About this study

Remote limb ischemic preconditioning is neuro-protective and anti-inflammatory for ischemia- reperfusion injury. As the extent of its effect is unknown, the investigators will use clinical outcome, serum biochemical markers and diffusion-weighted magnetic resonance imaging (DW-MRI)to determine the extent of its neuro-protective and anti-inflammatory effect.

Read the detailed description

BACKGROUND: Brain ischemia and injury contributed to perioperative morbidity and mortality in Carotid Artery Stenting. Remote ischemic preconditioning (RIPC) is a phenomenon whereby brief periods of ischemia followed by reperfusion in one organ provide systemic protection from prolonged ischemia. To investigate whether remote preconditioning protects the brain injury in patients undergoing elective Carotid Artery Stenting, a randomized trial will be performed in current study.

DESIGNING 60 patients will be randomized to Carotid Artery Stenting with RIPC group or conventional Carotid Artery Stenting group (control). RIPC consisted of five 5-min cycles of right upper arm ischemia/reperfusion, which was induced by an automated cuff-inflator placed on the right upper arm which was inflated to 200 mmHg for 5mins followed by deflating the cuff for 5mins. Cerebral injury was assessed by S-100b, NSE, hs-CRP and MMSE test in different time points.

What is being measured

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

  1. cognitive disorder assessment

    1.The Mini-Mental State Examination( MMSE) test: The difference in MMSE score among patients treated with preconditioning and those not treated.

    Measured: 2 days

  2. serum biomarkers

    Serum biomarkers of brain injury and flammatory: The difference in NSE, S-100b and hs-CRP level among patients treated with preconditioning and those not treated.

    Measured: 2 days

  3. new brain lesions

    The new lesions at DWI-MRI within postoperation 48 hours: The difference in new lesions in the DWI-MRI 48 hours postoperatively among patients treated with preconditioning and those not treated.

    Measured: 2DAYS

Secondary outcomes (1)
  1. composite endpoint of any stroke,MI,or death

    The composite endpoint of any stroke ,MI, or death at 30-day and 90-day after the procedure.

    Measured: 3months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing remote limb ischemic preconditioning and Carotid Artery Stenting in people with Stroke and TIA, run by Capital Medical University 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 0 inclusion and 10 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 6 Aug 2010. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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 Xunming Ji Ji, M.D.,Ph.D. (8683198127, jixm70@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

cognitive disorder assessment (time frame: 2 days). The study lists 3 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 6 Aug 2010.
