OBJECTIVE: This study was performed to assess the affects of age, sex, and Helicobacter pylori status on pepsinogen testing for atrophic gastritis and to establish the clinical implications of pepsinogen test results and H. pylori serology in a Korean population presenting for a health check-up. METHODS: Serum pepsinogen (PG) I and PG II, and H. pylori IgG were measured in 1485 adults. The PG values were analyzed based on age, sex, and H. pylori status, and the cutoff value for atrophic gastritis was determined. RESULTS: Serum PG I (sPGI) and sPGII were higher in H. pylori positive than in H. pylori negative individuals (sPGI, 56.3 vs. 42.2 microg/l, P<0.001; sPGII, 17.5 vs. 8.0 microg/l, P<0.001). The PG I/II ratio was lower in H. pylori positive than in H. pylori negative individuals (3.7 vs. 6.0, P<0.001). The sPGII and PG I/II ratio had a positive (r=0.132, P<0.001) and negative correlation with age (r=-0.229, P<0.001), respectively. Men had a higher sPGI (54.7 microg/l) than did women (48.4 microg/l) (P<0.001) but the PG I/II ratio was not statistically different and neither the atrophic gastritis. The PG I/II cutoff value for atrophic gastritis was 6.0 for H. pylori negative and 3.0 for H. pylori positive individuals. sPGI and sPGII were, however, not specific for atrophic gastritis. CONCLUSION: The H. pylori IgG status, age, and sex were associated with the serum PG levels. To increase the efficacy of the PG I/II ratio for the detection of atrophic gastritis, the cutoff value of the PG I/II ratio should be stratified according to the H. pylori IgG status in the Korean population presenting for a health check-up.
