Brief Summary

Helicobacter pylori (H. pylori) infection has been associated with a development of atrophic gastritis and intestinal metaplasia. H. pylori related atrophic gastritis and intestinal metaplasia have been regarded as pre-malignant lesion. However, the role of H. pylori eradication treatment in the reversibility of atrophic gastritis and intestinal metaplasia has not been clearly defined. The aim of the present study was to investigate the relationship between H. pylori eradication and the reversibility of atrophic gastritis and intestinal metaplasia in Korean patients.

Outcome Measures

Primary Outcomes (1)

  • The improvement of Atrophic Gastritis and Intestinal metaplasia score

    The improvement of Atrophic Gastritis and Intestinal metaplasia was defined as improvement of score compared with baseline. The histological features of the gastric mucosa were recorded using updated Sydney system scores, that is, 0 = none, 1 = mild, 2 = moderate, and 3 = marked.(Am J Surg Pathol 1996;20:1161-81.) Outcome measure will be done annually (per 1 year), final follow-up is 2019

    per 1 year

Study Arms (2)

H. pylori eradication group

Patients who have had H. pylori infection. After diagnosis of H. pylori infection, the patients who subsequently received successful H. pylori eradication treatment according to appropriate indication.

Control Group

Patients who still have H. pylori infection. The patients of control group do not have successful H. pylori eradication result or do not received eradication treatment for any reason.
