Temporal association of sNfL and gad-enhancing lesions in multiple sclerosis.
Multiple sclerosis (MS) is an autoimmune demyelinating disorder, which is characterized by relapses and remissions. Serum neurofilament light chain (sNfL) is an emerging biomarker of disease activity but its clinical use is still limited. In this study, we aim to characterize the temporal association between sNfL and new clinical relapses and new gadolinium-enhancing (Gd+) lesions. ⋯ Our findings support sNfL as a marker of clinical relapses and Gd+ lesions. sNfL peaks in a 3-month window around Gd+ lesions. sNfL shows promise as a biomarker of neurological inflammation and possibly of simultaneous Gd+ lesions during a clinical relapse.
