Celiac.com 04/18/2016 - In the last 3 years, there has been an evolving spectrum around celiac disease and gluten sensitivity. The acceptance of Non-Celiac Gluten Sensitivity (NCGS) in the medical community as a distinct clinical entity has gone from that of being an orphaned child crying in the world for recognition, to an accepted, unique component of the triad of gluten-related disorders.(i) Differentiating among gluten-related disorders, guides clinicians in making an accurate diagnosis and recommending specific dietary, nutritional and other medical advice; however, clinical and laboratory diagnosis is complex and evolving.(ii)
Gluten sensitivity is a state of heightened immunological responsiveness to ingested gluten in genetically susceptible people. It represents a spectrum of diverse manifestations, of which, the gluten sensitive enteropathy known as celiac disease is one of many. Adverse reactions to the toxic family of gluten proteins found in wheat, barley, rye, and their derivatives may trigger a heterogeneous set of conditions, including wheat allergy (IgE), NCGS, and celiac disease, that, combined, affect between 10–35% of the population.(iv,v,vi,vii)
2. The prevalence of celiac disease varies by race/ethnicity, with a marked predominance among non-Hispanic whites.
3. With more sophisticated diagnostic markers now available, the majority of celiac disease cases are being recognized.
6. What percent of individuals with NCGS suspect they may have a problem with wheat?
7. Of the following three scenarios, which is the most dangerous for increased mortality in celiac disease?
A. Total villous atrophy
B. Positive celiac serology with negative villous atrophy
C. Increased intraepithelial lymphocytes (IEL) with negative serology and negative villous atrophy
8. In differentiating wheat sensitivity from IBS, which one of the following features is significantly more frequent in wheat sensitive patients compared to IBS patients?
B. Self-reported fructose intolerance
C. Weight gain
D. Self-reported lactose intolerance
9. Compared to patients with celiac disease, what are the characteristic features, other than self-reported wheat intolerance, of patients with wheat sensitivity?
A. Anemia and family history of celiac disease
B. Weight loss and increased IEL count
C. Coexistent atopy and food allergy in infancy
D. Increased serum C reactive protein and erythrocyte sedimentation rate
Current therapeutic protocols for celiac disease, NCGS and wheat allergy include dietary counseling from a trained professional, nutritional therapy addressing biomarkers of malabsorption and creating a more balanced intestinal environment.(ix) Currently, there are no approved pharmaceutical treatments for this silent epidemic, however a number of Phase 3 trials are underway. Promising gluten-based research is currently being done including wheat alternatives and wheat selection, enzymatic alteration of wheat, oral enzyme supplements and polymeric binders as exciting new therapies for treatment of celiac disease.
There appears to be at least two distinct groups of NCGS individuals. There are those who are sensitive to wheat and those who have multiple food sensitivities. Furthermore, the multiple food sensitivity group had a higher prevalence of coexisting atopy or food allergy in infancy.(xi) It is critically important to identify whether a NCGS individual has multiple food sensitivities or exclusively has NCGS.(xii) This suggests the world of NCGS is greater than just one mechanism and invites the clinician to explore its pathophysiology.
