“…The presently applied Sydney System combines microscopic evaluation with the topography and aetiology of the inflammation. In addition, information about the stage and extent of a chronic inflammatory process can be provided by two other evaluation systems known as operative link for gastritis assessment (OLGA) and operative link on gastric intestinal metaplasia (OLGIM) [1, 2]. …”

IntroductionMany clinicians consider chronic gastritis to be equivalent to Helicobacter pylori infection. However, it is known that there are numerous other causes of the condition.AimDetermination of the incidence of gastritis in patients with dyspepsia referred for diagnostic endoscopy of the upper part of the digestive tract, identification of the parts of the stomach most frequently affected by the inflammation, as well as the impact of an insufficient number of collected samples on the correct diagnosis.Material and methodsUpper gastrointestinal endoscopy due to dyspepsia was performed in 110 patients. In the course of gastroscopy two biopsy specimens were collected for histopathological examination and towards H. pylori infection from the lesser and greater curvature in the antrum 3 cm from the pyloric sphincter, in the body – 4 cm proximally to the stomach angular incisure on the lesser curvature, and in the middle of the greater curvature, as well as in the subcardiac region on the side of the lesser and greater curvature.ResultsIn patients with dyspepsia H. pylori-negative chronic gastritis is more common than gastritis with accompanying H. pylori infection. Collection of too small a number of biopsy specimens results in failure to detect inflammatory changes and/or H. pylori infection, which may be limited to one part of the stomach. Biopsy specimens of gastric mucosa should be collected in compliance with the assumptions of the Sydney System. Helicobacter pylori infection in people with dyspepsia is now being reported more rarely than in the past (36%).ConclusionsIn patients with dyspepsia chronic H. pylori-negative gastritis is more common than gastritis with an accompanying H. pylori infection. Helicobacter pylori infection is not always equivalent to the presence of chronic gastritis.

“…Few studies have directly compared pathologist consistency in diagnosis of gastritis or H. pylori infection [24–26]. Here, specimens were reviewed by two pathologists independently, both as a way to validate the findings, but also to understand inter-pathologist variation.…”

Helicobacter pylori infection is common among Alaska native (AN) people, however scant gastric histopathologic data is available for this population. This study aimed to characterise gastric histopathology and H. pylori infection among AN people. We enrolled AN adults undergoing upper endoscopy. Gastric biopsy samples were evaluated for pathologic changes, the presence of H. pylori, and the presence of cag pathogenicity island-positive bacteria. Of 432 persons; two persons were diagnosed with gastric adenocarcinoma, two with MALT lymphoma, 40 (10%) with ulcers, and 51 (12%) with intestinal metaplasia. Fifty-five per cent of H. pylori-positive persons had cag pathogenicity island positive bacteria. The gastric antrum had the highest prevalence of acute and chronic moderate–severe gastritis. H. pylori-positive persons were 16 and four times more likely to have moderate–severe acute gastritis and chronic gastritis (p < 0.01), respectively. An intact cag pathogenicity island positive was correlated with moderate–severe acute antral gastritis (53% vs. 31%, p = 0.0003). H. pylori-positive persons were more likely to have moderate–severe acute and chronic gastritis compared to H. pylori-negative persons. Gastritis and intestinal metaplasia were most frequently found in the gastric antrum. Intact cag pathogenicity island positive was correlated with acute antral gastritis and intestinal metaplasia.
