Background: Clinical Practice Guidelines (CPG) from both adult medicine and pediatrics recommend tTG to screen for celiac disease (CD).

Design And Methods: Serological test orders for celiac disease were evaluated against the guidelines. Ordering physicians were categorized as gastroenterologists, immunologists, pediatricians, other hospital physicians and non-hospital physicians. Interventions based on initial audit were implemented, including interacting with physicians, revising test menu and changing test ordering policy. After implementation of interventions, test orders were re-evaluated.

Results: After corrective interventions celiac panel (CP) orders were decreased from 48.4% to 3.6% in children, and from 72.3% to 28.1% in adults. Physicians ordered tTG alone for more than 90% of children. In adults the ordering of tTG alone was significantly increased from 7.2% to 61.3% (from 8.9% to 63.9% for gastroenterologists and from 8.1% to 44.4% for other physicians (p<0.05)).

Conclusions: The audit reduced the CPG-practice gap that existed in the screening of CD.

Introduction: Non-Celiac Gluten Sensitivity (NCGS) is a common disorder characterized by symptoms resembling those of irritable bowel syndrome. In recent years there has been progress in the understanding of the pathogenic pathways and data suggest that NCGS has a distinct immunological profile that differs from celiac disease (CeD). This has fostered the search for a specific biomarker of NCGS.

Purpose Of Review: Celiac disease (CeD) is a chronic autoimmune disorder of the small intestine triggered by gluten ingestion in genetically predisposed individuals. The cornerstone of CeD management remains a strict adherence to a lifelong gluten-free diet (GFD), although such a dietary restriction can lead to an altered quality of life and may not be easy to follow for many patients. These challenges highlighted the need for alternative therapies.
