Introduction Intestinal epithelial cell damages generated by inflammation in coeliac disease (CD) ranges from sub-microscopic to severe architectural distortion. Translation of quantitative morphological changes in intestinal microorgans, like villus/crypt transformation, distribution of inflammatory cells and diagnostic cut offs, is lacking for CD and gluten related micro-enteropathies. Method Investigators from 22 centres, 9 countries of 4 continents, recruited CD patients with Marsh 0-II histology (n=299), NCGS (n=151), and 262 controls. Based on an agreed protocol, epithelial morphology including intraepithelial lymphocyte (IEL) density, villus height and crypt depth were measured in well-oriented duodenal biopsies. Results In total 712 subjects were recruited from Australia (20), Finland (20), India (25), Iran (37), Italy (246), Romania (10), Turkey (30), UK (166) and USA (158). Preliminary analyses showed raw IEL density (IEL/100EC) was poorly correlated with tTG, villus height, crypt depth or their ratios, and even significant findings did not show strong correlation coefficients (<0.36). The IEL density cut off scored 93% sensitivity and specificity at 24/100EC for CD. However, for NCGS the optimal sensitivity and specificity cut off was at 22IEL/ 100EC giving a sensitivity of 57% and specificity of 80% (see fig 1). The villus height was significantly shorter in CD compared to either control (p<0.001) or NCGS groups (p<0.001). Also, NCGS had short villus height than control (p<0.001). Conclusion The most specific and strongest biomarker for CD with microenteropathy is serology acting as the gold standard in this group. Villus height and crypt depth would serve as complementary tools in diagnosis of mild CD and NCGS patients. NCGS seem to have a milder morphological change compared to CD even when they present with similar Marsh scores. This study also confirms the cut off of IEL for CD with microenteropathy is similar to CD with severe enteropathy at 25 IEL/100EC.
