NCT05718609

Brief Summary

This study aims to evaluate the efficacy and safety of 14-day quadruple therapy based on fecal molecular antimicrobial susceptibility tests for the first-line eradication of H. pylori infection, thus, providing more evidence to inform the value of fecal antimicrobial susceptibility tests in the first-line treatment of H. pylori infection.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Helicobacter pylori Eradication Rate

    Helicobacter pylori Eradication will be determined by 13C-urea breath test or 14C-urea breath test six to eight weeks after completion of the medication.

    Six to eight weeks after completion of the medication

Secondary Outcomes (2)

  • Rate of Adverse Drug Reaction(ADR)

    Within 7 days after completion of therapy

  • Compliance Rate

    Within 7 days after completion of therapy

Study Arms (3)

Amoxicillin- and Clarithromycin-based BQT

ACTIVE COMPARATOR

rabeprazole 10mg bid, amoxicillin 1g bid, clarithromycin 500mg bid, colloidal bismuth 200mg bid for 14 days

Drug: RabeprazoleDrug: Colloidal Bismuth Pectin GranulesDrug: AmoxicillinDrug: Clarithromycin

Clarithromycin medication history-based BQT

EXPERIMENTAL

The clarithromycin medication history will be asked before the treatment and the therapy will be performed as follows: with clarithromycin medication history: rabeprazole 10mg bid, amoxicillin 1g bid, furazolidone 100mg bid, colloidal bismuth 200mg bid for 14 days; without clarithromycin medication history: rabeprazole 10mg bid, amoxicillin 1g bid, clarithromycin 500mg bid, colloidal bismuth 200mg bid for 14 days.

Drug: RabeprazoleDrug: Colloidal Bismuth Pectin GranulesDrug: AmoxicillinDrug: FurazolidoneDrug: Clarithromycin

Antimicrobial susceptibility tests-based BQT

EXPERIMENTAL

Fecal molecular biology antimicrobial susceptibility tests will be performed before the treatment. The susceptibility of clarithromycin will be evaluated. The treatment regimen will be chosen according to the results of the antimicrobial susceptibility tests as follows: clarithromycin-sensitive: rabeprazole 10mg bid, amoxicillin 1g bid, clarithromycin 500mg bid, colloidal bismuth 200mg bid for 14 days; clarithromycin-resistant: rabeprazole 10mg bid, amoxicillin 1g bid, furazolidone 100mg bid, colloidal bismuth 200mg bid for 14 days.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Participants enrolled should meet the following criteria: (1) Participants aged 18-65 with no history of eradication treatment; (2) diagnosed as H. pylori infection by one or more of the following methodologies: gastric biopsy using histochemical staining, tissue culture, the 14C-urea breath test (UBT), the 13C-UBT, and/or fecal antigen; (3) were requested to undergo an endoscopy before the eradication treatment if they have alarm symptoms, a family history of gastric cancer or age over 40 years old without undergoing an endoscopy before; and (4) voluntarily participated in the clinical trial and have signed the informed consent.
