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...

INTRODUCTION: Chediak-Higashi syndrome (CHS) is a very rare autosomal recessive disorder (gene CHS1/LYST) characterized by partial albinism, recurrent infections, and easy bruising. Survivors develop a constellation of slowly progressive neurological manifestations. METHODS: We describe clinical, laboratory, electrophysiological, and genetic findings of a patient who developed an immune-mediated demyelinating neuropathy as the main clinical feature of CHS. RESULTS: The patient presented with subacute flaccid paraparesis, absent reflexes, and reduced vibration sense...

INTRODUCTION: High-dose intravenous immunoglobulin (IVIg) is an evidence-based treatment for multifocal motor neuropathy (MMN) and chronic inflammatory demyelinating polyneuropathy (CIDP). Recently, subcutaneous immunoglobulin (SC-Ig) has received increasing attention. METHODS: We performed a meta-analysis of reports of efficacy and safety of SC-Ig versus IVIg for inflammatory demyelinating polyneuropathies. RESULTS: A total of 8 studies comprising 138 patients (50 with MMN and 88 with chronic CIDP) were included in the meta-analysis...

Chronic inflammatory demyelinating polyneuropathy (CIDP) is the most common chronic autoimmune neuropathy. While both cell-mediated and humoral mechanisms contribute to its pathogenesis, the rapid clinical response to plasmapheresis implicates a circulating factor responsible for peripheral nerve injury. We report that treatment-naïve patients with CIDP show increased serum and CSF levels of the anaphylatoxin C5a and the soluble terminal complement complex (sTCC). Systemic terminal complement activation correlates with clinical disease severity as determined by the Inflammatory Neuropathy Cause and Treatment (INCAT) disability scale...

Peripheral neuropathies are diseases of the peripheral nervous system that can be divided into mononeuropathies, multifocal neuropathies, and polyneuropathies. Symptoms usually include numbness and paresthesia. These symptoms are often accompanied by weakness and can be painful. Polyneuropathies can be divided into axonal and demyelinating forms, which is important for diagnostic reasons. Most peripheral neuropathies develop over months or years, but some are rapidly progressive. Some patients only suffer from mild, unilateral, slowly progressive tingling in the fingers due to median nerve compression in the wrist (carpal tunnel syndrome), while other patients can be tetraplegic, with respiratory insufficiency within 1-2 days due to Guillain-Barré syndrome...

BACKGROUND: Monoclonal gammopathy of undeterminated significance is the most common form of plasma cell dyscrasia, usually considered as benign. In rare cases it may have a malignant course, sometimes limited to an organ such as peripheral nerves. METHODS: We describe clinical, electrophysiological and pathological findings in a patient presenting a immunoglobulin G (IgG) paraproteinemic polyneuropathy clinically mimicking a chronic inflammatory demyelinating polyneuropathy...

A 17-year-old male with no medical history noticed weakness of his limbs with imbalance and subsequent finger tremors. Physical examination revealed features of polyneuropathy, including diffuse weakness, distal symmetrical numbness with impaired deep sensation and areflexia in all limbs. Postural tremor was present in fingers. Ataxia was apparent in both lower limbs, causing a wide-based gait with a positive Romberg sign. Cerebrospinal fluid contained elevated total protein without pleocytosis. A nerve conduction study disclosed demyelinating features with prolonged terminal latencies, slow velocities with delayed F-wave latencies, and prominent temporal dispersion...

OBJECTIVE: To characterize changes in motor nerve conduction studies (MNCS) and motor unit number index (MUNIX) following treatment with subcutaneous immunoglobulin and to assess whether these changes are related to muscle strength. METHODS: Data from 23 patients participating in a randomized, controlled trial were analyzed. MNCS and MUNIX were performed before and after 12 weeks of treatment. Isokinetic strength (IMS) was measured in various muscles together with grip strength (GS)...

INTRODUCTION: To visualize peripheral nerves in patients with chronic inflammatory demyelinating polyneuropathy (CIDP), we used magnetic resonance (MR) imaging. We also quantified the volumes of the brachial and lumbar plexus and their nerve roots. METHODS: Thirteen patients with CIDP and 12 healthy volunteers were enrolled. Whole-body MR neurography based on diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) was performed. Peripheral nerve volumes were calculated from serial axial MR images...

The Guillain-Barré syndrome (GBS) and chronic inflammatory demyelinating polyneuropathy (CIDP) are the most common immune-mediated polyneuropathies, which can show variable clinical and electrophysiological manifestations. Rarer immune-mediated neuropathies encompass paraproteinemic neuropathies (PPN), multifocal motor neuropathy (MMN) and vasculitic neuropathies. The diagnosis usually relies on the history of symptom evolution, distribution of nerve dysfunction and particularly on characteristic features in nerve conduction studies, aided by cerebrospinal fluid (CSF) examination and nerve biopsy findings...

INTRODUCTION: We investigated the relationships between anti-ganglioside antibodies and Guillain-Barré syndrome (GBS) and chronic inflammatory demyelinating polyneuropathy (CIDP). METHODS: Samples from 48 patients diagnosed with GBS and 18 patients diagnosed with CIDP were retrospectively reviewed in China. RESULTS: In GBS patients, 62.5% were classified as having acute inflammatory demyelinating polyneuropathy (AIDP), 27.1% were found to have acute motor axonal neuropathy (AMAN), and 10...

INTRODUCTION: Nerve enlargement (NE) is described in inflammatory and inherited neuropathies. It is commonly multifocal and moderate in the former and homogeneous and generalized in the latter. We describe 4 cases of massive NE in inflammatory neuropathies. METHODS: Patients presented with symptoms of polyneuropathy that progressed over months to years. Nerve conduction studies (NCS), laboratory analysis, nerve MRI, and nerve ultrasound were performed. RESULTS: NCS revealed demyelinating neuropathy in all with multifocal conduction blocks or increased terminal latency indices...

INTRODUCTION: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a common treatable neuropathy, however nearly 20% of patients remain refractory to standard therapy for unclear reasons. METHODS: We did a retrospective review of 37 patients referred for CIDP refractory to intravenous immunoglobulin (IVIg), plasmapheresis, and/or corticosteroids. Clinical findings, electrophysiological studies, and response to further therapeutic interventions were assessed...
