What is the role of steroids in the management of ischemic stroke?

From the Guidelines

Steroids are not recommended for the routine management of ischemic stroke. The most recent and highest quality evidence from the American Heart Association/American Stroke Association guidelines [ 1 ] clearly states that corticosteroids are not recommended for treatment of cerebral edema and increased ICP complicating ischemic stroke due to lack of evidence of efficacy and potential to increase infectious complications. This recommendation is classified as Class III, Level of Evidence A, indicating that the use of corticosteroids is not recommended and may be harmful.

The primary mechanism of ischemic stroke involves neuronal damage from oxygen deprivation rather than inflammation, which explains why anti-inflammatory steroids have limited benefit in this condition. Instead, the focus of treatment for acute ischemic stroke is on reperfusion strategies, including intravenous thrombolysis with alteplase (tPA) within 4.5 hours of symptom onset and mechanical thrombectomy for eligible patients with large vessel occlusions.

Some specific exceptions where steroids may have a role include managing vasogenic edema associated with large cerebellar infarcts or when stroke is caused by inflammatory vasculitis, but these are not standard care and should be approached with caution. The older guidelines from 2003 [ 1 ] also support the notion that corticosteroids are not recommended for the management of cerebral edema and increased intracranial pressure following ischemic stroke, with a grade A recommendation against their use.

Key points to consider in the management of ischemic stroke include:

• Early recognition and treatment to improve outcomes
• Use of reperfusion strategies as appropriate
• Monitoring for and management of complications such as cerebral edema and seizures
• Individualized care based on patient-specific factors and conditions.

From the Research

Role of Steroids in Ischemic Stroke

• The use of steroids in the management of ischemic stroke is a topic of ongoing debate, with some studies suggesting a potential benefit and others finding no significant effect 2, 3.
• A 2011 Cochrane review found that corticosteroids did not improve functional outcomes or reduce mortality in patients with acute ischemic stroke 2.
• A 1986 study found that high-dose steroid treatment was ineffective in improving outcomes in patients with ischemic stroke, and may even expose patients to unnecessary risks 3.
• The current management of ischemic stroke focuses on general measures to ensure patient hemodynamic stability, reperfusion therapies, and prevention of cerebral and systemic complications, but does not typically include the use of steroids 4.
• Secondary prevention of ischemic stroke includes optimization of chronic disease management, nonpharmacologic lifestyle interventions, and pharmacologic interventions, but steroids are not typically recommended 5.
• It's worth noting that the use of steroids may be more beneficial in the management of hemorrhagic stroke, as suggested by a 2011 study that found improved outcomes in patients treated with intravenous dexamethasone 6.

Key Findings

• No significant benefit of steroids in improving functional outcomes or reducing mortality in patients with acute ischemic stroke 2, 3.
• Current management of ischemic stroke does not typically include the use of steroids 4, 5.
• Steroids may be more beneficial in the management of hemorrhagic stroke, but more research is needed to confirm this 6.

Implications for Practice

• Clinicians should be aware of the current evidence on the use of steroids in ischemic stroke and consider alternative treatments that have been shown to be effective 4, 5.
• Further research is needed to fully understand the potential benefits and risks of steroid use in ischemic stroke 2, 3.
