About this study

Official title: the Application of Diffusion Tensor Imaging(DTI) in the Evaluation of Peripheral Neuropathy in Anti-neutrophil Cytoplasmic Antibodies Associated Vasculitis(AAV)

  1. Include qualified 50 ANCA-associated vasculitis(AAV) patients; and the first 27 patients will be divided into 3 groups with different diffused tension image (DTI) parameters and to choose the best strategy;
  2. On baseline, 6 months after treatment and 24 months after treatment, the AAV patients will accomplish the Birming-ham vasculitis activity score(BVAS) besides DTI;
  3. The new serum biomarkers of AAV associated peripheral neuropathy will be measured by ELISA; (4) Another cohort with 50 patients with AAV associated peripheral neuropathy who were evaluated by traditional methods (electromyogram) and compared to the patients cohort that evaluated using DTI by cost-benefit analysis

What participants receive

What is being measured

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

  1. To assess the optimal b-value (a key parameter) for DTI in AAV associated peripheral neuropathy

    b-value is a key technique parameter for DTI, which will decide the quality of DTI image

    Measured: 2 years

Secondary outcomes (2)
  1. the association between normative diffusion value of DTI (FA and ADC value) and disease activity activity score of AAV (BVAS).

    Birmingham Vasculitis Activity Score (BVAS) is a index of vasculitis disease activity, with the score range 0-63. Fractional anisotropy(FA) and apparent diffusion coefficient(ADC) are two parameters that can be read through DTI image .

    Measured: 2 years

  2. the association between normative diffusion value of DTI (FA and ADC value) and serum biomarkers of AAV associated neuropathy

    sCD163, Nfl(neurofilament light polypeptide)and OPN(osteopontin)are new biomarkers of peripheral neuropathy

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of ANCA Associated Vasculitis, run by Second Affiliated Hospital, Zhejiang University, School of Medicine at 1 site in China.

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 4 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 11 Jun 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

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 wenjia sun (86 15869029727, sunwinjoy@zju.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To assess the optimal b-value (a key parameter) for DTI in AAV associated peripheral neuropathy (time frame: 2 years). 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 11 Jun 2021.
