[Atrophic gastritis as a pre-cancer gastric condition: a new view of the old problem]
Abstract:
The aim of the work was to study the relationship between structural changes in gastric mucosa affected by atrophic gastritis and inflammation associated with Hp infection. Endoscopic examination and NBI-visualization were used to assess distribution and severity of inflammation in 500 patients with different gastric pathologies. Histological material was studied to detect Hp. Structural changes of metaplastic type most frequently occurred in patients with atrophic gastritis (72 of 81, 88.9%), surface and erosive gastritis (13 or 3.5% and 16 or 14.3% respectively), p < 0.001. Hp infection and inflammatory-destructive changes showed no apparent trends. Mucosal changes characteristic of atrophy were only rarely accompanied by marked inflammation (14.8%) and were either mild (21%) or moderately severe (64.2%). It suggests that atrophy of gastric mucosa should be regarded as independent condition while the term atrophic gastritis should be used only in case of association between atrophy and inflammation confirmed by microscopic studies.

Gastritis II: Pathophysiology
Gastritis-I: Introduction and Types
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...
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...
Gastritis III: Clinical Manifestations and Management
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...
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 to M3...
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.
