Celiac Disease and Gluten Sensitivity.

Area of Science:

• Gastroenterology
• Immunology
• Internal Medicine

Background:

• Celiac disease is an immune-mediated enteropathy caused by gluten ingestion in genetically susceptible individuals.
• It leads to intestinal symptoms and malabsorption, necessitating accurate diagnosis and management.
• Differentiating celiac disease from gluten sensitivity symptoms can be challenging.

Purpose of the Study:

• To outline the diagnostic pathway for celiac disease.
• To emphasize the importance of a gluten-free diet in management.
• To provide guidance for patients with symptoms suggestive of gluten intolerance but without confirmed celiac disease.

Main Methods:

• Diagnosis involves serological testing for anti-tissue transglutaminase IgA antibodies.
• Histologic examination of small bowel biopsy is crucial for confirmation.
• Management strategies include dietary modifications and further investigations for persistent symptoms.

Main Results:

• Stepwise evaluation with serology and biopsy confirms celiac disease.
• Strict adherence to a gluten-free diet is the cornerstone of treatment.
• Patients without celiac disease but with gluten-related symptoms require a tailored approach.

Conclusions:

• Accurate diagnosis of celiac disease relies on specific serological and histological findings.
• A gluten-free diet is essential for managing celiac disease.
• For non-celiac gluten sensitivity, nutritional counseling and evaluation for other conditions like small intestinal bacterial overgrowth or IBS are recommended.
