Active clinical trials for "Asthma"

The degree of TH1-skewing by mycobacteria is controlles by NRAMP1 gene polymorphisms and related to the degree of inhibition of TH2-mediated disease.

Specific Aim: To determine whether a prescription for Inhaled Corticosteroids (ICS) added to standard Emergency Department (ED) discharge therapy for young children with persistent asthma symptoms increases ICS use and improves symptoms and quality of life over the months following the ED visit. Hypotheses: In a cohort of pediatric patients with persistent asthma discharged from the ED after an acute asthma exacerbation, a prescription for ICS will: Improve usage of ICS as measured by refill of a prescription within the first 2 months after the ED visit Improve symptom severity at two weeks after an ED visit as measured by days of cough, wheeze, missed school, daycare or work Improve patient and caregiver asthma-related quality of life during the 2 months following an ED visit measured by asthma Health Related Quality of Life (HRQL) Improve asthma control at 2 months as measured by a validated asthma instrument

In prior work, we found that even children who have been seen by their physicians within the prior six months were frequently misclassified as having mild rather than persistent asthma. This study evaluations whether systematic office-based screening assists primary care physicians in identifying children with significant asthma and improves preventive care for asthma. We hypothesize that standardized screening in the office setting will improve the physician's ability to (a) identify children with significant asthma and (b) prescribe appropriate preventive medications.

This single-center, randomized, double-blind, placebo-controlled trial was undertaken at an outpatient clinic in Shuguang Hospital. Newly diagnosed cough variant asthma adult patients with the T.C.M. pattern of pathogenic-wind are randomly divided into treatment and control group, with 60 patients in each group. Clinical observation of the Respiratory Impedance and Inflammation in Cough Variant Asthma adults reated in Combination of Chanqin Granules.

The goal of this study is to evaluate a sustainable, community-engaged program to reduce asthma disparities among 5 to 11-year-old children in Richmond, Virginia. Richmond, an urban center, has been named the Asthma Capital, or "most challenging place to live in the U.S. with asthma," by the Asthma and Allergy Foundation three times in the last 5 years. To date, however, the city has no comprehensive, community-engaged asthma care program for those children at highest risk for poor asthma outcomes. To address this disparity, the study team engaged with community partners and completed a mixed-methods needs assessment to enhance understanding of the barriers and supports to asthma care for children and their families living in Richmond. Several key priority areas emerged: peer support, advocacy, treating the home as a system, increased school nurse education, and coordination with schools and providers. Working together, the community-engaged team translated needs assessment findings to RVA Breathes, a program coordinating asthma care across 4 sectors: family, home, community, and medical care.

The purpose is to characterize the change of respiratory admittance induced by salbutamol inhalation in children and young adults. A variation threshold will be fixed to distinguish asthmatic and healthy subjects. This project could allow a better identification of asthmatic individuals needing a treatment, a reduction of morbidity of asthma, a reduction of unnecessary treatments administered in individuals with respiratory but not asthmatic symptoms, a better comprehension of bronchial hyperreactivity and its role in asthmatic disease.

The goal of this study is to help adolescents with asthma learn to control their illness and live without restrictions. We hypothesize that an intensive school-based asthma education program for students in 9th and 10th grade who have persistent asthma, together with asthma education for their primary care physicians, will improve the students' health status, quality of life, and ability to control their asthma through self-management.

The study null hypothesis is that vitamin D supplementation will not influence time to upper respiratory tract infection or time to severe asthma exacerbation in adult and adolescent patients with asthma.

The purpose of this study is to investigate the benefits of giving filled prescription of a medication to be used upon early onset of symptoms of URTI induced asthma. The hope is to reduce the need to present to Health Care centres for treatment.

The purpose of this research is to evaluate the methacholine challenge test as an accurate indicator of asthma in patients receiving treatment for asthma. Phase 1 on the study compares methacholine challenge test results from asthma patients to those from people who do not have asthma. In phase 2, test results for people with asthma on low dose inhaled corticosteroid will be compared to results on high dose inhaled corticosteroids. Both males and females with stable asthma (asthma participants) and without asthma (controls) enrolled. Participants will be between 12 and 69 years of age.
