    Abstract:
    Duodenal ulcer patients have increased serum pepsinogen I (PGI) concentrations and an increased prevalence of Helicobacter pylori infection. We have examined the effect of eradicating the infection on PGI. In 12 duodenal ulcer patients in whom H. pylori was successfully eradicated, the median basal PGI was 90 ng/ml (range, 37-252) before treatment and fell to 74 ng/ml (28-197) 1 month after treatment (p less than 0.01). In 12 patients in whom therapy failed to eradicate the infection, the PGI was 87 ng/ml (35-128) before treatment and remained unchanged at 83 ng/ml (36-119) 1 month after treatment. In the group with successful eradication the median basal plasma gastrin was 43 ng/l (15-95) before treatment and fell to 30 ng/l (17-75) 1 month after treatment (p less than 0.003), but there was no change in the corresponding values in the group without eradication (55 ng/l; range, 25-120, and 45 ng/l; range, 5-175; p = 0.9). In conclusion, eradication of H. pylori results in a fall in PGI and plasma gastrin, and these changes are not due merely to the anti-H. pylori drugs themselves or to discontinuation of previous ulcer therapy.
