RESUMEN
BACKGROUND: Autoimmune encephalitis (AIE) is a group of inflammatory diseases characterized by the presence of antibodies against neuronal and glial antigens, leading to subacute psychiatric symptoms, memory complaints, and movement disorders. The patients are predominantly young, and delays in treatment are associated with worse prognosis. OBJECTIVE: With the support of the Brazilian Academy of Neurology (Academia Brasileira de Neurologia, ABN) and the Brazilian Society of Child Neurology (Sociedade Brasileira de Neurologia Infantil, SBNI), a consensus on the diagnosis and treatment of AIE in Brazil was developed using the Delphi method. METHODS: A total of 25 panelists, including adult and child neurologists, participated in the study. RESULTS: The panelists agreed that patients fulfilling criteria for possible AIE should be screened for antineuronal antibodies in the serum and cerebrospinal fluid (CSF) using the tissue-based assay (TBA) and cell-based assay (CBA) techniques. Children should also be screened for anti-myelin oligodendrocyte glucoprotein antibodies (anti-MOG). Treatment should be started within the first 4 weeks of symptoms. The first-line option is methylprednisolone plus intravenous immunoglobulin (IVIG) or plasmapheresis, the second-line includes rituximab and/or cyclophosphamide, while third-line treatment options are bortezomib and tocilizumab. Most seizures in AIE are symptomatic, and antiseizure medications may be weaned after the acute stage. In anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis, the panelists have agreed that oral immunosuppressant agents should not be used. Patients should be evaluated at the acute and postacute stages using functional and cognitive scales, such as the Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA), the Modified Rankin Scale (mRS), and the Clinical Assessment Scale in Autoimmune Encephalitis (CASE). CONCLUSION: The present study provides tangible evidence for the effective management of AIE patients within the Brazilian healthcare system.
ANTECEDENTES: Encefalites autoimunes (EAIs) são um grupo de doenças inflamatórias caracterizadas pela presença de anticorpos contra antígenos neuronais e gliais, que ocasionam sintomas psiquiátricos subagudos, queixas de memória e distúrbios anormais do movimento. A maioria dos pacientes é jovem, e o atraso no tratamento está associado a pior prognóstico. OBJETIVO: Com o apoio da Academia Brasileira de Neurologia (ABN) e da Sociedade Brasileira de Neurologia Infantil (SBNI), desenvolvemos um consenso sobre o diagnóstico e o tratamento da EAIs no Brasil utilizando a metodologia Delphi. MéTODOS: Um total de 25 especialistas, incluindo neurologistas e neurologistas infantis, foram convidados a participar. RESULTADOS: Os especialistas concordaram que os pacientes com critérios de possíveis EAIs devem ser submetidos ao rastreio de anticorpos antineuronais no soro e no líquido cefalorraquidiano (LCR) por meio das técnicas de ensaio baseado em tecidos (tissue-based assay, TBA, em inglês) e ensaio baseado em células (cell-based assay, CBA, em inglês). As crianças também devem ser submetidas ao rastreio de de anticorpo contra a glicoproteína da mielina de oligodendrócitos (anti-myelin oligodendrocyte glycoprotein, anti-MOG, em inglês). O tratamento deve ser iniciado dentro das primeiras 4 semanas dos sintomas, sendo as opções de primeira linha metilprednisolona combinada com imunoglobulina intravenosa (IGIV) ou plasmaférese. O tratamento de segunda linha inclui rituximabe e ciclofosfamida. Bortezomib e tocilizumab são opções de tratamento de terceira linha. A maioria das crises epilépticas nas EAIs são sintomáticas, e os fármacos anticrise podem ser desmamadas após a fase aguda. Em relação à encefalite antirreceptor de N-metil-D-aspartato (anti-N-methyl-D-aspartate receptor, anti-NMDAR, em inglês), os especialistas concordaram que agentes imunossupressores orais não devem ser usados. Os pacientes devem ser avaliados na fase aguda e pós-aguda mediante escalas funcionais e cognitivas, como Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Modified Rankin Scale (mRS), e Clinical Assessment Scale in Autoimmune Encephalitis (CASE). CONCLUSãO: Esta pesquisa oferece evidências tangíveis do manejo efetivo de pacientes com EAIs no sistema de saúde Brasileiro.

Neuromyelitis optica spectrum disorder (NMOSD) is a rare and severe inflammatory disorder of the central nervous system (CNS). It is strongly associated with anti-aquaporin 4 antibodies (AQP4-IgG), and it mainly affects young women from non-white ethnicities. However, â¼ 5 to 10% of all cases have onset during childhood. Children and adolescents share the same clinical, radiologic, and laboratory presentation as adults. Thus, the same NMOSD diagnostic criteria are also applied to pediatric-onset patients, but data on NMOSD in this population is still scarce. In seronegative pediatric patients, there is a high frequency of the antibody against myelin oligodendrocyte glycoprotein (MOG-IgG) indicating another disease group, but the clinical distinction between these two diseases may be challenging. Three drugs (eculizumab, satralizumab, and inebilizumab) have been recently approved for the treatment of adult patients with AQP4-IgG-positive NMOSD. Only satralizumab has recruited adolescents in one of the two pivotal clinical trials. Additional clinical trials in pediatric NMOSD are urgently required to evaluate the safety and efficacy of these drugs in this population.
O espectro da neuromielite óptica (ENMO) é uma rara e grave doença inflamatória do sistema nervoso central (SNC), fortemente associada ao anticorpo anti-aquaporina 4 (AQP4-IgG) e que afeta preferencialmente mulheres jovens de etnias não-caucasianas. No entanto, aproximadamente de 5 a 10% de todos os casos se iniciam na infância. Crianças e adolescentes compartilham as mesmas características clínicas, radiológicas e laboratoriais dos adultos. Além disso, o mesmo critério diagnóstico de ENMO é aplicado para pacientes com início na infância. No entanto, dados da população pediátrica são escassos. Em pacientes pediátricos soronegativos, existe uma alta frequência de positividade ao anticorpo contra a glicoproteína na mielina do oligodendrócito (MOG-IgG), indicando outra patologia; porém, a distinção clínica entre as duas doenças é desafiadora. Três medicações (eculizumabe, inebilizumabe e satralizumabe) foram recentemente aprovadas para pacientes adultos com AQP4-IgG. Apenas um dos ensaios pivotais do satralizumabe recrutou adolescentes. Novos ensaios clínicos em pacientes pediátricos com ENMO são necessários para avaliar a segurança e eficácia destas drogas nesta população.

BACKGROUND AND PURPOSE: Around 5% of all Neuromyelitis Optica Spectrum Disorders (NMOSD) cases start before 18 years of age. Clinical and radiological manifestations of AQP4-IgG positive NMOSD were revised in 2015, and the importance of neuroimaging in the diagnosis is well recognized. Neuroimaging findings in pediatric-onset NMOSD were scarcely described, and longitudinal evaluation of NMOSD lesions was only accessed in a few adult-onset cohorts. METHODS: This study evaluated brain, spinal cord, and optic nerve MRI of sixteen pediatric-onset AQP4-IgG positive NMOSD through a qualitative evaluation of lesion evolution. Lesions were classified as symptomatic or asymptomatic in acute or chronic phase (> 30 days from last attack) MRI. RESULTS: Seventy MRI scans and 54 subsequent exams were evaluated. Most NMOSD lesions (74.5%) reduced, remained stable, or developed atrophy/cavitation. New brain lesions or enlargement of existing brain lesions were found in two patients (12.5%) without any clinical symptom and in five patients (31.2%) in the course of an attack from other topography (optic neuritis or acute myelitis). One patient (6.3%) presented an asymptomatic spinal cord lesion irrespective of clinical manifestation. No asymptomatic lesion was described in optic nerve MRI. In acute phase exams, longitudinally extensive transverse myelitis (13/19 vs 8/24; p = 0.033), cervical myelitis (15/19 vs 10/24, p = 0.028), lumbar myelitis (5/19 vs 0/24; p = 0.012), and a higher number of segments [median 8 (range 4-17) vs 3.5 (range 1-14); p = 0.003] were affected. CONCLUSIONS: Asymptomatic brain and spinal cord lesions can occur in pediatric-onset NMOSD, especially in the course of acute optic neuritis or myelitis. More longitudinal studies are necessary to guide recommendations on neuroimaging frequency in pediatric patients with AQP4-IgG NMOSD.

BACKGROUND: Multiple sclerosis (MS) and neuromyelitis optica spectrum disorders (NMOSD) are the most common autoimmune diseases of the central nervous system (CNS). They present chronic relapsing courses that demand treatment with disease-modifying drugs (DMDs) to prevent inflammatory activity. Disease-modifying drugs lead to immunomodulation or immunosuppression through diverse mechanisms (e.g., shifting lymphocyte and cytokine profile, suppressing specific lymphocyte subpopulations). Thus, patients are more prone to infectious complications and associated worsening of disease. OBJECTIVE: To present feasible strategies for mitigating the infection risk of MS and NMOSD treated patients. METHODS: Targeted literature review concerning the management of infection risk with an emphasis on vaccination, therapy-specific measures, and particularities of the Brazilian endemic infectious diseases' scenario. CONCLUSION: We propose a vaccination schedule, infectious screening routine, and prophylactic measures based on the current scientific evidence. Awareness of emergent tropical diseases is necessary due to evidence of demyelinating events and possible parainfectious cases of MS and NMOSD.
ANTECEDENTES: A esclerose múltipla (EM) e a doença do espectro neuromielite optica (NMOSD) são as doenças autoimunes mais comuns do sistema nervoso central (SNC). Ambas apresentam curso crônico com recaídas (surtos) e exigem tratamento com drogas modificadoras de doenças (DMDs) para a prevenção de atividade inflamatória. As DMDs levam à imunomodulação ou imunossupressão através de diversos mecanismos (por exemplo deslocando e/ou suprimindo subpopulações linfocitárias ou alterando perfil de produção de citocinas). Desta forma, os pacientes com EM ou NMOSD são mais propensos a complicações infecciosas, as quais podem levar ao agravamento de suas doenças de base. OBJETIVO: Apresentar estratégias viáveis para mitigar o risco de infecção de pacientes com EM ou NMOSD sob tratamento. MéTODOS: Revisão bibliográfica focada em manejo de risco de infecção com ênfase em vacinação, medidas específicas de tratamento e particularidades de doenças infecciosas endêmicas do Brasil. CONCLUSãO: Propomos um calendário de vacinação, rotina de triagem infecciosa e medidas profiláticas baseadas em evidências científicas atuais. A conscientização das doenças tropicais emergentes é necessária devido a evidências de eventos desmielinizantes e possíveis casos parainfecciosos de EM e NMOSD.

BACKGROUND: Neuromyelitis optica spectrum disorders (NMOSD) is a severe condition associated with high disability and low quality of life (QoL) in adults. Since this evaluation had been rarely perfomed in children, this study aimed to describe QoL in pediatric-onset NMOSD with positive aquaporin4 antibody (AQP4-IgG) patients. METHODS: This was a cross-section evaluation of patients and parents' proxy QoL from individuals enrolled in a longitudinal cohort of AQP4-IgG positive NMOSD with onset ≤ 18 years of age. RESULTS: Eighteen patients were included, sixteen girls. The mean (SD) age at disease onset was 11.5 (3.6) years. Eleven of patients experienced disability during a mean (SD) of 8.3 (5.3) years of follow-up. NMOSD had impact in QoL in 10 patients, being associated with higher EDSS and poor academic performance at last follow-up. Results from the PedsQL inventory for 13 patients and 10 parents disclosed low QoL specially in emotional functioning. CONCLUSION: This study indicates impaired quality of life, high disability and high impact of the disease in daily life of adolescents and young adults with pediatric onset NMOSD.

The Scientific Department of Neuroimmunology of the Brazilian Academy of Neurology (DCNI/ABN) and Brazilian Committee for Treatment and Research in Multiple Sclerosis and Neuroimmunological Diseases (BCTRIMS) provide recommendations in this document for vaccination of the population with demyelinating diseases of the central nervous system (CNS) against infections in general and against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19. We emphasize the seriousness of the current situation in view of the spread of COVID-19 in our country. Therefore, reference guides on vaccination for clinicians, patients, and public health authorities are particularly important to prevent some infectious diseases. The DCNI/ABN and BCTRIMS recommend that patients with CNS demyelinating diseases (e.g., MS and NMOSD) be continually monitored for updates to their vaccination schedule, especially at the beginning or before a change in treatment with a disease modifying drug (DMD). It is also important to note that vaccines are safe, and physicians should encourage their use in all patients. Clearly, special care should be taken when live attenuated viruses are involved. Finally, it is important for physicians to verify which DMD the patient is receiving and when the last dose was taken, as each drug may affect the induction of immune response differently.

Acute disseminated encephalomyelitis (ADEM) is an immune-mediated central nervous system (CNS) disorder, characterized by polyfocal symptoms, encephalopathy and typical magnetic resonance imaging (MRI) findings, that especially affects young children. Advances in understanding CNS neuroimmune disorders as well as the association of myelin oligodendrocyte glycoprotein antibody (MOG-Ab) with both monophasic and recurrent forms of ADEM have led to new insights into its definition, management and outcome. In this review, we aim to provide an update based on current epidemiologic, clinical, radiological and immunopathological aspects and clinical outcome of ADEM.
RESUMEN
OBJECTIVE: To describe the clinical phenotypes, treatment response, and outcome of children with antibodies against aquaporin-4 (AQP4-Ab) neuromyelitis optica spectrum disorder (NMOSD). METHODS: Retrospective, multicenter, and multinational study of patients with AQP4-Ab NMOSD aged <18 years at disease onset from a center in Brazil and 13 European centers. Data on demographics, clinical findings, and laboratory results were analyzed; calculation of annualized relapse rates (ARRs) pre- and on-treatment with disease-modifying therapies (DMTs) and of ORs for predictors of poor outcome was performed. RESULTS: A total of 67 children were identified. At last follow-up (median 4 years, interquartile range 2-10 years), 37/67(57.8%) were found to have permanent disability. A more severe disease course was seen in the non-White ethnicity with both a shorter time to first relapse (p = 0.049) and a worse Expanded Disability Status Scale score at last follow-up (p = 0.008). The median ARR on treatment was 0.18 on azathioprine (n = 39, range 0-4), 0 on mycophenolate mofetil (n = 18, range 0-3), and 0 on rituximab (n = 29, range 0-2). No patient treated with rituximab as first-line therapy relapsed. Optic neuritis at onset was associated with a poor visual outcome below 20/200 (OR 8.669, 95% CI 1.764-42.616, p = 0.008), and a younger age at onset was associated with cognitive impairment (OR 0.786, 95% CI 0.644-0.959, p = 0.018). CONCLUSIONS: AQP4-Ab NMOSD in children is an aggressive disease with permanent disabilities observed in over half the cohort. All DMTs were associated with a reduction of ARR. First-line rituximab prevented further clinical relapses. International consensus on treatment protocols for children is required to reduce heterogeneity of treatment regimens used worldwide. CLASSIFICATION OF EVIDENCE: This study provides Class IV evidence that for children with AQP4-Ab NMOSD, all DMTs, particularly first-line rituximab, reduced the ARR and prevented further clinical relapses.

RESUMO O DC de Neuroimunologia da ABN e o BCTRIMS trazem, nesse documento, as recomendações sobre vacinação da população com doenças desmielinizantes do sistema nervoso central (SNC) contra infecções em geral e contra o coronavírus da síndrome respiratória aguda grave 2 (SARS-CoV-2), causador da COVID-19. Destaca-se a gravidade do atual momento frente ao avanço da COVID-19 em nosso País, o que torna mais evidente e importante a criação de guia de referência para orientação aos médicos, pacientes e autoridades de saúde pública quanto à vacinação, meio efetivo e seguro no controle de determinadas doenças infecciosa. O DCNI/ABN e o BCTRIMS recomendam que os pacientes com doenças desmielinizantes do SNC (ex., EM e NMOSD) sejam constantemente monitorados, quanto a atualização do seu calendário vacinal, especialmente, no início ou antes da mudança do tratamento com uma droga modificadora de doença (DMD). É importante também salientar que as vacinas são seguras e os médicos devem estimular o seu uso em todos os pacientes. Evidentemente, deve ser dada especial atenção às vacinas com vírus vivos atenuados. Por fim, é importante que os médicos verifiquem qual DMD o paciente está em uso e quando foi feita a sua última dose, pois cada fármaco pode interagir de forma diferente com a indução da resposta imune.

A hanseníase é uma doença infecciosa, de evolução crônica, causada pelo Mycobacterium leprae. É uma enfermidade estigmatizante e tem um passado de discriminação e isolamento dos doentes. O presente estudo objetiva verificar a avaliabilidade do Programa Nacional de Eliminação da Hanseníase para uma futura avaliação sistemática. A coleta de dados foi feita por meio de entrevistas com informantes-chaves, nas esferas estadual e municipal de governo, e observação sistemática in loco, para posterior comparação com o preconizado pelo plano selecionado. Houve grandes diferenças na definição do Programa e de seus objetivos por parte dos gestores. Há reuniões avaliativas em quase todos os níveis do sistema; as informações quanto ao controle dos comunicantes e a adesão ao tratamento, entretanto, ainda são discordantes. Os recursos estão sendo repassados como o previsto pela legislação brasileira, mas a falta de uma verba destinada exclusivamente para o controle da hanseníase dificulta seu manejo. Evidenciou-se que treinamentos para os profissionais de saúde são realizados, no entanto eles ainda parecem insuficientes. Concluiu-se que o Programa Nacional de Eliminação da Hanseníase é avaliável.
Leprosy is an infectious disease, of chronic evolution, caused by Mycobacterium leprae. Its a stigmatizating illness with a past of discrimination and isolation of patients. This study aims verify the availability of the National Program of Leprosy?s Elimination for a future systematic evaluation of the Program. Data collection was done through interviews with key informers, in the statel and municipal levels of government, and systematic observation in-loco, for posterior comparison with the recommended by selected plan. There was a large variability in the definition of the Program and its goals by the managers. There were evaluative reunions at almost every system level; the information about the control of contacts and treatment adhesion, however, are still discordant. The resources are being transfered like determined by the Brazilian legislation, but the absence of an exclusive sum designated for leprosy control make it difficult to manage it. It was evidenced that training for the health workers has been realized; however, it still seems insufficient. We conclude that the National Program of Leprosy?s Elimination may be evaluated.
La Enfermedad de Hansen es una enfermedad infecciosa, de evolucíon crónica, causada por el Mycobacterium leprae. Es una afección estigmatizante y tiene una historia de discriminación y aislamiento de los enfermos. Este estudio tiene como objetivo determinar la evalución del Programa Nacional para la Eliminación de la Enfermidad de Hansen para futura evaluación sistemática del Programa. La recolección de datos se realizó mediante entrevistas con informantes clave en los niveles estadual y municipal del gobierno, y observación sistemática in loco, para compararlos con las recomendaciones del plan seleccionado. Hubo gran variabilidad en la definición del Programa y sus objetivos por los gestores. Se realizan reuniones evaluativas en casi todos los niveles del sistema, la información relativa al seguimiento de los contactos y la adherencia al tratamiento, sin embargo, siguen siendo discordantes. Los fondos se transfieren de acuerdo a lo dispuesto por la legislación brasileña, pero la falta de fondos destinados exclusivamente para el control de la Enfermedad de Hansen dificulta su gestión. Se evidenció que la formación de los trabajadores de la salud se ha realizado, sin embargo, parece todavía insuficiente. Se concluyó que el Programa Nacional para la Eliminación de la Enfermedad de Hansen es evaluable.
