IGHE and Alzheimer disease: According to logistic regression analysis, family history of atopy (OR 5.4 [1.2–25.4]; p = 0.031), concomitant atopic dermatitis (AD) (OR 8.2 [1.7–40.7]; p = 0.010), rectal bleeding duration >18 days before starting elimination diet (OR 5.9 [1.3–27.7]; p = 0.023) and IgE sensitization (OR 6.4 [1.2–35.0]; p = 0.034) were adequate factors associated with food tolerance that may potentially function as predictors of late tolerance acquisition to CM (Table 4).
