary endpoint to determine if the use of the Asthma IQ tool will improve asthma patient outcomes is quarterly assessments of Asthma Control Test (ACT) scores via automated / electronic patient survey. The secondary endpoint is asthma exacerbations and there are a number of exploratory endpoints to further define the clinical utility of the primary care version of Asthma-IQ. This study will involve recruiting approximately 20 family medicine offices with approximately 20 patients each, to conduct this randomized, multiple time point intervention trial. The necessary total recruited patient sample size is 200 per group. The results of this study will help determine the utility of Web-based tools to help manage chronic diseases such as asthma.
This study is designed to determine whether TC-6987 improves respiratory function in subjects with asthma by reducing airway hyper-responsiveness and inflammation.
Bronchial asthma is a common disease and frequently encountered disease of respiratory apparatus. It has very complex mechanism and multiple inducing factors. This study will focus on a new Chinese therapy on Bronchial asthma, analyzing the treatment mechanism of internal and external use, based on Traditional Chinese Medicine (TCM) theory and clinical practice. The study will also investigate the efficacy of the Chinese drugs and treatments on Bronchial asthma, and provide an effective therapy for this disease.
We are doing this study to learn how genes affect the way that people, specifically Black people, respond to treatment for asthma. Recent studies suggest that people respond differently to some asthma medications (eg Serevent, Foradil). Some people feel better when they use these inhalers, but others may not, and some people get worse. It seems that this difference shows up more often in Blacks than in Whites, which is why we are looking for Black subjects for this study. In all people, this difference seems to depend on their genes or DNA. This study is comparing the use of long acting asthma medications (Serevent, Foradil) to Tiotropium (Spiriva) for the treatment of asthma. Spiriva is used to treat chronic obstructive pulmonary disease (COPD). This study will help to see if this medication is also useful for treating asthma and whether it works better for some people than the current asthma medications.
Traditional, continuous-mode nebulizers such as the English-Wright nebulizer are designed to operate continuously with tidal breathing. As inhalation accounts for only about one-third of the respiratory cycle, two-thirds of the continuously produced aerosol is lost to the environment possibly posing a hazard any fellow-patients, family members, or health-care workers in the vicinity. The English-Wright has been the only American Thoracic Society (ATS)recommended device available on the market. Recently Roxon Medi-Tech has announced the discontinuation of the English-Wright nebulizer. For these reasons it is necessary to review the use of other nebulizers such as the AeroEclipse II breath-actuated nebulizer and further validate their performance. The investigators expect to show equivalence between the AeroEclipse II and the English-Wright nebulizers.
Research Title: The effect of vitamin D replacement on airway reactivity, allergy and inflammatory mediators in exhaled breath condensate in vitamin D deficient asthmatic children. Introduction: Vitamin D seems to play a role in allergic and asthmatic reactions as an immunomodulator. Asthma disease involves inflammatory process in the lower respiratory tract and airway hyperreactivity. Aim: To assess the effect of Vitamin D replacement on airway reactivity, and allergy and inflammatory mediators in exhaled breath condensate in vitamin D deficient asthmatic children. Design: Double blind placebo control prospective study comparing the effect of Vitamin D replacement and placebo on airway reactivity, allergy and inflammatory mediators in exhaled breath condensate in asthmatic pediatric population with vitamin D deficiency. Participant selection: The study group will consist of pediatric patients (age 6-18 years) followed and treated at the Pediatric Pulmonary Unit at the investigators hospital. Patients with mild-moderate asthma with low or insufficient vitamin D levels that are currently not receiving anti-inflammatory treatment will be recruited. Sample size: 60 participants in the two groups (30 receiving Vitamin D and 30 receiving placebo). Intervention: Vitamin D (14000 units) or placebo will be provided in a similar appearance preparation once weekly for 6 weeks between visit two and three. Three visits will be conducted. Each subject will undergo evaluation including a respiratory questionnaire (visit 1), methacholine challenge test with determination of PC20 (visit 1 or 2 and visit 3), exhaled nitric oxide (eNO) (visit 2, 3), and exhaled breath condensate (EBC) (visit 2,3). Venous blood will be analyzed for complete blood count + eosinophils (visit 1, 3), IGE levels (visit 1, 3), and Vitamin D levels (visit 1, 3). Prick skin test for inhaled allergens will be performed (visit 2, 3). Primary end point: Airway reactivity as assessed by methacholine challenge test. Secondary outcome parameters: All other parameters are the secondary end points.
This study will compare the absolute and relative effectiveness and cost-effectiveness of asthma management in patients in the USA on inhaled corticosteroid (ICS) maintenance therapy as HFA-BDP (Qvar®) pressurised metered dose inhaler (pMDI) compared with fluticasone propionate (FP) pMDI. .
This study will be a repeat-dose, double-blind, randomized, placebo controlled, three-way crossover study in patients with persistent bronchial asthma to compare the effect of morning (AM) and evening (PM) dosing with fluticasone furoate (FF)/Vilanterol (VI) inhalation powder on lung function. Following screening there will be a run-in period of 14 days. There will be 3 treatment periods; drug at AM, drug at PM and placebo, which will last for 14 days each with a 14-21 day washout period between starting the next. Key assessments include; forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), vital signs, electrocardiograms (ECGs), adverse event (AE) monitoring and laboratory safety tests.
This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy, safety, and immunogenicity of treatment with reslizumab in patients with eosinophilic asthma.
This is a six-month non-interventional prospective study of various controller therapies in children with asthma in outpatient clinical practice.
