BLEPHARITIS AND HELICOBACTER-ASSOCIATED GASTRODUODENAL DISEASES (REVIEW).

The aim of the study was to find the relationship between the inflammatory process on the eyelids (blepharitis) and Helicobascter pylori infection. The data of numerous studies are analyzed, which give grounds to suggest a possible pathogenetic or mediated role of H. pylori infection in the development and course of inflammatory eye diseases. Fundamental in these studies are the release of harmful compounds in the exhaled air of patients with H. pylori, such as ammonia, hydrogen nitrate and hydrogen cyanide, the restoration of impression cytology after H. Pylori eradication, the presence of H. pylori in the lacrimal fluid. In this regard, the authors conclude that there are three main possible pathogenetic mechanisms for the association between H. Pylori infection and blepharitis: chronic inflammation, endothelial dysfunction, and oxidative stress.
