A Case of Squash-dependent Exercise-induced Anaphylaxis

Abstract

Food-dependent exercise-induced anaphylaxis (FDEIA) is a kind of exercise-induced anaphylaxis, which is characterized by anaphylactic symptoms only after eating certain foods. In Korean patients, wheat flour, apple, parsley, and crown daisy have been reported as causative foods. We report the case of an 18-year-old male with squash-dependent, exercise-induced anaphylaxis. The patient had urticaria, angioedema and chest discomfort during walking after taking roasted pork belly, green onion, lettuce, sesame leaf, mushroom and squash. He had also experienced the same event 4 months before this presentation. Skin prick test showed a strong positive reaction only to squash. Exercise provocation test turned out to be a negative result. However, exercise provocation test performed 30 minutes after ingestion of boiled squash resulted in hives with itching. Even though exercise provocation test performed just after ingestion of squash did not show any typical anaphylaxis reactions, this patient can be diagnosed with squash-dependent, exercise-induced anaphylaxis, based on his typical medical history and development of urticaria after the provocation test.
