THE EFFECT OF CHEMOKINE CXCL-13 ON THE CLINICAL AND FUNCTIONAL STATUS OF PATIENTS WITH MULTIPLE SCLEROSIS IN REMISSION
Introduction. CXCL-13 can be involved in the development of MS, and its level in peripheral blood may have diagnostic and / or prognostic significance. The purpose of this study is to assess the level of CXCL-13 in serum and its relationship with the clinical and functional state of patients with remitting MS in remission. Materials and methods. The study involved 67 patients (28 men and 39 women) with a relapsing MS in remission. All patients were examined by scales and questionaries EDSS, Multiple Sclerosis Functional Composite, Multiple Sclerosis Impact Scale 29, Fatigue Severity Scale. On the day of the clinical examination venous blood samples were taken from patients and healthy donors, serum was isolated, and the level of CXCL-13 was assessed by enzyme immunoassay method. Results and discussion. It was revealed that CXCL-13 in the serum in patients with MS was significantly lower than in healthy volunteers. A relationship was found between serum CXCL-13 and the severity of neurological deficit according to EDSS, with walking speed of 25 feet, with an assessment of the quality of life and fatigue. Conclusions. Despite the association of CXCL-13 with the clinical and functional state of MS patients, at present time this chemokine cannot be considered to be a diagnostic or prognostic marker in MS patients.
