Filter by: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.
Exposure to airborne allergens and pollutants is linked to symptom severity of allergies, asthma and other respiratory problems. In this study an air purifier using photo-electrochemical oxidation technology (PECO) will be used in the home environment of study participants. The investigator will assess the reduction of symptoms from allergic rhinitis/conjunctivitis and asthma.
In this study, investigators evaluated for the first time the diagnostic efficacy of abioSCOPE® versus Phadia Laboratory System as an aid in the diagnosis of allergic diseases. Investigators targetted the agreement between test results obtained in abioSCOPE® and a laboratory reference method (Phadia Laboratory System, ThermoFisher Scientific, Uppsala, Sweden), considered as a quasi-gold standard in IgE (immunoglobulin E) antibody assays. Investigators also reported the medical decision taken by a panel of allergy experts who had access to patient history, skin tests and IgE antibody assay, but blinded to the method used, i,e, the reference method or the abioSCOPE® .
This study is a phase III clinical study to assess the efficacy and safety of Dymista® Nasal Spray in comparison to Azep® nasal spray and Flixonase® nasal spray in Chinese patients aged ≥ 12 years with moderate-to-severe allergic rhinitis/rhinoconjunctivitis.
The primary objective is to assess whether 16 weeks of treatment with dupilumab as an adjunct to Timothy Grass Subcutaneous Immunotherapy (SCIT) improves upon the efficacy of Timothy Grass SCIT to reduce provoked allergic rhinitis symptoms, as measured by Total Nasal Symptom Score (TNSS) after nasal allergen challenge (NAC) with Timothy Grass extract at week 17. The secondary objectives of the study are: - To assess whether 16 weeks of treatment with dupilumab as compared to placebo reduces provoked allergic rhinitis symptoms, as measured by TNSS after nasal allergen challenge (NAC) with Timothy Grass extract - To assess whether 16 weeks of treatment with dupilumab as compared to dupilumab + SCIT reduces provoked allergic rhinitis symptoms, as measured by TNSS after nasal allergen challenge (NAC) with Timothy Grass extract - To assess changes in serum Timothy-grass-specific immunoglobulin G4 (IgG4), serum Timothy grass-specific immunoglobulin E (IgE), and ratio of serum Timothy Grass-specific IgG4 to IgE over 16 weeks of treatment with dupilumab + SCIT as compared to SCIT monotherapy - To evaluate the safety and tolerability of 16 weeks of treatment with dupilumab as an adjunct to Timothy Grass SCIT
The goal of this study is to compare ten current and readily available FDA approved allergy skin prick devices to determine the most sensitive and specific product and methods used for the diagnosis of allergic disease. The primary outcome will be to determine the analytical sensitivity and specificity of all ten skin prick devices by measuring wheal and flare response to histamine and control diluent in 1mm increments. Secondary outcomes include comparison of skin prick technique, optimum histamine concentration, patient comfort, reproducibility, and the comparability of high-resolution digital images.
In this study subjects self recorded nasal and ocular symptoms scores from exposure to ragweed pollen in an Allergen Challenge Chamber (ACC). This single site study of seasonal allergic rhinitis was designed to enroll up to 35 participants. These participants would be age 18-70, male and female, with a mixture of ethnic groups. The study would involve 2 phases: Screening and Exposure. In the Exposure phase, participants were exposed to pollen for up to 180 minutes.
To assess the reproducibility of the allergic response in the cat allergic subjects, measured as the change from baseline of the Total Nasal Symptom Score (TNSS) on the two challenge days.
1. To compare the effectiveness of Benjakul extract capsules at 300 mg per day with Loratadine drug in the treatment of allergic rhinitis patients in small group (Clinical Trial Phase II). 2. To study the safety and side effects of Benjakul extract capsules 300 mg per day and Loratadine drug for allergic rhinitis patients.
The aim of the study is to assess the prevalence of bronchial hyperresponsiveness (BHR) in non-smoking adults with chronic cough and the prevalence of BHR in patients with upper airway cough syndrome (UACS) and gastroesophageal reflux disease (GERD), to evaluate the relationship between BHR and cough reflex sensitivity, to assess the diagnostic accuracy of methacholine challenge test (MCT) in cough variant asthma (CVA) with special regard to its discriminating cut off value between CVA and other causes of chronic cough, particularly GERD, to estimate prognostic value of BHR, fractional exhaled nitric oxide (FeNO) and induced sputum eosinophil count in predicting response to asthma treatment. Patients diagnosed with a chronic cough will undergo the standard diagnostic work-up recommended by experts for patients with a chronic cough, including methacholine challenge test (MCT) and an at least 4-week period of causal treatment. Patients with BHR in MCT will be treated with - in first step B2-agonist and inhaled corticosteroid (ICS) for at least 4 weeks, if improvement is not significant in next steps with leukotriene receptor antagonist (LTRA) or systemic corticosteroid. A good treatment response, evaluated by visual analogue scale (VAS), Leicester Cough Questionnaire (LCQ) and cough challenge will confirm the diagnosis of the disease. A statistical analysis will consist of the frequency of BHR in a chronic cough, correlation between the results of MCT and cough reflex sensitivity in capsaicin inhalation test and cut-off point for MCT to discriminate asthma from other causes of a chronic cough.
