Outcome Measures

Primary Outcomes (1)

  • Eradication rates

    Eradication of H. pylori is measured 1 month after the therapy

Study Arms (2)

23S rRNA wt

EXPERIMENTAL

As the 23S rRNA mutation guided selection of antimicrobial agent, patients infected with strains without mutation of 23S rRNA are assigned to this arm. In this arm, they are treated with vonoprazan 20 mg bid, amoxicillin 750 mg bid and clarithromycin 200 mg bid for 1 week for the eradication of H. pylori.

Drug: Eradication of H. pylori

23S rRNA mutation

EXPERIMENTAL

As the 23S rRNA mutation guided selection of antimicrobial agent, patients infected with strains with mutation of 23S rRNA are assigned to this arm. In this arm, they are treated with vonoprazan 20 mg bid, amoxicillin 750 mg bid and metronidazole 250 mg bid for 1 week for the eradication of H. pylori,

Drug: Eradication of H. pylori

Interventions

For the eradication of H. pylori, patients diagnosed to be infected with strain with mutation of 23S rRNA, their H. pylori strains are considered to be resistant to clarithromycin. Then, they are treated with vonoprazan 40 mg, metronidazole 500 mg and amoxicillin 1500 mg for 1 week. Patients diagnosed to be infected with strain without mutation of 23S rRNA, their H. pylori strains are considered to be resistant to clarithromycin. Then, they are treated with vonoprazan 40 mg, clarithromycin 400 mg and amoxicillin 1500 mg for 1 week.
