BACKGROUND: It was once thought that @entity16244 is a lifelong problem. We previously reported that about 20% of @entity1 outgrow their @entity16244 and that more than 60% of @entity1 with a peanut-IgE level of 5 or less passed an oral challenge. OBJECTIVE: The goal of this study was to further describe the natural progression of @entity16244 by reviewing @entity1 who have undergone oral peanut challenges since the previous study. METHODS: @entity1 with peanut-IgE levels of 5 or less were offered a peanut challenge. Those who passed were further evaluated by questionnaire to assess reintroduction of peanut into their diet and whether any recurrence has occurred. RESULTS: Eighty-four @entity1 were evaluated, and 80 underwent complete analysis. Fifty-five percent with peanut-IgE levels of 5 or less and 63% with peanut-IgE levels of 2 or less passed challenges, compared to 61% and 67%, respectively, in our previous study. The 4 additional @entity1 passed peanut challenges in this study after previously failing. Three @entity1 with initial anaphylactic reactions and 2 @entity1 with initial peanut-IgE levels greater than 70 passed their challenge. Follow-up of those who passed in both studies showed that the majority of @entity1 reintroduced peanut into their diet, but that continued label reading, infrequent/limited ingestion, and aversion to peanut were all common in this population. Two @entity1 had suspected subsequent reactions to peanut after passing their challenge. CONCLUSIONS: @entity1 with a @entity16244 and peanut-IgE levels of 5 or less have at least a 50% chance of outgrowing their @entity566 . Recurrence of @entity16244 may occur but appears to be uncommon.
