Corticosteroids do not show a benefit in reducing death or improving functional outcomes for acute ischemic stroke patients. More evidence is needed to evaluate their effectiveness and safety in this condition.

Area of Science:

  • Neurology
  • Clinical Medicine
  • Pharmacology

Background:

  • Ischemic stroke often causes brain swelling due to cytotoxic edema, linked to cell membrane dysfunction.
  • Corticosteroids are being investigated for their potential to reduce swelling and improve stroke outcomes.

Purpose of the Study:

  • To systematically review the efficacy of corticosteroid treatment in acute presumed ischemic stroke.

Main Methods:

  • Searched the Cochrane Stroke Group trials register and contacted investigators.
  • Included randomized trials comparing corticosteroids with placebo in acute ischemic stroke, with treatment initiated within 48 hours.
  • Two independent reviewers assessed trial quality and extracted data.

Main Results:

  • Seven trials with 453 participants were analyzed; most lacked quality details.
  • No significant difference in one-year mortality (OR 1.08, 95% CI 0.68-1.72) was observed.
  • Functional outcomes and neurological impairment data were inconclusive due to inconsistent reporting and pooling difficulties; adverse effects included minor gastrointestinal bleeds and infections.

Conclusions:

  • Insufficient evidence exists to support or refute the use of corticosteroids for acute presumed ischemic stroke.
  • Current findings indicate no clear benefit, and further research is required to establish efficacy and safety.
