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.

Clinical Features of COVID-19 on Patients With Neuromyelitis Optica Spectrum Disorders.

Background And Objectives: To describe the clinical features and disease outcomes of coronavirus disease 2019 (COVID-19) in patients with neuromyelitis optica spectrum disorder (NMOSD).

Methods: The Neuroimmunology Brazilian Study Group has set up the report of severe acute respiratory syndrome (SARS-CoV2) cases in patients with NMOSD (pwNMOSD) using a designed web-based case report form. All neuroimmunology outpatient centers and individual neurologists were invited to register their patients across the country.

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

Unlabelled: 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).

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.

Alternatives for reducing relapse rate when switching from natalizumab to fingolimod in multiple sclerosis.

Natalizumab is a therapeutic option for treating multiple sclerosis (MS) and is particularly efficacious for patients with highly active disease. A long washout period has been recommended between withdrawal of natalizumab and start of fingolimod (another option for treating MS). This long washout period has been associated with a significant increase in MS activity.

Central Nervous System Idiopathic Inflammatory Demyelinating Disorders in South Americans: A Descriptive, Multicenter, Cross-Sectional Study.

The idiopathic inflammatory demyelinating disease (IIDD) spectrum has been investigated among different populations, and the results have indicated a low relative frequency of neuromyelitis optica (NMO) among multiple sclerosis (MS) cases in whites (1.2%-1.5%), increasing in Mestizos (8%) and Africans (15.

How do we manage and treat a patient with multiple sclerosis at risk of tuberculosis?

Tuberculosis continues to be a serious health problem worldwide. The disease continues to be underdiagnosed and not properly treated. In conditions that affect the immune system, such as multiple sclerosis (MS), latent tuberculosis may thrive and reactivate during the use of immunomodulatory and immunosuppressive drugs.

Postpartum Treatment With Immunoglobulin Does Not Prevent Relapses of Multiple Sclerosis in the Mother.

Multiple sclerosis (MS) is a chronic, neurological, immune-mediated disease that can worsen in the postpartum period. There is no consensus on the use of immunoglobulin for prevention of disease relapses after delivery. We have shown that the controversial beneficial effect of immunoglobulin given immediately after birth could not be observed in patients with MS.

Multiple sclerosis in South America: month of birth in different latitudes does not seem to interfere with the prevalence or progression of the disease.

Objective: To assess whether the month of birth in different latitudes of South America might influence the presence or severity of multiple sclerosis (MS) later in life.

Methods: Neurologists in four South American countries working at MS units collected data on their patients' month of birth, gender, age, and disease progression.

Results: Analysis of data from 1207 MS patients and 1207 control subjects did not show any significant variation in the month of birth regarding the prevalence of MS in four latitude bands (0-10; 11-20; 21-30; and 31-40 degrees).

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.

Homozygotic intronic GAA mutation in three siblings with late-onset Pompe's disease.

Unlabelled: Pompe's disease (PD) is a metabolic myopathy caused by the accumulation of lysosomal glycogen, secondary to acid alpha-glucosidase (GAA) enzyme deficiency. Childhood and late-onset forms are described, differing by the age of onset and symptoms. In this study were analyzed affected siblings with Pompe's disease (PD) and their distinct clinical and pathological presentations.

[Clinical and epidemiologic characteristics of 20 patients with multiple sclerosis in Cuiabá-Mato Grosso, Brazil].

Multiple sclerosis is an acquired immune-mediated disease of the central nervous system that show a widely variation of clinical aspects. In Brazil, demographic and ethnical aspects show these variations as has been demonstrated by many Brazilian papers. This retrospective study evaluated epidemiological and clinical characteristics of 20 multiple sclerosis patients followed in Cuiaba, situated on Brazil middle west region.

[Hypokalemic periodic paralysis as first manifestation of hyperthyroidism: case report].

We report a case of thyrotoxicosis in a 37 year old male, in whom hypokalemic periodic paralysis was the first manifestation of the disease. We comment about the differential diagnosis with other types of periodic paralysis, and the importance of a correct diagnosis to avoid permanent muscle damage.
