The DATY, LAE and NLH places in CNBD INCB024360 concentration and DYS nosology structure has been established. In second step (part 2 with addition 361 healthy subjects) analytical, explanation, follow –up, case control (comparison) studies was conducted for optimize diagnosis, and to reveal new mucosa structural peculiarities, molecules regulate tight junctions status and biomarkers to the mucosa structural changes. Methods: Routine examination signs of DATY, LAE and NLH in adults and children

have been investigated and analyzed. Zoom and NBI endoscopy performed with Immunohistochemistry and Immunofluorescence: monoclonal antibodies to CD3 (for intraepithelial lymphocytosis -IEL) and to claudins 2,3,4, and 7 (CLU), MG-132 datasheet for tight junctions status) in biopsies, and expression of tissue transglutaminase (tTGA) and CLU-2, -3, -4, -7, -15 have been studied in normal and DATY mucosa. Images were assessed quantitative evaluation of Positivity by analyzing Program “Image Scope” v. 9.0.19.1516. As biomarkers investigated in blood: –

AGA-IgA, AGA-IgG, tTGA-IgA, AdeGA-IgA, AdeGA-IgG, IgA, citrullin (CTR), threonin (THR), taurine (TAU), bacterial LPS, CLU-3. Results: DATY Thiamet G is one of the leading reasons of the CNBD (11,1% (95%CI = 8, 7–13,9) in adults and the most presented as celiac disease (CD) (85,7%, 95%CI = 42,1–99,5). CD is associated: decrease in epithelial expression of CLU-2, -3, -4, -7; the first time, reversible increase in expression of tissue tTGA and CLU-15 and decrease in expression of CLU-2, -3, -4, -7 in intestinal mucosa of CD. IEL not specific for CD, and cut of 54/100 increasing sensitivity. DATY association with

disproportion in blood CTR, THR, TAU, and LPS. LAE and NLH more often have not any specific symptoms. Conclusion: Atrophy, lymphangiectasia, nodular lymphoid hyperplasia of the small intestine mucosa associated with villous structural changes and the tight junction status with reflection some biomarker in blood.
