Serum Neurofilament Light Chain in Multiple Sclerosis: Superiority of Age- and BMI-Corrected Z Scores/Percentiles Over Absolute Cutoff Values for Prediction of Treatment Response.

ABSTRACT:

Objective

Prognostication of disease course and prediction of treatment response in multiple sclerosis is an unmet need. We compared the performance of serum neurofilament light chain Z scores (age- and BMI-adjusted) with absolute concentrations for the prediction of response to disease-modifying therapy.

Methods

Observational cohort study including the first serum sample of participants after the start of fingolimod therapy. We estimated hazard ratios for future relapses comparing participants with high (upper quartile) versus lower neurofilament light chain levels, based on either absolute concentration or Z score cutoffs. We compared the prognostic/predictive performance of these two measures for the occurrence of new/enlarging T2w lesions in longitudinal MRI.
