BackgroundThe effects of acarbose add-on therapy on gut microbiota and inflammatory cytokines were investigated in Chinese patients with type 2 diabetes mellitus (DM). MethodsNinety-five DM patients were randomly allocated to two groups: 59 to Group A who received antidiabetic treatment that included acarbose 150mg/day, and 36 to Group B who received similar treatment to Group A but without acarbose. Forty-five healthy volunteers were selected as a control group. Serum concentrations of inflammatory cytokines were determined by ELISA, and the contents of 16S rDNA of gut bacteria were determined by real-time quantitative polymerase chain reaction. General linear analysis for repeated measurements was used to analyze trend differences between the two diabetic groups. ResultsAfter 4 weeks of antidiabetic treatment, the gut contents of Bifidobacterium longum and Enterococcus faecalis were significantly increased in both diabetes groups. The increase of Bifidobacterium longum (P=0.004) and the decrease of lipopolysaccharides (LPS) (P<0.001) and prothrombin activator inhibitor-1 (P=0.003) were more significant in Group A. Decreases of monocyte chemoattractant protein-1 and LPS were more significant in patients whose HbA1c decrease was 1%, but there were no significant differences in the changes of other cytokines and gut bacteria between patients with HbA1c <7% and 7%. Pearson correlation analysis showed that changes of Enterococcus faecalis were negatively correlated with LPS, while multiple linear regression analysis showed a positive correlation of Bifidobacterium longum with acarbose treatment and the high-density lipoprotein cholesterol concentration. ConclusionsAcarbose treatment can increase the content of gut Bifidobacterium longum in type 2 diabetes mellitus patients and decrease some inflammatory cytokines independently of its antihyperglycemic effects.
