Antiphospholipid (aPL) antibodies have historically been postulated to cause a poorly understood inflammatory myelitis. Neuromyelitis optica spectrum disorder (NMOSD) causes an inflammatory longitudinally extensive transverse myelitis (LETM). In 2004, aquaporin-4 immunoglobulin G (AQP4-IgG) was first reported as a highly specific (>99%) serum diagnostic biomarker of NMOSD, distinguishing it from other disorders (eg, multiple sclerosis). We sought to assess the frequency of AQP4-IgG (and thus NMOSD diagnosis) in LETM with aPL antibodies...

BACKGROUND: Cysticercosis (CC) is a tissue infection caused by the larval cysts of the pork tapeworm Taenia solium. It is usually acquired by eating contaminated food or drinking water. CC Cysts can develop in the muscles, the eyes, the brain, and/or the spinal cord. T. solium is found worldwide, but its prevalence has decreased in developed countries due to stricter meat inspection and better hygiene and sanitation. Nevertheless, CC is still a leading cause of seizures and epilepsy. In Spain, The disease is not nationally reportable and data on CC infected animals are also missing, despite the European Directive 2003/99/EC...

PURPOSE OF REVIEW: This article reviews bacterial, viral, fungal, and parasitic pathogens associated with myelopathy. Infectious myelopathies may be due to direct infection or parainfectious autoimmune-mediated mechanisms; this article focuses primarily on the former. RECENT FINDINGS: Some microorganisms exhibit neurotropism for the spinal cord (eg, enteroviruses such as poliovirus and flaviviruses such as West Nile virus), while others are more protean in neurologic manifestations (eg, herpesviruses such as varicella-zoster virus), and others are only rarely reported to cause myelopathy (eg, certain fungal and parasitic infections)...

PURPOSE: The purposes of this article were to evaluate the short-term outcome of plasma exchange (PLEX) for neuromyelitis optica spectrum disorders (NMOSDs) in Chinese patients and to identify the factors predictive of a favorable response to therapy. METHODS: We retrospectively analyzed data from 29 Chinese patients with NMOSD. All patients received 2 to 7 sessions of PLEX every other day. Expanded Disability Status Scale (EDSS) scores were estimated at baseline, at relapse, and before and at follow-up after PLEX...

Primary human immunodeficiency virus (HIV) neuropathologies can affect all levels of the neuraxis and occur in all stages of natural history disease. Some, like HIV encephalitis, HIV myelitis, and diffuse infiltrative lymphocytosis of peripheral nerve, reflect productive infection of the nervous system; others, like vacuolar myelopathy, distal symmetric polyneuropathy, and central and peripheral nervous system demyelination, are not clearly related to regional viral replication, and reflect more complex cascades of dysregulated host immunity and metabolic dysfunction...

The epidemiology of spinal cord disease in human immunodeficiency virus (HIV) infection is largely unknown due to a paucity of data since combination antiretroviral therapy (cART). HIV mediates spinal cord injury indirectly, by immune modulation, degeneration, or associated infections and neoplasms. The pathologies vary and range from cytotoxic necrosis to demyelination and vasculitis. Control of HIV determines the differential for all neurologic presentations in infected individuals. Primary HIV-associated acute transverse myelitis, an acute inflammatory condition with pathologic similarities to HIV encephalitis, arises in early infection and at seroconversion...

BACKGROUND: Syphilis is a sexually transmitted infection that was nearly eradicated in 2001 but is now making a resurgence. It has a wide range of clinical manifestations depending on disease stage. Neurosyphilis is an infrequently seen infectious disease with central nervous system involvement that can occur in either early- or late-stage syphilis. The diagnosis of neurosyphilis is challenging, primarily because Treponema pallidum, the infecting organism, cannot be cultured in vitro...

Increasing recognition of the role of B cells in the adaptive immune response makes B cells an important therapeutic target in autoimmunity. Numerous current and developmental immunotherapies target B cells for elimination through recognition of cell-surface proteins expressed specifically on B cells, in particular CD19 and CD20. Similarities and differences in the function and expression of these two molecules predict some shared, and some distinct, pharmacological effects of agents targeting CD19 versus CD20, potentially leading to differences in the clinical safety and efficacy of such agents...

OBJECTIVE: We conducted a systematic review to investigate the clinical value of clinical characteristics and autoantibodies, especially lupus-specific antibodies, for lupus myelitis and its subtypes. METHODS: We searched PubMed, EMBASE, and ICHUSHI without language restrictions for case reports or series of lupus myelitis. We focused on cases reported since 1997, when the revised classification criteria for systemic lupus erythematosus were published. Associations between patient characteristics including autoantibodies and functional outcome, survival, subtypes of myelitis (grey and white matter myelitis), and treatment were examined...

Enterovirus D68 (EV-D68) is a medically important respiratory plus-strand RNA virus of children that has been linked to acute flaccid myelitis. We have determined that EV-D68 induces autophagic signaling and membrane formation. Autophagy, a homeostatic degradative process that breaks down protein aggregates and damaged organelles, promotes replication of multiple plus-strand viruses. Induction of autophagic signals promotes EV-D68 replication, but the virus inhibits the downstream degradative steps of autophagy in multiple ways...

A 27-year-old woman with optic neuritis and cervical myelitis developed hypertrophic demyelinating polyneuropathy. It was hypothesized that the diagnosis was combined central and peripheral demyelination. A hypertrophic nerve was observed subcutaneously, and magnetic resonance imaging demonstrated marked hypertrophy of the nerve roots. The patient was negative for anti-aquaporin 4 antibodies. Her anti-neurofascin 155 antibody levels was slightly elevated, but it was not definitely positive. Pulsed steroid therapy and the administration of immunoglobulin ameliorated her symptoms...

Neurological manifestations associated with HHV-7 have been described in primary infection in children, and very occasionally in immunocompromised adult patients. However, the role of HHV-7 reactivation as a cause of central nervous system (CNS) diseases in immunocompetent adults has not yet been defined. We retrospectively analyzed clinical and microbiological features of adults with neurological symptoms who underwent lumbar puncture and a multiplex polymerase chain reaction (PCR) for herpesviruses (HHV-1-8) and enteroviruses performed in cerebrospinal fluid (CSF), during a 4-year period...

Zika virus (ZIKV) is a mosquito-borne virus that has been identified as a cause of several severe disease manifestations, including congenital microcephaly and Guillain-Barré syndrome, meningoencephalitis and myelitis. Previous studies showed that ZIKV-infected patients exhibited elevated plasma levels of interleukin-1β (IL-1β), indicating that ZIKV may activate inflammasomes. However, the molecular basis for its viral pathogenesis remains poorly understood. In this current study, we found that ZIKV infection caused severe inflammatory pathological changes and promoted IL-1β production in vitro as well as in vivo...

RATIONALE: Longitudinally extensive transverse myelitis (LETM) is characterized by contiguous inflammatory lesions of spinal cord extending to ≥3 vertebral segments. The etiology of LETM is complicated, including various infection, autoimmune disease, and so on. Neuromyelitis optic spectrum disorder (NMOSD) is the most common cause of LETM. Several case reports have suggested the associations between NMOSD and pulmonary tuberculosis (PTB). PATIENT CONCERNS: Patient 1, a 20-year-old woman who had a past history of PTB, presented with weakness, numbness, and pain in the limbs...
