Food Protein-Induced Enterocolitis Syndrome

Area of Science:

• Allergy and Immunology
• Pediatric Gastroenterology
• Clinical Nutrition

Background:

• Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE mediated gastrointestinal food allergy.
• Primarily diagnosed in infants, FPIES can also affect older children and adults.
• Acute FPIES presents with delayed vomiting and lethargy; chronic FPIES involves poor growth.

Purpose of the Study:

• To enhance awareness and reduce delayed or missed diagnoses of FPIES.
• To highlight the importance of detailed diagnostic criteria for FPIES.
• To provide a comprehensive overview of FPIES presentation and triggers.

Main Methods:

• Literature review of FPIES cases and diagnostic criteria.
• Analysis of common food triggers for FPIES.
• Synthesis of clinical presentations for acute and chronic FPIES.

Main Results:

• FPIES is triggered by common foods like cow's milk, soy, rice, oats, fish, and egg.
• Acute reactions manifest 1-4 hours post-ingestion with vomiting and lethargy.
• Chronic FPIES is characterized by persistent GI symptoms and growth issues.

Conclusions:

• Detailed diagnostic criteria are crucial for accurate FPIES identification.
• Increased awareness can lead to earlier and more precise diagnoses.
• FPIES requires careful consideration in differential diagnoses of pediatric and adult GI disorders.
