TTG Ab-positive patients were classified as having either potential CD with (n = 3, 16%) and without lymphocytic duodenosis (LD; n = 12, 63%), and no CD (n = 4, 21%) on human leukocyte antigen typing. There was an increase in duodenal eosinophils in patients with elevated TTG Ab (P = 0.01), which remained when patients with LD were excluded (P = 0.018). Of 19 patients with EoE and elevated TTG Ab, 5 responded to elimination diet involving exclusion of wheat, including 2 with a sole wheat trigger and TTG Ab >10× ULN that were CD-associated human leukocyte antigen-negative. Conclusions: Serum TTG Ab was elevated in almost one-quarter of our total EoE cohort, and at least 20% of these patients did not have potential CD, suggesting EoE is a heterogeneous disease with differing immune mechanisms activated in some patients. These findings also support routine esophageal biopsy during upper endoscopy in children with elevated TTG Ab.]]> Tue 11 Sep 2018 12:15:33 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38224 Mon 16 Aug 2021 15:26:47 AEST ]]>
