About this study

The purpose of this study is to evaluate the predictive value of serum adiponectin levels in aneurysmal subarachnoid hemorrhage patients.

Read the detailed description

Adiponectin (APN) is an abundant protein hormone derived from adipose tissue. It has been suggested to exert anti-inflammatory, antiatherogenic, and vascular protective. Subarachnoid hemorrhage (SAH) comprises about 5% of all strokes with high mortality and permanent disability rates. Although many patients survive from the initial hemorrhage or rebleeding, they suffered from long-term delayed neurological deficits (DNDs), including stroke, delayed cerebral ischemia, cognitive and neuropsychological abnormalities that seriously impact overall function and quality of life. Ruptured cerebral aneurysms are the most common cause of SAH. There is growing evidence supporting APN act as a predictive factor for SAH. The observational study will focus on the predictive value of serum adiponectin levels in aneurysmal subarachnoid hemorrhage (aSAH).

    Measured: On discharge or 14 days (whichever occurs first) and 30 days post SAH

  3. Modified Rankin scale (mRS)

    By phone call following-up

    Measured: 30 days and 90days post SAH

Questions about this trial

What is this clinical trial studying?

An observational study of Subarachnoid Hemorrhage, Aneurysmal, run by Tang-Du 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 5 inclusion and 5 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 31 Mar 2017. 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?

What does the primary outcome measure?

Incidence of cerebral vasospasm and delayed cerebral ischemia (time frame: 30 days post SAH). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02814162, which also lists 7 linked publications.

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 31 Mar 2017.
