Особенность микробиоты толстой кишки у пациентов с разными фенотипами ожирения (пилотное исследование)

Purpose: to study the microbiota of the colon in patients with various types of obesity and in healthy people. Materials and methods: 37 people were examined (average age 39.6 ± 4.2 years) for the period 2018 – 2019. Formed 3 clinical groups. I group (n = 11) — healthy people with normal body weight (control), II group (n = 13) — patients with metabolically healthy obesity (MHO), III group (n = 13) — with obesity and metabolic disorders. In all patients, the basic metabolic parameters were studied and a quantitative assessment of the state of colon microbiocenosis was performed. Results: compared to the formal-normative quantitative indicators, the examined fecal groups I, II and III showed unidirectional changes characterized by a decrease (p < 0.05) of Lactobacillus spp., Bifi dobacterium spp., B. thetaiotaomicron and an increase (p < 0.05 ) Enterobacter spp. / Citrobacter spp. Colon microbiota changes in groups II and III are characterized by the appearance of Proteus spp. and Klebsiella spp. (9.1 % and 8.3 % respectively). C. diffi cile (8.3 %) was detected in feces only in group III and the frequency of detection of banal E. coli was increased. Th e amount of F. prausnitzii was reduced (p < 0.05) in group III compared with group 1. Conclusion: the data obtained as a result of a pilot study indicate changes in the microbiota of the colon in people with diff erent phenotypes of obesity.
