Influence of Ulcer Stage on Helicobacter pylori Eradication Rate / 胃肠病学

ABSTRACT

Background: Helicobacter pylori (Hp) infection is associated with a variety of gastrointestinal diseases.Studies have shown that Hp eradication rate may be affected by the disease type and stage of disease progression.Aims: To investigate the influence of endoscopic ulcer stage on Hp eradication rate.Methods: A total of 423 peptic ulcer (PU) patients with Hp infection from January 2015 to July 2016 at the People's Hospital of Xinjiang Uygur Autonomous Region were enrolled.Of them,133 were gastric ulcer (GU) and 255 were duodenal ulcer (DU).A 14-day bismuth quadruple therapy was given for Hp eradication,and the eradication rates were analyzed with the endoscopic ulcer stage.Univariate analysis was conducted to identify factors influencing the eradication rate.Results: There was no significant difference in Hp eradication rates between GU and DU groups (82.7％ vs.83.9％,P>0.05).The eradication rates according to endoscopic ulcer stage were significantly different in GU group (active stage vs.inactive stage 89.0％ vs.75.0％,P＜0.05);but in DU group,the eradication rate in active stage was similar to that in inactive stage (85.6％ vs.83.0％,P>0.05).Univariate analysis revealed that ulcer stage was correlated with the success rate of eradication;the eradication rate in active stage was significantly higher than that in inactive stage (87.8％ vs.80.3％,P＜0.05).Conclusions: Endoscopic ulcer stage is correlated with the Hp eradication rate in PU,especially GU patients.Hp eradication therapy performed in patients with active PU could yield a higher eradication rate.
