- Five patients with chronic progressive multiple sclerosis (MS) and three control patients with lumbar disc herniation were treated with dexamethazone during 14 days. The effect on peripheral blood T-cell subsets and on the proliferative response of peripheral blood mononuclear cells (PBMC) to pokeweed mitogen (PWM) and anti-mu antibody was analyzed. Before treatment, the proportion of CD3+ and CD4+ PBMC was similar in MS and control patients, but the proportion of CD8+ and DR+ PBMC was lower and the PBMC were less responsive to anti-mu stimulation in MS patients compared to controls. Steroid treatment induced reversible granulocytosis and lymphocytosis. CD3+ and CD4+ cells increased and DR+ cells decreased in MS patients but not in controls. Proliferation of anti-mu stimulated PBMC increased in MS-patients during the two weeks of treatment, but decreased in controls. The enhancement in the MS patients of pre-existing immune abnormalities suggests that a cautious attitude is warranted in the use of steroid treatment in chronic progressive MS.
