Visinin-like protein-1 level is associated with short-term functional outcome of acute ischemic stroke: A prospective...

Stroke is a serious disease that can lead to disability and death in adults, and the prediction of functional outcome is important in the management of acute ischemic stroke (AIS). Blood biomarker is a promising technique, for the measurement is fast, cheap and convenient. Visinin-like protein-1 (VILIP-1) is a classic stroke biomarker, thus we tried to investigate the predictive value of VILIP-1 for early functional outcomes of AIS.A total of 70 AIS patients were enrolled in our study. Venous blood samples of all patients were taken at day 3 after admission to the stroke unit, and levels of serum VILIP-1 were analyzed by the use of the enzyme-linked immunosorbent assay. All subjects underwent diffusion weighted imaging (DWI) of the brain MRI scanning at 72 hours after stroke onset, and infarct volumes were calculated. Initial neurological status was evaluated by the National Institutes of Health Stroke Scale (NIHSS) on admission. The short-term functional outcome was graded by the modified Rankin Scale (mRS) at discharge from the hospital. Baseline data between the favorable outcome group and poor outcome group were compared, and univariate and multivariable logistic regression analysis were used to identify risk factors of early functional outcome of AIS.The multivariate logistic regression analysis showed age, initial NIHSS scores and levels of VILIP had a strong association with poor clinical outcomes.Levels of serum VILIP-1 are associated with short-term functional outcomes in patients with AIS.
