Background: To compare the efficacy and tolerability of minocycline vs. tetracycline in bismuth-containing quadruple therapy for Helicobacter pylori (H. pylori) rescue treatment.

Methods: This study was a multi-center, randomized-controlled, non-inferiority trial. Refractory H. pylori-infected subjects with multiple treatment-failure were randomly (1:1) allocated to receive 14-day therapy with esomeprazole 20 mg b.i.d, bismuth 220 mg b.i.d, plus metronidazole 400 mg q.i.d and minocycline 100 mg b.i.d (minocycline group) or tetracycline 500 mg q.i.d (tetracycline group). Primary outcome was H. pylori eradication rate evaluated by C-urea breath test at least 6 weeks after the end of treatment. Antibiotic resistance was determined using E test method.

Results: Three hundred and sixty-eight subjects were randomized. The eradication rates in minocycline group and tetracycline group were 88.0% (162/184, 95% CI 83.3-92.8%) and 88.6% (163/184, 95% CI 83.9-93.2%) in intention-to-treat analysis, 98.0% (149/152, 95% CI 95.8-100%) and 97.4% (150/154, 95% CI 94.9-99.9%) in per-protocol analysis, 93.1% (162/174, 95% CI 89.3-96.9%) and 93.1% (163/175, 95% CI 89.4-96.9%) in modified intention-to-treat analysis. Minocycline, tetracycline and metronidazole resistance rates were 0.7%, 1.4% and 89.6%, respectively. Non-inferiority of minocycline was confirmed (P < 0.025). Metronidazole resistance did not affect the efficacy of either therapy. The two therapies exhibited comparable frequencies of adverse events (55.4% vs. 53.3%); almost half of them were mild. Dizziness was the most common adverse events in the minocycline group.

Conclusions: Minocycline can be an alternative for tetracycline in bismuth-containing quadruple therapy for H. pylori empirical rescue treatment, irrespective of metronidazole resistance. However, relatively high incidence of adverse events in both regimens should be emphasized.

Physical liver injury is an acute and potentially serious adverse event that may result in acute liver failure or even death. Diagnosis is often challenging. Minocycline, a semi-synthetic second-generation tetracycline, has high fat solubility and good tissue permeability.

Article Synopsis
  • RamA is a crucial regulator in bacteria, enhancing resistance to tetracycline-class antibiotics by activating the operon responsible for multidrug resistance.
  • The deletion of RamA leads to significantly reduced transcription levels of this operon, while restoring RamA reinstates normal function.
  • The study highlights RamA's role in bacterial membrane stability and suggests potential pathways for developing new antimicrobial treatments against resistant strains.

When bacteria are tetracycline- or doxycycline-resistant, the ability of these bacteria to be susceptible to the other tetracyclines is not well defined. Consequently, gaining knowledge about the ability to infer Enterobacterales susceptibility to minocycline and third-generation tetracycline antibiotics from surrogates is vital. In this study, we show that tigecycline may be a reasonable surrogate from which clinicians can infer omadacycline and eravacycline susceptibilities, even in the presence of doxycycline and tetracycline resistance.

Background: Leprosy (Hansen's disease) is an infectious disease most common in resource-limited countries caused by the acid-fast bacilli Mycobacterium leprae and Mycobacterium lepromatosis that frequently affects the skin and peripheral nerves. Prompt diagnosis and treatment with multidrug therapy is crucial to reduce disease transmission and sequelae, which include nerve function impairment, ocular injury, and stigmatizing physical deformities. Traditional treatment of multibacillary leprosy consists of 12-24 months of multidrug therapy with dapsone, rifampin, and clofazimine.
