O-GlcNac Modified Proteomics Study of the Maturation of Hemodialysis Arteriovenous

Completed

• Conditions: Arteriovenous Fistula Occlusion
• Interventions: Other: No intervention

• Registration Number: NCT05832476
• Lead Sponsor: National Taiwan University Hospital

Brief Summary

We divided into three parts to carry out. Firstly, evidence the pre-existing fibrosis in vein of AVF failure patients. investigation of expression, the role, and the mechanism by which the identified O-GlcNAac proteins promote, maturation of AV fistula. Finally, ddress and compare the proteomics differentiation between failure and maturation of AVF patients.

Detailed Description

End stage renal disease (ESRD) patients requires hemodialysis to maintain bloodstream functions. Before the hemodialysis, the patients requires a long-term vascular access, which best choice is Arteriovenous fistulas (AVF). However, 1/3 of patients were failure in AVF maturation, and it is still unknown. Our preliminary data have shown that pre-exisiting fibrosis in vein of AVF failure. Here, we will investigate whether pre-existing fibrosis of vein is asssociated with circulating fibrocytes in AVF failure, and further to address molecular mechanism of fibrocytes differentiation. We will divide into three parts to carry out. Firstly, evidence the pre-existing fibrosis in vein of AVF failure patients. Secondary, investigation of expression, the role, and the mechanism by which the identified O-GlcNAac proteins promote, maturation of AV fistula. Finally, address and compare the proteomics differentiation between failure and maturation of AVF patients. We hope that through this project, we can obtain signifiture molecules for precision detection and solve the current clinical unmet need.
