Abstract:
AIM: To investigate the effect of eradication of Helicobacter pylori using combination therapy with low-dose omeprazole and clarithromycin on the healing and recurrence of peptide ulcers. PATIENTS AND METHODS: We studied 60 patients with active duodenal ulcers and 60 with gastric ulcers who were H. pylori-positive by the rapid urease test and a histological examination of antral biopsy specimens. The eradication method used was a combination of omeprazole (20 mg a day) and clarithromycin (400 mg twice a day). The patients were followed up for 24 months after the end of the treatment. H. pylori infection and the ulcer stage were investigated by endoscopy every 6 months. We assessed the relationship between H. pylori infection, ulcer healing to a white scar and ulcer recurrence after combination therapy. RESULTS: H. pylori was eradicated in 23 out of 120 patients (22%), with suppression in 101 out of 120 patients (84%). The rate of ulcer healing to a white scar 6 months after treatment was significantly higher and the ulcer recurrence rate within 2 years after treatment was significantly lower in patients with H. pylori suppression or eradication than in those continuously positive for the organism. CONCLUSIONS: These results suggest that not only the eradication but also the suppression of H. pylori may improve ulcer healing and reduce the rate of relapse.
