Progression independent of relapse activity in relapsing multiple sclerosis: impact and relationship with secondary progression.

Objectives: We investigated the occurrence and relative contribution of relapse-associated worsening (RAW) and progression independent of relapse activity (PIRA) to confirmed disability accrual (CDA) and transition to secondary progression (SP) in relapsing multiple sclerosis (MS).

Methods: Relapsing-onset MS patients with follow-up > / = 5 years (16,130) were extracted from the Italian MS Registry. CDA was a 6-month confirmed increase in Expanded Disability Status Scale (EDSS) score.

Thrombotic Microangiopathy as a Life-Threatening Complication of Long-Term Interferon Beta Therapy for Multiple Sclerosis: Clinical Phenotype and Response to Treatment-A Literature Review.

Thrombotic microangiopathy (TMA) has been observed in some patients receiving interferon beta (IFNβ) therapy for relapsing-remitting multiple sclerosis, but little is known about its clinical features and outcomes. We searched the literature to identify cases with IFNβ-related TMA and assessed their pattern of organ involvement, the presence of prodromal manifestations, the treatments used, and the outcomes. Thirty-five articles met the inclusion criteria, and data of 67 patients were collected.

Hypogammaglobulinemia is associated with reduced antibody response after anti-SARS-CoV-2 vaccination in MS patients treated with antiCD20 therapies.

Background: COVID-19 vaccination is highly recommended to multiple sclerosis (MS) patients. Little is known about the role of patients' clinical and demographic characteristics in determining antibody response.

Methods: We evaluated safety and efficacy of anti-SARS-CoV-2 vaccines on 143 included MS patients.

Disease-Modifying Treatments and Time to Loss of Ambulatory Function in Patients With Primary Progressive Multiple Sclerosis.

Importance: Except for ocrelizumab, treatment options in primary progressive multiple sclerosis (PPMS) are lacking.

Objective: To investigate the effectiveness of DMTs on the risk of becoming wheelchair dependent in a real-world population of patients with PPMS.

Design, Setting, And Participants: This was a multicenter, observational, retrospective, comparative effectiveness research study.

Long-term Cognitive Outcomes and Socioprofessional Attainment in People With Multiple Sclerosis With Childhood Onset.

Background And Objectives: Patients with pediatric-onset multiple sclerosis (MS) can be especially vulnerable to cognitive impairment (CI) due to the onset of MS during a critical period for CNS development and maturation. The objective of this longitudinal study was to assess long-term cognitive functioning and socioprofessional attainment in the Italian pediatric MS cohort, previously assessed at baseline and 2 and 5 years.

Methods: The 48 patients evaluated at the 5-year assessment were screened for inclusion.

Progression is independent of relapse activity in early multiple sclerosis: a real-life cohort study.

Disability accrual in multiple sclerosis may occur as relapse-associated worsening or progression independent of relapse activity. The role of progression independent of relapse activity in early multiple sclerosis is yet to be established. The objective of this multicentre, observational, retrospective cohort study was to investigate the contribution of relapse-associated worsening and progression independent of relapse activity to confirmed disability accumulation in patients with clinically isolated syndrome and early relapsing-remitting multiple sclerosis, assessed within one year from onset and with follow-up ≥5 years (n = 5169).

Natalizumab treatment and pregnancy in multiple sclerosis: A reappraisal of maternal and infant outcomes after 6 years.

Objectives: To assess the impact of timing of natalizumab cessation/redosing on long-term maternal and infant outcomes in 72 out of the original 74 pregnancies of the Italian Pregnancy Dataset in multiple sclerosis (MS).

Methods: Maternal outcomes in patients who received natalizumab until conception and restarted the drug within 1 month after delivery ("treatment approach," (TA)) and patients who stopped natalizumab before conception and/or restarted the drug later than 1 month after delivery ("conservative approach," (CA)) were compared through multivariable Cox regression analyses. Pediatric outcomes were assessed through a semi-structured questionnaire.

Cerebrospinal Fluid IgM and Oligoclonal IgG Bands in Multiple Sclerosis: A Meta-Analysis of Prevalence and Prognosis.

The presence of intrathecal IgM synthesis (ITMS) has been associated with an aggressive multiple sclerosis (MS) clinical course. In the present systematic review, we aimed at assessing the prevalence of ITMS among different MS phenotypes. Moreover, we aimed at quantifying the risk of a second relapse in ITMS positive and oligoclonal IgG bands (OCGBs)-positive patients.

Effect of BDNF Val66Met polymorphism on hippocampal subfields in multiple sclerosis patients.

Brain-derived neurotrophic factor (BDNF) Val66Met polymorphism was shown to strongly affect BDNF function, but its role in modulating gray matter damage in multiple sclerosis (MS) patients is still not clear. Given BDNF relevance on the hippocampus, we aimed to explore BDNF Val66Met polymorphism effect on hippocampal subfield volumes and its role in cognitive functioning in MS patients. Using a 3T scanner, we obtained dual-echo and 3DT1-weighted sequences from 50 MS patients and 15 healthy controls (HC) consecutively enrolled.

Pregnancy in multiple sclerosis women with relapses in the year before conception increases the risk of long-term disability worsening.

Background: The influence of pregnancy on long-term disability in multiple sclerosis (MS) is still controversial.

Objective: To assess the risk of long-term disability worsening after pregnancy in MS women as compared with a propensity-score (PS) matched group of MS women without pregnancy.

Methods: In the setting of the Italian Pregnancy Dataset, MS patients with (pregnancy group (PG)) and without pregnancy (control group (CG)) were recruited.

The Brain-Derived Neurotrophic Factor Val66Met Polymorphism Can Protect Against Cognitive Impairment in Multiple Sclerosis.

Brain-derived neurotrophic factor (BDNF) is a member of the neurotrophin family, involved in neuronal survival and synaptic plasticity. The BDNF Val66Met polymorphism is known to reduce BDNF expression and secretion; its role in multiple sclerosis (MS) is poorly investigated. In this multicenter, retrospective study, we assessed the role of BDNF Val66Met polymorphism on cognitive and motor disability in MS patients consecutively referred to the University of Florence and the Hospital of Barletta.

Peak width of skeletonized mean diffusivity (PSMD) and cognitive functions in relapsing-remitting multiple sclerosis.

Peak width of skeletonized mean diffusivity (PSMD) is a new MRI marker, which has shown clinical relevance in some neurological conditions and, in preliminary data, in multiple sclerosis (MS). We aimed here to investigate, in a group of relapsing-remitting MS (RRMS) patients, the relationship between PSMD and cognitive performances, in comparison with other MRI measures. RRMS patients (n = 60) and normal controls (n = 15) underwent a 3 T MRI examination.

Disease-modifying drugs can reduce disability progression in relapsing multiple sclerosis.

An ever-expanding number of disease-modifying drugs for multiple sclerosis have become available in recent years, after demonstrating efficacy in clinical trials. In the real-world setting, however, disease-modifying drugs are prescribed in patient populations that differ from those included in pivotal studies, where extreme age patients are usually excluded or under-represented. In this multicentre, observational, retrospective Italian cohort study, we evaluated treatment exposure in three cohorts of patients with relapsing-remitting multiple sclerosis defined by age at onset: paediatric-onset (≤18 years), adult-onset (18-49 years) and late-onset multiple sclerosis (≥50 years).

A new paraplegin mutation in a patient with primary progressive multiple sclerosis.

Primary progressive multiple sclerosis (PPMS) presents with clinical signs of slowly progressive long tract dysfunction that can overlap with neurodegenerative disorders, such as hereditary spastic paraplegia (HSP). Herein, we present two siblings in whom we have identified a novel mutation in the paraplegin (SPG7) gene. The proband, a 49-year-old woman, presented with a five-year history of progressive spastic paraparesis and ataxia.

Experience with rituximab therapy in a real-life sample of multiple sclerosis patients.

Background: Multiple sclerosis (MS) is an autoimmune, neuroinflammatory, and neurodegenerative disease of the central nervous system. B cells have recently emerged as a promising target to significantly reduce inflammatory disease activity in MS, with successful trial studies using antiCD20 therapies. However, real-life data about safety and efficacy are limited.

Listening to the neurological teams for multiple sclerosis: the SMART project.

Objective: Aim of the research was to define the quality of life of Italian neurologists and nurses' professional caring for multiple sclerosis, to understand their living the clinical practice and identify possible signals of compassion fatigue.

Material And Methods: One hundred five neurologists and nurses from 30 Italian multiple sclerosis centres were involved in an online quali-quantitative survey on the organization of care, combined with the Satisfaction and Compassion Fatigue Test and a collection of narratives. Descriptive statistics of the quantitative data were integrated with the results obtained by the narrative medicine methods of analysis.

Prognostic role of intrathecal IgM synthesis in multiple sclerosis: Results from a clinical series.

Background: There is emerging evidence that intrathecal IgM synthesis (ITMS) is a risk factor for conversion to clinically defined multiple sclerosis (CDMS) in clinically isolated syndrome (CIS) patients.

Objectives: The objective of this study is to verify the prognostic role of ITMS as a risk factor for the second clinical attack in patients after the first demyelinating event.

Methods: Monocentric observational study performed on prospectively acquired clinical data and retrospective evaluation of magnetic resonance imaging (MRI) data.

[This corrects the article DOI: 10.1371/journal.pone.

Cognitive impairment in multiple sclerosis: An exploratory analysis of environmental and lifestyle risk factors.

Background: Many potentially modifiable risk factors for MS are investigated. It is not known, however, if these factors also apply to MS-related cognitive impairment (CI), a frequent consequence of MS.

Objective: The aim of our study was to assess risk factors for CI in MS patients, focusing on environmental exposures, lifestyle and comorbidities.

The clinical spectrum of anti-MOG associated acquired demyelinating disorders: Three case-reports.

Background: The spectrum of differential diagnosis of acquired demyelinating disorders of the central nervous system has been recently broadened. There is now growing evidence that supports anti-myelin oligodendrocyte antibodies associated demyelination as a distinct disease entity, with some clinical characteristics that somehow overlap those of Multiple Sclerosis (MS) and anti-AQP4+ Neuromyelitis Optica Spectrum Disorders (AQP4+NMOSD) but different pathogenesis and treatment strategies.

Summary: We hereby present 3 cases of anti-MOG+ patients with different disease courses - ranging from mild to severe - all presenting with Optic neuritis (ON) at the onset.

The dilemma of benign multiple sclerosis: Can we predict the risk of losing the "benign status"? A 12-year follow-up study.

Background: Definition of benign multiple sclerosis (BMS) remains controversial. Moreover, a sizeable proportion of classically defined BMS patients may be no longer benign (NLB) when re-assessed in the long-term. In a previous work, we found that after a five-year follow-up, a clinical score was able to identify patients at risk of losing their benign status.
