Despite the availability of multiple disease-modifying therapies for relapsing multiple sclerosis (MS), there remains a need for highly efficacious targeted therapy with a favorable benefit-risk profile and attributes that encourage a high level of treatment adherence. Daclizumab is a humanized monoclonal antibody directed against CD25, the α subunit of the high-affinity interleukin 2 (IL-2) receptor, that reversibly modulates IL-2 signaling. Daclizumab treatment leads to antagonism of proinflammatory, activated T lymphocyte function and expansion of immunoregulatory CD56(bright) natural killer cells, and has the potential to, at least in part, rectify the imbalance between immune tolerance and autoimmunity in relapsing MS...

Multiple sclerosis (MS) is a chronic, autoimmune, inflammatory, demyelinating disease of the central nervous system. MS is increasingly recognized in the pediatric population, and it is usually diagnosed around 15 years of age. The exact etiology of MS is still not known, although autoimmune, genetic, and environmental factors play important roles in its development, making it a multifactorial disease. The disease in children almost always presents in the relapsing-remittent form. The therapy involves treatment of relapses, and immunomodulatory and symptomatic treatment...

We report that B cells from patients with RRMS have decreased endogenous IFN-β secretion and deficient IFN receptor (IFNAR)1/2 and TLR7 gene expression in comparison to healthy controls (HCs), which may contribute to disregulation of cytokine secretion by B cells. We propose that TLR7 and TLR9 stimulation with loxorubin (LOX) and CpG, in combination with exogenous IFN-β may effectively reconstitute endogenous IFN-β production deficit and induce the secretion of immunoregulatory cytokines by B cells. Both LOX/IFN-β and CpG/IFN-β in-vitro treatments of B cells from RRMS patients induced higher endogenous IFN-β gene expression in comparison to the exogenous IFN-β alone...

Further studies are needed to determine the role of retinal optical coherence tomography (OCT) in non-optic neuritis (ON) eyes of patients with early MS. The objective of this study is to explore the relationship between retinal layers' thickness and cognitive as well as physical disability in patients with the early RRMS. Participants in this cross-sectional study were adults with early RRMS, stable on interferon beta-1a, or fingolimod therapy, and without a history of ON in one or both eyes. Patients were evaluated clinically, underwent a battery of cognitive tests, and a retinal OCT scan which was also performed on a group of healthy age- and gender-matched controls...

INTRODUCTION: Patients with multiple sclerosis (MS) generally undergo long-term treatment with disease-modifying therapies (DMTs). In the US, patients taking glatiramer acetate, interferon beta-1a, or interferon beta-1b, typically use a mechanical autoinjector. Recent survey results have shown that using an electronic autoinjector, such as BETACONNECT™ (Bayer Pharma AG) for interferon beta-1b/Betaseron(®) (Bayer Pharma AG) may reduce injection discomfort and increase patient satisfaction with treatment...
