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.

Clinical, radiological, therapeutic and prognostic differences between MOG-seropositive and MOG-seronegative pediatric acute disseminated encephalomyelitis patients: a retrospective cohort study. Front Neurosci 2023; 17:1128422. [PMID: 37274199 PMCID: PMC10235790 DOI: 10.3389/fnins.2023.1128422] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Accepted: 04/25/2023] [Indexed: 06/06/2023] Open
Abstract
Objective This study aimed to compare the clinical, radiological, therapeutic, and prognostic differences between pediatric patients showing acute disseminated encephalomyelitis (ADEM) with and without myelin oligodendrocyte glycoprotein (MOG) antibodies. Methods We retrospectively collected all available data of children diagnosed with ADEM and tested for serum MOG antibodies at the Children's Hospital of Chongqing Medical University from January 2017 to May 2021. Results A total of 62 patients were included in our cohort, of which 35 were MOG-seropositive and 27 were MOG-seronegative. MOG-seropositive ADEM children presented with significantly lower rates of seizures (P = 0.038) and cranial nerve (III-XII) palsy (P = 0.003). Isolated leukocytosis in the blood was more common in ADEM children with MOG antibodies (P < 0.001). The two groups showed no significant differences in the distributions and extent of the MRI lesions as well as the appearance of typical/atypical magnetic resonance imaging (MRI) features. MOG-seropositive children were more likely to relapse (P = 0.017) despite having slower oral prednisolone tapering after acute treatments (P = 0.028). In scoring performed on the basis of two neurological function scoring systems, MOG-seropositive children showed milder neurological disability status at onset (P = 0.017 and 0.025, respectively) but showed no difference during follow-up. Conclusion In summary, the differences in the clinical manifestations and auxiliary examination findings for MOG-seropositive and MOG-seronegative ADEM children lacked significance and specificity, making early identification difficult. MOG-seropositive children were more likely to relapse and showed slower steroid tapering. Moreover, MOG-seronegative children tended to have more severe neurological impairments at onset with no difference during follow-up.

Front Immunol 2023; 13:1113406. [PMID: 36685590 PMCID: PMC9849793 DOI: 10.3389/fimmu.2022.1113406] [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: 12/01/2022] [Accepted: 12/15/2022] [Indexed: 01/07/2023] Open
Abstract
Neuromyelitis optica spectrum disorder (NMOSD), a severe demyelinating disease, is rare among children. Plasma exchange (PE) is widely used as a salvage therapy for severe and corticosteroid-unresponsive patients with NMOSD. Presently, there are limited studies on the safety and efficacy of PE in children with NMOSD. Herein, we report the case of six children with NMOSD who received PE along with the outcomes and adverse events. All six children (female, age at onset 4 years 9 months-13 years 2 months) were AQP4-IgG positive and received standard PE using the COM.TEC Cell Separator. The interval between NMOSD onset and PE was 29 days (range 10-98). Only one patient (P3) who received PE 10 days after acute exacerbations exhibited clinical improvement. Her left visual acuity increased from 0.06 to 0.6 (spectacle-corrected visual acuity was 1.0) and her EDSS score decreased from 4 to 3 points. The other five patients had no clinical improvement and no EDSS scores changes after PE. Adverse events included rashes (P1, P3), acute non-occlusive thrombosis of the internal jugular vein (P1), and thrombocytopenia (P2). In conclusion, the timing of PE initiation as a rescue therapy for severe and corticosteroid-unresponsive pediatric AQP4-IgG positive NMOSD may be crucial to treatment efficacy, and early initiation of PE may be associated with a better outcome. Furthermore, PE has the potential risk for clinically significant adverse effects that should be considered before initiating the therapy and should be weighed against potential benefits.

Spectrum of pediatric acquired demyelinating syndromes (PADS) of the central nervous system in a tropical developing country: A 10-year retrospective study. J Clin Neurosci 2022; 104:74-81. [PMID: 35981463 DOI: 10.1016/j.jocn.2022.08.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2021] [Revised: 06/30/2022] [Accepted: 08/07/2022] [Indexed: 11/21/2022]
Abstract
BACKGROUND Epidemiological data on the pediatric acquired demyelinating syndromes (PADS) in the Philippines has not been described previously in the literature. There may be geographic differences in frequencies of PADS where true disease burden is not known or underestimated in resource-limited settings due to lack of case recognition and/or diagnostic facilities. The purpose of this study was to determine the frequencies and clinical characteristics of the different subtypes of PADS at our institution and compare these with those in published literature. METHODS We conducted a retrospective cross-sectional study of children diagnosed with PADS who were admitted at the Philippine General Hospital from January 2009 to December 2018. Charts of these patients were reviewed to determine frequencies, clinical profile, diagnostic findings and outcomes. RESULTS A total of 77 patients were identified with PADS using the appropriate diagnostic criteria. The frequencies of the PADS subtypes were the following: transverse myelitis (n = 21; 27.3 %); acute disseminated encephalomyelitis (n = 20, 26.0 %); multiple sclerosis (n = 17, 22.1 %); optic neuritis (n = 13, 16.9 %); clinically isolated syndrome (n = 4, 5.2 %); and neuromyelitis optica spectrum disorder (n = 2, 2.6 %). Overall, the mean age at initial event and at diagnosis were 10.6 ± 4.6 years. Female:male ratio was 1.02:1. On admission, the majority of patients had motor paralysis (n = 49, 63.6 %) while several patients manifested with sensory deficits (n = 31, 40.3 %), visual changes (n = 26, 33.8 %) and brainstem involvement (n = 20, 26.0 %). Nearly all patients had evidence of lesions in magnetic resonance imaging (n = 72, 93.5 %) located in spinal cord (n = 25; 32.5 %), cerebral white matter (n = 24; 31.2 %), and optic nerve (n = 12, 15.6 %). Among patients who underwent cerebrospinal fluid analysis (n = 34), 7 patients had abnormal findings (20.6 %). The most utilized treatment regimens during admission were intravenous methylprednisolone (n = 53, 68.8 %) and oral prednisone (n = 43, 55.8 %). The majority had partial recovery (n = 56, 72.7 %) and 16 experienced full recovery (20.8 %) at discharge. Five patients died (6.5 %). CONCLUSIONS Our study provided the first comprehensive summary on the clinical features of children with PADS admitted in a Philippine tertiary hospital with limited resources. Our study highlights the value of using clinical diagnostic criteria in improving case recognition especially in low-and middle-income countries. Regional disparities in disease burden warrant international registries with wider geographic representation in order to come up with diagnostic and management guidelines suitable for various levels of care.

Abstract
PURPOSE OF REVIEW This article reviews the clinical presentation, diagnostic evaluation, treatment, and prognosis of the most common monophasic and relapsing acquired demyelinating disorders presenting in childhood. RECENT FINDINGS Our understanding of neuroimmune disorders of the central nervous system is rapidly expanding. Several clinical and paraclinical factors help to inform the diagnosis and ultimately the suspicion for a monophasic versus relapsing course, including the age of the patient (prepubertal versus postpubertal), presence or absence of clinical encephalopathy, identification of serum autoantibodies (eg, myelin oligodendrocyte glycoprotein [MOG] and aquaporin-4), presence of intrathecally unique oligoclonal bands, and location/extent of radiologic abnormalities. Collaborative international research efforts have facilitated understanding of the safety and efficacy of currently available immunotherapies in children with acquired demyelinating disorders, particularly multiple sclerosis. SUMMARY Although many of the demyelinating disorders presented in this article can affect children and adults across the age spectrum, the clinical and radiologic phenotypes, treatment considerations, and long-term prognoses are often distinct in children.

Abstract
BACKGROUND Dietary changes impact human physiology and immune function and have potential as therapeutic strategies. OBJECTIVE Assess the tolerability of a ketogenic diet (KD) in patients with relapsing multiple sclerosis (MS) and define the impact on laboratory and clinical outcome metrics. METHODS Sixty-five subjects with relapsing MS enrolled into a 6-month prospective, intention-to-treat KD intervention. Adherence was monitored with daily urine ketone testing. At baseline, fatigue, depression and quality of life (QoL) scores were obtained in addition to fasting adipokines and MS-related clinical outcome metrics. Baseline metrics were repeated at 3 and/or 6 months on-diet. RESULTS Eighty-three percent of participants adhered to the KD for the study duration. Subjects exhibited significant reductions in fat mass and showed a nearly 50% decline in self-reported fatigue and depression scores. MS QoL physical health (67±16 vs 79±12, p<0.001) and mental health (71±17 vs 82±11, p<0.001) composite scores increased on-diet. Significant improvements were noted in Expanded Disability Status Scale scores (2.3±0.9 vs 1.9±1.1, p<0.001), 6-minute walk (1631±302 vs 1733±330 ft, p<0.001) and Nine-Hole Peg Test (21.5±3.6 vs 20.3±3.7 s, p<0.001). Serum leptin was lower (25.5±15.7 vs 14.0±11.7 ng/mL, p<0.001) and adiponectin was higher (11.4±7.8 vs 13.5±8.4 µg/mL, p=0.002) on the KD. CONCLUSION KDs are safe and tolerable over a 6-month study period and yield improvements in body composition, fatigue, depression, QoL, neurological disability and adipose-related inflammation in persons living with relapsing MS. TRIAL REGISTRATION INFORMATION Registered on ClinicalTrials.gov under registration number NCT03718247, posted on 24 October 2018. First patient enrolment date: 1 November 2018.

Abstract
INTRODUCTION Tumefactive demyelination (TD) can be a challenging scenario for clinicians due to difficulties distinguishing it from other conditions, such as neoplasm or infection; or with managing the consequences of acute lesions, and then deciding upon the most appropriate longer term treatment strategy. AREAS COVERED The authors review the literature regarding TD covering its clinic-radiological features, association with multiple sclerosis (MS), and its differential diagnosis with other neuroinflammatory and non-inflammatory mimicking disorders with an emphasis on atypical forms of demyelination including acute disseminated encephalomyelitis (ADEM), MOG antibody-associated demyelination (MOGAD) and neuromyelitis spectrum disorders (NMOSD). We also review the latest in the acute and long-term treatment of TD. EXPERT OPINION It is important that the underlying cause of TD be determined whenever possible to guide the management approach which differs between different demyelinating and other inflammatory conditions. Improved neuroimaging and advances in serum and CSF biomarkers should one day allow early and accurate diagnosis of TD leading to better outcomes for patients.

Abstract
Recently, the problem of demyelinating diseases in children is still very acute. This occurs, on the one hand, by high access and specificity of diagnostic methods and, on the other hand - by high morbidity of children different neuroinfectious diseases which can lead to demyelinating diseases. This literature review presents the currently available information on the autoantibodies and neurospecific protein role in the development of multiple sclerosis and acute disseminative encephalitis in children. The authors also describe their experience of complex etiopatogenic therapy and cytoflavin use that helps to reduce frequency and expression of demyelinating process and endothelium dysfunction in case of active herpesvirus infection.

Abstract
The relevance of the study of demyelinating diseases is due to their increasing frequency in children, clarification of the role of infectious agents in their genesis, as well as the possibility of transformation of disseminated encephalomyelitis into multiple sclerosis. The literature review presents the currently available information on the causes of the development of demyelinating diseases, biomarkers of disseminated encephalomyelitis and multiple sclerosis, the causes of an unfavorable course and possible laboratory parameters indicating the transition from one disease to another, which can be used as prognostic factors. The authors also noted the experience of the authors on the importance of adequate etiopathogenetic therapy in changing the nature of the course of the disease, in particular, when confirming the relationship between the frequency of exacerbations of ADEM and MS with the activation of herpesvirus infections, courses of specific antiviral therapy are effective, as well as pathogenetic therapy aimed at correcting endothelial dysfunction using the drug cytoflavin.

Abstract
BACKGROUND Post-Infectious Neurological Syndromes (PINS) are heterogeneous neurological disorders with post or para-infectious onset. PINS diagnosis is complex, mainly related to the absence of any recognized guidelines and a univocal definition. AIM OF THE STUDY To elaborate a diagnostic guide for PINS. MATERIALS AND METHODS We retrospectively analysed patients younger than 14 years old admitted to Bambino Gesù Children's Hospital in Rome for PINS from December 2005 to March 2018. Scientific literature using PubMed as research platform was analysed: the key words "Post-Infectious Neurological Syndromes" were used. RESULTS A polysymptomatic presentation occurred in a percentage of 88% of the children. Motor signs and visual disturbances the most observed symptoms/signs were the most detached, followed by fever, speech disturbances, sleepiness, headache and bradipsychism. Blood investigations are compatible with inflammation, as a prodromal illnesses was documented in most cases. Normal cerebral spinal fluid (CSF) characteristics has been found in the majority of the study population. Magnetic resonance imaging (MRI) was positive for demyelinating lesions. Antibiotics, acyclovir and steroids have been given as treatment. DISCUSSION We suggest diagnostic criteria for diagnosis of PINS, considering the following parameters: neurological symptoms, timing of disease onset, blood and CSF laboratory tests, MRI imaging. CONCLUSIONS We propose criteria to guide clinician to diagnose PINS as definitive, probable or possible. Further studies are required to validate diagnostic criteria.

Abstract
AbstractAcute disseminated encephalomyelitis (ADEM) is an inflammatory demyelinating disease of the central nervous system which occurs predominantly in the pediatric population. Acute treatment is high-dose intravenous glucocorticoids. Alternative treatment is usually intravenous immune globulin and/or plasma exchange. Fulminant ADEM is rare in children. Only a few cases of cyclophosphamide use in refractory ADEM have been reported. Here, we report a case of a 12-year-old girl with fulminant ADEM who was comatose and improved dramatically after cyclophosphamide administration. Cyclophosphamide treatment should be considered as a therapy in children with fulminant ADEM nonresponsive to standard therapies.

Abstract
Multiple sclerosis (MS) is a chronic autoimmune disease affecting the central nervous system (CNS) which can lead to severe disability. Several diseases can mimic the clinical manifestations of MS. This can often lead to a prolonged period that involves numerous tests and investigations before a definitive diagnosis is reached. As well as the possibility of misdiagnosis. Molecular biomarkers can play a unique role in this regard. Molecular biomarkers offer a unique view into the CNS disorders. They help us understand the pathophysiology of disease as well as guiding our diagnostic, therapeutic, and prognostic approaches in CNS disorders. This review highlights the most prominent molecular biomarkers found in the literature with respect to MS and its related disorders. Based on numerous recent clinical and experimental studies, we demonstrate that several molecular biomarkers could very well aid us in differentiating MS from its related disorders. The implications of this work will hopefully serve clinicians and researchers alike, who regularly deal with MS and its related disorders.

Acute Disseminated Encephalomyelitis: An Unusual Presentation of Human Immunodeficiency Virus Infection. Case Rep Infect Dis 2020; 2020:1020274. [PMID: 32566331 PMCID: PMC7294351 DOI: 10.1155/2020/1020274] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Revised: 03/23/2020] [Accepted: 05/21/2020] [Indexed: 11/17/2022] Open
Abstract
Background Acute disseminated encephalomyelitis (ADEM) is a rare inflammatory and demyelinating disorder of the central nervous system, with a distinct tendency to a perivenous localization of pathological changes. Children are the most affected population and frequently presented after exanthematous viral infections or vaccination. Due to the rarity of this disease, the annual incidence rate in the population is not precisely known. Case Presentation. Here, we present a 28-year-old male HIV-1 positive patient with an acute confusional state, a diminished alert status characterized by somnolence, hypoprosexia, and complex visual hallucinations. Neuroimages reported white matter demyelinating lesions, mainly affecting the semioval centers, the frontal lobe, and the left parietal lobe; hypointense on T1-weighted images, hyperintense on T2-weighted images and fluid-attenuated inversion recovery weighted images, DWI with restricted diffusion, and a parietal ring-enhancing lesion after IV gadolinium administration. Discussion. In HIV positive patients, the demyelinating disorders have a broader clinical spectrum that could be explained by the immunosuppressed state of the patients, the evolution of the disease, the use of medications, the opportunistic infections, and the environment. Due to this highly variable clinical spectrum, ADEM is a significant challenge for the physicians in HIV positive patients, causing a delay in the diagnosis and treatment. Conclusion We suggest that ADEM should be considered among the differential diagnosis in HIV-infected patients with focal or multifocal neurological symptoms, particularly in encephalopathies with multifocal central nervous system involvement without severe immunosuppression.

Abstract
Multiple sclerosis (MS) is an autoimmune inflammatory disease affecting the central nervous system leading to demyelination. MS in the pediatric population is rare, but has been shown to lead to significant disability over the duration of the disease. As we have learned more about pediatric MS, there has been a development of improved diagnostic criteria leading to earlier diagnosis, earlier initiation of disease-modifying therapies (DMT), and an increasing number of DMT used in the treatment of pediatric MS. Over time, treatment with DMT has trended towards the initiation of higher efficacy treatment at time of diagnosis to help prevent further disease progression and accrual of disability over time, and there is evidence in current literature that supports this change in treatment patterns. In this review, we discuss the current knowledge in diagnosis, treatment, and clinical outcomes in pediatric MS.

Abstract
PURPOSE OF REVIEW The purpose of this review is to provide an update on advances in the understanding of pediatric demyelinating optic neuritis. RECENT FINDINGS In the past decade, the disease phenotypes for demyelinating syndromes in children have been more clearly defined. Pediatric optic neuritis may present as a clinically isolated syndrome or in the setting of underlying neurologic disease. In addition to optic neuritis associated with multiple sclerosis or neuromyelitis optica, recent work has identified antibodies to the myelin oligodendrocyte glycoprotein (MOG IgG) as a unique demyelinating cause with distinct features regarding treatment and prognosis. The disease phenotypes for demyelinating pediatric optic neuritis have expanded. Treatment strategies vary and are not universally effective for each cause of demyelinating disease. Accurately distinguishing among these unique clinical syndromes is therefore critical for initiation of appropriate treatment to prevent disability, to maximize visual outcomes, and to provide insight into long-term prognosis.

Consistent control of disease activity with fingolimod versus IFN β-1a in paediatric-onset multiple sclerosis: further insights from PARADIG MS. J Neurol Neurosurg Psychiatry 2020; 91:58-66. [PMID: 31467033 PMCID: PMC6952840 DOI: 10.1136/jnnp-2019-321124] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2019] [Revised: 08/09/2019] [Accepted: 08/12/2019] [Indexed: 01/27/2023]
Abstract
BACKGROUND In PARADIGMS, a double-blind phase III trial in 215 paediatric patients with multiple sclerosis (MS) (10 to <18 years), fingolimod administered for up to 2 years significantly reduced the annualised relapse rate (ARR) and rate of new/newly enlarged T2 (n/neT2) lesions compared with interferon (IFN) β-1a. OBJECTIVES To investigate (1) differences between treatment groups across subpopulations (treatment-naïve, younger/prepubertal patients); (2) disability progression. METHODS ARRs at 10, 11 and 12 years were estimated based on predefined modelling extrapolations. Changes in Expanded Disability Status Scale (EDSS), and in 3 month (3M) and 6 month (6M) confirmed disability progression (CDP) were evaluated post hoc. RESULTS In the treatment-naïve subpopulation, fingolimod reduced ARR and n/neT2 lesions by 85.8% and 53.4%, respectively versus INF β-1a (both p<0.001), compared with 81.9% and 52.6% in the overall population. Model-based ARR reductions in younger patients (≤12 years) were 91.9%-94.6%. Twice as many IFN β-1a-treated than fingolimod-treated patients had worse EDSS scores at study end (20.6% vs 10.5%, p=0.043). Risk reductions in 3M-CDP and 6M-CDP were 77.2% (p=0.007) and 80.2% (p=0.040), respectively. CONCLUSIONS Fingolimod in paediatric MS was associated with consistent control of disease activity versus IFN β-1a (including treatment-naïve and younger patients) and resulted in less disability progression for up to 2 years.

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.

A retrospective cohort study of plasma exchange in central nervous system demyelinating events in children. Mult Scler Relat Disord 2019; 35:50-54. [PMID: 31319355 DOI: 10.1016/j.msard.2019.07.004] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2019] [Revised: 06/18/2019] [Accepted: 07/07/2019] [Indexed: 01/04/2023]
Abstract
BACKGROUND Plasma exchange (PLEX) may improve recovery of acute central nervous system (CNS) demyelinating events related to multiple sclerosis (MS), neuromyelitis optica spectrum disorder (NMOSD), transverse myelitis (TM), acute disseminated encephalomyelitis (ADEM), and MOG-antibody associated demyelination (MOG) if recovery with pulse steroids (PS) is incomplete. Although there is a single randomized controlled trial in adults, there are limited case series in children. We aimed to describe the effectiveness and safety of PLEX in children with acute events of MS, NMOSD, TM, ADEM, and MOG with limited improvement after PS. METHODS This was a retrospective cohort study of children with acute CNS demyelinating events seen at a single tertiary referral center who received PLEX as a second- or third-line therapy between 2006 and 2018. Through chart review of clinical notes, presence of clinical improvement by physician assessment was recorded pre- and post-PS and pre- and post-PLEX. Expanded Disability Status Scale (EDSS) scores were collected pre- and post-PLEX. We evaluated the number who improved clinically with PLEX and compared pre- and post-PLEX EDSS with Wilcoxon matched pairs signed-rank test. RESULTS 26 patients followed at the Pediatric MS Center at the University of California, San Francisco received PLEX for acute events of MS (n = 15), NMOSD (n = 7), MOG (n = 2), TM (n = 1), and ADEM (n = 1). At time of PLEX initiation, median age was 13.5 years (range 3-17) and median time between the acute event onset and PLEX initiation was 22 days (range 3-94). 14 of 24 patients had documented clinical improvement after PS. Of those who improved during PS (n = 14), 13 had additional improvement after PLEX. Of those with no improvement after PS (n = 10), 8 improved after PLEX. 16 of 26 patients had pre- and post-PLEX EDSS scores available. Median pre-PLEX EDSS score was 4.0 (range 3.0-8.0), and median post-PLEX EDSS score was 3.75 (range 0-8.0) (p = 0.062). 5 patients had improved EDSS scores by 1 or more points. Adverse events during PLEX included hypotension (n = 3), nausea (n = 2), headache (n = 2), hypocalcemia (n = 2), hypofibrinogenemia (n = 2), thrombocytopenia (n = 1), spinal cord hemorrhage (n = 1), acute non-occlusive thrombosis of internal jugular vein (n = 1), occlusion of the central line (n = 1), edema of the neck (n = 1), and gastrointestinal discomfort (n = 1). CONCLUSIONS PLEX is an overall well-tolerated second-line treatment option for pediatric patients with severe acute CNS demyelinating events with limited response to PS.

Mult Scler Relat Disord 2019; 34:150-157. [PMID: 31295724 DOI: 10.1016/j.msard.2019.06.031] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2019] [Revised: 06/25/2019] [Accepted: 06/26/2019] [Indexed: 12/14/2022]
Abstract
BACKGROUND Although relatively rare among pediatric patients, acquired demyelinating syndromes of the central nervous system (ADS) is a potentially disabling condition that warrants hospitalization and long-term follow-up. As such, a better understanding of the epidemiology and hospital utilization for this condition could provide critical information for health care planning and resource allocation. OBJECTIVE To evaluate the trends of hospital utilization and resource use associated with pediatric ADS in the US. METHOD We conducted a serial cross-sectional trend analysis with complex sampling and weighting using nationally representative hospital discharge records, from the Kids´ Inpatient Database (KID), Healthcare Cost and Utilization Project (HCUP), Agency for Healthcare Research and Quality coded with International Classification of Diseases (Healthcare Cost and Utilization Project (HCUP) 2018), Ninth Revision (ICD-9-CM) for the years 2003, 2006, 2009, and 2012. We also conducted a cross-sectional study for the KID2016 dataset coded with ICD10-CM to estimate the pediatric ADS-related hospital utilization for the year. EXCLUDING TRANSFERRING DISCHARGES: we evaluated the discharge records for those aged 0 to 19 years diagnosed with any of ADS of central nervous systems including multiple sclerosis (MS), neuromyelitis optica spectrum disorder (NMOSD), acute disseminated encephalomyelitis (ADEM), optic neuritis (ON), transverse myelitis (TM) and demyelinating disease not specified (DDNS). For the trend analysis, we used variance-weighted regression and Poisson regression for the annual hospitalization rate, total hospital charges and hospital days associated with the ADS hospitalizations for the year 2003 to 2012. RESULTS We estimated a total of 1,292 ADS-related hospitalizations (95%CI: 1127-1,458) in 2003, 2104 hospitalizations (95%CI: 1823-2385) in 2006, 2851 hospitalizations (95%CI: 2499-3203) in 2009, and 3501 hospitalizations (95%CI: 3058-3945) in 2012 among those aged 19 years or younger with diagnoses of ADS. There was an increase in the proportion of the inpatient hospital cost attributed to ADS from 0.06% in 2003 to 0.20% in 2012. The annual hospitalization rates relative to pediatric ADS were 1.59/100,000 (95%CI: 1.51-1.68) in 2003 and 4.21/100,000 (95%CI: 4.07-4.35) in 2012. In the cross-sectional analysis for the year 2016 coded by ICD10-CM, the number of pediatric ADS related hospitalizations were 4,568, constituting 0.30% of the total pediatric hospitalization cost. The annual hospitalization rate for the year 2016 was estimated to be 5.51/100,000. CONCLUSION Hospital utilization by pediatric patients with ADS increased during the period 2003 through 2012. The cross-sectional analysis for the year 2016 indicated that the trend could be ongoing, although the direct comparison was not feasible due to the changes in the coding system of the dataset from ICD9-CM to ICD10-CM. Although relatively rare, pediatric ADS warrant long-term follow-ups and hospitalizations, impacting the developmental trajectory of the affected children and the lives of their family members. Th potentially increasing trend of pediatric ADS hospital utilization should be acknowledged when allocating and planning future resources and supporting programs.

Abstract
AIM To investigate whether local or national guidelines are used in treating neuroinflammatory conditions in children and if there is a perceived need for more guidelines and forums of cooperation. METHODS A web-based questionnaire sent to all university hospitals in the Nordic countries (n = 21) between March and July 2015. RESULTS All 21 centres replied to the survey. Markers of neuronal or glial damage and markers of inflammation were used at varying rates. Neuronal antibodies were used at all sites except two. Only three hospitals collaborated with their laboratories in developing new assays for biomarkers. Although most centres used some form of guideline for neuroinflammatory conditions, no single disease had a guideline prevalence over 60%. For some diagnoses, access to guidelines was as low as 10%. Standardised follow-up programs were lacking in 50-95%. A clear majority of the centres perceived a need for more guidelines. Also, forums of cooperation were few. However, there was a great interest in developing paediatric neuroinflammatory guidelines and to create platforms for further consensus work and discussion. CONCLUSION There is a need for developing treatment guidelines within the field of paediatric neuroinflammation to aid in clinical decision-making, and to establish forums of cooperation.

Abstract
Interest in autoimmune encephalitis has been growing since the discovery of various autoimmune antibodies, such as N‐methyl D‐aspartate receptors antibody and leucine‐rich glioma‐inactivated 1 antibody. However, in contrast to autoimmune encephalitis associated with dysregulated adaptive immunity in the brain, the question of whether innate immunity‐mediated autoinflammatory diseases exist in the brain has drawn much attention. Herein, we report a patient with microglia‐dominant acute autoinflammatory encephalitis successfully treated with anakinra, an including interleukin‐1 receptor blocker. In comparison to systemic autoinflammatory disease, we term this encephalitis cerebral autoinflammatory disease. Cerebral autoinflammatory disease could suggest new conceptual approaches to patients previously diagnosed with an unspecified encephalitis.

Abstract
BACKGROUND Treatment of patients younger than 18 years of age with multiple sclerosis has not been adequately examined in randomized trials. We compared fingolimod with interferon beta-1a in this population. METHODS In this phase 3 trial, we randomly assigned patients 10 to 17 years of age with relapsing multiple sclerosis in a 1:1 ratio to receive oral fingolimod at a dose of 0.5 mg per day (0.25 mg per day for patients with a body weight of ≤40 kg) or intramuscular interferon beta-1a at a dose of 30 μg per week for up to 2 years. The primary end point was the annualized relapse rate. RESULTS Of a total of 215 patients, 107 were assigned to fingolimod and 108 to interferon beta-1a. The mean age of the patients was 15.3 years. Among all patients, there was a mean of 2.4 relapses during the preceding 2 years. The adjusted annualized relapse rate was 0.12 with fingolimod and 0.67 with interferon beta-1a (absolute difference, 0.55 relapses; relative difference, 82%; P<0.001). The key secondary end point of the annualized rate of new or newly enlarged lesions on T2-weighted magnetic resonance imaging (MRI) was 4.39 with fingolimod and 9.27 with interferon beta-1a (absolute difference, 4.88 lesions; relative difference, 53%; P<0.001). Adverse events, excluding relapses of multiple sclerosis, occurred in 88.8% of patients who received fingolimod and 95.3% of those who received interferon beta-1a. Serious adverse events occurred in 18 patients (16.8%) in the fingolimod group and included seizures (in 4 patients), infection (in 4 patients), and leukopenia (in 2 patients). Serious adverse events occurred in 7 patients (6.5%) in the interferon beta-1a group and included infection (in 2 patients) and supraventricular tachycardia (in 1 patient). CONCLUSIONS Among pediatric patients with relapsing multiple sclerosis, fingolimod was associated with a lower rate of relapse and less accumulation of lesions on MRI over a 2-year period than interferon beta-1a but was associated with a higher rate of serious adverse events. Longer studies are required to determine the durability and safety of fingolimod in pediatric multiple sclerosis. (Funded by Novartis Pharma; PARADIGMS ClinicalTrials.gov number, NCT01892722 .).

Abstract
Multiple sclerosis is among the most serious inflammatory demyelinating diseases (IDD). Interleukin-23A (IL23A) regulates and coordinates the activities of immune cells by interacting with its receptor IL23R and plays key roles in the pathogenesis of immune inflammatory diseases. IDD, deemed to be a kind of autoimmune diseases, may involve IL23A in the pathogenesis. The aim of this work was to validate the hypothesized involvement of IL-23A and its receptor in IDD. We sequenced the IL-23A and IL-23R genes for 206 Chinese Han IDD patients and evaluated SNPs within or near those genes. The serum levels of IL23A in IDD participants were analyzed using ELISA. The statistical analyses were conducted using Chi-Square Tests as implemented in SPSS (version 19.0). The Hardy-Weinberg equilibrium test of the population was carried out using online software OEGE. Three variants rs2066808, rs2371494, rs11575248 in IL-23A gene and one variant rs1884444 in IL-23R gene were demonstrated to be associated with the risk of MS or other IDD diseases, and the expression level of serum IL-23A in the MS patients was also altered. We conclude that variants in IL-23A and IL-23R genes were associated with the risk of MS or other IDD diseases.

Abstract
BACKGROUND Pediatric multiple sclerosis is an increasingly recognized and studied disorder that accounts for 3% to 10% of all patients with multiple sclerosis. The risk for pediatric multiple sclerosis is thought to reflect a complex interplay between environmental and genetic risk factors. MAIN FINDINGS Environmental exposures, including sunlight (ultraviolet radiation, vitamin D levels), infections (Epstein-Barr virus), passive smoking, and obesity, have been identified as potential risk factors in youth. Genetic predisposition contributes to the risk of multiple sclerosis, and the major histocompatibility complex on chromosome 6 makes the single largest contribution to susceptibility to multiple sclerosis. With the use of large-scale genome-wide association studies, other non-major histocompatibility complex alleles have been identified as independent risk factors for the disease. The bridge between environment and genes likely lies in the study of epigenetic processes, which are environmentally-influenced mechanisms through which gene expression may be modified. CONCLUSIONS This article will review these topics to provide a framework for discussion of a comprehensive approach to counseling and ultimately treating the pediatric patient with multiple sclerosis.

Abstract
Optic neuritis is rare in children in comparison to adults, but accounts for approximately 25% of pediatric acute demyelinating syndromes. Features of pediatric optic neuritis that differ from adults include a higher rate of bilaterality, poor visual acuity on presentation, and papillitis. Diagnostic work-up includes brain magnetic resonance imaging, lumbar puncture, and blood tests to exclude infectious and inflammatory disorders. Pediatric optic neuritis may occur following infection or vaccination, or in association with a systemic demyelinating process such as acute disseminated encephalomyelitis, neuromyelitis optica, or multiple sclerosis. Treatment is controversial, but most practitioners administer corticosteroids. Most children with optic neuritis experience full visual recovery. The recently launched Pediatric Optic Neuritis Prospective Data Collection Study (PON1) aims to provide estimates of visual acuity outcome and assess the potential to recruit for a future pediatric optic neuritis treatment trial.

Abstract
BACKGROUND Acute disseminated encephalomyelitis (ADEM) is an immune-mediated, inflammatory acquired demyelinating syndrome predominantly affecting the white matter of the central nervous system. METHODS We describe a three-year-old boy whose clinical presentation was suspicious for ADEM but whose initial imaging abnormalities were confined to the deep gray matter (without evidence of white matter involvement). His clinical course was fluctuating and repeat imaging one week after presentation demonstrated interval development of characteristic white matter lesions. RESULTS Treatment with adjunctive intravenous immunoglobulin and high-dose corticosteroids resulted in significant clinical improvement. CONCLUSIONS Isolated deep gray matter involvement can precede the appearance of white matter abnormalities of ADEM, suggesting that repeat imaging is indicated in individuals whose findings are clinically suspicious for ADEM but who lack characteristic imaging findings.

Abstract
AbstractBackground: Recurrent ataxia is encountered infrequently in clinical pediatric neurology practise and presents with diagnostic challenges. It is caused by several disorders. Our aims were to describe the epidemiology and clinical features in children with recurrent ataxia. Materials and Methods: A retrospective review was undertaken in 185 children with chronic ataxia, who presented during 1991 to 2008. Several databases were searched to ensure optimum ascertainment. Patients with brain tumors or isolated disorders of the peripheral nerves or vestibular system were excluded. Results: Recurrent ataxia was reported in 21 patients. Their age range was between 6 and 32.75 years (males=12). The crude period prevalence rate for the 18-year study period was 7.44/100,000. Eight patients had episodic ataxia and seven had inflammatory and metabolic disorders. In the rest the etiology was unknown. Many patients presented with ataxia, dizziness, and vertigo. The frequency and duration of the ataxic episodes varied from several per day to one every few months. Other clinical features included developmental delay and seizures. Neuroimaging in episodic ataxia was normal and abnormal in inflammatory or metabolic disorders. Acetazolamide provided symptomatic relief in patients with episodic ataxia, while steroids were beneficial in patients with an inflammatory etiology. One child with a metabolic disorder died. Conclusions: Recurrent ataxia is an uncommon presentation in children and mortality is rare. Genetic, metabolic, and inflammatory disorders should be considered in these patients. Neuroimaging is essential. Acetazolamide in selected patients provides good symptomatic relief.
