About this study
The purpose of this study is to validate results from a related trial (NCT01791257) and to compare the profile of microRNA in blood from patients suffering subarachnoid hemorrhage with and without systemic complications.
Read the detailed description
In this study of patients suffering an aneurysmal subarachnoid hemorrhage (SAH) we would like to validate former results from CSF studies through microRNA profiling investigate the pathophysiological mechanisms that lead to systemic complications such as cardiac dysfunction, acute lung injury (ALI) and systemic inflammatory response syndrome(SIRS).
We will accomplish this through analyzing the profile of microRNA expression in blood and cerebrospinal fluid from SAH patients.
Validation:
As in our earlier study we wish to compare the expression of 20 specific microRNA between 12 patients developing DCI (group 1) and 12 patients without DCI (group 2) in cerebrospinal fluid drawn on day 5 after ictus. In addition, some of the patients will have established invasive neuromonitoring including microdialysis in which we will study changes of certain microRNAs.
DCI as defined by Vergouwen et al in Stroke 2010;41(10):2391-2395:
"The occurrence of focal neurological impairment (such as hemiparesis, aphasia, apraxia, hemianopia, or neglect), or a decrease of at least 2 points on the Glasgow Coma Scale (either on the total score or on one of its individual components [eye, motor on either side, verbal]). This should last for at least 1 hour, is not apparent immediately after aneurysm occlusion, and cannot be attributed to other causes by means of clinical assessment, CT or MRI scanning of the brain, and appropriate laboratory studies."
Systemic complications:
Furthermore, we wish to compare the expression of 754 specific microRNA in blood drawn on day 3 after ictus between patients with ALI (as described Kahn et al, Crit Care Med. 2006; 34: 196-202) and patients without ALI. Of at least 36 patients expected to be included 12 should statistically develop ALI according to the referred definition.
Additionally, we wish to compare the expression of 754 specific microRNA between 12 patients developing DCI (group 1) and 12 patients without DCI (group 2) in blood drawn on day 3 after ictus.
Moreover, we wish to compare the expression of 754 specific microRNA in blood between 36 patients (group 1-3) to that of healthy controls. The specific microRNAs of interest in which the expression in blood between patients with systemic complication are analyzed daily to investigate the dynamic changes in expression and compared to the clinical course.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| SAH with DCI | After 21 days from ictus the patients with subarachnoid hemorrhage are stratified to group 1 or 2 depending on their development of delayed cerebral ischemia. | |
| SAH without DCI | After 21 days from ictus the patients with subarachnoid hemorrhage are stratified to group 1 or 2 depending on their development of delayed cerebral ischemia. | |
| SAH good grade | SAH without external ventricular drainage | |
| Healthy controls | Blood sample in healthy donors registered in the National Donor Registry. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Delayed Cerebral Ischemia
Delayed Cerebral Ischemia as defined by Vergouwen et al[1]. In our earlier study we found the clinical condition DCI somehow subjective which is why we added the following two primary outcome measures.
Comparing microRNA profiles between groups with or without.
Measured: 21 days
Delayed Cerebral Ischemia and Cerebral infarction
as defined by Vergouwen et al [1].
Comparing microRNA profiles between groups with or without.
Measured: 21 days

Comparing microRNA profiles between groups with or without.
Measured: 21 days
Secondary outcomes (4)
Acute Lung Injury
as defined by Kahn et al[2].
Comparing microRNA profiles between groups with or without
Measured: 21 days
Cardiac Dysfunction
Evaluated by transthoracic echocardiography
Comparing microRNA profiles between groups with or without
Measured: 21 days
Systemic Inflammatory Response Syndrome
Evaluated through daily vital signs and biochemistry
Comparing microRNA profiles between groups with or without
Measured: 21 days
Early Brain Injury
Early Brain injury = GCS 3-12 and/or paresis (degree 4) of at least one extremity or aphasia No Early Brain injury = GCS 13-15 and no or only small and mild focal deficit
Comparing microRNA profiles between groups with or without
Measured: Clinical evaluation 24-72 hours after ictus. (Wake-up call if sedated)

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Delayed Cerebral Ischemia (time frame: 21 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?
On the ClinicalTrials.gov record for NCT02320539, which also lists 1 linked publication.
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 27 May 2015; AzTrials last refreshed its copy on 6 Nov 2026.
