[Food-dependent exercise-induced anaphylaxis : a stepwise diagnosis]

Area of Science:

• Allergy and Immunology
• Gastroenterology

Background:

• Food-dependent exercise-induced anaphylaxis (FDEIA) is a severe allergic reaction triggered by food consumption followed by exercise.
• Cofactors like NSAIDs, alcohol, and infections can lower the threshold for FDEIA induction.
• Wheat omega-5 gliadin is a primary identified causative protein, but other foods and proteins are implicated.

Purpose of the Study:

• To evaluate the diagnostic efficacy of different cofactors and food challenges in diagnosing FDEIA.
• To compare the effectiveness of gluten flour versus wheat flour and NSAID+alcohol versus exercise in provocation tests.

Main Methods:

• The study involved oral food challenges, including allergen challenges, cofactor challenges, and integrated tests.
• Specific combinations tested included gluten flour, wheat flour, NSAID + alcohol, and physical exercise.

Main Results:

• Gluten flour and a combination of NSAID + alcohol were found to be more efficient in provocation tests.
• These combinations demonstrated greater efficacy compared to wheat flour and physical exercise, respectively.

Conclusions:

• The findings suggest that specific cofactor and food combinations can enhance the diagnostic accuracy of FDEIA testing.
• Optimized provocation test conditions may improve the clinical application and diagnosis of FDEIA.
