The Alteration of Gut Microbiota and Analysis of Related Factors in Newly Diagnosed Type 2 Diabetes Patients

Recruiting

• Conditions: Type 2 Diabetes

• Registration Number: NCT05752851
• Lead Sponsor: Nanjing First Hospital, Nanjing Medical University

Brief Summary

This Study aims to compare the characteristics of gut microbiota between the newly diagnosed T2DM and healthy subjects, and analysis the related clinical indicators that may affect the composition of gut microbiota.

Detailed Description

Previous studies have shown that gut microbiota imbalance is closely related to a variety of diseases, such as inflammatory bowel diseases (IBD), colorectal cancer (CRC), Alzheimer's disease (AD) and cardiovascular diseases. In recent years, more and more studies have found that gut microbiota plays an important role in chronic metabolic diseases such as obesity, fatty liver and diabetes. gut microbiota disorder may lead to insulin resistance，pancreatic islets injury and disorder of glycolipid metabolism through multiple metabolic pathways such as endotoxin, short chain fatty acids, bile acids, amino acids, promote the occurrence and development of T2DM. At present, there are relatively few population-based studies to assess the relationship between gut microbiota and diabetes, and the results are inconsistent or even contradictory, which may be due to the influence of the research population, disease status, diet, drugs and even detection technology. Therefore, the purpose of this study is to explore the difference of intestinal microbial characteristics between the initially diagnosed T2DM and the control group by using 16S rRNA gene sequencing analysis technology, so as to increase the understanding of the possible relationship between T2DM and intestinal microbiota, and provide theoretical support and direction guidance for the future biological treatment of diabetes.
