Serum visfatin in multiple sclerosis: distinct profiles in healthy controls, naive patients, and treated RRMS

Across the three groups, visfatin levels differed significantly, with healthy controls showing the highest levels, followed by PwwMS, and the lowest levels observed in nMS patients. Lower serum visfatin levels in stable treated MS patients may reflect reduced inflammatory burden and effective immunomodulation. These findings suggest that visfatin could serve as a potential biomarker for treatment response in MS. Nevertheless, longitudinal studies including larger cohorts of naive patients are needed to clarify visfatin's regulatory role in MS pathophysiology and its interaction with disease-modifying therapies.
