Filter by:Clinical, Airway Inflammatory, and HRA Phenotypes, in preschool children with acute asthmatic attack presenting to the ED. Background: Children under the age of 5 years have the highest hospitalization rate of asthma. The most common causes of acute exacerbations of asthma requiring urgent medical care are viral respiratory infections. Most of these children < 6 y old are not atopic. The inflammatory response to these mostly viral-induced asthmatic attacks is not well characterized in the literature. Moreover it is not known whether different kind of inflammatory responses exist in this population and how this correlate to clinical outcomes and clinical phenotypes in preschool children presenting ti the ED with acute asthmatic attack. Therefore, the purpose of the present study is to: Investigate the characterization of induced sputum cytology in preschool children with acute asthmatic attack and whether there is correlation between specific sputum cytology and response to therapy and to investigate airways hyper-responsiveness to adenosine 5'-monophosphate and to metacholine in pre school children 2-6 y old at 2 weeks and at 3 month following acute asthmatic exacerbation and look for correlation with response to treatment and sputum cytology. Clinical phenotypes of this patient population will also be investigated.
This study is a randomized, active- and placebo-controlled, single-dose, seven-arm, crossover and dose-ranging design. This study aims to evaluate the efficacy and initial safety profiles, and to identify the optimum dose of A006, from a select dose-range for future clinical PK/PD and Phase III studies. This study is to be conducted in generally healthy, adult subjects who have mild-to-moderate persistent asthma for at least 6 months prior to Screening.
The aim of this trial is to evaluate the efficacy and safety of 2.5 and 5 mcg tiotropium over a 24-week treatment period as compared to placebo and salmeterol (50 mcg twice daily). Tiotropium inhalation solution delivered by the Respimat® inhaler will be examined on top of maintenance treatment with inhaled corticosteroid controller medication in patients with moderate persistent asthma. Efficacy and safety will be assessed by measuring effects on lung function, effects on asthma exacerbations, effects on quality of life, effects on asthma control, effects on health care resource utilisation, and number of adverse events.

The purpose of this study is to determine whether an inhaled steroid with a small particle size can be an additional treatment option in patients with refractory eosinophilic asthma.
This is a research study that compares the effectiveness of a web-based program (known as Puff City) and another web-based program (of internet sites such as the American Lung Association, American Academy of Asthma, Allergy, and Immunology, etc) that targets five key asthma management issues among rural youth: 1. Improving adherence to asthma controller medication use; 2. Improving compliance of carrying a rescue inhaler at all times for use at the first sign of asthma symptoms; 3. Improving inhaler technique; 4. Smoking reduction or cessation in those who are smokers; and 5. Avoidance of second-hand smoke exposure.
The purpose of this study is to investigate the efficacy and safety of procaterol hydrochloride with inhaled glucocorticoid in treatment patients with cough variant asthma (CVA).
Inner-city African American and Hispanic adolescents suffer from disproportionately high rates of emergency room visits and hospitalizations for acute exacerbations of asthma. This study proposes the use of a coping peer support intervention, enhanced by a technology-based platform that infuses peer support throughout adolescents' daily routines, to increase adherence to daily controller medications and ultimately reduce asthma exacerbation risk in this important population subgroup.
Spirometry is a recommended component of asthma diagnosis and treatment in the primary care setting, yet few providers report its routine use for children with asthma. Misclassification of asthma severity occurs when assessment is based on symptoms alone. This misclassification can lead to inadequate treatment, increased morbidity, and increased healthcare utilization/cost. The goal of this study is to test the effectiveness of a distance learning quality improvement program called Spirometry 360 developed by the interactive Medical Training Resources (iMTR) group at the University of Washington Child Health Institute. The Spirometry 360 program aims to improve care for children with asthma by enhancing provider knowledge and self-efficacy related to the use and interpretation of office-based spirometry.
The overall goal of this proposal is to examine the efficacy of a school-based asthma telemedicine intervention in a predominately minority, low-income rural pediatric population.
