Active clinical trials for "Rhinitis"

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.

App-based study of allergy patients under medication in the pollen season to determine the effect of allergic rhinitis on the quality of life.

Non-interventional study to investigate the safety and tolerability of allergy immunotherapy ACARIZAX® 12 SQ-HDM in real-life clinical practice in adults patients (>18 years) with house dust mite allergy over a period of 12 months.

Allergic rhinitis (AR) is triggered by environmental allergens such as pollen and mites, and is associated with several symptoms such as itching and nasal congestion, sneezing or tearing and redness of the eyes. RA can affect patients life quality who suffer it, reducing the quality of sleep and cognitive function, causing irritability and fatigue and, consequently a decrease in work performance. Because the existing pharmacological treatments for RA are not entirely effective, it is of interest to find other means to enhance the effects of these drugs and decrease more effectively the signs and symptoms associated with RA. In this context, RA has been related to an alteration of the intestinal microbiota (MI).However, there is a need to characterize in detail the MI of individuals who suffer RA. The main objective of the present study is to characterize the MI of individuals with RA, compared with people without RA. In addition, the secondary objective is to study the association between characteristics of the MI of individuals with RA and different immunological markers.

This was a multicenter, uncontrolled, open-label, special drug use study to investigate the safety and efficacy of Xolair by collecting data in its clinical setting in patients with severe to most severe seasonal allergic rhinitis aged ≥ 12 years and < 18 years whose symptoms were inadequately controlled despite to conventional therapies and used Xolair.

This study is a proof o concept aiming to determine the efficacy of Puressentiel nasal protective spray (PNPS) in patients with allergic rhinitis. Cross over study, with a nasal provocative test (NPT) in patients with allergic rhinitis sensitized to grass pollen. A day 0 (first NPT) the following outcomes are recorded: allergic Rhinitis control test (ARCT) and Inspiratory nasal peak flow (INPF) before and 30 min after the NPT. Nasal lavage is performed 30 min after the NPT and 3 cytokines (IL4, IL5 and IL13 are measured by ELISA. An other NPT is performed at day 30 and the same outcomes measured. 30 min before NPT 2 nasal sprays of PNPS are administered in each nostril in a randomized manner and cross over, the patient being is own control. The primary outcomes ins the IL4, IL5 and IL13 concentrations in the nasal lavage. ARCT and INPF are the secondary outcomes.

Evaluate the safety and general clinical response of desloratadine syrup in the relief of symptoms associated with perennial allergic rhinitis in Indonesian pediatric patients.

The objective of this non-interventional study is to evaluate the safety of Aerius syrup in pediatric patients aged 1-5 years old with allergic rhinitis or chronic idiopathic uticaria. The patients will receive 2.5 ml (1.25 mg) once daily.

To evaluate over a period of 6 months the safety and the treatment satisfaction of newly prescribed levocetirizine in patients of age ≥ 2 years with persistent allergic rhinitis.

In this study, researchers were primarily interested in evaluating the level of agreement of cooling sensation provided by this chewable, flavored, allergy medicine. Participants joining this study received one test drug tablet and were asked to chew completely before swallowing the drug. A questionnaire was used to collect the feedback from participants. The study involved only one (1) visit and participant stayed in this study for about 60-75 minutes to evaluate the cooling sensation as well as other sensory attributes perceived in the mouth, nose and throat.
