Food-dependent, Exercise-induced Anaphylaxis: First Case Report in Thailand

Abstract

A forty-year-old military personnel presented with generalized urticaria, syncope, shortness of breath and headache associated with jogging after ingestion of a taro-filled bun and a red bean-filled bun. Skin prick test was positive for bread, taro and wheat but negative for red bean and preservative. Exercise challenge tests were performed. Exercise alone failed to induce any allergic reaction but exercise following ingestion of a taro­ filled bun and a red bean-filled bun induced generalized urticaria. Since the patient stopped taking these types of food, the urticaria has not returned. This is the first case report of food-dependent, exercise-induced anaphylaxis in Thailand.
