Cohort Study of the Patterns of Microvesicles in the Serum of Participants With Atopic and Non-atopic 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 total of 20 participants (men or women) between the ages of 18-50 years with asthma will be enrolled. Participants will remain on their usual asthma treatments as prescribed by their usual asthma care provider. Current asthma treatments and any changes will be recorded at baseline and each subsequent visit. The primary outcome measures are correlation of microvesicle patterns with atopic state and variation from baseline with episodes of poor asthma control. Secondary outcomes include correlations between microvesicle patterns and spirometry, eNO levels, and glucorcorticoid sensitivity.

Some patients with mild asthma may develop severe asthma. It is not known what makes patients with mild asthma become severe, and we plan to find out why this happens. Patients with sever...
The purpose of this study is to identify the causes of asthma that were not previously suspected, to better understand the effects of inhaled steroids on asthma and to identify new way to ...
Smoking has detrimental effects on asthma symptom control and response to treatment and is prevalent among asthma patients in South Korea. The aim of this study is to determine the prevalence of smoki...
Obesity and asthma have increasingly been linked with an increased risk of developing asthma associated with increasing body mass index. Overweight/obese patients with asthma have more symptoms, poor ...
ABSTRACT The objective of this study was to estimate the prevalence of current asthma and the proportion of current asthma that is related to work on the farm among primary farm operators. The 2011 Fa...
Inhaled corticosteroids (ICS) are the cornerstone of asthma therapy. The ICS-to-total-asthma-medication ratios, calculated from claims data, indicate potentially risky disease management in asthma. Ou...
Childhood asthma and obesity have reached epidemic proportions worldwide, and the latter is also contributing to increasing rates of related metabolic disorders, such as diabetes. However, the relatio...
Medical and Biotech [MESH] Definitions
Asthma attacks following a period of exercise. Usually the induced attack is short-lived and regresses spontaneously. The magnitude of postexertional airway obstruction is strongly influenced by the environment in which exercise is performed (i.e. inhalation of cold air during physical exertion markedly augments the severity of the airway obstruction; conversely, warm humid air blunts or abolishes it).
Drugs that are used to treat asthma.
A beta-adrenergic agonist used in the treatment of asthma and bronchospasms.
An adrenergic beta-agonist used as a bronchodilator agent in asthma therapy.
Adrenergic beta-2 agonist used as bronchodilator for emphysema, bronchitis and asthma.
