2 What is Gluten?

3 What is Gluten? Gluten is the collective term for a group of proteins found in the grains wheat, rye and barley and their various forms (i.e., spelt, einkorn, triticale)! It is best known for giving baked goods their doughy, elastic structure, however many foods contain gluten for other purposes, including as a thickening agent or flavor enhancer! For people with celiac disease (CD), every time gluten is consumed the immune system triggers an attack on the intestines. When the villi of the intestines become damaged, the body is unable to absorb nutrients into the bloodstream, which can lead to malnourishment and other serious chronic conditions! People with non-celiac gluten sensitivity (NCGS) may experience similar symptoms as those with CD, however, antibodies to gluten are not produced nor is there intestinal damage (two hallmarks of CD). We do not yet know if eating small amounts of gluten causes damage.

4 Why Go Gluten-Free? Comparing and Classifying Gluten-Related Disorders

5 Nomenclature and classification of gluten-related disorders Source: Fasano A, et al. Spectrum of gluten-related disorders: consensus on new nomenclature and classification. BMC Medicine. 2012; 10:13.

6 Comparison of Gluten-Related Disorders Celiac Disease Wheat Allergy Non-Celiac Gluten Sensitivity Autoimmune disorder Immune system triggers attack on intestines when gluten is eaten Blood tests reveal autoantibodies to gluten; biopsy reveals intestinal damage Affects 1% of population 3 million Americans Allergic (IgE-mediated) immune response Affects 0.1% of population 300,000 Americans Not autoimmune disorder No auto-antibodies to gluten; no intestinal damage Not allergic disorder No disease definition yet Diagnosis of exclusion 6% of population? No biomarker yet 300+ symptoms have been reported: - Intestinal - Extra-intestinal - No symptoms Swelling/itching; hives/rash; itchy watery eyes; difficulty breathing; anaphylaxis Symptoms mirror CD Extra-intestinal symptoms more likely

8 Diagnostic Testing

9 Testing for CD: The 5 Pillars of Diagnosis 1. Signs or symptoms compatible with CD 2. Positive serological screening tests (need to be eating gluten for accurate results) 3. Presence of genetic markers: HLA-DQ2 or HLA-DQ8 4. Intestinal damage typical of CD detected by endoscopy/biopsy (need to be eating gluten) 5. Symptom resolution following implementation of gluten-free diet Dr. Alessio Fasano says in his book, Gluten Freedom: The majority of people with CD will meet all five criteria, but there are exceptions to each of these pillars. As a result, meeting four of the five criteria should be sufficient to cover most people with CD and may prevent the need for using one of the criteria (i.e., invasive endoscopy/biopsy in children

10 Genetic Testing for Celiac Disease 30-40% of population has one or both genes; however, only 1-3% develops CD Having one or both genes only shows you may develop CD; it is not a confirmed diagnosis for CD Physicians primarily use genetic testing to rule out CD Other reasons for recommending genetic testing: in young children who have family history; if negative, no need for invasive procedures or lifelong monitoring for those who may have other conditions with similar changes/damage to intestines for those who have self-diagnosed as being gluten sensitive, have been gluten-free for several months, and do not want to undergo a gluten challenge for formal testing

11 Testing for Non-Celiac Gluten Sensitivity (NCGS)? Currently, there is no accepted diagnostic test for NCGS NCGS is a diagnosis of exclusion first rule out celiac disease and wheat allergy through proper testing then conduct elimination diet to determine if gluten is really the trigger other components of wheat may be the cause of symptoms Elimination diet should be done under supervision of healthcare team with gluten-related disorders expertise
