简要总结
The purpose of this study is to assess efficacy of 10-day antimicrobial susceptibility test guided triple therapy for the first-line treatment of Helicobacter pylori infection, then comparing it with 14-day empirical tailored therapy to tell which one has a better performance in both efficacy and safety.
详细描述
Helicobacter pylori(H.pylori), which infects about 50% of the global population, has been recognized as a main risk factor of multiple gastric pathologies, especially non-cardiac gastric cancer. Strongly evidence supports that H.pylori eradication is an effective approach to reduce the incidence of those pathologies. Antimicrobial susceptibility test can pick out sensitive drugs to kill Helicobacter pylori, and reduce secondary drug resistance. But, there is a lack of high quality RCT to compare its efficacy with empirical regimen in the first-line treatment.
Our study aims to assess the efficacy of 10-day antimicrobial susceptibility test guided triple therapy for the first-line treatment of Helicobacter pylori infection. Comparing this regimen with 14-day Empirical Tailored Therapy to tell which one is better in clinic practice. We also want to find whether the 10-day antimicrobial susceptibility test guided triple therapy has less intestinal dysbacteriosis with a shorter duration.

研究组 & 干预措施
Antimicrobial susceptibility testing guided therapy
Patients in this group will receive a 10-day triple therapy for the Helicobacter pylori eradication. The regimen contains one proton pump inhibitor and two sensitive antibiotics determined by AST. The susceptibility of amoxicillin, clarithromycin, metronidazole, tinidazole, levofloxacin, furazolidone and tetracycline will be evaluated.
Drugs: 1.one proton pump inhibitor: lansoprazole 30mg bid for 10d 2.two sensitive antibiotics: amoxicillin 1000mg bid for 10d, clarithromycin 500mg bid for 10d, metronidazole 500mg tid for 10d, tinidazole 500mg tid for 10d, levofloxacin 500mg qd for 10d, furazolidone 100mg bid for 10d, tetracycline 750mg bid for 10d.
干预措施: two sensitive antibiotics(amoxicillin, clarithromycin, metronidazole, tinidazole, levofloxacin, furazolidone and tetracycline) (Drug)

干预措施: one proton pump inhibitor(PPI) (Drug)
Empirical tailored therapy
Patients in this group will receive a 14-day bismuth-based quadruple therapy for the H.pylori eradication. The regimen contains one PPI, Colloidal Bismuth Pectin and two antibiotics based on personal medication history. If the patient has taken clarithromycin, roxithromycin and azithromycin for less than 2 weeks before, he will be treated with amoxicillin and clarithromycin. Otherwise, he will be treated with amoxicillin and furazolidone.
