Elevated CSF free kappa light chains (FKLCs) may predict disability in multiple sclerosis (MS). We reviewed records of 57 patients with MS with 15-year median follow-up for correlations of disability and CSF FKLCs. Levels ≥ 1.53 μg/mL predicted progression to need for ambulatory assistance during follow-up (specificity 87.5%, positive predictive value 88.9%) or within 10 years (specificity 78.6%, positive predictive value 66.7%).
