Objectives: Small-fiber polyneuropathy (SFPN) has various underlying causes, including associations with systemic autoimmune conditions. We have proposed a new cause; small-fiber-targeting autoimmune diseases akin to Guillain-Barré and chronic inflammatory demyelinating polyneuropathy (CIDP). There are no treatment studies yet for this 'apparently autoimmune SFPN' (aaSFPN), but intravenous immunoglobulin (IVIg), first-line for Guillain-Barré and CIDP, is prescribed off-label for aaSFPN despite very high cost...

PURPOSE OF REVIEW: Immune checkpoint inhibitors represent a major step forward in the field of oncologic immunotherapy these last years and have significantly increased survival of cancer patients in an ever-growing number of indications. These agents block specific immune checkpoint molecules (programmed cell death protein 1 and its ligand as well as cytotoxic T-lymphocyte-associated antigen 4) that normally downregulate the immune response. These new agents show a specific range of adverse effects induced by abnormal immunologic activation...

Xanthomatous sialadenitis (XS) is rarely reported. Here we report XS in a case of HLA-B27-positive ankylosing spondylitis showing also anti-MAG-positive polyneuropathy with IgM-kappa dysimmunoglobulinemia/paraproteinemia, lung small cell carcinoma and buccal squamous cell carcinoma (SCC). The lesions were identified in submandibular and labial minor salivary glands of a neck dissection specimen (made during a buccal 1.7 cm large SCC resection procedure). The oral SCC was resected at 8 months after the diagnosis of the lung small cell carcinoma (with skull dome metastases, revealed by a superior cava syndrome) and at 2 months after radiotherapy...

Guillain-Barré syndrome (GBS) and transverse myelitis (TM) both represent immunologically mediated polyneuropathies of major clinical importance. Both are thought to have a genetic predisposition, but as of yet no specific genetic risk loci have been clearly defined. Both are considered autoimmune, but again the etiologies remain enigmatic. Both may be induced via molecular mimicry, particularly from infectious agents and vaccines, but clearly host factor and co-founding host responses will modulate disease susceptibility and natural history...

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a debilitating condition caused by autoimmune demyelination of peripheral nerves. CIDP is associated with increased IL-10, a cytokine with well-described anti-inflammatory effects. However, the role of IL-10 in CIDP is unclear. In this study, we demonstrate that IL-10 paradoxically exacerbates autoimmunity against peripheral nerves. In IL-10-deficient mice, protection from neuropathy was associated with an accrual of highly activated CD4+ T cells in draining lymph nodes and absence of infiltrating immune cells in peripheral nerves...

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a common, treatable, autoimmune peripheral neuropathy considered to produce imbalance by weakness and proprioceptive impairment rather than vestibular impairment. We measured semicircular canal vestibular function in 21 CIDP patients (15M/6F) by the video head impulse test and postural stability with a battery comprising the modified Clinical Test of Sensory Integration and Balance, the Berg Balance Scale, the Dynamic Gait Index, the Fall Efficiency Scale, and the International Cooperative Ataxia Rating Scale...

Immune checkpoint inhibitors, used as immunotherapy in the treatment of melanoma and refractory cancer, may trigger autoimmune disorders. We describe a case of Guillain-Barré syndrome (GBS) after the treatment with ipilimumab and nivolumab and review 4 other reported cases. We confirmed the diagnosis of GBS by electrodiagnostic and cerebrospinal fluid studies. Electrodiagnostic results showed findings consistent with acquired demyelinating polyneuropathy and cerebrospinal fluid showed albuminocytologic dissociation...

BACKGROUND: Cerebrospinal fluid (CSF) analysis in patients with particular neurologic disorders is a powerful tool to evaluate specific central nervous system inflammatory markers for diagnostic needs, because CSF represents the specific immune micro-environment to the central nervous system. METHODS: CSF samples from 49 patients with multiple sclerosis (MS), chronic inflammatory demyelinating polyneuropathy (CIDP), and non-inflammatory neurologic disorders (NIND) as controls were submitted to protein expression profiles of 47 inflammatory biomarkers by multiplex Luminex bead assay to investigate possible differences in the inflammatory process for MS and CIDP...

Guillain-Barre syndrome (GBS) is an autoimmune disease of the nervous system and is the most common acute polyneuropathy. Both cellular and humoral immunity are believed to be involved in the pathogenesis of GBS, and various types of activated CD4+ T cells are thought to orchestrate the onset and progression of GBS. Lymphoplasma exchange (LPE) filtering out activated lymphocytes while exchanging plasma has been used for GBS treatment for years. However the treatment is still not yet optimal. In order to assess the efficacy of this treatment, we evaluate the effect of LPE and determine the appropriate frequency of LPE treatments for GBS patients through comparing the neurological deficit scores and the changes in related immunology indicators of GBS patients before and after LPE treatment...

Zika virus (ZIKV) infection has been associated with the development of Guillain-Barré syndrome (GBS) and idiopathic thrombocytopenic purpura (ITP). Whether ZIKV infection is related to other autoimmune diseases is unknown. Therefore, an association study to evaluate rheumatic and thyroid autoimmunity in patients with ZIKV disease was conducted through a panel of 14 autoantibodies. In addition, a literature review on ZIKV, and GBS and ITP was performed. Our results disclosed a lack of association of rheumatoid and thyroid autoimmunity with ZIKV disease...

This chapter reviews the diseases of the peripheral nerves from a neuropathologic point of view, with a special focus on specific morphologic changes, and includes a summary of the histopathologic methods available for their diagnosis. As the rate of obesity and the prevalence of type 2 diabetes increase, diabetic neuropathy is the most common cause of peripheral neuropathy. Many systemic disorders with metabolic origin, like amyloidosis, hepatic failure, vitamin deficiencies, uremia, lipid metabolism disorders, and others, can also cause axonal or myelin alterations in the peripheral nervous system...

PURPOSE OF REVIEW: This article describes the methods of diagnosis and management of the sensory-predominant polyneuropathies. To simplify the approach to this category of patients, sensory-predominant polyneuropathies are divided broadly into either small fiber (or pain-predominant) neuropathies and large fiber (or ataxia-predominant) neuropathies, of which the sensory neuronopathies (dorsal root ganglionopathies) are highlighted. RECENT FINDINGS: Physicians can now easily perform skin biopsies in their offices, allowing access to the gold standard pathologic diagnostic tool for small fiber neuropathies...

INTRODUCTION: Autoantibodies to the alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor and N-methyl-d-aspartate (NMDA) receptor are known to be the causes of autoimmune encephalitis particularly limbic encephalitis. The involvement of the peripheral nervous system is rarely reported. METHODS: We analyzed the serial nerve conduction studies of a previously reported case of anti-AMPA receptor encephalitis, who was presented with conscious disturbance and quadriplegia...

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired autoimmune demyelinating polyneuropathy characterized by symmetrical diffuse weakness that also can rarely affect bulbar and respiratory muscles. The study objective was to describe perioperative outcomes of patients with CIDP who received general anesthesia. This retrospective observational study evaluated patients with active (diagnosed or treated within the previous year) CIDP who underwent general anesthesia at our institution between January 1, 2010, and December 31, 2015...

The rat sciatic nerve has attracted widespread attention as an excellent model system for studying autophagy alterations in peripheral neuropathies. In our laboratory, we have developed an original rat model, which we used currently in routine novel drug screening and to evaluate treatment strategies for chronic inflammatory demyelinating polyneuropathy (CIDP) and other closely related diseases. Lewis rats injected with the S-palmitoylated P0(180-199) peptide develop a chronic, sometimes relapsing-remitting type of disease...

Satoru Oji, Kyoichi Nomura
In recent years, immunoadsorption has been increasingly recognized as an alternative to therapeutic plasma exchange and used for the treatment of neurological disorders such as Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, myasthenia gravis, neuromyelitis optica spectrum disorders, and multiple sclerosis, as well as autoimmune encephalitis. Unlike therapeutic plasma exchange, which requires fluid replacement with a blood solution such as fresh frozen plasma or albumin, immunoadsorption is a blood purification technique that enables the selective removal of humoral factors from separated plasma through a high-affinity adsorbent with tryptophan or phenylalanine...

OBJECTIVES: Compared to type 1 diabetes, the role of the immune and autoimmune pathogenetic mechanisms is much less studied in the type 2 diabetes. Toll-like receptors 4 (TLR4) have a leading role in inflammation, insulin resistance, and vascular damage. This study aimed to analyze the relationship between the polymorphisms in TLR4 gene and different stages in the glucose continuum from prediabetes to the type 2 diabetes and chronic microvascular complications. MATERIALS AND METHODS: The study included 113 patients with the type 2 diabetes, 29 participants with prediabetes, and 28 controls...
