Filter by:The airways in the lungs get smaller the further into the lungs they go. Most simple measurements of lung function only reflect the larger 'central' airways and do not provide information on the smaller 'peripheral' airways. Newer measurements have been developed that can now give us accurate information on how the smaller airways are working. Indeed the small airways seem to play a significant role in asthma in terms of inflammation and airway narrowing. Recently, new types of inhaler formulations have been developed that have a much smaller particle size than other standard formulations. These formulations have been shown to go further into the lungs, thus getting into the smaller airways. In this study we aim to compare the two extremes of available long acting beta agonists in terms of particle size i.e. extra fine formoterol (Atimos) versus coarse particle salmeterol (Serevent)in asthmatics with abnormal small airway function using a breathing test called impulse oscillometry. By using this test we will be able to find out whether using an extrafine particle inhaler improves small airway function.
Asthma is the most common chronic pediatric disease in the United States, and is the most common cause of school absenteeism due to a chronic disease. Socioeconomically disadvantaged minority children receive disproportionately poor asthma care and incur a disproportionate share of asthma-related morbidity. The District of Columbia is particularly severely affected, with a lifetime asthma prevalence rate among children 0-17 years of age in 2010 of 22%, more than double the national average. One of the major challenges in treating asthma is poor adherence to daily controller medications, particularly inhaled corticosteroids (ICS) which are the cornerstone of the NIH guidelines for asthma management. In an attempt to overcome poor compliance, investigators in Rochester, New York have partnered with primary care providers in their community to arrange for ICS administration at school by school nurses, and this approach yielded significant improvements in several asthma outcomes. The investigators propose to collaborate in a pilot research project with the overall goal of improving asthma outcomes through reducing barriers to medication adherence. Specifically, the investigators aim to improve adherence to controller medications (inhaled corticosteroids - ICS) among DC children with asthma through the following activities: 1. A pilot prospective randomized clinical trial of home vs. school administration of ICS among DC children in grades kindergarten-8 with persistent asthma. 2. Qualitative interviews with nurses from DC public and public charter school to identify key barriers to administration of daily controller medications in the school setting
To determine if baseline asthma control influences susceptibility to pollutant-induced health effects in African-American children with moderate-to-severe asthma.
This study will compare the pharmacokinetic (PK) of Fluticasone Propionate/Salmeterol combination (FSC) 100/50 micrograms (mcg) delivered via the capsule-based inhaler (Rdpi) relative to FSC 100/50 mcg delivered via the multi-dose dry powder inhaler (Ddpi) to establish whether the Rdpi inhaler has exposure (in terms of fluticasone propionate area under time concentration curve [AUC] and Salmeterol maximum concentration [Cmax]) no greater than 1.2500 compared to the Ddpi, sufficient to allow progression to Phase 3. This study will enroll 36 healthy adult male and female subjects and each subject will be allocated to one of two sequences and will participate in four treatment periods, receiving each of the treatments twice.
This is the first study in human patients with asthma that the sponsor is conducting in order to evaluate if there are signals that the investigational medication, AXP1275, may be a safe and effective treatment for asthma. The results of this study may help the sponsor to design additional studies.
Distribution of neutrophils in bronchial mucosal tissue in asthma patients before and after 4 wk treatment with AZD 5069
Asthma and sickle cell disease each are serious medical problems. People with asthma have difficulty breathing, wheeze (a whistling noise when breathing), cough, produce sputum or phlegm, and have inflammation (swelling, irritation, redness) and narrowing of the bronchial tubes. When a person has both asthma and sickle cell disease together, more serious medical problems can occur such as having acute chest syndrome and pain episodes more often. It is sometimes hard to diagnose asthma in a person with sickle cell disease because sickle cell disease can also cause lung problems. The purpose of this study is to see if the investigators can better understand asthma when it occurs in a person who has sickle cell disease. The investigators will do this by taking a blood, urine, and saliva sample. The blood and urine samples will be analyzed for chemicals and DNA (genes). Certain genes can cause patients to have sickle cell disease or asthma. The investigators will use the saliva sample for future studies to compare the results from the blood testing with saliva. The investigator's long-term goal is to make sure people who have asthma and sickle cell disease are getting the best asthma treatments. The investigator's hypothesis is that the analysis of the blood, urine and saliva using a method called, metabolomics, may identify a unique asthma signature in children with sickle cell disease which may lead to targeted treatments.
The primary aim of this study was to compare the absolute and relative effectiveness of asthma management in paediatric patients in the UK on inhaled corticosteroid (ICS) maintenance therapy as extra-fine HFA-BDP (Qvar®) pressurised metered dose inhaler (pMDI) compared with fluticasone propionate (FP) pMDI.
This randomized, multicenter, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy, safety, and tolerability of lebrikizumab in adolescent participants with asthma whose disease remains uncontrolled despite daily treatment with inhaled corticosteroids (ICS) therapy and at least one second controller medication. Participants will be randomized in a 1:1:1 ratio to receive double-blind treatment with either lebrikizumab ('High' or 'Low') or placebo, administered as subcutaneous (SC) every 4 weeks (Q4W) for 52 weeks, in addition to their standard-of-care therapy. This will be followed by an optional 52-week double-blind active-treatment extension. The anticipated time on study treatment is up to 104 weeks. Participants who complete the study to Week 104, discontinue prematurely or decide not to take part in the optional active-treatment extension will transition to the 20-week safety follow-up period.
This proposal will address the existent gaps in the literature by identifying barriers and facilitators to participation in physical activity in inner-city minority elementary schoolchildren with asthma, more that half of whom are also overweight; developing and refining a school-based intervention in partnership with the community to improve physical activity; and conducting a pilot randomized controlled trial of the intervention to determine feasibility and obtain preliminary data for a future large-scale trial.
