(This is the first in a series of posts on our experiences as we trial our son who has multiple food allergies with oral food challenges at home. Oral food challenges should always be performed under direct medical supervision based on each patient’s individual reaction history. Please do not try oral food challenges at home on your own without medical approval.)
After our son had an allergic reaction during his egg allergy oral challenge, we found ourselves with more questions than we had answers. Did he really react to the baked egg? Could he have reacted to something environmental? What if a mild cold caused his breathing difficulties that night. Should we try the baked egg oral immunotherapy again since he safely ate baked eggs the month before with no reaction?
The next morning we called our son's allergist. With all the questions and outside factors that could have affected our baked egg challenge, he wanted to try the baked egg oral immunotherapy again after Mitch cleared up.
Our allergist explained to us that the immune system is like an empty cup that slowly fills with each allergen received until the cup runs over and a reaction occurs, and it doesn't necessarily take just one large dose of one allergen to create a reaction, but many small doses of many allergens can cause a reaction. This is what he believed happened to Mitch.
Baked Egg Oral Immunotherapy Trials
In an article in The Journal of Allergy & Clinical Immunology (JACI), when baked egg oral immunotherapy was performed, those children who tolerated baked egg added baked egg products to their diet on a regular basis.
In this study, 89% of the 79 subjects now tolerate baked egg and 53% now tolerate regular egg. The results of this study confirm that a majority of egg-allergic children tolerate baked egg and indicate that long-term ingestion of baked egg is well tolerated and accelerates the development of regular egg tolerance compared with strict avoidance.
This week he wants to continue the baked egg oral food challenge with Mitch, essentially beginning baked egg oral immunotherapy trials to help Mitch develop a tolerance to baked egg, and possibly even a regular egg.
