Transfer of Symptomatic Peanut Allergy to the Recipient of a Combined Liver-And-Kidney Transplant

Abstract
Peanuts are one of the commonest causes of food allergy in the United States and Europe.1-3 They are also a leading cause of food-induced anaphylaxis and death, which usually follow inadvertent exposures.4,5 Allergy to peanuts is an IgE-mediated, mast-cell–dependent, immediate-hypersensitivity reaction. There are several reports of the transfer of allergen-specific IgE-mediated hypersensitivity by bone marrow transplantation.6-9 We report a case of peanut allergy transmitted through combined liver-and-kidney transplantation.
