An oral food challenge (OFC) is useful for managing food allergies. However, because OFCs have the risk of severe allergic reactions, including anaphylaxis, conducting OFCs under this situation without allergy specialists is difficult. To investigate the safety of a low-dose OFC for eggs, milk, and wheat in a general hospital without allergy specialists. We retrospectively analyzed the medical records of children who were hospitalized in a general hospital without allergy specialists for a low-dose OFC of egg, milk, or wheat between April 2018 and March 2021. The records of 108 patients were evaluated. The median age was 15.8 months (range: 7.5–69.3 months). Challenged foods were eggs (n = 81), milk (n = 23), and wheat (n = 4). Fifty-three (49.0%) patients showed positive allergic reactions. Thirty-five (66.0%) patients showed grade 1 (mild), 18 (34.0%) showed grade 2 (moderate), and none showed grade 3 (severe) reactions. The interventions comprised antihistamines (n = 18), prednisolone (n = 3), inhaled β2-agonist (n = 2). No patients required adrenaline and no deaths occurred. Low-dose OFCs may be safe in a general hospital without allergy specialists. Conducting a low-dose OFC may be essential in food allergy practice. |
