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
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.

Front Neurosci 2024; 17:1305176. [PMID: 38287987 PMCID: PMC10822923 DOI: 10.3389/fnins.2023.1305176] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Accepted: 12/28/2023] [Indexed: 01/31/2024] Open
Abstract
Introduction Early identification of patients with a more unfavorable outcome in Multiple Sclerosis (MS) is crucial to optimize individualized treatment. Neutrophil-lymphocyte index (NLI) and monocyte-lymphocyte index (MLI) have been considered as potential biomarkers for disease prognosis. Our study aims to investigate the usefulness of NLI and MLI as predictors of relapse, disability progression, and lesion accumulation on magnetic resonance imaging (MRI) 1 year after diagnosis and treatment initiation, in pediatric-onset MS. Methods A retrospective single-center study was conducted, including patients with diagnosis of MS established in pediatric age (<18 years old), at least 1-year of follow-up, and a complete blood count (CBC) performed at diagnosis. We collected the nearest-to-diagnosis NLI and MLI, as well as clinical and imaging variables, at diagnosis and 12 months later. Our cohort was further dichotomized into two groups, based on the presence of relapses. Statistical significance was considered for p < 0.05. Results Eighteen patients (n = 18) were included. The relapsing group had higher mean, minimum, and maximum values for both NLI (5.17 ± 5.85, range: 1.57-11.92) and MLI (0.35 ± 0.22, range: 0.19-0.59), compared to the non-relapsing group (2.19 ± 1.63, range: 1.12-7.32 for NLI, and 0.24 ± 0.09, range: 0.14-0.44 for MLI). A higher percentage of patients in the relapsing group had increased NLI (>1.89, 66.7%) and MLI (>0.21, 66.7%) values than those in the non-relapsing group (46.7%). Patients who presented new T2-hyperintense lesions on MRI after 1 year of follow-up also had higher mean, minimum, and maximum values of both biomarkers. Patients who did not achieve No Evidence of Disease Activity-3 (NEDA-3) state exhibited higher values for both ratios. However, in our sample, no statistically significant correlations were found between MLI and NLI values and the clinical and imaging variables considered. Conclusion The ease of obtaining NLI and MLI from routine blood tests renders them useful biomarkers as a screening tool in longitudinal follow-up. Our study was based on a very small sample size, but it allowed us to verify the feasibility of the protocol used. It is intended to involve other centers in the next phase of this work, testing the possible usefulness of the indices under analysis on a larger sample.

Abstract
BACKGROUND Multiple Sclerosis (MS) is an immune-mediated, chronic disease of the central nervous system that affects mainly adults. However, it is increasingly recognized that MS may start in childhood resulting in a relentlessly progressive disability and cognitive impairment. Registries across the globe are reporting inconstant data about their Pediatric-Onset Multiple Sclerosis (POMS) patients. Moreover, newer lines of treatments are emerging and showing efficacy in controlling the MS disease regardless of the onset. Therefore, there is a requirement for more research into the clinical profile of POMS in different populations and ethnicities. METHODS This study was a cross-sectional study that included MS patients who visited the MS unit at Alexandria University from January 2019 to January 2021. We analyzed their epidemiological, clinical, radiological data, and cerebrospinal fluid (CSF) results from their updated records as well as follow-up interviews. RESULTS Annual Relapse Rate (ARR) was marginally less in POMS than AOMS (0.72 ± 0.57 vs 1.04 ± 0.78 relapse/year, P =.008). POMS patients had a bigger gap to their first relapse (40.0 ± 47.35 vs 22.71 ± 34.33 months, p= .066). The difference in relapse rate between the two groups was abolished after the exclusion of patients who had a gap of more than 5 years to their first relapse. AOMS patients were significantly more likely to start with a second-line disease-modifying treatment (DMT) than POMS patients (11.5% vs 31%, p= .04), whereas POMS patients were more likely to be escalated to the second line (34.6% vs 19.3%, p= .07). ARR had a positive and significant correlation with expanded disability status scale (EDSS) progression per year (rs(24)= .57 p=.003). A Mann-Whitney test indicated that POMS patients who had infratentorial involvement in the initial MRI brain had higher EDSS (3.08 ± 1.99) than POMS who did not (1.07 ± 0.79) U=24 P =.013. IgG index had a significant and positive correlation with annual EDSS progression rate rs (8) = 0.8 p=.001. CONCLUSION Early disease onset does not mean a higher relapse rate when including the full spectrum of POMS and longer follow-up duration. POMS patients relapsed more on the first-line DMT and escalation should be considered early. Infratentorial involvement in the initial magnetic resonance imaging (MRI) brain and high IgG index are potential predictors for aggressive disease course in POMS.

Abstract
PURPOSE OF REVIEW Multiple sclerosis is a chronic inflammatory disease of the central nervous system. When seen in children and adolescents, crucial stages of brain development and maturation may be affected. Prompt recognition of multiple sclerosis in this population is essential, as early intervention with disease-modifying therapies may change developmental trajectories associated with the disease. In this paper, we will review diagnostic criteria for pediatric multiple sclerosis, outcomes, differential diagnosis, and current therapeutic approaches. RECENT FINDINGS Recent studies have demonstrated the utility of newer structural and functional metrics in facilitating early recognition and diagnosis of pediatric MS. Knowledge about disease-modifying therapies in pediatric multiple sclerosis has expanded in recent years: important developmental impacts of earlier therapeutic intervention and use of highly effective therapies have been demonstrated. Pediatric MS is characterized by highly active disease and high disease burden. Advances in knowledge have led to early identification, diagnosis, and treatment. Lifestyle-related interventions and higher efficacy therapies are currently undergoing investigation.

Abstract
Acquired demyelinating syndromes of the central nervous system are immune-mediated demyelinating disorders that can affect the brain, optic nerves, and spinal cord. These disorders have become increasingly recognized in children due to advances in imaging techniques, improvements in diagnostic testing, extensive research into understanding the pathophysiology underlying these disorders, and collaborative multi-institutional efforts to raise awareness of these disorders in children. Moreover, developments in the field of neuroimmunology have allowed us to identify autoantibodies that have presumed causal roles in acquired demyelinating syndromes. Identification of these autoantibodies helps determine clinical course (ie, monophasic vs relapsing course), prognosis, and treatment approach. Acquired demyelinating disorders can affect both children and adults. However, the clinical features, disease course, and treatments are often unique in the pediatric population. Thus, it is important to understand the spectrum of these disorders in children to help provide a timely diagnosis and prompt treatment to achieve optimal outcomes. In this article, the epidemiology, clinical features, diagnosis, treatment, and outcomes of the most common monophasic acquired demyelinating syndromes in children will be reviewed.

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
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
The aim of this study is to examine the relationship between body mass index (BMI) and intelligence quotient scores (IQ). The sample included 11 patients with pediatric multiple sclerosis between 8 and 17 years, mean age 14.45 years (SD = 2.69). The BMI was calculated as weight in kilograms divided by the square of height in meters. The Wechsler Intelligence Scale for Children V and the Abbreviated Weschler Intelligence Scale were used to measure total IQ. Average sample BMI and IQ were 24.61 (SD = 5.53) (range: 19-39.4) and 86.63 (SD = 14.79) (range: 66-111), respectively. Results of the Pearson correlation indicated that there was a significant negative association between BMI and IQ, (r = -0.608, p = 0.042). R-squared was 0.370. We discuss if lower IQ lead to BMI gains or whether overweight/obesity lead to intellectual functioning changes. Implication for practice and future research are presented.

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
BackgroundRadiologically isolated syndrome (RIS) describes asymptomatic individuals with incidental radiologic abnormalities suggestive of multiple sclerosis (MS). Much of RIS literature is about adult-onset cases. Treatment of RIS is controversial, especially in pediatric age, but early treatment in selected patients might improve long-term outcomes.Case presentationWe report a single RIS patient who followed up for 18 years in our MS center. At first, she was only monitored with follow-up MRIs. Then, as the lesion load increased, she was treated with a first-line disease-modifying treatment (DMT) reaching MRI stability.ConclusionThis report highlights how treatment can be an appropriate choice in pediatric forms of RIS.

Abstract
BACKGROUND Ocrelizumab is a recombinant humanized anti-CD20 monoclonal IgG1, approved by FDA and EMA for adult patients with multiple sclerosis (MS). The data on the efficacy and safety of Ocrelizumab for pediatric MS cases are limited. OBJECTIVE Here, we describe pediatric relapsing-remitting MS (P-RRMS) cases who were treated with Ocrelizumab as a disease-modifying drug. METHOD P-RRMS cases who were started Ocrelizumab below 18 years-of-age and followed-up >12 months with Ocrelizumab treatment were included. The primary end-points were annualized relapse rate (ARR) and magnetic resonance imaging (MRI) activity (new/enlarging T2 lesions and new gadolinium (Gd) enhancing lesions). The secondary end-points were the percentage of patients who remain relapse-free and/or free from Gd enhancing lesions, Expanded Disability Status Scale (EDSS) score, and the safety profile of Ocrelizumab. RESULTS Of 18 P-RRMS cases receiving Ocrelizumab, 10 patients fulfilled the inclusion criteria for our study. The median duration of follow-up under Ocrelizumab was 28,3 months (min: 15 months, max: 46 months). Mean ARR decreased from 2.01 (±0.71) to 0 during the follow-up of Ocrelizumab treatment (P < 0.0001). None of the patients had MRI activity during the treatment. Mean EDSS decreased from 1.75 (±1.09) to 1.20 (±0.63) from the initiation of Ocrelizumab to the last follow-up of the patients (P = 0.024). None of the patients had serious side effects, except one patient who experienced anaphylaxis. CONCLUSION Ocrelizumab can be considered a safe and effective treatment option in highly active P-RRMS.

Re-examining the characteristics of pediatric multiple sclerosis in the era of antibody-associated demyelinating syndromes. Eur J Paediatr Neurol 2022; 41:8-18.

Abstract
BACKGROUND The discovery of anti-myelin oligodendrocyte glycoprotein (MOG)-IgG and anti-aquaporin 4 (AQP4)-IgG and the observation on certain patients previously diagnosed with multiple sclerosis (MS) actually have an antibody-mediated disease mandated re-evaluation of pediatric MS series. AIM To describe the characteristics of recent pediatric MS cases by age groups and compare with the cohort established before 2015. METHOD Data of pediatric MS patients diagnosed between 2015 and 2021 were collected from 44 pediatric neurology centers across Türkiye. Clinical and paraclinical features were compared between patients with disease onset before 12 years (earlier onset) and ≥12 years (later onset) as well as between our current (2015-2021) and previous (<2015) cohorts. RESULTS A total of 634 children (456 girls) were enrolled, 89 (14%) were of earlier onset. The earlier-onset group had lower female/male ratio, more frequent initial diagnosis of acute disseminated encephalomyelitis (ADEM), more frequent brainstem symptoms, longer interval between the first two attacks, less frequent spinal cord involvement on magnetic resonance imaging (MRI), and lower prevalence of cerebrospinal fluid (CSF)-restricted oligoclonal bands (OCBs). The earlier-onset group was less likely to respond to initial disease-modifying treatments. Compared to our previous cohort, the current series had fewer patients with onset <12 years, initial presentation with ADEM-like features, brainstem or cerebellar symptoms, seizures, and spinal lesions on MRI. The female/male ratio, the frequency of sensorial symptoms, and CSF-restricted OCBs were higher than reported in our previous cohort. CONCLUSION Pediatric MS starting before 12 years was less common than reported previously, likely due to exclusion of patients with antibody-mediated diseases. The results underline the importance of antibody testing and indicate pediatric MS may be a more homogeneous disorder and more similar to adult-onset MS than previously thought.

Abstract
IMPORTANCE With few approved multiple sclerosis therapies in the pediatric population, there is a need for further approved treatment options. Limited data exist for dimethyl fumarate (DMF) treatment in pediatric-onset multiple sclerosis (POMS). OBJECTIVE To compare the efficacy, safety, and tolerability of DMF vs intramuscular interferon β-1a (IFNβ-1a) in POMS. DESIGN, SETTING, AND PARTICIPANTS The CONNECT study was an active-controlled, open-label, rater-blinded 96-week randomized clinical trial in patients with POMS aged 10 to less than 18 years treated between August 2014 and November 2020. Data were analyzed from January through October 2021. INTERVENTIONS Patients were randomized to DMF or IFNβ-1a. MAIN OUTCOMES AND MEASURES The primary end point was the proportion of patients free of new or newly enlarging (N or NE) T2 hyperintense lesions at week 96 among trial completers. Secondary end points included number of N or NE T2 lesions, proportion of patients free of relapse, annualized relapse rate (ARR), and safety. The estimated proportion of participants who were relapse free up to week 96 was calculated based on the Kaplan-Meier method. Adjusted ARR was obtained from a negative binomial regression adjusted for baseline relapse rate, baseline Expanded Disability Status Scale (EDSS) score, and age group. RESULTS Among 150 patients with POMS in the intention-to-treat (ITT) population (median [range] age, 15 [10-17] years; 101 [67.3%] female patients), 78 individuals received DMF and 72 individuals received IFNβ-1a. At week 96, the proportion of patients with no N or NE T2 hyperintense lesions among 103 trial completers was 16.1% (95% CI, 8.0%-27.7%) for DMF vs 4.9% (95% CI, 0.6%-16.5%) for IFNβ-1a, and in a sensitivity analysis among the ITT population, the proportions were 10 patients receiving DMF (12.8%) vs 2 patients receiving IFNβ-1a (2.8%). The estimated proportion of patients who remained relapse free at week 96 was 66.2% for DMF vs 52.3% for IFNβ-1a. Adjusted ARR (95% CI) at week 96 was 0.24 (95% CI, 0.15-0.39) for DMF vs 0.53 (95% CI, 0.33-0.84) for IFNβ-1a; the rate ratio for DMF vs IFNβ-1a was 0.46 (95% CI, 0.26-0.80; P = .006). The number of treatment-emergent adverse events (TEAEs; 74 patients [94.9%] vs 69 patients [95.8%]), serious TEAEs (18 patients [23.1%] vs 21 patients [29.2%]), and treatment discontinuations due to TEAEs (5 patients [6.4%] vs 8 patients [11.1%]) was similar for DMF vs IFNβ-1a. CONCLUSIONS AND RELEVANCE This study found that more pediatric patients with POMS treated with DMF were free of new or newly enlarging T2 lesions and that the adjusted ARR was lower among these patients compared with those treated with interferon β-1a. DMF was well tolerated. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02283853.

Abstract
Multiple sclerosis (MS) most commonly presents in young adults, although 3-5% of patients develop MS prior to the age of 18 years. The new and comprehensive consensus for the management of MS in Saudi Arabia includes recommendations for the management of MS and other CNS inflammatory demyelinating disorders in pediatric and adolescent patients. This article summarizes the key recommendations for the diagnosis and management of these disorders in young patients. Pediatric and adult populations with MS differ in their presentation and clinical course. Careful differential diagnosis is important to exclude alternative diagnoses such as acute disseminated encephalomyelitis (ADEM) or neuromyelitis optica spectrum disorders (NMOSD). The diagnosis of MS in a pediatric/adolescent patient is based on the 2017 McDonald diagnostic criteria, as in adults, once the possibility of ADEM or NMOSD has been ruled out. Few data are available from randomized trials to support the use of a specific disease-modifying therapy (DMT) in this population. Interferons and glatiramer acetate are preferred initial choices for DMTs based on observational evidence, with the requirement of a switch to a more effective DMT if breakthrough MS activity occurs.

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.

Trends in the use of disease-modifying therapies among reproductive-aged women with multiple sclerosis in the United States from 2010 to 2019. Pharmacoepidemiol Drug Saf 2022; 31:481-487. [PMID: 35088492 DOI: 10.1002/pds.5411] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2021] [Revised: 01/04/2022] [Accepted: 01/21/2022] [Indexed: 02/05/2023]
Abstract
PURPOSE Multiple sclerosis (MS) is a chronic disease of the central nervous system that disproportionately affects women, with typical onset during reproductive age. Several disease-modifying therapies (DMTs) are FDA-approved to slow disease progression, but are not indicated for use during pregnancy. Our objective was to describe trends over time (2010-2019) in monthly point prevalence of DMT use among reproductive-age women, overall and by generic name. METHODS This study used administrative claims data from the US during 2009-2019 to identify women age 15-44 with MS and continuous insurance coverage for ≥12 months. DMTs were identified using prescription fills and procedural claims for alemtuzumab, daclizumab, dimethyl fumarate, fingolimod, glatiramer acetate, interferon beta, mitoxantrone, natalizumab, ocrelizumab, and teriflunomide. Monthly prevalent use was defined as ≥1 days' supply of a DMT in the month. Age- and region-standardized monthly prevalence was estimated nonparametrically. RESULTS Among 42 281 reproductive-aged women over 818 179 person-months, DMT use increased from a minimum monthly prevalence of 49.3% (February, 2011) to a maximum of 58.7% (April, 2019). In 2010, prevalence of injectable DMTs was 43.1% compared to 2.5% for oral DMTs; by 2014, however, oral DMTs (26.5%) surpassed injectable DMTs (23.7%) as the most common route of administration. In the most recent data available (December, 2019), the most common DMTs were dimethyl fumarate, glatiramer acetate, and fingolimod. CONCLUSIONS DMT use among reproductive-aged women has rapidly evolved during the past decade. Collaborative treatment decision making between women with MS and clinicians may help optimize MS care and improve DMT uptake during reproductive years.

Abstract
Multiple sclerosis (MS) is the most common autoimmune, chronic inflammatory demyelinating disorder of the central nervous system. Pediatric-onset MS (POMS), as opposed to adult-onset MS (AOMS), is a rare condition, presenting similar clinical features to AOMS, but a more active course of the disease, with higher relapse rates and greater white and grey matter damage. To date, the therapeutic approaches to treat POMS have been extrapolated from observational studies and data from trials conducted on adults, raising concerns about their efficacy and safety in the pediatric population. Herein, we discuss the most common therapeutic strategies used in POMS management, basing on the individual clinical practice and experience.

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.

Safety and efficacy of teriflunomide in paediatric multiple sclerosis (TERIKIDS): a multicentre, double-blind, phase 3, randomised, placebo-controlled trial. Lancet Neurol 2021; 20:1001-1011. [PMID: 34800398 DOI: 10.1016/s1474-4422(21)00364-1] [Citation(s) in RCA: 40] [Impact Index Per Article: 13.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Revised: 09/17/2021] [Accepted: 10/12/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND Therapeutic options for children with multiple sclerosis are scarce. Teriflunomide is approved in more than 80 countries for the treatment of adults with relapsing multiple sclerosis. The TERIKIDS study examined the safety and efficacy of teriflunomide in children with relapsing multiple sclerosis. METHODS The TERIKIDS trial was a multicentre, phase 3, double-blind, parallel-group, randomised, placebo-controlled study conducted at 57 clinical centres in 22 countries in Asia, Europe, the Middle East, North Africa, and North America. The trial enrolled patients aged 10-17 years, diagnosed with relapsing multiple sclerosis and with at least one relapse in the year preceding screening or at least two relapses in the 2 years preceding screening. Patients were randomly assigned (2:1) to oral teriflunomide (dosage equivalent to 14 mg in adults) or matching placebo, using an interactive web and voice response system, for up to 96 weeks. Personnel in all sites and all patients were masked to study treatment in the double-blind period. Early entry into a subsequent 96-week open-label extension phase was possible before the end of the double-blind period for patients with confirmed clinical relapse or high MRI activity (at least five new or enlarged T2 lesions at week 24, followed by at least nine new or enlarged T2 lesions at week 36, or at least five new or enlarged T2 lesions at weeks 36 and 48, or at weeks 48 and 72). The primary endpoint was time to first confirmed clinical relapse by the end of the double-blind period. Key secondary imaging endpoints were number of new or enlarged T2 lesions and number of gadolinium-enhancing lesions per MRI scan. Efficacy endpoints were analysed in the intention-to-treat population, and safety was assessed in all patients randomly assigned to treatment and exposed to the double-blind study medication. This study is registered with ClinicalTrials.gov (trial number NCT02201108) and is closed to recruitment, but an additional optional open-label extension is ongoing. FINDINGS Between July 24, 2014, and the date of last patient visit on Oct 25, 2019, 185 patients were screened for eligibility, 166 (90%) were enrolled, and 109 were randomly assigned teriflunomide and 57 were randomly assigned placebo. 102 (94%) of 109 and 53 (93%) of 57 completed the double-blind period. Switch to the ongoing open-label extension because of high MRI activity was more frequent than anticipated in the placebo group (14 [13%] of 109 patients in the teriflunomide group vs 15 [26%] of 57 in the placebo group), decreasing the power of the study. After 96 weeks, there was no difference in time to first confirmed clinical relapse with teriflunomide compared with placebo (hazard ratio 0·66, 95% CI 0·39-1·11; p=0·29). Teriflunomide reduced the number of new or enlarged T2 lesions versus placebo by 55% (relative risk 0·45, 95% CI 0·29-0·71; p=0·00061), and the number of gadolinium-enhancing lesions by 75% (relative risk 0·25, 0·13-0·51; p<0·0001). Adverse events occurred in 96 (88%) patients in the teriflunomide group and 47 (82%) patients in the placebo group; serious adverse events occurred in 12 (11%) patients in the teriflunomide group and 6 (11%) patients in the placebo group. Nasopharyngitis, upper-respiratory-tract infection, alopecia, paraesthesia, abdominal pain, and increased blood creatine phosphokinase were more frequent with teriflunomide than with placebo. During the double-blind phase, four patients in the teriflunomide group had pancreatic adverse events (two with acute pancreatitis and two with pancreatic enzyme elevation), of which three events led to treatment discontinuation. INTERPRETATION No significant difference in time to first confirmed clinical relapse was found, possibly because more patients than expected switched from the double-blind to the open-label treatment period because of high MRI activity. Key secondary imaging analyses and a prespecified sensitivity analysis of probability of relapse or high MRI activity suggest that teriflunomide might have beneficial effects in children with relapsing multiple sclerosis by reducing the risk of focal inflammatory activity.

Abstract
BACKGROUND Pediatric autoimmune diseases affecting the central nervous system have recently come into the the focus of attention. Important advances have been made in the field of children with multiple sclerosis (MS), which led to a better understanding of the clinical characteristics and treatment options. Furthermore, new autoantibodies against target antigens of neurons, peripheral nerves and the myelin sheath have been detected. OBJECTIVE This article summarizes new advances in children with MS and addresses the differences to their adult counterparts. In addition, the most important forms of autoimmune encephalitis, such as N‑methyl D‑aspartate receptor (NMDA-R) or myelin oligodendrocyte glycoprotein (MOG) encephalitis in children are described together with the diagnostic algorithm and therapeutic approach in the event of a suspected autoimmune encephalitis. Lastly, the clinical spectrum of MOG antibody-associated diseases (MOGAD) is detailed.

Abstract
BACKGROUND Only recently has the first disease-modifying therapy been approved for children with multiple sclerosis (MS) and practice patterns including substantial off-label use have evolved. Understanding attitudes towards treatment of paediatric MS and whether this has changed due to the ongoing COVID-19 pandemic is vital to guide future therapeutic trials and for developing guidelines that reflect practice. METHODS We performed an online survey within the International Paediatric Multiple Sclerosis Study Group between July and September 2020. The survey was sent to 130 members from 25 countries and consisted of five sections: demographic data, treatment, disease modifying therapies and COVID-19, outcome and three patient cases. RESULTS The survey was completed by 66 members (51%), both paediatric neurologists and adult neurologists. Fingolimod and β-interferons were the most frequently used disease-modifying therapies, especially among paediatric neurologists. Almost a third (31%) of respondents had altered their prescribing practice due to COVID-19, in particular at the beginning of the pandemic. CONCLUSIONS The survey results indicate a tendency of moving from the traditional escalation therapy starting with injectables towards an early start with newer, highly effective disease modifying therapies. The COVID-19 pandemic only slightly affected prescribing patterns and treatment choices in paediatric MS.

Fingolimod as a first- or second-line treatment in a mini-series of young Hellenic patients with adolescent-onset multiple sclerosis: focus on immunological data. Neurol Sci 2021; 43:2641-2649.

Abstract
BACKGROUND Pediatric onset multiple sclerosis(POMS) is characterized by a highly active profile, often warranting treatment with high efficacy disease-modulating therapies (DMTs). Fingolimod, an oral sphingosine-1-phosphate receptor modulator, is the first Food and Drug Administration (FDA)- and European Medicines Agency (EMA)-approved DMT for the treatment of POMS. OBJECT Our aim is to present real-world data of seven fingolimod-treated POMS-patients, recruited in a single MS center in Greece. METHODS Clinical and imaging/laboratory data from 7 Hellenic patients fulfilling the International Pediatric Multiple Sclerosis Study Group (IPMSSG) criteria for POMS diagnosis, who have received fingolimod treatment, were selected. Human leukocyte antigen (HLA) genotyping was performed with standard low-resolution sequence-specific oligonucleotide techniques. RESULTS Three patients were treatment-naïve adolescents who received fingolimod as first-line treatment. Two experienced ongoing clinical and radiological disease activity and have been switched to natalizumab. The remaining cases were post-adolescent adults with POMS, where the vast majority experienced total/near-total disease remission. Fingolimod was generally well-tolerated. Two patients with high disease activity carried the HLA-DRB1*03 allele, while five patients were carriers of at least one of the HLA-DRB1*04, HLA-DRB1*13, and HLA-DRB1*14 alleles, which when not combined with HLA-DRB1*03 showed a trend towards a more favorable clinical course. Fingolimod responders showed a trend towards increased CD(16-56)+NK cell counts in immunophenotyping assays. CONCLUSIONS Our preliminary results support that response of POMS patients to fingolimod may be partially dependent on age and previous DMT, with younger and treatment-naïve patients presenting worse outcomes. The role of immunogenetics and immunophenotyping in personalized treatment warrants investigation in larger and more diverse populations.

Abstract
Pediatric new drug trials are federally mandated, but family perspectives in multiple sclerosis (MS) research are limited. Due to MS chronicity and long-term medical system involvement, we obtained family views on research priorities and optimized methods for future studies. Focus groups were convened with families impacted by pediatric-onset MS. Recruitment included those followed by the Network of Pediatric MS Centers, geographically disparate locations, and centers' voluntary election. Study questions included: healthcare experiences, clinical trials perspectives, cognitive/psychosocial/educational outcomes, disease course and disability accrual. All subjects supported future clinical studies. Patients highlighted contribution to knowledge base but were wary of experimental medication and disease-course impeding activities. Parents underscored medication delivery modalities, side-effects, and limiting children's discomfort. All wanted study relevance made explicit. Suggested future study design elements included: providing compensation, limiting assumptions regarding outcome linkages, understanding study-related psychological impacts, and reducing participation burdens. Rare disease research can assist general medicine diagnosis and referral. Variable study designs and explicit rationale may augment participation. Closing the pediatric research gap requires family engagement in the research process.

Abstract
Purpose: To report the case of a 14-year-old female patient with one-and-a-half syndrome subsequently diagnosed with multiple sclerosis involving the pons.Case summary: A 14-year-old girl without any underlying disease presented with difficulty focusing and mild headache for 5 days. The patient showed conjugate gaze palsy to the left, limited adduction in the left eye, and abducting nystagmus in the right eye, which indicated one-and-half syndrome. T2 fluid-attenuated inversion recovery brain magnetic resonance imaging revealed multiple punctate hyperintensities in the pontine tegmentum, bilateral cerebral white matter, and cerebellum. Cerebrospinal fluid examination revealed oligoclonal bands and multiple sclerosis was diagnosed. The patient was treated with intravenous steroids and beta-interferon. Seven weeks later, limitation of eyeball movement and nystagmus had resolved completely.Conclusions: At the young age of 14 years, a patient presenting with one-and-a-half syndrome was diagnosed with multiple sclerosis. Children with multiple sclerosis may experience severe physical and cognitive impairments, and brainstem involvement predicts an especially poor prognosis. Early diagnosis and active treatment may help to prevent poor outcomes.

Abstract
Multiple sclerosis is a major socio-economical burden as it represents the most common cause of non-traumatic neurological disability in young adults [1]. It affects also children with a lower prevalence and incidence but remains a major concern as disability may occur later during their adulthood. Therefore, there is an absolute need for earlier diagnosis and treatment. In this review, we would focus on how these objectives can be achieved.

Abstract
Importance Availability of new disease-modifying therapies (DMTs) and changes of therapeutic paradigms have led to a general improvement of multiple sclerosis (MS) prognosis in adults. It is still unclear whether this improvement also involves patients with pediatric-onset MS (POMS), whose early management is more challenging. Objective To evaluate changes in the prognosis of POMS over time in association with changes in therapeutic and managing standards. Design, Setting, and Participants Retrospective, multicenter, observational study. Data were extracted and collected in May 2019 from the Italian MS Registry, a digital database including more than 59 000 patients. Inclusion criteria were MS onset before age 18 years, diagnosis before January 2014, and disease duration of at least 3 years. Exclusion criteria were primary progressive MS, Expanded Disability Status Scale (EDSS) score of at least 8 one year after onset, unavailability of diagnosis date, and less than 2 EDSS score evaluations. Eligible patients were 4704 patients with POMS. According to these criteria, we enrolled 3198 patients, excluding 1506. Exposures We compared time to reach disability milestones by epoch of MS diagnosis (<1993, 1993-1999, 2000-2006, and 2007-2013), adjusting for possible confounders linked to EDSS evaluations and clinical disease activity. We then analyzed the difference among the 4 diagnosis epochs regarding demographic characteristics, clinical disease activity at onset, and DMTs management. Main Outcomes and Measures Disability milestones were EDSS score 4.0 and 6.0, confirmed in the following clinical evaluation and in the last available visit. Results We enrolled 3198 patients with POMS (mean age at onset, 15.2 years; 69% female; median time to diagnosis, 3.2 years; annualized relapse rate in first 1 and 3 years, 1.3 and 0.6, respectively), with a mean (SD) follow-up of 21.8 (11.7) years. Median survival times to reach EDSS score of 4.0 and 6.0 were 31.7 and 40.5 years. The cumulative risk of reaching disability milestones gradually decreased over time, both for EDSS score of 4.0 (hazard ratio [HR], 0.70; 95% CI, 0.58-0.83 in 1993-1999; HR, 0.48; 95% CI, 0.38-0.60 in 2000-2006; and HR, 0.44; 95% CI, 0.32-0.59 in 2007-2013) and 6.0 (HR, 0.72; 95% CI, 0.57-0.90; HR, 0.44; 95% CI, 0.33-0.60; and HR, 0.30; 0.20-0.46). In later diagnosis epochs, a greater number of patients with POMS were treated with DMTs, especially high-potency drugs, that were given earlier and for a longer period. Demographic characteristics and clinical disease activity at onset did not change significantly over time. Conclusions and Relevance In POMS, the risk of persistent disability has been reduced by 50% to 70% in recent diagnosis epochs, probably owing to improvement in therapeutic and managing standards.

Abstract
Treatment of pediatric-onset multiple sclerosis (POMS) has been tailored after observational studies and data obtained from clinical trials in adult-onset multiple sclerosis (AOMS) patients. There are an increasing number of new therapeutic agents for AOMS, and many will be formally studied for use also in POMS. However, there are important efficacy and safety concerns regarding the use of these therapies in children and young adults. This review will discuss the current state of the art of POMS therapy and will focus on the newer therapies (oral and infusion disease-modifying drugs) and on those still currently under investigation.

Abstract
To evaluate the clinical and neuroimaging features of pediatric acquired demyelinating syndromes (ADS) in a tertiary pediatric neurology clinic in Turkey. All children diagnosed with any subset of ADS between 2013 and 2018 were included in this retrospective cohort study. Forty-two patients (21 female) with a median follow-up period of 30 months were included. The median age of the patients at disease onset was 11 years (range 1.5-17 years). The most common pediatric ADS categories according to the International pediatric Multiple Sclerosis Study Group consensus classification criteria were acute disseminated encephalomyelitis (ADEM) and multiple sclerosis (MS), each of which seen in 15 patients, followed by clinically isolated syndrome (CIS) (n = 11) and Neuromyelitis Optica Spectrum Disorder (NMOSD) (n = 1). At the first clinical event, children with ADEM significantly differed from the children affected by MS and CIS in terms of the following parameters: median age at onset (7 vs. 13.5 and 14.5 years; p < 0.001), encephalopathy (93.3 vs 0% and 0%; p < 0.001), and basal ganglia/thalamus lesions (73.3 vs 9.1% and 9.1%; p < 0.001). The frequency of seizure and pleocytosis were higher in ADEM group than MS group (p < 0.05), whereas oligoclonal bands (p < 0.001) and periventricular white matter lesions (p < 0.01) were more frequently observed in MS patients. Rituximab was used with great success in the prevention of relapses in 3 patients: NMOSD (n = 1), MS (n = 1) and ADEM followed by recurrent optic neuritis (n = 1). Our results define the longitudinal disease course of various ADS categories in a single referral center. In addition, this study compares various clinical, laboratory and neuroimaging features between these ADS categories.

Abstract
The emerging paradigm of childhood autoimmune neurological disorders has exploded in recent times due to reliable diagnostic methods and their ease of availability, well-defined diagnostic criteria, and universal awareness about these disorders. The most important aspect of these disorders is a considerable recovery in response to early targeted immunotherapy. If left untreated and/or ill-treated, these can lead to mortality or lifelong morbidity. Autoantibodies can target any part of the central nervous system (CNS), ranging from superficial structures like myelin to deep intracellular ion channels like voltage-gated potassium channels, resulting in contrasting and at times overlapping symptomatology. Though neuroimaging characteristics and serological tests confirm these disorders' diagnosis, it is essential to suspect them clinically and start management before the reports are available for minimizing morbidity and mortality. In the pediatric age group, several metabolic conditions, like mitochondrial disorders and enzyme deficiencies like HMG-CoA-lyase deficiency, can develop neuroimaging patterns similar to those seen in childhood CNS autoimmune disorders and may also show a favorable response to steroids in acute phases. Hence, the clinician must suspect and work up the index patient appropriately. Here, we briefly discuss the pathophysiology, clinical clues, and potential therapeutic targets related to pediatric CNS autoimmune disorders.

Long-term fingolimod treatment in two pediatric patients with multiple sclerosis. Neurol Sci 2021; 42:29-36.

Abstract
Data suggest that patients with pediatric-onset multiple sclerosis (POMS) should initiate treatment with a disease-modifying therapy early to slow progression. The PARADIGMS trial demonstrated that oral fingolimod reduced the annual rate of relapse by 82% compared with intramuscular interferon beta-1a in children with POMS. The PARADIGMS study had a follow-up of 2 years, but no data are available about the safety and efficacy of fingolimod for longer periods in children with POMS. Here we present two cases of children with POMS who achieved sustained clinical benefit from treatment with fingolimod for more than 2 years. The first patient, an 11-year-old male, who participate in the PARADIGMS study, was treatment naïve at the time of fingolimod initiation. His clinical condition remained stable over 5 years of treatment, with no relapses and no radiological lesion progression. The second patient was a female who initiated fingolimod at the age of 12 years, 2 years after her POMS diagnosis and after an 8-month trial of interferon beta-1a. The patient had experienced two relapses during interferon beta-1a but had no relapses in more than 2 years of treatment with fingolimod, and her MRI scans showed no new or active lesions. These data show that prolonged treatment with fingolimod can be safe and effective during long-term treatment as first- or second-line therapy in children with POMS.

Abstract
Pediatric-onset multiple sclerosis (MS) has a highly active and aggressive course, which can have a devastating effect on the physical and cognitive functioning of a child if not treated appropriately with effective disease-modifying drugs. The optimal treatment strategy of pediatric MS is currently unknown and debate continues as to whether treatment escalation or initiation of a highly active therapy provides a better outcome. Here, we present the case of a 16-year-old female diagnosed with highly active relapsing-remitting MS (age at onset: 14 years) who received first-line treatment with fingolimod within 1 year of the first recorded symptom. Since starting fingolimod, the course of the disease has essentially been stable. No new or active lesions were observed in magnetic resonance imaging scans performed at 3 and 12 months after starting fingolimod, and treatment was well tolerated. These data suggest that, in this case, early treatment with first-line fingolimod was able to slow disease progression.

Abstract
BACKGROUND A significant proportion of pediatric-onset multiple sclerosis (POMS) patients do not respond to first-line disease-modifying therapies. Clinical trials showed that natalizumab is effective and safe in adults, but there are limited clinical trial data for children. Natalizumab is currently prescribed off-label for POMS. We aimed to characterize the effectiveness, safety and tolerability of natalizumab in all POMS cases treated in Portugal (from 2007 to 2018). METHODS Data from clinical records were retrospectively collected for all POMS cases treated with natalizumab in Portugal. RESULTS Twenty-one patients were included, 14 (67%) of which were female. The median age at POMS diagnosis was 13 years old. The median duration of treatment with natalizumab was 2 years and 3 months. Median Expanded Disability Status Scale score decreased from 1.5 to 1.0 after 24 months. The Annualized Relapse Rate decreased from 1.31 events/patient/year before treatment with natalizumab to 0 after 12 months of treatment and to 0.04 after 24 months. No gadolinium-enhancing lesions or new or enlarged T2 hyperintense lesions were observed in 8/8 patients (100%) after 12 months, and 4/5 (80%) after 24 months. There was one possible serious adverse event, which did not require dose adjustment. Five patients discontinued treatment due to positive anti-JCV (JC virus) antibody JC serostatus. CONCLUSION Natalizumab may be an effective and safe disease-modifying therapy for POMS. Our results are in line with data published for the adult population, as well as with similar observational studies in pediatric populations in other regions.

Abstract
AIMS To evaluate the cost-effectiveness of fingolimod versus interferon (IFN)-β1a at a dose of 30 μg per week for the treatment of relapsing pediatric-onset multiple sclerosis (POMS) in Canada. MATERIAL AND METHODS A discrete-time Markov model was developed to compare fingolimod with IFN β-1a over a time horizon of two years representing patients followed up to mean age of 18 years from a Canadian health care system perspective. Twenty-one health states based on the Expanded Disability Status Scale (EDSS) were considered: EDSS 0‒9 for relapsing multiple sclerosis (MS), EDSS 0‒9 for secondary progressive MS, and "Death." Relative treatment efficacy for fingolimod versus IFN-β1a was estimated from the PARADIGMS study. Costs and resource use were obtained from published literature and Canadian sources. Utilities were estimated by mapping the Pediatric Quality of Life inventory data onto the Child Health Utility Index-9 Dimension using a published mapping algorithm. Future costs and benefits were discounted at 1.5% per annum. RESULTS Compared with IFN β-1a, fingolimod led to an increase in quality-adjusted life-years (QALYs) (0.125) with incremental costs (Canadian dollars [CAD] 2,977) and to an incremental cost-effectiveness ratio (ICER) of CAD 23,886/QALY over a time horizon of two years representing patients followed up to mean age of 18 years. The monetary benefits of fingolimod treatment versus IFN β-1a at a willingness-to-pay (WTP) threshold of CAD 50,000 per QALY gained were higher than the costs. One-way sensitivity analysis and probabilistic sensitivity analysis (PSA) both confirmed the robustness of the results. LIMITATIONS The main limitations of this analysis primarily stem from the limited data availability in POMS. CONCLUSIONS Fingolimod is cost effective compared with IFN β-1a for the treatment of POMS over a time horizon of two years representing patients followed up to a mean age of 18 years in Canada.

Abstract
Considerable progress has been made in the understanding and treatment of paediatric-onset multiple sclerosis (POMS); how this has translated into more effective care is less well understood. Here, we evaluate how recent advances have affected patient management and outcomes with a retrospective review of POMS patients managed at two paediatric neuroimmunology centres. Two cohorts, seen within a decade, were compared to investigate associations between management approaches and outcomes. Demographic, clinical and neurocognitive data were extracted from case notes and analysed. Of 51 patients, 24 were seen during the period 2007-2010 and 27 during the period 2015-2016. Median age at onset was 13.7 years; time from symptom onset to diagnosis was 9 months. Disease-modifying therapies were commenced in 19 earlier-cohort and 24 later-cohort patients. Median time from diagnosis to treatment was 9 months for earlier vs. 3.5 months in later patients (p = 0.013). A wider variety of treatments were used in the later cohort (four medications earlier vs. seven in the later and two clinical trials), with increased quality of life and neurocognitive monitoring (8% vs. 48% completed PedsQL quality of life inventory; 58% vs. 89% completed neurocognitive assessment). In both cohorts, patients were responsive to disease-modifying therapy (mean annualised relapse rate pre-treatment 2.7 vs. 1.7, mean post-treatment 0.74 vs. 0.37 in earlier vs. later cohorts). In conclusion, over the years, POMS patients were treated sooner with a wider variety of medications and monitored more comprehensively. However, this hugely uncontrolled cohort did not allow us to identify key determinants for the improvements observed.

Abstract
Abstract
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). We included patients with a relapsing-remitting phenotype, ≥5 years follow-up, ≥3 Expanded Disability Status Scale (EDSS) evaluations and a first neurological evaluation within 3 years from the first demyelinating event. Multivariate Cox regression models (adjusted hazard ratio with 95% confidence intervals) were used to assess the risk of reaching a first 12-month confirmed disability worsening and the risk of reaching a sustained EDSS of 4.0. The effect of disease-modifying drugs was assessed as quartiles of time exposure. We found that disease-modifying drugs reduced the risk of 12-month confirmed disability worsening, with a progressive risk reduction in different quartiles of exposure in paediatric-onset and adult-onset patients [adjusted hazard ratios in non-exposed versus exposed >62% of the follow-up time: 8.0 (3.5–17.9) for paediatric-onset and 6.3 (4.9–8.0) for adult-onset, P < 0.0001] showing a trend in late-onset patients [adjusted hazard ratio = 1.9 (0.9–4.1), P = 0.07]. These results were confirmed for a sustained EDSS score of 4.0. We also found that relapses were a risk factor for 12-month confirmed disability worsening in all three cohorts, and female sex exerted a protective role in the late-onset cohort. This study provides evidence that sustained exposure to disease-modifying drugs decreases the risk of disability accumulation, seemingly in a dose-dependent manner. It confirms that the effectiveness of disease-modifying drugs is lower in late-onset patients, although still detectable.

Abstract
OBJECTIVE To characterize disease severity and distribution of disability in pediatric-onset multiple sclerosis (POMS) and to develop an optimized modeling scale for measuring disability, we performed a multicenter retrospective analysis of disability scores in 873 persons with POMS over time and compared this to previously published data in adults with multiple sclerosis (MS). METHODS This was a retrospective analysis of prospectively collected data collected from 12 centers of the US Network of Pediatric MS Centers. Patients were stratified by the number of years from first symptoms of MS to Expanded Disability Status Scale (EDSS) assessment and an MS severity score (Pediatric Multiple Sclerosis Severity Score [Ped-MSSS]) was calculated per criteria developed by Roxburgh et al. in 2005. RESULTS In total, 873 patients were evaluated. In our cohort, 52%, 19.4%, and 1.5% of all patients at any time point reached an EDSS of 2.0, 3.0, and 6.0. Comparison of our Ped-MSSS scores and previously published adult Multiple Sclerosis Severity Scores (MSSS) showed slower progression of Ped-MSSS with increasing gaps between higher EDSS score and years after diagnosis. Decile scores in our POMS cohort for EDSS of 2.0, 3.0, and 6.0 were 8.00/9.46/9.94, 7.86/9.39/9.91, and 7.32/9.01/9.86 at 2, 5, and 10 years, respectively. Notable predictors of disease progression in both EDSS and Ped-MSSS models were ever having a motor relapse and EDSS at year 1. Symbol Digit Modalities Test (SDMT) scores were inversely correlated with duration of disease activity and cerebral functional score. CONCLUSIONS Persons with POMS exhibit lower EDSS scores compared to persons with adult-onset MS. Use of a Ped-MSSS model may provide an alternative to EDSS scoring in clinical assessment of disease severity and disability accrual.

Abstract
Paediatric multiple sclerosis (MS) is associated with higher relapse rate, rapid magnetic resonance imaging lesion accrual early in the disease course and worse cognitive outcome and physical disability in the long term compared to adult-onset disease. Current treatment strategies are largely centre-specific and reliant on adult protocols. The aim of this review is to examine which treatment options should be considered first line for paediatric MS and we attempt to answer the question if injectable first-line disease-modifying therapies (DMTs) are still an optimal option. To answer this question, we review the effects of early onset disease on clinical course and outcomes, with specific considerations on risks and benefits of treatments for paediatric MS. Considering the impact of disease activity on brain atrophy, cognitive impairment and development of secondary progressive MS at a younger age, we would recommend treating paediatric MS as a highly active disease, favouring the early use of highly effective DMTs rather than injectable DMTs.

Abstract
Anti-CD20 therapies have established efficacy in the treatment of immune-mediated neurological and non-neurological diseases. Rituximab, one of the first B-cell-directed therapies, is relatively inexpensive compared to newer anti-CD20 molecules, is available in many countries, and has been used off-label in pediatric patients with neuroimmune conditions. The objective of this paper is to describe the experience with rituximab in pediatric multiple sclerosis and other inflammatory immune-mediated disorders of the central nervous system (CNS), and to define a protocol for its use in clinical practice, in particular addressing doses, interval of administration, duration of treatment, and tests to perform at baseline and during follow-up.

Abstract
Disease-modifying drugs (DMDs) for multiple sclerosis (MS) have been evaluated in pediatric patients in observational studies demonstrating a similar, even better clinical effect compared to adults, with a similar safety. Only fingolimod has been tested in a randomized controlled trial (RCT) and is approved for pediatric multiple sclerosis (ped-MS). Numerous methodological, practical, and ethical issues underline that RCTs are difficult to conduct in ped-MS. This also creates a lack of safety information. To facilitate the availability of new agents in ped-MS, we encourage to develop a different approach based on pharmacokinetic/pharmacodynamic studies to yield information on optimal doses and implementation of obligatory registries to obtain information on safety as primary endpoint.

Abstract
Background The current landscape and treatment patterns of disease-modifying therapy (DMT) use in pediatric patients with multiple sclerosis (MS) are not yet well understood. This study examined DMT utilization and treatment patterns in pediatric patients newly diagnosed as having MS. Methods Pediatric patients (<18 years old) with two MS diagnosis claims from January 1, 2010, to December 31, 2016, were identified from the MarketScan Commercial Database. The index date was defined as the date of first MS diagnosis, and patients were followed up for 1 year post-index date. Outcomes evaluated included percentage of patients who initiated treatment after MS diagnosis, different DMTs initiated, treatment discontinuation, and switching treatment during follow-up. Results Of 182,057 patients newly diagnosed as having MS, 288 pediatric patients (mean age, 14 years; 61% female) were identified. Within the first year of diagnosis, 188 patients (65.3%) did not receive any DMT. The most common first-initiated treatments were interferons and glatiramer acetate (83%), but 28% of patients switched or discontinued from first-initiated treatment within 6 months of treatment initiation. Conclusions This study suggests that a considerable proportion of pediatric patients with MS remain untreated within 1 year of diagnosis. Patients most commonly initiated injectables as their first DMT. Overall, therapy failed early in approximately one in three patients. Thus, the study warrants urgency in treating these patients with currently approved treatment options.

Abstract
Pediatric multiple sclerosis (MS) deserves special attention because of its impact on cognitive function and development. Although knowledge regarding pediatric MS has rapidly increased, understanding the peculiarities of this population remains crucial for disease management. There is limited expertise about the efficacy and safety of current disease-modifying agents. Although pathophysiology is not entirely understood, some risk factors and immunological features have been described and are discussed herein. While the revised International Pediatric MS Study Group diagnostic criteria have improved the accuracy of diagnosis, the recently revised McDonald criteria also offer some new insights into the pediatric population. It is fundamental that radiologists have strong knowledge about the vast spectrum of demyelinating disorders that can occur in childhood to ensure appropriate diagnosis and provide early treatment.

Abstract
Introduction: The World Health Organization (WHO) publishes a biennial Essential Medicines List (EML) to assist governments in low-resource settings to prioritize their spending on medicines. Currently, no medicines on the EML have a multiple sclerosis (MS) indication. Multiple Sclerosis International Federation (MSIF) prepared an application for inclusion of MS disease-modifying therapies (DMTs) for the 2019 EML together with the regional Committees for Treatment and Research in Multiple Sclerosis (TRIMS) and the World Federation of Neurology. Rationale: The MSIF taskforce categorized 15 DMTs according to their efficacy and risk profiles to ensure the ability to treat as many different clinical scenarios as possible. Three DMTs were selected: glatiramer acetate, fingolimod, and ocrelizumab. Outcome: The WHO Expert Committee did not recommend the addition of any of the DMTs to the EML. They acknowledged the public health burden of MS, the need for effective and affordable MS medications, and the high volume of letters received in support of the application but requested a revised application. Discussion: Despite the negative outcome, the repeated recognition of MS as a global public health burden is sending a powerful message to governments globally that a range of affordable and good quality medications need to be available to health systems and people affected by MS.

Clinical characteristics and use of disease modifying therapy in the nationwide Danish cohort of paediatric onset multiple sclerosis. Mult Scler Relat Disord 2019; 37:101431. [PMID: 31670210 DOI: 10.1016/j.msard.2019.101431] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2019] [Revised: 09/07/2019] [Accepted: 10/04/2019] [Indexed: 01/26/2023]
Abstract
BACKGROUND Several disease-modifying therapies (DMT) are being used in paediatric patients with multiple sclerosis (MS) despite the limited number of randomised controlled clinical trials leading to approved indication in children. OBJECTIVES The aim of this study was to describe clinical characteristics of the Danish population of paediatric onset MS, and the patterns of DMT utilisation in patients who started treatment before the age of 18 years. METHODS We conducted a nationwide population-based cohort study, including 347 children with paediatric-onset MS (<18 years). Subjects were followed until their 25th birthday or end of follow-up. RESULTS Median age at onset and diagnosis was 15.8 years and 17.2, respectively. The majority of the children had monosymptomatic presentation. In total, 140 children received DMT before the age of 18. Most started treatment with a moderate-efficacy drug (90%) of which interferon-beta was the most used (80%). However, since oral treatments became available, these have increasingly been used. During follow-up, 108 children switched or discontinued DMT. Fingolimod was prescribed more frequently than natalizumab as escalation therapy. CONCLUSION We present that use of DMT in POMS varies over the observed period concurrently with the availability of disease modifying drugs with progressive use of oral and high-efficacy therapies.

Abstract
The last two decades witnessed significant advances in the treatment of acquired demyelinating disorders: thirteen new agents have been approved for the treatment of multiple sclerosis in adults by the European Medicines Agency and US Food and Drug Administration in the last twenty years. Although the long-term efficacy and safety profiles of some new drugs are still being assessed in paediatric MS, clinicians may have to use them in the management of paediatric onset MS resistant to first-line medications, based on results obtained in adult-onset disease. This review summarizes the current approach to treatment in children with demyelinating syndromes. WHAT THIS PAPER ADDS: Serological markers affect management in paediatric demyelinating diseases. Antibodies against aquaporin-4 and myelin oligodendrocyte glycoprotein should be tested in children with acute demyelinating disease. New therapeutic agents currently in trial for pediatric disease should be used with close follow-up.
