About this study

Stroke is the second largest cause of death globally after ischemic heart disease.Of the total number of prevalent strokes, 84.4% are ischemic. Reperfusion therapy is the most important treatment for acute ischemic stroke (AIS) ,including intravenous thrombolysis and/or endovascular treatment.However,the most serious and common complication with reperfusion therapy is hemorrhage transformation(HT),which significantly increases disability and mortality. The fundamental mechanism leading to post-stroke HT is the disruption of the blood brain barrier(BBB) and increase of permeability.Endocan plays a critical role in vascular inflammatory responses by enhances the production of pro-inflammatory cytokines by endothelial cells,the expression of adhesion molecules such as inter-cellular adhesion molecule-1(ICAM-1) and vascular cell adhesion molecule-1(VCAM-1),and the adhesion of leukocytes to endothelial cells. Endocan significantly decreases levels of zonula occludens(ZO-1) and occludin which are tight junction proteins that play major roles in the maintenance of vascular barriers. Endocan could induce vascular endothelial growth factor-A(VEGF-A) and facilitate the binding of VEGF-A to its receptor(VEGFR-2) to enhanced endothelial permeability.Therefore,endocan is a reliable biomarker of endothelial dysfunction, which may be associated with disruption of the BBB. In this context, the investigators hypothesized that elevated pretreatment serum endocan levels might be independently associated with HT after reperfusion therapy in the acute phase of ischemic stroke. Serum endocan,ICAM-1,VCAM-1 and matrix metalloproteinase-9(MMP-9) levels will be determined by enzyme-linked immunosorbent assay(ELISA) in blood samples obtained at baseline (pretreatment) and at 12,24 hours after reperfusion therapy in patients with acute stroke and in healthy subjects.In the present study,the investigators attempt to investigate whether high levels of endocan are associated with HT in patients who received reperfusion therapy.In addition,the investigators explore the association between serum endocan and early neurological deterioration and unfavourable short-term prognosis.

What participants receive

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

  • enzyme-linked immunosorbent assay(ELISA)Diagnostic test

    Peripheral blood samples will be drawn from each patient at study entry (before reperfusion therapy) and at 12,24 hours after reperfusion therapy.Serum will be immediately separated by centrifugation at 3000 rpm for 15 minutes and stored at -80°C. Endocan,ICAM-1,VCAM-1,MMP-9 levels will be determined in duplicate by commercially available enzyme-linked immunosorbent assay (ELISA).

What is being measured

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

  1. Incidence of Hemorrhagic Transformation after reperfusion therapy

    Patients will undergo the cranial CT at 24 to 48 hours after reperfusion therapy to identify intracranial hemorrhage

    Measured: At 24 to 48 hours after reperfusion therapy

Secondary outcomes (2)
  1. Incidence of early neurological deterioration

    Either death or an increase in the NIHSS score by ≥4 points from baseline to 24 hours after reperfusion therapy

    Measured: At 24 hours from reperfusion therapy

  2. Incidence of unfavourable short-term prognosis

    Death and major disability (modified Rankin Scale score ≥3) at 90 days after stroke onset

    Measured: At 90 days after stroke onset

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Ischemic Stroke, run by Xijing Hospital 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 9 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 1 Jun 2022. 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 JIA-NING WU (15353390103, wjn19961230@yeah.net), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Hemorrhagic Transformation after reperfusion therapy (time frame: At 24 to 48 hours after reperfusion therapy). 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 1 Jun 2022.
