Predictive value of serum visinin-like protein-1 for early neurologic deterioration and three-month clinical outcome in acute primary basal ganglia hemorrhage: A prospective and observational study

Background: Visinin-like protein 1 (VILIP-1) appears as a biomarker of neuronal injury. We investigated the correlation of serum VILIP-1 concentrations with severity, early neurologic deterioration (END) and functional outcome of intracerebral hemorrhage (ICH). Methods: In this prospective and observational study, serum VILIP-1 concentrations were quantified in 106 patients with basal ganglia hemorrhage. Univariate and multivariable logistic regression analyses were used to analyze the relationship between serum VILIP-1 concentrations and END plus worse prognosis (modified Rankin Scale score of 3 or greater) at post-injury 3 months.Results: Serum VILIP-1 concentrations of patients were closely correlated with hematoma volume and National Institutes of Health Stroke Scale score. Serum VILIP-1 concentrations were substantially elevated in patients with END or worse 3-month prognosis, as compared to other remainders. Also, serum VILIP-1 concentrations were independently associated with END and worse 3-month prognosis. Under ROC curve analysis, serum VILIP-1 concentrations exhibited marked accuracy for distinguishing patients with the development of END or worse 3-month prognosis. Its predictive ability was in the range of hematoma volume and National Institutes of Health Stroke Scale score.Conclusions: Serum VILIP-1 may be a good biomarker for assessing hemorrhagic severity and clinical outcomes after ICH.
