Qilu Hospital of Shandong University · NCT07285096

This study tests whether using potassium-competitive acid blockers (P-CABs) in bismuth-containing quadruple therapy works better and is safe for adults with H. pylori infection.

What this trial studies

This is a multicenter observational cohort comparing real-world outcomes of different P-CAB-based bismuth quadruple regimens for H. pylori eradication. Adult patients (18–70 years) diagnosed by urease test, urea breath test, or histology received guideline-based, physician-prescribed quadruple therapy with P-CABs and bismuth, without any experimental procedures. The study collected eradication rates and adverse event incidence and examined clinical factors linked to treatment failure. Data came from Qilu Hospital of Shandong University and collaborating regional hospitals, using routine care records and follow-up testing.

Who should consider this trial

Good fit: Adults aged 18–70 with confirmed H. pylori infection who are willing to undergo eradication therapy and can complete post-treatment follow-up are the ideal candidates.

Not a fit: People under 18 or over 70, those with incomplete medical or follow-up records, or those given non‑specified (non‑quadruple) regimens are unlikely to gain information relevant to their care from this study.

Why it matters

Potential benefit: If successful, the results could identify P-CAB-containing regimens that improve eradication rates and reduce side effects for adults with H. pylori.

How similar studies have performed: Previous clinical work, especially with the P-CAB vonoprazan, has shown improved eradication in some settings, so this study builds on existing, but not yet universal, evidence.
