Food Protein-Induced Enterocolitis Syndrome.

Area of Science:

• Pediatric Allergy and Immunology
• Gastroenterology

Background:

• Food protein-induced enterocolitis syndrome (FPIES) is a non-immunoglobulin E-mediated food allergy.
• Typically presents in infancy with common triggers including cow's milk, soy, and grains.
• FPIES can manifest as a severe medical emergency.

Purpose of the Study:

• To summarize the key aspects of FPIES diagnosis and management.
• To highlight the clinical presentation and common triggers of FPIES.
• To emphasize the diagnostic approach, including the role of oral food challenges.

Main Methods:

• Clinical history review to identify potential food triggers.
• Observation of symptom improvement upon elimination of suspected foods.
• Oral food challenge as the gold standard for diagnosis in ambiguous cases.

Main Results:

• Delayed persistent emesis and diarrhea are hallmark symptoms of FPIES.
• Severe dehydration and hemodynamic instability can occur, accompanied by abnormal laboratory markers.
• Dietary elimination of trigger foods leads to symptom resolution.

Conclusions:

• FPIES diagnosis is often based on clinical history and response to dietary modification.
• Oral food challenges are crucial for confirming FPIES in uncertain situations.
• Prompt recognition and management are essential to prevent severe complications.
