Abstract
Background: There have been few practical reports of dietary intervention near the threshold of allergic reactions for food allergy. Herein, we report a case of a food allergic child who was successfully treated for egg and wheat allergy by oral food challenge (OFC) and dietary intervention, not oral immunotherapy. Case presentation: A 4-year-old boy who developed anaphylaxis at seven months of age. He showed high specific IgE values and was skin prick test-positive for egg, milk, and wheat. He was recommended to completely avoid these allergens by a previous doctor. He experienced six incidences of food-induced anaphylaxis to these allergens before visiting our hospital. We repeatedly instructed the patient in dietary management at the outpatient department. Consequently, he managed to avoid the restriction of wheat and egg and achieved a satisfactory diet menu. Conclusion: We concluded that the elimination of allergens is possible by gradually increasing the target dose of causative foods under evaluation by OFC.
