Risk of disease relapse following COVID-19 vaccination in patients with AQP4-IgG-positive NMOSD and MOGAD.

Post-vaccination disease relapses have been reported in patients with MOGAD and AQP4-IgG+NMOSD. In this retrospective multicenter Italian study we assessed the frequency of relapses after SARS-CoV-2 vaccination. We included 56 cases: MOGAD, 30; AQP4-IgG+NMOSD, 26.

Ocrelizumab for the Treatment of Multiple Sclerosis: Safety, Efficacy, and Pharmacology.

The success of selective B-cells depleting therapies, as the anti-CD20 antibodies, in patients with multiple sclerosis (MS) has confirmed that B-cells are critical in the immune pathogenesis of the disease. Ocrelizumab, a humanized monoclonal antibody that selectively targets CD20+ B-cells, profoundly suppresses acute inflammatory disease activity, representing a highly effective therapy for relapsing-remitting multiple sclerosis (RRMS). It is also the first proven therapy able to slow disability progression in primary progressive multiple sclerosis (PPMS), particularly in patients with signs of acute radiological activity before being enrolled.

Early use of low dose tocilizumab in patients with COVID-19: A retrospective cohort study with a complete follow-up.

Background: Pneumonia with severe respiratory failure represents the principal cause of death in COVID-19, where hyper-inflammation plays an important role in lung damage. An effective treatment aiming at reducing the inflammation without preventing virus clearance is thus urgently needed. Tocilizumab, an anti-soluble IL-6 receptor monoclonal antibody, has been proposed for treatment of patients with COVID-19.

Switching to ocrelizumab in RRMS patients at risk of PML previously treated with extended interval dosing of natalizumab.

Discontinuation of natalizumab in patients with relapsing-remitting multiple sclerosis (RRMS) at risk of progressive multifocal leukoencephalopathy (PML) is associated with disease reactivation. Forty-two RRMS patients, who switched from an extended interval dose (EID) of natalizumab to ocrelizumab, underwent magnetic resonance imaging (MRI) and clinical monitoring during washout and after ocrelizumab starting. During the first 3 months, disease reactivation was observed in five (12%) patients; 6 months after ocrelizumab starting, no further relapses were recorded, and Expanded Disability Status Scale (EDSS) remained stable in 38 (90%) patients.

Diagnostic features of initial demyelinating events associated with serum MOG-IgG.

Background: Myelin oligodendrocyte glycoprotein (MOG)-IgG associated disorders are increasingly recognized as a distinct disease entity. However, diagnostic sensitivity and specificity of serum MOG-IgG as well as recommendations for testing are still debated.

Materials And Methods: Between October 2015 and July 2017 we tested serum MOG-IgG in 91 adult patients (49 females) with a demyelinating event (DE) not fulfilling 2010 McDonald criteria for MS at sampling, negative for neuromyelitis optica (NMO)-IgG and followed-up for at least 12 months.

Induction Versus Escalation in Multiple Sclerosis: A 10-Year Real World Study.

In this independent, multicenter, post-marketing study, we directly compare induction immunosuppression versus escalation strategies on the risk of reaching the disability milestone of Expanded Disability Status Scale (EDSS) ≥ 6.0 over 10 years in previously untreated patients with relapsing-remitting multiple sclerosis. We collected data of patients who started interferon beta (escalation) versus mitoxantrone or cyclophosphamide (induction) as initial treatment.

From high- to low-frequency administered interferon-beta for multiple sclerosis: a multicenter study.

Objectives: To investigate whether clinical and magnetic resonance imaging (MRI) outcomes of patients with multiple sclerosis (MS) who required a reduction of administration frequency of interferon-beta (IFNB) were similar to those of patients who did not.

Methods: We identified three subgroups of patients under treatment for 24 months with subcutaneous (sc) high-frequency IFNB-1a or -1b: those continuing to receive IFNB according to the drug label (recommended frequency group), those reducing the administration frequency of sc IFNB-1a or -1b (reduced frequency group), and those switched to once weekly intramuscular (im) IFNB (switched group). All patients were followed for further 24 months.

Interferon beta failure predicted by EMA criteria or isolated MRI activity in multiple sclerosis.

Objective: The objective of this paper is to investigate four-year outcomes of interferon beta (IFNB)-treated patients with multiple sclerosis (MS) according to their clinical or magnetic resonance imaging (MRI) activity status at first year of treatment.

Methods: A total of 370 patients with MS duration ≤5 years before IFNB start were followed-up for four years. The optimal threshold for one-year MRI activity that more accurately predicted subsequent relapses or disability worsening was identified.

Balance deficit with opened or closed eyes reveals involvement of different structures of the central nervous system in multiple sclerosis.

Objective: To evaluate whether balance deficit in patients with multiple sclerosis (MS), as assessed with eyes opened (EO) and closed (EC), is associated with damage of different structures of the central nervous system (CNS).

Methods: Fifty patients with MS and 20 healthy controls (HCs) underwent static posturography to calculate the body's center of pressure displacement (COP path) with EO and EC. They were scanned using a 3.

Advances in the treatment of relapsing-remitting multiple sclerosis - critical appraisal of fingolimod.

Multiple sclerosis (MS) is a chronic inflammatory disorder of the central nervous system, traditionally considered to be an autoimmune, demyelinating disease. Based on this understanding, initial therapeutic strategies were directed at immune modulation and inflammation control. At present, there are five licensed first-line disease-modifying drugs for MS in Europe, and two second-line treatments.
