AIDP

BACKGROUND AND PURPOSE: Clinical symptoms and laboratory indices for acute inflammatory demyelinating polyneuropathy (AIDP), a variant of Guillain-Barré syndrome, and acute-onset chronic inflammatory demyelinating polyneuropathy (A-CIDP) were analyzed to identify factors that could contribute to early differential diagnosis. METHODS: A retrospective chart review was performed on 44 AIDP and 44 A-CIDP patients looking for any demographic characteristics, clinical manifestations or laboratory parameters that might differentiate AIDP from acutely presenting CIDP...

INTRODUCTION: Guillain-Barré syndrome (GBS) is a rare disease that affects almost 0.8-1.9 cases per 100,000 people worldwide every year. This is the most prevalent cause of subacute flaccid paralyzing illness today. It is a subacute inflammatory demyelinating polyradiculoneuropathy; the typical scenario involves ascending symmetrical flaccid paralysis, but in some circumstances, sensory, autonomic, and cranial neuropathy may also be involved. Several vaccines have been found to have complications since the previous century...

Guillain-Barre syndrome (GBS) is described by a wide range of motor impairment, flaccidity, hyporeflexia, and progressive and ascending flaccid paralysis. Group B Streptococcus , also known as Streptococcus agalactia and Campylobacter jejuni , are Gram-positive bacteria also known as the leading cause of GBS; its variants are acute motor axonal neuropathy (AMAN), acute motor and sensory axonal neuropathy (AMSAN), acute inflammatory demyelinating neuropathy (AIDP), and Miller-Fisher syndrome (MFS)...

<p style="text-align: justify;"><strong>Introduction</strong> - Guillain-Barr&eacute; syndrome (GBS) is an acute inflammatory demyelinating polyneuropathy. In the vast majority of patients, 1-4 weeks before the onset of GBS-related symptoms, an event such as upper respiratory tract or gastrointestinal tract infection, surgical intervention or vaccination is present. To the best of our knowledge, this is the first case of GBS that occurred after intravesical Bacillus Calmette-Gu&eacute;rin (BCG) therapy in the absence of tuberculosis or any other infection in the English literature...

BACKGROUND: Bladder cancer (BLCA) is a prevalent malignancy worldwide. Anoikis remains a new form of cell death. It is necessary to explore Anoikis-related genes in the prognosis of BLCA. METHODS: We obtained RNA expression profiles from the The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus databases for dimensionality reduction analysis and isolated epithelial cells, T cells and fibroblasts for copy number variation analysis, pseudotime analysis and transcription factor analysis based on R package...

OBJECTIVE:  The risk factors for respiratory insufficiency in children with Guillain-Barré syndrome (GBS) are poorly known. This study aimed to investigate the factors associated with respiratory insufficiency in children with GBS. METHODS:  This retrospective study included children diagnosed with GBS by pediatric neurologists and admitted at the Wuhan Children's Hospital and other hospitals from January 2013 to October 2022. The patients were divided into the respiratory insufficiency and nonrespiratory insufficiency groups according to whether they received assist breathing during treatment...

Charcot-Marie-Tooth's disease (CMT) represents the most common inherited neuropathy. Most patients are diagnosed during late stages of disease course during adulthood. We performed a review of clinical, neurophysiological, and genetic diagnoses of 32 patients with genetically defined childhood-onset demyelinating CMT under clinical follow-up in a Brazilian Center for Neuromuscular Diseases from January 2015 to December 2019. The current mean age was 33.1 ± 18.3 years (ranging from 7 to 71 years) and mean age at defined genetic diagnosis was 36...

BACKGROUND AND AIMS: In the pathophysiology of Guillain-Barre syndrome (GBS), inflammation and immunity are believed to play a key role. The neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), and platelet-lymphocyte ratio (PLR) have been recently identified as potential markers of inflammation or immunity. This study aimed to investigate whether NLR, MLR, and PLR are associated with GBS characteristics in children. We also assessed the impact of the COVID-19 pandemic on the characteristics of GBS in Iran...

INTRODUCTION: We aimed to evaluate and compare the clinical and electrophysiological features of post-COVID-19 Guillain-Barré syndrome (GBS) and non-COVID-19 GBS patients over the last five years. METHODS: We retrospectively analyzed patients diagnosed with GBS between October 2016 and September 2021. They were divided into five groups according to the flu season and the COVID-19 pandemic. Groups 1-4 were identified as non-COVID-19 groups, whereas Group 5 constituted the post-COVID-19 group...

BACKGROUND: Biomarkers for diagnosis of inflammatory neuropathies, assessment of prognosis, and treatment response are lacking. METHODS: CSF and EDTA plasma from patients with Guillain-Barré syndrome (GBS), chronic inflammatory demyelinating polyneuropathy (CIDP), healthy controls (HC) and disease controls were analyzed with Olink multiplex proximity extension assay (PEA) from two independent cohorts. Levels of interleukin-8 (IL8) were further analyzed with ELISA in patients with GBS, CIDP, paraproteinemia-related demyelinating polyneuropathy (PDN), multifocal motor neuropathy (MMN), HC and disease controls...

INTRODUCTION: Hyperactivity immune responses to coronavirus disease 2019 (COVID-19) can lead to several manifestations in the human organ. One of the most affected organs is the respiratory system. Not only does it affect the respiratory system, but hyperactivity can also affect the neuromuscular and cerebrovascular systems, though it is scarce for both systems to be affected simultaneously. CASE PRESENTATION: We presented a mild COVID-19 patient with a history of progressive general weakness and dysphagia on day seventh day after patient was first diagnosed with COVID-19, which continued with diplopia and shortness of breath...

This study aimed to describe the spectrum of the results of neuromuscular electrodiagnostic investigations performed by age and pathology in paediatric patients. This retrospective observational study took place from January 2019 to December 2021. Electrodiagnostic records of paediatric patients (birth to 15 years) were referred to the electromyography (EMG) laboratory for EMG and nerve conduction study (NCS). Electrodiagnostic and demographic data were collected. Among these, 151 (56%) were males and 118 (44%) were females...

We report a case of a six-year-old male with Charcot-Marie-Tooth disease (CMT) type 1B due to  MPZ gene mutation who experienced an acute worsening of his symptoms a few years after the diagnosis. He was not able to walk without assistance and had transitory paresthesia in his hands, 10 days after suffering from an upper respiratory and diarrheal illness. The investigation revealed elevated cerebrospinal fluid (CSF) protein levels with no pleocytosis, and sensory and motor chronic demyelinating neuropathy without active denervation findings on electrophysiological studies...

BACKGROUND: Syphilis is associated with a wide variety of systemic presentations, earning it the moniker "The great mimicker". Neurosyphilis is classically associated with meningovasculitis in the acute-subacute stage and tabes dorsalis and dementia paralytica in later stages. However, one of the less well described presentations include Guillain-Barre Syndrome. This case presents a patient with an ascending polyneuropathy suspicious for Guillain-Barre Syndrome who also had other atypical findings including a truncal sensory loss, optic disc swelling, and rash ultimately found to have neurosyphilis...

BACKGROUND: Guillain-Barré syndrome (GBS) is the leading cause of non-polio acute flaccid paralysis worldwide, emphasizing the importance of epidemiological studies on this condition. Therefore, well-designed epidemiological studies in different populations can provide a better understanding of the characteristics of patients with GBS and the nature of the disease. To our knowledge, no previous study has attempted to describe the characteristics of patients with GBS in Kingdom of Saudi Arabia (KSA) based on disease subtypes and clinical features in both adult and pediatric patients...

OBJECTIVES: Anti-neurofascin-155 IgG4 (NF-155) antibody disease has previously been associated with a subset of patients with chronic inflammatory demyelinating polyradiculoneuropathy. We report a case of NF-155 positive polyneuropathy that initially presented as an acute inflammatory demyelinating polyradiculoneuropathy. The patient responded appropriately to treatment but subsequently progressed over a 3-month period, resulting in quadriplegia, areflexia, and oculobulbar paralysis. METHODS: Case report and literature review...

Guillain-Barré syndrome (GBS) is an immune-mediated disease of the peripheral nervous system that can occur in both children and adults. The classic presentation of GBS is characterized by progressive symmetrical, ascending muscle weakness. Patients with GBS require meticulous monitoring due to the risk of bulbar syndrome, respiratory failure and autonomic dysfunction, which can be life-threatening. Early diagnosis and timely prescription of pathogenetic therapy for GBS are particularly important, especially in young children...

In acute inflammatory demyelinating polyneuropathy (AIDP), myelin vesiculation mediated by complement activation contributes to nerve injury. Macrophage infiltration of the spinal roots has been demonstrated in AIDP, but its pathological significance remains uncertain. The present study aimed to investigate the role of macrophages in the pathogenic sequence of AIDP. A rabbit model of AIDP was induced by immunization with galactocerebroside. Immunostaining was performed to localize the macrophages and myelin injury...
