Serum Pepsinogen After H. Pylori Eradication

Completed
Conditions
Helicobacter Pylori Eradication
Registration Number
NCT03924375
Lead Sponsor
Soonchunhyang University Hospital
Brief Summary

Helicobacter pylori has been recognized as a major pathogen in gastric carcinogenesis. Current guidelines recommend the H. pylori "test-and-treat" strategy for the purpose of primary and secondary gastric cancer prevention. Considering the "point of no return" theory, however, H. pylori eradication cannot reduce the risk of gastric cancer in subjects with gastric atrophy and intestinal metaplasia. The intragastric hypoacidic environment is associated with the risk of intestinal-type gastric cancer development. Recently, the secretory ability of the stomach can be measured using the serum pepsinogen (PG) assay.

Detailed Description

This study aimed to evaluate the change of serum PGs after H. pylori eradication success and identify the optimal timing of eradication.
