Steroids for acute spinal cord injury

Area of Science:

• Neurology
• Traumatology
• Pharmacology

Background:

• Acute spinal cord injury (SCI) is a severe condition predominantly affecting young males.
• Early steroid treatment aims to minimize permanent paralysis post-injury.

Purpose of the Study:

• To systematically review randomized controlled trials (RCTs) investigating steroid efficacy in acute human SCI.
• To synthesize evidence on the optimal timing and duration of steroid administration for SCI patients.

Main Methods:

• Comprehensive literature search of multiple databases (Cochrane, MEDLINE, EMBASE, Web of Science, PubMed) up to August 2011.
• Inclusion of all RCTs of steroid treatment for acute SCI, regardless of language.
• Data extraction by one author, with additional data obtained from study authors for meta-analysis.

Main Results:

• Eight RCTs were included, with seven using methylprednisolone.
• Methylprednisolone sodium succinate administered within 8 hours of injury improved neurologic outcomes up to one year.
• A 48-hour treatment regimen showed additional benefits in motor function and functional status, particularly when initiated 3-8 hours post-injury.
• No significant increase in complications or mortality was observed with 23 or 48-hour therapy.

Conclusions:

• High-dose methylprednisolone is the only pharmacologic therapy proven effective in phase III RCTs for acute SCI when given within 8 hours.
• Extending methylprednisolone therapy to 48 hours may enhance recovery, especially with delayed treatment initiation.
• Further RCTs are urgently needed to explore pharmacologic interventions for acute SCI.
