RESUMO
INTRODUCTION AND OBJECTIVE: The oral food challenge (OFC) is the gold standard to diagnose food allergy (FA); however, it is not a procedure free from the risk of having significant allergic reactions, even life-threatening.The aims of our study were to evaluate the frequency of positive OFCs performed in children with a suspected diagnosis of IgE- and non-IgE-mediated (food protein-induced enterocolitis syndrome (FPIES)) FA and how the failed challenges were managed. MATERIALS AND METHODS: A retrospective chart review was done on all children who have had OFCs in a tertiary-care pediatric allergy unit from 2017 to 2019. RESULTS: 682 patients were enrolled and 2206 challenges were performed: 2058 (93%) for IgE-mediated FA and 148 (7%) for FPIES. There were 262 (11.8%) challenge failures. The transfer to the emergency department was required 3 times (1.1%). None of the failed challenges resulted in death or hospitalization and 13.3% challenges did not require any treatment. CONCLUSIONS: Our findings confirm that food challenges can be performed safely in a specialized setting by well-trained personnel; all food challenge reactions, even the most serious, were reversible, thanks to a prompt recognition and treatment that generally did not worsen over time.
