Active clinical trials for "Food Hypersensitivity"

The purpose of this clinical study is to test whether patients with fish or shellfish allergy can ingest different types of fish oil supplements without having an allergic reaction. To achieve this, the recruited participants will be asked to: provide a blood sample (used for Basophil Histamine Release Assay) undergo a skin-prick-test partake in multiple oral provocations These three tests will indicate the likelihood that the participants can consume fish oil supplements without adverse allergic reactions (See the detailed description for an explanation of the tests). The investigators will test the participants tolerance for three different types fish oil supplements: Fish oil, Cod liver oil, and krill oil.

Positive reactions in atopy patch test in children with atopic dermatitis.

Assessment of the knowledge levels of restaurant personnel about food allergies. A structured questionnaire was given through a telephonic interview to evaluate the responses of the respondents.

The Nutrition Study of the GA2LEN Follow-Survey was designed to investigate the association between usual dietary intake and allergic and respiratory outcomes in adults across Europe. Within this framework, a food frequency questionnaire (FFQ) was designed to ascertain usual dietary intake of 250 food items, which was translated into the languages of the participant centres. Information on daily intake of foods, nutrients, and flavonoids was derived.

The purpose of this study is to attempt to understand how desensitization works in peanut allergic children who are undergoing oral immunotherapy (OIT) to peanut. We want to identify the early changes in the desensitization process the immune cells undergo to become desensitized to the peanut protein.

Food allergy reactions cause various health disorders in sensitive people. These reactions may be IgE-mediated,cell-mediated, energy disturbance-mediated, or a combination of the three. Certain laboratory diagnostic procedures have been able to identify most IgE-mediated or cell-mediated food reactions, but so far there is no test available in traditional medicine to test the energy-mediated allergies and sensitivities. NAET® procedures have been able to identify food substances triggering to energ disturbances in sensitive people causing related health disorders. NAET uses one of the testing procedures called NST (Neuromuscular sensitivity testing).The efficacy of NST-NAET to screen food sensitivity will be evaluated in comparison with one of the well accepted, established, traditional medicine allergy testing known as the IgE-specific antigen test.

The purpose of this study is to evaluate the clinical usefulness of assessing specific human allergy antibodies and other immunologic parameters associated with the diagnosis, evolution, and management of allergic disease.

The objectives of this study are (i) to evaluate the efficacy of oral immunotherapy to pistachio by evaluating the daily oral tolerance of 2g pistachio, by evaluating the long-term tolerance of 15g pistachio (sustained unresponsiveness) and by decreasing pistachio-specific IgE, (ii) evaluating the efficacy of pistachio immunotherapy on cashew tolerance, (iii) and to evaluate the safety of pistachio immunotherapy.

Food allergy affects up to 10% of the population. The mainstay of management involves dietary avoidance and provision of rescue medication in the event of an accidental reaction. The Integrated approaches to food allergen and allergy management (iFAAM) collaboration is an EU-funded academic/clinical/industry consortium with the aim to improve allergen risk management including food labelling. Much of this work requires the validation of the minimum 'eliciting dose' for the food-allergic population and how this can be translated into risk management. A number of studies (including iFAAM and the TRACE study - NCT01429896) have assessed the eliciting dose for peanut allergic patients, using food challenges where peanut-allergic individuals are eat incremental doses of peanut under strict medical supervision. In this extension study, peanut-allergic subjects will have undergone (in a cross-over manner) three double-blind, placebo-controlled food challenges to peanut: incremental doses of peanut in a water-continuous matrix; incremental doses of peanut baked into a cookie biscuit; a single dose of peanut in a water-continuous matrix. The differences in eliciting dose, symptom pattern and underlying physiological mechanisms will provide essential data on how the presentation and consumption of peanut affects the amount needed to trigger an allergic reaction, to inform industry and food regulators as to how to best protect the food-allergic population.

The purpose of the present study is to determine if asking adolescent patients (ages 13-17) to self-inject an empty syringe into their thigh during routine clinic visits results in increased reported comfort with self-injection, reduced anxiety regarding self-injection and food allergy management for both patient and caregiver(s), and in greater perceived likelihood of epinephrine self-injection, in the event of an emergency.
