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.

RESUMO O crescent arsenal terapêutico na esclerose múltipla (EM) tem permitido tratamentos mais efetivos e personalizados, mas a escolha e o manejo das terapias modificadoras da doença (TMDs) tem se tornado cada vez mais complexos. 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.

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.

Oligoclonal Bands in Cerebrospinal Fluid of Black Patients with Multiple Sclerosis.

Genetic susceptibility is a well-recognized factor in the onset of multiple sclerosis (MS). The objective of this study was to determine the frequency of oligoclonal bands (OCB) restricted to the cerebrospinal fluid, in an ethnically mixed group of MS patients in the city of São Paulo, Brazil. Techniques used to detect OCB consisted of isoelectric focusing followed by immunoblotting. OCB were found in 49 (54.4%) out of 90 patients with clinically definite MS; out of the 23 brown/black patients, 17 (73.9%) were OCB+; out of the 66 white patients, 32 (48.5%) were OCB+; and the only patient yellow was OCB+ (p = 0.05). Analysis of the IgG index was also consistent with the findings, but with lower statistical significance. The data presented in our study show that the ethnic differences in MS extend to the immune response.

Nearly one-half of Brazilian patients with multiple sclerosis using natalizumab are DNA-JC virus positive.

OBJECTIVE: Natalizumab is a new and efficient treatment for multiple sclerosis (MS). The risk of developing progressive multifocal leukoencephalopathy (PML) during the use of this drug has created the need for better comprehension of JC virus (JCV) infection. The objective of the present study was to assess the prevalence of JCV-DNA in Brazilian patients using natalizumab. METHOD: Qualitative detection of the JCV in the serum was performed with real-time polymerase chain reaction (PCR). RESULTS: In a group of 168 patients with MS who were undergoing treatment with natalizumab, JCV-DNA was detectable in 86 (51.2%) patients. DISCUSSION: Data on JCV-DNA in Brazil add to the worldwide assessment of the prevalence of the JCV in MS patients requiring treatment with natalizumab.

The effects of long-term exposure to disease-modifying drugs during pregnancy in multiple sclerosis.

BACKGROUND AND OBJECTIVE: Women with multiple sclerosis (MS) who intend to get pregnant are often advised to discontinue disease modifying therapy (DMT) prior to conception. This recommendation is not based on medical evidence and may interfere with disease control by immunomodulatory drugs. The present study was designed to help discuss the effect of DMT for MS on pregnancy and on disease course. PATIENTS AND METHODS: Retrospective data from 152 pregnancies of 132 women with MS were collected by the physician in charge of the case. All data were entered into a specific file for qualitative and quantitative statistical analysis. RESULTS: From the total group of patients, 89 pregnancies occurred without any exposure to MS drugs, while 61 pregnancies occurred with at least eight weeks of exposure to MS immunomodulatory drugs. The rate of obstetric and neonatal complications was similar in both groups, except for the newborn weight and height which was smaller for mothers receiving medications. Mothers' post-delivery relapse rate and EDSS scores in the follow-up period were significantly higher in the absence of treatment. CONCLUSION: It is possible that, with further such supportive data, international guidelines on MS treatment in young women who intend to get pregnant may need to be revised.

Study of oligoclonal bands restricted to the cerebrospinal fluid in multiple sclerosis patients in the city of São Paulo / Estudo de bandas oligoclonais restritas ao líquido cefalorraquidiano em pacientes com esclerose múltipla na cidade de São Paulo

The frequency of oligoclonal bands (OCB) restricted to the cerebrospinal fluid (CSF) from patients with multiple sclerosis (MS) varies widely in different populations. The objective of this study was to determine the frequency of these OCB in a group of MS patients in the city of São Paulo. Techniques used to detect OCB consisted of isoelectric focusing followed by immunoblotting. Oligoclonal bands were found in 49 (54.4 percent) out of 90 patients with clinically definite MS; in (31.2 percent) of the 16 patients with clinically isolated syndrome; in 7 (17.9 percent) of 39 patients with inflammatory disorders of the central nervous system (IDCNS), and in none of the individuals with no neurological condition (control group). The specificity of the method was 100 percent when compared to the control group and 82.1 percent when compared to the IDCNS group. These results suggest that the frequency of CSF OCB is much lower in Brazilian MS patients from São Paulo city than that reported in MS series from Caucasian populations.

A frequência da detecção de bandas oligoclonais (BOC) restritas ao líquido cerebrorraquidiano (LCR) em pacientes com esclerose múltipla (EM) varia amplamente em diferentes populações. O objetivo deste estudo foi determinar a frequência destas BOC em pacientes com EM em amostra de população da cidade de São Paulo. A técnica utilizada para a detecção das BOC foi a focalização isoelétrica, seguida do immunoblotting. BOC foram detectadas: em 49 (54,4 por cento) de 90 pacientes com EM clinicamente definida; em 5 (31,2 por cento) de 16 pacientes com síndrome clínica isolada; em 7 (17,9 por cento) de 30 pacientes com doenças inflamatórias do sistema nervoso central (DISNC); e em nenhum indivíduo sem doença neurológica. A especificidade do método foi 100 por cento quando comparada ao grupo controle e 82,1 por cento quando comparada ao grupo de DISNC. Estes resultados sugerem que a freqüência de BOC no LCR é mais baixa em pacientes da cidade de São Paulo portadores de EM do que aquelas descritas em populações caucasianas.

Pregnancy and multiple sclerosis: the initial results from a Brazilian database.

PURPOSE: Pregnancy management poses an extra challenge to physicians and their multiple sclerosis (MS) patients. There are few papers reporting databases on the subject. METHOD: Brazilian database from nine MS clinical and research units, with complete data on 47 pregnant women (49 pregnancies). RESULTS: Despite relatively high exposure to MS medications, no birth defects were reported. Low birth weight and prematurity were similar to those for developing countries. Three complications may have been associated with these medications, while three others were considered to be of purely obstetric nature. CONCLUSION: Our results confirm previous findings on lower relapse rate during pregnancy and add to the present literature informing on data related to drug exposure.

PROPÓSITO: O manejo da gravidez cria um desafio extra aos médicos e aos pacientes com esclerose múltipla (EM). Existem poucos trabalhos relatando bases de dados neste tema. MÉTODO: Base de dados brasileira de nove centros clínicos e de pesquisa na EM, com dados completos de 47 mulheres grávidas (49 gestações). RESULTADOS: Apesar da exposição a drogas para EM ter sido relativamente alta, não foram registradas malformações. Baixo peso e prematuridade foram semelhantes àqueles de países em desenvolvimento. Três complicações podem ter sido associadas a drogas, enquanto outras três foram consideradas como sendo de natureza puramente obstétrica. CONCLUSÃO: Nossos resultados confirmam os achados de menor taxa de surtos na gestação e adicionam dados relacionados a exposição a drogas, na literatura atual.

Evaluation of the health-related quality of life in elderly patients according to the type of hip fracture: femoral neck or trochanteric.

OBJECTIVE: To evaluate the effect the type of hip fracture (femoral neck or trochanteric) has on the Health-Related Quality of Life of elderly subjects. METHODS: Forty-five patients with hip fractures (mean 74.30 +/- 7.12 years), 24 with a femoral neck fracture and 21 with a trochanteric fracture, completed the 36-item Short Form Health Survey (SF-36) at baseline and four months after fracture. The Health-Related Quality of Life scores were compared according to fracture type, undisplaced and displaced femoral neck fractures, and stable and unstable trochanteric fractures. RESULTS: Compared to baseline, all patients scored lower in the physical functioning, role limitation-physical, bodily pain and vitality categories four months after the fracture had occurred. The SF-36 scores for all the scales did not differ significantly between patients with femoral neck versus trochanteric fractures, or between patients with displaced versus undisplaced femoral neck fractures and stable versus unstable trochanteric fractures. CONCLUSIONS: The mental and physical quality of life of elderly patients with a hip fracture is severely impaired one month after fracture, with partial recovery by the end of the fourth month. The negative impact on the Health-Related Quality of Life did not differ significantly according to fracture type.

[Health-related quality of life in multiple sclerosis]. / Qualidade de vida em portadores de esclerose múltipla.

Multiple sclerosis (MS) is a chronic disease which may exert significant effects on the life of patients. Traditional outcome measures in MS lack in consider the effects of the disease on health-related quality of life (HRQoL). The goal of this study is to measure HRQoL in MS patients in the city of Uberlândia, State of Minas Gerais, Brazil. The Brazilian version of the SF-36 was applied in 23 MS patients and in 69 subjects of general population (blood donors) in Uberlândia. MS patients scored lower in all SF-36 scales than do the general population, principally in physical function domains. Patients with EDSS scores < or =3.5 had higher mean scores in four domains than do the patients with EDSS scores > or =4.0, and lower in all domains than control group. Depressive symptoms and heat intolerance showed correlation with SF-36 domains and components. In conclusion, MS patients have a significant negative impact on all HRQoL domains measured by SF-36, compared with general population, even in the stages with lower disability.

Qualidade de vida em portadores de esclerose múltipla / Health-related quality of life in multiple sclerosis

A esclerose múltipla (EM) é doença crônica que pode causar repercussões importantes na vida dos pacientes. Medidas tradicionais de evolução na EM não consideram os efeitos da doença na qualidade de vida relacionada à saúde (QVRS). O objetivo deste estudo é avaliar o impacto da EM na QVRS de portadores residentes em Uberlândia - MG. O SF-36 foi aplicado em 23 portadores de EM e em 69 doadores de sangue. Os portadores de EM apresentaram escores mais baixos que a população geral, principalmente nos domínios de função física. Pacientes com EDSS <3,5 apresentam escores maiores em quatro domínios do SF-36 que aqueles com EDSS >4,0, e menores em todos os domínios em relação ao grupo controle. Sintomas depressivos e intolerância ao calor mostram correlação com domínios e componentes do SF-36. Concluindo, a EM provoca impacto negativo significante em todos os domínios do SF-36, comparados à população geral, mesmo nas fases de menor incapacidade.
