IGHE and hereditary elliptocytosis: Our results show that although OM-sIgE levels in children younger than 2 years and the peak egg white IgE levels >50 UA/ml were significantly higher in the low-dose HE reactor group than in the HE tolerance group, multivariate logistic regression analysis revealed that avoidance of HE was associated with low-dose HE reactor even after adjusting the OM-sIgE levels at <2 years of age or the peak egg white IgE levels >50 UA/ml, respectively.
