Introduction:
Exercise induced-anaphylaxis is a rare allergic disease. In most cases, the ingestion of a specific food within a maximum of 4 hours preceding physical activity is necessary to develop the anaphylactic reaction.
Case-Reports:
We report 7 cases of food-dependant exercise induced-anaphylaxis. The responsible foods were wheat (2 cases), corn, barley, shrimp, apple, paprika and mustard. The discovery of the food allergen and its systematic eviction 4 hours before the beginning of a physical effort led to the disappearance of clinical symptoms in all cases.
Discussion:
The role of food in exercise-induced-anaphylaxis is essential. The food in cause varies but our study confirms the predominant role of cereal food which is a less sensitizer in adults, except in a context of effort. The responsibility of this type of food consumed daily can explain partially the frequent delay before diagnosis of this allergic disease.
