Objective: This study was conducted to identify a biomarker for multiple sclerosis (MS) that can be used as a predictor of relapse and disability. Materials and Methods: Sera of 26 consecutive relapsing-remitting MS (RRMS) patients were screened for switch-associated protein 70 (SWAP-70) antibody, which was previously identified by protein macroarray. The serum levels of several cytokines, chemokines and soluble adhesion molecules related to MS attacks were measured by enzyme-linked immunosorbent assay (ELISA). A possible correlation was sought among levels of SWAP-70 antibody, measured humoral factors and disability scores. Results: ELISA studies showed high-titre SWAP-70 antibodies in 16 (61.5%) RRMS sera obtained during the attack period and 9 (34.6%) sera obtained during remission. There was a significant inverse correlation between SWAP-70 antibody levels and expanded disability status scale scores, CXCL10, soluble VCAM-1, CXCL13 and soluble VLA-4 levels. Conclusion: Our results showed that SWAP-70 antibodies could potentially be utilized as relapse and prognostic biomarkers in MS. Whether or not SWAP-70 antibodies have any effect on disease mechanisms requires further investigation. (C) 2014 S. Karger AG, Basel
