Latest Insights on Food Protein-Induced Enterocolitis Syndrome: An Emerging Medical Condition

Area of Science:

• Allergy and Immunology
• Pediatric Gastroenterology

Background:

• Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated gastrointestinal food hypersensitivity.
• It presents acutely with profuse vomiting, pallor, and lethargy post-ingestion, or chronically with protracted symptoms and poor growth.

Purpose of the Study:

• To review the clinical manifestations, diagnosis, and management of FPIES.
• To highlight the increasing incidence and awareness of FPIES among pediatricians.

Main Methods:

• Review of clinical manifestations and diagnostic challenges.
• Discussion of common food triggers and diagnostic approaches.
• Emphasis on clinical suspicion due to lack of diagnostic tools.

Main Results:

• FPIES diagnosis relies on clinical presentation and high index of suspicion.
• Cow's milk, soy, grains, and fish are common triggers.
• Increasing incidence or awareness is noted in recent reports.

Conclusions:

• Early recognition and removal of the offending food are crucial for FPIES management.
• International guidelines for diagnosis and management are available.
• Prognosis is generally favorable, with most children outgrowing FPIES by age six.
