Filter by:The specific aim of this proposed project is to implement a standard process for integrating MedlinePlus health information prescriptions into the clinic workflow. Hypothesis 1: Individuals in the intervention group who receive tailored email health information with provider selected MedlinePlus links and added commentary for patient specific conditions will be more likely to seek information / use MedlinePlus compared with individuals in the control group. Hypothesis 2: Individuals in the intervention group who receive tailored email health information with provider selected MedlinePlus links and added commentary for patient specific conditions will be more satisfied with the information received compared with individuals in the control group.
Cysteinyl leukotrienes (CysLTs) play an important role in asthma. CysLTs exert most of their bronchoconstrictive and pro-inflammatory effects through activation of the CysLT1-r. As allergic rhinitis appears to be a predisposing factor in the development of asthma and as CysLT-receptors seem to be implicated in the first steps of asthma manifestations, we think it would be of interest to determine if the CysLT1-r is a key mediator in the progression from allergic rhinitis to asthma. We believe it would be interesting to study the expression of the CysLT1-r Our goal is to assess baseline, as well as variations following allergen bronchoprovocations, in the expression of the CysLT1-r in mild asthmatic subjects compared with non asthmatic subjects with allergic rhinitis. Our hypothesis is that there will be a higher baseline expression of the CysLT1-r in asthmatic subjects compared with allergic rhinitis subjects and that allergen bronchoprovocations will induce an increase in the expression of the CysLT1-r in both groups.
To determine the safety of levocetirizine in children ages 6-11 months with symptoms of allergic rhinitis or chronic idiopathic urticaria.
This study will evaluate the safety and tolerability of single and multiple doses of VAK694 in healthy volunteers and otherwise healthy volunteers with a history of allergies.
The purpose of this study is to determine the safety of the oral formulation of levocetirizine in children ages 1 to less than 6 years old who suffer from allergic rhinitis or chronic urticaria of unknown origin.
The purpose of this study is to better understand the way in which CO2 (carbon dioxide) affects the symptoms of allergic rhinitis or hayfever. Our intent is to determine if CO2 has an effect on nasal challenge with antigen as a predictor of whether it will have a beneficial effect on the treatment of seasonal allergic rhinitis.
Allergic rhinitis (AR) is a condition that exists when an individual with a specific allergy reacts to that allergen resulting in a runny and/or stuffy nose, postnasal drip, and possible symptoms of sneezing, scratchy throat, itchy nose, ears or throat. When the allergic person is exposed to such an allergen, the body reacts with overproduction of certain chemicals which cause inflammation and subsequent symptoms of AR. These responses are related to the body's hyperreactive response to exposure to an otherwise harmless substance such as dust, ragweed, pollen, cat dander etc. There are data to suggest that air pollution resulting from diesel exhaust can increase the body's response to airway inflammation caused by virus. The purpose of this research study is to determine if individuals with AR have increased inflammatory responses to flu virus following exposure to diesel exhaust (DE) vs exposure to clean air compared to how individuals who do not have allergies respond to the same exposure conditions. The hypothesis for this study is that diesel exhaust exacerbates LAIV-induced allergic nasal inflammation, using controlled exposures in AR volunteers compared to non-allergic individuals
This study is an 8 day, randomised, double blind, 2-way crossover trial of repeat doses of intranasal GSK256066 and azelastine hydrochloride in the Vienna Challenge Chamber in subjects with seasonal allergic rhinitis (SAR). Laboratory safety assessments, 12-lead electrocardiograph (ECG), vital signs and adverse event enquiries will be made throughout the study. Nasal examination, symptom scores, and allergen challenge assessments will also be performed at various time points throughout the study.
This research is being done to study the effects of the drug omalizumab (Xolair) in people with cat allergies. The investigators will use omalizumab to study changes in the cells in the nose, skin and blood that cause allergies. The investigators predict that cells in the blood will be effected before cells in the nose or skin.
The purpose of this study is to evaluate the clinical effectiveness, safety and pharmacokinetics of JNJ-17166864 in patients with seasonal allergic rhinitis.
