| Abstract: | AIM: Intestinal metaplasia (IM) is more often found in patients with Helicobacter pylori(H pylori) infection, while eradication of H pylori results in significant reduction in the severity and activity of chronic gastritis. We aimed to determine in patients with unsuccessful eradication of H pylori the role of various proton pump inhibitors (PPIs)having different mechanisms in the resolution of IM.METHODS: We confirmed endoscopically and pathohistologically (Sydney classification) the IM in 335 patients with gastritis before and after medication for eradication of H pylori(Maastricht Protocol 2002). H pylori infection was determined by using histology, urease test and culture. Control endoscopy and histology were done after 30 d and thereafter (within 1 year). Unsuccessful eradication was considered if only one of the three tests (histology, urease and culture) was negative after therapy protocol. We used omeprazole, pantoprazole,lansoprazole in therapy protocols (in combination with two antibiotics).RESULTS: We found no significant difference in resolution of IM by using different PPI between the groups of eradicated and noneradicated patients (P＜0.4821 and P＜0.4388,respectively).CONCLUSION: There is no significant difference in resolution of intestinal metaplasia by different proton pump inhibitors. |
