About this study

The timing for arteriovenous fistula (AVF) creation and its effect on target organs in patients with chronic renal failure will be investigated by multicenter prospective cohort. Lower estimated glomerular filtration rate (eGFR) patients (eGFR<10ml/min 1.73m2 for patients without diabetic kidney disease, and eGFR<15ml/min 1.73m2 for diabetic kidney disease) and higher eGFR patients (eGFR 10-15ml/min 1.73m2 for patients without diabetic kidney disease, and eGFR 15-20ml/min 1.73m2 for diabetic kidney disease) will be proposed to undertake AVF creation. Maturation rate and time of AVF will be followed up in 3 months; primary and secondary patency rate of AVF, AVF construction on cardiac structure, function, encephalopathy, cerebral vascular lesions and cognitive function will be followed up in the next 2 years. This multicenter will provide evidence to develop guideline of timing for AVF creation

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Lower eGFR for AVF constructionProcedure or surgery

    Also called late AVF construction

    Lower eGFR patients (eGFR<10ml/min 1.73m2 for patients without diabetic kidney disease, and eGFR<15ml/min 1.73m2 for diabetic kidney disease) are proposed to undergo AVF construction

  • Higher eGFR for AVF constructionProcedure or surgery

    Also called early AVF construction

    Higher eGFR patients (eGFR 10-15ml/min 1.73m2 for patients without diabetic kidney disease, and eGFR 15-20ml/min 1.73m2 for diabetic kidney disease) are proposed to undergo AVF construction

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maturation rate of AVF

    Assessed by duplex ultrasound. A mature fistula has a flow of over 500 mL/min,is less than 0.6 cm below the surface of the skin, and has a minimal diameter of 0.6 cm

    Measured: 3 months

  2. Primary and secondary patency rate of AVF

    Assessed by duplex ultrasound

    Measured: 2 years

Secondary outcomes (4)
  1. Maturation time of AVF

    Assessed by duplex ultrasound

    Measured: 3 months

  2. Complications of AVF

    Assessed by duplex ultrasound

    Measured: 2 years

  3. AVF creation on ventricular volumes and left ventricular remodeling

    Assessed by doppler echocardiography

    Measured: 2 years

  4. AVF creation on AVF creation on brain MRI and cognitive functions

    Cognitive functions are assessed by psychic and autonomy scores

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A study testing Lower eGFR for AVF construction and Higher eGFR for AVF construction in people with Renal Failure, Chronic, run by Shanghai Changzheng Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 8 Oct 2014. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Xiang Gao (+862181885397, gaoxiang43100636@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maturation rate of AVF (time frame: 3 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Oct 2014.
