Abstract

Background:

The eradication rate of Helicobacter pylori (H. pylori) infection might be affected by the degree of inflammation of gastric mucosa represented by the endoscopic stage of peptic ulcer disease (PUD). The aims of this study were to evaluate the eradication rates of H. pylori infection according to the endoscopic stage of PUD and to document whether early eradication in the active stage could yield a higher eradication rate in patients with peptic ulcer bleeding (PUB).

Materials and Methods:

A total of 1,177 patients with PUD (380 gastric ulcer, 710 duodenal ulcer, and 87 combined ulcer) who received proton-pump inhibitor (PPI)-based triple therapy were included, and the eradication rates were compared by ulcer stage. Univariate and multivariate analyses were conducted to identify factors influencing eradication rate. In PUB, the eradication rates between the early eradication group (≤7 days) and the late eradication group (>7 days) were compared.

Results:

The eradication rates according to endoscopic stage were significantly different in gastric ulcer (active vs healing vs scarring; 84.8% vs 82.7% vs 70.6%, p = .014, respectively), but there were no significant differences in duodenal ulcer (active vs healing vs scarring; 87.6% vs 80.9%% vs 80.9% p = .169, respectively). In multivariate analyses, active ulcer as well as age younger than 50 was a significantly independent predictor of successful eradication (Odds ratio; 2.799, 95% CI; 1.659–4.723, p = .0001). The eradication rate of the early eradication group was significantly higher than the late eradication group in PUB (89.2% vs 71.9%, 95% CI; 1.265–8.269, p = .011).

Conclusions:

There was a significant difference in the eradication rate according to the endoscopic stage of gastric ulcer. Active ulcer was an independent predictor of successful eradication. Furthermore, early H. pylori eradication should be considered in patients with PUB to yield a higher eradication rate.
