Recommendations by the Scientific Department of Neuroimmunology of the Brazilian Academy of Neurology (DCNI/ABN) and the Brazilian Committee for Treatment and Research in Multiple Sclerosis and Neuroimmunological Diseases (BCTRIMS) on vaccination in general and specifically against SARS-CoV-2 for patients with demyelinating diseases of the central nervous system.

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.

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.

Evaluation of diagnosis and treatment practices of Brazilian neurologists among patients with multiple sclerosis.

BACKGROUND: Recent changes to the diagnostic criteria for multiple sclerosis (MS) and new medications have had a major impact on the way in which specialists manage the disease. OBJECTIVE: To investigate factors considered by Brazilian neurologists in managing MS, and to identify how these contribute to diagnosis and treatment. METHODS: Potential participants were selected by a steering committee (MS experts who developed this survey). Only MS specialists were included in the study (neurologists who had completed a neuroimmunology fellowship or who were treating more than 30 MS patients). Links to the online questionnaire were distributed between March 2019 and January 2020. This questionnaire was composed of sections with hypothetical MS scenarios. RESULTS: Neurologists from 13 Brazilian states responded to the survey (n = 94). In the clinically isolated syndrome (CIS) scenario, the respondents agreed to treat patients with a high risk of MS diagnosis, whereas in the radiologically isolated syndrome (RIS) half of the respondents opted not to treat, even among high-risk patients. In cases of low-activity relapsing-remitting MS (RRMS), the choice of treatment was distributed among interferon beta, glatiramer acetate and teriflunomide, which were changed to fingolimod and natalizumab, as RRMS severity increased. The topics in which disagreement was found included practices regarding use of disease-modifying therapy (DMT) for pregnant patients and the washout period required for some DMTs. CONCLUSIONS: This study enabled identification of areas of agreement and disagreement about MS treatment among Brazilian neurologists, which can be used to update future protocols and improve patient management.

GOOD QUALITY OF LIFE AFTER MORE THAN A DECADE OF LIVING DONOR LIVER TRANSPLANTATION.

BACKGROUND: Receptors of living donor liver transplantation (LDLT) have higher rate of postoperative biliary and vascular complications that may reduce posttransplant quality of life (QOL) due to the need of invasive and repetitive treatments. OBJECTIVE: The purpose of our study is to assess the various aspects of QOL of receptors undergoing LDLT after 10 years of transplantation and to identify potential factors that might be associated with impaired QOL. METHODS: Data of all patients with more than 10 years of LDLT were retrospectively evaluated. Patients were interviewed through a quality of life questionnaire (SF-36). RESULTS: From a total of 440 LT performed in 17 years (from September 1991 through December 2008), 78 patients underwent LDLT, of which 27 were alive and 25 answered completely the questionnaire. There were 17 (68%) men and 8 (32%) women, with a mean age of 38.6±18.5 years at the time of transplantation and mean follow up time of 15.1±1.9 years. The average MELD was 16.4±4.9 and the main indication for LT was hepatic cirrhosis caused by hepatitis B virus (32%). When compared to the general po-pulation, LDLT patients had lower mental health score (66.4 vs 74.5, P=0.0093) and higher vitality score (87.8 vs 71.9, P<0.001), functional aspects (94.6 vs 75.5, P=0.002), social aspects (93 vs 83.9, P=0.005), physical aspects (92 vs 77.5, P=0.006), and emotional aspects (97.33 vs 81.7, P<0.001). General health status (73.28 vs 70.2, P=0.074) and pain (78.72 vs 76.7, P=0.672) scores were similar in both groups. CONCLUSION: It is concluded that the various aspects LDLT recipients' QOF are similar to those of the general population more than a decade after the transplant, except for the mental health domain which is lower.

RESUMO CONTEXTO: Receptores de transplante hepático inter-vivo (THIV) apresentam elevada taxa de complicações biliares e vasculares pós-operatórias que podem reduzir a qualidade de vida (QV) devido à necessidade de tratamentos invasivos e repetitivos. OBJETIVO: O objetivo deste estudo é avaliar os vários aspectos da qualidade de vida dos pacientes submetidos a THIV após 10 anos de transplante e identificar possíveis fatores que possam estar associados à diminuição da QV. MÉTODOS: Os dados de todos os pacientes com mais de 10 anos de THIV foram avaliados retrospectivamente. Os pacientes foram entrevistados por meio de um questionário de qualidade de vida (SF-36). RESULTADOS: Do total de 440 transplantes hepáticos realizados em 17 anos (setembro de 1991 a dezembro de 2008), 78 pacientes foram submetidos a THIV, dos quais 27 estavam vivos e 25 responderam completamente ao questionário. Destes, 17 (68%) homens e 8 (32%) mulheres, com idade média de 38,6±18,5 anos no momento do transplante e tempo médio de acompanhamento de 15,1±1,9 anos. O MELD médio foi de 16,4±4,9 e a principal indicação para o transplante hepático foi cirrose hepática causada pelo vírus da hepatite B, 32%. Quando comparado com a população geral, os pacientes submetidos a THIV apresentaram menor escore de saúde mental (66,4 vs 74,5; P=0,0093) e escores mais altos de vitalidade (87,8 vs 71,9; P<0,001), aspectos funcionais (94,6 vs 75,5; P=0,002), aspectos sociais (93 vs 83,9; P=0,005), aspectos físicos (92 vs 77,5; P=0,006), e aspectos emocionais (97,33 vs 81,7; P<0,001). Os escores do estado geral de saúde (73,28 vs 70,2; P=0,074) e de dor (78,72 vs 76,7; P=0,672) eram similares nos dois grupos. CONCLUSÃO: Conclui-se que os vários aspectos da QV dos receptores de transplante hepático inter-vivo são semelhantes aos da população geral mais de uma década após o transplante, exceto o domínio da saúde mental que é menor.

Patients and neurologists have different perceptions of multiple sclerosis symptoms, care and challenges.

BACKGROUND: Basic steps in the management of patients with Multiple Sclerosis (MS), such as good patient understanding of the disease and active participation in its management are extremely important, as they directly influence treatment adherence and success. Therefore, this study aimed to evaluate the perception of MS patients and neurologists pertaining to the most common disease symptoms, disabilities that impact on quality of life, and patient concerns and difficulties during medical visits, as information that can be used to improve the doctor-patient relationship. METHODS: A cross-sectional study involving two groups: the first composed of neurologists and the second of patients. Participants of the first group were selected by a Steering Committee (15 predetermined neurologists representing each region of Brazil and specialized in MS and neuroimmunological disorders, who also assumed the role of creating the survey and questionnaire). Participants of the second group were selected following dissemination of a questionnaire on the AME's social networks (Amigos Múltiplos pela Esclerose, a non-governmental organization to support patients with MS). Questions about sociodemographic data, disease impact on quality of life, symptoms perception, and concerns and issues regarding disease care were put to both groups. RESULTS: A total of 317 patients and 182 neurologists answered the questionnaires. Significant divergences were found between the perceptions of patients and neurologists in relation to orientation and information given during medical appointments, and also regarding patient participation in treatment and therapy choice. Considering the topic assessing impact on quality of life, more than 70% of neurologists perceived that autonomy to work and travel, and future planning were aspects that most affected patient lives, however, almost 50% of patients reported that disease monitoring did not affect their life in any way. Analysis of data regarding MS symptoms revealed neurologists to consider physical symptoms, such as ambulation issues, imbalance, falls and urinary incontinence, to be those most interfering with patient quality of life, whereas patients considered non-physical symptoms, such as fatigue, pain, cognitive and memory problems to be more significant. Patients with primary progressive MS complained more about ambulation issues, imbalance and falls (p<0.05), when compared to patients with other disease phenotypes. CONCLUSION: Significant differences in disease perception were found in this study. While neurologists tended to overestimate the consequences and symptoms of the disease, for most patients, the disease impact on activities did not appear to be as significant, with more complaints regarding non-physical symptoms. Although neurologists described involving patients in treatment decisions and providing them with appropriate orientation during medical appointments, the opposite was reported by patients. These results may help to improve treatment adherence and disease outcomes by redefining the doctor-patient relationship.

Quality of Life after 10 Years of Liver Transplantation.

AIM: This study goal was to evaluate the long-term quality of life of patients who underwent cadaveric liver transplants (CLT) in two Brazilian hospitals. METHODS: Medical records of all patients who underwent CLT and survived over 10 years were revised. The international validated questionnaire Short-Form 36 was employed to assess the quality of life. Patients data were obtained from electronic medical records and study protocols. RESULTS: A total of 342 patients underwent CLT, of which 129 were alive and 93 fully answered the questionnaire and were included in the study. The group consisted of 62 men (66.6%) and 31 women (33.4%), with average age of 40.1±15.9 years. Follow-up time was 16±4.1 years. The most common indication of CLT was hepatic cirrhosis caused by hepatitis C virus, 24.7%. Transplanted patients had lower scores than the general population in mental health [62.9 (95%CI: 60.1-65.7,) vs. 74.5, p < 0.001]. In all other domains, transplanted patients had similar (emotional aspect limitiation, pain, and general health status) or superior (physical aspect limitation, social aspects, functional capacity, and vitality) scores than the general population. Functional capacity score was lower in patients with long-term complications, who were aged more than 50-years, and unemployed. CONCLUSIONS: The quality of life in patients with more than 10 years after CLT was similar or superior than the general population, except for the mental health domain.

Serological profile of John Cunningham virus (JCV) in patients with multiple sclerosis.

Treatment options for multiple sclerosis (MS) have changed over the last few years, bringing about a new category of drugs with more efficient profiles. However, these drugs have come with a whole new profile of potential adverse events that neurologists have to learn well and quickly. One of the most feared complications of these MS treatments is progressive multifocal leukoencephalopathy caused by the reactivation of the John Cunningham virus (JCV). OBJECTIVE: To identify the serologic profile of JCV in patients with MS. METHODS: Data on serum antibodies for JCV were obtained using the enzyme-linked immunosorbent assay provided by the STRATIFY-JCV program. RESULTS: A total of 1,501 blood tests were obtained from 1,102 patients with MS. There were 633 patients (57.1%) who were positive for antibodies for JCV and 469 patients who were negative (42.9%). Twenty-three patients became positive after initially having negative JCV antibody status. The rate of seroconversion was 18.5% over 22 months. CONCLUSION: The JCV serologic profile and seroconversion in Brazilian patients were similar to those described in other countries.

Brazilian Consensus for the Treatment of Multiple Sclerosis: Brazilian Academy of Neurology and Brazilian Committee on Treatment and Research in Multiple Sclerosis.

The expanding therapeutic arsenal in multiple sclerosis (MS) has allowed for more effective and personalized treatment, but the choice and management of disease-modifying therapies (DMTs) is becoming increasingly complex. In this context, experts from the Brazilian Committee on Treatment and Research in Multiple Sclerosis and the Neuroimmunology Scientific Department of the Brazilian Academy of Neurology have convened to establish this Brazilian Consensus for the Treatment of MS, based on their understanding that neurologists should be able to prescribe MS DMTs according to what is better for each patient, based on up-to-date evidence and practice. We herein propose practical recommendations for the treatment of MS, with the main focus on the choice and management of DMTs, as well as present a review of the scientific rationale supporting therapeutic strategies in MS.

Practical Evidence-Based Recommendations for Patients with Multiple Sclerosis Who Want to Have Children.

Multiple sclerosis (MS) management presently aims to reach a state of no (or minimal) evidence of disease activity. The development and commercialization of new drugs has led to a renewed interest in family planning, since patients with MS may face a future with reduced (or no) disease-related neurological disability. The advice of neurologists is often sought by patients who want to have children and need to know more about disease control at conception and during pregnancy and the puerperium. When MS is well controlled, the simple withdrawal of drugs for patients who intend to conceive is not an option. On the other hand, not all treatments presently recommended for MS are considered safe during conception, pregnancy and/or breastfeeding. The objective of the present study was to summarize the practical and evidence-based recommendations for family planning when our patients (women and men) have MS.Funding TEVA Pharmaceutical Brazil.

RESUMO As opções terapêuticas para esclerose múltipla (EM) modificaram-se ao longo dos últimos anos, trazendo uma nova categoria de drogas com melhor perfil de eficácia. No entanto, estas drogas vieram com um novo perfil de potenciais eventos adversos que exigem que o neurologista os reconheça bem e rapidamente. Uma das complicações mais temidas destes tratamentos para a EM é a leucoencefalopatia multifocal progressiva (LEMP), causada pela reativação do vírus John Cunningham (JCV). Objetivo: Identificar o perfil sorológico de JCV em pacientes com EM. Métodos: Dados sorológicos de JCV foram obtidos através do ensaio por enzimas imuno-adsorvidas (ELISA) fornecido pelo programa STRATIFY-JCV. Resultados: Um total de 1.501 testes sanguíneos foram obtidos de 1.102 pacientes com EM. O grupo teve 633 pacientes (57,1%) soropositivos para anticorpos anti-JCV e 469 pacientes negativos (42,9%). Vinte e três pacientes se tornaram posivitos após resultados iniciais negativos para anticorpos anti-JCV. A taxa de soroconversão foi 18,5% em 22 meses. Conclusão: O perfil sorológico do JCV e a soroconversão nos pacientes brasileiros foi semelhante àquela descrita em outros países.

Neste contexto, especialistas do Comitê Brasileiro de Tratamento e Pesquisa em Esclerose Múltipla e do Departamento Científico de Neuroimunologia da Academia Brasileira de Neurologia reuniram-se para estabelecer este Consenso Brasileiro para o Tratamento da EM, baseados no entendimento de que neurologistas devem ter a possibilidade de prescrever TMDs para EM de acordo com o que é melhor para cada paciente, com base em evidências e práticas atualizadas. Por meio deste documento, propomos recomendações práticas para o tratamento da EM, com foco principal na escolha e no manejo das TMDs, e revisamos os argumentos que embasam as estratégias de tratamento na EM.

High levels of alexithymia in patients with multiple sclerosis.

Alexithymia is a personality trait characterized by difficulties identifying and describing feelings. Some researchers describe high levels of alexithymia among patients with multiple sclerosis (MS) but literature data on this subject are scarce. OBJECTIVE: The objective of the present study was to characterize findings of alexithymia in patients with MS. METHODS: This cross-sectional case-control study included 180 patients with MS and a matched control group. Data for patients with MS included disease duration, number of demyelinating relapses and degree of neurological disability, as assessed by the Expanded Disability Scale Score (EDSS). In addition, the Hospital Anxiety and Depression (HAD) scale and the Toronto Alexithymia Scale (TAS) were used. RESULTS: There were 126 women and 54 men in each group, with median age of 37 years and median education of 16 years. Patients with MS had higher degrees of depression (p<0.01), anxiety (p=0.01) and alexithymia (p<0.01) than did control subjects. For individuals with MS, depressive traits (p<0.01), anxious traits (p=0.03), higher age (p=0.02), lower education level (p=0.02), higher degree of disability (p<0.01) and not being actively employed (p=0.03) were associated with higher rates of alexithymia. CONCLUSION: Alexithymia was a relevant finding in patients with MS.

Alexitimia é um traço de personalidade caracterizado pelas dificuldades na identificação e descrição dos sentimentos. Alguns pesquisadores descrevem altos índices de alexitimia em pacientes com esclerose múltipla (EM), porém os dados na literatura são escassos. OBJETIVO: O objetivo do presente estudo foi caracterizar achados de alexitimia em pacientes com EM. MÉTODOS: Este estudo transversal incluiu 180 pacientes com EM e um grupo controle pareado. Dados de pacientes com EM incluíram a duração da doença, número de surtos clínicos de desmielinização e grau de incapacidade neurológica avaliados pela Escala Expandida do Grau de Incapacidade (EDSS). Foram também utilizadas a escala Hospitalar de Ansiedade e Depressão (HAD) e a escala de Alexitimia de Toronto (TAS) foram utilizadas. RESULTADOS: Cada grupo era constituído por 126 mulheres e 54 homens, com mediana de idade de 37 anos e mediana de escolaridade de 16 anos. Pacientes com EM apresentaram maior grau de depressão (p<0.01), ansiedade (p=0.01) e alexitimia (p<0.01) que os controles. Para pessoas com EM, traços depressivos (p<0.01), ansiosos (p=0.03), maior idade (p=0.02), menor nível educacional (p=0.02), maior grau de incapacidade (p<0.01) e o fato de não estar ativamente trabalhando (p=0.03) levaram a maiores níveis de alexitimia. CONCLUSÃO: Alexitimia foi um importante achado em pacientes com EM.

Objective: Vitamin D has taken center stage in research and treatment of multiple sclerosis (MS). The objective of the present study was to assess the serum vitamin D levels of a large population of patients with MS and controls living in a restricted tropical area. Methods: Data from 535 patients with MS and 350 control subjects were obtained from 14 cities around the Tropic of Capricorn. Results: The mean serum 25-OH vitamin D level was 26.07 ± 10.27 ng/mL for the control subjects, and 28.03 ± 12.19 ng/mL for patients with MS. No correlation was observed between vitamin D levels and the disability of patients over the disease duration. Conclusion: At least for the region around the Tropic of Capricorn, serum levels of vitamin D typically are within the range of 20 to 30 ng/mL for controls and patients with MS.

No correlation was observed between vitamin D levels and disability of patients with multiple sclerosis between latitudes 18° and 30° South / Não foi observada correlação entre os níveis séricos de vitamina D e a incapacidade em pacientes com esclerose múltipla entre as latitudes Sul 18° e 30°

RESUMO Objetivo: Vitamina D assumiu um papel central na pesquisa e tratamento da esclerose múltipla (EM). O objetivo deste estudo foi avaliar os níveis séricos de vitamina D de pacientes com EM e controles que residem em uma área tropical. Métodos: Foram analisados dados de 535 pacientes com EM e 350 indivíduos controle em 14 cidades próximas ao Trópico de Capricórnio. Resultados: O valor médio da determinação de 25-OH vitamina D foi 26,07 ± 10,27 ng/mL para controles e 28,03 ± 12,19 ng/mL para pacientes com EM. Não houve correlação entre os níveis de vitamina D e o grau de incapacidade ao longo da duração da doença. Conclusão: Pelo menos na região que cerca o Trópico de Capricórnio, os níveis séricos de vitamina D estão entre valores de 20 a 30 ng/mL tanto para controles quanto para pacientes com EM.

Real-life experience with fampridine (Fampyra®) for patients with multiple sclerosis and gait disorders.

BACKGROUND: Fampridine is a broad-spectrum voltage-dependent potassium channel blocker that enhances synaptic transmission. The drug has been shown to be able to ameliorate conduction in demyelinated axons, thereby leading to improved gait in patients with multiple sclerosis (MS). OBJECTIVE: To assess the "real-life" efficacy and safety of fampridine prescribed for gait disorders in MS. This was an observational and prospective study carried out at MS Units participating in the Brazilian Multiple Sclerosis Study Group. METHODS: Patients with MS and gait disorders were prescribed fampridine (10 mg twice a day), irrespectively of the degree of disability determined by MS. Neurological disability determined by MS was assessed with the expanded disability scale score (EDSS). Outcomes for efficacy and safety of the drug were evaluated by the 25 foot-walk test and by the adverse events of fampridine. RESULTS: The time taken to walk 25 feet decreased by 20% or more in 62 patients (70%). Twenty-five patients were considered to be non-responders to this treatment. Improvement in walking speed was independent of improvement of disability. Mild or moderate adverse events were reported in 8% of patients. CONCLUSION: Fampridine is an efficient and safe therapeutic option for patients with MS and gait disorders.

Patients with multiple sclerosis do not necessarily consume more alcohol or tobacco than the general population / Pacientes com esclerose múltipla não necessariamente consomem mais álcool ou tabaco do que a população geral

Purpose Recent papers suggest that patients with multiple sclerosis (MS) are prone to alcohol misuse. This may be due to the combination of a lifelong and disabling disease with a psychiatric profile typical of MS. The objective of the present study was to assess these findings in a culturally different population of patients with MS.Method The present case-control transversal study assessed 168 patients with MS and 168 control subjects from Brazil.Results There were no evidence that patients with MS drank more alcohol or, smoked more than did controls. In fact, control subjects had a significantly higher alcohol consumption. The only trait associated to higher alcohol consumption was anxiety, both for patients and controls.Conclusion Unlike previous reports in the literature, patients with MS in our study did not drink or smoked more than a control population.

Propósito Artigos recentes sugerem que pacientes com esclerose múltipla (EM) tem tendência ao abuso de álcool. Isto poderia se dever à combinação de uma doença crônica e incapacitante e um perfil psiquiátrico típico da EM. O objetivo do presente estudo foi avaliar estes achados em uma população de pacientes com EM culturalmente diferente.Método O presente estudo caso-controle transversal avaliou 168 pacientes com EM e 168 controles, todos brasileiros.Resultados Não houve evidência que pacientes com EM usassem mais álcool ou tabaco do que os controles. Na verdade, os controles apresentavam um consumo significativamente maior de álcool. O único aspecto associado ao maior consumo de álcool foi a ansiedade, tanto para pacientes quanto para controles.Conclusão Ao contrário de outros dados da literatura, pacientes com EM neste nosso estudo não bebem ou fumam mais do que a população controle.
