Filter by: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: 1. Improve usage of ICS as measured by refill of a prescription within the first 2 months after the ED visit 2. Improve symptom severity at two weeks after an ED visit as measured by days of cough, wheeze, missed school, daycare or work 3. 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) 4. Improve asthma control at 2 months as measured by a validated asthma instrument
The purpose of this study is to determine if treatment with anti-IL-5 antibody has a prednisone-sparing effect in patients with symptomatic eosinophilic bronchitis (with or without asthma).
To investigate the validity of a clinical model to determine the relative potency of different preparations of inhaled corticosteroids used for the treatment of asthma or of eosinophilic bronchitis without asthma.
Asthma is a chronic respiratory condition characterized by bronchial hyper-responsiveness secondary to abnormal inflammation of the lung. Steroids remain the most effective treatment for this condition. The lipid lowering agents statins have been found to have anti-inflammatory properties. This study is to test the hypothesize that statins will decrease bronchial hyperresponsiveness and inflammation, leading to improved symptoms in patients with asthma.
This double-blind, stratified, parallel group study is to determine whether aiming for 'Total control' results in better airway hyper-responsiveness than maintaining the treatment level at which 'Well-controlled' asthma was achieved. The primary endpoint is the mean change in PC20 methacholine. Well controlled subjects (as assessed after a 12 week run-in period) will enter a 24 week treatment period during which they will record PEF(Peak Expiratory Flow), symptoms, rescue beta2-agonist use over 24 hours, night time awakenings, asthma exacerbations, emergency visits due to asthma and Adverse Events. At every visit lung function measurements and airway hyper-responsiveness will be measured.
The primary objective is to compare the efficacy of Symbicort Single inhaler Therapy with treatment according to conventional best practice in adolescent and adult patients with persistent asthma.
This is a 3-week study to evaluate FEV1 following treatment with drugs in persistent asthma which is also active during allergy seasons in pediatric patients with seasonal aeroallergen sensitivity.
A new artificial lung device has been developed that potentially provides added support to mechanical ventilation for severely damaged lungs. The Hattler Respiratory Assist Catheter is designed to provide gas exchange (deliver oxygen and remove carbon dioxide) for a period of up to 7 days, providing more time for the lungs to improve. Extrapolating from large animal data, the hypothesis is that the Hattler Catheter will be capable of providing 30% to 40% of the basal requirements of carbon dioxide exchange in a manner that is dependable and reproducible.
To compare the effects of formoterol alone (Oxis® TurbuhalerÒ) and the fixed combination of formoterol and budesonide (Symbicort® TurbuhalerÒ) on airway responsiveness as a marker of inflammation, induced by repeated low-dose allergen challenge in allergic patients with mild asthma
Ozone can cause acute airway inflammation in both asthmatics and normal volunteers. However, in asthmatics ozone can cause episodes of worsening of asthma. We want to learn if chronic allergic response, known as "IgE-induced airway inflammation" is what causes the increased inflammation in response to ozone. To do this we will examine the response to ozone in a group of asthmatics treated with omalizumab, a medicine available and approved for use in people with asthma, or a placebo control. The placebo for this study is inert physiologic saline ("salt water") which contains no omalizumab. Both the omalizumab and the placebo will be administered as an injection under the skin. Omalizumab, also called Xolair, is a humanized monoclonal antibody, which means that it originally was produced in mice, then genetically engineered to look more like human than mouse antibody. Omalizumab inactivates IgE, a protein our own immune systems make as part of allergic reactions. The purpose of this study is to test the hypothesis that omalizumab, by blocking this aspect of allergic reactions, will decrease the number of inflammatory cells in the airway after ozone challenge. We also hypothesize that omalizumab will decrease the effects of ozone on changes in lung function, mucociliary clearance (a measure of how quickly mucus clears form the airway) and airway reactivity. Airway reactivity is a measure of how sensitive the airways are to a medication used to diagnose asthma, called methacholine. We will examine these as additional information we can learn during the course of the study. This is a blinded study, meaning that neither you nor the researchers know if you get the active drug or placebo, but that information can be obtained if needed. The placebo is an injection of inert physiological saline ("salt water") which contains no omalizumab.
