Optimizing the diagnosis of celiac disease

Area of Science:

• Gastroenterology
• Immunology
• Internal Medicine

Background:

• Celiac disease is a common condition often underdiagnosed.
• Understanding its pathophysiology is crucial for diagnostic optimization.

Purpose of the Study:

• To summarize contemporary research for optimizing celiac disease diagnosis.
• To review evolving diagnostic approaches and emerging strategies.

Main Methods:

• Discussion of updated National Institute for Health and Care Excellence (NICE) and European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) guidelines.
• Review of evidence on biopsy techniques (single bite, bulb biopsy) for increased diagnostic yield.
• Analysis of phenotypical characterization and outcomes of celiac disease subtypes (potential, seronegative, ultrashort).
• Presentation of novel case-finding strategies, including point-of-care tests and biomarkers (serum intestinal fatty acid binding protein, in-vitro gluten challenge).

Main Results:

• Updated guidelines and a biopsy-free approach are discussed.
• Optimal biopsy techniques aim to increase diagnostic yield.
• Phenotypical characterization of celiac disease subtypes is presented.
• Emerging evidence on novel case-finding strategies and biomarkers is included.

Conclusions:

• Celiac disease subtypes have clinical significance, requiring careful diagnosis.
• A trend towards less invasive and more cost-effective diagnostic methods is observed.
• Duodenal biopsy remains the current gold standard for diagnosing celiac disease in most adults and pediatric patients.
