Summary
Wheat dependent-exercise-induced anaphylaxis (WDEIA) is a food allergy characterized by anaphylaxis elicited when wheat ingestion is time-related with physical exercise.
We report a case of WDEIA in an asthmatic boy admitted to our Unit with suspected mushroom acute toxicity. The symptoms occurred during a gym session, approximately 2 hours after the ingestion of a meal based on pasta and cooked mushroom found in the family's garden. Acute toxicity due to mushroom ingestion was then excluded. Triptase serum levels resulted elevated in acute phase and normal after 24 hours. Food specific IgE showed a sensitization to lipid transfer protein Pru p 3 and to Tri a 14.
This case highlights that WDEIA is underdiagnosed, especially when patients are firstly visited in Emergency Unit. Moreover, Tri a 14 is seldom described as responsible for WDEIA, compared to omega 5 gliadin.

Key words
wheat; food dependent exercise induced anaphylaxis; lipid transfer protein; wheat allergy; Ig-E mediated food allergy
