TWO SCHOOL-AGED CASES OF FRUIT GIBBERELLIN-REGULATED PROTEIN ALLERGY WHICH NEED INDIVIDUAL REMOVAL STRATEGY IN SCHOOL LUNCH

Abstract

Gibberellin-regulated protein (GRP) is a newly discovered allergen in systemic fruit allergies. The kind of fruits which cause allergy is extensive as GRP is universally included in plants. Two children with GRP allergy were reported. Case 1: A 6-year-old boy experienced anaphylaxis while running after school lunch, which included canned peaches. A skin prick test (SPT) and blood examination suggested that he had peach GRP allergy. Six months and three years later, he experienced a similar episode after eating apple and citrus flesh, respectively. Case 2: An 11-year-old boy experienced anaphylaxis while running after consuming canned peaches during school lunch. A SPT implied that he had peach GRP allergy. However, a similar episode occurred after eating strawberry flesh 18 months later.Patients with GRP allergy often have one or more allergies to fruits other than peaches, as in these cases, and relevant fruits differ depending on the case. Particularly, clinicians should recognize that apple and citrus fruits are frequently included in school lunches as fruit flesh and as flavoring or seasoning in ready-made sauces or dressings. Therefore, an appropriate removal strategy should be considered in school lunches depending on each case of GRP allergy.
