    Abstract Myelin oligodendrocyte glycoprotein (MOG) is a membrane bound protein found on the surface of oligodendrocyte cells and the outermost surface of myelin sheaths. MOG is posited to play a role as a cell surface receptor or cell adhesion molecule, though there is no definitive answer to its exact function at this time. In the last few decades, there has been a recognition of anti-MOG-antibodies (MOG-Abs) in association with a variety of neurologic conditions, though primarily demyelinating and white matter disorders. In addition, MOG associated disease (MOGAD) appears to have a predilection for pediatric populations and in some patients may have a relapsing course. There has been considerable debate as to whether MOG-Abs are truly directly pathogenic or a disease biomarker associated with neuorinflammatory disease. In this manuscript we will review the current literature surrounding MOGAD, review new clinical phenotypes, discuss treatment and prognosis, and provide insight into potential future directions that studies may focus on.

    Abstract Aicardi-Goutières syndrome (AGS) is a genetic interferonopathy characterized by upregulation of type I interferon response. It is associated with increased mortality and severe disabilities. Janus Kinase (JAK) inhibitors have shown effectiveness in treatment of AGS through blocking the downstream effects of interferon activation. We illustrate post-mortem histopathologic findings in a patient with AGS who received baricitinib treatment for a duration of over 4 years, initiating at a remarkably young age of 2 months. We observed global cerebral atrophy, markedly diminished white matter, abundant calcifications involving supratentorial white matter, basal ganglia, dentate nuclei, and brainstem. This study showed profound central nervous system (CNS) sequelae despite early initiation of treatment. Our findings highlight the potential necessity for therapeutic options with enhanced CNS bioavailability.

    Abstract Autoimmune encephalitis is a common and treatable cause of encephalitis in children and adults. Individuals present with a variety of symptoms, including altered mental status, behavioral changes, irritability, insomnia, developmental regression, seizures, dyskinetic movements, and autonomic instability. Evaluation includes electroencephalography, magnetic resonance imaging, and lumbar puncture. Once infectious and other causes are reasonably ruled out, treatment should be started empirically without waiting for antibody confirmation. Early clinical suspicion is key, as the outcome depends on early initiation of immunotherapy, including corticosteroids, intravenous immunoglobulin, and/or plasmapheresis. Severe or refractory cases require other treatments, such as rituximab, cyclophosphamide, or other immunotherapies using novel monoclonal antibodies. Psychiatry should be involved early for the management of behavioral issues. Additional considerations include management of seizures and dyskinesias. ICU admission may be required for management of hypoventilation necessitating mechanical ventilation (either intrinsic or iatrogenic, eg, from sedatives), refractory seizures, and dysautonomia. Anti-N-methyl-d-aspartate receptor and other forms of autoimmune encephalitis are less often associated with neoplasia (such as ovarian teratoma) in children compared with adults, but screening and removal of tumor if present should be performed.

    Abstract Bickerstaff brainstem encephalitis is a rare, immune-mediated disorder of the brainstem and peripheral nervous system. Published knowledge of pediatric Bickerstaff brainstem encephalitis focuses on the acute phase of the disease process. This study evaluated long-term neurologic and immune sequelae of Bickerstaff brainstem encephalitis in children. A single-center retrospective chart review was performed. Clinical data, neuroimaging, polysomnograms, and serum data were reviewed. Five patients were included in this study. Four patients had no neurologic residua, and 1 patient continued to have mild bulbar dysfunction. There was neither recurrence of symptoms nor development of other neurologic or immunologic disorders at a median of 3 years after diagnosis. Review of systems was largely negative, although 2 patients endorsed symptoms consistent with mild orthostatic hypotension for 1 year after diagnosis, but these findings were not sustained. Four of 5 patients endorsed sleep dysregulation. Three patients met criteria for pediatric obstructive sleep apnea. Prognosis following pediatric Bickerstaff brainstem encephalitis is excellent although posttreatment autonomic and sleep dysregulation may reflect residua from acute phase inflammation in the peripheral nervous system and connections of the reticular activating formation of the brainstem, although this was time limited. Further prospective, multicenter, analysis is warranted.

    Abstract The novel SARS-CoV-2 has infected over 48 million persons around the world. Children have been spared with regards to symptoms and sequelae of this highly infectious virus and in those with neurologic issues, the virus has not been present in the cerebrospinal fluid. Here, the authors present the first case of metabolic stroke-like episode with SARS-CoV-2 present in the cerebrospinal fluid in a child with a FARS2 deficiency. This report suggests a possible association of SARS-COV-2 infection and metabolic stroke-like episode, even in the absence of a phenotype classically associated with metabolic stroke-like episodes.
