Neuromyelitis optica, paraneoplastic, autoimmune

Daniel C Wiener, Tamara B Kaplan, Carlos E Bravo-Iñiguez, Jordan Miller, Aaron L Berkowitz, Michael T Jaklitsch
Neuromyelitis optica spectrum disorders are a group of relapsing, inflammatory, demyelinating neurologic syndromes involving the central nervous system associated with antibodies against aquaporin-4. Although most commonly an idiopathic autoimmune condition, neuromyelitis optica may occur as a paraneoplastic syndrome in rare instances. We report a case of transverse myelitis caused by paraneoplastic neuromyelitis optica as the presenting clinical syndrome in a patient with esophageal adenocarcinoma.

BACKGROUND: Paraneoplastic syndromes are remote effects of cancer caused by an autoimmune response triggered by tumor cells. Paraneoplastic Neuromyelitis Optica Spectrum Disorders (NMOSD) has been previously described, but the underlying mechanism for these rare cases is not well characterized. This paper presents a newly described case series of paraneoplastic NMOSD, including 2 new histological types of cancer and histological validation. METHODS: The UBC NMO clinic database was surveyed and identified 6 patients with paraneoplastic NMOSD...

Neuromyelitis optica spectrum disorders (NMOSD) are demyelinating, autoimmune diseases affecting the central nervous system. Typically, recurrent optic neuritis and longitudinal extensive transverse myelitis dominates the clinical picture. In most cases NMOSD are associated with autoantibodies targeting the water channel aquaporin-4 (AQP-4). NMOSD usually present in young adults. Clinical findings suggestive of NMOSD in elderly patients should raise the suspicion of a paraneoplastic etiology. To our knowledge, we report the first case of a 66 year-old female patient with paraneoplastic NMOSD that is associated with squamous cell lung carcinoma...

Autoimmune diseases are sometimes associated with neoplasms. A 70-year-old Japanese woman with myelitis, seropositive for aquaporin-4 (AQP4) antibody, was diagnosed with neuromyelitis optica spectrum disorder (NMOSD); thereafter an esophageal squamous cell carcinoma was identified. Immunohistochemically, her cancer was anti-AQP4 antibody negative. Her symptoms, imaging findings and AQP4 titer markedly improved with corticosteroid and anti-cancer therapies. Although AQP4 may be a paraneoplastic antigen, paraneoplastic syndrome could not be definitively diagnosed in this case...

There are common aspects and mechanisms between different types of autoimmune diseases such as multiple sclerosis (MS), neuromyelitis optica spectrum disorders (NMOSDs), and autoimmune encephalitis (AE) as well as paraneoplastic inflammatory disorders of the central nervous system. To our present knowledge, depending on the disease, T and B cells as well as antibodies contribute to various aspects of the pathogenesis. Possibly the events leading to the breaking of tolerance between the different diseases are of great similarity and so far, only partially understood...

Autoimmune myelopathies are a heterogeneous group of immune-mediated spinal cord disorders with a broad differential diagnosis. They encompass myelopathies with an immune attack on the spinal cord (e.g., aquaporin-4-IgG (AQP4-IgG) seropositive neuromyelitis optica (NMO) and its spectrum disorders (NMOSD)), myelopathies occurring with systemic autoimmune disorders (which may also be due to coexisting NMO/NMOSD), paraneoplastic autoimmune myelopathies, postinfectious autoimmune myelopathies (e.g., acute disseminated encephalomyelitis), and myelopathies thought to be immune-related (e...

A number of autoantibodies, some paraneoplastic, are associated with sleep disorders. Morvan syndrome and limbic encephalitis, associated with voltage-gated potassium channel-complex antibodies, principally against CASPR2 and LGI1, can result in profound insomnia and rapid eye movement sleep behavior disorder (RBD). Patients with aquaporin-4 antibodies and neuromyelitis optica may develop narcolepsy in association with other evidence of hypothalamic dysfunction, sometimes as the initial presentation. Central sleep apnea and central neurogenic hypoventilation are found in patients with anti-N-methyl-d-aspartate receptor antibody encephalitis, and obstructive sleep apnea, stridor, and hypoventilation are prominent features of a novel tauopathy associated with IgLON5 antibodies...

BACKGROUND: There is a growing evidence for autoimmunity in acute central nervous system (CNS) disorders and treatment with therapeutic plasma exchange (TPE) may be considered. The aim was to share our experience on the clinical application of TPE in these disorders and to present a reproducible protocol which can be used even in small children. METHODS: We present a series of 8 children aged 2-12 years with transverse myelitis, Bickerstaff's brainstem encephalitis, neuromyelitis optica, and acute paraneoplastic or unspecified encephalitis in whom TPE was used as a second-line or rescue treatment...

Neuromyelitis optica (NMO) and a related spectrum of inflammatory CNS disorders are unified by detection of a serum autoantibody specific for the aquaporin-4 (AQP4) water channel, which is abundant in astrocytic foot processes. The classic clinical manifestations of NMO are optic neuritis and longitudinally extensive transverse myelitis. Newly recognized manifestations of AQP4 autoimmunity include lesions of circumventricular organs and skeletal muscle. NMO is commonly relapsing, is frequently accompanied by other autoimmune disorders, and sometimes occurs in a paraneoplastic context...

BACKGROUND: The observations of neuromyelitis optica spectrum disorders (NMOSD) occurring in the setting of cancer suggest that aquaporin-4 (AQP4) autoimmunity may in some cases be paraneoplastic. RESULTS: We describe a 72-year-old patient who developed a longitudinally extensive transverse myelitis associated with AQP4 autoantibodies in the setting of a lung adenocarcinoma recurrence. AQP4 expression was demonstrated in tumor cells. IgG in patient's cerebrospinal fluid bound to tumor cells co-localizing with AQP4 immunoreactivity...

Rituximab is a chimeric murine/human monoclonal antibody that specifically targets CD20 molecules on the surface of B-cells, thereby depleting B-cells and regulating humoral immunity. This antibody is mostly used in CD20-positive B-cell lymphoma, but is also widely used in many other connective tissue and neurological disorders. These neurological disorders include multiple sclerosis, neuromyelitis optica, myasthenia gravis, Lambert-Eaton myasthenic syndrome, chronic inflammatory demyelinating polyradiculoneuropathy, paraneoplastic neurological syndromes, primary central nervous system lymphoma, inflammatory myopathy, and some other autoimmune-mediated neurological disorders...

Neuromyelitis optica (NMO), or Devic's syndrome, is an autoimmune central nervous system demyelinating disorder primarily affecting the spinal cord and the optic nerves. It is characterized by the presence of NMO antibodies, alongside clinical and radiological findings. NMO and NMO-spectrum disorders (NMO-SD) have been reported in autoimmune disorders, and are infrequently described as a paraneoplastic syndrome with cancers of lung, breast, and carcinoid tumors of the thyroid. We report a patient who presented with severe vomiting, blurring of vision, vertigo, diplopia, left hemiparesis and hemisensory loss and ataxia...

IMPORTANCE: Reports of neuromyelitis optica spectrum disorder (NMOSD) occurring in the setting of neoplasia suggest that aquaporin-4 autoimmunity may in some cases have a paraneoplastic basis. OBSERVATIONS: In this case report, we describe a patient with NMOSD whose test results were seropositive for aquaporin-4 IgG and who had a hepatic metastasis from a small-bowel neuroendocrine tumor. The tumor cells expressed aquaporin-4 immunoreactivity. She presented to the Neurology Department at Wayne State University with bilateral leg weakness, ascending paresthesias, and decreased sensation...

Neuromyelitis optica (NMO) is an immune-mediated neurological disorder characterised by recurrent episodes of optic neuritis and longitudinally extensive transverse myelitis. A serum biomarker, aquaporin-4 IgG, the autoantibody against aquaporin-4 water channel, has been specifically associated with NMO and has assisted early recognition and prediction of relapses. Less commonly, a monophasic course, associated with antibodies to myelin oligodendrocyte glycoprotein has been reported. Specific diagnostic criteria have been defined; however, some cases that do not fulfil these criteria (but are nevertheless associated with aquaporin-4 IgG) are classified as NMO spectrum disorder and follow the same relapsing course...

Autoantibodies to neuronal tissue are becoming increasingly more important in the evaluation and classification of several neurological diseases, e.g. neuromyelitis optica, paraneoplastic syndromes of the central nervous system (CNS), stiff person syndrome or autoimmune epilepsy. As these disorders are rare, no evidence-based recommendations for therapy are available. Currently, immunomodulating or immunosuppressive drugs are administered in most cases. In paraneoplastic syndromes treatment of the underlying cancer is of considerable importance...

The differential diagnosis of inflammatory myelopathies is broad. Autoimmune myelopathies represent a heterogeneous but significant portion of inflammatory myelopathies. The discovery of serologic biomarkers of autoimmune myelopathies (including aquaporin-4 and collapsin response-mediator protein-5 [CRMP-5] immunoglobulin [Ig]Gs) supports the concept of an autoimmune attack targeting the spinal cord. Neuroimaging, in particular MRI, may reveal distinctive patterns of signal abnormality suggesting an autoimmune etiology, such as longitudinally extensive transverse myelitis in neuromyelitis optica spectrum disorders or tract-specific changes in paraneoplastic disorders...

Therapeutic plasmapheresis (TPE) has an established role in disorders of the peripheral nervous system, but its use in disorders of the central nervous system (CNS) does not rely upon evidence-based data. Nevertheless, TPE is currently used in severe acute forms of demyelinating disease (multiple sclerosis/acute encephalomyelitis) unresponsive to corticosteroids. Recently, antibodies against the water channel aquaporin-4 have been detected in patients affected by neuromyelitis optica (Devic syndrome) and their pathogenetic role has been demonstrated, supporting the use of TPE in this disease...
