Active clinical trials for "Rhinitis"

The purpose of this study is to evaluate the onset of action of fluticasone propionate nasal spray compared to placebo nasal spray in reducing nasal allergic signs and symptoms following ragweed exposure in the Allergen BioCube (ABC) after up to 14 days of at home dosing.

The degree of TH1-skewing by mycobacteria is controlles by NRAMP1 gene polymorphisms and related to the degree of inhibition of TH2-mediated disease.

Eye symptoms of tearing, redness and itching frequently occur in patients with allergic rhinitis or hayfever. The purpose of this trial is to study whether placing an allergen (a substance that causes allergies) directly in your nose can cause you to have eye symptoms as well as nasal symptoms.

This study seeks to compare patients with vasomotor rhinitis ("perennial nonallergic rhinitis," "idiopathic rhinitis") with normal controls with respect to their nasal physiologic reactivity to cold air challenge. Ten vasomotor rhinitis (VMR) patients with nasal symptoms triggered predominantly by cold air, four VMR patients with symptoms triggered predominantly by chemicals, and ten nonallergic, non-rhinitic control subjects will be studied.

Use of olopatadine ophthalmic solution (eye drops) will decrease allergy skin test reactivity.

Using a human pangenomic microarray, the researchers established expression profiles of nasal epithelial cells, collected by brushing of patients belonging to one of four distinct groups: allergic rhinitis to dust mite (AR) isolated (n=12), AR associated with bronchial hyperreactivity (n=12), AR associated with asthma (n=14), control (n=14).

This is a controlled clinical trials about traditional Chinese medicine named Qufeng Shengshi Fang，which consisted of cicada slough，bombyx batryticatus，radix angelicae，radix sileris，honeysuckle flower，forsythia，lithospermum and radix glycyrrhizae，and Loratadine on treatment of Allergic Rhinitis.There are 180 Patients with allergic rhinitis recruited from Department of Allergy and Traditional Chinese.To carry on statistical analysis of the result of the self and between-group cross-reference by two questionnaires filled before and after treatment.

The purpose of this study is to measure the amount of a nasal steroid spray (ciclesonide) absorbed by the tissue in the nose 2 hours after having this study drug sprayed in the nose

Objective biomarker of allergic rhinitis severity is necessary for monitoring disease severity and response to treatment in clinical setting and for research. We believe that psychological factors are the missing link between patient-perceived severity of allergic rhinitis and objective biomarkers. In our pilot study, several psychological factors were studied in relation to patient reported outcomes for severity of allergic rhinitis.

To compare the relative bioavailability and pharmacokinetic characteristics of a newly developed bepotastine formulation, bepotastine salicylate, with a conventional formulation, bepotastine besilate, in healthy subjects with a single dose, randomized, open-label, 2-sequence -2period crossover study.
