Relationship between Helicobacter pylori and atrophic gastritis.

OBJECTIVES
To investigate the relationship between Helicobacter pylori and atrophic gastritis.


DESIGN AND METHODS
The extent of atrophic gastritis was assessed endoscopically in 97 non-ulcer patients, and their H. pylori status was assessed by enzyme-linked immunosorbent assay.


RESULTS
The prevalence of H. pylori infection was greatest in the early stages of atrophic gastritis. Small numbers of H. pylori-negative patients were identified at different stages during the extension of atrophic gastritis.


CONCLUSIONS
H. pylori infection precedes the extension of atrophic gastritis, and a minority of patients with atrophic gastritis may never have been infected with H. pylori.
