Summary

The goal of this clinical trial is to learn if the 14-day susceptibility-guided bismuth quadruple therapy works to treat multiple drug resistant Helicobacter pylori (H. pylori) in adults. It will also learn about the adverse effects of bismuth quadruple therapy. The main questions it aims to answer are:

* Does 14-day susceptibility-guided bismuth quadruple therapy higher the eradication rate?
* What medical problems do participants have when taking 14-day susceptibility-guided bismuth quadruple? Researchers will record 14-day susceptibility-guided bismuth quadruple to see if 14-day susceptibility-guided bismuth quadruple works to treat multiple drug resistant H. pylori.

Participants will:

* Take susceptibility-guided bismuth quadruple every day for 14 days
* Visit the clinic once 4-6 weeks for checkups and tests
* Keep a diary of their symptoms during taking susceptibility-guided bismuth quadruple

Conditions

  • Helicobacter Pylori
  • Drug Resistance, Multiple

Interventions

DRUG

Bismuth-based susceptibility-guided treatment

The investigators design four regimes for H. pylori eradication and participants receive one of the regimens based on susceptibility test. The four regimens are PBAT for those with both amoxicillin and tetracycline susceptible H. pylori; PBAM for those with amoxicillin susceptible but tetracycline resistant H. pylori; PBMT for those with amoxicillin resistant but tetracycline susceptible H. pylori; PBMR for those with both amoxicillin and tetracycline resistant H. pylori. A is amoxicillin (1000 mg thrice daily), B is colloidal bismuth subcitrate (120 mg thrice daily), M is metronidazole (500 mg thrice daily), P is a proton pump inhibitor, i.e., esomeprazole (40 mg twice daily), R is rifabutin (150 mg twice daily), and T is tetracycline (500 mg thrice daily). The treatment duration is 14 days for all regimens.
