Disease outcomes in AQP4-IgG+NMOSD are typically measured by relapse rate and disability. Using the MSBase, a multi-centre international registry, we aimed to examine the impact immunosuppressive therapies and patient characteristics as predictors of disease outcome measures in AQP4-IgG+NMOSD.MethodThis MSBase cohort study of AQP4-IgG+NMOSD patients examined modifiers of relapse in a multivariable proportional hazards model and expanded disability status score (EDSS) using a mixed effects model.Results206 AQP4-IgG+ patients were included (median follow-up 3.7 years). Age (hazard ratio [HR] = 0.82 per decade, p = 0.001), brainstem onset (HR = 0.45, p = 0.009), azathioprine (HR = 0.46, p

Authors: Kamal A, Hosny M, Abd Elwahab A, Shawki Kamal Y, Shehata HS, Hassan A Abstract BACKGROUND: Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system (CNS). Aberrant expression of transcription factor forkhead box P3 (FoxP3) has been suggested to underlie different immunological disorders as FOXP3 expression is essential for T regulatory cells (Tregs) to maintain their suppressive and anti-inflammatory functions and exert immunologic self-tolerance. Interleukin-35 (IL-35) is an important immunosuppressive cytokine that is produced mainly by CD4+ FOXP3+ Tregs. OBJECTIVES: To a...

Abstract Multiple sclerosis is a chronic inflammatory demyelinating disorder of the central nervous system that eventually leads to progressive neurodegeneration and disability. Recent findings highlighted the emerging role of each target of the endocannabinoid system in controlling the symptoms and disease progression of multiple sclerosis. Therefore, multi-target modulators of the endocannabinoid system could provide a more effective pharmacological strategy as compared to the single target modulation. In this work, N-cycloheptyl-1,2-dihydro-5-bromo-1-(4-fluorobenzyl)-6-methyl-2-oxo-pyridine-3-carboxamide (B2) w...

Abstract BACKGROUND: The human myelin oligodendrocyte glycoprotein-induced experimental autoimmune encephalomyelitis (huMOG-EAE) model, generates B-cell driven demyelination in mice, making it a suitable multiple sclerosis model to study B cell depletion. OBJECTIVES: We investigated the effect of subcutaneous anti-CD20 antibody treatment on huMOG-EAE gray matter (GM) pathology. METHODS: C57Bl/6, 8-week old mice were immunized with 200 huMOG1-125 and treated with 50 μg/mouse of anti-CD20 antibody (n = 16) or isotype control (n = 16). Serial brain volumetric 9.4 T MRI scans was performed at ...

Conclusions: Ferritin deficiency in MS patients is associated with an exacerbation of depressive disorders and a decline in quality of life. Symptoms of fatigue in MS patients are inversely proportional to mood and quality of life.

Basel, 10 September 2020 - Roche (SIX: RO, ROG; OTCQX: RHHBY) will present new ENSPRYNG ® (satralizumab) data on reducing relapse severity in the treatment of neuromyelitis optica spectrum disorder (NMOSD), a rare disease of the central nervous system. These data are being presented at MSVirtual2020, the 8th joint ACTRIMS-ECTRIMS meeting, in addition to longer-term efficacy data supporting the continued effect of ENSPRYNG on reducing the risk of NMOSD relapse, as well as its favourable benefit:risk profile.“The data for ENSPRYNG at MSVirtual2020 are promising and suggest it significantly reduces relapse severity ...

Multiple sclerosis (MS), an autoimmune disease of the central nervous system, generally starts as the relapsing remitting form (RRMS), but often shifts into secondary progressive MS (SPMS). SPMS represents a more advanced stage of MS, characterized by accumulating disabilities and refractoriness to medications. The aim of this study was to...

Conclusions: These data suggest that combined intravenous and intrathecal low-dose hUC-MSCs transplantation is safe and feasible in RRMS and NMO patients in the long term. The conclusion requires confirmation by future clinical trials in a larger cohort.

Comorbidities in patients with multiple sclerosis (MS) has become an area of increasing interest in the recent years. A comorbidity is defined as any additional disease that coexists in an individual with a given index disease and that is not an obvious complication of the index disease. The aim of this review is to describe the current evidence regarding the range of comorbidities in the population with MS reported in different countries and the current knowledge about the influence of comorbidities on the clinical features and therapeutic challenges in MS. Certain comorbidities are more prevalent in people with MS such a...

The most prominent pathological features of multiple sclerosis (MS) are demyelination and neurodegeneration. The exact pathogenesis of MS is unknown, but it is generally regarded as a T cell-mediated autoimmune disease. Increasing evidence, however, suggests that other components of the immune system, particularly B cells and antibodies, contribute to the cumulative CNS damage and worsening disability that characterize the disease course in many patients. We have previously described strongly elevated T cell reactivity to an extracellular domain of the most abundant CNS myelin protein, myelin proteolipid protein (PLP) in p...
