Guillain-Barré syndrome (GBS) is an acute, immune-mediated polyradiculoneuropathy characterized by rapidly progressive paresis and sensory disturbances. Moderate to severe and often intractable neuropathic pain is a common symptom of GBS, but its underlying mechanisms are unknown. Pathology of GBS is classically attributed to demyelination of large, myelinated peripheral fibers. However, there is increasing evidence that neuropathic pain in GBS is associated with impaired function of small, unmyelinated, nociceptive fibers...

BACKGROUND: Zika disease has transformed into a serious global health problem due to the rapid spread of the arbovirus and alarming severity including congenital complications, microcephaly and Guillain-Barré syndrome. Zika virus (ZIKV) is primarily transmitted to humans through the bite of an infective mosquito, with Aedes aegypti being the main vector. METHODS: We successfully developed a ZIKV experimental transmission model by single infectious Ae. aegypti bite to a laboratory mouse using circulating Brazilian strains of both arbovirus and vector...

The Guillain-Barré syndrome (GBS) has been reported as a possible complication of acute chikungunya infection. The chikungunya epidemics, which occurred in Martinique and Guadeloupe in 2014, affected 308,000 people in these two islands. GBS occurred during or immediately after acute chikungunya infection in 13 patients (10 men, three women; mean age: 61 years). Median time from acute chikungunya to GBS onset was 9 days. Twelve patients were treated with intravenous polyvalent immunoglobulins, nine of whom improved within 7 days...

BACKGROUND: In Finland a vaccination programme against human papillomavirus (HPV) was introduced in November 2013 for girls aged 11-12 years with a catchup for girls 13-15 years. Allegations that HPV vaccine is causing Guillain Barré syndrome (GBS) and non-specific diagnostic entities, such as chronic fatigue syndrome/systemic exertion intolerance disease (CFS/SEID) and postural orthostatic tachycardia syndrome (POTS), continue to surface. We examined population register-based incidence rates of CFS/SEID, GBS and POTS to provide baseline data for future HPV vaccine safety evaluations...

BACKGROUND: It has been approximately 70 years since the discovery of the Zika virus (ZIKV). It had been established that the virus causes mild infections, and is confined to Africa and Asia; however, major changes in the clinical and epidemiologic patterns of ZIKV infection have occurred in recent years. The virus has attracted intense interest because of the possible association of several autoimmune and neurodevelopmental disorders. METHODS: We present a summary of the articles that attempt to explain the ZIKV unknowns, and strengthen the association with some disorders that are thought to be related to ZIKV, by describing the discovery milestones from the initial identification of the virus to the present day...

Zika virus (ZIKV) is a mosquito-borne flavivirus that emerged recently as a global health threat, causing a pandemic in the Americas. ZIKV infection mostly causes mild disease, but is linked to devastating congenital birth defects and Guillain-Barré syndrome in adults. The high level of cross-reactivity among flaviviruses and their cocirculation has complicated serological approaches to differentially detect ZIKV and dengue virus (DENV) infections, accentuating the urgent need for a specific and sensitive serological test...

Multiple sclerosis, Guillain-Barré syndrome, peripheral nerve polyneuropathy and others comprise a group of demyelinating diseases characterized by progressive (and eventually irreversible) loss of oligodendrocytes and myelin sheaths in the white matter of the brain. To date, the etiology of these disorders is not well known and no effective treatments are currently available. Therefore, further research is needed to gain a better understand and treat these patients. To accomplish this goal, it is necessary to have appropriate animal models that closely resemble the pathophysiology of these diseases...

Guillain Barré syndrome (GBS) is a post-infectious acute autoimmune polyradiculopathy. Cerebrospinal fluid (CSF) total protein level and plasma neutrophil/lymphocyte ratio (NLR) are related with autoimmune response. We aimed to reach a prognostic indicator for GBS by using electrophysiological findings, protein level of CSF, and plasma NLR based on Medical Research Council (MRC) sum score data. Cases who met diagnostic criteria of GBS and followed at least six months were enrolled in the study. Nerve conduction study (NCS) and lumbar puncture were performed one week after symptom onset...

Guillain-Barre Syndrome (GBS) is a life-threatening condition in which patients may present to the Emergency Department in respiratory distress leading to death. The early identification and treatment of such a condition is paramount in preventing mortality. While there are many infections associated with GBS, the association with Lyme disease is uncommon. Through our case we aim to highlight Borrelia burgdorferi as an important antecedent infection associated with the development of GBS. In this case we report a 31-year-old male who was diagnosed with Lyme disease and GBS with relevant clinical presentation including progressive numbness and weakness in bilateral hands and feet for the past 1week along with areflexia...

We describe a 52-year-old woman presenting with acute onset of severe burning paraesthesia in the hands and feet associated with allodynia and antalgic gait. At the time of admission to hospital no motor weakness was present. A diagnosis of Guillain-Barré syndrome (GBS) was considered when neurophysiological studies were completed showing convincing evidence of demyelination on motor conduction studies and sural sparing on sensory nerve studies.(1) We describe this case as a sensory variant of GBS. Clinical improvement followed treatment with a single course of intravenous immunoglobulin (IVIG)...

The recent Zika viral (ZIKV) epidemic has been associated with severe neurological pathologies such as neonatal microcephaly and Guillain-Barre syndrome but unfortunately no vaccine or medication is effectively available yet. Zika NS2B-NS3pro is essential for the proteolysis of the viral polyprotein and thereby viral replication. Thus NS2B-NS3pro represents an attractive target for anti-Zika drug discovery/design. Here, we have characterized the solution conformations and catalytic parameters of both linked and unlinked Zika NS2B-NS3pro complexes and found that the unlinked complex manifested well-dispersed NMR spectra...

BACKGROUND: Zika virus (ZIKV), a previously neglected mosquito-borne virus, is prompting worldwide concern because of its connection with congenital defects, Guillain-Barré syndrome, meningoencephalitis and myelitis in infected individuals. However, no specific antiviral therapy is available at present. In this study, we investigated the in vitro susceptibility of geographically and temporally distinct zika viruses against the RNA polymerase inhibitors, favipiravir (T-705) and ribavirin (RIBV)...
