INTRODUCTION: Chronic inflammatory demyelinating polyneuropathy (CIDP) is an acquired autoimmune disorder with progressive weakness. Acute-onset CIDP resembles Guillain-Barre syndrome (GBS), a rapidly progressive disorder, and follows a chronic course. To our knowledge, no case of acute-onset CIDP in hantavirus and hepatitis B virus (HBV) coinfection has been reported previously. CLINICAL FINDINGS: We report a case of acute-onset CIDP that was initially diagnosed as GBS...

BACKGROUND: Chronic inflammatory demyelinating polyneuropathy (CIDP) is treated with intravenous immunoglobulins (IVIg), corticosteroids or plasma exchange (PE). IVIg dosage is not universal and markers for treatment management are needed. METHODS: We report the response to high-dose and fractioned IVIg in a subgroup of definite CIDP patients, resistant to corticosteroids and PE, responders to IVIg but with an efficacy window <15 days. RESULTS: Four patients were included with similar predominantly clinical motor form and conduction abnormalities...

Autoantibodies in chronic demyelinating neuropathies have been explored for several years. Recently, the peptides in the nodes of Ranvier have been the focus of attention in finding targets of autoantibodies. Until now, the most popular autoantibodies have been contactin-1 and neurofascin-155 for chronic demyelinating polyradiculoneuropathy (CIDP), GM1-ganglioside for multifocal motor neuropathy, and myelin-associated glycoprotein for polyneuropathy associated with monoclonal gammopathy of unknown significance...

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired immune-mediated disorder characterized by weakness and sensory deficits that can lead to significant neurological disability. The diagnosis is based on a combination of clinical examination findings, electrodiagnostic studies, and other supportive evidence. Recognizing CIDP and distinguishing it from other chronic polyneuropathies is important because many patients with CIDP are highly responsive to treatment with immunosuppressive or immunomodulatory therapies...

Ultrasound of the nerves is an additive diagnostic tool to evaluate polyneuropathy. Recently, the need for standardized scoring systems has widely been discussed; different scores are described so far. Therefore, 327 patients with polyneuropathy were analyzed by ultrasound in our laboratory. Consequently, several ultrasound scoring tools were applied, i.e., the nerve pattern classification according to Padua et al. in all patients with CIDP and variants, the Bochum ultrasound score (BUS) and the neuritis ultrasound protocol in immune-mediated neuritis, the ultrasound pattern sum score, the homogeneity score, and the nerve enlargement distribution score in all neuropathies if possible...

REVIEW
E Delmont
Over the last five years, the management of peripheral neuropathies has become structured by the publication of recognized diagnostic criteria for inflammatory neuropathies and the elaboration of a function score, the R-ODS, used to evaluate the progression of these neuropathies. The concept of nodo-paranodopathy has enriched the concept of peripheral neuropathies, over-riding the classical mechanisms of axonal and demyelinating mechanisms. The structures of the nodes of Ranvier, gangliosides, contractin and neurofascin are preferential targets for auto-antibodies responsible for dysimmune neuropathies...

Acute inflammatory demyelinating polyneuropathy (AIDP) is an aggressive antibody- and T cell-mediated variant of Guillain-Barré Syndrome (GBS), a prominent and debilitating autoimmune disorder of the peripheral nervous system. Despite advancements in clinical management, treatment of patients with AIDP/GBS and its chronic variant CIDP remains palliative and relies on the use of non-specific immune-modulating therapies. Our laboratory has previously reported that therapeutic administration of statins safely attenuates the clinical severity of experimental autoimmune neuritis (EAN), a well-characterized animal model of AIDP/GBS, by restricting the migration of autoreactive leukocytes across peripheral nerve microvascular endoneurial endothelial cells (PNMECs) that form the blood-nerve barrier...

We aimed to validate the diagnostic utility of enzyme-linked immunosorbent assay (ELISA) for the detection of anti-neurofascin (NF) 155 antibody in 191 patients with chronic inflammatory demyelinating polyneuropathy (CIDP). Human NF155-based ELISA clearly distinguished between anti-NF155 antibody-positive and -negative sera. Fifteen CIDP patients (8%) were IgG4 anti-human NF155 antibody-positive, which were confirmed by western blot, cell-based assay and immunohistochemical study. None of disease controls or healthy subjects had positive results...

We performed a serological investigation using glycoarray in Guillain-Barré syndrome (GBS), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), and multifocal motor neuropathy (MMN). Antibodies to 10 glycolipids and 45 glycolipid complexes were tested. Anti-GM1/sulfatide and anti-GA1/sulfatide IgG antibodies were common in GBS (20.0% and 19.0%, respectively). Anti-GQ1b/sulfatide IgG antibody was detected in 14.0% of GBS patients. IgG antibodies to antigens containing GQ1b were significantly correlated with ophthalmoplegia in GBS (p<0...

Demyelinating disorders are very common, but remains isolated to the part of nervous system they involve. However, infrequently, combined involvement of central and peripheral nervous system with demyelinating process have been described. We report one such rare case, with possible theories of common etiological basis. We present a middle aged male patient with Chronic Inflammatory Demyelinating Polyneuropathy(CIDP), who responded to immuno-modulation. Subsequently, he developed Acute Transverse Myelitis (ATM)...

The objective of this study is to determine if the nerve pathology in patients with POEMS syndrome is different from CIDP. We hypothesized that nerve biopsies from patients with POEMS syndrome would have more small vessels and axonal degeneration but less inflammation than CIDP.We performed a retrospective analysis of nerve biopsies performed on "classic" CIDP and POEMS cases. Nerve biopsies were blinded and reviewed by two of the authors (EAP, PJBD). Teased fibers, paraffin-embedded sections, semithin sections and immunostains were analyzed...

Chronic inflammatory demyelinating neuropathy, a treatable immune-mediated disease of the peripheral nervous system is less common in childhood compared to adults. Despite different sets of diagnostic criteria, lack of a reliable biologic marker leads to challenges in diagnosis, follow-up and treatment. Our first aim was to review clinical presentation, course, response to treatment, and prognosis in our childhood patients. We also aimed to document diagnostic and therapeutic pitfalls and challenges at the bedside...

INTRODUCTION: In chronic inflammatory demyelinating polyradiculopathy (CIDP) the impairment of unmyelinated nerve fibers appears unexpected. The measurement of the electrically induced axon flare reflex is a clinical test to assess the peripheral C-nociceptor function. In this study we compared the flare area in patients suffering from chronic inflammatory demyelinating polyradiculopathy with healthy subjects. MATERIALS AND METHODS: We examined 18 patients fulfilling the criteria for CIDP (11 male, mean age 51...

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a disabling autoimmune disorder of the peripheral nervous system (PNS). Intravenous immunoglobulins (IVIg) are effective in CIDP, but the treatment response varies greatly between individual patients. Understanding this interindividual variability and predicting the response to IVIg constitute major clinical challenges in CIDP. We previously established intercellular adhesion molecule (ICAM)-1 deficient non-obese diabetic (NOD) mice as a novel animal model of CIDP...

This report concerns a case of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) with frequent treatment-dependent relapses. A 75-year-old male presented with a 2-month history of progressive weakness of the limbs with no sensory symptoms. Neurological examination revealed normal cranial nerves, MRC grade 4 power in the proximal and distal muscles of the limbs, and generalized areflexia. However, the sensory examination results, serum immunoelectrophoresis, anti-HIV antibody, and vitamins B1 and B12 levels were normal...

We report the case of a 42-year-old man with chronic hepatitis B virus infection who developed weakness and paresthesia in the extremities 2 months after administration of pegylated interferon (Peg-IFN)α-2a. Nerve conduction studies conducted 6 months after onset showed abnormal temporal dispersions in both tibial nerves. We diagnosed chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) resulting from treatment with Peg-IFNα-2a. Neurological symptoms were prolonged despite suspension of the treatment...

BACKGROUND: Chronic inflammatory demyelinating polyneuropathy (CIDP) is often associated with chronic disability, which can be accounted to incomplete regeneration of injured axons. We hypothesized that Schwann cell support for regenerating axons may be altered in CIDP, which may account for the poor clinical recovery seen in many patients. METHODS: We exposed human and rodent Schwann cells to sera from CIDP patients and controls. In a model of chronic nerve denervation, we transplanted these conditioned Schwann cells intraneurally and assessed their capacity to support axonal regeneration by electrophysiology and morphometry...
