Effect of Gluten-free Diet on Preventing Recurrence of Gastroesophageal Reflux Disease-related Symptoms in Adult Celiac Patients with Nonerosive Reflux Disease

Background And Aim: In celiac disease (CD) the role of a gluten-free diet (GFD) on gastroesophageal reflux disease-related symptoms (GERD-rs) is unclear. The aim of this study was to establish the recurrence of GERD-rs, in CD patients with nonerosive reflux disease (NERD).

Methods: From a total of 105 adult CD patients observed, 29 who presented with the NERD form were enrolled in the study. Thirty non-CD patients with NERD were studied as controls. Recurrence of GERD-rs was clinically assessed at 6, 12, 18, and 24 months follow-up (FU) after withdrawal of initial proton-pump inhibitor (PPI) treatment for 8 weeks.

Results: GERD-rs were resolved in 25 (86.2%) CD patients and in 20 (66.7%) controls after 8 weeks of PPI treatment. In the CD group, recurrence of GERD-rs was found in five cases (20%) at 6 months but in none at 12, 18, and 24 months while in the control group recurrence was found in six of 20 controls (30%), in another six (12/20, 60%), in another three (15/20, 75%), and in another two (17/20, 85%) at 6, 12, 18, and 24 months FU respectively.

Conclusions: The present study is the first to have evaluated the effect of a GFD in the nonerosive form of GERD in CD patients, by means of clinical long-term follow-up, suggesting that GFD could be a useful approach in reducing GERD symptoms and in the prevention of recurrence.
