Abstract
Coronavirus disease (COVID-19) has been associated with a diverse range of extrapulmonary manifestations since its global outbreak in 2019. One of its rare complications is Guillain-Barre Syndrome (GBS), a post-infectious neurological disorder that manifests with a characteristic ascending limb paralysis. Here, we describe the atypical case of a 42-year-old African American male who developed bilateral facial paralysis within five weeks of testing positive for COVID-19. Initial diagnostic imaging and blood studies were negative for acute pathology. Albuminocytological dissociation found in a subsequent analysis of the patient's cerebrospinal fluid and his appropriate therapeutic response to intravenous immunoglobulin (IVIg) indicated GBS as the most likely diagnosis.

Abstract
The COVID-19 pandemic continues to cause severe global disruption, resulting in significant excess mortality, overwhelming healthcare systems, and imposing substantial social and economic burdens on nations. While most of the attention and therapeutic efforts have concentrated on the acute phase of the disease, a notable proportion of survivors experience persistent symptoms post-infection clearance. This diverse set of symptoms, loosely categorized as long COVID, presents a potential additional public health crisis. It is estimated that 1 in 5 COVID-19 survivors exhibit clinical manifestations consistent with long COVID. Despite this prevalence, the mechanisms and pathophysiology of long COVID remain poorly understood. Alarmingly, evidence suggests that a significant proportion of cases within this clinical condition develop debilitating or disabling symptoms. Hence, urgent priority should be given to further studies on this condition to equip global public health systems for its management. This review provides an overview of available information on this emerging clinical condition, focusing on the affected individuals' epidemiology, pathophysiological mechanisms, and immunological and inflammatory profiles.

Abstract
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.We included data from 113 articles: eight prospective studies, 25 retrospective studies and the rest were case reports/series. COVID-19 can present with central nervous system manifestations, such as headache, encephalitis and encephalopathy, peripheral nervous system manifestations, such as anosmia, ageusia and Guillian Barre syndrome, and skeletal muscle manifestations, such as myalgia and myasthenia gravis. Our systematic review showed that COVID-19 can be manifested by a wide spectrum of neurological symptoms reported either in the early stage or within the course of the disease. However, a detailed comprehension of these manifestations is required and more studies are needed in order to improve our scientific knowledge and to develop preventive and therapeutic measures to control this pandemic.

Abstract
Aims Coronaviruses, SARS-CoV-2 particles are spherical and have proteins called spikes that stick out on the surface. COVID-19 most commonly affects the respiratory system, but various clinical manifestations on coronavirus have revealed their potential neurotropism. The neuroinvasive affinity of Coronavirus infections has been reported nearly for all the β Coronavirus infections, including MERS-CoV, SARS-CoV, HCoV-OC43 and HEV. Coronavirus invasion occurs through hypoxia injury, immune injury, ACE2, and direct infection. The pathophysiology of SARS-CoV-2 and other human Coronaviruses reveals the possible mechanisms of neurodegeneration. Methods A systematic literature review carried out from various search engines like Scopus, PubMed, Medline, and Elsevier for investigating the therapeutic perspective of association between Covid-19 and Guillain-Barré syndrome. Results SARS-CoV-2 uses angiotensin-converting enzyme 2 as its entry receptor and enters the central nervous system through a Blood-brain barrier constituted of inflammatory mediators, direct infection of the endothelial cells, or endothelial injury. Guillain-Barré syndrome is an autoimmune disease that injures and attacks the nerves in the peripheral nervous system. Studies suggest that the virus can infect peripheral neurons to cause direct damage through various mechanisms, including direct damage by cytokine-related injury, ACE2 receptors, and the sequelae of hypoxia. Conclusion we have discussed the possible mechanisms between neuroinvasion of SARs-cov2 and Guillain-barre syndrome.

Abstract
Background: To define the varied presentations of Guillain-Barré syndrome in children in the COVID era and 6 months' follow-up outcome. Methods: Ambispective study of 15 months' duration involving children with Guillain-Barré syndrome aged 1 month to 18 years at a tertiary care pediatric hospital. They were categorized into groups A and B based on COVID-19 serology testing. Hughes Disability Scale was used for disability assessment. Modified Rankin scale was used for improvement assessment in follow-up. Results: Of 19 children with Guillain-Barré syndrome, 9 (47%) were females and 10 (53%) were males. Groups A and B had children with negative (8) and positive serology (11), respectively. The most common presentation in both groups was motor weakness. Post-COVID pediatric Guillain-Barré syndrome presented with variants of Guillain-Barré syndrome rather than the classical form (P = .03). In group B, patients with elevated inflammatory markers had poor response to intravenous immunoglobulin, and 5 of 11 patients had good response to pulse steroids, probably depicting an inflammation-predominant pathology. Conclusion: Post-COVID Guillain-Barré syndrome in children presented with Guillain-Barré syndrome variants rather than the classic form. Neuroimaging is of great value in both confirming Guillain-Barré syndrome diagnosis and excluding differentials. Patients with elevated inflammatory markers and residual weakness may be given a pulse steroid trial.

Abstract
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has been an alarming situation worldwide for the past 2 years. The symptoms of coronavirus disease 2019 (COVID-19) are not only confined to the respiratory system but also affect a multitude of organ systems. Bradycardia associated with Guillain-Barré syndrome (GBS) is a rare autonomic and peripheral neurological complication of COVID-19. In this case report, we present the case of a 26-year-old man diagnosed with bradycardia associated with GBS after contracting COVID-19. Initially, this patient had the classical symptoms of COVID-19 and was hospitalized in the intensive care unit (ICU) for acute respiratory distress syndrome (ARDS). Then, he developed weakness in the lower extremities, diminished tendon reflexes, a loss of sensation without sphincter muscle disorders, and bradycardia. His bradycardia did not respond to atropine. The patient was treated concurrently with a high-flow nasal cannula, systemic corticosteroids, anticoagulation, and therapeutic plasma exchange (TPE) for COVID-19-induced ARDS, bradycardia, and GBS. His ARDS and bradycardia improved after the first cycle of TPE and medical treatment. After three cycles of TPE, the patient progressively recovered his muscle strength in the lower limbs and regained peripheral sensation. He was discharged from the hospital in stable condition after 4 weeks of hospitalization and was followed up after 6 months for cardiorespiratory and neurological complications. This case report elucidates the potential difficulties and challenges that physicians may encounter in diagnosing and treating COVID-19-induced bradycardia and GBS during the pandemic outbreak. However, the patient outcomes with the treatment combining the conventional treatment with therapeutic plasma exchange seem to be optimistic.

Abstract
Despite the advantages of getting access to the coronavirus disease 2019 (COVID-19) vaccines, their potential ability to induce severe adverse events (AEs) has been a significant concern. Neurological complications are significant among the various adverse events following immunization (AEFI) due to their likely durability and debilitating sequelae. Neurological AEs following COVID-19 vaccination can either exacerbate or induce new-onset neuro-immunologic diseases, such as myasthenia gravis (MG) and Guillain-Barre syndrome (GBS). The more severe spectrum of AEs post-COVID19 vaccines has included seizures, reactivation of the varicella-zoster virus, strokes, GBS, Bell's palsy, transverse myelitis (TM), and acute disseminated encephalomyelitis (ADEM). Here, we discuss each of these neurological adverse effects separately.

[PMCID: PMC9622433 DOI: 10.1016/j.heliyon.2022.e11328] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2022] [Revised: 06/03/2022] [Accepted: 10/25/2022] [Indexed: 11/06/2022] Open
Abstract
Introduction Although it has been proposed that SARS-CoV-2 can cause autoimmunity by inducing a transient immunodeficiency of both innate and acquired immunity components in which the immune system fails to identify autoantigens adequately, the exact mechanism that causes this disease remains unknown. We aim to systematically review of existing case reports for evidence of new autoimmune diseases in adults caused by SARS-CoV-2 infection. Methods PRISMA-P 2020 method was used to search for literature in "PubMed" databases using the string "COVID-19 AND autoimmune disease AND complication". We used JBI Critical Appraisal Checklist to assess the articles' quality. Results The literature search yielded 666 articles. 58 articles met our eligibility criteria. Based on our critical appraisal, we placed 35 articles in the good category and 23 articles in the medium category. Data was synthesized by grouping similar data into a table, including: gender, age, COVID-19 severity, types of autoimmune diseases, autoimmune profile and relevant findings, when autoimmune diseases are diagnosed, complications, and outcome to draw conclusions. The new onset of autoimmune disease in adult triggered by SARS-CoV-2 included Guillain-Barré syndrome and Miller Fisher syndrome, systemic lupus erythematosus, immune thrombocytopenia, autoimmune haemolytic anemia, latent autoimmune diabetes in adults, myositis, acute demyelinating encephalomyelitis, autoimmune encephalitis, central nervous system vasculitis, and autoimmune thyroid diseases. Conclusion SARS-CoV-2 can trigger new onset of a variety of autoimmune diseases. Doctors who take care patients infected by COVID-19 must be aware of the complications of autoimmune diseases. Future cohort or cross-sectional studies on SARS-CoV-2-related autoimmune disease should be conducted.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has affected the entire world, causing the coronavirus disease 2019 (COVID-19) pandemic since it was first discovered in Wuhan, China in December 2019. Among the clinical presentation of the disease, in addition to fever, fatigue, cough, dyspnea, diarrhea, nausea, vomiting, and abdominal pain, infected patients may also experience neurological and psychiatric repercussions during the course of the disease and as a post-COVID-19 sequelae. Thus, headache, dizziness, olfactory and gustatory dysfunction, cerebrovascular disorders, neuromuscular abnormalities, anxiety, depression, and post-traumatic stress disorder can occur both from the infection itself and from social distancing and quarantine. According to current evidence about this infection, the virus has the ability to infect the central nervous system (CNS) via angiotensin-converting enzyme 2 (ACE2) receptors on host cells. Several studies have shown the presence of ACE2 in nerve cells and nasal mucosa, as well as transmembrane serine protease 2, key points for interaction with the viral Spike glycoprotein and entry into the CNS, being olfactory tract and blood-brain barrier, through hematogenous dissemination, potential pathways. Thus, the presence of SARS-CoV-2 in the CNS supports the development of neuropsychiatric symptoms. The management of these manifestations seems more complex, given that the dense parenchyma and impermeability of brain tissue, despite protecting the brain from the infectious process, may hinder virus elimination. Still, some alternatives used in non-COVID-19 situations may lead to worse prognosis of acute respiratory syndrome, requiring caution. Therefore, the aim of this review is to bring more current points related to this infection in the CNS, as well as the repercussions of the isolation involved by the pandemic and to present perspectives on interventions in this scenario.

This study aims to assess clinical–neurophysiological features of an adult, Italian GBS cohort over 11 years. Methods Retrospective (from 1 January 2011 to 31 December 2021) analysis was carried out on patients admitted to the Siena University Hospital who fulfilled the GBS diagnostic criteria. Demographic data, clinical characteristics, treatment, need of mechanical ventilation (MV), laboratory and electrophysiological tests, preceding infections/vaccination/other conditions, and comorbidities were collected for each patient. Results A total of 84 patients (51 men, median age of 61 years), were identified. GBS subtype was classified as acute inflammatory demyelinating polyneuropathy (AIDP) in the 66.6% of patients, acute motor/sensory axonal neuropathy (AMAN/AMSAN) in 20.2%, and the Miller Fisher syndrome in 5 (5.9%). Flu syndrome and gastrointestinal infection were the most common preceding conditions. In total, five (5.9%) subjects had concomitant cytomegalovirus (CMV) infection. Cranial nerve involvement occurred in 34.5% of subjects. Differences between the axonal and AIDP forms of GBS concerned the presence of anti-ganglioside antibodies. In total, seven (8.33%) patients required MV. Discussion The epidemiological and clinical characteristics of GBS in different countries are constantly evolving, especially in relation to environmental changes. This study provides updated clinical-epidemiological information in an Italian cohort.

Abstract
In this article we review complications to the peripheral nervous system that occur as a consequence of viral infections, with a special focus on complications of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). We discuss neuromuscular complications in three broad categories; the direct consequences of viral infection, autoimmune neuromuscular disorders provoked by viral infections, and chronic neurodegenerative conditions which have been associated with viral infections. We also include discussion of neuromuscular disorders that are treated by immunomodulatory therapies, and how this affects patient susceptibility in the current context of the coronavirus disease 2019 (COVID-19) pandemic. COVID-19 is associated with direct consequences to the peripheral nervous system via presumed direct viral injury (dysgeusia/anosmia, myalgias/rhabdomyolysis, and potentially mononeuritis multiplex) and autoimmunity (Guillain Barré syndrome and variants). It has important implications for people receiving immunomodulatory therapies who may be at greater risk of severe outcomes from COVID-19. Thus far, chronic post-COVID syndromes (a.k.a: long COVID) also include possible involvement of the neuromuscular system. Whether we may observe neuromuscular degenerative conditions in the longer term will be an important question to monitor in future studies.

Abstract
BACKGROUNDS SARS-CoV-2 infection typically presents with fever and respiratory symptoms. Besides this, COVID-19 related central and peripheral nervous system manifestations are emerging. OBJECTIVES This study summarises the demographics, clinical profile, laboratory findings, management strategies, and outcomes in a large number of patients with COVID-19 related GBS and its variants. We also compared its clinical profile with Zika and dengue virus-related GBS. METHODS Authors carried out a literature search up to Dec 31, 2020, in MEDLINE, PubMed, SCOPUS, Cochrane database, and Google Scholar for all published articles. RESULTS The study identified 54 different types of articles consisting of 70 cases from 17 countries worldwide. Maximum cases 15 (21.4%) were identified from Italy, followed by USA 12 (17.1%), Spain 11 (15.7%), and Iran 10 (14.3%). The age group more than 60 years had most cases with 32 (45.7%) cases followed by age group 40-60 with cases 25 (35.7%) with male and female ratio 2. Maximum cases were treated with IVIG infusion 58 (82.9%), followed by Plasma exchange 13 (18.6%) cases. Out of 70 cases, 7 (10%) cases were manifested as Miller-Fisher syndrome. The most predominant electrodiagnostic variant was demyelinating neuropathy in 41 (73.21%) cases. The outcome reported in 67 cases was survival in 63 (90%) cases and the death of 4 (5.7%) cases. CONCLUSION Covid 19 related GBS were reported worldwide with a better outcome. Both postinfectious or parainfectious patterns were reported. Early recognition with prompt management of GBS can prevent further severe morbidity and mortality.

Abstract
The worldwide pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected an estimated 200 million people with over 4 million deaths. Although COVID-19, the disease caused by the SARS-CoV-2 virus, is primarily a respiratory disease, an increasing number of neurologic symptoms have been reported. Some of these symptoms, such as loss of smell or taste, are mild and non-life threatening, while others, such as stroke or seizure, are more critical. Many of these symptoms remain long after the acute illness has passed, a phenomenon known as "long COVID" or postacute sequelae of SARS-CoV-2 infection (PASC). Neurological symptoms can be difficult to study due to the complexity of the central and peripheral nervous system. These neurologic symptoms can be difficult to identify and quantitate. This narrative review will describe approaches for assessing neurologic manifestations of COVID-19, with examples of the data they provide, as well as some directions for future research to aid in understanding the pathophysiology of COVID-19-related neurological implications.

Abstract
Increasing literature has linked COVID‐19 to peripheral nervous system (PNS) diseases. In addition, as we move from the pandemic to the vaccination era, literature interest is shifting towards the potential association between COVID‐19 vaccines and PNS manifestations. We reviewed published literature on COVID‐19, COVID‐19 vaccines and PNS manifestations between 1 January 2020 and 1 December 2021. For Guillain‐Barré syndrome (GBS), isolated cranial neuropathy (ICN) and myositis associated with COVID‐19, the demographic, clinical, laboratory, electrophysiological and imaging features were included in a narrative synthesis. We identified 169 studies on COVID‐19‐associated complications, including 63 papers (92 patients) on GBS, 29 papers (37 patients) on ICN and 11 papers (18 patients) on myositis. Additional clinical phenotypes included chronic inflammatory demyelinating polyneuropathy, vasculitic neuropathies, neuralgic amyotrophy, critical care‐related complications, and myasthenia gravis. PNS complications secondary to COVID‐19 vaccines have been reported during randomized clinical trials, in real‐world case reports, and during large‐scale surveillance programs. These mainly include cases of GBS, Bell's palsy, and cases of neuralgic amyotrophy. Based on our extensive review of the literature, any conclusion about a pathophysiological correlation between COVID‐19 and PNS disorders remains premature, and solely supported by their temporal association, while epidemiological and pathological data are insufficient. The occurrence of PNS complications after COVID‐19 vaccines seems limited to a possible higher risk of facial nerve palsy and GBS, to a degree that widespread access to the ongoing vaccination campaign should not be discouraged, while awaiting for more definitive data from large‐scale surveillance studies.

Abstract
Background Beyond the typical respiratory symptoms associated with novel coronavirus, increasing evidence has been reported of the neurological manifestations affecting both the central and peripheral nervous systems.
Case presentation We observed a 30-year-old Persian woman developing acute motor sensory axonal neuropathy, a variant of Guillain–Barré syndrome that overlaps Miller Fisher syndrome, 30 days after confirmed coronavirus disease-2019 infection. Our case highlight the rare occurrence of Guillain–Barré syndrome overlapping with Miller Fisher during the coronavirus disease-2019 pandemic. These neurologic manifestations may occur because of an aberrant immune response to coronavirus disease-2019. Conclusions The early recognition of Guillain–Barré syndrome symptoms is critical, given the associated severe motor disabilities that may seriously limit the quality of life of these patients. We may still have much to learn about the co-occurrence of Guillain–Barré syndrome and Miller Fisher to improve the quality of life of these patients requiring an accurate evaluation by neurologists.

Abstract
BACKGROUND In January 2020, the first case of Guillain Barre syndrome (GBS) due to COVID-19 was documented in China. GBS is known to be postinfectious following several types of infections. Although causality can only be proven through large epidemiological studies, we intended to study this association by a thorough review of the literature. METHODS We searched PubMed, EMBASE, and Google scholar and included all papers with English or Spanish full text and original data of patients with GBS and recent COVID infection. Variables of interest were demographics, diagnostic investigations, and the latency between arboviral and neurological symptoms. Further variables were pooled to identify GBS clinical and electrophysiological variants, used treatments, and outcomes. The certainty of GBS diagnosis was verified using Brighton criteria. RESULTS We identified a total of 109 GBS cases. Ninety-nine cases had confirmed COVID-19 infection with an average age of 56.07 years. The average latency period between the arboviral symptoms and neurologic manifestations for confirmed COVID-19 cases was 12.2 d. The predominant GBS clinical and electromyography variants were the classical sensorimotor GBS and acute demyelinating polyneuropathy respectively. Forty cases required intensive care, 33 cases required mechanical ventilation, and 6 cases were complicated by death. CONCLUSIONS Studies on COVID-19-related GBS commonly reported sensorimotor demyelinating GBS with frequent facial palsy. The time between the onset of infectious and neurological symptoms suggests a postinfectious mechanism. Early diagnosis of GBS in COVID-19 patients is important as it might be associated with a severe disease course requiring intensive care and mechanical ventilation.

Abstract
There have been several reported cases of severe acute respiratory syndrome (SARS-CoV-2) infection that were associated with an increased incidence of neurological manifestations, including Guillain–Barré syndrome (GBS). This review aims to present information on the reports of GBS associated with coronavirus disease 2019 (COVID-19) infection. Our review is retrospective work examining articles published from the 1 April 2020 to the 8 May 2021 in the English language. We used the diagnostic criteria and classification published by the National Institute of Neurological Disorders and Stroke and Brighton Collaboration. GBS is usually a postinfectious syndrome, but GBS in the COVID-19 pandemic also takes on a para-infectious profile. In the reports, the genetic factor has a role in developing GBS in some patients. In conclusion, the association between COVID-19 and GBS is not very clear. Still, one mechanism is strongly associated with COVID-19 and immune-mediated neurological complications, which is molecular mimicry between SARS-CoV-2 and human autoantigens.

Abstract
'Post-COVID-19 syndrome' refers to symptoms in the convalescent phase following initial COVID-19 infection. This term encompasses a wide array of presentation involving lungs, heart and the neuromuscular system. Pulmonary manifestations include post-COVID-19 fibrosis, which is akin to post acute respiratory distress syndrome fibrosis and may reflect the permanent damage to the lungs following an initial bout of infection. Cardiovascular system is often involved, and the presentation can be in terms of acute coronary syndrome, myocarditis and heart failure. Clinical manifestations are often varied and non-specific, which entails a detailed workup and a multidisciplinary approach. Post-COVID-19 syndrome adds to the overall disease morbidity and leads to a prolonged hospital stay, greater healthcare utilisation and loss of productivity marring the country's dwindling economy. Thus, it is imperative that post-COVID-19 syndrome be prevented and identified early followed by a prompt treatment.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been linked to the Guillain-Barré syndrome (GBS). The objective of the present study is to identify specific clinical features of cases of GBS reported in the literature associated with SARS-CoV-2 infection. We searched Pubmed, and included single case reports and case series with full text in English, reporting original data of patients with GBS and a confirmed recent SARS-CoV-2 infection. Clinical data were extracted. We identified 28 articles (22 single case reports and 6 case series), reporting on a total of 44 GBS patients with confirmed SARS-CoV-2 infection. SARS-CoV-2 infection was confirmed through serum reverse transcriptase-polymerase chain reaction in 72.7% of cases. A total of 40 patients (91%) had symptoms compatible with SARS-CoV-2 infection before the onset of the GBS. The median period between the onset of symptoms of SARS-CoV-2 infection and symptoms of the GBS was 11.2 days (range, 2-23). The most common clinical features were: leg weakness (61.4%), leg paresthesia (50%), arm weakness (50.4%), arm paresthesia (50.4%), hyporeflexia/areflexia (48%) and ataxia (22.7%). In total, 38.6% (n = 17) were found to have facial paralysis. Among 37 patients in whom nerve-conduction studies and electromyography were performed, of which 26 patients (59.1%) were consistent with the acute inflammatory demyelinating polyneuropathy subtype of the GBS. The present retrospective analysis support the role of the SARS-CoV-2 infection in the development of the GBS, may trigger GBS as para-infectious disease, and lead to SARS-CoV-2-associated GBS.

Abstract
The global pandemic caused by SARS-CoV-2, or COVID-19, continues to impact all facets of daily life. Clinical manifestations of COVID-19 commonly include musculoskeletal symptoms such as myalgias, arthralgias, and neuropathies/myopathies. The inflammatory response and its impact on the respiratory system have been the focus of most studies. However, the literature is more limited regarding the inflammatory response and its implications for other organ systems, specifically the musculoskeletal system. Previous studies have described how systemic inflammation may play a role in bone and joint pathology. Furthermore, it is important to understand the effects current therapeutics used in the treatment of COVID-19 may have on the musculoskeletal system. In this study, we will review the current understanding of the effect COVID-19 has on the musculoskeletal system, provide an overview of musculoskeletal symptoms of patients infected with the virus, and address key issues for clinicians to address during the care of COVID-19 patients.

Abstract
Introduction Coronavirus disease 2019 (COVID-19) is associated to neuromuscular symptoms in up to 10.7% of hospitalized patients. Nevertheless, the extent of muscular involvement in infected subjects with no signs of myopathy has never been assessed with neurophysiological investigations. Methods Over a 3-week period — from April 30 through May 20, 2020 — a total of 70 patients were hospitalized in the Internal Medicine Ward of the Fondazione IRCCS Ca’ Granda Ospedale Maggiore Policlinico in Milan, Italy. After excluding patients who underwent invasive ventilation and steroid treatment, 12 patients were evaluated. Nerve conduction studies (NCS) included the analysis of conduction velocity, amplitude, and latency for bilateral motor tibial, ulnar nerves, and sensory sural and radial nerves. Unilateral concentric-needle electromyography (EMG) was performed evaluating at least 4 areas of 8 selected muscles. For each muscle, spontaneous activity at rest, morphology, and recruitment of motor unit action potentials (MUAPs) were evaluated. Results While nerve conduction studies were unremarkable, needle electromyography showed myopathic changes in 6 out of 12 subjects. All patients were asymptomatic for muscular involvement. Clinical features and laboratory findings did not show relevant differences between patients with and without myopathic changes. Conclusion Our data show that in SARS-CoV-2 infection muscular involvement can occur despite the absence of clinical signs or symptoms and should be considered part of the disease spectrum. The application of muscle biopsy to unravel the mechanisms of myofiber damage on tissue specimens could help to clarify the pathogenesis and the treatment response of coronavirus-mediated injury.

[PMID: 34239495 PMCID: PMC8258108 DOI: 10.3389/fneur.2021.678136] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Accepted: 05/14/2021] [Indexed: 12/31/2022] Open
Abstract
Guillain–Barré syndrome (GBS) is a potentially fatal, immune-mediated disease of the peripheral nervous system that is usually triggered by infection. Only a small number of cases of GBS associated with COVID-19 infection have been published. We report here five patients with GBS admitted to the Neurology, Psychiatry, and Neurosurgery Hospital, Assiut University/Egypt from July 1 to November 20, 2020. Three of the five patients were positive for SARS-CoV-2 following polymerase chain reaction (PCR) of nasopharyngeal swabs on day of admission and another one had a high level of IgM and IgG; all had bilateral ground-glass opacities with consolidation on CT chest scan (GGO) and lymphopenia. All patients presented with two or more of the following: fever, cough, malaise, vomiting, and diarrhea with variable duration. However, there were some peculiarities in the clinical presentation. First, there were only 3 to 14 days between the onset of COVID-19 symptoms and the first symptoms of GBS, which developed into flaccid areflexic quadriplegia with glove and stocking hypoesthesia. The second peculiarity was that three of the cases had cranial nerve involvement, suggesting that there may be a high incidence of cranial involvement in SARS-CoV-2-associated GBS. Other peculiarities occurred. Case 2 presented with a cerebellar hemorrhage before symptoms of COVID-19 and had a cardiac attack with elevated cardiac enzymes following onset of GBS symptoms. Case 5 was also unusual in that the onset began with bilateral facial palsy, which preceded the sensory and motor manifestations of GBS (descending course). Neurophysiological studies showed evidence of sensorimotor demyelinating polyradiculoneuropathy, suggesting acute inflammatory polyneuropathy (AIDP) in all patients. Three patients received plasmapheresis. All of them had either full recovery or partial recovery. Possible pathophysiological links between GBS and COVID-19 are discussed.

Abstract
Objective We reviewed the literature on cerebrospinal fluid (CSF) testing in patients with altered olfactory/gustatory function due to COVID-19 for evidence of viral neuroinvasion. Methods We performed a systematic review of Medline and Embase to identify publications that described at least one patient with COVID-19 who had altered olfactory/gustatory function and had CSF testing performed. The search ranged from December 1, 2019 to November 18, 2020. Results We identified 51 publications that described 70 patients who met inclusion criteria. Of 51 patients who had CSF SARS-CoV-2 PCR testing, 3 (6%) patients had positive results and 1 (2%) patient had indeterminate results. Cycle threshold (Ct; the number of amplification cycles required for the target gene to exceed the threshold, which is inversely related to viral load) was not provided for the patients with a positive PCR. The patient with indeterminate results had a Ct of 37 initially, then no evidence of SARS-CoV-2 RNA on repeat testing. Of 6 patients who had CSF SARS-CoV-2 antibody testing, 3 (50%) were positive. Testing to distinguish intrathecal antibody synthesis from transudation of antibodies to the CSF via breakdown of the blood-brain barrier was performed in 1/3 (33%) patients; this demonstrated antibody transmission to the CSF via transudation. Conclusion Detection of SARS-CoV-2 in CSF via PCR or evaluation for intrathecal antibody synthesis appears to be rare in patients with altered olfactory/gustatory function. While pathology studies are needed, our review suggests it is unlikely that these symptoms are related to viral neuroinvasion.

Abstract
BACKGROUND The global spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causing the ongoing coronavirus disease 2019 (COVID-19) pandemic has raised serious concern for patients with chronic disease. A correlation has been identified between the severity of COVID-19 and a patient's preexisting comorbidities. Although COVID-19 primarily involves the respiratory system, dysfunction in multiple organ systems is common, particularly in the cardiovascular, gastrointestinal, immune, renal, and nervous systems. Patients with amyloid transthyretin (ATTR) amyloidosis represent a population particularly vulnerable to COVID-19 morbidity due to the multisystem nature of ATTR amyloidosis. MAIN BODY ATTR amyloidosis is a clinically heterogeneous progressive disease, resulting from the accumulation of amyloid fibrils in various organs and tissues. Amyloid deposition causes multisystem clinical manifestations, including cardiomyopathy and polyneuropathy, along with gastrointestinal symptoms and renal dysfunction. Given the potential for exacerbation of organ dysfunction, physicians note possible unique challenges in the management of patients with ATTR amyloidosis who develop multiorgan complications from COVID-19. While the interplay between COVID-19 and ATTR amyloidosis is still being evaluated, physicians should consider that the heightened susceptibility of patients with ATTR amyloidosis to multiorgan complications might increase their risk for poor outcomes with COVID-19. CONCLUSION Patients with ATTR amyloidosis are suspected to have a higher risk of morbidity and mortality due to age and underlying ATTR amyloidosis-related organ dysfunction. While further research is needed to characterize this risk and management implications, ATTR amyloidosis patients might require specialized management if they develop COVID-19. The risks of delaying diagnosis or interrupting treatment for patients with ATTR amyloidosis should be balanced with the risk of exposure in the health care setting. Both physicians and patients must adapt to a new construct for care during and possibly after the pandemic to ensure optimal health for patients with ATTR amyloidosis, minimizing treatment interruptions.

Abstract
Safety monitoring is of paramount importance for vaccines authorized for emergent use (EUA) by the US Food and Drug Administration (FDA) against SARS-CoV-2. Mass immunization is an essential tool to end the current pandemic, but vaccine surveillance is necessary to identify any potentially associated harms. At the same time, probability of temporal bias should be borne in mind before making conclusions about causality between the vaccine and an attributable undesired effect. We report a case of Guillain-Barré syndrome after the first dose of SARS-CoV-2 vaccine and believe this is a temporal, rather than causal association.

Abstract
Since coronavirus disease-2019 (COVID-19) outbreak in January 2020, several pieces of evidence suggested an association between the spectrum of Guillain-Barré syndrome (GBS) and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Most findings were reported in the form of case reports or case series, whereas a comprehensive overview is still lacking. We conducted a systematic review and searched for all published cases until July 20th 2020. We included 73 patients reported in 52 publications. A broad age range was affected (mean 55, min 11-max 94 years) with male predominance (68.5%). Most patients showed respiratory and/or systemic symptoms, and developed GBS manifestations after COVID-19. However, asymptomatic cases for COVID-19 were also described. The distributions of clinical variants and electrophysiological subtypes resemble those of classic GBS, with a higher prevalence of the classic sensorimotor form and the acute inflammatory demyelinating polyneuropathy, although rare variants like Miller Fisher syndrome were also reported. Cerebrospinal fluid (CSF) albuminocytological dissociation was present in around 71% cases, and CSF SARS-CoV-2 RNA was absent in all tested cases. More than 70% of patients showed a good prognosis, mostly after treatment with intravenous immunoglobulin. Patients with less favorable outcome were associated with a significantly older age in accordance with previous findings regarding both classic GBS and COVID-19. COVID-19-associated GBS seems to share most features of classic post-infectious GBS and possibly the same immune-mediated pathogenetic mechanisms. Nevertheless, more extensive epidemiological studies are needed to clarify these issues.

Abstract
Multiple neurological complications, including Guillain-Barre syndrome (GBS), have been reported in association with the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak. GBS has well-known associations with viruses such as influenza, human immunodeficiency virus, Zika, severe acute respiratory syndrome, Middle East respiratory syndrome, Epstein-Barr virus, and cytomegalovirus. Till date, there have been around 50 distinct published cases of GBS occurring concurrently or shortly after SARS-CoV-2 infection. This report describes the case of a 53-year-old male who presented with bilateral extremity paresthesias two weeks after a positive SARS-CoV-2 test. His symptoms were originally thought to be due to underlying diabetic peripheral neuropathy, but as they progressed, he was eventually diagnosed with SARS-CoV-2-associated GBS. Though GBS may not be a common sequelae of SARS-CoV-2 infection, the prevalence of diabetes mellitus-associated peripheral neuropathy is high enough to warrant awareness and prompt recognition of neurological symptoms that deviate from the baseline in individuals with recent, confirmed SARS-CoV-2 infection.

Abstract
PURPOSE To describe the temporal association of specific acute neurological symptoms in pediatric patients with confirmed SARS-CoV-2 infection between May and August 2020. METHODS We performed a recollection of all the clinical and laboratory data of patients having acute neurological symptoms temporally associated with SARS-CoV-2 infection at a third-level referral hospital in Mexico City (Instituto Nacional de Pediatría). Patients in an age group of 0-17 years with acute neurological signs (including ascending weakness with areflexia, diminished visual acuity, encephalopathy, ataxia, stroke, or weakness with plasma creatinine kinase (CK) elevation) were evaluated. RESULTS Out of 23 patients with neurological manifestations, 10 (43%) had a confirmed SARS-CoV-2 infection. Among the infected patients, 5 (50%) were males aged 2-16 years old (median age 11.8 years old). Four (40%) patients confirmed a close contact with a relative positive for SARS-CoV-2, while 6 (60%) cases had a history of SARS-CoV-2-related symptoms over the previous 2 weeks. The following diagnoses were established: 3 cases of GBS, 2 of ON, 2 of AIS, one of myositis with rhabdomyolysis, one ACA, and one of anti-NMDA-R encephalitis. CONCLUSIONS Neurological manifestations temporally associated with SARS-CoV-2 infection were noticed in the pediatric population even without respiratory symptoms. In this study, 2 of 6 symptomatic patients had mild respiratory symptoms and 4 had unspecific symptoms. During this pandemic, SARS-CoV-2 infection should be considered as etiology in patients with acute neurological symptoms, with or without previous respiratory manifestations, particularly in teenagers.

Abstract
BACKGROUND /Aims: Corona virus disease 2019 (COVID 19) is a pandemic infectious disease of 2020, which often presents with respiratory and gastrointestinal symptoms. The behavior of the virus and its full clinical picture has not been fully studied yet. Many case reports and case series have been running in order to elaborate different presentations and associations. Pulmonary and gastrointestinal features of COVID-19 infection are well outlined; however, neurological manifestations are less defined. CASE PRESENTATION We report two adult cases of COVID-19 infection presented with acute Guillain-Barre Syndrome (GBS), and a literature review on the causal association between COVID-19 and GBS. CONCLUSION Our two case reports in addition to literature review of 116 published cases may help offer insight into the clinical course of COVID-19 infection. Our two COVID-19 patients presented with neurological manifestations of GBS which were not preceded with any respiratory, gastrointestinal or other systemic infection. This leads us to raise the possibility of establish direct causal association between COVID-19 infection and GBS. Physicians should have high clinical suspicions when encounter GBS patient during the current COVID-19 pandemic and consider co-existence of COVID-19 infection that may warrant SARS-CoV-2 testing, isolation precautions, and specific treatment for Covid-19 infection.

Abstract
The diverse clinical manifestations of COVID-19 is emerging as a hallmark of the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection. While the initial target of SARS-CoV-2 is the respiratory tract, it is becoming increasingly clear that there is a complex interaction between the virus and the immune system ranging from mild to controlling responses to exuberant and dysfunctional multi-tissue directed autoimmune responses. The immune system plays a dual role in COVID-19, being implicated in both the anti-viral response and in the acute progression of the disease, with a dysregulated response represented by the marked cytokine release syndrome, macrophage activation, and systemic hyperinflammation. It has been speculated that these immunological changes may induce the loss of tolerance and/or trigger chronic inflammation. In particular, molecular mimicry, bystander activation and epitope spreading are well-established proposed mechanisms to explain this correlation with the likely contribution of HLA alleles. We performed a systematic literature review to evaluate the COVID-19-related autoimmune/rheumatic disorders reported between January and September 2020. In particular, we investigated the cases of incident hematological autoimmune manifestations, connective tissue diseases, antiphospholipid syndrome/antibodies, vasculitis, Kawasaki-like syndromes, acute arthritis, autoimmune-like skin lesions, and neurologic autoimmune conditions such as Guillain–Barré syndrome. We screened 6263 articles and report herein the findings of 382 select reports which allow us to conclude that there are 2 faces of the immune response against SARS-CoV-2, that include a benign virus controlling immune response and a many faceted range of dysregulated multi-tissue and organ directed autoimmune responses that provides a major challenge in the management of this viral disease. The number of cases for each disease varied significantly while there were no reported cases of adult onset Still disease, systemic sclerosis, or inflammatory myositis. The immune system plays a major role in the acute progression of COVID-19. SARS-CoV-2 infection shares features with autoimmune diseases. SARS-CoV-2 can induce Guillain-Barré syndrome, arthritis, chilblain-like lesions.

COVID-19-Associated Guillain-Barre Syndrome: Atypical Para-infectious Profile, Symptom Overlap, and Increased Risk of Severe Neurological Complications. ACTA ACUST UNITED AC 2020; 2:2702-2714. [PMID: 33251483 PMCID: PMC7680081 DOI: 10.1007/s42399-020-00646-w] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/16/2020] [Indexed: 12/11/2022]
Abstract
The concurrence of COVID-19 with Guillain-Barre syndrome (GBS) can increase the likelihood of neuromuscular respiratory failure, autonomic dysfunction, and other life-threatening symptoms. Currently, very little is known about the underlying mechanisms, clinical course, and prognostic implications of comorbid COVID-19 in patients with GBS. We reviewed COVID-19-associated GBS case reports published since the outbreak of the pandemic, with a database search up to August 2020, including a manual search of the reference lists for additional relevant cases. Fifty-one (51) case reports of COVID-19 patients (aged 23–84 years) diagnosed with GBS in 11 different countries were included in this review. The results revealed atypical manifestations of GBS, including para-infectious profiles and onset of GBS without antecedent COVID-19 symptoms. Although all tested patients had signs of neuroinflammation, none had SARS-CoV-2 in the cerebrospinal fluid (CSF), and only four (4) patients had antiganglioside antibodies. The majority had a 1- to 10-day time interval between the onset of COVID-19 and GBS symptoms, and many had a poor outcome, with 20 out of the 51 (39.2%) requiring mechanical ventilation, and two deaths within 12 to 24 h. The atypical manifestations of COVID-19-associated GBS, especially the para-infectious profile and short time interval between the onset of the COVID-19 and GBS symptoms, increase the likelihood of symptom overlap, which can complicate the treatment and result in worsened disease progression and/or higher mortality rates. Inclusion of a neurological assessment during diagnosis of COVID-19 might facilitate timely identification and effective management of the GBS symptoms and improve treatment outcome.

Guillain-Barré syndrome associated with SARS-CoV-2 infection: A systematic review and individual participant data meta-analysis. J Peripher Nerv Syst 2020; 25:335-343. [PMID: 33112450 DOI: 10.1111/jns.12419] [Citation(s) in RCA: 41] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Revised: 10/21/2020] [Accepted: 10/21/2020] [Indexed: 12/15/2022]
Abstract
Several published reports have described a possible association between Guillain-Barré syndrome (GBS) and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. This systematic review aimed to summarize and meta-analyze the salient features and prognosis of SARS-CoV-2-associated GBS. We searched the PubMed (Medline), Web of Science and Cochrane databases for articles published between 01 January 2020 and 05 August 2020 using SARS-CoV-2 and GBS-related keywords. Data on sociodemographic characteristics, antecedent symptoms, clinical, serological and electrophysiological features, and hospital outcomes were recorded. We included 45 articles from 16 countries reporting 61 patients with SARS-CoV-2-associated GBS. Most (97.7%) articles were from high- and upper-middle-income countries. Forty-two (68.9%) of the patients were male; median (interquartile range) age was 57 (49-70) years. Reverse transcriptase polymerase chain reaction for SARS-CoV-2 was positive in 90.2% of patients. One report of SARS-CoV-2-associated familial GBS was found which affected a father and daughter of a family. Albuminocytological dissociation in cerebrospinal fluid was found in 80.8% of patients. The majority of patients (75.5%) had a demyelinating subtype of GBS. Intravenous immunoglobulin and plasmapheresis were given to 92.7% and 7.3% of patients, respectively. Around two-thirds (65.3%) of patients had a good outcome (GBS-disability score ≤ 2) on discharge from hospital. Two patients died in hospital. SARS-CoV-2-associated GBS mostly resembles the classical presentations of GBS that respond to standard treatments. Extensive surveillance is required in low- and lower-middle-income countries to identify and report similar cases/series. Further large-scale case-control studies are warranted to strengthen the current evidence. PROSPERO Registration Number CRD42020201673.

Abstract
Since the initial reports of COVID-19 in December 2019, the world has been gripped by the disastrous acute respiratory disease caused by the SARS-CoV-2 virus. There are an ever-increasing number of reports of neurological symptoms in patients, from severe (encephalitis), to mild (hyposmia), suggesting the potential for neurotropism of SARS-CoV-2. This Perspective investigates the hypothesis that the reliance on self-reporting of hyposmia has resulted in an underestimation of neurological symptoms in COVID-19 patients. While the acute effect of the virus on the nervous system function is vastly overshadowed by the respiratory effects, we propose that it will be important to monitor convalescent individuals for potential long-term implications that may include neurodegenerative sequelae such as viral-associated parkinsonism. As it is possible to identify premorbid harbingers of Parkinson's disease, we propose long-term screening of SARS-CoV-2 cases post-recovery for these expressions of neurodegenerative disease. An accurate understanding of the incidence of neurological complications in COVID-19 requires long-term monitoring for sequelae after remission and a strategized health policy to ensure healthcare systems all over the world are prepared for a third wave of the virus in the form of parkinsonism.
