Clinical significance of changes of flora in the upper digestive tract.

Dysbiosis does not necessarily mean disease. Typical clinical picture of disease caused by metabolic activity of dysbiotic microflora is the microbial over-growth syndrome. We studied case histories of 434 patients without consideration of their basic illnesses and correlated them with types of dysbioses of duodenal juice. 55% of 314 patients with gastrointestinal disorders revealed a dysbiosis. A dysbiosis could also be found in up to 64% of pancreatic diseases, whereas intestinal dysfunctions and chronic inflammatory diseases usually show normal colonization. These cases express alteration of milieu conditions and disturbed interorganic connections. We only treated cases with objective pathological findings, obtaining best results with chemotherapeutic treatment of dysbioses with only one species.
