Fecal Microbiome Transplantation (FMT) for Type 1 Diabetes

Not Applicable
Conditions
Type 1 Diabetes
Interventions
Biological: Fecal Microbiota Transplantation (FMT)
Registration Number
NCT04124211
Lead Sponsor
The Third Affiliated Hospital of Southern Medical University
Brief Summary

This study intends to reconstruct intestinal micro-ecology through fecal Microbiome transplantation (FMT) technology, to treat patients with type 1 diabetes, and combine intestinal Metagenomics and 16s rRNA sequencing technology to study the relevant mechanism of intestinal micro-ecology for the treatment of type 1 diabetes.

Detailed Description

Type 1 diabetes is an organ-specific autoimmune disease based on islet beta cell-specific destruction and absolute insulin deficiency. Studies on the pathogenesis of intestinal flora and type 1 diabetes have shown that as an "endocrine organ", intestinal microbes play an important role in regulating the secretion of the body. Bacteria in the intestine can not only directly synthesize hormones or hormone-like compounds, but also regulate the synthesis and secretion of corresponding hormones in the widely distributed intestinal endocrine cells, thereby participating in the regulation of various biological functions in the human body. This study uses fecal microbiome transplantation (FMT) to explore another potential treatment for type 1 diabetes.
