Influence of Microbiota-modulating Agents on Gut Flora in Community Patients with Diabetic Nephropathy
Abstract
Background Imbalanced gut flora caused by changes in gut microecological structure and diversity plays an important role in the interaction between diabetes and chronic kidney disease. Rational application of probiotics, prebiotics and other microbiota-modulating agents is contributive to the improvement of gut microbial flora environment and chronic inflammation, as well as the delay of deterioration of renal function in patients with diabetic nephropathy (DN) . Objective To understand the effect of probiotics, a microbiota-modulating agent, administered based on gut flora status in patients with DN. Methods Participants were selected from Shanghai Yinhang Community Health Center by use of stratified random sampling in 2019, including 115 patients with DN were randomly divided into control group (57 with usual treatment) and treatment group (58 with treatment with microbiota-modulating agents) . Laboratory test indices and intestinal bacterial culture results were compared between the two groups after eight weeks of treatment to assess the effect of microbiota-modulating agents on improving gut flora in DN. Results Among 115 patients with DN, there were 28 males and 87 females, the mean age was (62.9±10.0) years, and the duration of diabetic nephropathy was (14.3±7.1) years. There were no significant differences in the proportion of males, mean age, body mass index, proportion of early DN, and duration of DN between DN patients with usual treatment and those with microbiota-modulating agents treatment (P>0.05) . Compared with DN patients with usual treatment, DN patients with microbiota-modulating agents treatment had decreased levels of glucose, triglyceride, blood urea nitrogen, serum creatinine, albumin to creatinine ratio, Cystatin C, C-reactive protein, interleukin-1β, and tumor necrosis factor-α, and increased levels of high-density lipoprotein and estimated glomerular filtration rate after treatment (P<0.05) . Moreover, DN patients with microbiota-modulating agents treatment showed lower numbers of Enterococcus (Z=16.482, P<0.001) and Enterobacter (Z=5.138, P<0.001) colonies, and higher numbers of Bifidobacterium (Z=2.470, P=0.014) , and Lactobacillus (Z=8.384, P<0.001) colonies after treatment. Conclusion The number of Enterococcus and Enterobacter colonies decreased and that of Bifidobacterium and Lactobacillus colonies increased in DN patients after treatment with microbiota-modulating agents, indicating that these agents could improve the gut flora.
