To determine the immunological effects of high-dose intravenous methylprednisolone (IVMP) and elucidate immune measurements used for evaluation of its therapeutic effect, we analyzed lymphocyte subsets and humoral immune parameters in peripheral blood and cerebrospinal fluid (CSF) samples, before and within 2 weeks of treatment during 19 acute exacerbations in 16 relapsing-remitting multiple sclerosis (MS) patients.

In addition to decreases in CSF albumin and IgG levels, treatment resulted in an increase of CD8(+)CXCR3(+) cells as well as a decrease in CD4(+) subsets expressing CD25, CD29, and CCR4 in the CSF.

Further, the percentage of circulating CD4(+)CXCR3(+) Th1 cells also decreased.

Clinical improvement was achieved following 15 of the 19 treatment occasions.

Early (<2 weeks of treatment) clinical improvement was significantly associated with a decrease in CSF CD4(+)CD29(+) helper inducer T cells, whereas they were nearly unchanged in four patients who showed no improvement.

Changes in other parameters following IVMP treatment were not different between the responder and non-responder groups.
