Abstract:

Objective

To explore the characteristics and changes of intestinal microbiome in hemodialysis patients with type 2 diabetes mellitus based on RNA sequencing technology.

Methods

This cross-sectional study enrolled hemodialysis patients who visited the Chinese PLA General Hospital from May to December 2023. The hemodialysis patients with type 2 diabetes were divided into a type 2 diabetes group,while those matched at the same time without type 2 diabetes were divided as a control group. General information and clinical data were collected from all the enrolled patients. Fecal samples from the patients were analyzed for their microbial composition by means of high-throughput RNA sequencing techniques,exploring the differences in α diversity, β diversity, and species of intestinal microbiota between the two groups.

Results

A total of 52 hemodialysis patients were included,with 26 in the type 2 diabetes group and 26 in the control group. There was a statistically significant difference in the β diversity of intestinal microbiota between the two groups (P <0. 05), but not in the α diversity (P >0. 05). There were significant differences between the two groups in a total of 11 intestinal microbiota (linear discriminant analysis threshold 4, P <0.05). The type 2 diabetes group significantly enriched Proteobacteria, Gamma Proteobacteria, Enterobacteriaceae, Christenseniaceae, Enterobacteriaceae, and its Escherichia, while the control group significantly enriched Firmicutes, Clostridia, Eubacilli, Trichospiriceae, and its Brautzia.
