[Coeliac disease in children--an update]

Area of Science:

• Immunology
• Gastroenterology
• Genetics

Context:

• Coeliac disease (CD) is an autoimmune disorder with a genetic basis, affecting individuals of all ages.
• CD presents with diverse clinical forms, including typical malabsorption, atypical extraintestinal symptoms, silent cases detected via screening, and potential/latent forms.
• Current diagnostic standards rely on anti-transglutaminase IgA antibody testing (with total IgA measurement) and subsequent intestinal biopsy.

Purpose:

• To outline the classification and diagnostic approaches for coeliac disease.
• To present the current gold standard for coeliac disease diagnosis.
• To evaluate the impact of oat consumption on gluten-free diets in pediatric coeliac disease.

Summary:

• Coeliac disease encompasses typical, atypical, silent, and potential/latent forms, each with distinct clinical and diagnostic profiles.
• The primary diagnostic pathway for coeliac disease involves serological testing for anti-transglutaminase IgA antibodies and confirmation via intestinal biopsy.
• Incorporating moderate amounts of oats into a gluten-free diet in children does not improve clinical outcomes or intestinal mucosal healing.

Impact:

• Provides a comprehensive overview of coeliac disease phenotypes and diagnostic strategies.
• Reinforces the importance of accurate serological and histological assessments for coeliac disease diagnosis.
• Offers crucial insights for dietary management in pediatric coeliac disease, advising against oats in gluten-free regimens.
