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.

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.
To assess the separate and interactive effects of asthma severity, subspecialty practice variation, asthma-related psychosocial variables, and other factors on asthma outcomes, including a...
It is important for people with asthma to become involved in their asthma care and management. This study will evaluate an interactive Web site that provides tailored feedback and informat...

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...
WE HAVE PREVIOUSLY IDENTIFIED FOUR DISTINCT GROUPS OF ASTHMA PATIENTS IN KOREAN COHORTS USING CLUSTER ANALYSIS: (A) smoking asthma, (B) severe obstructive asthma, (C) early-onset atopic asthma, and (D...
Numerous studies involving patients with severe asthma have cited a relation between asthma and anxiety; this relation is responsible for decreased quality of life, increased morbidity, and higher hea...
Abstract Objective: The purpose of this study was to examine the incidence, characteristics of asthma morbidity and care, and ethnic differences that exist in older adults with asthma in California. M...
Asthma is a heterogeneous disease with variable characteristics such as lung function, symptoms and control, body weight, pattern of inflammation, and response to treatment. Brittle asthma is one of c...
