Active clinical trials for "Asthma"

Asthma and gastroesophageal reflux disease (GERD) are common disorders, which although are not usually lethal, both have high morbidity, and high healthcare costs. Recent studies have demonstrated that asthma and GERD often co-exists, and that this co-existence is more frequent than just chance. Therefore, studies that characterize associations between these conditions, and, help in the development of interventions will positively impact the outcomes of these patients, which are critically needed. Subjects that participate in this study are required to be between the ages of 4-11 years old. This protocol proposes to enroll 100 children with asthma, on inhaled steroids who have poor asthma control, defined on the basis of frequent symptoms, excessive beta-agonists use, or frequent asthma episodes. The purpose of this research study is to: Determine, whether children with symptomatic, poorly controlled, asthma assigned to treatment with a PPI( Proton Pump Inhibitor), have fewer asthma exacerbations than similar participants assigned to placebo for a similar duration of time Determine whether children treated with Lansoprazole ( i.e., proton pump inhibitor): have a longer time to first exacerbation, have improved lung function, improved asthma symptom scores, improved quality of life, decreased rescue inhaler use, or other asthma medications, reduced emergency room/urgent care/ physician office visits that are asthma related. Determine whether a subgroup of symptomatic asthmatics, who show a greater benefit from PPI's, can be identified.

Introduction COPD and Asthma affect more than 10% of the population. Most patients use their inhaler incorrectly, mainly the elderly, thereby becoming more susceptible to poor clinical control and exacerbations. Placebo device training is regarded as one of the best teaching methods, but there is scarce evidence to support it as the most effective one to improve major clinical outcomes. Our objective is to perform a single-blinded RCT to assess the impact of this education tool in these patients. Methods and Analysis A multicentre single-blinded RCT will be set, comparing a placebo-device training programme versus usual care, with a one-year follow-up, in elderly patients with Asthma or COPD. Intervention will be provided at baseline, and after 3 and 6 months, with interim analysis at an intermediate time point. Exacerbation rates were set as primary outcomes, and quality of life, adherence rates, clinical control and respiratory function were chosen as secondary outcomes. A sample size of 146 participants (73 in each arm) was estimated as adequate to detect a 50% reduction in event rates. Two-sample proportions Chi-squared test will be used to study primary outcome and subgroup analysis will be carried out according to major baseline characteristics. Discussion The investigators expect to confirm that inhaler performance education will significantly reduce exacerbation rate and improve clinical and functional control. Ethics and dissemination: Every participant will sign a consent form. A Data Safety Monitoring Board will be set up to evaluate data throughout the study and to monitor stop earlier criteria. Identity of all participants will be protected. Results will be presented in scientific meeting and published in peer-reviewed journals.

The purpose of this investigator-initiated study is to evaluate the effects of oral curcumin supplementation versus placebo in adult patients with moderate to severe asthma. Curcumin, a derivative of turmeric, has been shown in animal models to inhibit the secretion of pro-inflammatory cytokines and decrease airway constriction and hyperreactivity with only a few observational studies available in humans with discordant results.

This is the first-in-human phase 1 trial of TQC2731 injection in healthy subjects and in patients with severe asthma to evaluate the safety, tolerability, pharmacokinetic characteristics and immunogenicity.

The purpose of the proposed study is to determine whether the addition of inhaled corticosteroids to treatment with oral corticosteroids and albuterol would reduce repeat emergency department (ED) visits among patients treated for acute exacerbations of asthma and COPD discharged from the emergency department to home. The investigators hypothesize that patients treated with inhaled corticosteroids in addition to oral corticosteroids and albuterol will have lower rates of 30-day return visits to the emergency department than those patients treated with oral corticosteroids and albuterol only.

The purpose of this study is to determine whether nebulized magnesium sulphate is effective in the treatment of acute severe asthma when comparison with intravenous magnesium sulphate

This is a pilot randomized controlled trial of lower vs. higher dose vitamin D supplementation in D-deficient asthmatic children, to determine necessary sample sizes for outcome measures in a larger multisite study, and to examine possible relationships and effect sizes between various biological markers that may be important to the pathophysiology of childhood asthma. Aims of the study are to: Evaluate effect sizes for relationships between serum 25OH-vitD and omega-fatty acid (FA) biomarkers, before and after supplementation with lower or higher dose vitamin D, on immune function, and asthma severity. Characterize changes in innate and adaptive immune function and inflammatory responses in asthmatic D-deficient youth at baseline and after vitD supplements, by dietary O6:O3FA status and vitD dose.

Exercise training has been proposed as adjunctive therapy in asthma to improve many clinical outcomes; however its effects on bronchial hyperresponsiveness (BHR) and inflammation, characteristic features in asthma, remains poorly understood. We aim to investigate the effects of aerobic training on BHR (primary aim) and systemic inflammation (secondary aim). In addition, clinical control and health related quality of life (HRQoL) will be also assessed.

This randomized controlled study aimed to evaluate the efficacy and safety of acupuncture therapy on persistent allergic rhinitis patients complicated with asthma.

The trial aims to record possible effects of a supplementary treatment with ivy leaves dry extract on different lung function parameter, on bronchial hyperreactivity, on individual markers of asthmatic inflammation and on the clinical symptom profile. The hypothesis is, that the additional therapy might improve these parameters and might help to optimize asthma therapy.
