Summary

Effective gastric and duodenal ulcer treatment depends on etiology. H. pylori ulcers require one-week eradication therapy, while NSAID ulcers need potent acid inhibitors and potential relapse prophylaxis.

Area of Science:

  • Gastroenterology
  • Internal Medicine
  • Pharmacology

Background:

  • Gastric and duodenal ulcers have varied etiologies, primarily Helicobacter pylori (H. pylori) infection and NSAID use.
  • Understanding the underlying cause is crucial for selecting appropriate and effective treatment strategies.

Purpose of the Study:

  • To outline evidence-based treatment guidelines for gastric and duodenal ulcers based on their etiology.
  • To differentiate treatment approaches for H. pylori-positive ulcers versus NSAID-induced ulcers.
  • To discuss strategies for preventing ulcer relapse.

Main Methods:

  • Review of current medical literature and treatment guidelines for peptic ulcer disease.
  • Analysis of therapeutic options including H. pylori eradication, acid suppression, and prophylactic agents.
  • Evaluation of diagnostic methods for H. pylori detection and treatment success monitoring.

Main Results:

  • H. pylori-positive ulcers without NSAID use are effectively treated with a one-week triple therapy (acid inhibitor + two antibiotics), with success confirmed by C13-urea breath test.
  • NSAID-induced ulcers without H. pylori require 4-6 weeks of potent acid inhibition (preferably PPIs).
  • Prophylaxis with Misoprostol or potentially PPIs is recommended if NSAID use continues post-treatment to prevent relapse, as H. pylori eradication does not prevent NSAID ulcer recurrence.

Conclusions:

  • Treatment selection for gastric and duodenal ulcers must be guided by etiology (H. pylori vs. NSAID).
  • H. pylori eradication is key for H. pylori-positive ulcers, while acid inhibition and relapse prophylaxis are vital for NSAID-induced ulcers.
  • Accurate diagnosis, including ruling out other causes and ensuring reliable H. pylori testing, is essential for successful management.
