Aliment Pharmacol Ther 2010; 32: 83–96 Summary Background Changes in gastric histology associated with long‐term maintenance therapy with lansoprazole for erosive oesophagitis have not been well described. Aim To evaluate the effect on gastric histology of long‐term dose‐titrated lansoprazole administered as maintenance therapy for up to 82 months in patients with erosive oesophagitis. Methods Sequential gastric biopsy specimens were obtained for evaluation of histological changes and Helicobacter pylori infection status. Results Active and chronic inflammation improved from baseline to final visit in a majority of patients receiving long‐term therapy with lansoprazole, irrespective of baseline H. pylori infection status. Reductions in active inflammation in the gastric body and antrum were seen in 53% (17/32) and 67% (20/30) of H. pylori ‐positive patients, respectively, and in 88% (7/8) and 86% (12/14) of H. pylori ‐negative patients, respectively. Reductions in chronic inflammation in the gastric body and antrum were seen in 38% (12/32) and 47% (15/32) of H. pylori ‐positive patients, respectively, and in 58% (70/121) and 57% (68/120) of H. pylori ‐negative patients, respectively. No clinically meaningful increases in hyperplasia, dysplasia, neoplasia, intestinal metaplasia or atrophy were observed during the follow‐up period. Conclusions Lansoprazole administered as maintenance therapy for up to 6 years in patients with erosive oesophagitis demonstrated gastric mucosal safety and was well tolerated.
