Walnut
sIgE to the 2S albumin Jug r 1, the cupin Jug r 2, and the nsLTP1 Jug r
3 (AUC=0.79, 0.70, 0.62, resp.) predicted anaphylaxis in 45
walnut-allergic children.277 In 91 walnut-allergic
subjects from Switzerland, Germany and Spain, severe reactions
correlated with higher sIgE levels to Jug r 1 and the cupin Jug r
4.278 sIgE to Jug r 1 (AUC=0.79) from 32
walnut-allergic Korean children better discriminated clinical walnut
allergy from tolerance than sIgE to walnut extract
(AUC=0.56).279 In 34 peanut-, hazelnut- or
walnut-allergic Italian children, sIgE to Ara h 1 and Ara h 2, Cor a 9
and particularly Cor a 14, or Jug r 1, 2 and 3 was associated with
anaphylaxis.280
