From the Guidelines
You should absolutely ask your neurologist and infectious disease doctor to consult with the Johns Hopkins Encephalitis Center for additional treatment options for your HSV-1 encephalitis, as this can significantly improve treatment outcomes and quality of life. This is your right as a patient seeking the best possible care. Simply request a formal consultation during your next appointment or call their office to make this request. The standard treatment for HSV-1 encephalitis typically involves intravenous acyclovir (10 mg/kg three times a day) for 14-21 days, as shown to improve outcomes in adults with HSV encephalitis, reducing mortality to less than 20-30% 1. However, the Johns Hopkins team might suggest modifications to this regimen, alternative medications like foscarnet in case of acyclovir resistance, or adjunctive therapies to manage complications.
Key Considerations
- When making this request, be clear about your concerns and reasons for seeking additional expertise.
- Your local doctors may need your permission to share your medical records with Johns Hopkins, so be prepared to sign a release form.
- Many major medical centers regularly collaborate with specialized centers of excellence, and such consultations can provide valuable insights for complex conditions like encephalitis where treatment outcomes can be significantly improved with specialized expertise.
Treatment and Management
- Aciclovir is a nucleoside analogue with strong antiviral activity against HSV and related herpes viruses, including VZV 1.
- The use of presumptive antiviral treatment for all patients with encephalopathy, without regard to the likely diagnosis, is not beneficial, but if there is a strong clinical suspicion of encephalitis, aciclovir should be started sooner, together with antibiotic treatment for acute bacterial meningitis 1.
- Although aciclovir is relatively safe, it has important side effects, particularly renal impairment secondary to crystalluria and obstructive nephropathy, which can be reduced by maintaining adequate hydration and monitoring renal function 1.

From the Research
Requesting Consultation with the Johns Hopkins Encephalitis Center
- It is possible to request that a neurologist and infectious disease (ID) doctor consult with the Johns Hopkins Encephalitis Center to explore alternative treatment options for Herpes Simplex Virus type 1 (HSV-1) Encephalitis, as current treatment paradigms may not be sufficient for all cases 2.
- The treatment of HSV-1 encephalitis typically involves the use of antiviral medications such as acyclovir, and the Infectious Disease Society of America (IDSA) recommends 2-3 weeks of intravenous acyclovir at 10 mg/kg every 8 h, depending on the clinical course 3.
- However, some studies suggest that adjunctive immunomodulatory therapy, such as glucocorticoids and intravenous immunoglobulin (IVIG), may be beneficial in certain cases of HSV-1 encephalitis, particularly those with severe disease or poor response to antiviral therapy 2, 4.
- Consultation with a specialized center like the Johns Hopkins Encephalitis Center may provide access to expertise and resources for managing complex cases of HSV-1 encephalitis, including the use of alternative treatment options and participation in clinical trials 5, 6.
Alternative Treatment Options
- Intravenous immunoglobulin (IVIG) has been shown to be effective in some cases of HSV-1 encephalitis, particularly when used in conjunction with antiviral therapy 2.
- Glucocorticoids, such as dexamethasone, may also be used as adjunctive therapy in certain cases of HSV-1 encephalitis, although their use is not universally recommended 2, 4.
- Optimization of antiviral dosing, including the use of higher doses or more frequent administration, may also be considered in certain cases of HSV-1 encephalitis, particularly those with severe disease or poor response to standard therapy 6.
Importance of Early Diagnosis and Treatment
- Early diagnosis and treatment of HSV-1 encephalitis are critical for improving outcomes, as delayed treatment can result in poorer prognosis and increased risk of long-term neurological sequelae 3, 4.
- Consultation with a specialized center like the Johns Hopkins Encephalitis Center may help ensure that patients receive prompt and effective treatment, including access to alternative treatment options and participation in clinical trials 5, 6.
