Impact statement
Sensitization to hazelnut, cashew and walnut seems to be common among
peanut-sensitized infants and toddlers. They also seem to be frequently
sensitized to the corresponding tree nut 2S albumins, what might be
associated with clinical reactivity to these tree nuts. Based on our
findings, it should be considered to test peanut-sensitized infants and
toddlers also for sensitization to tree nuts if these have not been
introduced into the diet so far.
