Abstract
BACKGROUND

New markers are needed to improve the effectiveness of serological screening for atrophic gastritis.

AIM

To develop a cost-effective method for serological screening of atrophic gastritis with a high level of sensitivity.

METHODS

Of the 169 patients with atrophic gastritis, selected by the visual endoscopic Kimura-Takemoto method, 165 showed histological mucosal atrophy using the updated Kimura-Takemoto method. All 169 patients were examined for postprandial levels of gastrin-17 (G17) and pepsinogen-1 (PG1) using GastroPanel® (Biohit Plc, Helsinki, Finland).

RESULTS

We used the histological standard of five biopsies of the gastric mucosa, in accordance with the Kimura-Takemoto classification system to assess the sensitivity of G17 in detecting gastric mucosal atrophy. We also compared the morpho-functional relationships between the detected histological degree of gastric mucosal atrophy and the serological levels of G17 and PG1, as the markers of atrophic gastritis. The sensitivity of postprandial G17 was 62.2% for serological levels of G17 (range: 0-4 pmol/L) and 100% for serological G17 (range: 0-10 pmol/L) for the detection of monofocal severe atrophic gastritis. No strong correlation was found between the levels of PG1 and degree of histological atrophy determined by the Kimura-Takemoto classification system to identify the severity of mucosal atrophy of the gastric corpus. In the presented clinical case of a 63-year-old man with multifocal atrophic gastritis, there is a pronounced positive long-term dynamics of the serological marker of atrophy - postprandial G17, after five months of rennet replacement therapy.

CONCLUSION

Serological screening of multifocal atrophic gastritis by assessment of postprandial G17 is a cost-effective method with high sensitivity. Postprandial G17 is an earlier marker of regression of atrophic gastritis than a morphological examination of a gastric biopsy in accordance with the Sydney system. Therefore, postprandial G17 is recommended for dynamic monitoring of atrophic gastritis after treatment.

Core Tip: A new assessment of serological markers of atrophic gastritis has been developed and confirmed with application of the updated Kimura-Takemoto morphological classification system. Serological markers of atrophic gastritis in this new interpretation of the classification system can more accurately detect atrophy of the gastric mucosa and complementarily increase the effectiveness of previous technologies for serological screening of precancerous changes in the stomach. Ultimately, this new model of serological screening is highly sensitive for detecting atrophic gastritis across mild, moderate and severe degrees of disease progression.
