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
