Rates Of Allergic Reactions In High Risk Infants During First Introduction Of Peanut

Results: 33 patients with a SPT above 8 underwent oral food challenge with a positive rate of 63%. A negative AraH2 had a NPV of 37% in this population. 5 patients experienced anaphylaxis in this cohort but none had severe anaphylaxis. There was no correlation between any specific patient characteristic (sensitization versus previous allergy) and risk of a positive challenge and/or anaphylaxis. There was trend towards higher threshold dose for positive challenges in this cohort and no patient with a negative AraH2 and anaphylaxis reacted on their first dose.
