Abstract:
Helicobacter pylori (H. pylori) antimicrobial resistance is an urgent, global issue. In 2017, the World Health Organization designated clarithromycin-resistant H. pylori as a high priority bacterium for antibiotic research and development. In addition to clarithromycin, resistance to metronidazole and fluoroquinolones has also increased worldwide. Recent international guidelines for management of H. pylori infection recommend bismuth or non-bismuth quadruple therapy for 14 d as a first-line treatment for H. pylori in areas of high clarithromycin and/or metronidazole resistance. Although these treatment regimens provide acceptable H. pylori eradication rates, the regimens used should not contribute to future resistance of H. pylori to antimicrobials. Moreover, these regimens can promote resistance, due to prolonged therapy with multiple antibiotics. A new strategy that can eradicate H. pylori as well as reduce the antibiotics used is required to prevent future antimicrobial resistance in H. pylori. Dual-therapy with vonoprazan and amoxicillin could be a breakthrough for H. pylori eradication in an era of growing antimicrobial resistance. This regimen may provide a satisfactory eradication rate of H. pylori and also minimize antimicrobial resistance due to single antibiotic use and the strong inhibitory effect of vonoprazan on gastric acid secretion.
Insights
Antimicrobial resistance in Helicobacter pylori (H. pylori) is a growing concern. Dual therapy with vonoprazan and amoxicillin offers a promising new strategy to effectively eradicate H. pylori while minimizing future resistance.
Area of Science:
- Microbiology
- Infectious Diseases
- Pharmacology
Background:
- Antimicrobial resistance in Helicobacter pylori (H. pylori) is a significant global health challenge.
- The World Health Organization has prioritized clarithromycin-resistant H. pylori due to increasing resistance rates worldwide.
- Current treatment guidelines recommend quadruple therapy, but concerns exist regarding the promotion of further antimicrobial resistance.
Purpose of the Study:
- To explore novel therapeutic strategies for H. pylori eradication.
- To identify treatment regimens that minimize the development of future antimicrobial resistance.
- To evaluate the potential of dual therapy with vonoprazan and amoxicillin as a breakthrough treatment.
Main Methods:
- Review of current literature on H. pylori resistance patterns and treatment guidelines.
- Analysis of the proposed dual-therapy regimen (vonoprazan and amoxicillin).
- Assessment of the impact of vonoprazan on gastric acid secretion and its potential role in enhancing eradication and reducing resistance.
Main Results:
- Increasing resistance to clarithromycin, metronidazole, and fluoroquinolones necessitates alternative H. pylori treatments.
- Quadruple therapies, while effective, may inadvertently contribute to future antimicrobial resistance.
- Dual therapy with vonoprazan and amoxicillin shows promise for satisfactory H. pylori eradication rates.
- This regimen may reduce the risk of promoting antimicrobial resistance through single antibiotic use and vonoprazan's potent acid suppression.
Conclusions:
- A new strategy is needed to combat H. pylori resistance and reduce antibiotic usage.
- Dual therapy with vonoprazan and amoxicillin presents a potential breakthrough for H. pylori eradication.
- This approach could effectively treat H. pylori infection while mitigating the development of future antimicrobial resistance.
