Predictive Role of sTREM in Endovascular Thrombectomy Outcomes

Recruiting
Conditions
Acute Ischemic Stroke
Registration Number
NCT06545591
Lead Sponsor
The Affiliated Hospital of Xuzhou Medical University
Brief Summary

Soluble triggering receptor expressed on myeloid cells (sTREM), which reflects microglia activation, has been reported closely associated with neuronal injury and neuroinflammation. This study is to investigatethe prognostic roles of sTREM (sTREM1 and sTREM2) in patients with ischemic stroke who underwent endovascular thrombectomy (EVT).

Detailed Description

For acute ischemic stroke, the current treatment strategy involves timely recanalization by intravenous thrombolysis and endovascular thrombectomy (EVT). Patients receiving EVT are more likely to achieve successful revascularization and long--term functional independence compared with those receiving standard medical treatment.1 In patients receiving EVT, significant predictors of a favorable functional outcome include minor initial stroke severity, successful recanalization, and shorter onset--to--treatment time. However, unfavorable outcomes can occur even after early successful recanalization in some cases.Triggering receptors expressed on myeloid cells (TREM-1 and TREM-2) are a familyof receptors involved in the immune system expressed on a variety of innate cells of the myeloid lineage, including microglia. sTREM, which reflects microglia activation, has been reported closely associated with neuronal injury and neuroinflammation. We enrolled adult patients with stroke who received EVT, with blood sampling immediately before (T1) and after EVT (T2), and at 24 hours after EVT (T3). Non--stroke controls and patients with non--EVT stroke were also enrolled. The plasma concentration of sTREM1 and sTREM2 were analyzed by ELISA. The medical information, image findings and levels of plasma sTREM1 and sTREM2 were analyzed to clarify the association with poor functional outcome (modified Rankin Scale 4-6) at 3 months after stroke.

Primary Outcome Measures
NameTimeMethod
Dynamic changes in plasma levels of sTREM-1 and sTREM-2 following Endovascular TherapyFrom baseline to immediately, 24 hours, 3 days, and 7 days after Endovascular Therapy

Plasma levels of sTREM-1 and sTREM-2 will be quantified using the ELISA method.

Secondary Outcome Measures
NameTimeMethod
favourable functional outcome, defined as modified Rankin Scale (mRS) 0-290 days

mRS ranges from 0-6, high score means poor outcome

excellent functional outcome, defined as modified Rankin Scale (mRS) 0-130 days

mRS ranges from 0-6, high score means poor outcome

Hemorrhagic transformation72 hours

Hemorrhagic transformation was diagnosed by Computed tomographic scans usually performed 24 to 72 hours after the procedure.Symptomatic intracranial hemorrhage was defined as neurologic deterioration (an increase of 4 or more points in the score on the NIHSS) and evidence of intracranial hemorrhage on imaging studies.

early neurological improvement, defined as 4 or more decrease in National Institute of Health stroke scale (NIHSS)24 hours

NIHSS ranges from 0-22, with high score meaning severe neurological deficit.
