Peanut Allergy: Changes in Dogma and Past, Present, and Future Directions.

The prevalence of food allergy in the pediatric population, specifically to peanuts, has been rising. Accidental exposure to peanuts in a person who is allergic may have life-threatening consequences. Previous recommendations regarding peanut allergy included a delay in introduction of peanut to infants. However, more recent studies have provided sufficient contrary evidence supporting early introduction of peanuts for prevention of peanut allergy. Therefore, prompt evaluation by a specialist should be considered in infants at high risk of developing peanut allergy. Current treatment is strict avoidance of the allergen; however, future therapies are being sought, including oral immunotherapy, sublingual immunotherapy, and epicutaneous immunotherapy.
