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: 1. 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 2. 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. 3. Determine whether a subgroup of symptomatic asthmatics, who show a greater benefit from PPI's, can be identified.
More and more general practitioners (GPs) use spirometry in their practices. At this time, there is sufficient reason to presume that, after a single postgraduate training program without any further support, most GPs have insufficient knowledge and ability to assure valid interpretation of their spirometry tests. Therefore, some kind of continuous diagnostic support with regard to spirometry interpretation by GPs is advisable. The aim of the present study is to assess whether implementation of spirometry expert support (either by a computerised expert system or a working agreement between general practitioners and respiratory consultants with respect to spirometry interpretation) causes changes in diagnosing and appropriateness and efficiency of medical care in subjects with chronic respiratory morbidity managed in general practice.
The purpose of this study is to determine whether asthmatics have different adenosine receptor expression profiles than healthy controls. We hypothesize that asthmatics will have increased adenosine receptor expression versus control subjects. We also want to study the effects of allergen inhalation on adenosine receptor expression in asthmatics. We believe that adenosine receptor expression will be upregulated after allergen inhalation. Both hypotheses are being tested in sputum and peripheral blood.
This study will determine the effects of montelukast on the duration of wheezing in children 12 months to 3 years of age who visit a physician for care of a wheezing illness. Only patients from the Ankara area of Hacettepe University Medical Center in Turkey will be included in this study.
Minority children who grow up in poor urban neighborhoods have the highest rates of asthma, and also experience greater morbidity from acute exacerbations of this disease. The aim of this study is to further identify environmental factors unique to the inner city that affect immune development and the expression of wheezing, atopy and asthma for purposes of identifying new strategies for asthma prevention.
