Multiple sclerosis (MS) is a chronic inflammatory degenerative disease of the central nervous system
.
In the course of the disease evolution of 10-15 years, the progressive irreversible disability that occurs in most patients is largely independent of acute focal inflammatory activities, including recurrence and new MRI damage
.
Neurofilament (NFL) is a biomarker of nerve axon damage.
It increases during the recurrence of RRMS patients and is accompanied by the appearance of new T2/GE MRI lesions.
It returns to baseline within a few months after the acute event, and After receiving DMT, it began to decline
.
In existing cross-sectional studies, the NFL is associated with measures of disease severity, such as the Extended Disability Severity Score (EDS)
.
Recently, some researchers discussed the possibility of serum neurofilament protein (NFL) in relapsing remitting multiple sclerosis (RRMS) patients after applying natalizumab to reflect or predict the progress of the disease
A total of 89 subjects were included in the study
.
The median follow-up time after Natalizumab treatment was 5.
2 years (IQR 4.
- From the first year to the last follow-up, 28/89 (31.
In this study cohort, the NFL failed to capture or predict the progression of the disease, which was largely independent of the clinical or imaging changes of acute focal inflammatory activity
