    Cerebrospinal Fluid Aquaporin-4 Antibody Levels in Neuromyelitis Optica Attacks
    (2014) SATO, Douglas Kazutoshi; CALLEGARO, Dagoberto; JORGE, Frederico M. de Haidar; NAKASHIMA, Ichiro; NISHIYAMA, Shuhei; TAKAHASHI, Toshiyuki; SIMM, Renata Faria; APOSTOLOS-PEREIRA, Samira Luisa; MISU, Tatsuro; STEINMAN, Lawrence; AOKI, Masashi; FUJIHARA, Kazuo
    To elucidate immunopathogenetic roles of aquaporin-4 antibodies in the cerebrospinal fluid (CSF) of neuromyelitis optica spectrum disorders (NMOSD), we analyzed aquaporin-4 antibody titers, cellular and inflammatory markers in the CSF collected from 11 aquaporin-4 antibody seropositive patients. The CSF aquaporin-4 antibody levels during attacks (but not in sera) closely correlated with pleocytosis, inflammatory cytokines including interleukin-6 that can regulate antibody-producing plasmablasts, and glial fibrillary acidic protein levels in the CSF. The amount of aquaporin-4 antibodies present in the central nervous system may have therapeutic implications, as it is associated with astrocyte injury and inflammatory responses during NMOSD attacks.

    Characterization of pain syndromes in patients with neuromyelitis optica
    (2020) VALERIO, Fernanda; APOSTOLOS-PEREIRA, Samira L.; SATO, Douglas Kazutoshi; CALLEGARO, Dagoberto; LUCATO, Leandro Tavares; BARBOZA, Victor Rosseto; SILVA, Valquiria A.; GALHARDONI, Ricardo; RODRIGUES, Antonia L. de Lima; TEIXEIRA, Manoel Jacobsen; ANDRADE, Daniel Ciampi de
    Background Pain is common and refractory in spinal cord injury (SCI). Currently, most studies evaluated pain in male-predominant traumatic-SCI. Also, concomitant secondary pain syndromes and its temporal evolution were seldom reported. Methods We aimed to prospectively describe the main and secondary pain and its associated factors in inflammatory-SCI evaluating neuromyelitis optica (NMO) patients. In-remission NMO patients underwent neurological, imaging and autoantibody evaluations. Questionnaires detailing main and secondary pains, functional state, mood, catastrophizing, quality of life (QoL) and ""non-motor symptoms"" were used at two time points. Results Pain was present in 53 (73.6%) of the 72 patients included. At-level neuropathic pain was the most common main pain syndrome, affecting 32 subjects (60.4% of those with pain). Over 70% (n = 38) of this cohort reported two pain syndromes. Those without pain were significantly younger (26.1 +/- 12.7 y.o. in those without pain and 40.1 +/- 12.5, 37.2 +/- 11.4 y.o. in those whose main pain was neuropathic and non-neuropathic, respectively,p = .001), and no differences in the inflammatory status were observed between groups. On follow-up, one-fifth (n = 11) had a different main pain syndrome from the first visit. Pain impacted QoL as much as disability and motor strength. Conclusion Pain is a prevalent and disabling non-motor symptom in NMO-SCI. Most patients experience more than one pain syndrome which can change in time even in the absence of clinical relapse. Age of the inflammatory-SCI was a major determinant of pain. Acknowledging temporal changes and multiplicity of pain syndromes in NMO-SCI may give insights into more precise designs of clinical trials and general management of pain in SCI. Significance In this longitudinal study with NMO-related SCI, pain affected almost three-quarters of patients with NMO. Over 70% have more than one pain syndrome and at-level neuropathic pain is the most common type of pain syndrome. Patients without pain were significantly younger but had the same burden of inflammatory lesions than those with pain. During follow-up, up to one fifth of patients presented with changes in the main pain syndromes, which can occur even in the absence of clinical activity of the inflammatory disease. In this cohort, Pain affected quality of life as much as disability or motor strength.

    MOG-IgG-Associated Optic Neuritis, Encephalitis, and Myelitis: Lessons Learned From Neuromyelitis Optica Spectrum Disorder
    (2018) PASSOS, Giordani Rodrigues dos; OLIVEIRA, Luana Michelli; COSTA, Bruna Klein da; APOSTOLOS-PEREIRA, Samira Luisa; CALLEGARO, Dagoberto; FUJIHARA, Kazuo; SATO, Douglas Kazutoshi
    Antibodies against myelin oligodendrocyte glycoprotein (MOG-IgG) have been found in some cases diagnosed as seronegative neuromyelitis optica spectrum disorder (NMOSD). MOG-IgG allowed the identification of a subgroup with a clinical course distinct from that of NMOSD patients who are seropositive for aquaporin-4-IgG antibodies. MOG-IgG is associated with a wider clinical phenotype, not limited to NMOSD, with the majority of cases presenting with optic neuritis (ON), encephalitis with brain demyelinating lesions, and/or myelitis. Therefore, we propose the term MOG-IgG-associated Optic Neuritis, Encephalitis, and Myelitis (MONEM). Depending on the clinical characteristics, these patients may currently be diagnosed with NMOSD, acute disseminated encephalomyelitis, pediatric multiple sclerosis, transverse myelitis, or ON. With specific cell-based assays, MOG-IgG is emerging as a potential biomarker of inflammatory disorders of the central nervous system. We review the growing body of evidence on MONEM, focusing on its clinical aspects.

    Reducing infection risk in multiple sclerosis and neuromyelitis optica spectrum disorders: a Brazilian reference center's approach
    (2022) GOMES, Ana Beatriz Ayroza Galvao Ribeiro; FEO, Lucas Bueno; SILVA, Guilherme Diogo; DISSEROL, Caio Cesar Diniz; PAOLILO, Renata Barbosa; LARA, Amanda Nazareth; TONACIO, Adriana Coracini; MENDES, Maria Fernanda; PEREIRA, Samira Luisa Apostolos; CALLEGARO, Dagoberto
    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.

    Longitudinal analysis of verbal episodic memory in patients with relapsing-remitting multiple sclerosis
    (2018) BOA, Izadora Nogueira Fonte; RIMKUS, Carolina de Medeiros; COMPANHOLO, Kenia Repiso; PEREIRA, Samira Luisa Apostolos; JUNQUEIRA, Thiago de Faria; MACHADO, Melissa de Almeida Rodrigues; CALLEGARO, Dagoberto; OTACLUY, Maria Concepcion Garcia; LEITE, Claudia da Costa; MIOTTO, Eliane Correa
    Objective: A 4.5-year follow-up study was conducted to characterize baseline verbal episodic memory (VEM) and its behavior and to assess the effects of relapsing-remitting multiple sclerosis (RRMS) on this domain. Methods: Twenty-nine patients with RRMS underwent two neuropsychological assessments performed an average of 4.5 years apart. Twenty-six control participants underwent a single neuropsychological assessment. A significance level of p < 0.005 was adopted to denote a significant difference between the groups on the Mann Whitney and Wilcoxon paired statistical analyses. Results: No statistical difference was found in the results of the VEM tests between the first and second neuropsychological assessments of the patients. However, a statistical difference was evident between the patient and control groups in the results of the VEM tests. Conclusion: The patient group showed changes in the VEM relative to the control group.After approximately 4.5 years of disease, the patient performance on the VEM stabilized or improved.

    Persistent MOG-IgG positivity is a predictor of recurrence in MOG-IgG-associated optic neuritis, encephalitis and myelitis
    (2019) OLIVEIRA, Luana Michelli; APOSTOLOS-PEREIRA, Samira Luisa; PITOMBEIRA, Milena Sales; TORRETTA, Pedro Henrique Bruel; CALLEGARO, Dagoberto; SATO, Douglas Kazutoshi
    Background: MOG-IgG-associated optic neuritis, encephalitis and myelitis (MONEM) is a recently recognized group of inflammatory central nervous system (CNS) disorders distinct from multiple sclerosis and neuromyelitis optica spectrum disorders. Limited data are available regarding the predictors of relapse in this condition. Objective: We aimed to evaluate the longitudinal serostatus of patients with MOG-IgG and to correlate serostatus with long-term clinical outcomes. Methods: Of 574 consecutive patients who presented with demyelinating inflammatory CNS disorders, we included 31 patients who were MOG-IgG-positive. Patients with MOG-IgG were followed up from 2011 to 2017 at the School of Medicine, University of SAo Paulo, Brazil. Results: Relapsing disease occurred in 23 out of 31 patients (74%), while 8 (26%) exhibited a monophasic course. All monophasic patients, as well as the majority of relapsing patients, became seronegative during clinical remission. Patients exhibiting disease activity in the last 2years were more likely to remain positive, with higher medium titres than those found in patients in clinical remission. Conclusion: MOG-IgG patients usually present with a relapsing course, and the risk of relapse was associated with longitudinally persistent MOG-IgG seropositivity. In contrast, patients who experienced a single attack became spontaneously seronegative for MOG-IgG during long-term follow-up.

    Primary angiitis of the central nervous system as a mimic of multiple sclerosis: A case report
    (2022) TIEPPO, Eduardo Macedo de Souza; SILVA, Tomas Fraga Ferreira da; ARAUJO, Roger Santana; SILVA, Guilherme Diogo; PAES, Vitor Ribeiro; RIMKUS, Carolina de Medeiros; TINONE, Gisela; PEREIRA, Samira Apostolos; CALLEGARO, Dagoberto
    Background: Primary angiitis of the central nervous system is a rare inflammatory vasculopathy and it is a difficult diagnosis to make because of its kaleidoscopic presentation and its multiple mimics, including multiple sclerosis. Case presentation: A 21-year-old men presented a four-year history of progressive gait deterioration. Magnetic resonance imaging of the brain and spine showed hyperintense round-shaped lesions on T2 images, many with contrast enhancement, in supra/infratentorial and spinal segments. He received treatment for multiple sclerosis but presented clinical worsening, and follow-up neuroimaging showed persistent contrast enhancement lesions and a cerebellar hematoma. Brain biopsy was performed and demonstrated inflammatory infiltrations in blood vessels. The patient received 6 monthly schedules of 5 g methylprednisolone and 1 g cyclophosphamide with clinical stabilization. Discussion: Our patient presented a primary angiitis central nervous system according to the Birnbaum and Hellmann proposed criteria. This case reinforces the importance of advancing the differential diagnosis of patients that present red flags in brain neuroimaging. Conclusion: The presence of the micro/macrobleeds and persistent contrast enhancing lesions should raise the suspicion of vasculitis in the differential diagnosis of 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.

    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.

    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. Data collected between March 19 and July 25, 2020, were uploaded at the REDONE.br platform. Inclusion criteria were as follows: (1) NMOSD diagnosis according to the 2015 International Panel Criteria and (2) confirmed SARS-CoV2 infection (reverse transcription-polymerase chain reaction or serology) or clinical suspicion of COVID-19, diagnosed according to Center for Disease Control / Council of State and Territorial Epidemiologists (CDC/CSTE) case definition. Demographic and NMOSD-related clinical data, comorbidities, disease-modifying therapy (DMT), COVID-19 clinical features, and severity were described. Results Among the 2,061 pwNMOSD followed up by Brazilian neurologists involved on the registry of COVID-19 in pwNMOSD at the REDONE.br platform, 34 patients (29 women) aged 37 years (range 8-77), with disease onset at 31 years (range 4-69) and disease duration of 6 years (range 0.2-20.5), developed COVID-19 (18 confirmed and 16 probable cases). Most patients exhibited mild disease, being treated at home (77%); 4 patients required admission at intensive care units (severe cases); and 1 patient died. Five of 34 (15%) presented neurologic manifestations (relapse or pseudoexacerbation) during or after SARS-CoV2 infection. Discussion Most NMOSD patients with COVID-19 presented mild disease forms. However, pwNMOSD had much higher odds of hospitalization and intensive care unit admission comparing with the general Brazilian population. The frequency of death was not clearly different. NMOSD disability, DMT type, and comorbidities were not associated with COVID-19 outcome. SARS-CoV2 infection was demonstrated as a risk factor for NMOSD relapses. Collaborative studies using shared NMOSD data are needed to suitably define factors related to COVID-19 severity and neurologic manifestations.
