Abstract
Background
Oral food challenges (OFCs) assist in the diagnosis of food allergies and are essential to determine whether an allergy has been outgrown. During the OFC, a medical procedure e introduces foods suspected to be allergenic orally in increasing doses. Mild skin reactions such as urticaria or rarely serious life-threatening reactions such as anaphylaxis may develop.
Objective
In this study, we aimed to retrospectively evaluate the clinical and laboratory characteristics of patients who experienced anaphylaxis during open OFCs in a tertiary care children’s hospital.
Methods
Patients who underwent OFCs to confirm the presence of a food allergy or to assess tolerance status at the University of Health Sciences, Ankara, Dr. Sami Ulus Maternity and Children Training and Research Hospital, Pediatric Allergy and Immunology Outpatient Clinic between 1 January 2013 and 1 February 2016, were included in the study. Patients’ data were obtained retrospectively from electronic medical records and challenge chart reviews.
Results
A total of 623 OFCs were performed during the period studied. Nine patients (1.4%) between 13 and 67 months of age (mean age: 38.3 months) developed anaphylaxis during their OFC.
Conclusion
OFCs should be performed in a hospital or outpatient office under medical supervision that is adequate for anaphylaxis intervention by an allergy specialist. Close observation of objective and subjective symptoms is essential during the challenge because there are no laboratory tests that can predict an anaphylactic diagnosis or the severity of the reaction.
