Abstract

BACKGROUND AND PURPOSE:

Early infection after stroke is frequent but the clinical value of antibiotic prophylaxis in acute stroke has never been explored.

OBJECTIVE AND METHODS:

The Early Systemic Prophylaxis of Infection After Stroke (ESPIAS) is a randomized, double-blind, placebo-controlled study of antibiotic prophylaxis in patients older than 18 years with nonseptic ischemic or hemorrhagic stroke enrolled within 24 hours from clinical onset. Interventions included intravenous levofloxacin (500 mg/100 mL/d, for 3 days) or placebo (0.9% physiological serum) in addition to optimal care. A sample size of 240 patients was calculated to identify a 15% absolute risk reduction of the primary outcome measure, which was the incidence of infection at day 7 after stroke. Secondary outcome measures were neurological outcome and mortality at day 90.

RESULTS:

Based on a preplanned futility analysis, the study was interrupted prematurely when 136 patients had been included. Levofloxacin and placebo patients had a cumulative rate of infection of 6% and 6% (P=0.96) at day 1; 10% and 12% (P=0.83) at day 2; 12% and 15% (P=0.66) at day 3; 16% and 19% (P=0.82) at day 7; and 30% and 33% (P=0.70), at day 90. Using logistic regression, favorable outcome at day 90 was inversely associated with baseline National Institutes of Health Stroke Scale (OR, 0.72; 95% CI, 0.59 to 0.89; P=0.002) and allocation to levofloxacin (OR, 0.19; 95% CI, 0.04 to 0.87; P=0.03).

CONCLUSIONS:

Prophylactic administration of levofloxacin (500 mg/100 mL/day for 3 days) is not better than optimal care for the prevention of infections in patients with acute stroke.
