Real-World Experience with Diroximel Fumarate in Patients with Multiple Sclerosis: A Prospective Multicenter Study.

Background: Current literature and a real-world study suggest that diroximel fumarate (DRF) is safer than dimethyl fumarate (DMF) in the treatment of multiple sclerosis (MS). However, no real-world study to date has significantly addressed the efficacy of this treatment.

Objectives: This study aims to elucidate the safety, tolerability, and efficacy of DRF in a real-world setting, utilizing data from a Spanish national registry of patients commencing DRF therapy post-market introduction.

Clinical, genetic and neuropathological characterization of spinocerebellar ataxia type 37.

The autosomal dominant spinocerebellar ataxias (SCAs) consist of a highly heterogeneous group of rare movement disorders characterized by progressive cerebellar ataxia variably associated with ophthalmoplegia, pyramidal and extrapyramidal signs, dementia, pigmentary retinopathy, seizures, lower motor neuron signs, or peripheral neuropathy. Over 41 different SCA subtypes have been described evidencing the high clinical and genetic heterogeneity. We previously reported a novel spinocerebellar ataxia type subtype, SCA37, linked to an 11-Mb genomic region on 1p32, in a large Spanish ataxia pedigree characterized by ataxia and a pure cerebellar syndrome distinctively presenting with early-altered vertical eye movements.

Monitoring CD49d Receptor Occupancy: A Method to Optimize and Personalize Natalizumab Therapy in Multiple Sclerosis Patients.

Background: In natalizumab-treated relapsing-remitting MS (RRMS) patients, various extended interval dosing strategies are under evaluation to minimize severe treatment-associated side effects, mainly progressive multifocal leukoencephalopathy development. Up to now, it has not been presented any approach, even in form of assay design, to determine the optimal percentage of CD49d receptor occupancy (RO) associated with a favorable clinical, radiological, and immunological response.

Methods: A multiparametric quantitative flow cytometry method was settled to measure CD49d RO on peripheral blood lymphocytes.

Fatigue Improvement after Switching Multiple Sclerosis Treatment from Interferon-β to Glatiramer Acetate in Clinical Practice.

Background/aims: The immunomodulatory effect of glatiramer acetate may help in reducing multiple sclerosis (MS)-related fatigue; however, evidence to prove this notion especially after switching from another immunomodulatory therapy is limited. We assessed the 6-month effect of glatiramer acetate on MS-related fatigue in patients switching from interferon-β (IFN-β) in clinical practice.

Methods: This was an observational study including 54 patients with relapsing-remitting MS that showed moderate/severe fatigue primarily caused by MS before switching from IFN-β to glatiramer acetate and received glatiramer acetate for ≥6 months in daily practice.

Migraine treatment patterns and patient satisfaction with prior therapy: a substudy of a multicenter trial of rizatriptan effectiveness.

Background: Migraine is a common, chronic, often disabling neurologic condition that is underdiagnosed and undertreated.

Objective: We undertook this questionnaire-based study as a substudy of a multicenter trial of rizatriptan effectiveness. Our goal was to assess the history of acute migraine medication use and the relationship between different migraine medication regimens and patient satisfaction with prior therapy.
