Bismuth Based Quadruple Therapy, Helicobacter Pylori Infection, Potassium-Competitive Acid Blocker, Proton Pump Inhibitor, Treatment
Conditions
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
Patients will a 10-day course of bismuth, metronidazole, tetracycline four times daily, and vonoprazan 20 mg twice daily.
Patients will receive a 10-day course of bismuth, metronidazole, tetracycline four times daily, and rabeprazole 20 mg twice daily.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Helicobacter pylori eradication | 2 weeks after proton pump inhibitor | Helicobacter pylori eradication rate will be recorded. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Adverse drug reactions | 2 weeks after proton pump inhibitor | Adverse drug reactions will be recorded. |
| Patient adherence | 2 weeks after proton pump inhibitor | Adherence will be assessed by asking patients to return used packaging and by questioning. |
| Degree of patient satisfaction | 2 weeks after proton pump inhibitor | Degree of patient satisfaction will be assessed on a 5-point Likert scale patient satisfaction (1, extremely dissatisfied; 2, unsatisfied; 3, neutral; 4, satisfied; 5, extremely satisfied) |
