Key clinical point: Serum neurofilament light chain (sNfL) could serve as an effective prognostic biomarker for long-term disability progression in patients with progressive multiple sclerosis (PMS).
Major finding: An sNfL value of >10.2 pg/mL at baseline differentiated long-term progressors and nonprogressors with a sensitivity of 75% and a specificity of 67% (adjusted odds ratio [aOR] 7.8; P = .01), and an increase of >5.1 pg/mL in the sNfL value from baseline to 6 years differentiated long-term progressors and nonprogressors with a sensitivity of 71% and a specificity of 86% (aOR 49.4; P = .008).
Study details: This was a 6-year prospective observational cohort study that included 51 patients with PMS who had participated in a 2-year phase 2, randomized, placebo-controlled trial of interferon-beta.
Disclosures: No external funding was received for this study. The authors declared no conflicts of interests.
