Self-reported physical health may predict RRMS disability worsening

People with relapsing-remitting multiple sclerosis (RRMS) who report better physical health are significantly more likely to see disability progression after three years, an observational study found. The findings suggest this patient-reported outcome measure may help predict long-term disability worsening in people with the condition. “Our findings…

More Inflammation Biomarkers in Spinal Fluid of PPMS Patients: Study

Individuals with primary progressive multiple sclerosis (PPMS) have significantly higher concentrations of specific inflammation biomarkers in their spinal fluid than healthy people, an exploratory study shows. For most biomarkers, levels in PPMS patients were comparable to or lower than those seen in people with relapsing-remitting multiple sclerosis (RRMS).

2 Biomarkers Seen as Best at Predicting Course of Relapsing MS

The levels of two cerebrospinal fluid (CSF) biomarkers, CHI3L1 and CXCL13, were significantly elevated in people with relapsing and progressive multiple sclerosis (MS) relative to control groups without this disease, and are most likely to predict how relapsing MS will progress, a study reported. Higher levels of these biomarkers were also…

Early Use of Tysabri Treatment Linked to Greater Benefits

Multiple sclerosis (MS) patients who started taking Tysabri (natalizumab) long after their diagnosis were found to have worsened disease progression. But those who began using it earlier showed less aggravated clinical and radiological outcomes of the disease than participants who started treatment later, a study showed. The study,…
