Pepsinogen gastrin mesor ratio: a potential simple marker for gastric secretory function

|January 1, 1984
Summary
The pepsinogen/gastrin (PGI/G) ratio is a valuable marker for gastric acid-peptic secretory capacity. This ratio improves diagnostic significance for duodenal ulcers and pregnancy compared to single G or PGI levels.
Area of Science:
- Gastroenterology
- Biochemistry
Background:
- Serum gastrin (G) and pepsinogen I (PGI) levels are altered in duodenal ulcer disease and pregnancy.
- Gastrin influences gastric secretion and parietal cell mass, while PGI reflects pepsin-secreting cell capacity.
Purpose of the Study:
- To evaluate the diagnostic utility of the PGI/G ratio as a marker for gastric acid-peptic secretory capacity.
- To compare the discriminatory power of the PGI/G ratio against individual G and PGI serum levels.
Main Methods:
- Analysis of serum G and PGI levels in patients with duodenal ulcer and pregnant women.
- Calculation and comparison of the PGI/G ratio in different physiological and pathological states.
Main Results:
- Duodenal ulcer patients exhibited decreased G and increased PGI levels.
- Third-trimester pregnant women showed increased G and decreased PGI levels.
- The PGI/G ratio demonstrated a potentially discriminatory marker for gastric secreting capacity.
Conclusions:
- The PGI/G ratio offers improved diagnostic significance over single G or PGI measurements.
- This ratio serves as a reliable marker for screening and clinical assessment of gastric secretory function.
