Brief Summary
Up to now, there is few randomized, large scale study prospectively and simultaneously comparing the efficacy, adverse effects and patient adherence of high-dose dual therapy (HDDT) and bismuth-containing quadruple therapy (BQT) as 1st-line regimens for H. pylori eradication. The aims of this study are:
- 1.to compare the efficacy of HDDT, and BQT as 1st-line regimen in H. pylori eradication;
- 2.to compare the patient adherence and adverse effects of these treatment regimens;
- 3.to investigate factors that may influence H. pylori eradication by these treatment regimens.

The eradication rates as a measure of the efficacy of HDDT, and BQT
The eradication rates (efficacy) will be evaluated by intention-to-treat (ITT) and per-protocol (PP) analysis.
3.5 years
Secondary Outcomes (2)
Number of participants with adverse effects as a measure of safety
3.5 years
Amount of unused medication post treatment as a measure of patient adherence.
