Brief summary

This study aims to compare the eradication rate, safety, and patient adherence between potassium-competitive acid blockers (P-CABs) and proton pump inhibitor-based bismuth quadruple therapy in patients with Helicobacter pylori infection.

Detailed description

Helicobacter pylori (H. pylori) is a spiral-shaped, Gram-negative bacterium that colonizes the stomach lining and is considered one of the most prevalent chronic infections globally. Bismuth-based quadruple therapy (proton pump inhibitor, bismuth, metronidazole, and tetracycline) is considered an effective alternative in cases of antibiotic resistance. This regimen achieves high eradication rates, even in areas with dual clarithromycin and metronidazole resistance. Potassium-competitive acid blockers (P-CABs), such as vonoprazan, provide rapid, consistent, and strong acid suppression regardless of the CYP2C19 genotype.

Interventions

DRUGPotassium-Competitive Acid Blocker

Patients will a 10-day course of bismuth, metronidazole, tetracycline four times daily, and vonoprazan 20 mg twice daily.

DRUGProton Pump Inhibitor

Patients will receive a 10-day course of bismuth, metronidazole, tetracycline four times daily, and rabeprazole 20 mg twice daily.

Design outcomes

Primary

MeasureTime frameDescription
Helicobacter pylori eradication2 weeks after proton pump inhibitorHelicobacter pylori eradication rate will be recorded.
