Background & Aims:
Lymphocytic gastritis is associated with celiac disease. Gastric permeability can now be assessed by a sucrose test, and intestinal permeability measured by a lactulose/mannitol test is increased in untreated celiac patients. The aim of this study was to prospectively compare gastric and intestinal permeability with histological changes of the stomach and small bowel in patients with celiac disease.
Methods:
Gastric and intestinal permeability were measured by oral or duodenal (during endoscopy) administration of a triple sugar solution containing 20 g sucrose, 10 g lactulose, and 5 g mannitol in 100 mL water in 43 adult patients with celiac disease (28 without diet) and in 30 healthy controls. Endoscopical biopsy specimens were taken from the antrum and distal duodenum and investigated for intraepithelial lymphocyte counts.
Results:
Urinary sucrose excretion decreased after duodenal administration (n = 8) as opposed to oral administration and thus measured gastric permeability in celiac disease. Gastric permeability was elevated in 60% of the celiac patients and correlated with antral intraepithelial lymphocyte counts. Intestinal permeability (measured by a lactulose/mannitol test) was also elevated in 69% of the celiac patients and correlated with duodenal intraepithelial counts.
Conclusions:
There is a high prevalence of lymphocytic gastritis in untreated celiac disease associated with elevated gastric permeability. Celiac disease seems to be a general disorder of the gastrointestinal tract associated with disturbed permeability.

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...

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,...
01:17Gastritis-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...
