Efficacies of Susceptibility-guided vs Empiric Therapy for Rescue Treatment of Helicobacter Pylori Infection
Efficacies of Susceptibility-guided vs Empiric Therapy for Rescue Treatment of Helicobacter Pylori Infection - A Prospective Randomized, Comparative Study
National Taiwan University Hospital
450 participants
Apr 11, 2022
INTERVENTIONAL
Conditions
Summary
The prevalence of H. pylori antibiotic resistance has reached an alarming level worldwide. Antibiotic stewardship programs should be urgently developed and implemented. However, H. pylori antimicrobial susceptibility testing (AST) is rarely offered, making local resistance patterns not easily available. Guideline-recommended empiric therapies (GR-ET) may no longer reliably achieve high cure rate in the era of increasing antibiotic resistance. susceptibility-guided tailored therapy (SG-TT) may be a good choice to solve this problem. The aims of this study are: 1. to compare the efficacy of SG-TT with GR-ET as rescue regimens for 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.
Eligibility
Inclusion Criteria1
- Patients, aged >= 20, having H. pylori-positive chronic gastritis with/without peptic ulcers (duodenal or gastric ulcers) will be recruited. 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.
Exclusion Criteria6
- pregnant or nursing woman;
- serious concomitant illness and malignant tumor of any kind;
- history of hypersensitivity to test drugs；
- serious bleeding during the course of this ulcer;
- previous gastric surgery;
- receiving bismuth salts, PPIs, or antibiotics in the previous month.

Interventions
Includes 5 treatment options. The priority order of treatment regimens is based on the selection principal through AST with MIC profile. 1\. clarithromycin triple therapy: include rabeprazole 20mg bid, amoxicillin 1 g bid, and clarithromycin 500 mg bid, for 14 days; or 2. levofloxacin triple therapy: include rapeprazole 20 mg bid, amoxicillin 1 g bid, and levofloxacin 500 mg bid, for 14 days; or 3. metronidazole triple therapy: include rabeprazole 20 mg bid, amoxicillin 500 mg qid, and metronidazole 250 mg qid, for 14 days; or 4. high-dose dual therapy: include rabeprazole 20 mg qid, amoxicillin 750 mg qid, for 14 days; or 5. bismuth quadruple therapy: include rabeprazole 20 mg bid, bismuth 120 mg qid, metronidazole 500 mg tid, and tetracycline 500 mg qid, for 14 days.
bismuth quadruple therapy: include rabeprazole 20 mg bid, bismuth 120 mg qid, metronidazole 500 mg tid, and tetracycline 500 mg qid, for 14 days.
