Management of acute food protein-induced enterocolitis syndrome emergencies at home and in a medical facility

OBJECTIVE: Acute food protein-induced enterocolitis syndrome (FPIES) is characterized by delayed repetitive vomiting after ingestion of a trigger food, and severe reactions may lead to dehydration, hypotension, and shock. We provide recommendations on management of FPIES emergencies in a medical facility and at home.DATA SOURCES: This review summarizes the literature on clinical context, pathophysiology, presentation, and treatment of FPIES emergencies.STUDY SELECTIONS: We referred to the 2017 International Consensus Guidelines for the Diagnosis and Management of FPIES and performed a literature search identifying relevant recent primary articles and review articles on clinical management.RESULTS: Management of FPIES emergencies in a medical facility is based on severity of symptoms and involves rehydration, ondansetron, and corticosteroids. A proactive approach for reactions occurring at home involves prescribing oral ondansetron and providing an individualized treatment plan based on the evolution of symptoms and severity of past reactions. A better understanding of the pathophysiology of FPIES and randomized trials on ondansedron and cocorticosteroid use could lead to more targeted treatments.CONCLUSION: Children with FPIES are at risk for severe symptoms constituting a medical emergency. Management of FPIES emergencies is largely supportive, with treatment tailored to the symptoms, severity of the patient's condition, location of reaction, and reaction history.
