Active clinical trials for "Asthma"

Asthma is a chronic lung condition in children, and often requires hospitalization for acute exacerbations. Azithromycin has been used successfully in other chronic lung diseases, including cystic fibrosis. Despite limited clinical evidence, some pediatricians use azithromycin in children hospitalized with asthma, citing either treatment of atypical pathogens or its proposed anti-inflammatory properties. This study proposes a clinical trial to determine if azithromycin will shorten length of stay in children hospitalized with acute asthma exacerbations.

The purpose of this study is to evaluate the effects of a diet that is low in glycemic load and abundant in fiber, fruits, vegetables, legumes and omega-3 fatty acids ("anti-inflammatory diet") on pulmonary function in pediatric patients with asthma. The primary endpoint will be change in forced expiratory volume in one second in response to the diet intervention. Secondary outcomes will include additional spirometry measures, fraction of exhaled nitric oxide, and assessment of symptomatic asthma control. In addition, we will identify potential physiological mechanisms relating diet with lung function, including changes in systemic inflammation, insulin sensitivity, and intestinal microbiome composition.

The main objectives of the study are: 1. To unravel the importance of molecular phenotyping in predicting the response to classical anti-asthma treatment (leukotriene antagonists) The investigators have developed a non-invasive technique based on mRNA analysis of induced sputum that enables us to study airway inflammation in detail. This technique forms the basis for our current project based on the following hypotheses: Different molecular asthma phenotypes exist: a Th2 phenotype and a non Th2 phenotype as reported by Woodruff and colleagues (Woodruff PG et al). Sputum mRNA cytokine levels can be used to diagnose Th2 asthma and discriminate this from non-Th2 asthma. Based on our previous research and preliminary data that non-Th2 asthma can be further divided in Th17 asthma and Th1+Th2 asthma; besides these, a fourth group without Th2, Th17 or Th1 characteristics also exist. These subgroups have different responses to anti-leukotrienes.

This is a study of levalbuterol tartrate HFA inhalation aerosol MDI in pediatric subjects birth to ≤ 48 months of age who go to the Emergency Department (ED) or their physician's office with an acute bronchospasm. Subjects presenting to the ED or physician's office with an acute bronchospasm must have a history of reactive airways disease, based on subjects' parent/guardian report.

The purpose of this study is to determine whether disease management program is effective in preventing acute exacerbations in patients with unstable chronic obstructive pulmonary disease (COPD) or asthma.

This trial will test the efficacy and safety of ramelteon, a selective melatonin agonist, on patients with insomnia comorbid with asthma.

This 4-week clinical study evaluates the efficacy and safety of Albuterol Sulfate HFA Inhalation Aerosol in comparison with the Active Control, Proventil-HFA (3M Pharmaceuticals, Inc) in pediatric patients (4-11 years old) with mild-to-moderate asthma. In addition, pharmacokinetic profile in this population will be evaluated using a population PK approach with sparse blood samples.

This 12-week clinical study evaluates the safety and efficacy of Albuterol Sulfate HFA Inhalation Aerosol (Albuterol-HFA, or: A004), Armstrong's proposed HFA formulation of metered dose inhaler (MDI) of Albuterol (Treatment T), in comparison with: Placebo control: (HFA propellant only, Treatment P); and Active control: 3M/Key's Proventil-HFA (Treatment R). The treatments will be given as self-administered oral inhalations in adult and adolescent patients with mild-to-moderate asthma, for 12-weeks. Dosing regimen throughout the 12-week study is two actuations four times daily (QID).

The purpose of this study is to determine the efficacy of an anti-asthma herbal medicine intervention (ASHMI) in adult asthmatics

The purpose of this study is to determine whether macrolide therapy is effective in treating patients hospitalized with asthma exacerbations or chronic obstructive pulmonary disease (COPD)exacerbations. We hypothesize that compared to placebo, maintenance therapy with macrolides, when added to usual care, a) improves respiratory symptoms, b) improves quality of life, c) reduces airway inflammation, d) reduces airflow obstruction, and e) decreases the rate of re-exacerbations.
