[Microecological aspects of small intestinal bacterial overgrowth syndrome].
Small intestinal bacterial overgrowth syndrome (SIBOS) means chronic recurrent diarrhea with malabsorption, intoxication and increased risk of endogenous infection. This syndrome are accompanied by increase of overall bacterial burden in biotope >10(5) CFU/ml in adults and >10(4) CFU/ml in children, emergence of different species of enterobacteria, bacteroides, clostridia and fusobacteria et al. in small intestine. Such characteristics of the syndrome allow to consider it as syndrome of disturbances of intestinal microflora (dysbacteriosis). Microecological changes are accompanied by B12 vitamin deficiency anemia, hypovitaminosis, protein deficiency, translocation of bacteria and their toxins from intestine in blood, emergence of endotoxinemia and possible generalization of infection. SIBOS is diagnosed by concentration of hydrogen in expiratory flow (lactulosa load test) or by bacteriological study of aspirate from proximal part of small intestine. Complex treatment includes containing lacto- and bifidobacteria probiotics and, in more severe cases, antimicrobial agents (vancomycine, metronidazole, aminoglycosides, amoxicillin clavulanate, tetracycline, and cephalosporines of 2nd generation) with following correction of disturbed microbiocenosis by different probiotics.
