The Trend of First-Line and Second-Line Eradication Rates for Helicobacter pylori Infection in a Single Institute in Seoul / 이화의대지

ABSTRACT

OBJECTIVES: To investigate the rate of first-line eradication and the rate of second-line eradication of Helicobacter pylori (H. pylori) from 2001 to 2010 in a single institute in Seoul. METHODS: Among the 2,717 patients who received H. pylori eradication treatment from 2001 to 2010 at Ewha Womans University Mokdong Hospital, the medical records of 1,466 patients who satisfied the condition of execution of upper gastrointestinal endoscopy, positive H. pylori eradication results at 6~8 weeks after eradication therapy were reviewed retrospectively. Then the first-line and second-line eradication rates and the eradication rates according to endoscopy findings were also compared. RESULTS: The first-line eradication rate was 77% H. pylori eradication rate for the last 5 years was continuously increasing and no sign of decline was observed even for the whole 10 years. The rates of eradication related to endoscopic findings showed statistical significance (P<0.001) of 79.8% and 70.1% each for peptic ulcer and non-ulcerative gastric diseases, respectively. CONCLUSION: In this study, no decrease in tendency of first-line eradication rate could be found. In addition, the patients with the non-ulcerative gastric disease seemed to show significantly lower eradication rate. This finding suggests eradication treatment may be affected by the category of gastric diseases, and careful considerations should be taken assessing the effects and needs for the H. pylori eradication treatment.
