Summary
Children with egg allergy can also develop allergic reactions to hen meat. This case highlights a rare IgE-mediated hypersensitivity to chicken meat, linked to egg protein sensitization.
Area of Science:
- Pediatric Allergy and Immunology
- Food Hypersensitivity Research
- Immunopathology of Food Allergies
Background:
- Egg allergy is a common childhood food allergy.
- Bird-egg syndrome, involving sensitization to bird proteins, is less frequent in children.
- This study investigates a rare case of hen meat allergy in a child with a history of egg hypersensitivity.
Observation:
- A child experienced angioedema after consuming hen meat.
- Skin prick tests showed positive reactions to egg yolk, alpha-livetin, and chicken meat.
- Specific IgE tests confirmed sensitivity to egg yolk and hen meat.
Findings:
- The patient exhibited IgE-mediated hypersensitivity to hen meat.
- Skin testing revealed sensitization to egg yolk and alpha-livetin, a pattern uncommon in pediatric cases.
- Prick-by-prick testing with hen meat was positive in the patient but negative in controls.
Implications:
- Hen meat allergy is an exceptional clinical manifestation.
- This case underscores the importance of considering hen meat as a potential allergen in children with egg allergy.
- Further research into cross-reactivity between egg and poultry proteins is warranted.
