Axicabtagene Ciloleucel in Patients Ineligible for ZUMA-1 Because of CNS Involvement and/or HIV: A Multicenter Experience.

Secondary central nervous system lymphoma (SCNSL) is associated with poor prognosis and new therapeutic approaches are needed. The pivotal trial that led to US Food and Drug Administration (FDA) approval of axicabtagene ciloleucel excluded patients with SCNSL and human immunodeficiency virus. In this multi-institutional retrospective study, 14 SCNSL patients treated with axicabtagene ciloleucel, 3 of whom had human immunodeficiency virus, experienced rates of severe neurotoxicity and complete response of 32% and 58%, respectively.

Vaccination Against SARS-CoV-2 in Neuroinflammatory Disease: Early Safety/Tolerability Data.

Background: Patients with autoimmune disease and on immunotherapy were largely excluded from seminal anti-SARS-CoV-2 vaccine trials. This has led to significant vaccine hesitancy in patients with neuroinflammatory diseases (NID); including, but not limited to: multiple sclerosis (MS), neuromyelitis optica spectrum disorders (NMOSD), neurosarcoidosis and myelin oligodendrocyte antibody-mediated disease (MOG-AD). Data is urgently needed to help guide clinical care in the NID population.

Neuroinflammation Associated With Tumor Necrosis Factor-α Inhibitor Exposure.

Objective: To identify the frequency and clinical spectrum of neuroinflammation associated with exposure to tumor necrosis factor-α inhibitors (TNFi).

Methods: We performed a single-system retrospective cohort study. Adults in the Yale New Haven Health System with documented use of any US Food and Drug Administration-approved TNFi between 2007 and 2017 were identified via automated review of the electronic medical record.

Neurologic Safety Monitoring of COVID-19 Vaccines: Lessons From the Past to Inform the Present.

The spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has triggered a global effort to rapidly develop and deploy effective and safe coronavirus disease 2019 (COVID-19) vaccinations. Vaccination has been one of the most effective medical interventions in human history, although potential safety risks of novel vaccines must be monitored, identified, and quantified. Adverse events must be carefully assessed to define whether they are causally associated with vaccination or coincidence.

Neurological Immunotoxicity from Cancer Treatment.

The emergence of immune-based treatments for cancer has led to a growing field dedicated to understanding and managing iatrogenic immunotoxicities that arise from these agents. Immune-related adverse events (irAEs) can develop as isolated events or as toxicities affecting multiple body systems. In particular, this review details the neurological irAEs from immune checkpoint inhibitors (ICI) and chimeric antigen receptor (CAR) T cell immunotherapies.

Worldwide survey of neurologists on approach to autoimmune encephalitis.

Objective: To explore practice differences in the diagnosis and management of autoimmune encephalitis (AE), which is complicated by issues with sensitivity/specificity of antibody testing, nonspecific MRI/EEG/CSF findings, and competing differential diagnoses.

Methods: We used a worldwide electronic survey with practice-related demographic questions and clinical questions about 2 cases: (1) a 20-year-old woman with a neuropsychiatric presentation strongly suspicious of AE and (2) a 40-year-old man with new temporal lobe seizures and cognitive impairment. Responses among different groups were compared using multivariable logistic regression.

Meningoradiculitis and transaminitis from neuroborreliosis: A case of variant Bannwarth syndrome.

Background: Lyme disease is a common vector-borne illness in the U.S. caused by Borrelia species spirochetes.

Autoimmune Encephalitides and Rapidly Progressive Dementias.

Rapidly progressive dementia (RPD) or cognitive decline is a common presenting complaint in neurology. While primary dementia is often a concern, other forms of reversible dementia must be thoroughly considered. This article focuses on the growing field of autoimmune encephalitis (AE) as it pertains to the differential diagnostic considerations in a work-up for RPD.

Practice Current: When do you suspect autoimmune encephalitis and what is the role of antibody testing?

Diagnosing autoimmune encephalitis (AE) is complicated by several factors, including issues with availability, sensitivity, and specificity of antibody testing, particularly with variability in assay techniques and new antibodies being rapidly identified; nonspecific findings on MRI, EEG, and lumbar puncture; and competing differential diagnoses. Through case-based discussions with 3 experts from 3 continents, this article discusses the challenges of AE diagnosis, important clinical characteristics of AE, preferences for methods of autoantibody testing and interpretation, and treatment-related questions. In particular, we explore the following question: If a patient's clinical presentation seems consistent with AE but antibody testing is negative, can one still diagnose the patient with AE? Furthermore, what factors does one consider when making this determination, and should treatment proceed independent of antibody testing in suspected cases? The same case-based questions were posed to the rest of our readership in an online survey, the results of which are also presented.

Incidence of meningeal enhancement on brain MRI secondary to lumbar puncture.

Background: Concern for reactive meningeal enhancement after lumbar puncture (LP) is a common reason for performing brain MRI prior to LP. We sought to determine actual incidence of unexplained meningeal enhancement after LP.

Methods: We collected results from all contrasted brain MRIs in patients admitted to adult neurology at a New York City hospital over a 3-year period.
