Actual role of pepsinogen group I in the study of upper gastrointestinal diseases.
The role of serum PG I in screening patients with chronic atrophic gastritis and gastric cancer, and in detecting peptic ulcer patients with high relapse risk, was ascertained in 276 subjects. Although not diagnostic per se, PG I was found to be under 20 micrograms/L in patients with chronic atrophic gastritis and in some gastric cancer or partially gastrectomized patients. In patients presenting with relapsing duodenal ulcer, PG I values were significantly higher than in the non-relapsing ones, but a satisfactory identification of all the duodenal ulcer patients with high relapse risk was not possible on this basis. Even the correlation between PG I and MAO was not accurate in every subject considered. These results suggest that the value of PG I is limited to assessing patients with upper gastrointestinal diseases in which a reduction of peptic secretion, and therefore of PG I in serum, is present.
