Serum neurofilament light as biomarker of seizure-related neuronal injury in status epilepticus.

ABSTRACT: Biomarkers of neuronal damage in status epilepticus (SE) would be of great relevance for clinical and research purposes. In a retrospective cross-sectional study, serum neurofilament light chain (NfL) levels were measured in patients with SE (30 subjects), patients with drug-resistant epilepsy (30 subjects), and healthy controls (30 subjects). Serum NfL levels were higher in patients with SE (median = 26.15 pg/ml) compared to both epilepsy patients (median = 7.35 pg/ml) and healthy controls (median = 6.81 pg/ml; p < .001). In patients with SE, serum NfL levels showed a high correlation with cerebrospinal fluid (CSF) NfL (τ = .68, p < .001) as well as with CSF total tau (t-tau) levels (τ = .627, p < .001); they were higher in SE lasting >24 h (p = .013), in refractory/superrefractory SE (p
