[Neonatal food allergy].

Area of Science:

• Immunology
• Gastroenterology
• Pediatrics

Context:

• Food allergy involves abnormal immune responses to ingested foods.
• Mechanisms include gut barrier dysfunction, impaired oral tolerance, and prenatal sensitization.
• Genetic and environmental factors play a role in food allergy development.

Purpose:

• To define food allergy and elucidate its underlying mechanisms.
• To outline diagnostic standards and treatment strategies for neonatal food allergy.
• To explore the potential protective role of probiotics.

Summary:

• Food allergy is an immune reaction to food, leading to diverse symptoms from mild gastrointestinal issues to severe systemic reactions like shock.
• Diagnosis relies on oral food challenges, the gold standard, while management focuses on strict avoidance of trigger foods.
• Emerging research suggests probiotics may confer protection against food allergies, offering a potential therapeutic avenue.

Impact:

• Highlights the complexity of food allergy, encompassing immunological, gastrointestinal, and environmental factors.
• Emphasizes the critical role of accurate diagnosis and effective management in preventing severe complications.
• Suggests a promising preventive or therapeutic strategy using probiotics in managing food allergies.
