Summary
Exercise-induced anaphylaxis can be fatal, even without typical allergy symptoms. This case highlights sudden cardiac death mimicking anaphylaxis after consuming nuts before exercise.
Area of Science:
- Allergy and Immunology
- Cardiology
- Forensic Pathology
Background:
- Exercise-induced anaphylaxis (EIA) is a rare condition triggered by physical activity.
- Food-precipitated EIA is an unusual variant, often presenting with atypical symptoms.
- Cardiovascular manifestations can be the sole presentation of EIA, potentially mimicking sudden cardiac death.
Observation:
- A sudden, unexpected death occurred in an individual post-ingestion of hazelnuts and almonds.
- The collapse happened during vigorous physical exertion (dancing).
- No typical anaphylaxis symptoms like skin rash or airway swelling were observed.
Findings:
- The death was attributed to anaphylaxis, despite no prior known nut allergy.
- Elevated serum tryptase levels indicated an allergic reaction.
- Allergen-specific IgE testing confirmed sensitivity to hazelnuts and almonds.
Implications:
- Highlights the critical need to recognize variable presentations of food-precipitated anaphylaxis.
- Emphasizes that EIA can present solely with cardiovascular symptoms, leading to misdiagnosis.
- Underscores the importance of considering anaphylaxis in unexplained sudden deaths during physical activity.
