Serum pleiotrophin levels in patients with multiple sclerosis

This prospective study compared serum pleiotrophin (PTN) levels in 168 MS patients across three disease subtypes (RRMS, PPMS, SPMS) against 41 healthy controls, finding significantly lower PTN levels in MS patients overall and in RRMS and SPMS subgroups. The findings suggest pleiotrophin may play a role in MS pathogenesis and could be investigated as a potential biomarker for certain disease phenotypes.
