Chronic gastritis is one of the most frequent gastric diseases. The morphometry in diagnostic of chronic gastritis can as appear to be a potentially significant tool. The evaluation of the histoarchitectural structure of the gastric mucosa and quantification of the various neuroendocrine cells develop the new objective methods to describe changes caused by chronic gastritis. The development of ...

Gastritis represent a state of inflammation, irritation, or erosion of the stomach lining which may occur suddenly (acute) or gradually (chronic). Generally there is no universally accepted classification of gastritis and early classification was based mainly on the morphology, but recently pathogenic mechanisms have also been incorporated. The gastric mucosa is continuously exposed to many nox...

BACKGROUND This study conducted in Northeastern Brazil, evaluated the prevalence of H. pylori infection and the presence of gastritis in HIV-infected patients. METHODS There were included 113 HIV-positive and 141 age-matched HIV-negative patients, who underwent upper gastrointestinal endoscopy for dyspeptic symptoms. H. pylori status was evaluated by urease test and histology. RESULTS The p...

A 46-year-old man had chronic granulomatous gastritis characterized by giant gastric folds with noncaseating epithelioid granulomas including giant cells in the corpus. No definite etiologic factors were detected. Histology and the rapid urease test indicated that H. pylori was present in both the antrum and corpus. The granulomatous gastritis with giant gastric folds improved after H. pylori e...

The genotypes of Helicobacter pylori flaA, cagA, vacA, and iceA were determined for DNA isolated from patients with chronic gastritis or peptic ulcer in eastern Taiwan. The vacA gene encoding the s1a subtype was found to predominate in peptic ulcer patients, and the iceA1 genotype was associated with chronic gastritis. cagA and flaA genes were not found to be associated with these types of dise...

AIMS The spectrum of microscopic lesions resulting from the chronic use of non-steroidal anti-inflammatory drugs (NSAIDs), known as chemical gastritis, remains unclear, and the variable prevalence reported in different studies makes this issue a matter of lively debate. The aim of this study was to evaluate the prevalence and importance of chemical gastritis in patients regularly taking NSAIDs....
