Abstract:
Duodenal ulcer is a common disease. It has always been said that it results from an imbalance between aggressive forces (HC1 and pepsin) and defensive forces that act on the mucosa. More attention has traditionally been paid to acid and relative less interest to pepsin. Two types of pepsinogen have been recognized as precursors of peptic activity in the lumen. Pepsinogen I has been more frequently implicated in ulcerogenesis. The aim of this review is to consider the different current pathophysiologic and clinical aspects, and to take into account its importance as a predictive and genetic marker in duodenal ulcer disease, which is always a challenge in the daily practice of gastroenterologists.

In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds to M3...

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 III: Clinical Manifestations and Diagnostic Studies
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
