Core Tip

Core Tip: Vonoprazan (VPZ)-containing triple therapies have been shown to contribute to global antimicrobial resistance, while Saccharomyces boulardii (S. boulardii) supplementation has significantly improved Helicobacter pylori eradication rates and decreased adverse events. This study revealed that the VPZ and amoxicillin dual regimen with S. boulardii supplementation is safe and effective H. pylori rescue therapy, regardless of the number of prior treatment failures. Acceptable eradication rates (> 90%) were achieved in patients with resistance to clarithromycin, metronidazole, and levofloxacin. However, the regimen may need to be adjusted for patients with anxiety.
