The mean change in accuracy was 0.11 for Ara h 2, compared with 0.08 for Ara h 1 and 0.03 or less for other allergens. Adding IgE levels to the other 71 allergens and/or adding the IgG4 levels to Ara h 2 and Api g 1 (which showed a difference between PA cases and asymptomatic PS children) into this model led to no significant improvement in discriminative accuracy (data not shown). When a similar analysis was carried out for IgG4 levels, no allergen was found to contribute significantly to the prediction of PA (data not shown). Table?3 compares the diagnostic performance for IgE to Ara h 2 and for peanut sIgE at multiple cutoff points. The optimal cutoff point for Ara h 2 was 0.65 ISU-E, which corresponded to the lowest misclassification rate (1.2%). With this cutoff point, there were 99.1% sensitivity and 98.3% specificity for the diagnosis of PA. In comparison, the optimal cutoff for peanut sIgE (3.5?kUA/l) corresponded to a lower sensitivity (91.5%) and a higher misclassification rate (6.1%). Such difference was statistically significant when tested using estimated area under the receiver operating characteristic (ROC) curves (P?=?0.008). This is the first study to characterize CRD-based IgE and IgG4 reactivity profiles to 103 common allergens in U.S. Caucasian children and to evaluate their efficacy in the prediction of PA and/or peanut anaphylaxis. We demonstrated that IgE reactivity to Ara h 1�C3 and Gly m 5�C6 was clearly higher in children with PA than in asymptomatic PS children, and that IgE to Ara h 2 was the best candidate to discriminate PA from asymptomatic PS, which is consistent with findings in European populations [15-18]. However, all of these IgE and/or IgG4 tests had limited clinical value in the prediction of peanut anaphylaxis. In line with previous reports in European populations [15, 17, 18], our data showed that Ara h 2 is the most common peanut allergen recognized by IgE in U.S Caucasian children with PA (99.1%), followed by Ara h 1 (93.5%) and Ara h 3 (76.9%). In comparison, Ara h 8, which was recognized by 12.0% of PA cases and 13.8% of asymptomatic PS children, is a nonspecific minor peanut allergen. Significant IgE cross-reactive relationships were observed between Ara h 8 and the major birch allergen (Bet v 1), and several grass allergens, which supports the hypothesis that IgE directed against birch/grass allergens may bind to components of whole peanut extract leading to asymptomatic PS. A previous report in Britain demonstrated that peanut-tolerant children had a higher response to Timothy grass allergens (Phl p 1, 4, and 5b) than children with PA [15]. However, no such difference was found in our cohort. This inconsistency may be partly due to a relatively lower sensitization rate to birch/grass allergens in this cohort (
