Abstract
It is unclear whether brain atrophy in multiple sclerosis (MS) is associated with not only neuroinflammation but also systemic inflammation. Here we found that systemic inflammatory marker serum amyloid A (SAA) was moderately correlated with cortical volume in the patients with clinically isolated syndrome (CIS) and MS (r = −0.41, p = 0.019). SAA was also significantly correlated with T2 lesion volume (T2LV) even after adjusting for age, disease duration, and disease modifying therapy (p = 0.0050). Thus, systemic inflammation may be associated with cortical atrophy, possibly via an increase in the T2LV in patients with CIS/MS.
