Gastric exocrine and endocrine cell morphology under prolonged acid inhibition therapy: results of a 5‐year follow‐up in the LOTUS trial

Abstract

Antral gastritis improved in H. pylori-infected GERD patients after 5 years on esomeprazole, with little change in laparoscopic antireflux surgery patients, who acted as a control. Despite a continued proliferative drive on enterochromaffin-like cells during esomeprazole treatment, no dysplastic or neoplastic lesions were found and no safety concerns were raised. NCT 00251927.
