title: [Morphology of gastritis and Helicobacter pylori infection].
abstract: Helicobacter pylori infection almost invariably results in chronic gastritis. The Sydney System (1990) emphasised the importance of combining topographical, morphological and etiological aspects in attempt to make clinical useful diagnosis of chronic gastritis. The aims of revised Sydney System in Houston (1994), Texas, were to improve terminology of chronic gastritis emphasising distinction between nonatrophic and atrophic gastritis, and in addition to determinate special forms of gastritis. The special forms of gastritis were described and diagnostic criteria were provided. Principles and grading of histological division of Sydney System were only slightly modified, grading being improved by the provision of a visual scale. Endoscopy and histological findings of 1062 patients from University Hospital Merkur were compared to evaluate the value of endoscopic division of Sydney System, and the modified grading proposed by Houston classification. There was no correlation between endoscopic and histological findings. Localisation of inflammatory cells was either 1) superficial or 2) diffuse in the mucosa, respectively. In Helicobacter pylori positive patients the most common finding was chronic active gastritis, and in Helicobacter pylori negative superficial and inactive chronic gastritis.
