Comparative Study
[Japanese guidelines for the management of herpes simplex encephalitis; comparison with those from the International Management Herpes Forum].
Herpes simplex encephalitis (HSE) is still recognized as a severe sporadic encephalitis, although the mortality and morbidity rates have been decreased to 10% and 30%, respectively. This disease is diagnosed using clinical symptoms, CSF, EEG, CT, MRI, and virologic tests such as polymerase chain reaction (PCR) or enzyme immunosorbent assay (EIA). Early diagnosis and treatment are essential for HSE. ⋯ However, antiviral therapy may be discontinued if a negative CSF HSV PCR is obtained at > 72 hours after onset. A recent Japanese study shows the efficacy of a combination therapy of aciclovir and corticosteroid for this disease. Further prospective investigation is expected.
