The current pandemic caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) is accompanied with a rapid increase of reports and papers detailing its neurological effects and symptoms. The virus infection causes respiratory illness named by the world health organization as corona virus 19 (COVID-19).This systematic review aims to study and summarize the different neurological manifestations of this virus. All articles published and indexed via Pubmed, Medline and Google Scholar databases between January 1st 2020 and February 28th 2021 that reported neurological symptoms of SARS-CoV-2 are reviewed following the Preferred Reporting Items for Systemic review and Meta-Analysis (PRISMA) guidelines...

OBJECTIVE: To compare clinical and nerve conduction studies (NCS) parameters predictive of outcome in children with acute inflammatory demyelinating polyneuropathy (AIDP) and acute motor axonal neuropathy (AMAN). METHODS: In this prospective observational study, NCS was done on all children at admission and repeated before discharge. Functional status of patients was graded as per Hughes Disability score. These children were followed up till they achieved independent walking...

Zika virus (ZIKV) infection during pregnancy has been linked to congenital abnormalities such as microcephaly in infants. An efficacious vaccine is still desirable for preventing the potential recurrence of ZIKV epidemic. Here, we report the generation of an attenuated ZIKV (rGZ02a) that has sharply decreased virulence in mice but grows to high titers in Vero cells, a widely approved cell line for manufacturing human vaccines. Compared to the wild-type ZIKV (GZ02) and a plasmid-launched rGZ02p, rGZ02a has 3 unique amino acid alterations in the envelope (E, S304F), non-structural protein 1 (NS1, R103K), and NS5 (W637R)...

INTRODUCTION: Guillain-Barré syndrome (GBS) is a common cause of flaccid paralysis. Up to a third of cases result in respiratory failure requiring mechanical ventilation. AIM: We aim to study the possible predictors of respiratory compromise requiring mechanical ventilation in cases of GBS as well as their clinical outcome in the UAE population. METHODOLOGY: A retrospective observational study was conducted between the periods of January 2009 till January 2019 in a tertiary center in Dubai...

Zika virus (ZIKV), a flavivirus transmitted primarily by infected mosquitos, can cause neurological symptoms such as Guillian-Barré syndrome and microcephaly. We developed several vaccinia virus (VACV) vaccine candidates for ZIKV based on replication-inducible VACVs (vINDs) expressing ZIKV pre-membrane (prM) and envelope (E) proteins (vIND-ZIKVs). These vIND-ZIKVs contain elements of the tetracycline operon and replicate only in the presence of tetracyclines. The pool of vaccine candidates was narrowed to one vIND-ZIKV containing a novel mutation in the signal peptide of prM that led to higher expression and secretion of E and production of virus-like particles, which was then tested for safety, immunogenicity, and efficacy in mice...

Coronavirus disease 2019 (COVID-19), due to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), emerged in Wuhan city, China in December 2019 and rapidly spread to other countries. The most common reported symptoms are fever, dry cough, myalgia and fatigue, headache, anorexia, and breathlessness. Anosmia and dysgeusia as well as gastrointestinal symptoms including nausea and diarrhea are other notable symptoms. This virus also can exhibit neurotropic properties and may also cause neurological diseases, including epileptic seizures, cerebrovascular accident, Guillian barre syndrome, acute transverse myelitis, and acute encephalitis...

Myelination and node of Ranvier formation play an important role in rapid conduction of nerve impulses, referred to as saltatory conduction, along axons in the peripheral nervous system. Here we report a human-human myelination model using human primary Schwann cells (SC) and human iPSC-derived motoneurons (iPSC-MNs) utilizing a serum-free medium supplemented with ascorbate to induce axonal myelination where 41.6% of SCs expressed the master transcription factor for myelination, early growth response protein 2 (Egr2)...

Zika virus (ZIKV) is a mosquito-borne flavivirus associated with Congenital Zika Syndrome (CZS), reflecting a wide range of congenital abnormalities in fetuses and infants infected with ZIKV before birth. ZIKV infections have also been associated with the neurological autoimmune disorder known as Guillian-Barré syndrome (GBS). To date, no vaccines or antiviral strategies are licensed for ZIKV. We used rational design to develop a novel ZIKV vaccine candidate using a Woodchuck Hepatitis core Antigen (WHcAg) Virus-Like Particle (VLP) scaffold for displaying selected antigens from the ZIKV Envelope (E) protein...

The Coronavirus disease due to SARS-CoV-2 emerged in Wuhan city, China in December 2019 and rapidly spread to more than 200 countries as a global health pandemic. There are more than 3.5 million confirmed cases and around 165,000 to 243,000 fatalities. The primary manifestation is respiratory and cardiac but neurological features are also being reported in the literature as case reports and case series. The most common reported symptoms to include headache and dizziness followed by encephalopathy and delirium...

RATIONALE: Guillian-Barré syndrome (GBS) is a devastating autoimmune disorder characterized by progressive ascending weakness, areflexia with or without autonomic and sensory disturbances. Hydrocephalus is a rare but well-documented complication in patients with GBS. However, due to the rarity of this condition, no treatment guideline for GBS with hydrocephalus is currently available. PATIENT CONCERNS: We describe a 23-year old woman with a history of bilateral limbs pain followed by dysarthria, dysphagia, severe quadriplegia 0/5, areflexia, loss of consciousness and dysautonomia...

Guillian-Barre Syndrome (GBS) typically presents as symmetrical ascending flaccid muscle weakness with areflexia, and with or without sensory symptoms. However, some patients may present atypically, and accordingly, different variants of GBS have been reported in the literature. Pharyngeal-cervical-brachial variant is one of the rare variants and is characterized by muscle weakness extending from the oropharyngeal and neck area to the proximal upper extremities. Many physicians and neurologists are unfamiliar about pharyngeal-cervical-brachial variant, which is often misdiagnosed as brainstem stroke, myasthenia gravis or botulism...

A 41-year-old woman presented with paresthesia and inability to walk for 7 days. She had history of fatigue, polyarthralgia and difficulty in swallowing food for the last 1 year. She became edentulous over the last 5 years and wore dentures for the same. She appeared pale, emaciated and had oral thrush. She had areflexic quadriparesis with weakness more in lower limbs compared with upper limbs. With the initial diagnosis of Guillian-Barre syndrome, she was given five cycles of plasmapheresis following which there was a significant improvement in power...

INTRODUCTION: Adenosine deaminase (ADA) deficiency causes severe immunodeficiency that is lethal in infancy. Enzyme replacement therapy (ERT) can improve the metabolic, immune and non-immune abnormalities in patients prior to transplantation, however, its benefits over extended periods are not well characterized. We describe a 28-year-old female who received ERT for 27 years. She suffered from EBV negative B cell lymphoma of the hip at 14 years of age and Guillian-Barre Syndrome 2 years later...

INTRODUCTION: Neuromuscular diseases (NMD) are characterised by progressive muscular impairment. The muscle weakness is directly related to respiratory muscles weakness, causing reduction in vital capacity, especially when associated with mechanical ventilation (MV). Conventional MV weaning in NMD is generally difficult. Weaning process can be conducted in protocols such as: 'T' piece or Pressure Support Ventilaton. Weaning failure is frequent because of muscle weakness. Protocol aim is to assess the effects of different weaning protocols in NMD patients receiving invasive MV in weaning success rate, duration of weaning, intensive care unit (ICU) stay, hospital stay and ICU mortality...

Chikungunya is an arboviral infection caused by Chikungunya virus, an RNA virus from Togaviridae family.1 The disease manifests as fever, rash and characteristically, with arthralgia.1 Chikungunya is strongly believed to have neurotropism but has not been well studied like other neurotropic arboviruses.2 Encephalitis appears to represent the most common clinical manifestation6 and occurs either simultaneously or within few days of onset of systemic symptoms, during the period of viremia. A delay of more than two weeks has been reported with other complications like myelitis, Guillian Barre syndrome and optic neuritis...

The Campylobacter and Arcobacter genera encompass closely related species that are ubiquitous in nature and are harboured in the gastrointestinal tract of many animals, including food-producing animals (cattle, sheep, pigs and poultry). In humans Campylobacter spp. is the cause of most of the gastroenteritis cases worldwide and in more severe cases the infection can result in Guillian Barré syndrome. Similarly, Arcobacter species can cause gastroenteritis as well as bacteraemia. Infections in humans can be induced by the consumption of contaminated vegetables, meat, milk and water...

Campylobacter jejuni is a major food-borne zoonotic pathogen, responsible for a large proportion of bacterial gastroenteritis cases, as well as Guillian-Barré and Miller-Fisher syndromes. During infection, tissue damage is mainly caused by bacteria invading epithelial cells and traversing the intestinal barrier. C. jejuni is able to enter the lamina propria and the bloodstream and may move into other organs, such as spleen, liver, or mesenteric lymph nodes. However, the involved molecular mechanisms are not fully understood...

Neurological manifestations are potentially associated with hepatitis E virus (HEV) infection in Europe, mainly attributed to genotype (GT) 3 HEV infection. In this study, we determined the frequency and causal relationship of HEV in patients with non-traumatic neurological disorders in China, where GT4 HEV is prevalent. 1117 consecutive patients diagnosed with neurological illnesses in a hospital of eastern China and 1475 healthy controls who took routine examination in the same hospital were tested for HEV by serology and molecular methods...
