In February 2016, the World Health Organization declared Zika virus (ZIKV) infection a public health emergency of international concern, given the precipitous spread of the virus across the Americas. Unlike arboviruses such as Chikungunya and Dengue, which have also recently emerged in the western hemisphere, ZIKV was identified in communities where concurrent neurologic conditions such as microcephaly and Guillain-Barre (GB) syndrome were occurring at alarming rates. Thus, investigations to systematically evaluate the link between ZIKV, congenital malformations (including microcephaly) and GB syndrome remain a top priority...

Fisher syndrome (FS), a variant of Guillain-Barré syndrome (GBS), is characterized by the clinical triad of ophthalmoplegia, ataxia, and areflexia. The lesion sites for these unique clinical features include the oculomotor nerves and group 1a neurons in the dorsal root ganglion, and the presence of FS is determined by the expression of ganglioside GQ1b in the human nervous system. Neurophysiological findings suggest that ataxia and areflexia are due to an impaired proprioceptive afferent system. Typically, the soleus H-reflex is absent and a body-sway analysis using posturography shows a 1-Hz peak, which indicates proprioception dysfunction...

Recent studies have clearly underscored the association between Zika virus (ZIKV) and severe neurological diseases such as microcephaly and Guillain-Barre syndrome. Given the historical complacency surrounding this virus, however, no significant antiviral screenings have been performed to specifically target ZIKV. As a result, there is an urgent need for a validated screening method and strategy that is focused on highlighting potential anti-ZIKV inhibitors that can be further advanced via rigorous validation and optimization...

The efficacy of plasma exchange (PE) and intravenous immunoglobulin (IVIg) therapies for Guillain-Barré syndrome have been established by numerous randomized controlled trials. However, 10-20 % of GBS patients cannot walk without aid after one year from onset of the disease. Thus, new treatment is required for these intractable cases. The Japan GBS outcome study (J-GOS) has been conducted to identify clinical or biological markers that predict the prognosis of Japanese GBS patients at an early stage. In the future, we expect to provide intractable patients so predicted with novel therapy, including molecular target drugs...

Fisher syndrome is regarded as a peculiar inflammatory neuropathy associated with ophthalmoplegia, ataxia, and areflexia. The disorder is associated with preceding infection, cerebrospinal fluid albumino-cytological dissociation, and spontaneous recovery, and regarded as a variant of Guillain-Barré syndrome. The discovery of anti-GQ1b IgG antibodies led to dramatic advances in understanding the pathophysiology of Fisher syndrome. The lesions in Fisher syndrome are determined by expression of ganglioside GQ1b in the human nervous system...

Zika virus has attracted increasing attention because of its potential for causing human neural disorders, including microcephaly in infants and Guillain-Barré syndrome. Its NS3 helicase domain plays critical roles in NTP-dependent RNA unwinding and translocation during viral replication. Our structural analysis revealed a pre-activation state of NS3 helicase in complex with GTPγS, in which the triphosphate adopts a compact conformation in the absence of any divalent metal ions. In contrast, in the presence of a divalent cation, GTPγS adopts an extended conformation, and the Walker A motif undergoes substantial conformational changes...

Ours was a descriptive observational cross-sectional study carried out in a tertiary care hospital in eastern India over a period of one year to study the profile of neurological involvement in paediatric dengue patients. Of 71 laboratory-confirmed cases, 20 (28.17%) had neurological involvement. Common forms observed were acute encephalopathy (40%), encephalitis (30%), pure motor weakness (15%), transverse myelitis (5%), acute disseminated encephalomyelitis (5%) and Guillain-Barré syndrome (5%). The dengue IgM antibody could be detected in the cerebrospinal fluid of only two patients with encephalitis...

Hepatitis E virus (HEV) infections are not limited to the liver but may also affect other organs. Several diseases, including Guillain-Barré syndrome, neuralgic amyotrophy, glomerulonephritis, cryoglobulinemia, pancreatitis, lymphoma, thrombopenia, meningitis, thyreoiditis and myocarditis have been observed in the context of hepatitis E. To date the definite pathophysiological links between HEV and extrahepatic manifestations are not yet established. However, it is suggested that HEV-infection might be causative based on serological studies, case series, in vitro data and animal models...

BACKGROUND: Zika virus (ZIKV; Flaviviridae, Flavivirus) was declared a public health emergency of international concern by the World Health Organization (WHO) in February 2016, because of the evidence linking infection with ZIKV to neurological complications, such as Guillain-Barre Syndrome in adults and congenital birth defects including microcephaly in the developing fetus. Because development of a ZIKV vaccine is a top research priority and because the genetic and antigenic variability of many RNA viruses limits the effectiveness of vaccines, assessing whether immunity elicited against one ZIKV strain is sufficient to confer broad protection against all ZIKV strains is critical...

Background The recent epidemics of Zika virus (ZIKV) implicated it as the cause of serious and potentially lethal congenital conditions such microcephaly and other central nervous system defects, as well as the development of the Guillain-Barré syndrome in otherwise healthy patients. Recent findings showed that anti-Dengue antibodies are capable of amplifying ZIKV infection by a mechanism similar to antibody-dependent enhancement, increasing the severity of the disease. This scenario becomes potentially catastrophic when the global burden of Dengue and the advent of the newly approved anti-Dengue vaccines in the near future are taken into account...

We report a full-term neonate presenting with symptomatic congenital cytomegalovirus (CMV) infection with hepatosplenomegaly, 'blueberry muffin' rash, intracranial calcifications, thrombocytopenia and respiratory distress. Maternal history was relevant for Guillain-Barré syndrome (GBS) during the first trimester of pregnancy. CMV infection is an important cause of GBS; thus, women presenting GBS during pregnancy should be screened for CMV infection. If positive, they may benefit from specialised monitoring and treatment in the antenatal period, which may decrease the risk of major neurodevelopmental sequelae of congenital CMV in the neonate...

After prompt diagnosis, severe myasthenia gravis and Guillain-Barré syndrome (GBS) usually require management in the intensive care unit. In the myasthenic patient, recognition of precipitating factors is paramount, and frequent monitoring of bulbar, upper airway, and/or respiratory muscle strength is needed to identify impending myasthenic crisis. Noninvasive ventilation can be attempted prior to intubation and mechanical ventilation in the setting of respiratory failure. Cholinesterase inhibitors should be discontinued, but resumed prior to extubation, and steroid dosage could be increased once the airway is secured...

The rapidly expanding Zika virus (ZIKV) epidemic has affected thousands of individuals with severe cases causing Guillain-Barré syndrome, congenital malformations, and microcephaly. Currently, there is no available vaccine or therapy to prevent or treat ZIKV infection. We evaluated whether sofosbuvir, an FDA-approved nucleotide polymerase inhibitor for the distantly related hepatitis C virus, could have antiviral activity against ZIKV infection. Cell culture studies established that sofosbuvir efficiently inhibits replication and infection of several ZIKV strains in multiple human tumor cell lines and isolated human fetal-derived neuronal stem cells...

Sporadic Zika virus infections had only occurred in Africa and Asia until an outbreak in Micronesia (Oceania) in 2007. In 2013 to 2014, several outer Pacific Islands reported local outbreaks. Soon thereafter, the virus was likely introduced in Brazil from competing athletes from French Polynesia and other countries that participated in a competition there. Transmission is thought to have occurred through mosquito bites and spread to the immunologically naive population. Being also a flavivirus, the Zika virus is transmitted by the Aedes mosquito that is endemic in South and Central America that is also the vector of West Nile virus, dengue, and chikungunya...

The epidemics of Chikungunya virus (CHIKV) and Zika virus (ZIKV) infections have been considered the most important epidemiological occurrences in the Americas. The clinical picture of CHIKV infection is characterized by high fever, exanthema, myalgia, headaches, and arthralgia. Besides the typical clinical picture of CHIKV, atypical manifestations of neurological complications have been reported: meningo-encephalitis, meningoencephalo-myeloradiculitis, myeloradiculitis, myelitis, myeloneuropathy, Guillain-Barré syndrome and others...

A widespread epidemic of Zika virus (ZIKV) infection was reported in 2015 in South and Central America, with neurological symptons including meningoencephalitis and Guillain-Barré syndrome in adults, besides an apparent increased incidence of microcephaly in infants born to infected mothers. It is becoming a necessity to have a trustworthy animal model to better understand ZIKV infection. In this study we used newborn white Swiss mice as a model to investigate the ZIKV strain recently isolated in Brazil. ZIKV was inoculated via intracerebral and subcutaneous routes and analysed through gross histopathology and immunohistochemistry...

This article describes a young, otherwise healthy woman who presented to the ED with numbness in her feet and was discharged. Twenty-four hours later, she returned because of difficulty walking; in 48 hours she could not walk without assistance. Although Guillain-Barré syndrome was suspected initially, the patient's weakness, sensory loss, and autonomic dysfunction eventually were diagnosed as transverse myelitis, a myelopathy often associated with infectious or autoimmune diseases. The article describes the presentation, diagnostic evaluation and criteria, treatment, and prognosis of transverse myelitis...

The mitochondrial pyruvate dehydrogenase enzyme complex (PDHC) plays an important role in aerobic energy metabolism and acid-base equilibrium. PDHC contains of 5 enzymes, 3 catalytic (E1, E2, E3) and 2 regulatory, as well as 3 cofactors and an additional protein (E3-binding protein) encoded by nuclear genes. The clinical presentation of PDHC deficiency ranges from fatal neonatal lactic acidosis to chronic neurologic dysfunction without lactic acidosis. Paroxysmal neurologic problems such as intermittent ataxia, episodic weakness, exercise-induced dystonia and recurrent demyelination may also be seen although they are rare...
