Management of Dengue Encephalitis
Diagnostic Evaluation and Management
- Patients with suspected dengue encephalitis require immediate hospitalization with access to intensive care for airway protection, ventilatory support, and management of increased intracranial pressure, as recommended by the American Academy of Neurology 1
- Obtain urgent neuroimaging (MRI preferred, CT if unavailable) to assess for cerebral edema and intracranial hemorrhage, and consider lumbar puncture unless contraindicated by increased intracranial pressure, as suggested by the American College of Emergency Physicians 1
Specialist Consultation and Multidisciplinary Care
- Obtain neurological specialist opinion within 24 hours of admission, and involve infectious disease specialists, neurologists, and intensive care teams in the management of dengue encephalitis, as recommended by the Infectious Diseases Society of America 1
Follow-up and Rehabilitation
- All patients require assessment for rehabilitation, as neurological sequelae may not be immediately apparent at discharge, and arrange outpatient follow-up with plans for ongoing therapy before discharge, as suggested by the American Academy of Physical Medicine and Rehabilitation 1
- Monitor for long-term complications including anxiety, depression, and behavioral problems, which may occur in patients with a history of dengue encephalitis, as reported by the World Health Organization 2
Management of Dengue Encephalitis
Multidisciplinary Care
- The management team for dengue encephalitis should include multidisciplinary input from neurologists, infectious disease physicians, virologists, neurophysiologists, neuroradiologists, and intensive care staff 3
Treatment Approach
- The Centers for Disease Control and Prevention, as reflected in MMWR Recommendations and Reports, advise against the routine use of corticosteroids, interferon alpha-2a, ribavirin, minocycline, or other antivirals for flavivirus encephalitis, as controlled clinical trials have demonstrated no improvement in clinical outcomes 4, 5
Supportive Care
- Early aggressive supportive management is crucial in reducing mortality from dengue encephalitis, which has a 20-30% case-fatality ratio, and supportive care should not be delayed while awaiting definitive virological diagnosis 4, 5
