Brief Summary

Current guidelines have recommended classical bismuth-containing quadruple therapy including proton-pump inhibitor, bismuth, tetracycline, metronidazole as the empirical rescue therapy. However, tetracycline is clinically unavailable in China and the high frequency of adverse events of bismuth quadruple therapy often result in poor compliance, which limited the applicability of this recommendation. We previously showed that the efficacy of bismuth-containing quadruple therapy with minocycline and metronidazole was not inferior to classical bismuth quadruple therapy for refractory H. pylori infection, though also accompanied with high occurrence of adverse events.This study aimed to evaluate the efficacy and tolerability of four different regimens with minocycline and metronidazole compared to classical bismuth quadruple therapy for H. pylori rescue treatment in a real-world setting.

Outcome Measures

Primary Outcomes (1)

  • Helicobacter pylori eradication rate

    Six weeks after completion of therapy, H. pylori eradication was assessed by ¹³C-urea breath test. Eradication was defined as negative result from urea breath test (\<4‰) (4‰ as the cutoff value).

    Six weeks after completion of therapy

Secondary Outcomes (2)

  • Rate of adverse effects

    Within six weeks after completion of therapy

  • Compliance rate

    Within six weeks after completion of therapy

Study Population

All patients who failed at least two courses of H. pylori treatment containing clarithromycin, nitroimidazoles, fluoroquinolones, and/or amoxicillin, and received 14-day tetracycline/minocycline, metronidazole-containing bismuth quadruple therapy were identified. Patients with the following criteria were excluded: (1) naive to H. pylori treatment; (2) under 18 or over 80 years; (3) history of gastrectomy; (4) administration of antibiotics, bismuth, acid suppressants, or Chinese herb medicine in the preceding 12 weeks; (5) severe systemic diseases or malignancy.

You may qualify if:

  • Confirmed H. pylori infection and with previous treatment failure

You may not qualify if:

  • subjects naive to H. pylori treatment,
  • history of gastrectomy
  • pregnant or lactating women
  • severe systemic diseases or malignancy
  • administration of antibiotics, bismuth, antisecretory drugs, or Chinese herb medicine in the preceding 12 weeks
