Active clinical trials for "Rhinitis, Allergic, Seasonal"

Dymista, a combined product containing the antihistamine azelastine and the intranasal steroid fluticasone, provides superior clinical efficacy to both fluticasone propionate and azelastine hydrochloride in the treatment of seasonal allergic rhinitis. The superiority of efficacy not only occurs at the initiation of treatment, but persists for its duration. The mechanism underlying the superior efficacy of Dymista is not known. This trial focuses on examining the effects of Dymista on the dynamics of the allergic response in man using nasal provocation with antigen. The investigators will study the relationship between symptoms, physiology, cells and mediators.

To evaluate the therapeutic equivalence of a test formulation of Azelastine hydrochloride and Fluticasone propionate Nasal Spray to the reference listed drug, Dymista™ Nasal Spray in the relief of the signs and symptoms of Seasonal Allergic Rhinitis.

Questionnaire to measure and control the quality of life of patients with hay fever who are treated or were treated with Pollinex quattro

An open access study that will define and collect digital measures of coughing in multiple populations and public spaces using various means of audio data collection.

The purpose of this study is to determine the proportion of participants that initiate allergen immunotherapy (AIT) upon the recommendation of their physician and the proportion of participants that persist with their AIT throughout the recommended course.

The primary endpoint was the induction of T-regulatory cells under s specific subcutaneous immunotherapy (SCIT). Patients suffering from grass pollen allergy (relevant clinical symptomes during the pollen season, Skin Prick test diamter >4mm or RAST class II or higher) were included. The patients were allocated to three study groups: Group 1: during and directly after SCIT (after completion the 2nd or 3rd year of treatment) Group 2: completed SCIT more then three years ago Group 3: Patients with clinically relevant grass pollen allergy without SCIT. The investigators analyzed the lung function parameters, exhaled NO (eNO) and asked the patients to record symptoms during the adjacent pollen season. A blood sample was drawn to analyze the amount of TH1 and TH2 and regulatory T-cells, inflammatory markers(IL-2, IL-5, IL-10, IL-12/23, TNF-alpha, IFN-gamma) and blocking antibodies (IgG, IgG4).

The purpose is to obtain real-world information on how consumers are complying with the product labelling This study will coincide with the launch of Pirinase Hayfever Relief for Adults 0.05% Nasal Spray in the United Kingdom (UK).

The purpose of this study is to analyze nasal samples for the presence of biomarkers of allergic inflammation as well as cold and flu infections, and compare these samples both in and out of an individual's active allergy season. 40 subjects who suffer from seasonal allergies will be recruited and seen both in and out of allergy season, and 10 healthy controls. Nasal epithelial lining fluid (NELF,) collected by placing small filter papers into the nostrils, blood for analysis and a cold/flu swab will be collected at each study visit.

Pollen allergic rhinitis is a very common condition whose symptomatic treatment is not always sufficient or satisfactory. The indication for allergic immunotherapy (IT) therefore often arises. The indication is based on the interrogation of the patient (chronology and severity of symptoms) and skin tests. But the interrogation, necessarily retrospective, brings often vague information and skin tests can be positive for allergens that have no clinical role (cross allergies). The objective of the project is to help the clinician in the indication of the IT, on the one hand by setting up a prospective and computerized collection of symptoms by a computer logbook accessible by the mobile phone of the patient. on the other hand by performing on the patient's serum a molecular diagnosis allow the identification of the major allergens to which the patient is sensitized. The same study will be conducted in 7 centers in southern European countries in patients aged 10 to 60 years with pollinosis. The examinations added by the research will take place during two routine visits: during a first visit, these patients will answer a standardized questionnaire, have a battery of allergological skin tests and a blood sample for molecular diagnosis. An application will then be loaded on their mobile phone and they will record their symptoms and medication during the pollen season. During a second visit, at the end of the pollen season, the allergist, in view of the data collected in the electronic notebook and the results of the molecular diagnosis will be able to prescribe a possible IT.

Inflammatory proteins from eosinophil granulocytes in blood from patients with seasonal allergic hayfever have been shown to predict development of asthma at a six-year follow-up. This study is a 15-year follow-up of the same patients to verify earlier results and study disease development.
