    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.

    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.
