This cross-sectional study of 78 women (38 with relapsing-remitting MS and 40 healthy controls) examined the relationship between depressive symptoms and sedentary behavior in MS patients. The research found significant associations between depression and increased sedentary time in women with MS, suggesting depression is a key factor contributing to reduced physical activity in this population.
This research examines whether gut microbiota composition could serve as a biomarker for diagnosing or predicting the course of multiple sclerosis. The study explores the relationship between bacterial communities in the intestine and MS disease progression, a recognized area of MS pathophysiology research.
A multicenter prospective study measured serum neurofilament light chain (sNfL) and glial fibrillary acidic protein (sGFAP) levels in 115 relapsing-remitting MS patients treated with ocrelizumab over one year to identify biomarkers predicting treatment response. Elevated baseline sNfL and sGFAP levels were associated with treatment failure due to ongoing inflammation, while most patients with progression without relapse showed low sNfL levels, suggesting these biomarkers may help predict which patients will achieve disease activity remission.
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.
Multiple sclerosis is a chronic autoimmune disorder of the central nervous system characterized by demyelination, inflammation, and progressive neuronal loss, presenting with diverse neurological symptoms including vision problems, sensory changes, weakness, and cognitive decline. The disease exhibits distinct clinical courses—relapsing-remitting (70-80% of cases), primary progressive (15-20%), and secondary progressive forms—with symptom onset typically in young adulthood and variable progression timelines.
