We determined the extent of neuronal and glial cell destruction in 13 patients with herpes simplex type 1 (HSV-1) encephalitis, 15 patients with tick-borne encephalitis (TBE), and 20 noninfectious controls by analyzing the cerebrospinal fluid (CSF) concentrations of neurofilament protein (a marker of neurons, mainly axons), neuron-specific enolase (a marker of neurons, mainly somas), glial fibrillary acidic protein, and S-100 protein (markers of astrocytes). In addition, in patients with HSV-I encephalitis CSF samples were collected serially before 7, 8-14, and 18-49 days and 3-10 months after the onset of neurological symptoms. In the acute stage of HSV-1 encephalitis we found markedly higher CSF levels of the cell damage markers than in patients with TEE. The concentration of cell damage markers in HSV-I encephalitis decreased within 45 days after acute infection, except for neurofilament protein. The CSF concentrations of neurofilament protein increased during the second week, remained extremely high throughout the next month, and decrease thereafter. The changes in these markers of neuronal and glial destruction demonstrate the neuronal and astroglial cell damage during the first month after HSV-I encephalitis. In contrast, most patients with TEE had signs only of slight astrogliosis, except for two patients with paresis.
