Objectives: Multiple sclerosis (MS) is a chronic CNS autoimmune disease characterized by demyelination and neurodegeneration. Chemokines regulate leukocyte migration and inflammation in MS. In the present study, we evaluated selected chemokine levels in the cerebrospinal fluid of patients with multiple sclerosis diagnosed de novo compared to healthy controls.Methods: We measured EOTAXIN, IP-10, MCP-1, MIP-1a, MIP-1b and RANTES in the cerebrospinal fluid of 118 patients with de novo RRMS and 112 controls, analyzing correlations with time from symptom onset to diagnosis and changes in MRI.Results: Higher levels of EOTAXIN, IP-10, MIP-1B and RANTES, and lower MCP-1 were observed in MS patients compared to controls. MIP-1A did not show statistical significance. EOTAXIN and IP-10 concentrations increased with time. RANTES concentration correlated positively with T2 changes in MRI of the cervical spine, and EOTAXIN concentration correlated negatively with gadolinium (Gd+) changes in the cervical spine. There was no correlation with changes in the thoracic spine or brain.Conclusions: Chemokines play a significant role in the early phase of MS by influencing inflammatory activity. They may represent potential therapeutic targets for the treatment of this disease.
