Leukotrienes play critical roles in the inflammatory process in allergic rhinitis and bronchial asthma, therefore, anti-leukotriene therapy is part of treatment for asthma. However, not all allergic rhinitis accompanied with or without asthma treated with anti-leukotriene were effective. So it is critical to develop a method to identify the response subgroup. In this study, it is assumed that nasal physiological responsiveness to leukotriene nasal provocation test (NPT) is able to gain evidence on the effect of leukotriene on the development of allergic rhinitis and asthma, and is helpful to the use of anti-leukotriene agent. The purpose of the study is to establish the methodology and diagnostic value of leukotriene D4 (LTD4) nasal provocation.
Allergic rhinitis (allergic inflammation of the nose) is a common medical condition which is known to seriously decrease quality of life, aggravate preexisting conditions particularly asthma, carry significant medical treatment costs and be responsible for reduced work productivity and lost school days. A significant symptom of the condition, nasal blockage, remains difficult to treat even when using nasal corticosteroids. Decongestant medications act on the blood vessels in the nose and have an immediate effect in clearing a blocked nose but if used for more than seven days a more severe rebound congestion of the nose develops. In this study, the investigators aim to assess the effects of doxazosin, a drug which is currently used to treat high blood pressure and symptoms of prostate enlargement, to find out if it has an effect on nasal blockage.
A Multi-Center Study Evaluating the Nasal Allergic Symptomatology Induced by a Nasal Allergen Challenge (NAC) in a Dust Mite Population
This study investigates the safety of two up-dosing regimen. The safety of PURETHAL Birch will be evaluated in a rush regimen (maximum dose reached in 3 injections during 3 weeks) compared to the conventional regimen (maximum dose reached in 6 injections during 6 weeks). The primary endpoint of the sudy is the comparison of the proportions of the patients who have successfully reached the maintenance dose between the two treatment regimes. A similar previous study with PURETHAL Grasses has shown that the rush up-dosing scheme is as safe as the conventional up-dosing regime. Therefore it is expected that up-dosing with PURETHAL Birch according to the rush regimen is as safe as using the conventional regimen.
Our central hypothesis is that dietary limitations introduced by food allergy will contribute to increased food insecurity in households with food allergic children when compared to food insecure households without food allergic children.
To compare the relative bioavailability and pharmacokinetic characteristics of a newly developed bepotastine formulation, bepotastine salicylate, with a conventional formulation, bepotastine besilate, in healthy subjects with a single dose, randomized, open-label, 2-sequence -2period crossover study.
The purpose of this study is to compare the safety of 2 different doses of the investigational use of an allergy medication (Astepro Nasal Spray) in the treatment of allergic rhinitis (AR). This is an open-label study; that is, parent and child will know which group each is in.
Subcutaneous allergen immunotherapy (SCIT) is a widely used and effective treatment modality for allergic rhinoconjunctivitis and asthma. SCIT starts with a build-up phase during which a patient receives frequent, escalating doses of the allergens they are allergic to until they reach a predetermined maintenance dose. This is followed by a maintenance phase during which the allergen dose is kept constant and administered at greater intervals. Maximum clinical improvement is generally not seen until a patient is in the maintenance phase. Anecdotal evidence of possible reactions to SCIT administered during a patient's pollen season has led to dosage freezes during a patient's pollen season which extends the length of the build-up phase by many months. Prolonging the buildup phase increases the time required to obtain maximal benefit from SCIT, and at the same time, can decrease patient compliance with therapy due to the prolonged period of time when frequent injections are required. The aims of this study are to determine if adverse reactions to pollen SCIT are increased if doses are increased during pollen season.
The purpose of the study is to investigate the effectiveness and cost-effectiveness of the integrated care program of a statutory health insurance offering additional homeopathic treatment to their members
