Prognostic significance of plasma copeptin detection compared with multiple biomarkers in intracerebral hemorrhage.

Background: Higher plasma copeptin concentrations have been associated with poor clinical outcomes after intracerebral hemorrhage. This study was designed to compare plasma concentrations of copeptin and other biomarkers like myelin basic protein, glial fibrillary astrocyte protein, S100B, neuron-specific enolase, phosphorylated axonal neurofilament subunit H, tau and ubiquitin carboxyl-terminal hydrolase L1 for analysis of their prognostic prediction.
Methods: We measured plasma concentrations of these biomarkers in 118 healthy controls and in 118 acute patients with a comparison analysis for their prediction of 6-month mortality and unfavorable outcome (modified Rankin Scale score>2).
Results: Plasma concentrations of these biomarkers were statistically significantly higher in all patients than in healthy controls, in non-survivors than in survivors and in patients with unfavorable outcome than with favorable outcome. Areas under receiver operating characteristic curves of plasma concentrations of these biomarkers were similar to those of the National Institute of Health Stroke Scale score for prognostic prediction. Plasma copeptin concentration statistically significantly improved the prognostic predictive value of the National Institute of Health Stroke Scale score, but other biomarkers did not.
Conclusions: Copeptin may help in the prediction of long-term clinical outcomes after intracerebral hemorrhage.
