Brain Nerve 2019 Feb;71(2):167-174

Department of Neurology and Strokology, Nagasaki University Hospital.

A 63-year-old female who developed dizziness, diplopia and subsequent gait disturbance from September X-1 year was analyzed. The first neurological findings in May X year revealed cerebellar ataxia, weakness in the proximal limbs, decreased tendon reflexes, and autonomic symptoms (ADL:mRS 3). Furthermore, an incremental phenomenon was observed in the repetitive nerve stimulation test, and she was diagnosed with Lambert-Eaton myasthenic syndrome (LEMS) based on the serum P/Q-type calcium channel (VGCC) antibody positivity.

Glutamate Receptor Antibodies in Autoimmune Central Nervous System Disease: Basic Mechanisms, Clinical Features, and Antibody Detection.

Methods Mol Biol 2019 ;1941:225-255

Department of Neurology, University Hospitals Birmingham NHS Foundation Trust, Birmingham, UK.

Immune-mediated inflammation of the brain has been recognized for more than 50 years, although the initial descriptions were mainly thought to be secondary to an underlying neoplasm. Some of these paraneoplastic encephalitides express serum antibodies, but these were not thought to be pathogenic but instead have a T-cell-mediated pathophysiology. Over the last two decades, several pathogenic antibodies against neuronal surface antigens have been described in autoimmune encephalitis, which are amenable to immunotherapy. Read More

Anti-Yo antibody-mediated paraneoplastic cerebellar degeneration associated with cognitive affective syndrome in a patient with breast cancer: a case report and literature review.

Authors:
M Le May S Dent

Curr Oncol 2018 Dec 1;25(6):e585-e591. Epub 2018 Dec 1.

Department of Medicine, Division of Medical Oncology, University of Ottawa, Ottawa, ON.

Breast cancer is the most common cancer in women, with 15%-25% of those tumours overexpressing the human epidermal growth factor receptor 2 (her2), which is associated with more aggressive disease. On rare occasions, patients present with a paraneoplastic syndrome months to years before their cancer diagnosis. Paraneoplastic cerebellar degeneration (pcd) is associated with fewer than 1% of cancers and is strongly associated with breast and gynecologic malignancies. Read More

Paraneoplastic Cerebellar Degeneration Associated With Ovarian Adenocarcinoma: A Case Report and Review of Literature.

Ann Indian Acad Neurol 2018 Oct-Dec;21(4):311-314

Department of Neurosciences, Institute of Neurosciences/Internal Medicine, Indraprastha Apollo Hospitals, New Delhi, India.

Paraneoplastic syndromes are a rare heterogeneous group of disorders that are indicators of the underlying occult malignancy. Subacute cerebellar ataxia in a patient with a known cancer is often due to metastatic invasion or other complications of the cancer, such as infection, coagulopathy, metabolic and nutritional deficits, or side effects of treatment. When tumor- and treatment-related causes have been excluded, the patient is considered to suffer from paraneoplastic cerebellar degeneration (PCD). Read More

The utility of anti-SOX2 antibodies for cancer prediction in patients with paraneoplastic neurological disorders.

J Neuroimmunol 2019 Jan 8;326:14-18. Epub 2018 Nov 8.

Department of Pathology, Nottingham University Hospitals NHS Trust, Queen's Medical Centre, Nottingham NG7 2UH, UK.

Antibodies to SOXB1 proteins in patients with paraneoplastic disorders are associated with small-cell lung cancer (SCLC), particularly in Lambert-Eaton myasthenic syndrome (LEMS). We aimed to establish if SOX2 antibodies could be used to identify SCLC and other tumours found in a range of paraneoplastic disorders and controls. SOX2 antibodies were detectable in 61% of patients with LEMS-SCLC, and in other paraneoplastic disorders, such as opsoclonus-myoclonus and paraneoplastic cerebellar degeneration, only when there was an underlying SCLC.

Updates in the Diagnosis and Treatment of Paraneoplastic Neurologic Syndromes.

Curr Oncol Rep 2018 Nov 10;20(11):92. Epub 2018 Nov 10.

Neurology Division, Hospital das Clínicas, University of São Paulo School of Medicine, Sao Paulo, Brazil.

The disorders of the central nervous system associated with cancer by remote immune-mediated mechanisms are a heterogeneous group. These disorders encompass the classic paraneoplastic disorders and the recently recognized autoimmune encephalitis associated with antibodies against neuronal cell surface or synaptic proteins that occur with or without cancer association. In the last decade, the new surge of interest in neuronal diseases associated with anti-neuronal antibodies led to the rapid discovery of new forms of disease that have different manifestations and were not previously suspected to be immune mediated.

This chapter summarizes the neuropathologic features of nonneoplastic disorders of the adult cerebellum. Gait ataxia and extremity dysmetria are clinical manifestations of diseases that interrupt the complex cerebellar circuitry between the neurons of the cerebellar cortex, the cerebellar nuclei (especially the dentate nuclei), and the inferior olivary nuclei. The cerebellum is a prominent target of several sporadic and hereditary neurodegenerative diseases, including multiple system atrophy, spinocerebellar ataxia, and Friedreich ataxia. Read More

Transcriptomic immune profiling of ovarian cancers in paraneoplastic cerebellar degeneration associated with anti-Yo antibodies.

Br J Cancer 2018 Jul 14;119(1):105-113. Epub 2018 Jun 14.

Brain and Spine Institute (ICM), Experimental Neuro-Oncology Department, Inserm U 1127, CNRS UMR 7225, Sorbonne Universités, UPMC Univ Paris 06, 75013, Paris, France.

Background: Paraneoplastic neurological syndromes are rare conditions where an autoimmune reaction against the nervous system appears in patients suffering from a tumour, but not linked to the spreading of the tumour. A break in the immune tolerance is thought to be the trigger.

Methods: The transcriptomic profile of 12 ovarian tumours (OT) from patients suffering from paraneoplastic cerebellar degeneration (PCD) linked to anti-Yo antibodies (anti-Yo PCD OT) was compared with 733 ovarian tumours (OT control) from different public databases using linear model analysis.

Paraneoplastic cerebellar degeneration: Yo antibody alters mitochondrial calcium buffering capacity.

Neuropathol Appl Neurobiol 2018 Apr 21. Epub 2018 Apr 21.

Department of Neurology, Haukeland University Hospital, Bergen, Norway.

Aim: Neurodegeneration is associated with dysfunction of calcium buffering capacity and thereby sustained cellular and mitochondrial calcium overload. Paraneoplastic cerebellar degeneration (PCD), characterized by progressive Purkinje neurone degeneration following paraneoplastic Yo antibody internalization and binding to cerebellar degeneration-related protein CDR2 and CDR2L, has been linked to intracellular calcium homeostasis imbalance due to calbindin D malfunction. Therefore, we hypothesized that Yo antibody internalization affects not only calbindin calcium binding capacity, but also calcium-sensitive mitochondrial-associated signalling, causing mitochondrial calcium overload and thereby Purkinje neurone death.

Department of Neurochemistry and Neuropathology, Poznan University of Medical Sciences, 49, Przybyszewskiego Str., 60355 Poznan, Poland.

Paraneoplastic movement disorders are rare, autoimmune-mediated, nonmetastatic complications of malignant neoplasms. Common paraneoplastic movement disorders include paraneoplastic chorea, dystonia, cerebellar degeneration, different types of encephalitis, opsoclonus-myoclonus syndrome, stiff person syndrome, and neuromyotonia. Syndromes usually develop before tumor diagnosis, have subacute onset, and are associated with serum or cerebrospinal fluid antibodies. Read More

Time Is Cerebellum.

Cerebellum 2018 Aug;17(4):387-391

School of Medicine, University of Washington, Seattle, WA, 98109, USA.

The cerebellum characteristically has the capacity to compensate for and restore lost functions. These compensatory/restorative properties are explained by an abundant synaptic plasticity and the convergence of multimodal central and peripheral signals. In addition, extra-cerebellar structures contribute also to the recovery after a cerebellar injury. Read More

[Paraneoplastic neurological syndromes : A current summary].

Internist (Berl) 2018 Feb;59(2):151-158

Klinisches Institut für Neurologie, Medizinische Universität Wien, Währinger Gürtel 18-20, 1090, Wien, Österreich.

Background: Paraneoplastic neurological syndromes (PNNS) are remote effects of a tumor and mediated by an altered immune reaction. In the last ten years, the spectrum of PNNS has changed profoundly with the discovery of a new category of neurological diseases that are associated with antibodies against surface or synaptic antigens. In contrast to classical PNNS, patients with surface receptor autoimmunity are often highly responsive to immunotherapy. Read More

Genetic alterations and tumor immune attack in Yo paraneoplastic cerebellar degeneration.

Acta Neuropathol 2018 Apr 3;135(4):569-579. Epub 2018 Jan 3.

Institut NeuroMyogène, Equipe Synaptopathies et Autoanticorps (SynatAc), INSERM U1217/UMR CRS 5310, Lyon, France.

Paraneoplastic cerebellar degenerations with anti-Yo antibodies (Yo-PCD) are rare syndromes caused by an auto-immune response against neuronal antigens (Ags) expressed by tumor cells. However, the mechanisms responsible for such immune tolerance breakdown are unknown. We characterized 26 ovarian carcinomas associated with Yo-PCD for their tumor immune contexture and genetic status of the 2 onconeural Yo-Ags, CDR2 and CDR2L. Read More

Advances in Therapies of Cerebellar Disorders: Immune-mediated Ataxias.

CNS Neurol Disord Drug Targets 2017 Dec 20. Epub 2017 Dec 20.

Royal Hallamshire Hospital. United Kingdom.

The identification of an increasing number of immune mediated ataxias suggests that the cerebellum is often a target organ for autoimmune insults. The diagnosis of immune mediated ataxias remains challenging as there is significant clinical overlap between immune mediated and other forms of ataxia. Furthermore the classification of immune mediated ataxias requires further clarification particularly for those ataxias where no specific antigenic trigger and associated antibodies have been identified.

Paraneoplastic cerebellar syndromes associated with antibodies against Purkinje cells.

Int J Neurosci 2018 Aug 18;128(8):721-728. Epub 2017 Dec 18.

a Clinical Neuroimmunology and Neurochemistry, Department of Neurology , Hannover Medical School , Hannover , Germany.

The paraneoplastic cerebellar syndrome presents as severe neuroimmunological disease associated with malignancies. Antibodies against antigens expressed by tumor cells cross-react with proteins of cerebellar Purkinje cells leading to neuroinflammation and neuronal loss. These antineuronal antibodies are preferentially investigated by serological analyses while examination of the cerebrospinal fluid is only performed infrequently. Read More

T cells presenting viral antigens or autoantigens induce cytotoxic T cell anergy.

JCI Insight 2017 Nov 2;2(21). Epub 2017 Nov 2.

Laboratory of Molecular Neuro-Oncology, The Rockefeller University, New York, New York, USA.

In the course of modeling the naturally occurring tumor immunity seen in patients with paraneoplastic cerebellar degeneration (PCD), we discovered an unexpectedly high threshold for breaking CD8+ cytotoxic T cell (CTL) tolerance to the PCD autoantigen, CDR2. While CDR2 expression was previously found to be strictly restricted to immune-privileged cells (cerebellum, testes, and tumors), unexpectedly we have found that T cells also express CDR2. This expression underlies inhibition of CTL activation; CTLs that respond to epithelial cells expressing CDR2 fail to respond to T cells expressing CDR2. Read More
