Filter by:This is a study for children and adults who are interested in a new therapy for their allergies to dust mite and timothy grass. The new therapy is called sublingual immunotherapy and the investigators are testing if it is safe and well tolerated.
The purpose of this study is to evaluate the non-inferiority clinical efficacy of two different drug associations in the treatment of Moderate - Severe Persistent Allergic Rhinitis.
Hay fever (seasonal allergic rhinitis) results from allergy to grass and tree pollen. The majority of affected individuals manage well with medication from the Pharmacy or from their general practitioner (GP), but for some severely affected people it severely impacts on quality of life. Less than 40% of those affected in UK general practice feel that these medications achieve good symptomatic control. Specific immunotherapy or desensitisation is the practice of administering small amounts of allergen to allergic patients in increasing doses. This treatment is highly effective in these patients and furthermore is truly disease-modifying, with benefits persisting long-term, even when the treatment has been completed. Desensitisation is a routine treatment in the UK, Europe and North America. The exact immune mechanisms that underlie this symptomatic improvement are not entirely clear. Dr Tarzi, Professor Frew and Professor Kern have recently developed new methods for the investigation of immune responses to allergens. These methods require relatively small blood samples and may provide useful information about how immunotherapy exerts its effects. In addition to improving the investigators basic understanding of this treatment, such knowledge may drive improvements in the treatment and could be useful for monitoring patients for response. The investigators study proposes to investigate changes in the immune responses to pollen allergens during immunotherapy. Blood will be taken just prior to the first immunotherapy injection and again just prior to the final injection. In this way the investigators will be able to compare the immune responses to pollen allergen before and after treatment.
The primary objective of this study is to determine if broccoli sprouts (BS) improves nasal inflammatory, oxidative stress (OS), and symptom responses to nasal mouse allergen challenge (NAC) in mouse-sensitized adults perennial allergic rhinitis. The study is a double-blind, placebo-controlled, randomized trial to compare BS to placebo in 24 mouse-sensitized adults with asthma or perennial rhinitis and who develop rhinitis symptoms with nasal mouse allergen challenge. Twenty-four adults (age 18-50) who meet these eligibility criteria will be randomized to receive either: (a) BS or (b) placebo. At the baseline NAC, FENO, FEV1, nasal epithelial gene expression, urinary OS biomarkers, serum inflammatory and OS biomarkers, basophil activation, and symptoms will be assessed both before and after NAC to establish pre-intervention responses to NAC. Subjects will eat a sprouts sandwich daily for three days, and then undergo repeat NAC that includes measurement of the above outcomes both before and after NAC.
The purpose of this study is to evaluate the clinical efficacy and mucosal/systemic antibody response changes after SLIT using house dust mite allergen with or without bacterial extracts in mite-allergic children.
The purpose of this study is to evaluate safety and efficacy of Nasya in reducing symptoms of persistent allergic rhinitis when applied before allergen challenge.
The purpose of this study is to analyze the expression and activity of inhibitory molecules on eosinophils obtained from allergic subjects.
The diagnosis of allergic rhinitis to dust mites is difficult and based on three elements : suggestive symptoms of clinical sensitization to dust mites (rhinitis), the existence of an IgE sensitization defined by skin tests and / or specific IgE positive to mite and finally the presence of mite allergens in the environment where the patient is symptomatic. Unfortunately, the link between symptoms and exposure to dust mites is rarely found and according to in the literature, 30% of rhinitis sensitized to house dust mites did not react during a conventional nasal provocation test (TPNC) to dust mites. Thus, TPNC to dust mite has an interest in the diagnosis of allergic rhinitis to dust mites when there remains a doubt due to the poly sensitization of the patient, or the lack of specific symptoms and / or the variability of the allergic symptoms during the year. However, this test has not been completely validated with a study including a significant number of patients. That's why the investigators plan a prospective single-center comparative open study with the main objective is to determine the sensitivity and specificity of conventional nasal provocation test (TPNC) in 120 patients of 18 to 65 years old with allergic rhinitis sensitized to dust mites and patients with allergic rhinitis not sensitized to dust mites. The investigators secondary objective is to compare the TPNC a faster TPN-called "minute" (60 minutes) and which allow a wider use. If the investigators demonstrate the validity of TPN then it would become the gold standard needed to decide on a desensitisation to mites.
Study design: Randomized, controlled, double-blind, parallel, multicentre multinational clinical trial, to show superiority of an active therapy as compared to a control therapy on intermittent or persistent Allergic Rhinitis. Primary objective: 1. To show that a topical microemulsion is superior to a sterilized saline solution to prevent deterioration in the health related quality of life, in patients with intermittent or persistent allergic rhinitis due to sensitization to birch, olive tree or grass pollen. Secondary objectives 2. To explore the effect of a topical microemulsion, as compared to a sterilized saline solution, for the prevention of nasal and ocular symptoms in patients with intermittent or persistent allergic rhinitis due to sensitization to birch, olive tree or grass pollen. 3. To explore the effect of a topical microemulsion, as compared to a sterilized saline solution, in the utilization of symptomatic medications, in patients with intermittent or persistent allergic rhinitis due to sensitization to birch, olive tree or grass pollen. 4. To assess the patient's satisfaction with a topical microemulsion treatment, as compared to a sterilized saline solution, in patients with intermittent or persistent allergic rhinitis due to sensitization to birch, olive tree or grass pollen. 5. To assess the safety of a topical microemulsion, as compared to a sterilized saline solution, administered to patients with intermittent or persistent allergic rhinitis due to sensitization to birch, olive tree or grass pollen. This is a clinical investigation study of a Class 1 medical device product. This is a prospective study of an active medical device versus a control medical device. It was considered feasible to recruit 10 patients patients per center, and therefore the study should be conducted in 10 centers. To get treatment balance within each center, a total of 100 patients should be recruited.
The primary objective of this study is to assess the relative efficacy of Ectoin® Allergy Eye Drops and Ectoine® Allergy Nasal Spray compared to placebo, by evaluating Total Nasal Symptom Score (TNSS) and Total Ocular Symptom Score (TOSS). The secondary objectives are : - To evaluate the relative efficacy of Ectoin® Allergy Eye Drops and Ectoin® Allergy Nasal Spray compared to placebo by evaluating Total Non Nasal Symptom Score (TNNSS), congestion symptom scores, red eye symptom scores, watery eye symptom scores, itchy eye symptom scores, and by evaluating the mean cross-sectional area (MCA) using acoustic rhinometry (AcR). - To assess the change from baseline (post-EEC from pre-EEC) in inflammatory parameters of nasal secretions, comparing Ectoin® Allergy Eye Drops and Ectoin® Allergy Nasal Spray to placebo at each post-treatment visit.
