Celiac Disease in Children: A 2023 Update

Area of Science:

• Gastroenterology
• Immunology
• Genetics

Background:

• Celiac disease (CeD) is a chronic, immune-mediated enteropathy affecting genetically predisposed individuals upon gluten ingestion.
• Prevalence is 0.7% globally, impacting all ages with diverse clinical presentations, including non-classical symptoms like anemia and osteoporosis.
• Diagnosis relies on clinical history, serology, and duodenal biopsies.

Purpose of the Study:

• To outline the diagnostic criteria and management strategies for celiac disease.
• To highlight the importance of serologic testing and biopsy findings in definitive diagnosis.
• To emphasize the lifelong dietary management of celiac disease.

Main Methods:

• Utilizing IgA anti-tissue transglutaminase (tTG) as the primary serologic test for CeD detection.
• Employing duodenal biopsies with specific criteria (increased intraepithelial cells, villous to crypt ratio <2) for diagnosis.
• Monitoring healing via IgA-TGA levels post-diagnosis.

Main Results:

• High tTG-IgA and positive anti-endomysial IgA antibody (EMA) can diagnose CeD in children without biopsies.
• Biopsy findings of increased intraepithelial cells and a villous to crypt ratio <2 are suggestive of CeD.
• IgA-TGA serves as a marker for small-bowel mucosal healing.

Conclusions:

• Celiac disease diagnosis requires a combination of clinical, serologic, and histopathologic evidence.
• Lifelong adherence to a strict gluten-free diet is essential for managing CeD.
• Regular monitoring with IgA-TGA aids in assessing treatment efficacy and mucosal recovery.
