Growing Out of Egg Allergy

Summary
This was a retrospective analysis of 881 patients evaluated for egg allergy. The patients were followed for a median of six years. The results were as follows:

  • 4% had outgrown egg allergy by age 4
  • 12% had outgrown egg allergy by age 6
  • By age 10, 37% had outgrown their egg allergy
  • By age 16, 68% no longer had egg allergy
  • Higher egg IgE levels predicted persistence of allergy through childhood
  • The majority of children with egg IgE levels of 50 kU/L failed to tolerate egg by age 18
  • The presence of multiple food allergies also indicated a greater chance for persistence of allergy to egg
