[Levels of blood pepsinogen I in the offspring of patients with duodenal ulcer].


Hyperpepsinogenemia I is a reliable subclinical marker of the genetical predisposition to suffer duodenal ulcer. For that reason we determine basal serum pepsinogen I (PG I) levels in 25 ulcerous patients and 75% of their offspring and to a control group matched by age and sex.
