Case of a 6-year-old boy with anaphylaxis induced by erythritol with positive skin prick test and negative basophil activation test

Abstract

Erythritol is widely used as an additive in foods and pharmaceuticals. We present the case of a 6-year-old boy who developed an allergy to erythritol. He showed a positive skin prick test result and a negative basophil activation test result. In cases involving allergens with low molecular weights, the test results should be carefully interpreted.
