Disease Overview: POEMS syndrome is a paraneoplastic syndrome due to an underlying plasma cell neoplasm. The major criteria for the syndrome are polyradiculoneuropathy, clonal plasma cell disorder (PCD), sclerotic bone lesions, elevated vascular endothelial growth factor, and the presence of Castleman disease. Minor features include organomegaly, endocrinopathy, characteristic skin changes, papilledema, extravascular volume overload, and thrombocytosis. Read More

Demyelinating diseases represent a spectrum of disorders that impose significant burden on global economy and society. Generally, the prognosis of these diseases is poor and there is no available cure. In recent decades, research has shed some light on the biology and physiology of Schwann cells and its neuroprotective effects in the peripheral nervous system (PNS). Read More

BACKGROUND Beriberi due to thiamine (vitamin B1) deficiency has two clinical presentations. Patients with dry beriberi present with neuropathy, and patients with wet beriberi present with heart failure, with or without neuropathy. Dry beriberi can mimic the most common form of Guillain-Barre syndrome (GBS), an acute inflammatory demyelinating polyradiculoneuropathy (AIDP). Read More

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

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.

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

Rationale: Autonomic symptoms are not uncommon in chronic inflammatory demyelinating polyneuropathy (CIDP), but they are mostly mild and transient and are overshadowed by somatic manifestations. Here, we report a very unusual case of CIDP with severe autonomic symptom, intestinal obstruction, as initial and persistent symptom which responded well to high-dose glucocorticoid and intravenous immunoglobulin treatment.

Patient Concerns: We described a patient with CIDP with precedent and long-lasting incomplete intestinal obstruction. Read More

Here, we describe 2 unique cases of FSGS, 1 with GBS and the other with CIPD. We believe that reviewing these multisystemic diseases will help in better understanding of FSGS pathogenesis. 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.

Combined central and peripheral demyelination (CCPD) is a rare chronic inflammatory disorder of the nervous system. In this article, we report on a CCPD patient with a very unusual pattern of central demyelination, comprising recurrent cerebral tumefactive demyelinating lesions (three times, each one in a new area of the brain) and one episode of longitudinally extensive transverse myelitis. This patient could not be classified as having multiple sclerosis, or neuromyelitis optica spectrum disorder, or any other well-known inflammatory disorder of the central nervous system, associated with demyelinating neuropathy.

Objective: To describe an expanded teased nerve fibre classification in disease association.

Methods: We reviewed four newly proposed teased nerve fibre types (): Type J, rope-like fibres; K, fibril-like clumps of osmium positivity; L, cellular debris along and within nerve fibres; M, circular axonal inclusions surrounded by thin myelin. Different clinical pathological entities were studied for these fibre types including chronic inflammatory demyelinating polyradiculoneuropathy (CIDP: N=20); amyloid polyneuropathy (N=20); intraneural B-cell lymphoma (N=20) or adult-onset polyglucosan body disease (APBD: N=6) in comparison with 112 disease controls.

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

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.

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.

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a disorder characterized by motor symptoms such as weakness in both proximal and distal muscles with globally diminished or absent reflexes. Insulin neuritis is referred as an acute pain in the extremities, due to the damage of peripheral nerves affecting mainly small fibers, in diabetic patients treated with insulin who achieved rapid glycemic control. Pain is unusual in classic CIDP. Read More
