Usefulness of videoduodenoscopy and vital dye staining as indicators of mucosal atrophy of celiac disease: assessment of interobserver agreement

Vital dye staining and cell lineage tracers were used to mark superficial cells of early Ambystoma mexicanum gastrulae. Superficial marks placed between the equator and the blastopore, on the dorsal midline, stained notochord, whereas marks or injections made at similar animal—vegetal levels but 90° to either side of the dorsal midline were later found in somitic mesoderm. Notochord marks remained on the dorsal surface of the archenteron throughout gastrulation, though they became elongate and narrow by the morphogenetic movements of extension and convergence. Marked somitic mesoderm disappeared from the superficial epithelial layer soon after passing over the blastoporal lip and could not be found on the archenteron surface. A possible mechanism for this de-epithelialization is proposed on the basis of correlated SEM. The significance of a method of gastrulation so distinctly different from that of certain other amphibians is discussed in terms of amphibian phylogeny.

The Mean

Abstract Background Celiac disease (1) mostly diagnosed base on positive serology and duodenal mucosal atrophy, but some patients have negative serology and their diagnosis have some limitation, it delay in diagnosis likely accompanied a poor prognosis and high risk of developing complications of CD. The aim of this study was determent clinical profile of patients with Seronegative CD (SNCD). Methods in this retrospective study, 1115+8 patients, that evaluated for CD with mucosal atrophy included between 2010 to2020. All patients with IgA deficiency other IgG based serology for diagnosis of celiac was done and if these antibodies were negative consider as possible SNCD. If they had positive DQ2-DQ8, and clinical symptoms or had positive challenge test after12 months of GFD were considered as SNCD. Results of total 1115 patients 27 (2.4%) had seronegative mucosal atrophy of duodenum and diagnosed as a SNCD (96.2% marsh3), the mean age and BMI in SNCD patients were significantly higher than other CD patients (p<0.05). Conclusion The prevalence of SNCD was 2.4% that likely related to over weighting, so clinicians should be considered high possible of seronegative CD in patients with over weighting and mucosal atrophy of duodenum.
