RATIONALE: Numerous cases of post-infectious Guillain-Barré syndrome (GBS) have been reported in the literature. Toscana virus (TOSV) is an arthropod-borne emerging pathogen in the Mediterranean area. PATIENT CONCERNS: A 40-year-old male patient was admitted to hospital for acute facial weakness, associated to numbness paraesthesias at lower and upper limbs. The neurological examination revealed facial diplegia and reduced tendon reflexes. The nerve conduction studies documented an acute motor and sensory axonal neuropathy (AMSAN); the lumbar puncture detected albuminocytologic dissociation...

BACKGROUND: Therapeutic plasma exchange (TPE) is an extracorporeal blood purification technique that is designed to remove substances with a large molecular weight. The TPE procedure includes removal of antibodies, alloantibodies, immune complexes, monoclonal protein, toxins or cytokines, and involves the replenishment of a specific plasma factor. The aim of the study was to describe the clinical response to TPE in various neurological patients, and to assess the clinical response to this therapy...

Flaviviruses are RNA viruses that constitute a worrisome threat to global human and animal health. Zika virus (ZIKV), which was initially reported to cause a mild disease, recently spread in the Americas, infecting millions of people. During this recent epidemic, ZIKV infection has been linked to serious neurological diseases and birth defects, specifically Guillain-Barrè syndrome (GBS) and microcephaly. Because information about ZIKV immunity remains scarce, we assessed the humoral response of immunocompetent mice to infection with three viral strains of diverse geographical origin (Africa, Asia and America)...

Immusorba TR (IM-TR) and PH (IM-PH) were developed as immunoadsorbents from nonbiological materials as affinity ligands for removal of pathogenic substances. The immunoadsorbents in IM-TR and IM-PH are immobilized on a polyvinyl alcohol gel with tryptophan and phenylalanine, respectively, as a ligand. IM-TR is mainly clinically applied to autoimmune neurological diseases such as myasthenia gravis, Guillain-Barré syndrome, and multiple sclerosis. IM-PH is also applied to neurological diseases but mainly to rheumatic diseases such as rheumatoid arthritis and systemic lupus erythematosus...

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...

Free-living amoebae (FLA) are protozoa that are widely distributed in the environment mainly in water and soil related habitats. These amoebae have also been reported to be associated with some bacterial pathogens for humans such as Campylobacter spp. The species C. jejuni is the causative agent of about 90% of human campylobacteriosis cases worldwide and this disease may even end up in severe autoimmune sequelae as Guillain-Barré syndrome (GBS). In this study, the interactions between the strain Acanthamoeba castellanii Neff and Campylobacter jejuni was investigated...

Inflammation in Guillain-Barré syndrome (GBS) is manifested by changes in matrix metalloproteinase (MMP) and pro-inflammatory cytokine expression. We investigated the expression of MMP-2, -9 and TNF-α and correlated it with pathological changes in sciatic nerve tissue from Campylobacter jejuni-induced chicken model for GBS. Campylobacter jejuni and placebo were fed to chickens and assessed for disease symptoms. Sciatic nerves were examined by histopathology and immunohistochemistry. Expressions of MMPs and TNF-α, were determined by real-time PCR, and activities of MMPs by zymography...

BACKGROUND: While there are guidelines for the use of intravenous immunoglobulins in children with Guillain-Barre syndrome and myasthenia gravis based on high-level evidence studies, data is fewer for the majority of neurologic disorders in this age group. Neuronal antibodies are detected in children with seizures of autoimmune etiology. Intravenous immunoglobulins with their broad immunomodulatory mechanism of action could be ideally effective in different forms of immune-dysregulated intractable epilepsies such as autoimmune epilepsy and autoimmune Rasmussen encephalitis...

Neurological complications are frequently recognized with weight reduction surgeries for morbid obesity. The spectrum of peripheral neuropathies complicating the weight loss surgery is wide, and among them, the acute axonal peripheral neuropathy resembling Guillain-Barre syndrome is rare and only less than a dozen cases are reported. We present three cases, which after bariatric surgery developed acute polyneuropathy that rapidly progressed over 4 weeks from the onset. All patients responded to aggressive parenteral Vitamin B1 and B12 replacement therapy...

Age influences incidence and prognosis of Guillain Barre Syndrome (GBS), common cause of ascending areflexic quadriparesis. Dedicated studies on elderly GBS are infrequent. This study aimed to describe clinical features and outcome at hospital-discharge in patients aged≥60years with GBS. Medical records of 70 elderly GBS over 15years were analysed. Mean symptom-duration was 5.78±4.5days and onset-to-peak 5.14±4.4days. Antecedent events preceded GBS by 8.07±9.9days and included: fever (n=19), respiratory infection (n=6), and gastroenteritis (n=5)...

Approximately one-half of advanced cutaneous melanomas have a V600 mutation in the BRAF gene that activates the mitogen-activated protein kinase pathway. The combination of BRAF plus MEK inhibitors is one of the most effective treatments for these patients. Severe neurological toxicities have been reported in the literature. However, these toxicities are very rare. Here, we present one patient with acute motor and sensory axonal neuropathy, which is a subtype of Guillain-Barre syndrome, secondary to treatment with MEK inhibitors...

Zika virus (ZIKV; family Flaviviridae; genus Flavivirus) is a pathogenic mosquito-borne RNA virus that currently threatens human health in the Americas, large parts of Asia and occasionally elsewhere in the world. ZIKV infection is often asymptomatic but can cause severe symptoms including congenital microcephaly and Guillain-Barré syndrome. The positive single-stranded RNA genome of the mosquito-borne ZIKV requires effective replication in two evolutionary distinct hosts - mosquitoes and primates. In addition to some of the viral proteins, the ZIKV genomic RNA and functional RNAs produced thereof aid in the establishment of productive infection and the evasion of host cell antiviral responses...

Guillain-Barré syndrome (GBS) is a term that is used to describe a group of immune-mediated peripheral neuropathies, with the most common feature being rapid polyradiculoneuropathy. The exact etiology of this syndrome is unknown. In the field of orthopedics, GBS has been reported to occur after total hip arthroplasty, orthopedic trauma, and spine surgery. We report a unique case of GBS after elective revision lumbar spine surgery. A 62-year-old female presented with persistent low back pain and radiculopathy and elected to have revision lumbar spine surgery...
