Summary
Two patients experienced anaphylaxis triggered by exercise after consuming apples. This highlights the importance of identifying specific food triggers in food-dependent exercise-induced anaphylaxis.
Area of Science:
- Allergy and Immunology
- Clinical Medicine
Background:
- Exercise-induced anaphylaxis (EIA) is often linked to food ingestion, termed food-dependent EIA.
- Identifying specific food triggers can be challenging in diagnosing EIA.
Observation:
- Two cases of apple-dependent exercise-induced anaphylaxis are presented.
- Diagnostic methods included skin prick tests, specific IgE determination (CAP-Pharmacia System), and exercise challenge tests after apple consumption.
Findings:
- Prick-by-prick testing with fresh apple was positive in both patients.
- Specific IgE levels for apple were elevated.
- Exercise challenge tests successfully reproduced anaphylactic episodes under specific conditions.
Implications:
- This case series underscores the significance of apple as a potential trigger for food-dependent EIA.
- Accurate diagnosis requires a comprehensive approach including specific food challenges.
- Awareness of less common food triggers is crucial for effective patient management.
