The prevalence of Helicobacter pylori (H. pylori)-associated ulcers is declining, but NSAID-induced ulcers are rising. H. pylori eradication may prevent NSAID complications and benefit some non-ulcer dyspepsia cases.
Area of Science:
- Gastroenterology
- Microbiology
Background:
- Peptic ulcer disease (PUD) epidemiology is shifting, with decreasing Helicobacter pylori (H. pylori)-associated ulcers and increasing NSAID-induced and H. pylori-negative idiopathic ulcers.
- The incidence of bleeding ulcers remains stable, but H. pylori virulence factors and host genetics are implicated in duodenal ulcer risk.
Purpose of the Study:
- To analyze the evolving landscape of peptic ulcer disease.
- To examine the role of H. pylori in PUD, NSAID complications, GERD, and dyspepsia.
Main Methods:
- Literature review and analysis of epidemiological trends in peptic ulcer disease.
- Examination of H. pylori virulence factors and host genetic associations with ulcer development.
- Assessment of H. pylori eradication impact on NSAID complications, GERD, and non-ulcer dyspepsia.
Main Results:
- H. pylori-associated ulcers are decreasing, while NSAID-induced and idiopathic ulcers are increasing.
- H. pylori eradication may prevent NSAID complications and is recommended before long-term PPI treatment in GERD patients to prevent gastric atrophy.
- A test-and-treat strategy for H. pylori in dyspepsia is more cost-effective than endoscopy.
Conclusions:
- The management of peptic ulcer disease requires adapting to changing etiological factors.
- H. pylori eradication strategies should be considered for specific patient groups, including those on NSAIDs or with dyspepsia, and in GERD patients prior to PPI therapy.

Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
