High Serum Levels of Caspase-3 and Early Mortality in Patients with Severe Spontaneous Intracerebral Hemorrhage.

Background: Apoptotic cell death leads to secondary brain injury after spontaneous intracerebral hemorrhage (SIH). There is an association between serum caspase-3 levels and late mortality (at 6 months) in patients with SIH in basal ganglia. The new objective of this study was to determine whether there exists an association between serum caspase-3 levels and early mortality (at 30 days) in patients with SIH at different sites and not only in basal ganglia.

Methods: Patients with severe supratentorial SIH (defined as Glasgow Coma Scale < 9) admitted in 6 Spanish hospitals were included in this observational and prospective study. Patients with SIH due to aneurysm, arteriovenous malformation, and anticoagulant or fibrinolytic treatment were excluded. Serum caspase-3 levels at days 1, 4, and 8 of SIH were determined. Thirty-day mortality was the end-point study.

Results: Non-surviving (n = 53) showed higher serum caspase-3 levels at days 1 (p < 0.001), 4 (p < 0.001), and 8 (p < 0.001) than survivor patients (n = 64). Multiple logistic regression analysis showed an association of serum caspase-3 levels > 0.167 ng/mL with 30-day mortality (Odds Ratio = 47.007; 95% CI = 4.838-456.727; p = 0.001).

Conclusions: The new findings of our study are that serum caspase-3 levels are associated with early mortality in patients with severe supratentorial SIH at different sites and that those levels during the first week of SIH are higher in non-survivors than in survivors.
