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

April 16, 2023 updated by: National Taiwan University Hospital
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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

Age of 20 and older adult patients, and preoperatively clinical and ultrasound assessment of the arm vessels are fisible for the creation of a native HDAVF that include:the augmented diameters of the veins is > 2.0 mm and the diameter of the radial artery is> 2.0 mm. Besides, there is no obvious stenosis of vessels in the forearm.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The diameter of each passage of the passage vein (forearm head vein) of the arterial and venous access within three months
Time Frame: Postoperative Three months
Comparison of the various methods to achieve within three months the checkpoint path diameter increase rate (two time points measurement difference).
Postoperative Three months

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
