We aimed to assess the correlation between clinical findings, serology, endoscopic findings, and histology in children diagnosed with celiac disease. Medical records of children diagnosed with celiac disease (2010–2017) at the Schneider Children’s Hospital were reviewed retrospectively. Correlation between serologic measures anti-tissue transglutaminase (anti-tTG)/anti-endomysial antibodies (EMA) and other variables including mucosal damage, endoscopic findings (scalloping of duodenal folds), and clinical findings (abdominal pain, diarrhea, and anemia) was assessed. Out of 686 patients, 432 patients fulfilled the inclusion criteria (females 262, 61%; median age 6.0; interquartile range 4.0–9.0 years). Distribution of histopathology findings was Marsh IIIa 4%, Marsh IIIb 25%, and Marsh IIIc 71% with 313 (73%) patients having anti-tTG titer of ≥ 10 times the upper normal limit. Anti-tTG titer (but not EMA) positively correlated with Marsh grades, scalloping of duodenal folds and anemia. Anti-tTG ≥ 10 times the upper normal limit was associated with Marsh IIIc changes with an adjusted odds ratio of 4.5 (95% confidence interval, 1.7–12.1). Diarrhea and abdominal pain were not associated with serologic, endoscopic, or histologic markers of disease severity. Conclusion : Anti-tTG titers correlated with macroscopic and microscopic mucosal damage, with anemia but not with diarrhea or abdominal pain in children with celiac disease. What is Known: • Tissue transglutaminase antibody titers were shown to correlate with the degree of mucosal damage in patients with celiac disease . • There is a limited evidence regarding the association of celiac serologies with endoscopic and clinical measures . What is New: • Higher titers of tissue transglutaminase but not anti-endomysial antibodies are associated with more severe histologic and endoscopic damage and with the presence of anemia . • Symptoms do not correlate with the severity of mucosal damage such as scalloping of duodenal folds and histopathology changes according to Marsh classification or with serologic markers .
