[Miller-Fisher/Guillain-Barré overlap syndrome following COVID-19 vaccination].

Background: Anti-GQ1B syndrome includes a group of diseases characterized by antibody-mediated polyneuropathy. Guillain Barre syndrome (GBS) and the Miller-Fisher syndrome (MFS) have been related to COVID-19 vaccine application.

Clinic Case: 48-year-old man, with history of Pfizer-BioNTech vaccination against COVID-19, 5 days prior to the symptoms, who assisted to the Emergency room with blurred vision and diplopia; adding dysarthria, facial diplegia and left upper limb weakness after 48 hours.

Guillain-Barre syndrome following Pfizer-BioNTech (BNT162b2) vaccination: a case report.

Introduction: Pfizer-BioNTech (BNT162b2) is one of the mRNA vaccines currently approved by the WHO and the Food and Drug Administration (FDA) against COVID-19.

Case Presentation: Here, the authors report a case of an 8-year-old female with Guillain-Barré syndrome following the second dose of Pfizer-BioNTech (BNT162b2) vaccination requiring respiratory support who was managed with intravenous immunoglobulin.

Discussion: There have been reports of Guillain-Barré syndrome following the Pfizer-BioNTech vaccination.

Lactobacillus rhamnosus ameliorates experimental autoimmune neuritis via modulation of gut microbiota and metabolites.

Background: Guillain-Barre syndrome (GBS), an autoimmune disease of the peripheral nervous system, is hallmarked by demyelination and immune cellular infiltration. Experimental autoimmune neuritis (EAN), considered a GBS prototype model, has been studied for its potential therapeutic benefits from lactobacilli. This study evaluated the protective role of Lactobacillus GG (GG) for treatment in EAN.

Causal role of the pyrimidine deoxyribonucleoside degradation superpathway mediation in Guillain-Barré Syndrome via the HVEM on CD4 + and CD8 + T cells.

Immune system regulation is a key indicator of the gut microbiota (GM) influencing disease development. The causal role of the GM in Guillain-Barré syndrome (GBS) and whether it can be mediated by immune cells is unknown. Genome-wide association study (GWAS) summary statistics for the GM were obtained from the Dutch Microbiota Project (n = 7,738) and the FINRISK 2002 (FR02) cohort (n = 5,959).

Complicated neurological pathways: tuberculoma with Guillain-Barre syndrome - an uncharted clinical odyssey.

Tuberculosis is a global disease and presents with an array of neurological manifestations. Presentation varies from meningitis, radiculo-myelitis, tuberculoma, brain abscess and other combinations. The association of Guillain-Barre' syndrome (GBS) with tuberculosis has been reported in a few reports.

Miller fisher syndrome with positive anti-GQ1b/GT1a antibodies associated with COVID-19 infection: A case report.

Background: Miller fisher syndrome (MFS) is a variant of Guillain-Barré syndrome, an acute immune-mediated peripheral neuropathy that is often secondary to viral infections. Anti-ganglioside antibodies play crucial roles in the development of MFS. The positive rate of ganglioside antibodies is exceptionally high in MFS patients, particularly for anti-GQ1b antibodies.

H, N and C backbone resonance assignment of the N-terminal region of Zika virus NS4B protein in detergent micelles.

Zika virus has raised global concerns due to its link to microcephaly and Guillain-Barré syndrome in adults. One of viral nonstructural proteins-NS4B, an integral membrane protein, plays crucial roles in viral replication by interacting with both viral and host proteins, rendering it an attractive drug target for antiviral development. We purified the N-terminal region of ZIKV NS4B (NS4B NTD) and reconstituted it into detergent micelles.

Clinical characteristics and functional outcomes of pediatric Guillain-Barré syndrome admitted to the Neuro-intensive care unit: a decade-long retrospective observational study.

Background: Guillain-Barré Syndrome (GBS) remains a significant contributor to acute flaccid paralysis in pediatric patients worldwide. Despite its impact, studies focusing on pediatric GBS requiring intensive care unit (ICU) management are limited. This study aimed to address this gap by exploring the clinical and outcome characteristics of pediatric GBS necessitating ICU care.

Diagnostic criteria and therapeutic implications of rapid-onset demyelinating polyneuropathies.

Guillain-Barré syndrome (GBS) and acute-onset chronic inflammatory demyelinating polyneuropathy (A-CIDP) are the most common autoimmune polyneuropathies. Their aetiology is unclear. The pathomechanism includes damage mainly to the myelin sheath and, in the long-term process, secondary axonal loss.

Postpartum Guillain-Barré Syndrome Presenting as Acute Motor Axonal Neuropathy in a Young Female: A Report of a Rare Case.

This case report presents a rare instance of acute motor axonal neuropathy (AMAN), a subtype of Guillain-Barré syndrome (GBS), in a 25-year-old postpartum female. The patient experienced a seven-day history of progressive, ascending motor weakness in all four limbs, beginning shortly before delivery and rapidly worsening postpartum. Notably, she exhibited no sensory deficits, a hallmark feature of AMAN, which was confirmed by nerve conduction studies revealing significant motor axonal involvement with preserved sensory function.

Optimal control applied to Zika virus epidemics in Colombia and Puerto Rico.

Zika virus (ZIKV) is a mostly non-lethal disease in humans transmitted by mosquitoes or humans that can produce severe brain defects such as microcephaly in babies and Guillain-Barré syndrome in elderly adults. The use of optimal control strategies involving information campaigns about insect repellents and condoms alongside an available safe and effective vaccine can prevent the number of infected humans with ZIKV. A system of nonlinear ordinary differential equations is formulated for the transmission dynamics of ZIKV in the presence of three control strategies to evaluate the impact of various scenarios during a ZIKV epidemic.

COVID-19-Associated Neurological Complications in Children.

Objectives: Neurological manifestations of Severe Acute Respiratory Syndrome coronavirus-2 have been well documented in adults during and after infection with the virus as well as after vaccination. The incidence of severe neurological symptoms among children is very low. This study aimed to analyze the varied neurological manifestations after COVID-19 infection among children and give a report on a single-center experience with these severe neurological symptoms.

Tremor Following Guillain Barré Syndrome.

Background: Neuropathic tremor occurs with damage to the peripheral nervous system. Guillain-Barré syndrome (GBS) causes acute paralysis following nerve inflammation sometimes resulting in long-term disability. It is unclear how frequent and severe tremor is following GBS.

Relationship between Guillain-Barré syndrome and Cardiovascular disease: A bidirectional Mendelian randomization study.

Background And Objective: Guillain-Barré syndrome (GBS) and cardiovascular diseases (CVDs) have been observed to have a potential association, with GBS potentially leading to cardiovascular complications. However, these observational studies may be influenced by confounding factors. This study aimed to assess the causal relationship between GBS and CVDs, including heart failure (HF), atrial fibrillation (AF), and coronary artery disease (CAD), using a two-sample bidirectional Mendelian randomization (MR) analysis.
