Thirteen patients (median age 10 years, range (7-15) with a history of high-risk peanut allergy, including histories of severe reactions, were recruited (median peanut-specific IgE) was 229 kU/L, range of 21-617 kU/L, the highest median for any oral peanut desensitization study, as far as we know) (median total IgE, 621 kU/L) [29]. Here, IGHE is linked to peanut allergic reaction.
