Experience with tocilizumab in patients with neuromyelitis optica spectrum disorders.

Introduction: Neuromyelitis optica spectrum disorders (NMOSD) are immune-mediated inflammatory disorders of the central nervous system involving astrocytes, B lymphocytes, anti-aquaporin 4, and such inflammatory mediators as interleukin-6. Several immunosuppressants are used in their treatment. Tocilizumab, an interleukin-6 receptor antagonist, may be a treatment option.

Generation of RRMS and PPMS specific iPSCs as a platform for modeling Multiple Sclerosis.

The advent of cellular reprogramming technology converting somatic cells into induced pluripotent stem cells (iPSCs) has revolutionized our understandings of neurodegenerative diseases that are otherwise hard to access and model. Multiple Sclerosis (MS) is a chronic demyelinating, inflammatory disease of central nervous system eventually causing neuronal death and accompanied disabilities. Here, we report the generation of several relapsing-remitting MS (RRMS) and primary progressive MS (PPMS) iPSC lines from MS patients along with their age matched healthy controls from peripheral blood mononuclear cells (PBMC).

Prevention of rebound effect after natalizumab withdrawal in multiple sclerosis. Study of two high-dose methylprednisolone schedules.

Background: Natalizumab (NTZ) is a disease-modifying treatment (DMT) in multiple sclerosis (MS) whose discontinuation can produce a "rebound effect", consisting of severe clinical deterioration and/or evidence of disease reactivation on magnetic resonance imaging (MRI).

Objective: To analyze the efficacy of two treatment schedules with intravenous methylprednisolone (IVMP) administered during the washout period of natalizumab (i.e.

Pulse immunosuppressive therapy for multiple sclerosis during the SARS-CoV-2 lockdown de-escalation plan: Safety algorithm.

Introduction: The COVID-19 pandemic is changing approaches to diagnosis, treatment, and care provision in multiple sclerosis (MS). During both the initial and peak phases of the epidemic, the administration of disease-modifying drugs, typically immunosuppressants administered in pulses, was suspended due to the uncertainty about their impact on SARS-CoV-2 infection, mainly in contagious asymptomatic/presymptomatic patients. The purpose of this study is to present a safety algorithm enabling patients to resume pulse immunosuppressive therapy (PIT) during the easing of lockdown measures.
