Abstract:
Background: Although eradication of Helicobacter pylori infection can decrease the risk of gastric cancer, the optimal regimen for treating the general population remains unclear. We report the eradication rate (intention‐to‐treat and per protocol) of a community‐based H. pylori therapy using the strategy of test, treat, retest, and re‐treat initial treatment failures. Materials and methods: In 2004, a total of 2658 residents were recruited for 13 C‐urea breath testing. Participants with positive results for infection received a standard 7‐day triple therapy (esomeprazole 40 mg once daily, amoxicillin 1 g twice daily, and clarithromycin 500 mg twice daily), and a 10‐day re‐treatment (esomeprazole 40 mg once daily, amoxicillin 1 g twice daily, and levofloxacin 500 mg once daily) if the follow‐up tests remained positive. Both H. pylori status and side‐effects were assessed 6 weeks after treatment. Results: Among 886 valid reporters, eradication rates with initial therapy were 86.9% (95% confidence interval [CI]: 84.7–89.1%) and 88.7% (95%CI: 86.5–90.9%) by intention‐to‐treat and per protocol analysis, respectively. Re‐treatment eradicated infection in 91.4% (95%CI: 86–96.8%) of 105 nonresponders. Adequate compliance was achieved in 798 (90.1%) of 886 subjects receiving the initial treatment and in all 105 re‐treated subjects. Mild side‐effects occurred in 24% of subjects. Overall intention‐to‐treat and per protocol eradication rates were 97.7% (95%CI: 96.7–98.7%) and 98.8% (95%CI: 98.5–99.3%), respectively, which were only affected by poor compliance (odds ratio, 3.3; 95%CI, 1.99–5.48; p 〈 .0001). Conclusions: A comprehensive plan using drugs in which the resistance rate is low in a population combined with the strategy of test, treat, retest, and re‐treat of needed can result in virtual eradication of H. pylori from a population. This provides a model for planning country‐ or region‐wide eradication programs.
