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 rescue regimens for H pylori eradication
The aims of this study are
1 to compare the efficacy of HDDT and BQT as rescue 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

Detailed Description:
Participants aged 20 having H pylori-positive chronic gastritis withwithout peptic ulcers duodenal or gastric ulcers will be recruited All undergo endoscopy with biopsy for rapid urease teat histology and bacterial culture before treatment Four to eight weeks after termination of treatment H pylori infection status will be examined by the 13C-urea breath test The CYP2C19 genotype of each participant will be analyzed by the polymerase chain reaction-based restriction fragment length polymerase PCR-RFLP method A computed generated random numbers sequence will be blocked into two subgroups say A and B
If the patients failed anti-H pylori therapy previously they will be invited to enter this study for evaluating the efficacy of these rescue regimens Participant who meet the inclusion criteria and do not have any one of the exclusion criteria will be randomized to receive one of the following regimens
group A- HDDT rabeprazole 20 mg qid amoxicillin 750 mg qid for 14 days
group B- BQT rabeprazole 20 mg qid tripotassium dicitrate bismuthate 300 mg qid metronidazole 250 mg qid tetracycline 500 mg qid for 10 days
All participants will be asked to complete a questionnaire and to record symptoms and drug consumption daily during the treatment period Post-treatment the participants will be followed up at the Outpatients Clinic to investigate patient adherence and adverse effect of treatment
