Filter by:The purpose of the study is to evaluate changes in nasal airflow caused by loratadine 5 mg/pseudoephedrine sulfate 120 mg (Claritin D) tablet and fluticasone propionate 50 mcg per spray nasal spray (Flonase) in subjects suffering from nasal congestion and other allergy symptoms.
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.
This is an interventional, multicenter, double-blind, placebo-controlled trial in which patients diagnosed with non-allergic rhinitis will be randomized to either intranasal stimulation, or placebo treatment with the Chordate System at two occasions.
The study evaluates the safety and efficacy of intralymphatic allergen-specific immunotherapy given to adolescents and young adults who are allergic to grass or birch pollen and have mild or moderate asthma. Patients will be treated with three intralymphatic injections; 1000 SQ-U x3 with 4-5 weeks interval, or placebo with 4-5 weeks interval. The patients receiving treatment will be given a fourth injection one year after the initial injections. The study is conducted in collaboration between Professor Lars Olof Cardell (ENT), prof Gunilla Hedlin (Pediatrics) and prof Marianne van Hage (Immunology)".
To determine the effect of Montelukast in Asthma and Allergic rhinits patients
Co-phenylcaine is a widely available nasal spray commonly used by otorhinolaryngologists for the purpose of decongestion and local anesthetic prior to a nasoendoscopic or nasopharyngolaryngoscopy. It is often used in the outpatient setting and is also useful for minor procedures. It is unique in its properties because it provides both local anesthetic and decongestive effects on the nasal mucosa hence leading to better visualization of the nasal cavity and better comfort for the patient during the procedure. Pharmacologically, Co-phenylcaine Forte comprises of a combination of Lignocaine 5% (50mg/ml) and phenylephrine 0.5% (5mg/ml) and is commonly marketed in a 50ml bottle attached to a disposable positive displacement atomizer which avoids contamination by preventing contamination of the nozzle tip by secretions from other patients which are commonly seen in older venturi devices.Its decongestive agent (phenylephrine) acts by influencing the sympathetic vasculature tone via alpha adrenoceptors since its properties are sympathomimetic and oppose vasodilation.As for the local anesthethic component (Lignocaine) , it is an amide local anesthetic which blocks fast voltage gated sodium channels in the cell membrane thus leading to a decrease in sensation when performing a nasoendoscopy. Despite of its advantages, there are also disadvantages in the usage of such a device such as the need for regular change of the nozzle head due to the risk of infection and the high cost of using this device in the long run. Several studies has demonstrated promising results for the efficacy of nebulized medication and its distribution of medication into the nasal cavity and paranasal sinuses in both healthy individuals and cadaver models.Its advantages over the classical nasal spray include better distribution of medication throughout the nasal cavity and better hygiene due to the ability to change and sterilize the nasal nozzle tip before re-usage. Very little information is available about the delivery of topical decongestants via nasal nebulization on the pre-endoscopic examination of the nasal cavity. This study aims to compare the efficacy of topical decongestants delivered into the nasal cavity using nasal nebulization against the delivery of topical decongestants using conventional nasal sprays.
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 objective is to prospectively explore associations between immunological parameters in blood and clinical effect of subcutaneous immunotherapy (SCIT) in children with severe allergy towards pollen. Half of the children will receive SCIT while the other half will start SCIT after the study is finished. Clinical evaluations of symptoms and an immunological survey will be performed before start of SCIT and after one year of treatment. Some of the immunological parameters will also be checked after 6 months of treatment
The purpose of this study was to demonstrate the efficacy and safety of omalizumab compared with placebo, on top of SoC (anti-histamine and nasal corticosteroid) in adult and adolescent patients with severe Japanese cedar pollinosis, whose symptoms were inadequately controlled despite the current recommended therapies (nasal corticosteroids plus one or more medications out of anti-histamine, leukotriene receptor antagonist, or prostaglandin D2/thromboxane A2 receptor antagonist) in the previous 2 Japanese cedar pollen seasons.
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.
