Abstract

Background: Celiac disease (CD) is a gluten-related immunological disorder resulting in inflammatory enteropathy. Aims: We assessed a stool marker of intestinal inflammation, the HMGB1 protein, in children with CD on a gluten free diet (GFD) at baseline and at follow up (FU). Methods: Thirty-nine children were investigated at diagnosis and at FU. Traditional serum markers of CD (anti-transglutaminase and anti-endomysial antibodies) and faecal HMGB1 (by enzyme-linked immunosorbent assay and immunoblotting) were tested. Results: There was a marked increase at baseline in both serum anti-transglutaminase IgA (anti-tTGAs) and faecal HMGB1; the latter being undetectable in controls. A strong correlation occurred between the two markers. At 12-month FU in 24 patients on GFD, HMGB1 decreased in all subjects, yet still being detectable in six children: high anti-tTGAs where evident in three, while the three with normal anti-tTGAs were complaining of intestinal symptoms and reported a low GFD adherence. Conclusions: Faecal HMGB1 is a valuable marker of intestinal inflammation and may have a role in complementing serology in the management of CD children. Future studies including larger patient cohorts and small bowel mucosa histology will be designed to assess the relationship between faecal HMGB1 levels and duodeno-jejunal histopathology. © 2018 Editrice Gastroenterologica Italiana S.r.l.
