Zika virus was recognised in 2016 as an important vector-borne cause of congenital malformations and Guillain-Barré syndrome, during a major epidemic in Latin America, centred in Northeastern Brazil. The WHO and Pan American Health Organisation (PAHO), with partner agencies, initiated a coordinated global response including public health intervention and urgent scientific research, as well as ethical analysis as a vital element of policy design. In this paper, we summarise the major ethical issues raised during the Zika epidemic, highlighting the PAHO ethics guidance and the role of ethics in emergency responses, before turning to ethical issues that are yet to be resolved...

Background: The long-term follow-up system for Guillain-Barré syndrome (GBS) is not well established worldwide. In our study, the preliminary data of the long-term prognosis of GBS are collected to explore the prognosis of GBS and the effect of intravenous immunoglobulin (IVIg) treatment. Methods: The follow-up data of 186 patients with GBS admitted from 2003 to 2013 were collected in 2015 via phone interview. The GBS disability scale score was ranked by clinician to evaluate the long-term prognosis...

Zika virus (ZIKV) infection causes devastating congenital abnormities and Guillain-Barré syndrome. The ZIKV envelope (E) protein is responsible for viral entry and represents a major determinant for viral pathogenesis. Like other flaviviruses, the ZIKV E protein is glycosylated at amino acid N154. To study the function of E glycosylation, we generated a recombinant N154Q ZIKV that lacks the E glycosylation and analyzed the mutant virus in mammalian and mosquito hosts. In mouse models, the mutant was attenuated, as evidenced by lower viremia, decreased weight loss, and no mortality; however, knockout of E glycosylation did not significantly affect neurovirulence...

BACKGROUND: Guillain-Barre syndrome (GBS) is a rare immune-related neurological disorder with high mortality and morbidity, but the comorbid psychiatric disorders garnered little attention in the GBS patients. This study aimed to investigate the association between GBS and the risk of developing psychiatric disorders. METHODS: A total of 18,192 enrolled patients, with 4548 study subjects who had suffered GBS, and 13,644 controls matched for gender and age, from the Inpatient Dataset of 2000-2013 in Taiwan, and selected from the National Health Insurance Research Database (NHIRD)...

BACKGROUND: In Bangladesh, most patients with Guillain-Barré syndrome (GBS) cannot afford standard treatment with intravenous immunoglobulin (IVIG) or a standard plasma exchange (PE) course, which partly explains the high rate of mortality and residual disability associated with GBS in this country. Small volume plasma exchange (SVPE) is an affordable and potentially effective alternative form of plasma exchange. SVPE is the repeated removal of small volumes of supernatant plasma over several days via sedimentation of patient whole blood...

Intravenous immunoglobulin (IVIG) and therapeutic plasma exchange (TPE) are well-known therapeutic modalities in Guillain-Barré syndrome (GBS). In developing countries like India, where plasma-derived products (IVIG) are not easily available, and affordable TPE is preferred. Here, we reported a case of severe GBS, who was treated with daily plasma exchange (PLEX) rather than recommended alternate day schedule. A 16-year-old male adolescent of severe GBS, i.e., on mechanical ventilator was treated with the plasmapheresis regimen consisted of removal of 1...

Invasive meningococcal disease, although rare, can present as sudden, life-threatening disease with high risk of mortality or severe long-term sequelae. The main prevention strategy for invasive meningococcal disease in the United States is the routine vaccination of adolescents and other persons at increased risk of meningococcal disease with quadrivalent meningococcal conjugate vaccines. Two such vaccines are currently licensed and available in the United States, Menactra® (Sanofi Pasteur) and Menveo® (Glaxo Smith Kline), and usage in the adolescent population have steadily increased since their introduction...

Viral infections have long been the cause of severe diseases to humans, increasing morbidity and mortality rates worldwide, either in rich or poor countries. Yellow fever virus, H1N1 virus, HIV, dengue virus, hepatitis B and C are well known threats to human health, being responsible for many million deaths annually, associated to a huge economic and social cost. In this context, a recently introduced flavivirus in South America, called Zika virus (ZIKV), led the WHO to declare in February 1st 2016 a warning on Public Health Emergency of International Concern (PHEIC)...

Zika virus (ZIKV), a mosquito-transmitted flavivirus, responsible for sporadic outbreaks of mild and febrile illness in Africa and Asia, re-emerged in the last decade causing serious human diseases including microcephaly, congenital malformations, and Guillain-Barré syndrome. Although genomic and phylogenetic analyses suggest that genetic evolution may have led to enhanced virulence of ZIKV, experimental evidence supporting the role of specific genetic changes in virulence is currently outstanding. One sequence motif, VNDT, containing an N-linked glycosylation site in the envelope (E) protein, is polymorphic, being absent in many of the African isolates while present in all isolates from the recent outbreaks...

Although first isolated almost 70 years ago, Zika virus (ZIKV; Flavivirus, Flaviviridae) has only recently been associated with significant outbreaks of disease in humans. Several severe ZIKV disease manifestations have also been recently documented, including fetal malformations, such as microcephaly, and Guillain-Barré syndrome in adults. Although principally transmitted by mosquitoes, sexual transmission of ZIKV has been documented. Recent publications of several interferon receptor knockout mouse models have demonstrated ZIKV-induced disease...

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...

Infectious diseases remain a leading source of human morbidity and mortality. Recently, emerging infectious diseases are dominated by zoonoses, and eventually rising considerably. Their emergence is dependent on various factors especially, socioeconomic, environmental and ecological factors etc. Recently, the swift spread of Zika virus (ZIKV) through the Americas, simultaneously with the association of infection with microcephaly and Guillain-Barré syndrome, has strained this previously overlooked virus into the global attention...

Although Guillain-Barré syndrome (GBS) has higher incidence and poor outcome in Bangladesh, mortality from GBS in Bangladesh has never been explored before. We sought to explore the frequency, timing, and risk factors for deaths from GBS in Bangladesh. We conducted a prospective study on 407 GBS patients who were admitted to Dhaka Medical College Hospital, Dhaka, Bangladesh from 2010 to 2013. We compared deceased and alive patients to identify risk factors. Cox regression model was used to adjust for confounders...

Arboviruses have been emerging in different parts of the world due to genetic changes in the virus, alteration of the host and vector population dynamics, or because of anthropogenic environmental factors. These viruses' capacity for adaptation is notable, as well as the likelihood of their emergence and establishment in new geographic areas. In Brazilian epidemiologic scenario, the most common arboviruses are DENV, CHIKV, and ZIKV, although others may spread in the country. Little is yet known of the impact of viral co-circulation, which would theoretically result in more intense viremia or other immunological alterations that could trigger autoimmune diseases, such as Guillain-Barré syndrome...
