Food allergen ladders: A need for standardization.

Area of Science:

• Allergy and Immunology
• Clinical Nutrition
• Pediatric Gastroenterology

Background:

• Food allergen ladders are used for the gradual reintroduction of allergenic foods into a patient's diet.
• Questions remain regarding optimal food selection, ladder structure, and safety protocols.
• The rise of telehealth necessitates standardized approaches for online allergen introduction.

Purpose of the Study:

• To review current food allergen ladders.
• To summarize existing knowledge and clinical expertise on food allergen ladders.
• To propose standardized approaches for developing and implementing food allergen ladders.

Main Methods:

• Conducted a literature search for published food allergen ladders.
• Synthesized information from published data and clinical expertise.
• Identified key considerations for developing standardized food allergen ladders.

Main Results:

• Limited published ladders exist for common allergens like milk, egg, wheat, and soy.
• Key considerations for ladder development include allergen properties (dose, temperature), nutritional factors (value, taste), and medical aspects (patient safety, rescue medication).
• Standardized written instructions and recipes are recommended for families.

Conclusions:

• Food allergen ladders are increasingly used globally for allergen reintroduction.
• Standardization of food components and medical safety guidelines is essential for patient-centered care and safety.
• Further research and consensus are needed to establish universally accepted food allergen ladder protocols.
