BackgroundThe effect of prophylactic antiepileptic drugs (AEDs) on mortality and functional outcome in patients with intracerebral hemorrhage (ICH) is uncertain.MethodsWe used data from the Virtual International Stroke Trials Archive (VISTA) to evaluate the effect of prophylactic AEDs on ICH outcome. Univariate and multivariate logistic and Cox regression models were designed to determine the impact of prophylactic AEDs on mortality and disability, defined as a modified Rankin Scale (mRS) greater than 3 at 90 days following ICH.ResultsOf the 802 patients with ICH, 81 (10%) received prophylactic AEDs. Patients who received AED prophylaxis had higher ICH volume (median 23.2 cm(3) [IQR 10.5-38.0] versus 14.3 cm(3) [IQR 7.1-27.0], P= .001) and ICH score (median 1 cm(3) [IQR 0-2] versus 1 cm(3) [IQR 0-1], P = .03). In univariate analyses, AED prophylaxis was associated with higher probability of mRS greater than 3 at 90 days (62% versus 49%, P = .03) and a trend towards increased mortality (27% versus 18%, P = .06). Although seizure did not influence ICH outcome, any AED prophylaxis and phenytoin use in particular were both associated with mRS greater than 3 at 90 days (OR 1.66 [1.04-2.66], P = .03 for any AED; OR 1.97 [1.06-3.67], P = .03 for phenytoin prophylaxis) in univariate analyses. After adjustment for components of the ICH score, none of these associations remained significant.ConclusionPatients with higher ICH scores and larger hemorrhages are more likely to receive prophylactic AEDs. We found no independent effect of prophylactic AED treatment on outcome after ICH.Copyright © 2016 National Stroke Association. Published by Elsevier Inc. All rights reserved.
