Summary

Helicobacter pylori is a common stomach infection causing inflammation and ulcers. Current guidelines recommend proton pump inhibitor-based triple therapy for effective H. pylori eradication, surpassing older treatments.

Background:

Helicobacter pylori is a significant cause of chronic stomach inflammation.
Infection can lead to peptic ulcers, gastric cancer, and MALT lymphoma.
Its role in nonulcer dyspepsia and NSAID gastropathy is debated.

Purpose of the Study:

To review current guidelines on H. pylori investigation and treatment.
To identify the gold standard for H. pylori eradication.
To assess the cost-effectiveness of H. pylori eradication in peptic ulcer disease.

Main Methods:

Review of European and upcoming Canadian guidelines.
Comparison of classical triple therapy with newer proton pump inhibitor-based regimens.
Analysis of eradication rates and clinical recommendations.

Main Results:

Proton pump inhibitor (PPI) plus two antibiotics is superior to classical triple therapy (BMT).
A one-week PPI-based triple therapy regimen is the current standard.
Canadian single-antibiotic PPI regimens show lower eradication rates.

Conclusions:

Eradication of H. pylori in peptic ulcer disease is clinically beneficial and cost-effective.
PPI-based triple therapy is the recommended first-line treatment.
Retreatment with PPI plus BMT is advised if initial therapy fails, per European guidelines.
