Özet

Background: The time to acquisition of tolerance to unheated milk and regular egg after achievement of tolerance to baked goods is not known. Objective: To determine the time to acquisition of unheated-milk-regular-egg tolerance, after the tolerance of the baked forms, in children younger than 2 years. Methods: An initial oral food challenge with baked milk (BM) and baked egg (BE) was performed on patients who were reactive to unheated milk-regular egg, respectively. Patients who were BM-BE tolerant were offered unheated-milk-regular-egg challenges, and patients who were BM-BE reactive were offered BM-BE challenges at an average of 3-month intervals. Food-induced atopic dermatitis was included. Results: Thirty-six children with unheated-milk allergy (median age, 7.3 months [interquartile range (IQR), 6.0-13.5]) and 65 with regular-egg allergy (median age, 7 months [IQR, 5.8-11.0]) were included. Seven of 13 children who were BM tolerant acquired unheated-milk tolerance after a median 4.0 months (IQR, 2.0-7.0). Twelve of 23 children who were BM reactive acquired unheated-milk tolerance after a median 5.0 months (IQR, 3.0-8.0) after BM tolerance. Twenty-one of 29 children who were BE tolerant acquired regular-egg tolerance after a median 3.0 months (IQR, 1.0-6.0). Sixteen of 36 children who were BE reactive acquired regular-egg tolerance after a median 4.0 months (IQR, 2.0-6.8) after BE tolerance. Conclusion: Different tolerance rates were determined for baked products at different time points in the first 2 years of life. Unheated-milk-regular-egg allergy resolved in up to 65.5% and 75.5% of cases, respectively, in an average 4 to 5 months after acquisition of BM-BE tolerance. Baked-milk-baked-egg tolerance may be regarded as a precursor of tolerance. (c) 2022 American College of Allergy, Asthma & Immunology. Published by Elsevier Inc. All rights reserved.
