描述
Inclusion Criteria:
The patients who proved a failure of 1st eradication of H. pylori with Proton pump inhibitor based triple therapy (PPI bid + amoxacillin 1g b.i.d + Clarithromycin 500 mg b.i.d) or sequential therapy (initial 5-day therapy with a combination of PPI b.i.d and amoxicillin 1g b.i.d, followed by 5 days of PPI b.i.d., clarithromycin 500mg b.i.d., and metronidazole 500mg t.i.d) following three methods
- positive rapid urease test (CLOtest)

- Male and female Korean Adult (Aged ≥ 18 years)
Exclusion Criteria:
- Patients who received two or more eradication therapy for H. pylori infection
- H. pylori eradication failure because of poor compliance
- the administration of antibiotics or the consumption of bismuth salts within 4 weeks or the administration of a proton pump inhibitor (PPI) within 2 weeks
- Advanced gastric cancer or other malignancy
- Abnormal liver function or liver cirrhosis
- Abnormal renal function or chronic kidney disease
- Other severe concurrent diseases
- Previous allergic reactions to the study drugs

干预/治疗 |
---|---|
实验性的:14 day bismuth based quadruple therapy (PBMT) group
Proton pump inhibitor (PPI) regular dose b.i.d., tripotassium dicitrate bismuthate 300 mg q.i.d.
(three tablets at 30 min before meals and one tablet at 2 hours after dinner), metronidazole 500 mg t.i.d., and tetracycline 500 mg q.i.d

Rescue therapy using 14 day PBMT regimen [Proton pump inhibitor (PPI) regular dose b.i.d., tripotassium dicitrate bismuthate 300 mg q.i.d.
(three tablets at 30 min before meals and one tablet at 2 hours after dinner), metronidazole 500 mg t.i.d., and tetracycline 500 mg q.i.d]
|
实验性的:14 day Moxifloxacin containing triple therapy (MEA) group
PPI regular dose b.i.d., moxifloxacin 400 mg q.d., and amoxicillin 1g b.i.d.
|
Rescue therapy using 14 day MEA regimen (PPI regular dose b.i.d., moxifloxacin 400 mg q.d., and amoxicillin 1g b.i.d.)
|
有源比较器:14 day tailored therapy group
based on H. pylori culture and antimicrobial sensitivity, select the 2nd rescue regimen between 14 days of bismuth-based quadruple therapy or 14 days moxifloxacin-containing triple therapy according to antibiotics susceptibility.

Antral and body biopsy specimens were evaluated separately.
Organisms were identified as H. pylori by Gram staining, colony morphology, and positive oxidase, catalase, and urease reactions.
Minimum inhibitory concentrations (MICs) were determined by the agar dilution method.
Amoxicillin (Sigma Chemical Co., St. Louis, Mo.), clarithromycin (Abbott Laboratories, Abbott Park, Ill.), metronidazole (Sigma), tetracycline (Sigma) and moxifloxacin (Sigma) for the H. pylori isolates were examined by use of the serial twofold agar dilution method and the reference of susceptibility testing was according to the recommendations of the Clinical and Laboratory Standards Institute [amoxicillin (AMC), MIC ≥ 0.5 μg / ml; clarithromycin (CLA), MIC > 1.0 μ g / ml; metronidazole (MET), MIC > 8 μ g / ml; tetracycline (TC), MIC > 4 μ g / ml; and moxifloxacin (MOX), MIC > 1 μ g / ml).
