Is Lyme neuroborreliosis, even in its early phase, a parenchymatous disorder in the central nervous system (CNS), and not merely a meningitic process? We quantified cerebrospinal fluid (CSF) levels of four nerve and glial cell marker proteins in Lyme neuroborreliosis patients with pretreatment durations of 7-240 days. All 23 patients had meningoradiculitis, and six had objective signs of encephalopathy. Glial fibrillary acidic protein (GFAp) pretreatment levels in CSF, and the light subunit of neurofilament protein (NFL) levels were related to clinical outcome and declined significantly after treatment (P < 0.001 and P < 0.01, respectively). NFL was detectable in 11 out of 22 patients, and pre- and post-treatment NFL levels were associated with the duration of neurological symptoms within 100 days prior to treatment. Neuron-specific enolase (NSE) concentrations also decreased after therapy (P < 0.001), while CSF levels of glial S-100 protein remained unchanged. The pretreatment duration of disease was related to postinfectious sequelae. GFAp, NSE and NFL levels in CSF are unspecific indicators of astroglial and neuronal involvement in CNS disease. The findings in the present study are in agreement with the hypothesis that early and late stages of Lyme neuroborreliosis damage the CNS parenchyma.

BACKGROUND - To evaluate cerebrospinal fluid (CSF) markers for neuronal degeneration and demyelination in idiopathic normal pressure hydrocephalus (INPH), subcortical arteriosclerotic encephalopathy (SAE), and neurologically healthy subjects. METHODS - Lumbar CSF concentrations of sulfatide, neurofilament protein light (NFL), total-tau (T-tau), hyperphosphorylated tau (P-tau), and beta-amyloid(1-42) (Abeta42) were analyzed in 62 INPH patients, 26 SAE patients, and 23 neurologically healthy controls. In INPH patients, samples before and after shunt surgery were analysed. RESULTS - The CSF concentration of NFL was elevated in INPH and SAE compared with the controls, and levels of T-tau, P-tau, and Abeta42 were lower in INPH compared with SAE and controls. No difference was seen for sulfatide. All markers except Abeta42 were significantly elevated after shunt surgery. CONCLUSIONS - The most striking finding was the power of the combined pattern of NFL, P-tau, and Abeta42 in distinguishing between the clinical diagnoses of INPH, SAE, and neurologically healthy elderly.
