This study aimed to evaluate serum visfatin levels in treated patients with Relapsing-Remitting Multiple Sclerosis (RRMS) (PwMS) receiving disease-modifying therapy (DMT) and in naive MS patients (nMS), and to investigate their association with clinical characteristics, treatment status, and disease activity, including NEDA-3 status. The gene discussed is NAMPT; the disease is relapsing-remitting multiple sclerosis.
