FTY720 controls disease severity and attenuates sciatic nerve damage in chronic experimental autoimmune neuritis.

J Neuroinflammation 2019 Mar 2;16(1):54. Epub 2019 Mar 2.

Biopathologie de la Myéline, Neuroprotection et Stratégies Thérapeutiques, INSERM U1119/Université de Strasbourg, Faculté de Médecine, 11 rue Humann, 67085, Strasbourg, France.

Background: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an autoimmune-mediated inflammatory disease of the peripheral nervous system characterized by a response directed against certain myelin proteins and for which therapies are limited. Previous studies have suggested a beneficial role of FTY720, a sphingosine 1-phosphate (S1P) receptor agonist, known to deplete lymphocytes from the peripheral blood by sequestering them into lymph nodes, in the treatment of experimental autoimmune neuritis (EAN). Therefore, we investigated whether FTY720 is also beneficial in chronic experimental autoimmune neuritis (c-EAN), a recently developed rat model mimicking human CIDP. Read More

Anti-neurofascin autoantibody and demyelination.

Neurochem Int 2018 Dec 22. Epub 2018 Dec 22.

Department of Neurology, Neurological Institute, Graduate School of Medical Sciences, Kyushu University, 3-1-1 Maidashi, Higashi-ku, Fukuoka, 812-8582, Japan.

Demyelination diseases involving the central and peripheral nervous systems are etiologically heterogeneous with both cell-mediated and humoral immunities playing pathogenic roles. Recently, autoantibodies against nodal and paranodal proteins, such as neurofascin186 (NF186), neurofascin155 (NF155), contactin-1 (CNTN1), contactin-associated protein 1 (CASPR1) and gliomedin, have been discovered in not only chronic demyelinating conditions, such as multiple sclerosis (MS) and chronic inflammatory demyelinating polyradiculoneuropathy, but also in acute demyelinating conditions, such as Guillain-Barré syndrome. Only a minority of these patients harbor anti-nodal/paranodal protein antibodies; however, these autoantibodies, especially IgG4 subclass autoantibodies to paranodal proteins, are associated with unique features and these conditions are collectively termed nodopathy or paranodopathy.

Presence of both anti-contactin 1 and anti-neurofascin 140 antibodies in a case of chronic inflammatory demyelinating polyneuropathy.

eNeurologicalSci 2018 Dec 22;13:38-39. Epub 2018 Nov 22.

Department of Neurology, University of Florida, Gainesville, FL 32610, United States.

Chronic inflammatory demyelinating polyneuropathy (CIDP) is an acquired disorder of peripheral nerves and nerve roots. Its cause is unknown, but recently antibodies to nodal and paranodal proteins have been discovered in a small subset of CIDP patients. These contactin and neurofascin-related immune-mediated neuropathies are thought to be variants of CIDP and often respond suboptimally to standard therapy. Read More

Background: It was previously reported that high salt dietary conditions can drive autoimmunity and worsen severity and symptoms of autoimmune diseases. Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a common autoimmune condition of the peripheral nervous system which leads to progressive paralysis and sensory deficits due to a demyelination and secondary axonal loss of peripheral nerves. We used a previously described model with a knockout of CD86 in non-obese diabetic mice (CD86 NOD), which results in the spontaneous development of an autoimmune peripheral neuropathy similar to CIDP and investigated the influence of a high salt diet on functional impairment, electrophysiological parameters, demyelination and neuroinflammation in these mice.

Immune-mediated neuropathies.

Nat Rev Dis Primers 2018 Oct 11;4(1):31. Epub 2018 Oct 11.

Department of Neurology, Medical Faculty, Heinrich Heine University, Düsseldorf, Germany.

Since the discovery of an acute monophasic paralysis, later coined Guillain-Barré syndrome, almost 100 years ago, and the discovery of chronic, steroid-responsive polyneuropathy 50 years ago, the spectrum of immune-mediated polyneuropathies has broadened, with various subtypes continuing to be identified, including chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and multifocal motor neuropathy (MMN). In general, these disorders are speculated to be caused by autoimmunity to proteins located at the node of Ranvier or components of myelin of peripheral nerves, although disease-associated autoantibodies have not been identified for all disorders. Owing to the numerous subtypes of the immune-mediated neuropathies, making the right diagnosis in daily clinical practice is complicated. Read More

Functioning and quality of life in patients with neuropathy associated with anti-MAG antibodies.

J Neurol 2018 Dec 10;265(12):2927-2933. Epub 2018 Oct 10.

Division of Neuroscience, Department of Neurology, Institute of Experimental Neurology (INSPE), IRCCS San Raffaele Scientific Institute, Milan, Italy.

Although anti-myelin-associated glycoprotein (MAG) antibody neuropathy is reported as a slowly progressive disease, it can lead to significant disability and impairment of health-related quality of life (HR-QoL) and social participation. The aim of this cross-sectional study was to evaluate the functioning and HR-QoL determinants in 67 patients with anti-MAG neuropathy in terms of the International Classification of Functioning, Disability, and Health (ICF). Evaluations included: Medical Research Council (MRC) sum score, Sensory Modality Sum score (SMS), Berg balance scale (BBS), Fatigue Severity Scale (FSS), Visual Analogue Scale (VAS) for pain, 9-Hole Peg Test (9-HPT), 6-min Walk Distance (6MWD), Impact on Participation and Autonomy (IPA) and the physical component score (PCS) and mental component score (MCS) of the short-form-36 health status scale (SF-36) HR-QoL measure.

Short-term and long-term effects of immunoadsorption in refractory chronic inflammatory demyelinating polyneuropathy: a prospective study in 17 patients.

J Neurol 2018 Dec 6;265(12):2906-2915. Epub 2018 Oct 6.

Universitätsklinik Ulm, RKU, Oberer Eselsberg 45, 89081, Ulm, Germany.

Objective: Chronic inflammatory demyelinating polyneuropathy (CIDP) is a rare, autoimmune-inflammatory disease of the peripheral nervous system. Recently, various immunoglobulin G4 (IgG4) type auto-antibodies have been described in patients with CIDP which can effectively be removed by immunoadsorption (IA). Therefore, we prospectively evaluated the therapeutic effect of IA in 17 patients with progressive CIDP not responding to other treatment. Read More

Proposal of new clinical diagnostic criteria for POEMS syndrome.

J Neurol Neurosurg Psychiatry 2019 Feb 2;90(2):133-137. Epub 2018 Oct 2.

Department of Neurology, Graduate School of Medicine, Chiba University, Chiba, Japan

Objective: To propose the optimal diagnostic criteria for polyneuropathy, organomegaly, endocrinopathy, M-protein and skin changes (POEMS) syndrome using appropriate statistical methods and disease controls.

Methods: This retrospective cohort study included 104 consecutive patients with suspected POEMS syndrome, among whom a gold standard group of 60 patients with definitive POEMS syndrome diagnosis were followed for at least 12 months to strictly exclude other disorders mimicking POEMS syndrome and to confirm response to POEMS syndrome-specific treatment. Thirty patients with chronic inflammatory demyelinating polyradiculoneuropathy (demyelinating polyradiculoneuropathy controls) and 30 with multiple myeloma or immunoglobulin light chain amyloidosis (monoclonal plasma cell proliferation controls) were also included.

Rituximab in chronic inflammatory demyelinating polyradiculoneuropathy with associated diseases.

J Peripher Nerv Syst 2018 Dec 7;23(4):235-240. Epub 2018 Oct 7.

Department of Clinical Neurophysiology, APHP, Pitié-Salpêtrière Hospital, Paris, France.

We aimed to analyse the response to rituximab in a cohort of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) patients with associated disorders. We conducted a clinical and electrophysiological retrospective monocentric study in 28 CIDP patients. Response to rituximab was defined as (a) a five-point increase in the Medical Research Council sum score or a one-point decrease in the Overall Neuropathy Limitations Scale score, compared to the score at the first rituximab infusion, or (b) the discontinuation of, or reduced need for, the last treatments before rituximab initiation.
