Distal symmetric polyneuropathy (DSPN) is the most common neuropathy to occur in diabetes mellitus. However, patients with diabetes can also develop inflammatory neuropathies, the most common and most treatable of which is chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Whether diabetes is a risk factor for CIDP remains under debate. Early studies suggested that patients with diabetes were at increased risk of CIDP, but epidemiological studies failed to confirm the association, and subsequent data have re-opened the debate...

INTRODUCTION: In chronic inflammatory demyelinating polyneuropathy (CIDP), emphasis has been on motor disabilities, and autonomic dysfunction in these patients has not been addressed systematically. MATERIALS AND METHODS: Autonomic function was prospectively analyzed in 38 patients with CIDP. Quantitative autonomic function testing was done using Finometer(®) PRO and severity of adrenergic and cardiovagal dysfunction graded according to composite autonomic severity score and sudomotor dysfunction assessed using sympathetic skin response...

BACKGROUND Chronic inflammatory demyelinating polyneuropathy (CIDP) is an uncommon manifestation of systemic lupus erythematosus (SLE). We report a case of SLE presenting as CIDP and discuss the diagnosis, management, and prognosis of CIDP. CASE REPORT A 40-year-old woman with a past medical history of SLE treated with hydroxychloroquine presented with bilateral, progressive, ascending, sensory and motor neuropathy. Physical examination showed weakness and reduced temperature of all extremities, reduced pinprick and vibration sense of the distal extremities, loss of reflexes, and walking with a wide-based unsteady gait...

BACKGROUND: Subcutaneous (SC) immunoglobulin (Ig) is an effective therapy for Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP). However, optimal dosage and frequency of administration remain to be clarified. OBJECTIVES: We sought to assess the feasibility and tolerability of a novel regimen of SCIg administration, based on concentrated "bolus" doses delivered every other week, as compared to the "conventional" SCIg regimen, based on 1-3 administrations/week...

We report a 59-year-old Japanese male who developed gradually worsening weakness and numbness of distal four extremities since age 50. His parents were first cousins, and blood and cerebral spinal examinations were unremarkable. Homozygous mutation of MME gene was detected and thus he was diagnosed as autosomal-recessive Charcot-Marie-Tooth disease 2T (AR-CMT2T); however, electrophysiological examinations revealed scattered demyelinative changes including elongated terminal latency in several peripheral nerve trunks...

Treatment options for patients with aggressive chronic inflammatory demyelinating neuropathy are limited and include the anti-CD20 antibody rituximab and the immunosuppressive regime cyclophosphamide. We aimed to investigate retrospectively the efficacy of bortezomib, a proteasome inhibitor tackling highly metabolically active cell types such as plasma cells, in a case series of 10 treatment refractory CIDP patients. All patients reported showed a deterioration of the clinical CIDP scores under first-line treatment or escalating treatment with cyclophosphamide or rituximab...

AIMS/HYPOTHESIS: Type 1 diabetes is believed to be an autoimmune disease associated with irreversible loss of insulin secretory function that follows a chronic progressive course. However, it has been speculated that relapsing/remitting disease progression may occur in type 1 diabetes. METHODS: We report the case of an 18-year-old girl with Graves' disease, chronic inflammatory demyelinating polyneuropathy (CIDP) and multiple islet autoantibodies, presenting with relapsing/remitting hyperglycaemia...

Neurodegenerative disease are frequently characterized by microglia activation and/or leukocyte infiltration in the parenchyma of the central nervous system and at the molecular level by increased oxidative modifications of proteins, lipids and nucleic acids. NADPH oxidases (NOX) emerged as a novel promising class of pharmacological targets for the treatment of neurodegeneration due to their role in oxidant generation and presumably in regulating microglia activation. The unique function of NOX is the generation of superoxide anion (O2(•-)) and hydrogen peroxide (H2O2)...

INTRODUCTION: Neurofascin155 (NF155) is a target antigen for autoantibodies in a subset of chronic inflammatory demyelinating polyneuropathy (CIDP). METHODS: We report the cases of 4 patients with anti-NF155 immunoglobulin G4 (IgG4) antibody-positive CIDP who underwent sural nerve biopsies. RESULTS: All patients were relatively young at onset. Three patients experienced tremors, and 2 patients had severe ataxia. Although the response to intravenous immunoglobulin was poor in all patients, plasma exchange and corticosteroids were at least partially effective...

The objective of this study was to identify early clinical, biochemical and electrophysiological prognostic factors of disability in CIDP. We evaluated a dataset from 60 CIDP patients that included sex, age of onset, type of onset, phenotype, disease duration, response to treatment, disability at the time of diagnosis assessed using the modified Rankin Scale (baseline mRS), cerebrospinal fluid protein levels and electrophysiological data. All patients had clinical assessment of disability through the mRS within the last 6 months (last mRS) before enrollment in the study...

OBJECTIVE: Short-term efficacy of induction therapy with intravenous immunoglobulin (Ig) in patients with chronic inflammatory demyelinating polyneuropathy (CIDP) is well established. However, data of previous studies on maintenance therapy were limited up to 24-week treatment period. We aimed to investigate the efficacy and safety of longer-term intravenous Ig therapy for 52 weeks. METHODS: This study was an open-label phase 3 clinical trial conducted in 49 Japanese tertiary centres...

PURPOSE OF REVIEW: As a syndrome with typical and atypical cases, chronic inflammatory demyelinating polyneuropathy (CIDP) has been a difficult disorder to diagnose and treat. The pathophysiologic basis for CIDP has not been established, contributing to the challenges in dealing with these patients. However, as one of only a handful of treatable peripheral neuropathies, there has been a tendency to diagnose CIDP to attempt a therapeutic intervention. We are also aware that there has also been overtreatment of some patients...

The chronic inflammatory neuropathies (CINs) are rare, very disabling autoimmune disorders that generally respond well to immune therapies such as intravenous immunoglobulin (IVIg). The most common forms of CIN are chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multifocal motor neuropathy, and polyneuropathy associated with monoclonal gammopathy of unknown significance. The field of CIN has undergone a major advance with the identification of IgG4 autoantibodies directed against paranodal proteins in patients with CIDP...

BACKGROUND: Chronic immune sensory polyradiculopathy (CISP) identifies a progressive acquired peripheral dysimmune neuropathy recognized as a chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) variant. We describe a young woman with a thirteen-year history of CISP with a belated variable response to intravenous immunoglobulin (IVIG) and an almost erratic anticipation of symptoms between IVIG cycles. The association of IVIG and corticosteroids, immunosuppressants, plasmapheresis, did not lead to clinical improvement and was characterized by significant side effects...
