These guidelines are based on pediatric studies and suggest that high anti-tTG antibody titers are almost 100% predictive of the presence of villous atrophy on SBB [16][17][18][19][20]. In clinical practice, pediatric patients are often referred with transient non-specific symptoms and are screened for CD as part of their evaluation by anti-tTG antibodies.…”

Background: The clinical, histological, and serological spectrum of celiac disease (CD) vary widely. We aimed to examine relationships between symptoms, serum anti-tissue transglutaminase antibodies (tTG) levels, mucosal damage, and mucosal anti-tTG deposits in pediatric CD. Methods: A retrospective single-center, cohort study of children referred for endoscopy with suspected CD during 2011–2014. We retrieved the clinical data, blindly reviewed duodenal biopsies, and performed immunohistochemical staining for anti-tTG deposits. Patients were classified as monosymptomatic or polysymptomatic. Mucosal anti-tTG deposits were classified according to the location of deposits, dominant intensity, maximal intensity, and percentage of stained area. Results: Of 252 patients with confirmed CD, complete data were available for 100: 37 males in the age range 1.3–16.7 with median 4.0 years. Monosymptomatic patients (n = 54) presented at an older age than polysymptomatic patients (1.3–15.5, median 8.1 vs. 1.3–16.7, median 6.3 years, p = 0.026). Marsh 2–3c was more prevalent in polysymptomatic patients (93 vs. 78%, p = 0.028). The intensity of mucosal anti-tTG deposits correlated with serum anti-tTG levels but not with the clinical presentation. Conclusions: Multiple symptoms and high serum anti-tTG antibody levels correlated with mucosal damage in children with CD. The role of immunohistochemical staining for intestinal anti-tTG mucosal deposits in the diagnosis of borderline CD is not yet established.

“…The high values match the results from other studies that also find tTG IgA to be the most successful test together with EMA. 3,6,8,26,34,37 IgG tests. There is insufficient data about EMA IgG and tTG IgG in the selected studies to make firm conclusions.…”

Background and aim: We present a systematic review on the performance of currently available methods for serological diagnosis of celiac disease (CD) and the role of human leukocyte antigen (HLA) typing. Objective: A literature survey was conducted using PubMed, MeSH database, Web of Science as well as manual searches. Results: Tissue transglutaminase antibodies (tTG) (IgA) (tested in nine studies) show sensitivities and specificities in the range of 0.76-0.968 and 0.909-0.98, and deamidated gliadin peptide (DGP) (IgA and IgG) (tested in eight studies) show sensitivities and specificities in the range of 0.69-0.984 and 0.903-1. Endomysial antibodies (EMA) (tested in five studies) show sensitivities and specificities in the range of 0.61-0.937 and 0.98-1, respectively. Combination assays (tested in three studies) using DGP þ tTG and DGP (IgA þ IgG) show sensitivities and specificities in the range of 0.87-1 and 0.8-1, respectively. HLA DQ2/DQ8 may be necessary for the development of CD-HLA DQ2 in particular. A possible close correlation may also exist between CD and HLA-G. Conclusion: DGP and tTG for serological testing for CD show equivalent diagnostic performance. More studies with, in particular, DGP alone and in combination with tTG are necessary before a firm recommendation can be made. HLA typing to exclude CD may still be controversial. It still seems premature to diagnose celiac disease in adults based on serology alone.

“…Fewer studies checked two antibodies, mainly IgA-tTg and IgA-EMA, the latest being in 2012-13 [10][11][12][13]. Only in two Israeli studies, 5 different antibodies' levels were correlated to the mucosal damage [14,15].…”
