The use of <i>E. faecium</i> probiotic and autoprobiotic in patients with type 2 diabetes mellitus

Abstract

BACKGROUND: Bacteria in the gastrointestinal tract regulate eating behavior and metabolic processes. A number of probiotic strains have a positive effect on glucose and insulin metabolism. A series of studies have demonstrated the effectiveness of autoprobiotic therapy in the treatment of patients with gastrointestinal diseases. The efficacy and safety of an indigenous strain of Enterococcus faecium in overweight patients with type 2 diabetes has not been studied in the past.
 AIM: To evaluate the effectiveness of products containing the probiotic strain Enterococcus faecium L3 or the indigenous strain Enterococcus faecium in patients with diabetes mellitus (DM) type 2.
 MATERIALS AND METHODS: Patients with diabetes mellitus type 2 were randomized into two groups: group of probiotic therapy with an industrial strain of Enterococcus faecium L3 (11 patients); group of autoprobiotic therapy based on an indigenous strain of Enterococcus faecium (9 patients). Therapy was for 14 days. Before and 10-14 days after the end of therapy, anthropometric parameters were assessed; psychometric testing was carried out; biochemical parameters of blood serum were studied. The intestinal microbiota was studied by real-time polymerase chain reaction.
 RESULTS: Probiotic therapy based on Enterococcus faecium L3 and autoprobiotic therapy based on indigenous Enterococcus faecium had no significant effect on glucose metabolism in patients with type 2 DM. In the Enterococcus faecium L3 group and the group of indigenous Enterococcus faecium there was a significant decrease in gastroenterological complaints on scales of the GSRS questionnaire. Patients in both groups showed a statistically significant decrease in the total bacterial mass, an increase in the quantitative content of Lactobacillus spp., a decrease in the population of Bifidobacterium spp. and Bacteroides thetaiotaomicron.
 CONCLUSIONS: The probiotic strain Enterococcus faecium L3 and the indigenous Enterococcus faecium do not have a significant effect on the metabolism of glucose and insulin, while they contribute to a similar change in the component composition of the microbiota and a decrease in the severity of gastroenterological complaints.
