While allergen avoidance remains the cornerstone of management of IgE-mediated egg allergy, graded allergen exposure (e.g. oral immunotherapy or an egg ladder) can build tolerance.
Maybe it’s time we try a gradual egg-sposure?
About 1.5% of young kids have an IgE-mediated reaction to egg. With eggs and egg-derived products ubiquitous in processed foods, strict allergen avoidance is difficult to maintain. While oral immunotherapy (OIT) is an effective method for building tolerance to egg protein, it requires many office visits, and access to this therapy is limited. Another method for graded exposure to egg protein is by increasing amounts of denatured egg protein via baked goods, or an egg ladder approach (similar to the milk ladder used to introduce cow’s milk protein to a toddler’s diet when they had intolerance as an infant).
This systematic review evaluated traditional allergen avoidance versus graded exposure strategies for managing pediatric IgE-mediated egg allergy. Including 28 studies, it found that graded exposure to baked/denatured egg – used in 22 studies – was generally safe, well-tolerated, and associated with high tolerance rates (70–92.7%).
Though allergen avoidance remains standard, it had no significant impact on building tolerance. Emerging graded protocols, including egg ladders, may accelerate tolerance acquisition and improve quality of life while reducing healthcare burden. In future research, it would be helpful for the definition of IgE-mediated egg allergy to be unified – that is, what combination of clinical history, skin prick testing, and serum tests qualify as true allergy?
How does this change my practice?
I see so many patients who have been told they have an allergy to egg based on unnecessary food allergen blood panels (i.e. without clinical history of allergic reaction). But without specific teaching around allergen avoidance, many of those patients are already ingesting egg-derived products or denatured egg protein without a reaction. It seems like those patients would be good candidates for the at-home egg exposure ladder.
