Management of Stroke Associated with Epstein-Barr Virus Infection
Patients with stroke associated with Epstein-Barr virus infection should receive standard acute stroke management with additional consideration for antiviral therapy and management of potential hypercoagulable state induced by the viral infection.
Acute Management
Initial Assessment and Imaging
- Immediate cerebral CT scan to rule out hemorrhagic stroke 1
- Complete neurovascular imaging (CT angiography or MR angiography) to assess for large vessel occlusion 1
- Transthoracic and transesophageal echocardiography to evaluate for potential infective endocarditis or other cardiac sources of embolism 1
- MRI with diffusion-weighted imaging to better characterize ischemic lesions and detect microemboli
Acute Reperfusion Therapy
- For ischemic stroke with large vessel occlusion:
- For patients without large vessel occlusion:
- Standard stroke management with blood pressure control and supportive care 1
Specific Management for EBV-Associated Stroke
Antiviral Therapy
- Consider antiviral therapy (acyclovir or ganciclovir) in cases with evidence of active EBV infection, especially with neurological manifestations beyond stroke 2, 3
- Duration of therapy typically 14-21 days, guided by clinical response and viral load monitoring
Hypercoagulability Management
- Evaluate for EBV-induced hypercoagulable state:
- Check protein C and protein S levels 4
- Monitor coagulation parameters (PT, aPTT, fibrinogen, D-dimer)
- For patients with confirmed hypercoagulable state:
Inflammatory Response Management
- Monitor for signs of hemophagocytic syndrome (persistent fever, cytopenias, hyperferritinemia) 2
- Consider corticosteroid therapy for severe inflammatory manifestations, particularly with cerebellitis or encephalitis 3
- Immunoglobulin therapy may be considered in cases with severe neurological manifestations not responding to other treatments
Monitoring and Follow-up
Neurological Monitoring
- Daily neurological assessments to detect early deterioration 1
- Repeat neuroimaging if clinical deterioration occurs to rule out:
- Hemorrhagic transformation
- New ischemic lesions
- Development of cerebral edema
EBV Monitoring
- Serial EBV viral load measurements to assess response to therapy
- Monitor for development of other EBV-related complications:
Long-term Management
Secondary Prevention
- Long-term antiplatelet therapy (typically aspirin) for patients with ischemic stroke 1
- Consider extended antiviral therapy in cases of chronic active EBV infection 3
- Regular neurological follow-up to monitor for recurrent events or development of other neurological complications
Rehabilitation
- Early initiation of rehabilitation services based on deficit pattern
- Multidisciplinary approach including physical, occupational, and speech therapy as needed
Special Considerations
Cerebral Hemorrhage
- In cases of EBV-associated cerebellar or cerebral hemorrhage 6:
- More cautious approach to anticoagulation and antiplatelet therapy
- Close monitoring for signs of increased intracranial pressure
- Consider neurosurgical consultation for significant hemorrhage with mass effect
Pediatric Patients
- Children with EBV-associated stroke may develop unique manifestations:
- More aggressive monitoring for long-term neurological sequelae is warranted
Pitfalls and Caveats
- Do not delay standard stroke management while awaiting confirmation of EBV infection
- Be aware that EBV can cause both ischemic and hemorrhagic stroke presentations
- Consider the possibility of EBV-associated infective endocarditis as a source of embolic stroke
- Monitor for development of post-infectious autoimmune complications that may require immunomodulatory therapy
- Recognize that EBV reactivation, not just primary infection, can lead to neurological complications 3
