Significant elevation of serum caspase-3 levels in patients with intracerebral hemorrhage.

Background: Caspase-3 is a potential marker of apoptosis. We investigated whether serum caspase-3 concentrations were increased and its association with severity and prognosis after intracerebral hemorrhage (ICH).
Methods: This prospective clinical study recruited 112 ICH patients and 112 healthy individuals. Serum was assayed for caspase-3 using enzyme-linked immunosorbent assay. Stroke severity was quantified by National Institute of Health Stroke Scale (NIHSS) and hematoma volume. Six-month outcome was measured by modified Rankin Scale. Analyses were performed using univariate and multivariate analyses.
Results: Patients had significantly higher serum caspase-3 concentrations than controls. Capase-3 concentrations correlated with NIHSS score and hematoma volume. Serum caspase-3 emerged as an independent predictor for 6-month mortality and bad prognosis (modified Rankin scale score>2). Based on receiver operating characteristic curve, caspase-3 concentrations showed similar prognostic value when compared with NIHSS score and hematoma volume.
Conclusion: Serum caspase-3 concentrations are increased in ICH patients as well as correlate with clinical severity and prognosis.
