Filter by:We wish to investigate the effects of 3 weeks of orally administered fish oil supplements on the airway sensitivity (provoking dose to cause a 15% fall in FEV1, PD15) to inhaled mannitol (AridolTM). Mannitol, an osmotic stimulus has been demonstrated as a useful model for exercise-induced asthma. We also wish to investigate if there is any associated improvement associated with selected markers of airway inflammation that can be measured in the sputum, blood, urine and exhaled breath condensate. Oral fish oil supplements have recently been demonstrated to be effective inhibitors of exercise-induced asthma, in association with an inhibition of markers of inflammation, over a 3 week treatment period. This finding has important implications in the treatment of asthma as this is a faster and more effective improvement than what is seen with inhaled corticosteroids on exercise-induced asthma. This observation requires validation and further investigation. We wish to study this in two patient groups; (a) steroid naïve asthmatics taking beta2 agonist when required and (b) asthmatics taking regular inhaled corticosteroids < 1000 mcg/day.
This study aims at determining the patterns of asthma remission, the prevalence of these different patterns and the various factors associated with such remissions and possible recurrences of asthma, in order to determine the mechanisms involved in these processes. We therefore want to document these specificities in studying biopsies of subjects in complete remission of their asthma and those in only symptomatic remission of their asthma, in comparison with mildly symptomatic asthmatic subjects and healthy controls.

The purpose of this study is to study the effects of once daily inhaled ciclesonide at varying doses on exercise provoked asthma symptoms, fall in lung function after exercise and sputum characteristics.
To investigate the change in patient's asthma symptom control using ACQ scores after 4 to 6 weeks of Symbicort Turbuhaler (budesonide/ formoterol) in SMART approach.
The purpose of this study is to investigate the extent of Symbicort use in patients prescribed Symbicort as maintenance and reliever therapy.
This trial is conducted in Europe, Asia, Oceania and the United States of America (USA). This is a one-year clinical trial to compare the safety of inhaled preprandial human insulin to subcutaneous insulin aspart in subjects with type 1 or 2 diabetes and asthma.
To study the improvement in airway inflammation in children with asthma non-invasively with exhaled breath NO, a marker of inflammation, after therapy with nebulized budesonide as 0.5mg daily.
GW685698X is a novel glucocorticoid receptor agonist that is being developed as an orally inhaled treatment for asthma. In previous studies inhaled GW685698X was administered as a dry powder containing either lactose alone or lactose and cellobiose octaacetate. However, future dry powder GW685698X formulations will contain lactose and magnesium stearate. This study will be the first administration of this new GW685698X dry powder formulation in man and will provide safety and tolerability data to support the further development of this formulation.
Nebulized Magnesium Sulfate has been shown to be of benefit in adults with acute asthma exacerbations, though limited work has been done in the pediatric population. Current therapeutic questions include the effect of more than one dose of nebulized magnesium, the possibility of a sustained effect (greater than 20 minutes) after a treatment, the potential benefit in children younger than 5 years of age, and the use of an asthma score to re-assess patients after treatment with this medication. The purpose of this double-blind randomized placebo-controlled clinical trial is the evaluate the effect of multiple doses of nebulized magnesium sulfate versus saline in addition to standard asthma therapy on clinical asthma score and FEV1 in children 7 to 18 years of age with a moderate to severe acute asthma exacerbation. Our hypothesis is that nebulized magnesium sulfate, when added to traditional bronchodilator therapy, will improve acute asthma exacerbations more rapidly than standard therapy alone. The primary outcomes are asthma score and FEV1 values obtained after two nebulized magnesium sulfate compared to placebo treatments. This therapy will be supplemental to standard therapy of albuterol and ipratropium nebulized treatments and systemic corticosteroids. The secondary outcome is patient disposition (discharge home or hospitalization). Patients with known asthma will be approached for enrollment and informed consent obtained if the asthma score after the first albuterol treatment is "2" or greater. One hundred-seventy patients will be enrolled and randomized to either the treatment group or the placebo group. The change from baseline in asthma scores and FEV1 values will be compared among the control and treatment groups to assess for any benefit of the addition of nebulized magnesium sulfate to the treatment regimen.
