Filter by:A post-marketing study to look at the effects of Asmanex on markers of airway inflammation.
Subjects with either allergic asthma or allergic rhinitis will be recruited to obtain blood. This blood will be used to be stimulated with to whatever the patient allergic. In the laboratory, this stimulated blood will be measured for histamine, leukotrienes, IL-13 and IL-3. These are chemicals responsible for allergy symptoms.
This study will help to find out if having a certain genetic makeup influences how a person with asthma responds to salmeterol, one of the two drugs in Advair(R).
Trouble breathing (dyspnea) is a nonspecific symptom associated with many diseases such as chronic obstructive pulmonary disease (lung disorder in which the flow of air to the lungs is blocked), asthma, pneumonia, pulmonary hypertension (high blood pressure in the lungs), congestive heart failure (fluid build-up in the lungs because the heart is not pumping normally) and pulmonary embolism (blood clot in the lungs). The purpose of this study is to test two blood markers called ST2 and IL-33. Blood markers are proteins or other compounds in your blood that physicians use to diagnose different diseases and to determine what the course of an illness will be. In preliminary research studies, ST2 and IL-33 have been elevated in patients with a wide variety of diseases where the lungs are the primary organs involved. This research study will further investigate the ability of ST2 and IL-33 to predict the severity of disease and the possible use of ST2 and IL-33 in the diagnosis of various lung diseases.
This study is looking at the effects of certain long-acting bronchodilators on patients with asthma who have specific genetic variations. The investigators are interested in a certain common genetic variation in the receptor for beta-agonists, which is found in as many of one-sixth of the population. There is evidence that patients with asthma who have this variation may not do as well when treated with albuterol on a regular basis. The investigators will be looking at whether patients with this variation have more asthma exacerbations over the course of a year when treated with salmeterol or formoterol, which are long-acting forms of albuterol; and whether these patients have fewer exacerbations when treated with tiotropium, which is a different long-acting bronchodilator that does not act at this receptor. In both groups patients will also be receiving inhaled steroids.
The purpose of this research is to evaluate the methacholine challenge test as an accurate indicator of asthma in patients receiving treatment for asthma. Phase 1 on the study compares methacholine challenge test results from asthma patients to those from people who do not have asthma. In phase 2, test results for people with asthma on low dose inhaled corticosteroid will be compared to results on high dose inhaled corticosteroids. Both males and females with stable asthma (asthma participants) and without asthma (controls) enrolled. Participants will be between 12 and 69 years of age.
To compare the efficacy of SYMBICORT® pMDI 160/4.5 μg x 2 actuations twice daily (bid) to that of budesonide inhalation powder DPI 180 μg x 2 inhalations bid, in African American(self-reported) subjects with inhaled corticosteroid (ICS) dependent asthma.
The purpose of this study is to determine if a simple blood test can help in disease management, particularly asthma. This will be researched by looking at certain features of the blood and to compare asthmatics without allergies to those that have allergy-induced asthma.
A study to determine the efficacy of MK0476 in the Treatment of Asthmatic Patients Aged 2 to 5 Years.
The primary idea is that the use of a computerized reminder system to help with the guideline implementation will increase utilization and adherence of guideline-driven care, leading to improved patient outcomes. The hypothesis we aim to address is that an automatic, computerized reminder system for detecting asthma patients in the pediatric ED will increase paper-based guideline utilization compared to paper-based guideline without the system. We aim to implement a real-time, computerized asthma detection system and integrate the system with the pediatric emergency department information system, and evaluate the effect of the asthma detection system on reminding clinicians to use the paper-based asthma guideline.
