Abstract:
We present a case of walnut allergy in a 24-year-old man. The allergy work up revealed sensitization to walnut including a positive skin prick test and a high value of walnut-specific IgEs. The patient showed an anaphylactic reaction during the double blind placebo-controlled food challenge, to a cumulative dose of 3.723 g of walnut protein. The oral food challenge resulted in counseling regarding strict walnut avoidance and optimization of the emergency management. At follow-up the patient reported that having adhered to the recommended dietary measures resulted in no further allergic reactions.
