Podcast 827: Allergies in Peds

Contributor: Aaron Lessen, MD

Educational Pearls:

• Recent study evaluated if early exposure to an allergen impacted the rate of allergy development later in childhood
• Children were exposed to peanut, milk, wheat, and egg allergens at 3 months of age and then followed for 3 years
• 2.5-3% of children who were not exposed developed allergies to these allergens
• 1% of children exposed to the allergens developed allergies to these allerrgens
• Exposing 63 children to allergens at 3 months would prevent the development of food allergy in one child with no significant adverse events
• Future recommendations will likely be to gradually introduce allergens to children starting around 3 months
