Active clinical trials for "Food Hypersensitivity"

To assess the frequency and nature of adverse events in infants fed a free amino acid based infant formula.

This study evaluates the addition of three probiotics (Bifidobacterium longum, Bifidobacterium breve and Bifidobacterium infantis) in the treatment of pediatric food allergic children to milk or egg. The allergic participants will receive the probiotics, while other two populations age and sex matched of not confirmed allergic and healthy children will not receive probiotics.

The purpose of this patient registry is to demonstrate safety and efficacy of food oral immunotherapy in food allergic patients. Factors that lead to adverse reactions will be identified. The frequency of rescue epinephrine use will be recorded.

The objective of this study is to examine how infant egg consumption (age of introduction and frequency of intake) influences physical growth, obesity, cardio-metabolic health, risk of food allergy, and cognition development in mid-childhood and adolescence.

Orality disorders are frequent in child. There are complications like growth and psychomotor development disorders. The aim is to estimate the prevalence of orality disorder for child with one or several food allergy.

Oral allergy syndrome is a type of food allergy which mainly affects people with springtime hay fever. It is caused by a cross-reaction, between antibodies to pollens, usually birch tree pollen, and allergens in many different plant foods. It is characterised by symptoms of itching and/or swelling in the mouth and/or throat when eating certain fruits vegetables and nuts. Many of the allergens causing OAS are destroyed by heat, making allergy testing using traditional allergen extracts unreliable. Prick testing or challenging with fresh foods is more reliable, but time consuming, inconvenient and largely unavailable. Pilot study results suggest the characteristic symptoms and foods involved in OAS allow accurate diagnosis using clinical history alone, which forms the basis for the hypothesis of this proposal that OAS can be diagnosed accurately by use of a validated questionnaire alone. The diagnostic questionnaire (PFSDQ), revised from the results of the pilot study, will be tested against two reference test methods, the gold standard of oral food challenge, and the 'platinum standard' of diagnosis made by a medical expert based on history, skin prick testing and oral food challenge. This is not an epidemiological study but with no published studies on OAS in a UK population, this study will also provide some information on the prevalence of OAS in those with springtime hayfever in the UK.

This study is aimed at verifying the role and the efficacy of the recombinants allergens Pru p 1, Pru p 3 and Pru p 4, Bet v 1, Bet v 2 and Bet v 4 in the diagnosis of peach allergy

To gain insights on the application, use and effectiveness of Frisolac Gold Intensive HA and Frisolac Gold PEP AC with reference to improvement of CMPA symptoms and to determine the methodology used by Mexican Health Care Professionals (HCPs) in the clinical practice (i.e. diagnosis and dietary management) of CMPA in Mexican children (≤24 months) diagnosed with or suspected of CMPA.

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.

Objective: This Phase II STTR grant incorporated user feedback collected in an earlier development project to build interactive, web-based software that helps children with food allergies learn about their condition and gain self-management skills. This highly interactive game allows children to progress through virtual scenes to help them learn about food avoidance, symptom detection, and reaction management. In addition, this project built gaming complexity, with more levels and game options, of the two interactive games "Label Learning: Like it or Lose it!" and "Reaction Action!".
