Summary
Food-dependent exercise-induced anaphylaxis (EIAn) diagnosis requires extensive allergy testing. Identifying specific food triggers and avoidance strategies effectively prevents EIAn episodes in most patients.
Area of Science:
- Allergology
- Immunology
- Clinical Medicine
Background:
- Food-dependent exercise-induced anaphylaxis (EIAn) presents diagnostic challenges.
- Identifying specific food allergens is crucial for effective management.
Purpose of the Study:
- To investigate diagnostic methods for food-dependent EIAn.
- To evaluate the efficacy of allergen avoidance in managing EIAn.
Main Methods:
- Allergy testing including skin prick tests (commercial and fresh foods) and specific IgE (CAP System FEIA RAST).
- Food-exercise challenges (FECs) and suspected food-exercise challenges (SFECs) were performed.
- Patients underwent comprehensive allergologic evaluation.
Main Results:
- 12 out of 14 patients showed hypersensitivity to multiple foods.
- Three patients were diagnosed with specific food-dependent EIAn (wheat, tomato).
- Dietary avoidance based on test results prevented further EIAn episodes in 12 patients.
Conclusions:
- Extensive allergologic testing, including fresh food testing and RAST, is vital for diagnosing food-dependent EIAn.
- Identifying and avoiding trigger foods is an effective strategy for preventing EIAn.
- Non-IgE mediated reactions also require dietary modification before exercise.
