Combination therapy with mucosal protective agent for the eradication of Helicobacter pylori.

OBJECTIVE

To investigate the effect of plaunotol in combination with proton-pump inhibitors on Helicobacter pylori eradication in patients with gastric ulcer.

PATIENTS AND

METHODS

We studied 65 H. pylori-positive gastric ulcer patients. They were randomly assigned to five treatment groups: omeprazole (group I, n = 8), lansoprazole (group II, n = 13), lansoprazole+plaunotol (group III, n = 12), lansoprazole+clarithromycin (group IV, n = 16) and lansoprazole+plaunotol+clarithromycin (group V, n = 16). Ulcer status was diagnosed by endoscopy and H. pylori status by culture, histology, a urease test and a urea breath test at baseline, and after 8 and 12 weeks. The clearance and eradication rates were compared in each group.

RESULTS

The healing rates in groups I-V were 100, 92, 100, 100 and 100%, respectively; clearance rates were 0, 23, 42, 50 and 75%, respectively; and eradication rates were 0, 0, 8, 38 and 69%, respectively.

CONCLUSION

Combination therapy with plaunotol is efficacious for the eradication of H. pylori in gastric ulcer patients.
