Asthma currently affects an estimated 15 million Americans. A number of studies have found an association between low dietary magnesium (Mg) intake and increased asthma incidence and severity of symptoms. However, clinical intervention trials are necessary to directly assess whether there is a true protective or preventative causal relationship between low Mg and asthma. In our study, we will assess the effects of 6 1/2 months of oral Mg supplements or placebo on clinical markers of asthma control, indirect biomarkers of inflammation, bronchial hyperresponsiveness, and indices of oxidative defense and damage in subjects with mild to moderate persistent asthma.
The purpose of the study is to evaluate an investigational medication to treat chronic persistent asthma. The research is being conducted at up to 22 clinical research sites in the US and is open to both men and women ages 18 to 70 years old. Participants in the study will have a number of visits to a research site over a 10-month period. All study-related care and medication is provided to qualified participants at no cost: this includes all visits, examinations and laboratory work.
The purpose of the study is to evaluate an investigational medication to treat chronic asthma. The research is being conducted at 20 clinical research sites in the US and is open to both men and women ages 18 to 70 years. Participants in the study will have a number of visits to a research site over an 8-month period. All study-related care and medication is provided to qualified participants at no cost. This includes all visits, examinations and laboratory work.
Controlled trial of an intervention to reduce indoor exposures to cockroach allergens among asthmatic children in NYC.
To examine the cellular and molecular mechanisms of corticosteroid and leukotriene receptor antagonists, focusing on their effects on T lymphocytes during both chronic (18 months) and acute therapy.
To identify genetic factors that influence the development of asthma in Hispanics.
In this project, we hypothesize that polymorphisms of genes expressed by the airway epithelia in asthmatics following specific airway challenges predispose individuals to the development of asthma. To test this hypothesis, we identify the genes that are differentially expressed by airway epithelial cells following challenge with stimuli that induce acquired (house dust mite) or innate (LPS) immune responses, and then determine whether polymorphisms in these genes are associated with the development of asthma in a separate, well characterized, familial cohort of asthmatics. This is a powerful approach that is designed to identify novel genes that are associated with both asthma pathogenesis (differentially expressed in the exposure-response study) and asthma susceptibility (genetically associated with asthma in a linkage/association study).
The purpose is to measure the effectiveness of recombinant human interleukin-4 receptor (IL-4R) in treating asthma. Asthma can be caused by the allergic response from breathing in certain irritants. Interleukin 4 (IL-4), which is naturally produced by the body, plays a major role in this allergic response. Doctors feel that IL-4 activity may be stopped by giving IL-4R, a product that binds to IL-4, and thereby decrease the problems of asthma.
To study work-related asthma in a low-income, urban population.
