Type 2 diabetes mellitus is an extremely common disease that leads to the development of life-threatening complications but its pathogenesis remains poorly understood. One of the promising directions in this area is the study of disorders of gut microbiota. Literature data indicate that a number of quantitative and qualitative changes in the composition of the gut microbiota are the most important factors in the pathogenesis of type 2 diabetes mellitus. Bacteria of the genera Ruminococcus, Fusobacterium and Blautia are most involved in the pathogenesis of this disease. The participation of the gut microbiota in the pathogenesis of type 2 diabetes mellitus is due to its metabolites, which play an important role in the regulation of the permeability and integrity of the intestinal wall, the expression of specific intestinal receptors, incretin secretion, gluconeogenesis activity, chronic subclinical inflammation, and even in adipose tissue remodeling. Further in-depth study of gut microbiota disorders is promising in order to develop fundamentally new approaches to the treatment and prevention of type 2 diabetes mellitus.

AbstractA strong and expanding evidence base supports the influence of gut microbiota in human metabolism. Altered glucose homeostasis is associated with altered gut microbiota, and is clearly associated with the development of type 2 diabetes mellitus (T2DM) and associated complications. Understanding the causal association between gut microbiota and metabolic risk has the potential role of identifying susceptible individuals to allow early targeted intervention.

Abstract Gut microbiota plays an important role in the regulation of the immune system and host’s metabolism. We aimed to characterize the gut microbiota of Tunisian participants with and without diabetes. We enrolled ten participants with type 1 diabetes mellitus (T1DM), ten patients with type 2 diabetes mellitus (T2DM), and 11 subjects without diabetes. Bacteria was quantified in fecal samples by quantitative PCR (qPCR). Statistical tests and multivariate analysis were performed using RStudio program. Results showed that the proportions of Firmicutes, Akkermansia muciniphila, and Faecalibacterium prausnitzii (P≤0.041), as well as, the ratio Firmicutes/Bacteroidetes decreased in participants with T1DM compared with those without diabetes (p = 0.036). Participants with T2DM presented a reduction in the amounts of A. muciniphila and F. prausnitzii compared with those without diabetes (P≤0.036). Furthermore, A muciniphila is negatively correlated with glucose level (P=0.022) and glycated hemoglobin (HbA1c) (P=0.035). Multivariate analysis revealed that participants with diabetes formed a cluster apart compared with those without diabetes. In conclusion the gut bacteria of Tunisian participants with diabetes was altered. The gut bacterial profile, especially the distribution of A muciniphila in participants with diabetes was affected by glycemic dysregulation. The investigation of the gut microbiota may help clinicians to improve diagnosis and treatment of diabetes and its complications.
