Abstract
BACKGROUND AND OBJECTIVES Although pediatric-onset multiple sclerosis (POMS) is characterized by a more rapid accumulation of CNS inflammation than adult-onset MS (AOMS), the therapeutic algorithms applied in POMS are usually based on AOMS therapeutic outcomes. To define a high-efficacy treatment (HET)-based strategy to treat POMS, we designed an observational retrospective study aimed at evaluating the efficacy and safety of natalizumab (NTZ) in naïve POMS and AOMS. METHODS Starting from 160 patients, we applied a 2:1 (adult:pediatric) matching on propensity scores and obtained 32 patients with NTZ-treated POMS and 64 with AOMS, estimated from a multivariable logistic regression model. All patients were clinically and radiologically followed up every 6 months for a mean period of 46.0 ± 26.9 months. RESULTS Following re-baseline at month 6, no difference (log-rank test: p = 0.924) in new and enlarging T2 white matter lesions, postcontrast T1 lesions, and relapse rate were observed between POMS and AOMS throughout the study. Progression independent of relapse activity (PIRA) was never observed in POMS, while 9 of 64 patients with AOMS (12.5%) had PIRA events during the follow-up (40.0 ± 25.9 months; log-rank p value 0.0156). JCV seroconversion rate during NTZ infusion did not differ between POMS and AOMS (log-rank test p = 0.3231). Finally, no serious adverse event was observed in both POMS and AOMS. DISCUSSION The favorable outcomes observed on clinical, especially in PIRA, and radiologic parameters strongly support the use of NTZ as a first-choice HET in POMS.

Abstract
Up to 10 years ago the most common approach to the treatment of pediatric MS (ped-MS) was to start with IFNB or GA (so-called first-line therapies or moderate-efficacy disease-modifying therapies [ME-DMTs]) and to switch to more aggressive treatments (or high-efficacy disease-modifying therapies [HE-DMTs]) in non-responder patients. The use of HE-DMTs as first choice was recommended in selected cases with an active, aggressive form of MS. Indications for the treatment of ped-MS were essentially derived from data of observational studies. Recently, results of three randomized clinical trials have been published as well as data from many observational studies evaluating the effect of new and more active DMTs, with clear evidence that HE-DMTs are more effective than ME-DMTs. Therefore, the paradigm of treatment for patients with MS onset before 18 years of age should be changed, offering treatment with HE-DMTs as first option, because of their superior effectiveness to prevent relapses and disease progression. HE-DMTs present an overall reassuring safety profile and obtain better adherence to treatment.

Abstract
The newly constituted National Multiple Sclerosis (MS) Society (NMSS)of the United Arab Emirates (UAE), set up a scientific committee to create a MS disease modifying treatment (DMT) guideline for UAE. The committee considered several unique features of the MS community in UAE including large number of expatriate population, wide variations in health insurance coverage, physician and patient preferences for DMT. The overall goal of the treatment guideline is to facilitate the most appropriate DMT to the widest number of patients. To this end it has adapted recommendations from various health systems and regulatory authorities into a pragmatic amalgamation of best practices from across the world. Importantly where data is unavailable or controversial, a common sense approach is taken rather than leave physicians and patients in limbo. The committee classifies MS into subcategories and suggests appropriate treatment choices. It recommends treatment of RIS and CIS with poor prognostic factors. It largely equates the efficacy and safety of DMT with similar mechanisms of action or drug classes e.g. ocrelizumab is similar to rituximab. It allows early switching of treatment for unambiguous disease activity and those with progression independent of relapses. Autologous hematopoietic stem cell transplantation can be offered to patients who fail one high efficacy DMT. Pragmatic guidance on switching and stopping DMT, DMT choices in pregnancy, lactation and pediatric MS have been included. It is expected that these guidelines will be updated periodically as new data becomes available.

Abstract
BACKGROUND Observational studies looking at clinical a++nd MRI outcomes of treatments in pediatric MS, could assess current treatment algorithms, and provide insights for designing future clinical trials. OBJECTIVE To describe baseline characteristics and clinical and MRI outcomes in MS patients initiating ocrelizumab and fingolimod under 18 years of age. METHODS MS patients seen at 12 centers of US Network of Pediatric MS were included in this study if they had clinical and MRI follow-up and started treatment with either ocrelizumab or fingolimod prior to the age of 18. RESULTS Eighty-seven patients initiating fingolimod and 52 initiating ocrelizumab met the inclusion criteria. Before starting fingolimod, mean annualized relapse rate was 0.43 (95 % CI: 0.29 - 0.65) and 78 % developed new T2 lesions while during treatment it was 0.12 (95 % CI: 0.08 - 1.9) and 47 % developed new T2 lesions. In the ocrelizumab group, the mean annualized relapse rate prior to initiation of treatment was 0.64 (95 % CI: 0.38-1.09) and a total of 83 % of patients developed new T2 lesions while during treatment it was 0.09 (95 % CI: 0.04-0.21) and none developed new T2 lesions. CONCLUSION This study highlights the importance of evaluating current treatment methods and provides insights about the agents in the ongoing phase III trial comparing fingolimod and ocrelizumab.

Abstract
BACKGROUND The double-blind TERIKIDS study demonstrated the efficacy and safety of teriflunomide. OBJECTIVE To evaluate the efficacy, safety, and tolerability of continuous teriflunomide treatment in the TERIKIDS open-label extension. METHODS In the double-blind period, children with relapsing MS were randomized to placebo or teriflunomide (14 mg adult-equivalent dose) for ⩽ 96 weeks. Participants received teriflunomide for ⩽ 192 weeks post-randomization in the open-label extension. RESULTS The mean age at screening was 14.6 years. For teriflunomide/teriflunomide versus placebo/teriflunomide, estimated clinical relapse risk was reduced by 38% (hazard ratio (HR) 0.62; 95% confidence interval (CI) 0.39-0.98; p = 0.11) and numbers of gadolinium-enhancing T1 and new/enlarging T2 lesions were reduced by 43% (relative risk (RR) 0.570; 95% CI 0.33-0.98; p = 0.043) and 49% (RR 0.511; 95% CI 0.34-0.76; p = 0.001), respectively, in the combined double-blind and open-label periods. There was a trend toward reduced risk of 24-week sustained disability progression for teriflunomide/teriflunomide versus placebo/teriflunomide (HR 0.47; 95% CI 0.23-0.96). During the open-label extension, incidences of safety-related discontinuations were 4.0% (teriflunomide/teriflunomide) and 13.5% (placebo/teriflunomide), including two children who developed pancreatitis in the teriflunomide/teriflunomide group. CONCLUSION Teriflunomide reduced the long-term risk of focal inflammatory activity, with generally manageable tolerability and no new safety signals. Further evidence would strengthen clinical efficacy findings.ClinicalTrials.gov: NCT02201108.

Abstract
BACKGROUND Multiple sclerosis (MS) is a central nervous system (CNS) demyelinating autoimmune disease with increasing global prevalence. It predominantly affects females, especially those of European descent. The interplay between environmental factors and genetic predisposition plays a crucial role in MS etiopathogenesis. METHODS We searched recent relevant literature on reputable databases, which include, PubMed, Embase, Web of Science, Scopus, and ScienceDirect using the following keywords: multiple sclerosis, pathogenesis, autoimmunity, demyelination, therapy, and immunotherapy. RESULTS Various animal models have been employed to investigate the MS etiopathogenesis and therapeutics. Autoreactive T cells within the CNS recruit myeloid cells through chemokine expression, leading to the secretion of inflammatory cytokines driving the MS pathogenesis, resulting in demyelination, gliosis, and axonal loss. Key players include T cell lymphocytes (CD4+ and CD8+), B cells, and neutrophils. Signaling dysregulation in inflammatory pathways and the immunogenetic basis of MS are essential considerations for any successful therapy to MS. Data indicates that B cells and neutrophils also have significant roles in MS, despite the common belief that T cells are essential. High neutrophil-to-lymphocyte ratios correlate with MS severity, indicating their contribution to disease progression. Dysregulated signaling pathways further exacerbate MS progression. CONCLUSION MS remains incurable, but disease-modifying therapies, monoclonal antibodies, and immunomodulatory drugs offer hope for patients. Research on the immunogenetics and immunoregulatory functions of gut microbiota is continuing to provide light on possible treatment avenues. Understanding the complex interplay between genetic predisposition, environmental factors, and immune dysregulation is critical for developing effective treatments for MS.

Abstract
Background Teriflunomide is a once-daily oral disease-modifying therapy (DMT) for the treatment of relapsing-remitting multiple sclerosis (RRMS). Only limited information is available about its real-world use and changes over time. Objectives To collect real-world data on teriflunomide use in clinical routine (and comparison to the previously conducted study TAURUS-MS). Design National, open, non-interventional, prospective, multicenter study. Methods TAURUS-MS II was conducted at 220 German sites between July 2017 and March 2022, including RRMS patients treated with teriflunomide. Data on patient demographics, MS history, previous treatment, therapy satisfaction, and safety were collected. Results In total, 752 patients were included (65% female) with a mean age (±standard deviation) of 43 ± 11 years. Sixty-six percent had DMT before, and 46% had discontinued their last pretreatment ≤6 months prior to study entry. Among the latter, previous DMTs were interferon (21%), glatiramer acetate (11%), and dimethyl fumarate (9%), and reasons for discontinuation were adverse events (AEs; 55%) and insufficient efficacy (16%). Over 24 months, the mean treatment Satisfaction Questionnaire for Medication scores improved by 6 ± 29 points on effectiveness, 8 ± 20 on convenience, and 12 ± 25 on global satisfaction. The mean number of MS relapses decreased from 0.81 ± 0.81 in the 24 months prior to 0.27 ± 0.57 within 24 months after study entry. Non-serious AEs occurred in 423 patients (56%) and serious AEs in 49 patients (7%). Most reported AEs were alanine aminotransferase increase (11%), hypertension (8%), and alopecia (7%). Compared to TAURUS-MS, patients in TAURUS-MS II were younger, had a higher employment rate, and a higher share of treatment-naïve patients. Conclusion Mean number of relapses was significantly reduced. Patient satisfaction was significantly improved compared to previous DMT. Tolerability was comparable to previous trials.

Abstract
BACKGROUND AND PURPOSE Rituximab (RTX) is frequently used off-label in multiple sclerosis. However, studies on the risk-benefit profile of RTX in pediatric-onset multiple sclerosis are scarce. METHODS In this multicenter retrospective cohort study, patients with pediatric-onset multiple sclerosis from Sweden, Austria and Germany, who received RTX treatment were identified by chart review. Annualized relapse rates, Expanded Disability Status Scale scores and magnetic resonance imaging parameters (new T2 lesions and contrast-enhancing lesions) were assessed before and during RTX treatment. The proportion of patients who remained free from clinical and disease activity (NEDA-3) during RTX treatment was calculated. Side effects such as infusion-related reactions, infections and laboratory abnormalities were assessed. RESULTS Sixty-one patients received RTX during a median (interquartile range) follow-up period of 20.9 (35.6) months. The annualized relapse rate decreased from 0.6 (95% confidence interval [CI] 0.38-0.92) to 0.03 (95% CI 0.02-0.14). The annual rate of new T2 lesions decreased from 1.25 (95% CI 0.70-2.48) to 0.08 (95% CI 0.03-0.25) and annual rates of new contrast-enhancing lesions decreased from 0.86 (95% CI 0.30-3.96) to 0. Overall, 70% of patients displayed no evidence of disease activity (NEDA-3). Adverse events were observed in 67% of patients. Six patients discontinued treatment due to ongoing disease activity or adverse events. CONCLUSION Our study provides class IV evidence that RTX reduces clinical and radiological activity in pediatric-onset multiple sclerosis.

Disease-modifying therapies in managing disability worsening in paediatric-onset multiple sclerosis: a longitudinal analysis of global and national registries. THE LANCET. CHILD & ADOLESCENT HEALTH 2024; 8:348-357. [PMID: 38547883 DOI: 10.1016/s2352-4642(24)00047-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 02/13/2024] [Accepted: 02/14/2024] [Indexed: 04/14/2024]
Abstract
BACKGROUND High-efficacy disease-modifying therapies have been proven to slow disability accrual in adults with relapsing-remitting multiple sclerosis. However, their impact on disability worsening in paediatric-onset multiple sclerosis, particularly during the early phases, is not well understood. We evaluated how high-efficacy therapies influence transitions across five disability states, ranging from minimal disability to gait impairment and secondary progressive multiple sclerosis, in people with paediatric-onset multiple sclerosis. METHODS Longitudinal data were obtained from the international MSBase registry, containing data from people with multiple sclerosis from 151 centres across 41 countries, and the Italian Multiple Sclerosis and Related Disorders Register, containing data from people with multiple sclerosis from 178 Italian multiple sclerosis centres. People younger than 18 years at the onset of multiple sclerosis symptoms were included, provided they had a confirmed diagnosis of relapsing-remitting multiple sclerosis and at least four Expanded Disability Status Scale (EDSS) scores recorded within 12-month intervals. The primary outcome was the time to change in disability state: minimal disability (EDSS scores 0, 1·0, and 1·5), mild disability (EDSS scores 2·0 and 2·5), moderate disability (EDSS scores 3·0 and 3·5), gait impairment (EDSS scores ≥4·0), and clinician diagnosed secondary progressive multiple sclerosis. A multi-state model was constructed to simulate the natural course of multiple sclerosis, modelling the probabilities of both disability worsening and improvement simultaneously. The impact of high-efficacy disease-modifying therapies (alemtuzumab, cladribine, daclizumab, fingolimod, mitoxantrone, natalizumab, ocrelizumab, rituximab, or autologous haematopoietic stem cell transplantation) and low-efficacy disease-modifying therapies (dimethyl fumarate, glatiramer acetate, interferon beta, or teriflunomide), compared with no treatment, on the course of disability was assessed. Apart from recruitment, individuals with lived experience of multiple sclerosis were not involved in the design and conduct of this study. FINDINGS A total of 5224 people (3686 [70·6%] female and 1538 [29·4%] male) with mean age at onset of multiple sclerosis 15·24 years (SD 2·52) were included. High-efficacy therapies reduced the hazard of disability worsening across the disability states. The largest reduction (hazard ratio 0·41 [95% CI 0·31-0·53]) was observed in participants who were treated with high-efficacy therapies while in the minimal disability state, compared with those remained untreated. The benefit of high-efficacy therapies declined with increasing disability. Young people with minimal disability who received low-efficacy therapy also experienced a reduced hazard (hazard ratio 0·65 [95% CI 0·54-0·77]) of transitioning to mild disability, in contrast to those who remained untreated. INTERPRETATION Treatment of paediatric-onset relapsing-remitting multiple sclerosis with high-efficacy therapy substantially reduces the risk of reaching key disability milestones. This reduction in risk is most pronounced among young people with minimal or mild disability when treatment began. Children with relapsing-remitting multiple sclerosis should be treated early with high-efficacy therapy, before developing significant neurological impairments, to better preserve their neurological capacity.

Abstract
Multiple sclerosis (MS) was defined as a rare disease in China due to its low prevalence. For a long time, interferon β was the only approved disease-modifying therapy (DMT). Since the first oral DMT was approved in 2018, DMT approval accelerated, and seven DMTs were approved within 5 years. With an increasing number of DMTs being prescribed in clinical practice, it is necessary to discuss the standardized MS treatment algorithms depending on the disease activity and DMT availability. In this review paper, more than 20 Chinese experts in MS have reviewed the therapeutic progress of MS in China and worldwide and discussed algorithms for treating relapsing MS (RMS) based on the available DMTs in China, providing insights for establishing the standardized RMS treatment algorithms in this country.

Abstract
Multiple sclerosis (MS) is a chronic, progressive, inflammatory disorder of the central nervous system. Relapsing-remitting MS (RRMS), the most common form of the disease, is characterized by transient neurological dysfunction with concurrent accumulation of disability. Over the past three decades, disease-modifying therapies (DMTs) capable of reducing the frequency of relapses and slowing disability worsening have been studied and approved for use in patients with RRMS. The first DMTs were interferon-betas (IFN-βs), which were approved in the 1990s. Among them was IFN-β-1a for subcutaneous (sc) injection (Rebif®), which was approved for the treatment of MS in Europe and Canada in 1998 and in the USA in 2002. Twenty years of clinical data and experience have supported the efficacy and safety of IFN-β-1a sc in the treatment of RRMS, including pivotal trials, real-world data, and extension studies lasting up to 15 years past initial treatment. Today, IFN-β-1a sc remains an important therapeutic option in clinical use, especially around pregnancy planning and lactation, and may also be considered for aging patients, in which MS activity declines and long-term immunosuppression associated with some alternative therapies is a concern. In addition, IFN-β-1a sc is used as a comparator in many clinical studies and provides a framework for research into the mechanisms by which MS begins and progresses.

Abstract
With evolving diagnostic criteria and the advent of new oral and parenteral therapies for Multiple Sclerosis (MS), most current diagnostic and treatment algorithms need revision and updating. The diagnosis of MS relies on incorporating clinical and paraclinical findings to prove dissemination in space and time and exclude alternative diseases that can explain the findings at hand. The differential diagnostic workup should be guided by clinical and laboratory red flags to avoid unnecessary tests. Appropriate selection of MS therapies is critical to maximize patient benefit. The current guidelines review the current diagnostic criteria for MS and the scientific evidence supporting treatment of acute relapses, radiologically isolated syndrome, clinically isolated syndrome, relapsing remitting MS, progressive MS, pediatric cases and pregnant women. The purpose of these guidelines is to provide practical recommendations and algorithms for the diagnosis and treatment of MS based on current scientific evidence and clinical experience.

Abstract
Importance Moderately effective therapies (METs) have been the main treatment in pediatric-onset multiple sclerosis (POMS) for years. Despite the expanding use of highly effective therapies (HETs), treatment strategies for POMS still lack consensus. Objective To assess the real-world association of HET as an index treatment compared with MET with disease activity. Design, Setting, and Participants This was a retrospective cohort study conducted from January 1, 2010, to December 8, 2022, until the last recorded visit. The median follow-up was 5.8 years. A total of 36 French MS centers participated in the Observatoire Français de la Sclérose en Plaques (OFSEP) cohort. Of the total participants in OFSEP, only treatment-naive children with relapsing-remitting POMS who received a first HET or MET before adulthood and at least 1 follow-up clinical visit were included in the study. All eligible participants were included in the study, and none declined to participate. Exposure HET or MET at treatment initiation. Main Outcomes and Measures The primary outcome was the time to first relapse after treatment. Secondary outcomes were annualized relapse rate (ARR), magnetic resonance imaging (MRI) activity, time to Expanded Disability Status Scale (EDSS) progression, tertiary education attainment, and treatment safety/tolerability. An adapted statistical method was used to model the logarithm of event rate by penalized splines of time, allowing adjustment for effects of covariates that is sensitive to nonlinearity and interactions. Results Of the 3841 children (5.2% of 74 367 total participants in OFSEP), 530 patients (mean [SD] age, 16.0 [1.8] years; 364 female [68.7%]) were included in the study. In study patients, both treatment strategies were associated with a reduced risk of first relapse within the first 2 years. HET dampened disease activity with a 54% reduction in first relapse risk (adjusted hazard ratio [HR], 0.46; 95% CI, 0.31-0.67; P < .001) sustained over 5 years, confirmed on MRI activity (adjusted odds ratio [OR], 0.34; 95% CI, 0.18-0.66; P = .001), and with a better tolerability pattern than MET. The risk of discontinuation at 2 years was 6 times higher with MET (HR, 5.97; 95% CI, 2.92-12.20). The primary reasons for treatment discontinuation were lack of efficacy and intolerance. Index treatment was not associated with EDSS progression or tertiary education attainment (adjusted OR, 0.51; 95% CI, 0.24-1.10; P = .09). Conclusions and Relevance Results of this cohort study suggest that compared with MET, initial HET in POMS was associated with a reduction in the risk of first relapse with an optimal outcome within the first 2 years and was associated with a lower rate of treatment switching and a better midterm tolerance in children. These findings suggest prioritizing initial HET in POMS, although long-term safety studies are needed.

Abstract
Chronologic aging is associated with multiple pathologic and immunologic changes that impact the clinical course of multiple sclerosis (MS). Clinical phenotypes evolve across the lifespan, from a highly inflammatory course in the very young to a predominantly neurodegenerative phenotype in older patients. Thus, unique clinical considerations arise for the diagnosis and management of the two age extremes of pediatric and geriatric MS populations. This review covers epidemiology, diagnosis, and treatment strategies for these populations with nuanced discussions on therapeutic approaches to effectively care for patients living with MS at critical transition points during their lifespan.

Abstract
Multiple sclerosis remains one of the most common causes of neurological disability in the young adult population (aged 18-40 years). Novel pathophysiological findings underline the importance of the interaction between genetics and environment. Improvements in diagnostic criteria, harmonised guidelines for MRI, and globalised treatment recommendations have led to more accurate diagnosis and an earlier start of effective immunomodulatory treatment than previously. Understanding and capturing the long prodromal multiple sclerosis period would further improve diagnostic abilities and thus treatment initiation, eventually improving long-term disease outcomes. The large portfolio of currently available medications paved the way for personalised therapeutic strategies that will balance safety and effectiveness. Incorporation of cognitive interventions, lifestyle recommendations, and management of non-neurological comorbidities could further improve quality of life and outcomes. Future challenges include the development of medications that successfully target the neurodegenerative aspect of the disease and creation of sensitive imaging and fluid biomarkers that can effectively predict and monitor disease changes.

Abstract
Background Paediatric-onset multiple sclerosis (POMS) therapeutic approach derives from of adult-onset multiple sclerosis (AOMS) tailored algorithms. Objectives To evaluate in a common clinical scenario the efficacy and safety of alemtuzumab (ALZ) in POMS and AOMS. Methods All patients switching from natalizumab (NTZ) to ALZ for safety concerns (high anti-John Cunningham Virus Antibody Index value, anti-JCV Index) were enrolled in this single-centre, retrospective, case-control open-label study. Results Ten POMS and 27 AOMS were followed up for 51.3 months. After month 12, we found a lower risk of clinical or radiological relapses among AOMS patients and among patients with older age at ALZ (both p < 0.05). Survival analysis revealed an increased risk of relapse in POMS compared with AOMS (logrank p = 0.00498) and patients starting ALZ before age 22.75 years than the elder ones (logrank p = 0.0018). Survival analysis did not disclose any difference between AOMS and POMS (logrank p = 0.27) in terms of progression independent of any relapse activity (PIRA). In addition, no evidence of relapse-associated worsening was observed. Autoimmune events were reported by 5 AOMS and no POMS (29.4% versus 0.0%, p = 0.057), and survival analysis was not significant (logrank p = 0.0786). Conclusion ALZ seems more effective in AOMS than in POMS following NTZ. These findings underrate ALZ effectiveness when shifting from NTZ in POMS.

Abstract
INTRODUCTION Different disease-modifying therapies (DMTs) have been developed to slow down the progression of pediatric multiple sclerosis (MS). Teriflunomide is one such DMT that has recently been approved for use in pediatric MS in the European Union. AREAS COVERED The article provides an introduction to the mechanism of action of teriflunomide, reviews the clinical trials conducted on the safety and efficacy of the drug, and the optimal dosing and monitoring strategies. EXPERT OPINION Teriflunomide is an oral medication that has shown promise in improving outcomes for pediatric MS patients, including reduced relapse rates and improved quality of life. However, more research is needed to determine its long-term safety in pediatric patients. As MS often presents with an aggressive course in children, the choice of disease-modifying treatment should be carefully evaluated, with a preference for second-line therapy. Despite the potential benefits of teriflunomide, changes in clinical practice may be hindered by factors such as cost and physician familiarity with alternative treatments. Longer-term studies and biomarker identification are areas for improvement, but the future of research in this area holds promise for the continued development and refinement of disease-modifying therapies and more personalized, targeted treatments for pediatric MS patients.

Abstract
AIM To compare the efficacy and safety of newer and/or second-line disease-modifying treatments (DMTs) with interferon beta-1a. METHOD This observational retrospective study included patients younger than 18 years old in the French KIDBIOSEP cohort who had a diagnosis of relapsing multiple sclerosis between 2008 and 2019 and received at least one DMT. Primary outcome was the annualized relapse rate (ARR). Secondary outcomes were the risk of new T2 or gadolinium-enhanced lesions on brain MRI. RESULTS Among 78 patients enrolled, 50 were exposed to interferon and 76 to newer DMTs. Mean ARR went from 1.65 during pre-treatment period to 0.45 with interferon (p < 0.001). Newer DMTs reduced ARR compared to interferon: fingolimod 0.27 (p = 0.013), teriflunomide 0.25 (p = 0.225), dimethyl-fumarate 0.14 (p = 0.045), natalizumab 0.03 (p = 0.007). Risk of new lesions on MRI was reduced with interferon compared to pre-treatment period; it decreased even more with newer DMTs for T2 lesions. Regarding risk of new gadolinium-enhanced lesions, the added value of new treatments compared to interferon was less obvious, except for natalizumab (p = 0.031). CONCLUSION In this real-world setting, newer DMTs showed better efficacy than interferon beta-1a on ARR and risk of new T2 lesions, with a good safety profile. Natalizumab tend to emerge as the most effective treatment.

Abstract
The current diagnostic criteria for pediatric onset multiple sclerosis (POMS) are summarized, as well as the evidence for performance of the most recent iteration of McDonald criteria in the pediatric population. Next, the varied roles of MRI in POMS are reviewed, including diagnostic considerations and research-based utilization. The primary role of bloodwork and cerebrospinal fluid studies in the diagnosis of POMS is to rule out disease mimics. Prognostically, POMS portends a more inflammatory course with higher relapse rate and disability reached at younger ages compared with AOMS counterparts. As such, there is an emerging trend toward the earlier use of highly efficacious disease modifying therapies to target prompt immunomodulatory disease control. Current POMS disease modifying therapies (DMTs) and active clinical POMS trials are detailed.

Abstract
Multiple sclerosis (MS) primarily affects adult females. However, in the last decades, rising incidence and prevalence have been observed for demographic extremes, such as pediatric-onset MS (POMS; occurring before 18 years of age) and late-onset MS (corresponding to an onset above 50 years). These categories show peculiar clinical-pathogenetic characteristics, aging processes and disease courses, therapeutic options, and unmet needs. Nonetheless, several open questions are still pending. POMS patients display an important contribution of multiple genetic and environmental factors such as EBV, while in LOMS, hormonal changes and pollution may represent disease triggers. In both categories, immunosenescence emerges as a pathogenic driver of the disease, particularly for LOMS. In both populations, patient and caregiver engagement are essential from the diagnosis communication to early treatment of disease-modifying therapy (DMTs), which in the elderly population appears more complex and less proven in terms of efficacy and safety. Digital technologies (e.g., exergames and e-training) have recently emerged with promising results, particularly in treating and following motor and cognitive deficits. However, this offer seems more feasible for POMS, being LOMS less familiar with digital technology. In this narrative review, we discuss how the aging process influences the pathogenesis, disease course, and therapeutic options of both POMS and LOMS. Finally, we evaluate the impact of new digital communication tools, which greatly interest the current and future management of POMS and LOMS patients.

Abstract
BACKGROUND The phase 3 TERIKIDS study demonstrated efficacy and manageable safety for teriflunomide versus placebo in children with relapsing multiple sclerosis (RMS). OBJECTIVE Evaluate plasma neurofilament light chain (pNfL) concentrations in TERIKIDS. METHODS Patients received placebo or teriflunomide (14 mg adult equivalent) for up to 96 weeks in the double-blind (DB) period. In the open-label extension (OLE), all patients received teriflunomide until up to 192 weeks after randomization. pNfL was measured using single-molecule array assay (Simoa® NF-light™). RESULTS Baseline mean age was 14.5 years; 69.4% were female. Baseline geometric least square mean pNfL levels were similar for teriflunomide (n = 78) and placebo (n = 33) patients (19.83 vs 18.30 pg/mL). Over the combined DB and OLE periods, pNfL values were lower for teriflunomide versus placebo (analysis of variance p < 0.01; Week 192: 10.61 vs 17.32 pg/mL). Observed between-group pNfL differences were attenuated upon adjustment for gadolinium (Gd)-enhancing or new/enlarged T2 lesion counts at DB Week 24. Higher baseline pNfL levels were associated with shorter time since first MS symptom onset, higher baseline Gd-enhancing lesion counts and T2 lesion volume, and increased hazard of high magnetic resonance imaging activity or clinical relapse during the DB period. CONCLUSION Teriflunomide treatment was associated with significantly reduced pNfL levels in children with RMS. CLINICALTRIALS.GOV IDENTIFIER NCT02201108.

Abstract
Alzheimer's disease (AD) and ischemic stroke (IS) are common neurological disorders, and the comorbidity of these two brain diseases is often seen. Although AD and IS were regarded as two distinct disease entities, in terms of different etiologies and clinical presentation, recent genome-wide association studies (GWASs) revealed that there were common risk genes between AD and IS, indicating common molecular pathways and their common pathophysiology. In this review, we summarize AD and IS risk single nucleotide polymorphisms (SNPs) and their representative genes from the GWAS Catalog database, and find thirteen common risk genes, but no common risk SNPs. Furthermore, the common molecular pathways associated with these risk gene products are summarized from the GeneCards database and clustered into inflammation and immunity, G protein-coupled receptor, and signal transduction. At least seven of these thirteen genes can be regulated by 23 microRNAs identified from the TargetScan database. Taken together, the imbalance of these molecular pathways may give rise to these two common brain disorders. This review sheds light on the pathogenesis of comorbidity of AD and IS, and provides molecular targets for disease prevention, manipulation, and brain health maintenance.

Abstract
OBJECTIVES Long-term immunomodulatory therapy of pediatric onset-multiple sclerosis (POMS) is based mainly on published case series and internationally agreed guidelines. Relevant studies in the Greek population are absent from the literature. The purpose of this study is to present data on the efficacy and safety of the 1st line immunomodulatory drugs in the treatment of POMS patients. MATERIALS AND METHODS The present study included 27 patients meeting the IPMSSG criteria for POMS and who are monitored at the outpatient clinic of the Multiple Sclerosis and Demyelinating Diseases Unit (MSDDU), of the 1st Neurological Department, University Hospital of Aeginition. All patients received 1st line immunomodulatory drugs as initial therapy. Clinical, laboratory, and imaging parameters of the disease were recorded before and after treatment. RESULTS Post-treatment, a significant reduction of the relapse number (mean ± SD: 2.0 ± 1.0 vs 1.2 ± 1.6, p = 0.002), EDSS progression (mean ± SD: 1.5 ± 0.8 vs 0.9 ± 0.7, p = 0.005) and ARR (mean ± SD: 1.5 ± 0.7 vs 0.4 ± 0.5, p = 0.0001) was observed, while no changes were observed in the EDSS score, (mean ± SD: 1.8 ± 0.6 vs 1.9. 0.6, p = 0.60). Advanced age at treatment initiation increased the risk for drug discontinuation before 24 months of therapy (HR = 0.6, 95% CI (0.35-0.99), p = 0.04). CONCLUSIONS Most pediatric patients are forced to switch to either more efficacious 1st line or 2nd line drugs. Additionally, our study suggests that older age at the time of the 1st line treatment initiation, contributes to earlier drug discontinuation.

Abstract
Multiple sclerosis (MS), particularly relapsing MS (RMS), has become a treatable disease in recent decades, and immunotherapies are now able to influence long-term disease course. A wide range of disease-modifying drugs are available, which makes the choice of therapy in individual cases considerably more complex. Due to specific regulatory aspects (partly diverging approvals by Swissmedic compared to the European Medicines Agency (EMA), and an independent evaluation process for the Federal Office of Public Health (FOPH) specialities list (SL)), we issued a consensus recommendation regarding specific aspects of immunotherapy for MS in Switzerland in 2019. Here, we present revised recommendations with an update on newly approved drugs and new safety aspects, also in reference to the risk of COVID-19 infection and vaccination.

Abstract
Introduction: Pediatric-onset multiple sclerosis (POMS) is characterized by high inflammatory disease activity. Our aim was to describe the treatment sequencing and report the impact highly effective disease-modifying treatment (HET) had on disease activity. Materials and Methods: Five consecutive patients with POMS were administered HET following lower efficacy drug or as initial therapy. Data on treatment sequencing, relapses and MRIs were collected during the follow-up. Results: Our patients had an average age of 13.8 years (range 9–17) at diagnosis and 13.4 years (range 9–16) at disease onset, and 2/5 (40%) POMS were female. The pre-treatment average annualized relapse rate was 1.6 (range 0.8–2.8), and the average follow-up length was 5 years (range 3–7). A total of 2/5 (40%) patients were stable on HET at initial therapy, and 3/5 (60%) required an escalation to more aggressive treatment, even if two of them had been put on HET as initial treatment. Four out of five patients (80%) had No Evidence of Disease Activity-3 status (NEDA-3) at an average follow-up of 3 years (range 2–5). Conclusion: It has been observed that in a recent time period all the cases had prompt diagnosis, early HET or escalation to HET with a good outcome in 80% of the cases.

Abstract
BACKGROUND Disease modifying treatments (DMTs) for multiple sclerosis include injectable drugs (iDMTs) like interferons (IFNs) or glatiramer acetate (GA), and newer agents (nDMTs) in oral and intravenous forms. nDMTs are usually applied in escalation and less frequently as initial treatment in pediatric-onset (POMS). OBJECTIVE We intended to evaluate the effect of nDMTs in comparison with iDMTs by retrospective examination of our patients with POMS. METHOD Clinical records of POMS cases who received nDMTs either as escalation or initial treatment and who had at least 12 months' follow-up in our clinic were examined in two groups: patients who were started on iDMTs and later switched to nDMTs (Group A), and those who received nDMTs from the beginning (Group B). Presenting symptoms, annualized relapsing rate (ARR), recent Expanded Disability Status Scale (EDSS), lesion load and presence of contrast enhancing (CE) lesions on magnetic resonance imaging (MRI) were compared. RESULTS Total 43 patients were included: 33 in Group A and 10 in Group B. Age at onset, female/male ratio, duration since disease onset and duration under nDMT were similar in both groups. Initial involvement was predominantly brainstem and cerebellar in Group A and sensorial, brainstem/cerebellar, and optic nerve in Group B. The most frequently used nDMT was fingolimod in Group A (n = 17, 51.5%) and teriflunomide (n = 6, 60%) in Group B. Median ARR before any treatment was 2 in Group A and 1.5 in Group B (p > 0.05); it decreased to median 1 under iDMTs in Group A and to 0 under nDMTs. Mean follow-up was 6.7 ± 5 years (1-19, median 6 years) in Group A and 3.9 ± 3.7 years (range 1-12, median 2 years) in Group B. At the latest follow-up median EDSS scores were 1 in Group A and 0 in Group B. ARR had increased and lesion load on MRI went up progressively in both groups during follow-up. However, the rate of patients with CE lesions diminished in Group B. CONCLUSION This single-center study of POMS shows the ARR decreases under any treatment, more markedly under nDMTs, and nDMTs reduce the rate of patients with CE lesions on MRI without a clear effect on lesion load. The ARR tends to increase after the first 2 years of both iDMT and nDMT, suggesting a re-evaluation at that time. The ARR decreases shorty after treatment is changed from an iDMT to a nDMT.

Abstract
Calculating the crude or adjusted annualized relapse rate (ARR) and its confidence interval (CI) is often required in clinical studies to evaluate chronic relapsing diseases, such as multiple sclerosis and neuromyelitis optica spectrum disorders. However, accurately calculating ARR and estimating the 95% CI requires careful application of statistical approaches and basic familiarity with the exponential family of distributions. When the relapse rate can be regarded as constant over time or by individuals, the crude ARR can be calculated using the person-years method, which divides the number of all observed relapses among all participants by the total follow-up period of the study cohort. If the number of relapses can be modeled by the Poisson distribution, the 95% CI of ARR can be obtained by finding the 2.5% upper and lower critical values of the parameter λ as the mean. Basic familiarity with F-statistics is also required when comparing the ARR between two disease groups. It is necessary to distinguish the observed relapse rate ratio (RR) between two sample groups (sample RR) from the unobserved RR between their originating populations (population RR). The ratio of population RR to sample RR roughly follows the F distribution, with degrees of freedom obtained by doubling the number of observed relapses in the two sample groups. Based on this, a 95% CI of the population RR can be estimated. When the count data of the response variable is overdispersed, the negative binomial distribution would be a better fit than the Poisson. Adjusted ARR and the 95% CI can be obtained by using the generalized linear regression models after selecting appropriate error structures (e.g., Poisson, negative binomial, zero-inflated Poisson, and zero-inflated negative binomial) according to the overdispersion and zero-inflation in the response variable.

Abstract
Multiple sclerosis (MS) is an autoimmune disease affecting the central nervous system that causes significant disability and healthcare burden. The treatment of MS has evolved over the past three decades with development of new, high efficacy disease modifying therapies targeting various mechanisms including immune modulation, immune cell suppression or depletion and enhanced immune cell sequestration. Emerging therapies include CNS-penetrant Bruton's tyrosine kinase inhibitors and autologous hematopoietic stem cell transplantation as well as therapies aimed at remyelination or neuroprotection. Therapy development for progressive MS has been more challenging with limited efficacy of current approved agents for inactive disease and older patients with MS. The aim of this review is to provide a broad overview of the current therapeutic landscape for MS.

Abstract
PURPOSE OF REVIEW Although substantial progress has been made in understanding the natural history of multiple sclerosis (MS) and the development of new therapies, many questions concerning disease behavior and therapeutics remain to be answered. Data generated from real-world observational studies, based on large MS registries and databases and analyzed with advanced statistical methods, are offering the scientific community answers to some of these questions that are otherwise difficult or impossible to address. This review focuses on observational studies published in the last 2 years designed to compare the effectiveness of escalation vs. induction treatment strategies, to assess the effectiveness of treatment in pediatric-onset and late-onset MS, and to identify the clinical phenotype of secondary progressive (SP)MS. RECENT FINDINGS The main findings originating from real-world studies suggest that MS patients who will qualify for high-efficacy disease-modifying therapies (DMTs) should be offered these as early as possible to prevent irreversible accumulation of neurological disability. Especially pediatric patients derive substantial benefits from early treatment. In patients with late-onset MS, sustained exposure to DMTs may result in more favorable outcomes. Data-driven definitions are more accurate in defining transition to SPMS than diagnosis based solely on neurologists' judgment. SUMMARY Patients, physicians, industry, and policy-makers have all benefited from real-world evidence based on registry data, in answering questions of diagnostics, choice of treatment, and timing of treatment decisions.

Abstract
Background: To support innovative trial designs in a regulatory setting for pediatric-onset multiple sclerosis (MS), the study aimed to perform a systematic literature review and meta-analysis of relapse rates with interferon β (IFN β), fingolimod, and natalizumab and thereby demonstrate potential benefits of Bayesian and non-inferiority designs in this population. Methods: We conducted a literature search in MEDLINE and EMBASE from inception until 17 June 2020 of all studies reporting annualized relapse rates (ARR) in IFN β-, fingolimod-, or natalizumab-treated patients with pediatric-onset relapsing–remitting MS. These interventions were chosen because the literature was mainly available for these treatments, and they are currently used for the treatment of pediatric MS. Two researchers independently extracted data and assessed study quality using the Cochrane Effective Practice and Organization of Care – Quality Assessment Tool. The meta-analysis estimates were obtained by Bayesian random effects model. Data were summarized as ARR point estimates and 95% credible intervals. Results: We found 19 articles, including 2 randomized controlled trials. The baseline ARR reported was between 1.4 and 3.7. The meta-analysis-based ARR was significantly higher in IFN β-treated patients (0.69, 95% credible interval: 0.51–0.91) versus fingolimod (0.11, 0.04–0.27) and natalizumab (0.17, 0.09–0.31). Based on the meta-analysis results, an appropriate non-inferiority margin versus fingolimod could be in the range of 2.29–2.67 and for natalizumab 1.72–2.29 on the ARR ratio scale. A Bayesian design, which uses historical information for a fingolimod or natalizumab control arm, could reduce the sample size of a new trial by 18 or 14 patients, respectively. Conclusion: This meta-analysis provides evidence that relapse rates are considerably higher with IFNs versus fingolimod or natalizumab. The results support the use of innovative Bayesian or non-inferiority designs to avoid exposing patients to less effective comparators in trials and bringing new medications to patients more efficiently.

Abstract
Pediatric-onset multiple sclerosis (POMS) is a rare neuroinflammatory and neurodegenerative disease that has a significant impact on long-term physical and cognitive patient outcomes. A small percentage of multiple sclerosis (MS) diagnoses occur before the age of 18 years. Before treatment initiation, a careful differential diagnosis and exclusion of other similar acquired demyelinating syndromes such as anti-aquaporin-4-associated neuromyelitis optica spectrum disorder (AQP4-NMOSD) and myelin oligodendrocyte glycoprotein antibody spectrum disorder (MOGSD) is warranted. The recent 2017 changes to the McDonald criteria can successfully predict up to 71% of MS diagnoses and have good specificity of 95% and sensitivity of 71%. Additional measures such as the presence of T1-weighted hypointense lesions and/or contrast-enhancing lesions significantly increase the accuracy of diagnosis. In adults, early use of disease-modifying therapies (DMTs) is instrumental to a better long-term prognosis, including lower rates of relapse and disability worsening, and numerous FDA-approved therapies for adult-onset MS are available. However, unlike their adult counterparts, the development, testing, and regulatory approval of POMS treatments have been significantly slower and hindered by logistic and/or ethical considerations. Currently, only two MS DMTs (fingolimod and teriflunomide) have been tested in large phase III trials and approved by regulatory agencies for use in POMS. First-line therapies not approved by the FDA for use in children (interferon-β and glatiramer acetate) are also commonly used and result in a significant reduction in inflammatory activity when compared with non-treated POMS patients. An increasing number of POMS patients are now treated with moderate efficacy therapies such as dimethyl fumarate and high-efficacy therapies such as natalizumab, anti-CD20 monoclonal antibodies, anti-CD52 monoclonal antibodies, and/or autologous hematopoietic stem cell transplantation. These high-efficacy DMTs generally provide additional reduction in inflammatory activity when compared with the first-line medications (up to 62% of relapse-rate reduction). Therefore, a number of phase II and III trials are currently investigating their efficacy and safety in POMS patients. In this review, we discuss potential changes in the regulatory approval process for POMS patients that are recommended for DMTs already approved for the adult MS population, including smaller sample size for pharmacokinetic/pharmacodynamic studies, MRI-centered primary outcomes, and/or inclusion of teenagers in the adult trials.

Abstract
A number of new disease-modifying therapies have recently been developed and approved for use in adult-onset multiple sclerosis. However, few treatment options are approved for patients with paediatric-onset multiple sclerosis. There are an increasing number of clinical trials evaluating the efficacy and safety of disease-modifying therapies in children and teens living with multiple sclerosis. Clinical trials are difficult to complete in rare diseases like paediatric-onset multiple sclerosis; however, it is critical to assess safety and monitoring in this vulnerable population by applying robust research methodology to randomized controlled clinical trials. Longer-term extension analyses are also needed to better evaluate the efficacy, dosing and long-term safety of adult disease-modifying therapy for use in paediatric-onset multiple sclerosis. Future research should focus on defining optimal first-line disease-modifying therapy in paediatric-onset multiple sclerosis as related to both efficacy and safety, improving recruitment and completion rates of clinical trials, identifying relevant biomarkers of disease activity, analysing outcome measures related to treatment response and assessing long-term safety for this unique population living with a chronic disease.
