De novo multiple food allergy after liver transplantation: A case report

Abstract

Food allergy is defined as an immune-mediated response to food. Food allergy after solid organ transplantation was first described in 1997 after liver and kidney transplantation. Three years- five-month-old male was admitted with lip swelling after food intake. He had received a liver transplant from a living donor at ten months of age due to biliary atresia. Treatment with tacrolimus and mycophenolate mofetil was monitored. He was admitted to the emergency department with complaints of lip swelling that developed immediately after eating eggs in our department at 20 months of age. No associated respiratory, skin or gastrointestinal findings were noted in the case, who had previously eaten eggs without any problems. Later, after eating honey and tahini mixture and corn with mayonnaise sauce at different times, swelling developed on his lips and eyes. According to the tests, eggs, peanuts, and hazelnuts were excluded from the patient’s diet. The case was followed with diet therapy for two years with no problems. Organ donors should be screened for food allergies to predict organ recipients’ risk for new food allergies after transplantation. Although there is no evidence of food allergy in the donor, it should be kept in mind that new food allergies may develop in patients who have undergone solid organ transplantation, and patients should be monitored in this regard.
