    Incidence, clinical features, and outcomes of food allergy in children who underwent liver transplant: 16-year experience
    (2019) Baris, Zeren; Koksal, Burcu; Ozbek, Ozlem; Ozcay, Figen; Haberal, Mehmet; 0000-0001-9580-7656; 30884056; ABG-5684-2020; AAB-4153-2020
    Food allergies often develop after liver transplant, especially in young children. However, data are scarce on clinical characteristics and patient outcomes. When we evaluated our pediatric liver transplant patients over a 16-year period, food allergy incidence was 8% (19/236 patients). All patients with food allergies were <18 months old, with incidence in this age group of 19.2% (19/99). Two patients had a single food and 17 had multiple food allergies. Five patients showed only non-IgE-mediated food allergies. Eggs, milk, nuts, and wheat were the most common allergens. Presenting symptoms included diarrhea, flushing, angioedema attacks, wheezing/chronic cough, and vomiting. Seven patients had EBV, and two patients had CMV infections at time of food allergy diagnosis. Twelve patients had eosinophilia. Seven patients (36.8%) were able to regain tolerance to all food allergens. However, one patient with single nut allergy and three with multiple food allergies were still on allergen-eliminated diets. Eight patients with multiple food allergies gained tolerance to some of the food allergens. In conclusion, food allergies in our patients were mainly against multiple foods and IgE mediated. Infections like EBV and CMV may play a role in food allergies after liver transplant, especially in pretransplant-naive patients.
