Characterization of the gut microbiota in Diabetes Mellitus II patients with adequate and inadequate metabolic control


Objective: The objective of this study was to characterize the composition of the gut microbiota in type 2 Diabetes Mellitus (T2DM) patients with adequate and inadequate metabolic control, and its relationship with fiber consumption.

Results: A total of 26 patients with type 2 diabetes mellitus (T2DM) were enrolled, of which 7 (26.9%) cases had an adequate metabolic control (HbA1c <7%) and 19 (73.1%) an inadequate metabolic control (HbA1c ≥ 7%). It was observed that among patients with controlled T2DM, 2 (28.6%) cases presented good intake of fiber and 5 (71.4%) cases a regular intake. In contrast, in patients with uncontrolled T2DM, 13 (68.4%) patients reported a regular intake and 6 (31.6%) a poor intake. In relation to the identification of the gut microbiota, both groups presented a similar characterization. Although not significant, the groups showed a slight difference on the frequency of bacteria genus identified. The most frequently identified bacteria in controlled and uncontrolled T2DM patients were Prevotella (71.4% vs 52.6%), followed by Firmicutes (71.4% vs 42.1%), Proteobacteria (71.4% vs 36.8%) and Bacteroidetes (57.1% vs 37.8%). On the other hand, Fusobacterium, Actinobacteria were not identified in either of the two groups of study.
