[KYOTO CONSENSUS - THE NEW ETIOLOGICAL CLASSIFICATION OF CHRONIC GASTRITIS AND ITS DISCUSSION]

Area of Science:

• Gastroenterology
• Microbiology

Background:

• The etiology of chronic gastritis is complex, with ongoing debate regarding the role of Helicobacter pylori.
• New etiological classifications aim to refine understanding, but require validation against current evidence.

Purpose of the Study:

• To critically evaluate the new etiological classification of chronic gastritis.
• To investigate the role of Helicobacter pylori and gastric microflora in chronic gastritis development.
• To explore the contribution of alcoholic and chemical factors to gastritis and gastric cancer.

Main Methods:

• Analysis of recent data on Helicobacter pylori infection.
• Investigation of gastric microflora composition, concentration, and pathogenic properties (e.g., urease activity).
• Review of evidence concerning alcoholic and chemical gastritis and their link to stomach cancer.

Main Results:

• Helicobacter pylori's role in chronic gastritis is re-evaluated within the new classification framework.
• Gastric microflora analysis reveals varying frequencies, concentrations, and pathogenic potentials contributing to gastritis.
• Alcoholic and chemical gastritis are discussed as potential etiological factors, with implications for stomach cancer risk.

Conclusions:

• The study highlights inconsistencies between current chronic gastritis classifications and evidence-based medicine principles.
• Further research is needed to reconcile etiological classifications with the multifactorial nature of chronic gastritis.
• The findings emphasize the need for a comprehensive approach considering microbial, chemical, and lifestyle factors in gastritis and gastric cancer.
