In an elderly male with acute compressive myelopathy and severe cord edema awaiting surgery, what high‑dose steroid regimen is recommended and what are the contraindications?

High-Dose Dexamethasone for Compressive Myelopathy in Elderly Males

For an elderly male with acute compressive myelopathy and severe cord edema awaiting surgery, initiate dexamethasone immediately with a 10 mg IV bolus followed by 16 mg daily (divided as 4 mg every 6 hours), and taper rapidly after definitive treatment begins. 1, 2, 3

Immediate Steroid Regimen

Standard Dosing Protocol

• Administer dexamethasone 10 mg IV bolus immediately upon clinical suspicion, even before MRI confirmation 1, 2
• Follow with maintenance dose of 16 mg daily, divided as 4 mg IV or PO every 6 hours 1, 2, 3
• Begin tapering over 10-14 days once definitive treatment (surgery or radiotherapy) is initiated 4, 1

High-Dose Regimen (Use Selectively)

• High-dose regimen consists of 96 mg IV daily, sometimes preceded by a 10-100 mg bolus 4, 1, 2
• Reserve high-dose dexamethasone (96 mg/day) only for patients with rapidly progressive neurological deficits or unstable spine 1, 2
• High-dose therapy improves ambulation rates (81% vs 63% without steroids at 3 months) but carries 11-29% risk of serious complications including GI perforation, bleeding, and severe psychosis 1, 2, 3

Evidence-Based Rationale

The moderate-dose regimen (16 mg/day) provides comparable neurological outcomes with significantly fewer adverse effects (7.9% vs 28.6%) compared to high-dose therapy 2. While high-dose regimens may provide slightly better motor improvement (25% vs 8%), this difference was not statistically significant 2. Given the elderly patient population with likely multiple comorbidities, the moderate-dose regimen is strongly preferred unless there is rapid neurological deterioration 1, 2, 3.

Critical Contraindications and Cautions

Absolute Contraindications

• Do NOT use steroids for traumatic spinal cord injury—they provide no neurological benefit and increase infectious complications 2, 5
• Avoid steroids in suspected CNS lymphoma prior to biopsy, as they may obscure diagnosis 4

Relative Contraindications in Elderly Patients

• Active or recent GI ulceration/bleeding requires concurrent proton pump inhibitor or H2 blocker 4, 3
• Uncontrolled diabetes mellitus (monitor glucose closely; steroids cause refractory hyperglycemia) 4
• Active systemic infection (steroids increase risk of infectious complications) 4, 5
• Recent myocardial infarction or heart failure (steroids cause fluid retention) 4

High-Risk Complications to Monitor

• GI perforation and bleeding (14% serious adverse events with high-dose therapy) 1, 2, 3
• Severe psychosis and delirium (particularly problematic in elderly patients) 1, 2
• Infectious complications including pneumonia and urinary tract infections 5, 3
• Hyperglycemia requiring insulin therapy 4

Timing and Prognostic Factors

Critical Time Windows

• Begin dexamethasone within 24 hours of diagnosis to prevent irreversible neurological injury 1
• Pretreatment ambulatory status is the strongest predictor of outcome: 96-100% of ambulatory patients remain ambulatory after treatment, but only 30% of non-ambulatory patients regain walking ability 4, 1
• Patients paraplegic for >24-48 hours have poor prognosis for recovery regardless of treatment 4, 1

Duration of Steroid Therapy

• Continue steroids for at least 24 hours before surgery or radiotherapy 4
• Taper rapidly over 10-14 days after definitive treatment begins 4, 1, 3
• Avoid prolonged courses beyond 2 weeks to minimize toxicity 4, 3

Integration with Definitive Treatment

Surgical Indications (Preferred in This Case)

• Surgery followed by radiotherapy is indicated for single-level compression, neurological deficits present <48 hours, and predicted survival ≥3 months 1
• Absolute surgical indications include bony retropulsion, bone fragments causing cord compression, or spinal instability 4, 1
• Administer radiotherapy postoperatively once healing has occurred 4, 1

Radiotherapy Regimen (If Surgery Contraindicated)

• Standard regimen: 30 Gy in 10 fractions 1
• Alternative for limited life expectancy: 8 Gy single fraction or 20 Gy in 5 fractions 1
• Pain relief may be delayed up to 2 weeks after radiotherapy initiation 1

Common Pitfalls to Avoid

• Do not delay steroid administration while awaiting MRI—start on clinical suspicion 1, 2
• Do not use high-dose steroids routinely in elderly patients—moderate doses are safer and nearly as effective 2, 3
• Do not continue steroids beyond 2 weeks without active tapering 4, 3
• Do not forget GI prophylaxis with proton pump inhibitors in elderly patients receiving steroids 4, 3
• Do not assume all myelopathy requires steroids—degenerative cervical myelopathy without acute compression does not benefit from steroids 6, 7
