Background
Due to changes in dietary habits tree nuts (TN) are consumed in many
households and TN allergy appears to be increasing. One risk factor
seems to be allergies to other food such as peanuts. The aim of our
study was to investigate, how often peanut-sensitized infants and
toddlers are co-sensitized to cashew, hazelnut and walnut and to
determine the likelihood of its clinical relevance by their 2S
albumin-specific (s)IgE.
