Recent studies have shown that obesity is not a homogeneous condition and that there is a subgroup of people with obesity, but without metabolic disturbance. This phenotype of obesity is called “metabolically healthy obesity” (MHO) [1]. More and more data are appearing in the scientific literature, indicating that quantitative and qualitative changes in the gut microbiota (GM) can be a trigger in the development of obesity and metabolic disorders [2]. In order to study the role of GM in the development of various types of obesity, 37 patients were examined, divided into 3 groups: group 1 (n = 11) - healthy people without obesity and overweight (control), group 2 (n = 13) - patients with MHO, group 3 (n = 13) - patients with metabolically unhealthy obesity (MUHO). The basic metabolic parameters were determined for all of them and a quantitative assessment of the condition of the GM was performed using the Real-time PCR method. Results: 1. In people from the control group (group 1) in the GM, compared with formal normative indicators, the number of Lactobacillus spp., Bifidobacterium spp., B. thetaiotaomicron was reduced (p<0.05) and indicators of the total bacterial mass and Enterobacter spp./Citrobacter spp. were increased (p<0.05). 2. In subjects with MHO (group 2), GM changes similar to group 1 were observed. However, in comparison to group 1, Klebsiella spp. and Proteus spp. were recorded in feces in quantities exceeding the formal regulatory. In patients with MUHO (group 3), in addition to changes detected in group 2, C. difficile was found in feces, as well as a significant (p <0.05) decrease in F. prausnitzii and an increase (p <0.05) in the detection frequency of banal E.coli, as well as the more diverse composition of the microbiota. Thus, the data obtained as a result of a pilot study certainly indicate changes in the GM in people with different phenotypes of obesity and in healthy ones. Further study of the GM in patients with various types of obesity, but in a larger groups, is required. Reference: 1) Phillips C.M.
