IgE-mediated allergy to egg protein

Area of Science:

• Immunology
• Pediatrics
• Allergology

Background:

• Egg allergy is a prevalent food allergy in children, significantly affecting their quality of life.
• It is an immune-mediated adverse reaction, specifically focusing on immunoglobulin E (IgE)-mediated responses in this review.
• Prevalence is higher in children with co-existing conditions like cow's milk allergy and atopic dermatitis.

Purpose of the Study:

• To review the current understanding of immunoglobulin E (IgE)-mediated egg allergy in pediatrics.
• To discuss diagnostic approaches, management strategies, and emerging therapeutic options.
• To highlight the importance of accurate diagnosis and the potential of food immunotherapy.

Main Methods:

• Review of existing literature on egg allergy, focusing on IgE-mediated mechanisms.
• Analysis of diagnostic criteria, including clinical history, specific IgE testing, and oral food challenges.
• Examination of current management strategies, including avoidance diets and symptomatic treatment.
• Evaluation of food immunotherapy as a therapeutic option for IgE-mediated egg allergy.

Main Results:

• The primary allergens in egg white are ovomucoid and ovalbumin.
• Oral food challenge is the gold standard for confirming egg allergy diagnosis.
• Current management emphasizes accurate diagnosis and minimizing restrictive diets, with oral immunotherapy being a key therapeutic option.
• Food immunotherapy has demonstrated potential to increase tolerance and reduce anaphylaxis risk.

Conclusions:

• Accurate diagnosis through component-resolved diagnostics and oral challenge tests is crucial for managing egg allergy.
• Minimizing dietary restrictions is a key goal, making immunotherapy a valuable therapeutic consideration.
• Oral immunotherapy is the most studied and widely used approach for treating IgE-mediated egg allergy, offering potential for tolerance induction and reduced reaction severity.
