Gastric functional status (with determination of PGI, G17, PGII, and PGI/PGII ratio) according to response rate to PPI therapy, classified according to elevation of G17 levels.
| Gastric Functional Status | ||||
|---|---|---|---|---|
|
PG-I (μg/L)
Mean ± DS |
G-17 (pmol/L)
Mean ± DS |
PG-II (pmol/L)
Mean ± DS |
PGI/PGII Ratio | |
| Total | 139.1 ± 97.3 | 11.7 ± 21.1 | 12.8 ± 10.7 | 12.4 ± 5.1 |
| Adequate response G-17 > 7 | 193.9 ± 120.8 | 21.8 ± 17.5 | 18.2 ± 13.6 | 12.6 ± 5.5 |
| Low response G-17 1-7 | 127.1 ± 68.5 | 3.1 ± 1.73 | 11.1 ± 8.5 | 12.9 ± 4.6 |
| No response G-17 < 1 | 91.2 ± 40.9 | 0.38 ± 0.29 | 7.52 ± 3.8 | 12.9 ± 3.9 |
| CAG | 17.0 ± 16.7 | 73.7 ± 54.2 | 8.6 ± 4.4 | 1.95 ± 1.8 |
CAG: chronic atrophic gastritis; G17: gastrin 17; PG-I: pepsinogen I; PG-II: pepsinogen II.
