Stroke and Traumatic Acute Brain Injury Line Indicator System for Emergent Recognition (STABILISER-I)

2015-08-04 16:08:23 | BioPortfolio


In the search for a novel marker of stroke that could be rapidly assessed in blood, the investigators developed a point-of-care (POC) lateral flow device (LFD) that rapidly (< 15 min) detects levels of a biomarker that is released into blood following neuronal injury associated with stroke and traumatic brain injury. The protein's expression in human brain should serve as a useful biomarker of neuronal injury in stroke and traumatic brain injury.


The use of a lateral flow device (LFD) to indicate the presence of a blood biomarker is feasible and may provide an important diagnostic tool for stroke and traumatic brain injury (TBI).

Primary Objectives:

1. Determine the first-in-humans feasibility using the investigators' biomarker lateral flow device on whole blood samples to diagnose patients with acute stroke (both ischemic and hemorrhagic) and traumatic brain injury being evaluated in the Emergency Department and Inpatient Services at University of Kentucky. Provide initial pilot data for estimating sensitivity and specificity of the assay.

2. Establish a visual ordinal grading scale that is easy to use clinically to judge the severity of injury, from the Lateral Flow Device result. Verify that the visual scale has inter-rater reliability, and evaluate it against a digital detection assay.

3. Examine the correlation between clinical and radiographic parameters of injury severity and blood levels of the biomarker. The investigators will correlate the results of the test with NIH Stroke Scale and with MRI infarct volume for ischemic stroke, with hemorrhage volume on CT for hemorrhagic stroke, and with Glasgow Coma Scale for Traumatic Brain Injury (TBI).

Medical and Biotech [MESH] Definitions

The application of repeated, brief periods of vascular occlusion at the onset of REPERFUSION to reduce REPERFUSION INJURY that follows a prolonged ischemic event. The techniques are similar to ISCHEMIC PRECONDITIONING but the time of application is after the ischemic event instead of before.

Damage to the MYOCARDIUM resulting from MYOCARDIAL REPERFUSION (restoration of blood flow to ischemic areas of the HEART.) Reperfusion takes place when there is spontaneous thrombolysis, THROMBOLYTIC THERAPY, collateral flow from other coronary vascular beds, or reversal of vasospasm.

A drug combination of aspirin and dipyridamole that functions as a PLATELET AGGREGATION INHIBITOR, used to prevent THROMBOSIS and STROKE in TRANSIENT ISCHEMIC ATTACK patients.

Ischemic injury to the OPTIC NERVE which usually affects the OPTIC DISK (optic neuropathy, anterior ischemic) and less frequently the retrobulbar portion of the nerve (optic neuropathy, posterior ischemic). The injury results from occlusion of arterial blood supply which may result from TEMPORAL ARTERITIS; ATHEROSCLEROSIS; COLLAGEN DISEASES; EMBOLISM; DIABETES MELLITUS; and other conditions. The disease primarily occurs in the sixth decade or later and presents with the sudden onset of painless and usually severe monocular visual loss. Anterior ischemic optic neuropathy also features optic disk edema with microhemorrhages. The optic disk appears normal in posterior ischemic optic neuropathy.
