Abstract

The aim of our study was to determine whether high doses of intravenous methylprednisolone have significant impact on immune parameters during the multiple sclerosis (MS) exacerbations. Peripheral blood of 32 MS patients was evaluated, using two-color flow cytometry before glucocorticosteroids and after 7 days from starting therapy. Significant increase of B cells, decrease of NK cells and monocytes producing IL-8 were observed after treatment. IL-8 is one of the cytokines responsible for blood-brain-barrier disruption and migration of immune cells to the central nervous system; in this aspect, explaining glucocorticosteroid effects during MS exacerbations.
