This study will test the effectiveness of an investigational treatment for patients with ragweed-induced asthma, sometimes called fall seasonal asthma. The treatment being tested is a series of anti-ragweed shots. The purpose of the study is to determine whether a short series of injections with Amb a 1-immunostimulatory oligodeoxyribonucleotide conjugate (AIC) can cause a long-lasting reduction in the symptoms of asthma that are caused by fall hay fever allergies.
Ozone can cause acute airway inflammation in both asthmatics and normal volunteers. However, in asthmatics ozone can cause episodes of worsening of asthma. We want to learn if chronic allergic response, known as "IgE-induced airway inflammation" is what causes the increased inflammation in response to ozone. To do this we will examine the response to ozone in a group of asthmatics treated with omalizumab, a medicine available and approved for use in people with asthma, or a placebo control. The placebo for this study is inert physiologic saline ("salt water") which contains no omalizumab. Both the omalizumab and the placebo will be administered as an injection under the skin. Omalizumab, also called Xolair, is a humanized monoclonal antibody, which means that it originally was produced in mice, then genetically engineered to look more like human than mouse antibody. Omalizumab inactivates IgE, a protein our own immune systems make as part of allergic reactions. The purpose of this study is to test the hypothesis that omalizumab, by blocking this aspect of allergic reactions, will decrease the number of inflammatory cells in the airway after ozone challenge. We also hypothesize that omalizumab will decrease the effects of ozone on changes in lung function, mucociliary clearance (a measure of how quickly mucus clears form the airway) and airway reactivity. Airway reactivity is a measure of how sensitive the airways are to a medication used to diagnose asthma, called methacholine. We will examine these as additional information we can learn during the course of the study. This is a blinded study, meaning that neither you nor the researchers know if you get the active drug or placebo, but that information can be obtained if needed. The placebo is an injection of inert physiological saline ("salt water") which contains no omalizumab.
The purpose of our study is to correlate nasal volume and cross-sectional area with nasalance scores. We will measure nasal volume and cross-sectional area with acoustic rhinometry. Nasalance scores will be determined by Nasometry. Acoustic rhinometry is a means to study the volume and cross-sectional areas of the nasal cavity in a non-invasive, rapid, convenient and reliable manner. Acoustic rhinometry has the unique advantage of being completely non-invasive, and thus is able to measure nasal patency without the confounding effects of probes or invasive monitoring. Nasometry is a technique to measure the oral and nasal components of nasalance. Nasalance is the objective measure of the nasal component of speech that is determined by the ratio of sound pressure emitted from the nasal and oral cavities during speech. Nasality is the term used to characterize the nasal component of speech, and is a subjective measure. Eleven healthy subjects underwent acoustic rhinometry pre and post decongestion using oxymetazoline 0.05% nasal spray. Nasalance scores were based on the readings of three passages: rainbow, zoo, and nasal.
Objective: Our overall objective is to test the hypothesis that the health of children with chronic respiratory symptoms or chronic exposures to environmental hazards can be improved through a combination of standard home maintenance interventions and a set of interim controls and targeted repair interventions. I. Background: The Bi-State Kansas City Enhanced Enterprise Community (KCEEC) is one of pervasive poverty, unemployment and general distress. This same area is also an area of poor environmental health with a disproportionate number of children with lead poisoning, asthma, and home injuries. In May 2001, the Metropolitan (Kansas City) Health Council released a report urging the implementation of strategies to address this growing concern. They stated, "Environmental assessments and interventions in homes, schools, and workplaces are needed to promote indoor air quality and thereby help prevent asthma and asthma flare-ups," in combination with the need for, "trained community-based peer educators needed to work with families/communities in areas of high asthma incidence,". The need for major rehabilitation is echoed in the 1999 Consolidated Plan, as well as by most community development and housing officials. The KC CERT project responds to these concerns by demonstrating low-cost, replicable intervention strategies that can have an impact on the health and safety of children and their families. By providing training and employment opportunities to residents in high-risk areas to assess, prevent and remediate environmental hazards, this project promotes sustained systematic change within the KCEEC.
The purpose of this study is to test and compare the allergenic effects of three commercially available German cockroach allergen extracts in adults. Study hypothesis: The biological potency of three commercially available German cockroach allergy extracts can be compared using the ID50EAL method to standardize German cockroach allergens.
This is a 38-week, randomized, double-blind, placebo-controlled, parallel group trial of approximately 150 patients who have a history of immediate hypersensitivity reaction to peanut protein.
