Abstract
BACKGROUND: The prevalence of obesity is rising dramatically worldwide. Recently, there is increasing evidence linking obesity with the functional state of the intestinal microbiota. The understanding of this relationship may provide new approaches to the treatment of obesity by manipulating the qualitative and quantitative parameters of intestinal bacterial-fungal associations.AIM: To study the features of the qualitative and quantitative composition of the colon microbiota and to evaluate associations with anamnestic, anthropometric and biochemical parameters in young obese patients.MATERIALS AND METHODS: A single-center, cross-sectional, single-stage, controlled study was conducted with the participation of 118 young people, of whom 87 were obese, and 31 people with normal body weight formed the control group. All participants underwent a biochemical blood test (total cholesterol, high-density lipoproteins, low-density lipoproteins, very low-density lipoproteins, triglycerides, uric acid, glucose, glycated hemoglobin, C-reactive protein), as well as an assessment of the state of the colon microbiota using polymerase chain reaction in real time using a set of Colonoflor-16 (premium) reagents. The Microsoft Excel 2010 and IBM SPSS Statistics 26.0 application software package was used for statistical calculations. The results were evaluated as statistically significant at a level of p<0.05.RESULTS: Analyzing the result of Colonoflor-16 premium, the discrepancy between the obtained data of the control group and the reference values of the analysis was revealed. There was a clear tendency to decrease the content of Lactobacillus spp and Bifidobacterium spp in the obesity group. In addition, in comparison with the control group (10.3%), in the obesity group Fusobacterium nucleatum significantly prevailed (37.6%) (p=0.005), with a significant decrease in the bacteria Faecalibacterium prausnitzii (p=0.030), and an increase in the bacteria Prevotella spp (p=0.029). A lot of associations of representatives of the colon microbiota with the most important anamnestic, anthropometric and biochemical parameters were revealed in young obese patients.CONCLUSION: There is a redistribution of microbiota phylotypes characterized by a decrease in apathogenic microorganisms and the appearance and increase of opportunistic and pathogenic microorganisms, which generally indicates the formation of the pro-inflammatory potential of dominants and associates in young obese patients. The presence of statistically significant correlations strongly indicates of existence of close and diverse relationships between the quantitative and qualitative parameters of the microbiota and the metabolic parameters of patients.
