Filter by:About 45 million people in Europe have allergic rhinitis (hay fever) - inflammation of the nasal passages causing sneezing, runny nose, nasal congestion, itching and tearing of the eyes. In the United Kingdom (UK), seasonal hay fever due to grass pollen allergy accounts for approximately 7 times more doctors' appointments than asthma. The standard treatment for hay fever consists of treating the symptoms with a nasal spray and an antihistamine. However, in a survey taken in a UK general practice less than 40% of patients with hay fever reported good symptom control with this standard treatment. For those patients with hay fever whose symptoms are not well controlled by treatment with antihistamines and nasal sprays, subcutaneous immunotherapy (SCIT) - (monthly injections of a grass allergen extract for a period of 3-5 years) is an effective alternative, and is approved in the UK on a named patient basis. More recently, allergen immunotherapy tablets (AITs) have been developed, including grass pollen allergen tablets. These have been shown to be highly effective in the treatment of hay fever, with the additional benefit of being convenient for patients, given that they may be taken at home. Grazax® (manufactured by Allergologisk Laboratorium København (ALK)-Abello, Denmark) has UK and European Union (EU) license for use in the treatment of troublesome grass pollen induced hay fever. The aim of this research is to investigate the effects of the AIT treatment on the immune system over time - which changes are taking place and when in the course of treatment. This will provide insight into the complexities of the development of allergen-specific immune tolerance - how harmful allergic responses against innocuous substances such as grass pollen can be overridden.
Observation study of patients with chronic rhinitis or chronic urticaria in Thailand
Product information: Purotex is a textile treatment that uses five 100% natural bacteria or probiotics, selected for their ability to clean up house dust mite allergen along with other allergen types. Study design: - Placebo-controlled: the effect of the Purotex impregnated mattress and pillow covers will be compared to untreated, classical bedding covers (placebo). - Cross-over design: There will be 2 'treatment' arms. One arm (Arm 1) in which the subjects will first use the Purotex impregnated covers (Set A=Purotex) during 2 months (=period A) and, after a wash out period of 1 month, the untreated covers (set B=placebo) during 2 months (=period B). In the second arm (Arm 2), the subjects will first use the untreated set (set A=placebo) and, after a wash out period the Purotex impregnated covers (set B=Purotex). - Randomized: The subjects will be randomly assigned to one of the 2 treatment arms. - Double blind: both the subjects and the investigators will not know to which treatment arm the subjects are assigned. Study hypothesis: We want to investigate: - if there is a reduced concentration of HDM allergen in Purotex covers compared to untreated covers in real life - if patients with allergic rhinitis to house dust mite use the Purotex covers, they experience an improvement of their quality of life and sleep, and an improvement of their allergic symptoms and global discomfort
Chronic rhinosinusitis, a common diagnosis in children, remains a poorly understood disease. Adenoidectomy (surgery to take out the adenoid pads- infection fighting glands in the back of the throat) is performed since the adenoid pad may trap germs that enter a child's body and can get so swollen with bacteria that they become infected themselves. Functional endoscopic sinus surgery (FESS) and adenoidectomy are currently the most common surgeries performed on children with this disease. Another treatment is adenoidectomy and irrigation of the maxillary sinus without FESS. New technology has emerged using a balloon catheter to dilate (open) the sinus passage in addition to the adenoidectomy and irrigation. This study seeks to answer if children with chronic rhinosinusitis who undergo adenoidectomy with balloon dilation of the maxillary sinus passage and irrigation experience improved quality of life outcomes compared to children with chronic rhinosinusitis who undergo an adenoidectomy with maxillary sinus irrigation without dilation of the sinus passage.
This is a double-blind study with respect to the diluents used, with patients known to be allergic to the specific allergen tested. Three study sites will be involved, each testing one allergen (Cat, Mite, Timothy grass pollen). Subjects who are known to be allergic to the allergen in question will be tested with serial three-fold dilutions to determine the ID 50 and relative extract potency using the method described by Turkeltaub.
Allergic rhinitis is treated with a variety of systemic and locally applied drugs. The effectiveness of the intranasally applied formulations is diminished by the cleaning mechanisms of the nose, rhinorrhea in particular. Slowing down of the clearance of the nasal mucosa and prolonging the contact time of locally applied drugs with the nasal mucosa would improve their efficacy. One method is creating dosage forms containing mucoadhesive polymers. We have demonstrated that a mucoadhesive solution containing HPMC enhances the clinical efficacy of oxymetazoline. However, the industrial development of fixed combinations of pharmaceutical compound and mucoadhesive carrier requires substantial investments, escalating manifold if different pharmaceutical compounds have to be rendered mucoadhesive. NoAl is a cellulose derivative powder, which forms a gel layer on contact with the mucosal surface of the nose blocking the contact of the pollen grains with the nasal mucosa in seasonal allergic rhinitis. However, there is another potential benefit of applying NoAl (HPMC) along with other commercially available drugs for local treatment of rhinitis, as the formation of a gel layer can substantially delay their clearance from the nose and thus increase their effectiveness. This hypothesis needs to be substantiated clinically.
Allergic rhinitis might be caused by decreased resistance of nasal barrier to allergens and other environmental insults. About 20 % of the European population suffers from pollen allergies. Birch pollen allergic rhinitis is the most common allergic disease in the Scandinavia and it exists widely also in the Central Europe. Suffering and high costs of pollen allergies may be reduced by understanding the molecular biology of the nasal barriers during allergic response. Our aim is to observe the effect of season and birch pollen immunotherapy on the molecular biology of nasal epithelium and the microbiome.
This clinical validation study is aimed at establishing a birch pollen challenge in the Fraunhofer ECC in patients allergic to birch pollen. The symptoms will be recorded on a validated symptom score as Total Nasal Symptom Score (TNSS), allowing to determine whether the challenge is dose dependent and reproducible.
The purpose of this study is to evaluate treatment of perennial allergic rhinitis in Korean patients with AGR tablet.
