Food allergy and anaphylaxis – 2065. Food-dependent exercise-induced anaphylaxis in a patient with sensitization to pork
نویسندگان
چکیده
Methods A 15-year-old female presented with generalised urticaria, dyspnea, severe cough, headache, dizziness, and vomiting after singing and dancing for 1 hour and after ingesting grilled pork. Serum specific IgE and skin prick tests were performed. Oral food challenge with boiled pork meat were done. We started boiled pork meat 10g to 160g every 30 mimutes. Exercise provocation test before and after pork ingestion were done.We did IgE immunoblotting with patient’s serum by cooked (grilled, boiled) and raw pork allergen.

Wheat-dependent, Exercise-induced Anaphylaxis: A Successful Case of Prevention with Ketotifen.
Food-dependent, exercise-induced anaphylaxis (FDEIA) is the triggering of anaphylaxis after ingestion of certain foods when followed by physical exercise. Symptoms vary from the typical generalized urticaria to severe allergic reactions. We report the case of a 20-year-old woman who had a 7-year history of recurrent wheals and dyspnea after ingesting several kinds of food (wheat, pork, and beef...

Food Dependent Exercise-Induced Allergy is a rare condition. However, the occurrence of anaphylaxis is increasing especially in young people. The diagnosis of anaphylaxis is based on clinical criteria and can be supported by laboratory tests such as serum tryptase and positive skin test results for specific IgE to potential triggering allergens. Anaphylaxis prevention needs strict avoidance of ...

BACKGROUND Challenge tests for food-dependent exercise-induced anaphylaxis (FDEIA) carry some risk and have a high rate of false negatives. Our aim was to explore the usefulness of an in vitro immunodepletion assay and an allergen microarray test in the identification of IgE-mediated cross-reactive food allergens in patients with suspected FDEIA or food-dependent exercise-induced urticaria and ...
متن کاملThe roles of basophils, TSLP and IL-33 in food allergy following epicutaneous sensitisation
Cutaneous sensitization with a food antigen before its consumption elicits the development of food allergy. Here we report the site and stage dependent roles of basophils and pro-allergic cytokines, thymic stromal lymphopoietin (TSLP) and IL-33, in a mouse model of food allergy initially sensitized cutaneously with the food antigen. Mice are epicutaneously sensitized with the food antigen ovalb...
