Ghezzi A. Old and New Strategies in the Treatment of Pediatric Multiple Sclerosis: A Personal View for a New Treatment Approach. Neurol Ther 2024:10.1007/s40120-024-00633-6.

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
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.

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
Obesity has been suggested as an environmental risk factor for multiple sclerosis (MS) and may negatively effect the progression of the disease. The aim of this study is to determine any correlation between overweight/obesity and the clinical and neuroradiological features at the onset of pediatric onset multiple sclerosis (POMS). Were included patients referred to the POMS Unit of the Bambino Gesù Children's Hospital between June 2012 and June 2021. The diagnosis of MS with an onset of less than 18 years was required. For all included subjects, we considered for the analysis the following data at the onset of symptoms: general data (age, sex, functional system compromised by neurological signs, weight and height), brain and spinal magnetic resonance imaging (MRI), cerebrospinal fluid exams. We identified 55 pediatric cases of POMS and divided them into two groups according to the body mass index (BMI): 60% were healthy weight (HW) and 40% were overweight/obese (OW/O). OW/O patients experienced a two-year age difference in disease onset compared to the HW patients (12.7 ± 3.8 years vs. 14.6 ± 4.1 years; p < 0.05). Onset of polyfocal symptoms was seen more frequently in OW/O patients than in HW (72.7% vs. 21.2%; p < 0.05). The pyramidal functions were involved more frequently in the OW/O group than in the HW group (50% vs. 25%; p < 0.005). Black holes were detected more frequently in OW/O patients in onset MRI scans compared to the HW group (50% vs. 15.5%; p < 0.05). Our findings suggest that being overweight/obese affects the risk of developing MS at an earlier age and is associated with an unfavorable clinical-radiological features at onset. Weight control can be considered as a preventive/therapeutic treatment.

Pretreatment Neurofilament Light Chain Serum Levels, Early Disease Severity, and Treatment Response in Pediatric Multiple Sclerosis. Neurology 2023; 101:e1873-e1883. [PMID: 37748882 PMCID: PMC10663003 DOI: 10.1212/wnl.0000000000207791] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Accepted: 07/12/2023] [Indexed: 09/27/2023] Open
Abstract
BACKGROUND AND OBJECTIVES High disease activity and frequent therapy failure in pediatric multiple sclerosis (MS) make prognostic biomarkers urgently needed. We investigated whether serum neurofilament light chain (sNfL) levels in treatment-naive pediatric patients with MS are associated with early disease severity and indicate treatment outcomes. METHODS A retrospective cohort study of patients seen in the Göttingen Center for MS in Childhood and Adolescence, Germany. Inclusion criteria were MS diagnosis according to the McDonald criteria, MS onset <18 years, and available pretreatment serum sample. sNfL levels were analyzed using a single-molecule array assay. Associations with clinical and MRI evidence of disease severity at sampling were evaluated using the Spearman correlations and nonparametric tests for group comparisons. Correlations between pretreatment sNfL and annualized relapse and new T2 lesion rate on first-line therapy, and odd ratios for switch to high-efficacy therapy were assessed. RESULTS A total of 178 patients (116 women [65%]) with a mean sampling age of 14.3 years were included in the study. Pretreatment sNfL levels were above the ≥90th percentile reported for healthy controls in 80% of patients (median 21.1 pg/mL) and correlated negatively with age, but no correlation was seen with sex, oligoclonal band status, or body mass index. High pretreatment sNfL levels correlated significantly with a high number of preceding relapses, a shorter first interattack interval, a high T2 lesion count, and recent gadolinium-enhancing lesions. Of interest, sNfL levels reflected more strongly MRI activity rather than clinical activity. Pretreatment sNfL levels also correlated significantly with the relapse rate and occurrence of new/enlarging T2 lesions while on first-line injectable therapy. Odds of future therapy escalation increased from 0.14 for sNfL below 7.5 pg/mL to 6.38 for sNfL above 15 pg/mL. In patients with a recent relapse, higher sNfL levels were associated with poorer recovery 3 months after attack. DISCUSSION The results of this study have 3 important implications: First, pretreatment sNfL levels are a valuable biomarker for underlying disease activity in pediatric patients with MS. Second, pretreatment sNfL levels in pediatric patients with MS have a predictive value for the response to first-line therapy and the necessity of future therapy escalation. Third, high sNfL levels during a relapse are associated with poor recovery in this age group.

Abstract
BACKGROUND Pediatric forms of multiple sclerosis are more active than those in adults. Yet, the effectiveness of different therapeutic approaches is not well studied in this population. Our objective was to compare the effectiveness of the early use of high efficacy therapies (HETs) with the effectiveness of moderate efficacy therapies (METs) in children with MS. METHODS This observational study included patients diagnosed with pediatric MS, at 4 hospital centers in France, during a 10-year period. METs included: interferon β-1a, glatiramer acetate, dimethyl fumarate, teriflunomide; HETs included: fingolimod, natalizumab, ocrelizumab, alemtuzumab. The primary endpoint was the occurrence of a new relapse, the secondary endpoint was EDSS worsening. RESULTS Sixty-four patients were included in the analysis (80% women; mean age 15.5 years, 81% treated with MET) with a median follow-up of 22.5 months. At baseline, 52 patients were on MET (interferon β-1a, glatiramer acetate, dimethyl fumarate, teriflunomide) and 12 patients were on HET (natalizumab, ocrelizumab). The cumulative probability of being relapse-free at 6.5 years was 23.3% on MET, vs 90.9% on HET (p = 0.013). The cumulative probability of no EDSS worsening did not differ between the 2 groups. CONCLUSION Patients starting with METs had much higher clinical disease activity than those starting early with HETs. Rapid initiation of more aggressive treatment may allow better disease control; however, the data on EDSS worsening are not conclusive.

Abstract
Multiple sclerosis (MS) is a debilitating autoimmune condition caused by demyelination, neurodegeneration and persistent inflammation of the central nervous system. Pediatric multiple sclerosis (PMS) is a relatively rare form of the disease that affects a significant number of individuals with MS. Environmental exposures, such as viral infections and smoking, can interact with MS-associated human leukocyte antigens (HLA) risk alleles and influence the immune response. Upregulation of immune response results in the disruption of immune balance leading to cascade of inflammatory events. It has also been established that gut microbiome dysbiosis poses a higher risk for pro-inflammation, and it is essentially argued to be the greatest environmental risk factor for MS. Dysbiosis can cause an unusual response from the adaptive immune system and significantly contribute to the development of disease in the host by activating pro-inflammatory pathways that cause immune-mediated disorders such as PMS, rendering the body more vulnerable to foreign attacks due to a weakened immune response. All these dynamic interactions between biological, environmental and genetic factors based on epigenetic study has further revealed that upregulation or downregulation of some genes/enzyme in the central nervous system white matter of MS patients produces a less stable form of myelin basic protein and ultimately leads to the loss of immune tolerance. The diagnostic criteria and treatment options for PMS are constantly evolving, making it crucial to have a better understanding of the disease burden on a global and regional scale. The findings from this review will aid in deepening the understanding of the interplay between genetic and environmental risk factors, as well as the role of the gut microbiome in the development of pediatric multiple sclerosis. As a result, healthcare professionals will be kept abreast of the early diagnostic criteria, accurately delineating other conditions that can mimic pediatric MS and to provide comprehensive care to individuals with PMS based on the knowledge gained from this research.

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) represents a chronic immune-mediated neurodegenerative disease of the central nervous system that generally debuts around the age of 20-30 years. Still, in recent years, MS has been increasingly recognized among the pediatric population, being characterized by several peculiar features compared to adult-onset disease. Unfortunately, the etiology and disease mechanisms are poorly understood, rendering the already limited MS treatment options with uncertain efficacy and safety in pediatric patients. Thus, this review aims to shed some light on the progress in MS therapeutic strategies specifically addressed to children and adolescents. In this regard, the present paper briefly discusses the etiology, risk factors, comorbidities, and diagnosis possibilities for pediatric-onset MS (POMS), further moving to a detailed presentation of current treatment strategies, recent clinical trials, and emerging alternatives. Particularly, promising care solutions are indicated, including new treatment formulations, stem cell therapies, and cognitive training methods.

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.

Abstract
The appearance of new foci on MRI, the increase in neurological deficits, including the appearance of cognitive disorders and disturbances in the level of consciousness in patients with multiple sclerosis during the «washing period» when transferring from natalizumab (NZ) to another drug, may be due to both progressive multifocal leukoencephalopathy (PML) and exacerbation of the disease in the absence of therapy. Discontinuation of NS is fraught not only with a resumption, but with an increase in disease activity, the development of an immune reconstitution inflammatory syndrome (IRIS) due to the opening of the blood-brain barrier. Often, the processes of differential diagnosis of IRIS and natalizumab-associated PML are complex and require the use of additional methods of examination and monitoring of the dynamics of the patient's condition. However, the severity of the condition and the severity of the consequences caused by incorrect therapeutic tactics significantly reduce the time for diagnosis and require an immediate decision. The difficulties of differential diagnosis of IRIS and PML are reflected in the clinical case.

Abstract
BACKGROUND Paediatric-onset multiple sclerosis (POMS) is increasing worldwide and represents approximately 5% of all MS cases. Although this patient group has similar characteristics to the adult group, it is important for this patient group to receive effective treatment due to the early onset of cognitive involvement, higher lesion burden, and secondary progression at an earlier age than adults. In this study, we aimed to evaluate the factors that cause treatment change in POMS patients. MATERIAL AND METHOD Adult patients with a first MS attack at age 18 years or younger who were followed up with the diagnosis of MS at the Clinical Neuroimmunology and Demyelinating Diseases outpatient clinic of Cerrahpaşa Medical School between 1987 and 2020 were included in our study. Patient files were reviewed retrospectively, and demographic and clinical characteristics, imaging, first attack characteristics, and treatment change were noted. We included 269 patients with a definite diagnosis of MS in the study, and these patients were evaluated in two groups: negative for treatment change and positive for treatment change. RESULTS Multifocal involvement was detected more frequently in the group with treatment change (p = 0,049). Cerebellar involvement as a first attack symptom was more common in male patients (p = 0,023) The age at first MS attack was found to be younger (p = 0,006), and the disease duration was longer in the positive for treatment change group (p = 0,003). Spinal cord involvement was more common in the positive for treatment change group (p = 0,016). Abnormal VEP findings were observed more frequently in the group without treatment change (p = 0.018). In multivariant analysis, spinal cord involvement, younger age at first attack, and abnormal VEP findings in the group without treatment change were found to be significant. Among the reasons for treatment change, the most common reason was radiological and clinical progression. CONCLUSION The higher inflammatory load in POMS patients compared with adults necessitates early initiation of treatment in this group and timely treatment change to prevent disability. Furthermore, this patient group should be followed closely and receive effective treatment.

Abstract
The course of pediatric-onset multiple sclerosis and adult multiple sclerosis shows some clinical differences. The rate of having a second attack after the first clinical event is 80% in children and around 45% in adults but the time to the second event is similar in all age groups. The pediatric group usually has a more aggressive onset than adults. On the other hand, a higher rate of complete recovery is observed in pediatric-onset multiple sclerosis after the first clinical event compared to the adult group. Despite a highly active initial disease course, pediatric-onset multiple sclerosis patients show a slower increase in disability than patients with adult-onset disease. This is thought to be due to greater remyelination capacity and plasticity of the developing brain. The management of pediatric-onset multiple sclerosis includes safety issues as well as effective disease control. In the pediatric-onset multiple sclerosis group, similar to adult multiple sclerosis, injectable treatments have been used for many years with reasonable efficacy and safety. Since 2011, oral treatments and then infusion treatments have been approved and used effectively in adult multiple sclerosis and have gradually entered clinical use in the pediatric-onset multiple sclerosis group. However, clinical trials are fewer, smaller, and include shorter follow-up due to the much lower prevalence of pediatric-onset multiple sclerosis than adult multiple sclerosis. This is particularly important in the era of recent disease-modifying treatments. This review of the literature presents existing data on the safety and efficacy of fingolimod, pointing to a relatively favorable profile.

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
INTRODUCTION Fingolimod was the first oral disease-modifying treatment approved for relapsing-remitting multiple sclerosis (MS) that serves as a sphingosine-1-phosphate receptor (S1PR) agonist. The efficacy is primarily mediated by S1PR subtype 1 activation, leading to agonist-induced down-modulation of receptor expression and further functional antagonism, blocking the egression of auto-aggressive lymphocytes from the lymph nodes in the peripheral compartment. The role of S1P signaling in the regulation of other pathways in human organisms through different S1PR subtypes has received much attention due to its immune-modulatory function and its significance for the regeneration of the central nervous system (CNS). The more selective second-generation S1PR modulators have improved safety and tolerability profiles. AREAS COVERED This review has been carried out based on current data on S1PR modulators, emphasizing the benefits of recent advances in this emergent class of immunomodulatory treatment for MS. EXPERT OPINION Ongoing clinical research suggests that S1PR modulators represent an alternative to first-line therapies in selected cases of MS. A better understanding of the relevance of selective S1PR pathways and the ambition to optimize selective modulation has improved the safety and tolerability of S1PR modulators in MS therapy and opened new perspectives for the treatment of other diseases.

Abstract
BACKGROUND Natalizumab (NAT) has a strong impact on disease activity of aggressive pediatric multiple sclerosis (MS), with no difference in safety profile compared to adult MS. However, available data are limited by short follow-up. Our aim was to report long-term follow-up data (up to 11 years) of a large Italian pediatric MS cohort treated with NAT. MATERIALS AND METHODS We retrospectively collected data of pediatric MS patients treated with NAT included in a previous study and prospectively followed in Italian MS centers. We compared disease activity pre, during, and post-NAT and we performed survival analyses of time to evidence of disease activity (EDA) during NAT, time to reach EDA post-NAT, and time to NAT discontinuation. RESULTS Ninety-two patients were included from 19 MS centers in Italy. At NAT initiation, cohort's characteristics were as follows: 55 females; 14.7 ± 2.4 (mean ± SD) years of age; 34 naïve to disease modifying therapies; 1-year pre-NAT annualized relapse rate (ARR): 2.2 ± 1.2; EDSS (median [IQR]): 2.5 [2.0-3.0]; gadolinium-enhancing lesions: 2 [1-5]; 41 JCV positives. During NAT treatment (61.9 ± 35.2 mean infusions), ARR lowered to 0.08 ± 0.23 (p < 0.001), EDSS score to 1.5 [1.0-2.5] at last infusion (p < 0.001), and 51% patients had EDA (21% after 6 months of rebaseline). No serious adverse events were reported. Forty-nine patients discontinued NAT, mainly due to PML concern; the majority (29/49) had disease reactivation in the subsequent 12 months, of which three with a clinical rebound. CONCLUSION NAT treatment maintains its high efficacy for a long time in pediatric MS patients, with no new safety issues.

Solmaz I, Acar Ozen P, Parlak S, Tuncer A, Anlar B. Newer disease modifying treatments in pediatric onset multiple sclerosis: Experience from a single center. Eur J Paediatr Neurol 2022; 39:110-115. [PMID: 35777190 DOI: 10.1016/j.ejpn.2022.06.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 04/18/2022] [Accepted: 06/20/2022] [Indexed: 10/17/2022]
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.

Natalizumab therapy in patients with pediatric-onset multiple sclerosis in Greece: clinical and immunological insights of time-long administration and future directions-a single-center retrospective observational study. Naunyn Schmiedebergs Arch Pharmacol 2022; 395:933-943.

Abstract
Pediatric-onset multiple sclerosis (MS, POMS) accounts for 3-5% of all MS cases and is characterized by a highly inflammatory profile, often warranting treatment with high-efficacy agents. Our aim is to present real-world data of a series of 18 Hellenic POMS patients treated with natalizumab (NTZ) either as adolescents or as adults, after high disease activity has efficiently subsided. Clinical and imaging/laboratory data from 18 POMS patients who have received at least one NTZ infusion were selected in this single-center retrospective observational study. Human leukocyte antigen (HLA) genotyping was performed with standard low-resolution sequence-specific oligonucleotide techniques. Eighteen patients with a mean age of disease onset of 15.3 ± 2.4 years were treated with NTZ with a mean of 51.7 ± 46.4 infusions, 6 as adolescents and 12 as adults. 22.2% were treatment naïve. At the end of the observational period, patients of both groups remained relapse-free, with no radiological activity and significantly reduced disability accumulation. No evidence of disease activity (NEDA)-3 status was achieved in 66.7% of all patients, 58.3% in the adult-treated, and 83.3% in the adolescent-treated POMS patients. NTZ was generally well tolerated. Only 5 adverse events were observed, in 3 patients who were carriers of the HLA-DRB1*15 (HLA-DRB1*15/HLA-DRB1*11 and HLA-DRB1*15/HLA-DRB1*13 genotypes), 1 homozygous for the HLA-DRB1*03 allele and 1 heterozygous for HLA-DRB1*04 and HLA-DRB1*16 alleles. NTZ is highly efficacious and mostly safe for POMS patients with high disease activity in all age groups. The role of immunogenetics in personalized patient evaluation and treatment needs to be further investigated.

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
Approximately 40% of young-onset multiple sclerosis (MS) patients experience breakthrough disease, which carries a high risk for long-term disability, and requires using therapies beyond traditional first-line agents. Despite the increasing use of newer disease-modifying treatments (DMTs) in this population, data are not available to guide the need for escalating DMTs and there is a scarcity of data on the effects of natalizumab in children and young adults with active disease. We performed a retrospective analysis of the rate of No Evidence of Disease Activity (NEDA), tolerability, and safety of natalizumab in a multi-center cohort of 36 children and young adults with highly active MS. All patients had active disease and initiated treatment with natalizumab. The primary endpoint was the rate of achieving NEDA-3 status, within two years of natalizumab treatment. To examine a possible effect of age on the outcome of treatment, outcomes were also analyzed by pre-pubertal (n = 13 children aged 9-13 years) and pubertal subgroups (n = 23 young adolescents aged 14-20 years). The NEDA-3 status of the pre-pubertal group was 92% in the first and second year and in the pubertal group - 96% in the first year and 92% in the second year. Natalizumab reduced the number and volume of brain lesions in both pre-pubertal and pubertal groups. Treatment was well-tolerated, only 8 patients (22.2%) had adverse events during the 2-year study period. Our analysis shows that natalizumab is effective and well-tolerated in pre-pubertal and pubertal MS patients.

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 The manifestation of multiple sclerosis (MS) in childhood and adolescence occurs in 3%-5% of all MS cases. However, the immunomodulatory and symptomatic treatment options in this population group are still limited. OBJECTIVE We aimed to elucidate the prescription frequency of medications used in pediatric patients with multiple sclerosis (PwMS) compared with the general population, considering the entire spectrum of medications prescribed. METHODS Based on nationwide outpatient drug prescription data and statutory health insurance (SHI) physicians' claims data from 2018, we conducted a population-based cross-sectional study in Germany. Children and adolescents aged ⩽17 years (n = 11,381,939) diagnosed with MS (n = 613), and a matched (age, sex, and health insurance sector) control group (n = 6130) were included. The prescription prevalence was measured as the proportion of MS patients with ⩾1 prescription. RESULTS Of the 613 pediatric PwMS with a median age of 16 years, 403 (65.7%) were female. For 15 out of the 18 different active agents analyzed, PwMS had a significantly higher prescription prevalence than the control group (Fisher's exact test: p ⩽ 0.037). The most frequently prescribed drugs in PwMS were ibuprofen (28.4%; anti-inflammatory drug), cholecalciferol (23.0%; vitamin D3), and interferon beta-1a (21.5%; disease-modifying drug, DMD). The proportions of DMD prescriptions and antibiotic prescriptions were higher among PwMS aged 15-17 years than among those ⩽14 years (DMD: 43.4% vs 34.2%, p = 0.05; antibiotic: 34.1% vs 24.8%, p = 0.031). In contrast, younger PwMS were more likely to receive a prescription for anti-inflammatory/anti-rheumatic drugs (36.6% vs 26.5%, p = 0.02). CONCLUSION Our study analyzing real-world medication data showed that interferon beta, anti-inflammatory drugs, and vitamins play an essential role in the treatment of pediatric PwMS. Future research should evaluate longitudinal treatment patterns of pediatric PwMS, paying particular attention to the time of diagnosis, time of first DMD initiation, and therapy switches.

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
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
Objectives To compare the real-world effectiveness of newer disease-modifying therapies (DMTs) vs injectables in children with relapsing-remitting multiple sclerosis (RRMS). Methods In this retrospective, multicenter study, from the UK Childhood Inflammatory Demyelination Network, we identified children with RRMS receiving DMTs from January 2012 to December 2018. Clinical and paraclinical data were retrieved from the medical records. Annualized relapse rates (ARRs) before and on treatment, time to relapse, time to new MRI lesions, and change in Expanded Disability Status Scale (EDSS) score were calculated. Results Of 103 children treated with DMTs, followed up for 3.8 years, relapses on treatment were recorded in 53/89 (59.5%) on injectables vs 8/54 (15%) on newer DMTs. The ARR was reduced from 1.9 to 1.1 on injectables (p < 0.001) vs 1.6 to 0.3 on newer DMTs (p = 0.002). New MRI lesions occurred in 77/89 (86.5%) of patients on injectables vs 26/54 (47%) on newer DMTs (p = 0.0001). Children on newer DMTs showed longer time to relapse, time to switch treatment, and time to new radiologic activity than patients on injectables (log-rank p < 0.01). After adjustment for potential confounders, multivariable analysis showed that injectables were associated with 12-fold increased risk of clinical relapse (adjusted hazard ratio [HR] = 12.12, 95% CI = 1.64–89.87, p = 0.015) and a 2-fold increased risk of new radiologic activity (adjusted HR = 2.78, 95% CI = 1.08–7.13, p = 0.034) compared with newer DMTs. At 2 years from treatment initiation, 38/103 (37%) patients had MRI activity in the absence of clinical relapses. The EDSS score did not change during the follow-up, and only 2 patients had cognitive impairment. Conclusion Newer DMTs were associated with a lower risk of clinical and radiologic relapses in patients compared with injectables. Our study adds weight to the argument for an imminent shift in practice toward the use of newer, more efficacious DMTs in the first instance. Classification of Evidence This study provides Class IV evidence that newer DMTs (oral or infusions) are superior to injectables (interferon beta/glatiramer acetate) in reducing both clinical relapses and radiologic activity in children with RRMS.

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
Pediatric-onset multiple sclerosis (POMS) accounts for approximately 2-10% of all cases of multiple sclerosis (MS) and is associated with higher levels of disease activity than adult-onset MS, including higher rates of clinical relapse and a greater incidence of new T2 lesions on magnetic resonance imaging (MRI). First-line therapy for POMS usually includes interferon β or glatiramer acetate; however, there is limited evidence from randomized trials regarding the safety and efficacy of these disease-modifying drugs in pediatric patients. Fingolimod represents a second-line therapy option for relapsing-remitting MS in pediatric patients. Here, we report the case of a 14-year-old girl with a diagnosis of POMS who started interferon β-1a as first-line therapy and then switched to fingolimod after 12 months due to radiologic progression and clinical relapse. The patient subsequently experienced clinical stability and showed minimal radiologic activity on follow-up MRI. Our case demonstrates the real-world clinical effectiveness and safety of fingolimod in pediatric MS and is in line with the results of previous randomized and observational studies.

Abstract
The field of acquired CNS neuroimmune demyelination in children is transforming. Progress in assay development, refinement of diagnostic criteria, increased biological insights provided by advanced neuroimaging techniques, and high-level evidence for the therapeutic efficacy of biological agents are redefining diagnosis and care. Three distinct neuroimmune conditions-multiple sclerosis, myelin-oligodendrocyte glycoprotein antibody-associated disease (MOGAD), and aquaporin-4 antibody-associated neuromyelitis optica spectrum disorder (AQP4-NMOSD)-can now be distinguished, with evidence from humans and animal models supporting distinct pathobiological disease mechanisms. The development of highly effective therapies for adult-onset multiple sclerosis and AQP4-NMOSD that suppress relapse rate by more than 90% has motivated advocacy for trials in children. However, doing clinical trials is challenging because of the rarity of these conditions in the paediatric age group, necessitating new approaches to trial design, including age-based trajectory modelling based on phase 3 studies in adults. Despite these limitations, the future for children and adolescents living with multiple sclerosis, MOGAD, or AQP4-NMOSD is far brighter than in years past, and will be brighter still if successful therapies to promote remyelination, enhance neuroprotection, and remediate cognitive deficits can be further accelerated.

Abstract
Background: Pediatric multiple sclerosis (MS) is rare: only 1.5-5% of MS cases are diagnosed before 18 years of age, and data on disease-modifying therapies (DMTs) for pediatric MS are limited. The CONNECTED study assessed the long-term safety and efficacy of treatment with delayed-release dimethyl fumarate (DMF), an oral MS DMT, in pediatric patients with MS. Methods: CONNECTED is the 96-week extension to FOCUS, a 24-week phase 2 study of patients aged 13-17 years; participants received DMF 240 mg twice daily. Endpoints included (primary) incidence of adverse events (AEs), serious AEs, and DMF discontinuations due to an AE, and (secondary) T2 hyperintense lesion incidence by magnetic resonance imaging and annualized relapse rate (ARR). Results: Twenty participants [median (range) age, 17 (14-18) years; 65% female] who completed FOCUS enrolled into CONNECTED; 17 (85%) completed CONNECTED. Eighteen participants (90%) experienced AEs: the most frequent was flushing (25%). None experienced infections or fever related to low lymphocyte counts. Three participants experienced four serious AEs; none led to DMF discontinuation. Twelve of 17 participants (71%) had no new/newly enlarged T2 lesions from weeks 16-24, two (12%) had one, and one each (6%) had two, three, or five or more lesions [median (range), 0 (0-6)]. Over the full 120-week treatment period, ARR was 0.2, an 84.5% relative reduction (n = 20; 95% confidence interval: 66.8-92.8; p < 0.0001) vs. the year before DMF initiation. Conclusions: The long-term safety and efficacy observed in CONNECTED was consistent with adults, suggesting pediatric and adolescent patients with MS might benefit from DMF treatment.

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
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
The natural history of multiple sclerosis (MS) is highly heterogeneous. A subgroup of patients has what might be termed aggressive MS. These patients may have frequent, severe relapses with incomplete recovery and are at risk of developing greater and permanent disability at the earlier stages of the disease. Their therapeutic window of opportunity may be narrow, and while it is generally considered that they will benefit from starting early with a highly efficacious treatment, a unified definition of aggressive MS does not exist and data on its treatment are largely lacking. Based on discussions at an international focused workshop sponsored by the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), we review our current knowledge about treatment of individuals with aggressive MS. We analyse the available evidence, identify gaps in knowledge and suggest future research needed to fill those gaps. A companion paper details the difficulties in developing a consensus about what defines aggressive MS.

Abstract
OBJECTIVE To assess real-world effectiveness of initial treatment with newer compared to injectable disease-modifying therapies (DMTs) on disease activity in pediatric multiple sclerosis (MS) and clinically isolated syndrome (CIS). METHODS This is a cohort study of children with MS/CIS followed at 12 clinics in the US Network of Pediatric MS Centers, who received initial therapy with newer (fingolimod, dimethyl fumarate, teriflunomide, natalizumab, rituximab, ocrelizumab) or injectable (interferon-β, glatiramer acetate) DMTs. Propensity scores (PSs) were computed, including preidentified confounders. Relapse rate while on initial DMT was modeled with negative binomial regression, adjusted for PS-quintile. Time to new/enlarging T2-hyperintense and gadolinium-enhancing lesions on brain magnetic resonance imaging were modeled with midpoint survival analyses, adjusted for PS-quintile. RESULTS A total of 741 children began therapy before 18 years, 197 with newer and 544 with injectable DMTs. Those started on newer DMTs were older (15.2 vs injectable 14.4 years, p = 0.001) and less likely to have a monofocal presentation. In PS-quintile-adjusted analysis, those on newer DMTs had a lower relapse rate than those on injectables (rate ratio = 0.45, 95% confidence interval (CI) = 0.29-0.70, p < 0.001; rate difference = 0.27, 95% CI = 0.14-0.40, p = 0.004). One would need to treat with newer rather than injectable DMTs for 3.7 person-years to prevent 1 relapse. Those started on newer DMTs had a lower rate of new/enlarging T2 (hazard ratio [HR] = 0.51, 95% CI = 0.36-0.72, p < 0.001) and gadolinium-enhancing lesions (HR = 0.38, 95% CI = 0.23-0.63, p < 0.001) than those on injectables. INTERPRETATION Initial treatment of pediatric MS/CIS with newer DMTs led to better disease activity control compared to injectables, supporting greater effectiveness of newer therapies. Long-term safety data for newer DMTs are required. ANN NEUROL 2020 ANN NEUROL 2020;88:42-55.

Serum neurofilament light chain is a useful biomarker in pediatric multiple sclerosis. NEUROLOGY-NEUROIMMUNOLOGY & NEUROINFLAMMATION 2020; 7:7/4/e749. [PMID: 32404429 PMCID: PMC7238898 DOI: 10.1212/nxi.0000000000000749] [Citation(s) in RCA: 35] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/20/2019] [Accepted: 04/09/2020] [Indexed: 12/13/2022]
Abstract
Objective To investigate serum neurofilament light chain (sNfL) as a potential biomarker for disease activity and treatment response in pediatric patients with multiple sclerosis (MS). Methods In this retrospective cohort study, sNfL levels were measured in a pediatric MS cohort (n = 55, follow-up 12–105 months) and in a non-neurologic pediatric control cohort (n = 301) using a high-sensitivity single-molecule array assay. Association of sNfL levels and treatment and clinical and MRI parameters were calculated. Results Untreated patients had higher sNfL levels than controls (median 19.0 vs 4.6 pg/mL; CI [4.732, 6.911]), p < 0.001). sNfL levels were significantly associated with MRI activity (+9.1% per contrast-enhancing lesion, CI [1.045, 1.138], p < 0.001; +0.6% per T2-weighted lesion, CI [1.001, 1.010], p = 0.015). Higher values were associated with a relapse <90 days ago (+51.1%; CI [1.184, 1.929], p < 0.001) and a higher Expanded Disability Status Scale score (CI [1.001, 1.240], p = 0.048). In patients treated with interferon beta-1a/b (n = 27), sNfL levels declined from 14.7 to 7.9 pg/mL after 6 ± 2 months (CI [0.339, 0.603], p < 0.001). Patients with insufficient control of clinical or MRI disease activity under treatment with interferon beta-1a/b or glatiramer acetate who switched to fingolimod (n = 18) showed a reduction of sNfL levels from 16.5 to 10.0 pg/mL 6 ± 2 months after switch (CI [0.481, 0.701], p < 0.001). Conclusions sNfL is a useful biomarker for monitoring disease activity and treatment response in pediatric MS. It is most likely helpful to predict disease severity and to guide treatment decisions in patients with pediatric MS. This study provides Class III evidence that sNfL levels are associated with disease activity in pediatric MS.

Effect of fingolimod on MRI outcomes in patients with paediatric-onset multiple sclerosis: results from the phase 3 PARADIG MS study. J Neurol Neurosurg Psychiatry 2020; 91:483-492. [PMID: 32132224 PMCID: PMC7231437 DOI: 10.1136/jnnp-2019-322138] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2019] [Revised: 01/30/2020] [Accepted: 02/03/2020] [Indexed: 01/08/2023]
Abstract
OBJECTIVE PARADIGMS demonstrated superior efficacy and comparable safety of fingolimod versus interferon β-1a (IFN β-1a) in paediatric-onset multiple sclerosis (PoMS). This study aimed to report all predefined MRI outcomes from this study. METHODS Patients with multiple sclerosis (MS) (aged 10-<18 years) were randomised to once-daily oral fingolimod (n=107) or once-weekly intramuscular IFN β-1a (n=108) in this flexible duration study. MRI was performed at baseline and every 6 months for up to 2 years or end of the study (EOS) in case of early treatment discontinuation/completion. Key MRI endpoints included the annualised rate of formation of new/newly enlarging T2 lesions, gadolinium-enhancing (Gd+) T1 lesions, new T1 hypointense lesions and combined unique active (CUA) lesions (6 months onward), changes in T2 and Gd+ T1 lesion volumes and annualised rate of brain atrophy (ARBA). RESULTS Of the randomised patients, 107 each were treated with fingolimod and IFN β-1a for up to 2 years. Fingolimod reduced the annualised rate of formation of new/newly enlarging T2 lesions (52.6%, p<0.001), number of Gd+ T1 lesions per scan (66.0%, p<0.001), annualised rate of new T1 hypointense lesions (62.8%, p<0.001) and CUA lesions per scan (60.7%, p<0.001) versus IFN β-1a at EOS. The percent increases from baseline in T2 (18.4% vs 32.4%, p<0.001) and Gd+ T1 (-72.3% vs 4.9%, p=0.001) lesion volumes and ARBA (-0.48% vs -0.80%, p=0.014) were lower with fingolimod versus IFN β-1a, the latter partially due to accelerated atrophy in the IFN β-1a group. CONCLUSION Fingolimod significantly reduced MRI activity and ARBA for up to 2 years versus IFN β-1a in PoMS.

Abstract
We analyze the differential brain volume changes in highly active multiple sclerosis (HAMS) vs. non-HAMS patients during the disease onset. METHODS HAMS was defined as: a) patients with 1 relapse in the previous year and at least 1 T1 gadolinium-enhancing lesion or 9 or more T2 lesions while on therapy with other disease modifying treatment (DMD); or b) patients with 2 or more relapses in the previous year, whether on DMD or not. High-resolution T1 weighted MRI scans were acquired at onset and every 12 months for 2 years. Lesion load and brain volume measurements were determined. At onset, gray matter volume (GMV) and white matter volume (WMV) tissue volumes were calculated using the SIENAX. Longitudinal changes were estimated by using SIENA to calculate the percentage of brain volume loss. Differences between volumes per group at onset and at the end of the follow up were established. RESULTS 64 patients, mean age 38.4 years, 35 (57%) women were included. A total of 14 (21%) were classified as HAMS. At onset, HAMS patients showed lower GMV and WMV volume compared with non-HAMS patients (p = 0.003 and p = 0.01, respectively). During the follow up, HAMS patients showed a higher decrease in GM volume compared with non-HAMS patients (-0.61 vs. - 0.77, p < 0.001) independent from new lesion as well as relapse rate activity during follow up. CONCLUSION HAMS increased rates of GMV atrophy over 24 months compared to non-HAMS patients independent from relapse rate and new T2 lesions.

PEDIATRIC HEALTH MEDICINE AND THERAPEUTICS 2019; 10:141-146. [PMID: 31814792 PMCID: PMC6858833 DOI: 10.2147/phmt.s220817] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/02/2019] [Accepted: 09/16/2019] [Indexed: 11/23/2022]
Abstract
Pediatric-onset multiple sclerosis (POMS) is an immune-mediated, demyelinating, neurodegenerative disease that accounts for 3-5% of all multiple sclerosis (MS) cases. Although evidence suggests that it has similar risk factors and disease pathophysiology as adult-onset MS (AOMS), there are distinctive features in disease characteristics and patient demographics of POMS that require unique therapeutic development and treatment considerations. Gilenya® (Novartis International AG, Basel, Switzerland) (fingolimod) is a sphingosine-1-phosphate (S1P) receptor modulator that prevents lymphocytic outflow from peripheral lymph nodes. It has demonstrated efficacy in AOMS. In POMS, there have been three observational studies and one pivotal clinical trial evaluating the efficacy, safety, and tolerability of fingolimod. Currently, fingolimod is the only Food and Drug Administration and European Medicines Agency approved disease-modifying therapy to treat POMS. This review will critically evaluate the available evidence of fingolimod in the treatment of POMS in detail, as well as discussing its treatment implications.

Abstract
PURPOSE OF REVIEW To summarize recent developments in the classification, investigation and management of pediatric optic neuritis (PON). RECENT FINDINGS A recent surge in interest surrounding antibodies to myelin oligodendrocyte glycoprotein antibody (MOG-Ab) has instigated a paradigm shift in our assessment of children with PON. This serological marker is associated with a broad spectrum of demyelinating syndromes that are clinically and radiologically distinct from multiple sclerosis (MS) and aquaporin-4 antibody positive neuromyelitis optica spectrum disorder (AQP4+NMOSD). Optic neuritis is the most common presenting phenotype of MOG-Ab positive-associated disease (MOG+AD). MOG-Ab seropositivity is much more common in the pediatric population and it predicts a better prognosis than MS or AQP4+NMOSD, except in the subset that exhibit a recurrent phenotype. SUMMARY A better grasp of MOG+AD features and its natural history has facilitated more accurate risk stratification of children after a presenting episode of PON. Consequently, the initial investigation of PON has broadened to include serology, along with neuroimaging and cerebrospinal fluid analysis. Acute treatment of PON and chronic immunotherapy is also becoming better tailored to the suspected or confirmed diagnoses of MS, AQP4+NMOSD and MOG+AD.

Abstract
PURPOSE OF REVIEW With the recognition that pediatric-onset multiple sclerosis (POMS) is characterized by more prominent disease activity, earlier age at onset of disability milestones, and more prominent cognitive impairment compared with physical disability earlier in the disease course compared with adult-onset multiple sclerosis (AOMS), there has been increasing interest in identifying optimal and safe treatment approaches to achieve better disease control in this group. Injectable therapies have been traditionally used as first line in this population, although not formally approved. This review focuses on current treatment and monitoring approaches in POMS. RECENT FINDINGS In the past few years, and despite the paucity of FDA-approved medications for use in POMS, an increasing trend toward using newer disease-modifying therapies (DMTs) in this group is observed. However, escalation (as opposed to induction) remains the most frequent approach, and many children continue to be untreated before age 18, particularly before age 12. The only FDA- and EMA-approved disease-modifying therapy in POMS is fingolimod; however, dimethyl fumarate, teriflunomide, natalizumab, ocrelizumab, and alemtuzumab either have been evaluated in observational studies or are being currently investigated in formal randomized controlled trials for use in POMS and appear to be safe in this group. Autologous hematopoietic stem cell transplantation has also been evaluated in a small series. Clinical outcome measures and MS biomarkers have been poorly studied in POMS; however, the use of composite functional scores, neurofilament light chain, optical coherence tomography, and imaging findings is being increasingly investigated to improve early diagnosis and efficient monitoring of POMS. Off-label use of newer DMTs in POMS is increasing, and based on retrospective data, and phase 2 trials, this approach appears to be safe in children. Results from ongoing trials will help clarify the safety and efficacy of these therapies in the future. Fingolimod is the only FDA-approved medication for use in POMS. Outcome measures and biomarkers used in AOMS are being studied in POMS and are greatly needed to quantify treatment response in this group.

Abstract
Multiple sclerosis is a chronic immune-mediated demyelinating disease of the central nervous system. The diagnosis of multiple sclerosis in children, as in adults, requires evidence of dissemination of inflammatory activity in more than one location in the central nervous system (dissemination in space) and recurrent disease over time (dissemination in time). The identification of myelin oligodendrocyte glycoprotein antibodies (MOG-Ab) and aquaporin-A antibodies (AQP4-Ab), and the subsequent discovery of their pathogenic mechanisms, have led to a shift in the classification of relapsing demyelinating syndromes. This is reflected in the 2017 revised criteria for the diagnosis of multiple sclerosis, which emphasizes the exclusion of multiple sclerosis mimics and aims to enable earlier diagnosis and thus treatment initiation. The long-term efficacy of individual therapies initiated in children with multiple sclerosis is hard to evaluate, owing to the small numbers of patients who have the disease, the relatively high number of patients who switch therapy, and the need for long follow-up studies. Nevertheless, an improvement in prognosis with a globally reduced annual relapse rate in children with multiple sclerosis is now observed compared with the pretreatment era, indicating a possible long-term effect of therapies. Given the higher relapse rate in children compared with adults, and the impact multiple sclerosis has on cognition in the developing brain, there is a question whether rapid escalation or potent agents should be used in children, while the short- and long-term safety profiles of these drugs are being established. With the results of the first randomized controlled trial of fingolimod versus interferon-β1a in paediatric multiple sclerosis published in 2018 and several clinical trials underway, there is hope for further progress in the field of paediatric multiple sclerosis. WHAT THIS PAPER ADDS: Early and accurate diagnosis of multiple sclerosis is crucial. The discovery of antibody-mediated demyelination has changed the diagnosis and management of relapsing demyelination syndromes. Traditional escalation therapy is being challenged by induction therapy.

Abstract
Objective This phase I study investigated pharmacokinetic (PK) and pharmacodynamic (PD) profiles of natalizumab in pediatric patients with relapsing-remitting MS (RRMS). Methods Pediatric patients with RRMS who were prescribed natalizumab 300 mg IV every 4 weeks were enrolled. Blood samples were collected on days 1, 2, 8, 15, and 22 and at weeks 4, 8, 12, and 16 to estimate PK parameters; PD properties were evaluated by measuring α4-integrin saturation and lymphocyte counts over time. Natalizumab's safety profile was also evaluated. Results PK parameters were similar to those reported in adult patients; natalizumab concentrations peaked approximately 1 day after infusion in most of the participants (Cmax 142.9 μg/mL, AUClast 47389.4 hr*μg/mL), followed by a biphasic decline with a rapid distribution phase and a slow elimination phase, with a terminal half-life of 215.1 hours. In terms of PD, both time course and magnitude of α4-integrin saturation and increase in lymphocyte counts were similar to those observed in adults. During the 16-week study follow-up, 3 adverse events attributed to natalizumab were observed; no unexpected safety events occurred. Conclusions PK profile, α4-integrin saturation, lymphocyte counts, and safety observed in these pediatric patients are comparable to those reported in adults. Classification of evidence This study provides Class I evidence that natalizumab PK/PD parameters and safety profile are similar in adults and pediatric patients in the short term. Longer studies, also including a larger number of younger subjects (aged 10-12 years), are required to further inform about long-term PK and PD parameters in pediatric patients with MS.

Abstract
Pediatric-onset multiple sclerosis (MS) comprises 2-5% of MS cases, and is known to be associated with high disease activity and the accumulation of disability at an earlier age than their adult-onset counterparts. Appropriate therapy leading to disease control has the potential to alter the known trajectory of adverse long-term physical, cognitive, and psychosocial outcomes in this population. Thus, optimizing treatment for children and adolescents with MS is of paramount importance. The last decade has seen a growing number of disease-modifying therapies approved for relapsing MS in adults, and available agents now include oral, injectable, and infusion therapies. Recently, the development of randomized controlled MS trials in youth has led to the first agent approved by the US FDA for the treatment of pediatric MS-fingolimod. With this, we have entered a new era of knowledge and treatment in this population and ongoing pediatric trials are expected to further inform clinical management. With the emergence of highly effective therapies targeting the inflammatory component of the disease, there has been increased interest in identifying treatment strategies that instead target mechanisms such as remyelination/repair, neuroprotection, or rehabilitation. The potential role for such emerging therapies in the treatment of pediatric MS remains an important area of study. In this review, we discuss current evidence for MS therapies in children including the treatment of acute relapses, disease-modifying therapies, and symptomatic management. We will also discuss evidence for emerging therapies, including remyelinating and neuroprotective agents.

Abstract
OBJECTIVE To characterize the use and safety of newer disease-modifying therapies (DMTs) in children with multiple sclerosis (MS) and clinically isolated syndrome (CIS) treated under 18 years of age. METHODS This is a cohort study including children with MS or CIS followed at 12 outpatient practices participating in the US Network of Pediatric MS Centers. DMT use, including duration, dose, and side effects, was analyzed. Newer DMTs were defined as agents receiving Food and Drug Administration approval or with increased use in adult MS after 2005. RESULTS As of July 2017, 1,019 pediatric patients with MS (n = 748) or CIS (n = 271) were enrolled (65% female, mean onset 13.0 ± 3.9 years, mean follow-up 3.5 ± 3.1 years, median 1.6 visits per year). Of these, 78% (n = 587) with MS and 11% (n = 31) with CIS received DMT before 18 years of age. This consisted of at least one newer DMT in 42%, including dimethyl fumarate (n = 102), natalizumab (n = 101), rituximab (n = 57), fingolimod (n = 37), daclizumab (n = 5), and teriflunomide (n = 3). Among 17%, the initial DMT prescribed was a newer agent (36 dimethyl fumarate, 30 natalizumab, 22 rituximab, 14 fingolimod, 2 teriflunomide). Over the last 10 years, the use of newer agents has increased, particularly in those ≥12 years and to lesser extent in those <12 years. The short-term side effect profiles of newer DMTs did not differ from those reported in adults. CONCLUSION Newer DMTs are often used in pediatric MS, and have similar short-term safety, tolerability, and side effect profiles as in adults. These findings may help inform pediatric MS management.

Abstract
INTRODUCTION Although the frequency of pediatric-onset multiple sclerosis (POMS) has increased in recent decades, it is still highly uncommon, which creates a need for the involvement of more registries from various clinical centers. OBJECTIVE To characterize the demographic, clinical, and paraclinical features of Egyptian patients with POMS. PATIENTS AND METHODS A retrospective chart review study was undertaken on 237 Egyptian patients with demyelinating events which started before the age of 18 years who attended one of five tertiary referral centers in Cairo, Egypt. RESULTS Multiple sclerosis was diagnosed in 186 patients, 47 (25.27%) patients had disease onset before the age of 12 years; "early-onset pediatric multiple sclerosis (EOPMS)". The mean age of disease onset was (14.13±2.49 years), with a female:male ratio of 1.62:1, none of the enrolled patients had a primary progressive course (PPMS), whereas 10 patients (5.38%) had a secondary progressive form. Approximately two-thirds of the patients had monofocal disease onset, and less than 10% presented with encephalopathy; most of them had EOPMS. Motor weakness was the presenting symptom in half of the patients, whereas cerebellar presentation was detected in 34.95%, mainly in EOPMS. Seizures (not related to encephalopathy) were more frequent in those with EOPMS. Initial brain magnetic resonance images were positive in all patients, with detected atypical lesions in 29.03%, enhanced lesions in 35.48%, black holes in 13.98%, and infratentorial in 34.41%. Cervical cord involvement was found in 68.28%. More than two-thirds of the patients received either immunomodulatory or immunosuppressant (IS) treatment throughout their disease course, and about half of them received their treatment within the first year from symptoms onset, with a more favorable outcome, and patients with highly active disease received natalizumab, fingolimod, or other IS. CONCLUSION The results from this registry - the largest for MS in the Arab region to date - are comparable to other registries. Immunomodulatory therapies in POMS are well tolerated and efficacious and they can improve the long-term outcome in children.
