Abstract:
Helicobacter pylori infection in children. Clinical manifestations are not specific in the course of H. pylori infection in children and in most cases the infection is asymptomatic. The initial diagnosis is based on upper gastrointestinal endoscopy with biopsy-based methods (culture, PCR, histology and rapid urease test). Treatment should be based on the results of the antibiotic (particularly clarithromycin) susceptibility testing of the isolated strains (antibiogram and/or PCR) with a good therapeutic adherence more than 90%. Finally, according to the last pediatric recommendations the treatment duration is 14 days for the triple therapy (proton pump inhibitor + two antibiotics).

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.
Pathophysiology of Peptic Ulcer Disease: Injurious Factors
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...
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.
