In 2013, the "MS in the 21st Century" (MS21) initiative established a consensus statement for multiple sclerosis (MS) standards of care, with an overall vision including "Full access to personalised treatment, with reimbursement, to achieve freedom from disease." This update considers progress made since 2013 and priority areas for further improvement. A Delphi process with two rounds of anonymised voting was used to develop updated consensus statements based on three key themes: (1) optimising current MS care provision; (2) facilitating shared decision-making and patient education; and (3) continuing MS research and development. Voting panels (n=30), including people living with MS (PwMS), MS patient advocacy group (PAG) representatives and healthcare professionals (HCPs) indicated agreement using a sliding scale [1 (strongly disagree) to 5 (strongly agree)] and free-text feedback. Statements were revised after each voting round, with the consensus threshold set a priori as≥75% agreement. There was a 70% response rate at each round of voting, with respondents representing 13 countries. Seven original principles were expanded to 14, with emerging themes including unmet care needs in ageing PwMS, MS prevention, and treatments for progressive MS and remyelination. The top priority for both HCPs and PwMS/PAG representatives was "access to quick and decisive treatment after diagnosis." For PwMS to be unburdened by symptoms, professionals and stakeholders within the MS community should work together to meet the updated MS21 vision, including access to appropriate care, greater PwMS involvement in decisions, and further research and development to address unmet needs in MS.

ABSTRACTBackgroundComorbidities occur in aquaporin‐4 antibody‐positive neuromyelitis optica spectrum disorder (AQP4‐NMOSD), myelin oligodendrocyte glycoprotein antibody‐associated disease (MOGAD), and double seronegative NMOSD (DN‐NMOSD), potentially contributing to a less favorable disease course.ObjectivesTo characterize comorbidities in AQP4‐NMOSD, MOGAD, and DN‐NMOSD and assess their association with optic neuritis (ON) outcomes by optical coherence tomography (OCT) in AQP4‐NMOSD.MethodsFour hundred and forty‐two participants from the CROCTINO cohort were evaluated for comorbidities.ResultsIn AQP4‐NMOSD patients (n = 360), 43.5% (n = 161) had comorbidities, equally divided between single and multiple. In MOGAD (n = 49), 40.8% had comorbidities, with 75% (n = 15) single and 25% (n = 5) multiple. In DN‐NMOSD (n = 33), 36.4% (n = 12) had comorbidities equally split. AQP4‐NMOSD patients had more multiple comorbidities (50%, n = 81/161) than MOGAD (25%, n = 5/20, p = 0.03) and more autoimmune disorders (AID) (40.4%, n = 65) than MOGAD (20%, n = 4, p = 0.09) and DN‐NMOSD (none, p = 0.004). Cardiovascular comorbidities and related risk factors (CVC/RF) occurred in 34.8% (n = 56) of AQP4‐NMOSD, 50% (n = 10) of MOGAD, and 33.3% (n = 4) of DN‐NMOSD. Expanded Disability Status Scale was higher in MOGAD (3.0 vs. 2.0, p = 0.006) and DN‐NMOSD (5.0 vs. 2.0, p = 0.008) with comorbidities. AQP4‐NMOSD patients with CVC/RF had higher ON relapse rates than those with AID (1.06 ± 3.33 vs. 0.49 ± 0.98, p < 0.001). OCT revealed reduced inner nuclear layer thickness in AQP4‐NMOSD with comorbidities compared to non‐comorbidity (B = −1.52, p = 0.047), more pronounced with CVC/RF (B = −2.96, p = 0.009).ConclusionComorbidities are frequent in AQP4‐NMOSD and MOGAD and are associated with ON frequency and disability. These findings highlight the need for proactive comorbidity management to improve patient care.

Abstract Multiple sclerosis (MS) is a leading cause of neurological disability in adults. Heterogeneity in MS clinical presentation has posed a major challenge for identifying genetic variants associated with disease outcomes. To overcome this challenge, we used prospectively ascertained clinical outcomes data from the largest international MS Registry, MSBase. We assembled a cohort of deeply phenotyped individuals with relapse-onset MS. We used unbiased genome-wide association study and machine learning approaches to assess the genetic contribution to longitudinally defined MS severity phenotypes in 1,813 individuals. Our results did not identify any variants of moderate to large effect sizes that met genome-wide significance thresholds. However, we demonstrate that clinical outcomes in relapse-onset MS are associated with multiple genetic loci of small effect sizes. Using a machine learning approach incorporating over 62,000 variants and demographic variables available at MS disease onset, we could predict severity with an area under the receiver operator curve (AUROC) of 0.87 (95% CI 0.83 – 0.91). This approach, if externally validated, could quickly prove useful for clinical stratification at MS onset. Further, we find evidence to support central nervous system and mitochondrial involvement in determining MS severity.

The availability of vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), provides hope towards mitigation of the coronavirus disease 2019 (COVID-19) pandemic. Vaccine safety and efficacy has not been established in individuals with chronic autoimmune diseases such as multiple sclerosis (MS). Anecdotal reports suggest that the vaccines may be associated with brain, spinal cord, peripheral nervous system, and cardiac inflammation. Based on the high morbidity and unpredictable course of COVID-19, and the need to achieve herd immunity, vaccination has been recommended for patients with MS. We report clinical and MRI features of seven individuals who received the Moderna (n = 3) or Pfizer (n = 4) SARS-CoV-2 mRNA vaccines. Within one to 21 days of either the first (n = 2) or second (n = 5) vaccine dose, these patients developed neurologic symptoms and MRI findings consistent with active CNS demyelination of the optic nerve, brain, and/or spinal cord. Symptoms included visual loss, dysmetria, gait instability, paresthesias, sphincter disturbance, and limb weakness. Age ranged from 24 to 64 (mean 39.1) years; five were woman (71.4%). The final diagnosis was exacerbation of known stable MS (n = 4, two were receiving disease-modifying therapy at the time of vaccination), new onset MS (n = 2), or new onset neuromyelitis optica (n = 1). All responded to corticosteroid (n = 7) or plasma exchange (n = 1) therapy, with five returning to baseline and two approaching baseline. Large prospective studies are required to further investigate any possible relationship between COVID-19 vaccines and acute CNS demyelination.

To examine the impact of lesion location on longitudinal myelin water fraction (MWF) changes in chronic multiple sclerosis (MS) lesions. Relative hypoxia, due to vascular watershed regions of the cerebrum, has been implicated in lesion development but impact on ongoing demyelination is unknown. Forty-eight patients with relapsing-remitting and secondary progressive MS had two MWF scans with fast acquisition, spiral trajectory, and T2prep (FAST-T2) sequence, at an interval of 2.0 (±.3) years. Lesion location was identified based upon cerebral lobe and relation to the ventricles. Change in MWF was assessed using a mixed effects model, controlling for lesion location and patient covariates. Average age was 42.3 (±12) years, mean disease duration was 9.7 (±9.1) years, and median Expanded Disability Status Score (EDSS) was 2.5 (±2.3). The majority of 512 chronic lesions was located in the frontal and parietal lobes (75.6%) and more often periventricular (44.7%). All occipital lesions were periventricular. The average lesion MWF decreased from baseline (.07 ± .03) to 2 years (.06 ±.03) P<.01. Lesions within the occipital lobe showed a significant reduction in MWF as compared to other lobes. Chronic lesions in the occipital lobe showed the greatest reduction in MWF. Neuroanatomical localization of lesions to the occipital horns of the lateral ventricles, a watershed region, may contribute to ongoing demyelination in this lesion type.

Background: The importance of supporting pregnancy-related decisions in multiple sclerosis (MS) patients has increasingly been recognized and hence the need for prospective data on pregnancy and pediatric outcomes in this patient population. Objective: To assess prospective growth and developmental outcomes of infants born to mothers with multiple sclerosis (IMS). Methods: PREG-MS is a prospective multicenter cohort study in New England, United States. We followed 65 women with MS and their infants with up to 12 months consistent pediatric follow-up. Pediatric, neurologic, and demographic information was obtained via structured telephone interviews and validated with medical records. Results: No differences in infant weights and lengths with World Health Organization (WHO) 50th percentile standards were observed (p > 0.05). However, larger head circumference (HC) measurements than WHO standards were reported in cohort infants (p < 0.05). There was no association between HC and markers of maternal MS activity, demographic, or social factors. No irreversible pediatric developmental abnormalities were observed. Conclusion: This first prospective study on pediatric anthropometry in IMS suggests a possible increase in HC compared to WHO standards without an increase in irreversible developmental abnormalities. The observations are exploratory and require confirmation with larger prospective studies in diverse groups of MS patients.

BackgroundSTRIVE is a multicenter, observational, open-label, single-arm study of natalizumab in anti–JC virus (JCV) seronegative patients with early relapsing-remitting multiple sclerosis (RRMS). The objective of this prespecified 2-year interim analysis was to determine the effectiveness of natalizumab in establishing and maintaining no evidence of disease activity (NEDA) in early RRMS.MethodsPatients aged 18–65 years had an RRMS diagnosis < 3 years prior to screening, an Expanded Disability Status Scale (EDSS) score ≤ 4.0, and anti-JCV antibody negative status. Magnetic resonance imaging was performed at baseline and yearly thereafter. Cumulative probabilities of 24-week–confirmed EDSS worsening and improvement were evaluated at 2 years. NEDA (no 24-week–confirmed EDSS worsening, no relapses, no gadolinium-enhancing lesions, and no new/newly enlarging T2-hyperintense lesions) was evaluated over 2 years. The Symbol Digit Modalities Test (SDMT) and Multiple Sclerosis Impact Score (MSIS-29) were assessed at baseline and 1 and 2 years. Statistical analysis used summary statistics and frequency distributions.ResultsThe study population (N = 222) had early RRMS, with mean (standard deviation [SD]) time since diagnosis of 1.6 (0.77) years and mean (SD) baseline EDSS score of 2.0 (1.13). NEDA was achieved in 105 of 187 patients (56.1%) during year 1 and 120 of 163 (73.6%) during year 2. Over 2 years, 76 of 171 patients (44.4%) attained overall NEDA. Probabilities of 24-week–confirmed EDSS worsening and improvement were 14.1% and 28.4%, respectively. After 2 years, patients exhibited significant improvements from baseline in SDMT (n = 158; mean [SD]: 4.3 [11.8]; p < 0.001) and MSIS-29 physical (n = 153; mean [SD]: − 3.9 [14.7]; p = 0.001), psychological (n = 152; mean [SD]: − 2.0 [7.9]; p < 0.001), and quality-of-life (n = 153; mean [SD]: − 6.0 [21.3]; p < 0.001) scores.ConclusionsThese results support natalizumab’s effectiveness over 2 years, during which nearly half of early RRMS patients achieved NEDA. During year 2, nearly 75% of patients exhibited NEDA. Over 2 years, patients continued to experience significant cognitive and quality-of-life benefits. These results are limited by the lack of a comparator group to determine the extent of a placebo effect.Trial registrationclinicaltrials.gov, NCT01485003, registered 5 December 2011.

To summarize current and emerging imaging techniques that can be used to assess neuroprotection and repair in multiple sclerosis (MS), and to provide a consensus opinion on the potential utility of each technique in clinical trial settings. Clinicians and scientists with expertise in the use of MRI in MS convened in Toronto, Canada, in November 2016 at a North American Imaging in Multiple Sclerosis (NAIMS) Cooperative workshop meeting. The discussion was compiled into a manuscript and circulated to all NAIMS members in attendance. Edits and feedback were incorporated until all authors were in agreement. A wide spectrum of imaging techniques and analysis methods in the context of specific study designs were discussed, with a focus on the utility and limitations of applying each technique to assess neuroprotection and repair. Techniques were discussed under specific themes, and included conventional imaging, magnetization transfer ratio, diffusion tensor imaging, susceptibility-weighted imaging, imaging cortical lesions, magnetic resonance spectroscopy, PET, advanced diffusion imaging, sodium imaging, multimodal techniques, imaging of special regions, statistical considerations, and study design. Imaging biomarkers of neuroprotection and repair are an unmet need in MS. There are a number of promising techniques with different strengths and limitations, and selection of a specific technique will depend on a number of factors, notably the question the trial seeks to answer. Ongoing collaborative efforts will enable further refinement and improved methods to image the effect of novel therapeutic agents that exert benefit in MS predominately through neuroprotective and reparative mechanisms.

Head-to-head clinical trials of teriflunomide (TFM) versus dimethyl fumarate (DMF) have not been conducted. To compare the real-world effectiveness of TFM versus DMF. Anonymized data were collected from patients with relapsing multiple sclerosis (MS) initiating treatment with teriflunomide (N=50) or DMF (N=50). On follow-up magnetic resonance imaging (MRI)compared with baseline, with TFM versus DMF treatment, the proportion of patients with new/enlarging T2 or gadolinium-enhancing lesions was 30.0 versus 40.0% (p =0.2752). However, median annualized percent whole brain volume change was -0.1 versus -0.5 (p =0.0212). There were no significant treatment differences on additional MRI and clinical end points and no unexpected safety signals. The effectiveness of teriflunomide was superior to DMF on whole brain atrophy and similar to DMF on other MRI/clinical end points.
