Treatment of Peptic Ulcer Disease with Active H. pylori Infection — Treatment-Naive

This protocol addresses peptic ulcer disease in patients with confirmed, active Helicobacter pylori infection who have never received H. pylori eradication therapy and have no penicillin allergy.

Clinical scenario

Active H. pylori infection has been confirmed by a nonserological test. No prior eradication attempt has been made (treatment-naive), and antibiotic susceptibility results are not yet available. Penicillin allergy is absent.

Treatment approach

Empiric first-line eradication therapy is recommended when antibiotic susceptibility is unknown; the preferred approach involves a bismuth-based quadruple regimen, with suitable empiric alternatives available for specific patient profiles.

Treatment goals

Confirmed eradication of H. pylori infection, verified by a negative urea breath test, fecal antigen test, or biopsy-based test performed at least 4 weeks after completing therapy.
