Egg desensitization is achieved effectively and safely through a low maintenance dose protocol.

Area of Science:

• Allergy and Immunology
• Pediatric Medicine
• Food Science

Background:

• Egg allergy is a prevalent IgE-mediated food allergy in children.
• Oral immunotherapy (OIT) involves gradual allergen exposure to reduce allergic reactions.
• High-dose OIT carries risks; evidence for low-dose egg OIT (E-OIT) is limited.

Purpose of the Study:

• To evaluate the safety and effectiveness of a low dose (300 mg) of E-OIT for inducing desensitization in children with egg allergy.

Main Methods:

• Twenty children were randomized into immediate-treatment or observation groups.
• Assessed cumulative tolerated dose (CTD), specific IgE (sIgE), specific IgG4 (sIgG4), and skin prick test responses.
• Monitored adverse events throughout the study.

Main Results:

• E-OIT significantly increased CTD from a median of 14.1 mg to 6000 mg.
• Adverse reactions were infrequent (15.6% of doses) and mostly mild.
• Skin prick test wheal diameters decreased, while sIgG4 levels increased and sIgE levels declined.

Conclusions:

• A low maintenance dose of 300 mg E-OIT is safe and effective for treating egg allergy.
• This approach induces significant clinical and immunological changes.
• Low-dose E-OIT offers a favorable risk-benefit profile for pediatric egg allergy management.
