[Topical problems of chronic gastritis].

The authors propose the definition of chronic gastritis with a brief overview of the history of investigation of this diseases and its prevalence with special reference to (1) the bacterial profile and its role in the development of infectious and inflammatory process in gastric mucosa, (2) the modern state of and new trends in the classification of chronic gastritis including their advantages and disadvantages, (3) the relationship between chronic gastritis and functional gastroduodenal dyspepsia syndrome. It is concluded that mucous microflora plays an important factor in the development ofpathology but H.pylori is not its predominant component. Modern classifications of chronic gastritis provide a basis for a deeper insight into evolution of chronic gastritis and its transformation into cancer. The diagnosis of ‘chronic gastritis with functional gastroduodenal dyspepsia syndrome‘ is invalid.
