  • Title: [Food-dependent exercise-induced anaphylaxis that was difficult to evoke by a provocation test].
    Author: Inoue N, Yamamoto A, Matsumoto S, Ishigaki N.
    Journal: Arerugi; 2011 Nov; 60(11):1560-6. PubMed ID: 22270131.
    Abstract:
    As a result of ingesting wheat- and soybean-based food products in school meals, an 8-year-old boy repeatedly experienced dyspnea and urticaria while exercising. Based on the symptoms, he was assumed to have been experiencing a food-dependent exercise-induced anaphylactic reaction. Based on the Japanese pediatric guideline for oral food challenge in food allergy 2009, examination using various combinations of food products (wheat and soybeans), medicine (aspirin), and exercise was performed. However, the examination failed to elicit any symptoms. Although we eliminated the food products from the examination, dyspnea caused by exercising after ingesting only wheat products was observed again. Thereafter, we performed a provocation test using wheat products, but symptoms were observed only on increasing the amount of ingested food and the momentum of exercise, without administering aspirin. The possibility that wheat is a more potent inducing factor than aspirin in increasing the momentum of exercise and amount of ingestion in food-dependent exercise-induced anaphylaxis was suggested.
