Food-dependent exercise-induced anaphylaxis to chickpea in a 17-year-old female: a case report

INTRODUCTION Food-dependent exercise-induced anaphylaxis is a subtype of anaphylaxis and, although rare, it is an important condition to be familiar with as it can ultimately lead to death. CASE PRESENTATION We present a case of food-dependent exercise-induced anaphylaxis in a 17-year-old white girl due to chickpea. She had a history of anaphylaxis after eating crackers and hummus before exercising. Skin prick testing and serum-specific immunoglobulin E level confirmed chickpea to be the causative allergen. CONCLUSIONS This case demonstrates the challenge in identifying specific causative food allergens when foods are eaten in combination, when the food is processed, and when cross-reactivity is possible. These challenges add complexity to a condition that is already rare and unfamiliar to some health care providers. We hope that this case will serve as an important reminder that although rare, food-dependent exercise-induced anaphylaxis exists and making a diagnosis can lead to life-saving preventative strategies. As legumes are not a common food associated with food-dependent exercise-induced anaphylaxis, this will add to our current knowledge base in the field of allergy.
