Filter by:The purpose of this study is to assess the effect on various biomarkers of treatment with MK-8237 in participants with allergic rhinitis or rhinoconjunctivitis. In Part 1 of the study healthy participants undergo nasal allergen challenge (NAC) with house dust mite (HDM) extract in order to verify the operational performance of NAC and associated sample collection methods. Part 2, the main study, is a placebo controlled, double blind study of participants with HDM-induced allergic rhinitis or rhinoconjunctivitis. The primary hypotheses are that the changes from baseline in post-allergen challenge HDM-specific Immunoglobulin G4 (IgG4) and Immunoglobulin E blocking factor (IgE-BF) are greater after treatment with MK-8237 than after treatment with placebo.
The researchers investigated the relationship between migraine and allergy. For this purpose, the researchers designed a controlled study to evaluate nasal symptoms and signs; and to perform Specific Immunoglobulin E (IgE) measurements in migraine patients and healthy subjects. According to these results the prevalence of allergic rhinitis in migraine group was planned to be compared to that of the healthy controls, statistically.
The purpose of this study is to prospectively examine the relation between topical corticosteroid use and hair cortisol concentration, among patients with moderate persistent asthma or allergic rhinitis. The investigators hypothesize that patients with asthma or allergic rhinitis treated with topical corticosteroids (i.e. inhaled corticosteroids (ICS) or intranasal glucocorticoids (INGC)) have higher levels of hair cortisol after 3 months of treatment than during the 3 months prior to initiation of treatment.
The objective of this study is to determine the biologic activity of a Dermatophagoides pteronyssinus allergen extract in histamine equivalent prick (HEP) units, in order to be used as in-house reference preparation (IHRP).
This study is designed to investigate the efficacy of fluticasone propionate (FP) on ocular symptoms associated with allergic rhinitis (AR).
The aim of this study is to assess the influence of kind of allergic disease, allergic profile, allergen exposure, treatment method on lung function parameters, fractional exhaled nitric oxide level in children suspected and being diagnosed due to allergic diseases.
This study will assess the safety and efficacy of QAW039 alone and in combination with Montelukast in patients with allergic rhinitis (hay fever) using an environmental exposure chamber.
This is a 3 month safety study of Dymista Nasal spray in children aged 4 to 11 years with allergic rhinitis
The purpose of this study is to evaluate the efficacy and safety of Beclomethasone dipropionate (BDP) nasal aerosol in subjects with Perennial Allergic Rhinitis (PAR).
Primary Objective : To compare the acute bronchodilatory effects of cetirizine 10 mg tablet and nebulized levalbuterol using impulse oscillometry technique in asthmatic subjects aged 18 to 65 years old who have allergic rhinitis and show clinical evidence of bronchial hyper-reactivity. Secondary Objective: To assess the bronchodilatory effects of cetirizine 10 mg tablet versus placebo after two weeks of therapy using impulse oscillometry technique in subjects 18 to 65 years old who have allergic rhinitis and show clinical evidence of bronchial hyper-reactivity.
