Abstract:
Chronic gastritis is defined as the presence of chronic mucosal inflammatory changes leading eventually to mucosal atrophy and epithelial metaplasia. It is notable for distinct causal subgroups and for patterns of histological alterations that vary in different parts of the world. By far the most important aetiological association is chronic infection by the bacillus Helicobacter pylori (Hp). The organism is a worldwide pathogen that has the highest infection rates in developing countries including Iran. In this study, samples confirmed for the diagnosis of chronic gastritis from 100 Hp-positive and 36 Hp-negative patients, were reevaluated histopathologically to determine the severity of inflammation, the presence of active gastritis, lymphoid follicle(s), glandular atrophy and intestinal metaplasia. Seventy-five percent of the samples showed mild inflammation, whilst moderate and severe inflammation was seen respectively in 24% and about 1% of the cases. Among the evaluated variables, only activity and intestinal metaplasia had statistically significant associations with Hp (p < 0.05) in this survey.

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.
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...
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,...
