Egg introduction during complementary feeding according to allergic risk: not just for peanuts!

Area of Science:

• Pediatric Allergy and Immunology
• Gastroenterology
• Immunology

Background:

• Current guidelines suggest introducing complementary foods, including potential allergens, after 4 months of age.
• The European Society for Pediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) supports early introduction of allergenic foods.
• Specific guidance is needed for infants at high risk of developing food allergies.

Discussion:

• The timing of complementary food introduction is crucial for allergy development.
• Early introduction of allergenic foods may play a role in immune tolerance.
• Individualized approaches are necessary, especially for high-risk populations.

Key Insights:

• For infants at high risk of food allergy, specific precautions regarding egg introduction are advised.
• Pre-introduction assessment for egg allergy, including IgE serum antibody levels or skin prick tests, is recommended.
• Adequate topical therapy should be considered before the first egg feeding in high-risk infants.

Outlook:

• Further research is needed to refine recommendations for early allergen introduction in high-risk infants.
• Developing personalized strategies for food allergy prevention is a key future direction.
• Long-term studies will help elucidate the precise impact of early allergen exposure on allergy development.
