Food protein sensitivity with partial villous atrophy after pediatric liver transplantation with tacrolimus immunosuppression

Abstract

We report three pediatric liver transplant recipients receiving tacrolimus immunosuppression presented with vomiting, heme-positive stools and failure to thrive, who had subtotal villous atrophy in their histology because of food protein sensitivity. Case findings and current literature of the casual relationship between tacrolimus and food allergies briefly reviewed.
