Giant hypertrophic gastropathy (Ménétrier's disease): pharmacologic effects on protein leakage and mucosal
Abstract:
Seven patients with giant hypertrophic gastropathy participated in a gastric intubation perfusion study to investigate the route and mechanism of protein leakage associated with this disease. All patients had gastric tight junctions wider than those in healthy controls. Acute administration of propantheline bromide reduced gastric albumin leakage (-50.7%, p less than 0.05) and concurrently decreased width of tight junctions (p less than 0.05) in all patients. Another antisecretory agent, cimetidine, had no consistent effect on protein leakage or on the width of tight junctions. Pentagastrin and bethanechol chloride increased protein loss but had no effect on the width of tight junctions. These results are consistent with the hypothesis that proteins may take a paracellular route via the tight junctions as they traverse the gastric mucosa and that this may have a cholinergic mechanism.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
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.
