Results:
169 individuals with 329 recorded FPIES episodes between 1997 and 2017
were included. 49% were male. The median age at first FPIES reaction
was 5 months and median age at diagnosis was 9 months. 73% experienced
at least one severe FPIES reaction. Rice (45%), cow’s milk (30%), soy
(13%) were the most common triggers. FPIES to rice or cow’s milk were
strongly associated with increased odds of having multiple trigger
FPIES. The odds of having multiple food FPIES and severe reactions were
slightly decreased with vaginal delivery. No factors were associated
with increased risk of severe reactions. Infants with rice and grains
FPIES outgrew their reactions at an earlier age, compared to those with
fish FPIES.
