Study Details

Study Description

Brief Summary

This randomized controlled clinical trial will compare the eradication efficacy of bismuth-metronidazole triple therapy (PPI+bismuth+ metronidazole) with that of bismuth-metronidazole quadruple therapy (PPI+bismuth+ metronidazole+ amoxicillin) for Helicobacter pylori first-line treatment. The completion of this trial will expand new therapy for the treatment of Helicobacter pylori, which can not only ensure clinical efficacy, but also reduce the use of antibiotics.

Outcome Measures

Primary Outcome Measures

  1. Eradication rate of Helicobacter pylori [At least 4 weeks after completion of therapy]

    Eradication of Helicobacter pylori was defined as negative result of urea breath test (<4‰ cut-off value).

Secondary Outcome Measures

  1. Eradication rate of Helicobacter pylori metronidazole-resistant strains [At least 4 weeks after completion of therapy]

    Eradication of Helicobacter pylori was defined as negative result of urea breath test (<4‰ cut-off value). The strains with minimal inhibitory concentration (MIC) value of metronidazole >8 μg/ml were defined as resistant strains.

  2. Eradication rate of Helicobacter pylori metronidazole-susceptible strains [At least 4 weeks after completion of therapy]

    Eradication of Helicobacter pylori was defined as negative result of urea breath test (<4‰ cut-off value). The strains with metronidazole MIC value <=8 μg/ml were defined as susceptible strains.

Other Outcome Measures

  1. Adherence rate [At least 1 weeks after completion of therapy]

    Adherence was defined as poor when subjects took less than 80% of the total medication.

  2. Frequency of adverse events [At least 1 weeks after completion of therapy]

    Any possible adverse events during the 14-day treatment period were recorded.
