Abstract:
This year eradication of H. pylori was applied for not only peptic ulcer but also chronic gastritis on National insurance system. However recently decrease in first line eradication rate of H. pylori using PPI/AC regimen. Certainly eradication rate after 2000 decreased in intention to treat (ITT) and per protocol(PP) compared to that before 2000. This tendency was induced by increase in CAM-resistant H. pylori. But after 2007 eradication rate decreased only in ITT, eradication rate didn't decrease in PP. That tendency was induced by bad compliance and evaluation of the eradication.

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.
Peptic Ulcer Disease IV: Management
The therapeutic approach involves ensuring adequate rest, implementing drug therapy, promoting smoking cessation, making dietary modifications, and emphasizing long-term follow-up care.
Pharmacological management
The prevailing therapy for peptic ulcers involves a combination of managing the patient's current medication...
