Potassium‐Competitive Acid Blocker‐Associated Gastric Hyperplastic Polyps With Severe Bleeding: A Case Series [PDF]
DEN OpenGastric hyperplastic polyps can cause gastrointestinal bleeding, and their enlargement has been associated with long‐term acid‐suppressive therapy. Vonoprazan (VPZ), a potassium‐competitive acid blocker, provides potent acid suppression and may induce ...

The Autoimmune Gastritis Puzzle: Emerging Cellular Crosstalk and Molecular Pathways Driving Parietal Cell Loss and ECL Cell Hyperplasia [PDF]
CellsAutoimmune gastritis (AIG) is a chronic, organ-specific autoimmune disease characterized by progressive destruction of gastric parietal cells driven by autoreactive CD4+ T-cells, epithelial stress pathways, and microbial factors.

Current Medical Controversies in Zollinger–Ellison Syndrome [PDF]
BiomedicinesPurpose: Zollinger–Ellison syndrome (ZES) is the most frequent, functional, malignant pancreatic neuroendocrine tumor syndrome (pNET), which is due to ectopic secretion of gastrin by a pNET/NET (i.e., gastrinomas) resulting in severe, refractory acid ...

Hypergastrinemia in Children : A Case Report
Archives of Pediatric Gastroenterology, Hepatology, and Nutrition, 2022 Gastrin is an important hormone in the gastrointestinal system that promotes gastric acid secretion. Gastrin hormone is produced by the G-cells in the antrum of the stomach.

Revealing autoimmune gastritis: Polypoid nodule scar development after endoscopic submucosal dissection for early gastric cancer [PDF]
DEN OpenEndoscopic submucosal dissection (ESD), the standard treatment for early gastric cancer, typically results in homogeneous flat scars. However, in some cases, polypoid nodule scars (PNS) may develop, complicating the cancer recurrence assessment.

Gastroenterology Report, 2015 Gastrin is an important hormone of the digestive system, which assists gastric acid secretion. It may be pathologically elevated in conditions such as Zollinger-Ellison syndrome, or due to common medications such as proton pump inhibitors. In this review we provide an overview of the pathophysiology and medical causes of hypergastrinemia, diagnostic ...

Gastrin and the Moderate Hypergastrinemias [PDF]
International Journal of Molecular Sciences, 2021 The antral hormone gastrin potently regulates gastric acid secretion and fundic mucosal growth. Consequently, appropriate gastrin secretion and plasma concentrations are important for the early phases of digestion. This review describes as the first premise the normal biogenesis of gastrin in the antral mucosa, but also mentions the extraantral ...
