Multiple sclerosis : clinical and laboratory research
-
Daclizumab is a humanized monoclonal antibody (mAb) that blocks the interleukin-2 receptor alpha subunit (IL-2R-alpha chain; CD25) expressed on activated T cells leading to the inhibition of T-cell expansion, thus strongly reduces brain inflammation in patients with multiple sclerosis (MS). Another mechanism is significant expansion of CD56 (bright) natural killer (NK) cells that in turn inhibit T-cell survival. ⋯ At the Partners MS center, we have been using Daclizumab in an open-label fashion in patients who fail first line therapy or non-standard immunosuppressive treatment. Our aim was to assess its safety and tolerability in our patient population.

Clinical Trial
Early highly aggressive MS successfully treated by hematopoietic stem cell transplantation.
During the last 15 years, high-dose chemotherapy with autologous hematopoietic stem cell transplantation (HSCT) has globally been performed for severe multiple sclerosis (MS). Most patients have been in progressive phase with long disease duration. As a rule, treatment effect has been minor or moderate. ⋯ This small series of patients with "malignant" relapsing-remitting MS suggests HSCT to be an effective treatment option for this relatively rare disease course. It further suggests that future criteria for HSCT in MS should be close to the present ones.
