RESUMEN
Natalizumab (TYSABRI®) was the first high-efficacy monoclonal antibody disease-modifying therapy (DMT) approved as a monotherapy for the treatment of adults with relapsing forms of multiple sclerosis (MS), including clinically isolated syndrome, relapsing-remitting MS, and active secondary progressive MS. Because natalizumab is administered by intravenous infusion, infusion nurses play a key role in the care of natalizumab-treated patients. In the 16 years since approval, substantial data have been gathered on the long-term, real-world effectiveness and safety of natalizumab. This article provides a synopsis of this data, as well as practical information for optimizing patient care. This includes information on strategies to mitigate the risk of progressive multifocal leukoencephalopathy in natalizumab-treated patients, natalizumab use during pregnancy, and use with vaccines. It also includes guidance on the preparation and administration of natalizumab and monitoring of natalizumab-treated patients.

Dimethyl fumarate (Tecfidera™) is an effective therapy for relapsing forms of multiple sclerosis (MS). Our study suggests that this drug may have immunosuppressive properties evidenced by significant sustained reduction in CD8 lymphocyte counts and, to a lesser extent, CD4 lymphocyte counts. This observation is relevant in light of the recent case of progressive multifocal leukoencephalopathy in a patient receiving this drug.
