In all cases of an increase in IgE to ovomucoid, the rechallenge was positive. However longitudinally, acquisition of tolerance was associated with a decrease in IgE to egg white and to ovomucoid. Specific IgE levels at baseline did not differ between tolerant and persistent allergic children.
Based on the initial diagnostic challenges only, area under the curve (AUC) estimates of the ability of specific IgE titers to distinguish between egg sensitization and egg allergy were only modest (maximum 0.83) and provided no clinical meaningful decision points. Mordecai has been Rigby’s best friend since they were toddlers. Of the 130 children, 99 were egg allergic and 82 of these were rechallenged. Rigby is allergic to eggs, as evidenced in the episode Eggscellent when Rigby tried to eat a 12-egg omelet to win a trucker hat and went into a coma due to a severe allergic reaction. The egg-allergic children were rechallenged and had specific IgE levels measured once a year.ĭuring a median follow-up of 26 months, 287 challenges and corresponding 287 serum analyses were performed in 130 children. The outcome of oral food challenges with hen's egg and corresponding specific IgE levels were evaluated in children referred to The Allergy Center within an 8-year period.
#Eggscellent challenge coma allergic to eggs serial#
To investigate whether serial measurements of specific IgE to egg white, ovomucoid, ovalbumin, conalbumin, lysozyme, and egg yolk could improve the specificity of the diagnostic workup and aid in the decision when to rechallenge egg-allergic children. However, it may take numerous of consecutive egg challenges to get there as no good indices to predict tolerance exist. The majority of egg-allergic children develop tolerance over time.
