COVID-19 and neuromuscular disorders

Neurological and Neuropsychiatric Impacts of COVID-19 Pandemic

BACKGROUND

Albeit primarily a disease of respiratory tract, the 2019 coronavirus infectious disease (COVID-19) has been found to have causal association with a plethora of neurological, neuropsychiatric and psychological effects. This review aims to analyze them with a discussion of evolving therapeutic recommendations.

METHODS

PubMed and Google Scholar were searched from 1 January 2020 to 30 May 2020 with the following key terms: "COVID-19", "SARS-CoV-2", "pandemic", "neuro-COVID", "stroke-COVID", "epilepsy-COVID", "COVID-encephalopathy", "SARS-CoV-2-encephalitis", "SARS-CoV-2-rhabdomyolysis", "COVID-demyelinating disease", "neurological manifestations", "psychosocial manifestations", "treatment recommendations", "COVID-19 and therapeutic changes", "psychiatry", "marginalised", "telemedicine", "mental health", "quarantine", "infodemic" and "social media". A few newspaper reports related to COVID-19 and psychosocial impacts have also been added as per context.

RESULTS

Neurological and neuropsychiatric manifestations of COVID-19 are abundant. Clinical features of both central and peripheral nervous system involvement are evident. These have been categorically analyzed briefly with literature support. Most of the psychological effects are secondary to pandemic-associated regulatory, socioeconomic and psychosocial changes.

CONCLUSION

Neurological and neuropsychiatric manifestations of this disease are only beginning to unravel. This demands a wide index of suspicion for prompt diagnosis of SARS-CoV-2 to prevent further complications and mortality.

Crosstalk Between Covid-19 and Associated Neurological Disorders: A Review

COVID-19 is a global pandemic, primarily affecting the pulmonary system but its effects on other systems are not certain. Coronavirus, the causative organism, binds with angiotensinconverting enzyme 2 (ACE2) receptors in the lungs and produces pneumonia-like symptoms. Other than lungs, ACE2 receptors are also seen in the endothelium of blood vessels. Therefore, viruses can bind to the ACE2 that is present in the endothelium of brain blood vessels and thus can invade BBB, leading to neuronal damage. It is also believed that olfactory cells rich in ACE2 receptors may act as the main route of viral spread into various parts of the brain. The reported neurological effects of SARS-CoV-2 include cerebrovascular diseases, ageusia and anosmia, Guillain Barre Syndrome, and viral encephalitis. The extent of neurological involvement in SARS-CoV-2 infection warrants the necessity of further research to systematically classify neurological complications associated with SARS-CoV-2 infection, its diagnosis, and treatment. As ACE2 receptors are present in various other organs, it is obligatory to study the effect of coronavirus on other organs also. Since the long-lasting effects of the COVID-19 are unclear, more studies should be conducted to confirm the effect of the virus on the central nervous system. This review highlights the reported neurological manifestations of SARS-CoV-2 and its mechanism.

COVID-19: Discovery, diagnostics and drug development

Coronavirus disease 2019 (COVID-19) started as an epidemic in Wuhan in 2019, and has since become a pandemic. Groups from China identified and sequenced the virus responsible for COVID-19, named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and determined that it was a novel coronavirus sharing high sequence identity with bat- and pangolin-derived SARS-like coronaviruses, suggesting a zoonotic origin. SARS-CoV-2 is a member of the Coronaviridae family of enveloped, positive-sense, single-stranded RNA viruses that infect a broad range of vertebrates. The rapid release of the sequence of the virus has enabled the development of diagnostic tools. Additionally, serological tests can now identify individuals who have been infected. SARS-CoV-2 infection is associated with a fatality rate of around 1-3%, which is commonly linked to the development of acute respiratory distress syndrome (ARDS), likely resulting from uncontrolled immune activation, the so called "cytokine storm". Risk factors for mortality include advanced age, obesity, diabetes, and hypertension. Drug repurposing has been used to rapidly identify potential treatments for COVID-19, which could move quickly to phase III. Better knowledge of the virus and its enzymes will aid the development of more potent and specific direct-acting antivirals. In the long term, a vaccine to prevent infection is crucial; however, even if successful, it might not be available before 2021-22. To date, except for intravenous remdesivir and dexamethasone, which have modest effects in moderate to severe COVID-19, no strong clinical evidence supports the efficacy of any other drugs against SARS-CoV-2. The aim of this review is to provide insights on the discovery of SARS-CoV-2, its virology, diagnostic tools, and the ongoing drug discovery effort.

Histological findings in skeletal muscle of SARS-CoV2 infected patient

Autopsies represent medical procedures through which the causes of patients' deaths are determined or, through tissue sampling and microscopic examination of slides in usual stains or special tests, one can offer the basis for understanding the physiopathological mechanisms that contribute to the patients' death Histological findings of tissue samples from patients who have died of COVID-19 have been mainly orientated to lung, heart, liver, kidney damage with a small percent of them following other organs, but none has, to our knowledge, studied skeletal muscle.

Neurological implications of COVID-19: a review of the science and clinical guidance

COVID-19 is a significant global health burden. The pulmonary morbidity and mortality of COVID-19 is well described, however, there is mounting evidence of neurological manifestations of SARS-CoV-2, which may be of prognostic significance. This paper summarises the available evidence in order to provide clinicians with a concise summary of the peripheral and central neurological manifestations of COVID-19, discusses specific issues regarding the management of chronic neurological disease in the context of the pandemic, and provides a summary of the thrombotic implications of the disease for the neurologist.

Rapid Implementation of Video Visits in Neurology During COVID-19: Mixed Methods Evaluation

BACKGROUND

Telemedicine has been used for decades. Despite its many advantages, its uptake and rigorous evaluation of feasibility across neurology's ambulatory subspecialties has been sparse. However, the COVID-19 pandemic prompted health care systems worldwide to reconsider traditional health care delivery. To safeguard health care workers and patients, many health care systems quickly transitioned to telemedicine, including across neurology subspecialties, providing a new opportunity to evaluate this modality of care.

OBJECTIVE

To evaluate the accelerated implementation of video visits in ambulatory neurology during the COVID-19 pandemic, we used mixed methods to assess adoption, acceptability, appropriateness, and perceptions of potential sustainability.

METHODS

Video visits were launched rapidly in ambulatory neurology clinics of a large academic medical center. To assess adoption, we analyzed clinician-level scheduling data collected between March 22 and May 16, 2020. We assessed acceptability, appropriateness, and sustainability via a clinician survey (n=48) and semistructured interviews with providers (n=30) completed between March and May 2020.

RESULTS

Video visits were adopted rapidly; overall, 65 (98%) clinicians integrated video visits into their workflow within the first 6 implementation weeks and 92% of all visits were conducted via video. Video visits were largely considered acceptable by clinicians, although various technological issues impacted their satisfaction. Video visits were reported to be more convenient for patients, families, and caregivers than in-person visits; however, access to technology, the patient's technological capacity, and language difficulties were considered barriers. Many clinicians expressed optimism about future utilization of video visits in neurology. They believed that video visits promote continuity of care and can be incorporated into their practice long-term, although several insisted that they can never replace the in-person examination.

CONCLUSIONS

Video visits are an important addition to clinical care in ambulatory neurology and are anticipated to remain a permanent supplement to in-person visits, promoting patient care continuity, and flexibility for patients and clinicians alike.

Quality and Safety Analysis of 2,999 Telemedicine Encounters During the COVID-19 Pandemic

Objective

To examine whether telemedicine remains safe and of high quality despite rapid expansion of services by comparing telemedicine encounters before and during the COVID-19 pandemic.

Methods

Pre-post study investigating 2,999 telemedicine encounters: February 1, 2020-May 15, 2020, was performed. A total of 2,919 completed visits before and after strict social distancing implementation were analyzed for patient and provider characteristics, encounter characteristics (e.g., history and physical examination), and quality and safety metrics (phone calls ≤ 7 days postvisit, visit-cause-specific hospital admission or mortality ≤ 30 days after visit). Stratified analysis of 3 groups for outcomes (young age, neuromuscular diagnosis, and new encounters) was performed.

Results

Patients ranging from 1 month to 33 years of age were seen. Rural patients were less likely to be seen during the pandemic compared with urban patients (8% vs 90%; p < 0.0001); teaching clinic and specialty clinic encounters increased significantly during the pandemic (8% vs 3%; p = 0.005), and documentation of at least 2 systems on examination was noted significantly more frequently during the pandemic (13% vs 7%; p = 0.009). No deaths were reported. There were no differences before/during the pandemic in safety or telemedicine failure metrics within the entire group and high-risk subgroups.

Conclusions

Despite a markedly and rapidly expanded scope of ambulatory telemedicine care during the COVID-19 pandemic, telemedicine remained a safe and high-quality option for pediatric neurology patients. In addition, populations perceived as high risk for telemedicine (the very young, new patients, and those with neuromuscular diagnoses) can benefit from telemedicine visits, particularly when access to in-person care is limited.

The impact of SARS-CoV-2 on skeletal muscles

In 2019-2020, the SARS-CoV-2 pandemic has shocked the world and most health care systems, and a “second wave” of the viral spread is ongoing in Europe and in Italy too. While, at the initial outbreak, the treatment of patients had focused on the respiratory symptoms, many diverse clinical manifestations of the disease have to date been reported. However, the complete course of the disease has not yet been fully clarified. In particular, several reports from the real-world clinical practice have highlighted the noxious effects of SARS-CoV-2 on skeletal muscles. In this brief review, we summarized the main current findings about muscular and neuromuscular damages that may be triggered by the virus or by the drugs used to treat COVID-19. Moreover, we underlined the need of attentive care and vigilance for patients with neuro-muscular disorders, who may be particularly susceptible to infection and at increased risk for severe COVID-19.

What is in the Myopathy Literature?

This update begins with muscle manifestations of coronavirus 2019. They may include myalgias and elevations in serum creatine kinase. It is unknown whether there is direct muscle invasion and how often the critically ill have muscle sequelae. Regarding autoimmune myopathies, a retrospective study of statin-induced necrotizing myopathy is covered. A relatively large proportion of patients had normal strength at presentation. Examples of dermatomyositis associated with immune checkpoint inhibitors are provided including one with cytokine storm. A report of juvenile dermatomyositis with severe abdominal complications is noteworthy. Two articles address unusual associations with inclusion body myositis, namely, spinocerebellar ataxias and granuloma myositis. In the category of muscular dystrophies, a relatively large single center study of the outcome of scapulothoracic arthrodesis for facioscapulohumeral muscular dystrophy is discussed and a article on anoctaminopathies with pauci- or asymptomatic hyperCKemia.

Neuromuscular Diseases Care in the Era of COVID-19

The COVID-19 pandemic has pushed health systems to their limit and forced readjustment of standards of care for different pathologies. Management of neuromuscular diseases becomes a challenge since most of them are chronic, disabling, progressive, and/or require immunosuppressive drugs. There are three main aspects of COVID-19 that affect neuromuscular diseases care. The first one relates to how SARS-CoV2 directly affects different neuromuscular pathologies. Respiratory weakness, as seen in myasthenia gravis, amyotrophic lateral sclerosis, and myopathies, and the use of immunomodulatory drugs (Myasthenia Gravis and Chronic Inflammatory Demyelinating Polyneuropathy) make this group of patients potentially more vulnerable. Secondly, safety measures also affect proper care, limiting care continuity, and physical rehabilitation (one of the essential aspects of myopathies treatment). Telemedicine can partially solve the problem allowing for a continuum of close care, avoiding unnecessary visits, and even guaranteeing the attention of professionals from tertiary care centers. However, one of the crucial steps in neuromuscular diseases is diagnosis, and in most scenarios, more than one face-to-face visit is needed. Lastly, the global COVID-19 situation will also have an economic impact on patients and their families. This situation is of particular concern given that neuromuscular diseases already present difficulties due to the scarcity of resources in terms of public healthcare and research.

Assessment of neurological manifestations in hospitalized patients with COVID-19

BACKGROUND AND PURPOSE

The objective of this study was to assess the neurological manifestations in a series of consecutive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive patients, comparing their frequency with a population hospitalized in the same period for flu/respiratory symptoms, finally not related to SARS-CoV-2.

METHODS

Patients with flu/respiratory symptoms admitted to Fondazione Policlinico Gemelli hospital from 14 March 2020 to 20 April 2020 were retrospectively enrolled. The frequency of neurological manifestations of patients with SARS-CoV-2 infection was compared with a control group.

RESULTS

In all, 213 patients were found to be positive for SARS-CoV-2, after reverse transcriptase polymerase chain reaction on nasal or throat swabs, whilst 218 patients were found to be negative and were used as a control group. Regarding central nervous system manifestations, in SARS-CoV-2-positive patients a higher frequency of headache, hyposmia and encephalopathy always related to systemic conditions (fever or hypoxia) was observed. Furthermore, muscular involvement was more frequent in SARS-CoV-2 infection.

CONCLUSIONS

Patients with COVID-19 commonly have neurological manifestations but only hyposmia and muscle involvement seem more frequent compared with other flu diseases.

Non-respiratory presentations of COVID-19, a clinical review

INTRODUCTION

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 or COVID-19) is a highly infectious viral syndrome currently threatening millions of people worldwide. It is widely recognized as a disease of the pulmonary system, presenting with fever, cough, and shortness of breath. However, a number of extrapulmonary manifestations have been described in the literature.

OBJECTIVE

In this review, we seek to provide a comprehensive summary of the hematologic, gastroenterological, renal, dermatologic, neurologic, and psychiatric manifestations of COVID-19.

DISCUSSION

Hematological presentations of COVID-19 include laboratory abnormalities such as decreased total lymphocyte count, prolonged prothrombin time (PT), elevated d-dimer, and increased lactate dehydrogenase (LDH). Several of these findings are associated with increased mortality among infected patients. The most common gastrointestinal symptoms include nausea, vomiting, diarrhea, and abdominal pain. Furthermore, presence of viral RNA in patient stool suggests the possibility of additional testing modalities for COVID-19. Nephrological findings such as proteinuria, hematuria, and elevated BUN and creatinine levels have been observed. Additionally, several studies demonstrated that patients with COVID-19 who developed acute kidney injury (AKI) had a greater risk of mortality. The virus can also present with cutaneous symptoms such as erythematous rashes, urticaria, and chicken pox-like lesions. Neuropsychiatric symptoms have been described in the literature, and patients can exhibit findings consistent with viral encephalitis, cerebral vascular disease, peripheral nerve disorders, and psychosis.

CONCLUSION

Although COVID-19 does usually present primarily with respiratory symptoms, the extra-pulmonary manifestations of the virus are unpredictable and varied. Better understanding and awareness of these symptoms can lead to more efficient diagnosis, rapid treatment, isolation, and decreased spread of the disease.

Side Effects of Chloroquine and Hydroxychloroquine on Skeletal Muscle: a Narrative Review

Purpose of Review

Concerning adverse neuromuscular effects, there are quite a few reports about the incidence and prevalence of chloroquine (CQ) and hydroxychloroquine (HCQ) myopathy. Given the above, I decided to explore the relationships of these drugs with skeletal muscle in an attempt to clarify how they affect the muscle now and in the future, as millions of people are using CQ and HCQ.

Recent Findings

The literature review identified 28 publications about CQ/HCQ myopathy, totaling 56 patients, from 1963 to 2020. A compilation of all patients was carried out by computing demographic features, clinical aspects, laboratory exams, and clinical evolution. All articles but two represented a large series about incidence and prevalence of the myopathy. Fifty-nine percent used QC, mean daily dose was 393 mg per day, and mean duration of treatment was 37 months. The predominant underlying diseases were rheumatoid arthritis (42.8%) and lupus erythematosus (26.8%). Respiratory distress was present in 12.5% in patients with proximal muscle weakness (87.2%). Dysphagia and cervical and axial weakness were observed in a smaller percentage. Creatine kinase was elevated in 60.7%, and EMG showed a myopathic pattern in 54%. Muscle biopsy showed a vacuolar pattern in 53.7%, and curvilinear bodies (CB) were the predominant ultrastructural finding (86.8%). After drug withdrawal, 85.4% of patients improved, and 12.7% died from other causes than myopathy.

Summary

CQ and HCQ myopathy has been known for a long time, but the incidence is low, being described only with long-term use. The use of these drugs for a short period has not been reported, although a prolonged elimination half-life of these drugs actually exists.

Telemedicine review in neuro-oncology: comparative experiential analysis for Barrow Neurological Institute and Geisinger Health during the 2020 COVID-19 pandemic

Coronavirus disease 2019 (COVID-19) has grossly affected how we deliver health care and how health care institutions derive value from the care provided. Adapting to new technologies and reimbursement patterns were challenges that had to be met by the institutions while patients struggled with decisions to prioritize concerns and to identify new pathways to care. With the implementation of social distancing practices, telemedicine plays an increasing role in patient care delivery, particularly in the field of neurology. This is of particular concern in our cancer patient population given that these patients are often at increased infectious risk on immunosuppressive therapies and often have mobility limitations. We reviewed telemedicine practices in neurology pre- and post-COVID-19 and evaluated the neuro-oncology clinical practice approaches of 2 large care systems, Barrow Neurological Institute and Geisinger Health. Practice metrics were collected for impact on clinic volumes, institutional recovery techniques, and task force development to address COVID-19 specific issues. Neuro-Oncology divisions reached 67% or more of prepandemic capacity (patient visits and slot utilization) within 3 weeks and returned to 90% or greater capacity within 6 weeks of initial closures due to COVID-19. The 2 health systems rapidly and effectively implemented telehealth practices to recover patient volumes. Although telemedicine will not replace the in-person clinical visit, telemedicine will likely continue to be an integral part of neuro-oncologic care. Telemedicine has potential for expanding access in remote areas and provides a convenient alternative to patients with limited mobility, transportation, or other socioeconomic complexities that otherwise challenge patient visit adherence.

Description of 3 patients with myasthenia gravis and COVID-19

BACKGROUND

The COVID-19 pandemic presents two main concerns for patients with myasthenia gravis (MG); chronic immunosuppression may put them at greater risk, and some proposed treatments for COVID-19 could cause MG exacerbation.

CASE DESCRIPTION

We present three patients with generalized seropositive MG who developed COVID-19. All patients had a favorable outcome, with only one patient experiencing exacerbation. In this case, exacerbation began before COVID-19; she required ICU admission, non-invasive ventilatory support, and received hydroxychloroquine, lopinavir and ritonavir which were well tolerated. One patient received IVIG in place of scheduled plasma exchange.

CONCLUSION

Outcome was favorable in all cases despite immunosuppressive therapy, use of experimental COVID-19 medication and switching of plasma exchange for IVIG.

New onset of ocular myasthenia gravis in a patient with COVID-19: a novel case report and literature review

The novel coronavirus outbreak of SARS-CoV-2 first began in Wuhan, China, in December 2019. The most striking manifestation of SARS-CoV-2 is atypical pneumonia and respiratory complications; however, various neurological manifestations are now well recognized. Currently, there have been very few case reports regarding COVID-19 in patients with a known history of myasthenia gravis. Myasthenia gravis (MG) causes muscle weakness, especially respiratory muscles, in high-risk COVID-19 patients, which can lead to severe respiratory compromise. There are few reported cases of severe myasthenia crisis following COVID-19, likely due to the involvement of the respiratory apparatus and the use of immunosuppressive medication. We report the first case of ocular MG developing secondary to COVID-19 infection in a 65-year-old woman. Two weeks prior to hospitalization, the patient suffered from cough, fever, and diarrhea and was found to be positive for COVID-19 via a nasopharyngeal RT-PCR swab test. The electrodiagnostic test showed decremental response over more than 10% on repetitive nerve stimulation test of orbicularis oculi. She tested positive for antibodies against acetylcholine receptor. COVID-19 is known to cause the release of inflammatory cytokines, leading to immune-mediated damage. MG is an immune-mediated disorder caused by molecular mimicry and autoantibodies against the neuromuscular junction.

Neuropsychiatric aspects of COVID-19 pandemic: A selective review

Corona virus disease (COVID-19) has been declared as a controllable pandemic by the World Health Organization (WHO). COVID-19 though is a predominantly respiratory illness; it can also affect brain and other organs like kidneys, heart and liver. Neuropsychiatric manifestations are common during viral pandemics but are not effectively addressed. Fever and cough are common symptoms only in infected individuals but headache and sleep disturbances are common even in uninfected general public. In this selective review, the authors report the available evidence of neuropsychiatric morbidity during the current COVID-19 crisis. The authors also discuss the postulated neuronal mechanisms of the corona virus infection sequelae.

Facing acute neuromuscular diseases during COVID-19 pandemic: focus on Guillain-Barré syndrome

In December 2019, a cluster of cases with 2019 Novel Coronavirus pneumonia from Wuhan, China, aroused worldwide concern due to an escalating outbreak in all the countries in the world. Coronavirus belongs to a family of single-stranded RNA viruses, which includes severe acute respiratory syndrome (SARS-CoV) and Middle East respiratory syndrome (MERS-CoV), that have caused human epidemics with high fatality. The spectrum of the novel coronavirus disease (SARS-Co-2 or COVID-19) ranges from asymptomatic infections to fatal pneumonia, and differs from other viral pulmonary infections. MERS-CoV is known to be potentially neuroinvasive. Extensive reports from China documented central and peripheral nervous system involvement in patients with COVID-19, and identified in angiotensin converting enzyme2 (ACE2), which is present in multiple human organs, the functional receptor for this virus. Guillain-Barré syndrome (GBS) has recently been associated to COVID-19 rising concern among physicians. This review summarizes the current state of knowledge on GBS during or after COVID-19 infection, attempting to clarify the pathophysiology of the associated respiratory dysfunction and failure.

Neurological manifestations of severe acute respiratory syndrome coronavirus 2-a controversy 'gone viral'

Severe acute respiratory syndrome coronavirus 2 first appeared in December 2019 in Wuhan, China, and developed into a worldwide pandemic within the following 3 months causing severe bilateral pneumonia (coronavirus disease 2019) with in part fatal outcomes. After first experiences and tentative strategies to face this new disease, several cases were published describing severe acute respiratory syndrome coronavirus 2 infection related to the onset of neurological complaints and diseases such as, for instance, anosmia, stroke or meningoencephalitis. Of note, there is still a controversy about whether or not there is a causative relation between severe acute respiratory syndrome coronavirus 2 and these neurological conditions. Other concerns, however, seem to be relevant as well. This includes not only the reluctance of patients with acute neurological complaints to report to the emergency department for fear of contracting severe acute respiratory syndrome coronavirus 2 but also the ethical and practical implications for neurology patients in everyday clinical routine. This paper aims to provide an overview of the currently available evidence for the occurrence of severe acute respiratory syndrome coronavirus 2 in the central and peripheral nervous system and the neurological diseases potentially involving this virus.

Myasthenia Gravis and COVID-19: Clinical Characteristics and Outcomes

Myasthenia gravis (MG), an autoimmune neuromuscular disorder, may be a risk factor for severe COVID-19. We conducted an observational retrospective study with 15 consecutive adult MG patients admitted with COVID-19 at four hospitals in São Paulo, Brazil. Most patients with MG hospitalized for COVID-19 had severe courses of the disease: 87% were admitted in the intensive care unit, 73% needed mechanical ventilation, and 30% died. Immunoglobulin use and the plasma exchange procedure were safe. Immunosuppressive therapy seems to be associated with better outcomes, as it might play a protective role.

Neurological manifestations in COVID-19: A narrative review

COVID-19, a respiratory viral infection, has affected more than 10 million individuals worldwide. Common symptoms include fever, dry cough, fatigue and shortness of breath. Some patients show neurological manifestations such as headache, dizziness, cerebrovascular disease, peripheral nerve and muscle symptoms and smell and taste impairment. In previous studies, SARS-CoV-1 and MERS-CoV were found to affect the nervous system. Given the high similarity between SARS-CoV-1 and SARS-CoV-2, effects on the nervous system by SARS-CoV-2 are a possibility. We have outlined the common neurological manifestations in COVID-19 (information are up-to-date as of June 2020) and discussed the possible pathogenetic mechanisms and management options.

Neurological immunotherapy in the era of COVID-19 - looking for consensus in the literature

The coronavirus disease 2019 (COVID-19) pandemic is concerning for patients with neuroimmunological diseases who are receiving immunotherapy. Uncertainty remains about whether immunotherapies increase the risk of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or increase the risk of severe disease and death upon infection. National and international societies have developed guidelines and statements, but consensus does not exist in several areas. In this Review, we attempt to clarify where consensus exists and where uncertainty remains to inform management approaches based on the first principles of neuroimmunology. We identified key questions that have been addressed in the literature and collated the recommendations to generate a consensus calculation in a Delphi-like approach to summarize the information. We summarize the international recommendations, discuss them in light of the first available data from patients with COVID-19 receiving immunotherapy and provide an overview of management approaches in the COVID-19 era. We stress the principles of medicine in general and neuroimmunology in particular because, although the risk of viral infection has become more relevant, most of the considerations apply to the general management of neurological immunotherapy. We also give special consideration to immunosuppressive treatment and cell-depleting therapies that might increase susceptibility to SARS-CoV-2 infection but reduce the risk of severe COVID-19.

COVID-19 Presentation in Association with Myasthenia Gravis: A Case Report and Review of the Literature

Currently, there are scarce data on how COVID-19 affects people with myasthenia gravis. Theoretically, there is a higher risk of experiencing severe manifestations of COVID-19 due to the common use of immunosuppressive drugs and potential respiratory failure in relation to respiratory muscle weakness. This is one of the early cases of COVID-19 reported in association with myasthenia gravis. Here, we highlight the prognosis, discuss the pathophysiological mechanisms, and prompt the consideration of convalescent plasma therapy in myasthenia gravis patients with concomitant COVID-19.

Challenges and management of neurological and psychiatric manifestations in SARS-CoV-2 (COVID-19) patients

COVID-19 is a pandemic caused by human coronavirus (HCoV) SARS-CoV-2, which originated in Wuhan, China, at the end of 2019 and spread globally during 2020. Due to the difficulty of clinical decision-making during this period, our study group reviewed current literature focusing on the neurological and psychiatric aspects of COVID-19. Despite the knowledge on this newly discovered virus which is constantly evolving, different pieces of evidence reported an association between COVID-19 and neurological symptoms like headache, dizziness, taste and smell disorders and complications involving the nervous system eventually triggered by the pathologic processes elicited by SARS-CoV-2. It seems that younger patients are less prone to develop severe forms of COVID-19. However, neurological signs have been reported in paediatric patients as well, and in some cases, the infection presented neurological sequelae. Furthermore, children with particular neurological diseases or treated with specific drugs (e.g. immune-suppressant therapies) must be carefully monitored during this pandemic. Neurologists should be aware of the main drug–drug interactions and the neurological side effects of COVID-19 treatments. Notably, adverse mental health impact has been reported in patients with SARS-CoV-2, which could be related either to the social strain or to the eventual neurotropic effects of the virus, which in other infections have been proven to promote the onset of psychiatric symptoms. Further, psychiatric population may be more vulnerable to the infection and at higher risk for adverse outcomes.

Severe rapidly progressive Guillain-Barré syndrome in the setting of acute COVID-19 disease

There is concern that the global burden of coronavirus disease of 2019 (COVID-19) due to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection might yield an increased occurrence of Guillain-Barré syndrome (GBS). It is currently unknown whether concomitant SARS-CoV-2 infection and GBS are pathophysiologically related, what biomarkers are useful for diagnosis, and what is the optimal treatment given the medical comorbidities, complications, and simultaneous infection. We report a patient who developed severe GBS following SARS-CoV-2 infection at the peak of the initial COVID-19 surge (April 2020) in New York City and discuss diagnostic and management issues and complications that may warrant special consideration in similar patients.

The Role of Health Preconditions on COVID-19 Deaths in Portugal: Evidence from Surveillance Data of the First 20293 Infection Cases

BACKGROUND

It is essential to study the effect of potential co-factors on the risk of death in patients infected by COVID-19. The identification of risk factors is important to allow more efficient public health and health services strategic interventions with a significant impact on deaths by COVID-19. This study aimed to identify factors associated with COVID-19 deaths in Portugal.

METHODS

A national dataset with the first 20,293 patients infected with COVID-19 between 1 January and 21 April 2020 was analyzed. The primary outcome measure was mortality by COVID-19, measured (registered and confirmed) by Medical Doctors serving as health delegates on the daily death registry. A logistic regression model using a generalized linear model was used for estimating Odds Ratio (OR) with 95% confidence intervals (95% CI) for each potential risk indicator.

RESULTS

A total of 502 infected patients died of COVID-19. The risk factors for increased odds of death by COVID-19 were: sex (male: OR = 1.47, ref = female), age ((56-60) years, OR = 6.01; (61-65) years, OR = 10.5; (66-70) years, OR = 20.4; (71-75) years, OR = 34; (76-80) years, OR = 50.9; (81-85) years, OR = 70.7; (86-90) years, OR = 83.2; (91-95) years, OR = 91.8; (96-104) years, OR = 140.2, ref = (0-55)), Cardiac disease (OR = 2.86), Kidney disorder (OR = 2.95), and Neuromuscular disorder (OR = 1.58), while condition (None (absence of precondition); OR = 0.49) was associated with a reduced chance of dying after adjusting for other variables of interest.

CONCLUSIONS

Besides age and sex, preconditions justify the risk difference in mortality by COVID-19.

Spectrum of Neurological Manifestations in Covid-19: A Review

COVID-19, in most patients, presents with mild flu-like illness. Elderly patients with comorbidities, like hypertension, diabetes, or lung and cardiac disease, are more likely to have severe disease and deaths. Neurological complications are frequently reported in severely or critically ill patients with comorbidities. In COVID-19, both central and peripheral nervous systems can be affected. The SARS-CoV-2 virus causes the disease COVID-19 and has the potential to invade the brain. The SARS-CoV-2 virus enters the brain either via a hematogenous route or olfactory system. Angiotensin-converting enzyme two receptors, present on endothelial cells of cerebral vessels, are a possible viral entry point. The most severe neurological manifestations, altered sensorium (agitation, delirium, and coma), are because of hypoxic and metabolic abnormalities. Characteristic cytokine storm incites severe metabolic changes and multiple organ failure. Profound coagulopathies may manifest with ischemic or hemorrhagic stroke. Rarely, SARS-CoV-2 virus encephalitis or pictures like acute disseminated encephalomyelitis or acute necrotizing encephalopathy have been reported. Nonspecific headache is a commonly experienced neurological symptom. A new type of headache "personal protection equipment-related headache" has been described. Complete or partial anosmia and ageusia are common peripheral nervous system manifestations. Recently, many cases of Guillain-Barré syndrome in COVID-19 patients have been observed, and a postinfectious immune-mediated inflammatory process was held responsible for this. Guillain-Barré syndrome does respond to intravenous immunoglobulin. Myalgia/fatigue is also common, and elevated creatine kinase levels indicate muscle injury. Most of the reports about neurological complications are currently from China. COVID-19 pandemic is spreading to other parts of the world; the spectrum of neurological complications is likely to widen further.

Teleneurology during the COVID-19 pandemic: A step forward in modernizing medical care

BACKGROUND

The COVID-19 pandemic mandated rapid transition from face-to-face encounters to teleneurology visits. While teleneurology is regularly used in acute stroke care, its application in other branches of neurology was limited. Here we review how the recent pandemic has created a paradigm shift in caring for patients with chronic neurological disorders and how academic institutions have responded to the present need.

METHOD

Literature review was performed to examine the recent changes in health policies. Number of outpatient visits and televisits in the Department of Neurology was reviewed from Yale University School of Medicine and Johns Hopkins School of Medicine to examine the road to transition to televisit.

RESULTS

The federal government and the insurance providers extended their supports during the COVID-19 pandemic. Several rules and regulations regarding teleneurology were revised and relaxed to address the current need. New technologies for video conferencing were incorporated. The transition to televisits went smoothly in both the institutions and number of face-to-face encounters decreased dramatically along with a rapid rise in televisits within 2 weeks of the declaration of national emergency.

CONCLUSION AND RELEVANCE

The need for "social distancing" during the COVID-19 pandemic has created a major surge in the number of teleneurology visits, which will probably continue for the next few months. It may have initiated a more permanent transition to virtual technology incorporated medical care.

The neurology of COVID-19 revisited: A proposal from the Environmental Neurology Specialty Group of the World Federation of Neurology to implement international neurological registries

A comprehensive review of the neurological disorders reported during the current COVID-19 pandemic demonstrates that infection with SARS-CoV-2 affects the central nervous system (CNS), the peripheral nervous system (PNS) and the muscle. CNS manifestations include: headache and decreased responsiveness considered initial indicators of potential neurological involvement; anosmia, hyposmia, hypogeusia, and dysgeusia are frequent early symptoms of coronavirus infection. Respiratory failure, the lethal manifestation of COVID-19, responsible for 264,679 deaths worldwide, is probably neurogenic in origin and may result from the viral invasion of cranial nerve I, progressing into rhinencephalon and brainstem respiratory centers. Cerebrovascular disease, in particular large-vessel ischemic strokes, and less frequently cerebral venous thrombosis, intracerebral hemorrhage and subarachnoid hemorrhage, usually occur as part of a thrombotic state induced by viral attachment to ACE2 receptors in endothelium causing widespread endotheliitis, coagulopathy, arterial and venous thromboses. Acute hemorrhagic necrotizing encephalopathy is associated to the cytokine storm. A frontal hypoperfusion syndrome has been identified. There are isolated reports of seizures, encephalopathy, meningitis, encephalitis, and myelitis. The neurological diseases affecting the PNS and muscle in COVID-19 are less frequent and include Guillain-Barré syndrome; Miller Fisher syndrome; polyneuritis cranialis; and rare instances of viral myopathy with rhabdomyolysis. The main conclusion of this review is the pressing need to define the neurology of COVID-19, its frequency, manifestations, neuropathology and pathogenesis. On behalf of the World Federation of Neurology we invite national and regional neurological associations to create local databases to report cases with neurological manifestations observed during the on-going pandemic. International neuroepidemiological collaboration may help define the natural history of this worldwide problem.

Along with a description of clinical manifestations, pathogenesis, methods of laboratory, instrumental and radiological diagnosis with the discussion of the nosological forms. An interdisciplinary approach and international cooperation are required to study the problems pathogenesis, course, outcomes, and the development of new methods of diagnosis and treatment.

Significant reduction of physical activity in patients with neuromuscular disease during COVID-19 pandemic: the long-term consequences of quarantine

Background

Quarantine was the measure taken by governments to control the rapid spread of COVID-19. This restriction resulted in a sudden change in people’s lifestyle, leading to an increase in sedentary behavior and a related decrease in the practice of physical activity (PA). However, in neuromuscular diseases patients need to perform regular PA to counteract the negative consequences of the disease. Hence, the aim of this study was to estimate the levels of PA, measured as energy expenditure (MET–minute/week), among patients with neuromuscular disease (NMD) before and during the last week of quarantine.

Methods

A total of 268 Italian subjects, living in Sicily, completed an adapted version of the IPAQ-SF. Participants comprised 149 NMD, enrolled at the Neuromuscular Clinic of Palermo and 119 healthy subjects (control group). The SF-12 questionnaire was also administered to NMD. The Mann–Whitney U and the Kruskal–Wallis rank-sum tests were used for statistical analyses.

Results

We observed a significant decrease of the total weekly PA level during COVID-19 quarantine in both patients and controls. Moreover, a significant difference in the total weekly PA level was found depending on the presence of neuromuscular disease, impaired walking, gender and BMI. Finally, we found a correlation between SF-12 scores and the entity of the reduction of PA level during quarantine, thus confirming a relevant association with the quality of life in NMD.

Conclusion

Our study confirmed that COVID-19 quarantine has affected the practice of PA among both NMD and healthy controls.

Tales of a department: how the COVID-19 pandemic transformed Detroit's Henry Ford Hospital, Department of Neurology-part I: the surge

The COVID-19 pandemic has reshaped the way healthcare systems operate around the world. The major hurdles faced have been availability of personal protective equipment, intensive care unit beds, ventilators, treatments and medical personnel. Detroit, Michigan has been an epidemic ‘hotspot’ in the USA with Wayne County among the hardest hit counties in the nation. The Department of Neurology at Henry Ford Hospital, in the heart of Detroit, has responded effectively to the pandemic by altering many aspects of its operations. The rapid engagement of the department and enhanced utilisation of teleneurology were two of the pivotal elements in the successful response to the pandemic. In this review, we describe the transformation our department has undergone, as it relates to its infrastructure redesigning, coverage restructuring, redeployment strategies, medical education adaptations and novel research initiatives.

Accelerated launch of video visits in ambulatory neurology during COVID-19: Key lessons from the Stanford experience

The SARS-CoV-2 (COVID-19) pandemic has rapidly moved telemedicine from discretionary to necessary. Here, we describe how the Stanford Neurology Department (1) rapidly adapted to the COVID-19 pandemic, resulting in over 1,000 video visits within 4 weeks, and (2) accelerated an existing quality improvement plan of a tiered roll out of video visits for ambulatory neurology to a full-scale roll out. Key issues we encountered and addressed were related to equipment/software, provider engagement, workflow/triage, and training. On reflection, the key drivers of our success were provider engagement and dedicated support from a physician champion, who plays a critical role understanding stakeholder needs. Before COVID-19, physician interest in telemedicine was mixed. However, in response to county and state stay-at-home orders related to COVID-19, physician engagement changed completely; all providers wanted to convert a majority of visits to video visits as quickly as possible. Rapid deployment of neurology video visits across all its subspecialties is feasible. Our experience and lessons learned can facilitate broader utilization, acceptance, and normalization of video visits for neurology patients in the present as well as the much anticipated postpandemic era.

The care of patients with Duchenne, Becker, and other muscular dystrophies in the COVID-19 pandemic

The coronavirus disease 2019 (COVID-19) pandemic has resulted in the reorganization of health-care settings affecting clinical care delivery to patients with Duchenne and Becker muscular dystrophy (DBMD) as well as other inherited muscular dystrophies. The magnitude of the impact of this public health emergency on the care of patients with DBMD is unclear as they are suspected of having an increased risk for severe manifestations of COVID-19. In this article, the authors discuss their consensus recommendations pertaining to care of these patients during the pandemic. We address issues surrounding corticosteroid and exon-skipping treatments, cardiac medications, hydroxychloroquine use, emergency/respiratory care, rehabilitation management, and the conduct of clinical trials. We highlight the importance of collaborative treatment decisions between the patient, family, and health-care provider, considering any geographic or institution-specific policies and precautions for COVID-19. We advocate for continuing multidisciplinary care for these patients using telehealth.

Neurology and COVID-19: Acting now. Preparing for Future

COVID-19 has a wide-ranging and multimodal neurological impact. First, several neurological symptoms and complications are commonly observed in patients with COVID-19. Second, medications and vaccinations used to counter the disease can have secondary neurological effects. Third, patients with pre-existing neurological disorders bear an increased health-risk due to COVID-19. And finally, the pandemic has disrupted the delivery of neurological and vaccination services, and associated educational and research programs. In this article we review the various channels through which the pandemic is known or projected to effect individual patients or the practice of neurology. We also provide recommendations to manage its immediate effects and prepare for the longer-term fall-out.

Impact of the COVID-19 pandemic on headache management in Spain: an analysis of the current situation and future perspectives

Introduction

The COVID-19 pandemic has had a great impact on healthcare systems. Spain, where headache is the main reason for outpatient neurology consultation, is one of the countries with the most reported cases of the disease.

Objectives

This study aimed to analyse the impact of the COVID-19 pandemic on headache units in Spain and to evaluate how neurologists see the future of these units.

Methods

We conducted a cross-sectional online survey of headache units during the sixth week of the state of alarm declared in Spain in response to the pandemic.

Results

The response rate was 74%, with the participation of centres with different characteristics and from all Autonomous Communities of Spain. Limitations in face-to-face activity were reported by 95.8% of centres, with preferential face-to-face consultation being maintained in 60.4%, and urgent procedures in 45.8%. In 91.7% of centres, the cancelled face-to-face activity was replaced by telephone consultation. 95.8% of respondents stated that they would use personal protection equipment in the future, and 86% intended to increase the use of telemedicine. The majority foresaw an increase in waiting lists (93.8% for initial consultations, 89.6% for follow-up, and 89.4% for procedures) and a worse clinical situation for patients, but only 15% believed that their healthcare structures would be negatively affected in the future.

Conclusions

As a consequence of the pandemic, headache care and research activity has reduced considerably. This demonstrates the need for an increase in the availability of telemedicine in our centres in the near future.

Neurological features of COVID-19 and their treatment: a review

Severe acute respiratory syndrome-correlated new coronavirus (SARS-Cov-2) infection may result in neurological signs and symptoms through different mechanisms. Although direct infection of the central nervous system is uncertain or very rare and the para-infectious complications (e.g. inflammatory neuropathies) are rare, delirium and septic encephalopathy are common in severely ill patients. Smell dysfunction and headache are very common in mild cases, especially in younger people and females. Muscle pain is common in both mild and severe cases, and in the most compromised patients, it is accompanied by increased creatine kinase levels and by a likely true myopathic damage. Ischemic stroke has been reported as a possible complication of the hypercoagulability associated with severe SARS-Cov-2 infection, but further studies are needed. Most of the neurological manifestations may occur early in the illness. Therefore, during the pandemic period, neurologists need to be involved, alert, and prepared. Neurological practice will not be the same until a vaccine is available.

Ethical decision-making for children with neuromuscular disorders in the COVID-19 crisis

The sudden appearance and proliferation of coronavirus disease 2019 has forced societies and governmental authorities across the world to confront the possibility of resource constraints when critical care facilities are overwhelmed by the sheer numbers of grievously ill patients. As governments and health care systems develop and update policies and guidelines regarding the allocation of resources, patients and families affected by chronic disabilities, including many neuromuscular disorders that affect children and young adults, have become alarmed at the possibility that they may be determined to have less favorable prognoses due to their underlying diagnoses and thus be assigned to lower priority groups. It is important for health care workers, policymakers, and government officials to be aware that the long-term prognoses for children and young adults with neuromuscular disorders are often more promising than previously believed due to a better understanding of the natural history of these diseases, benefits of multidisciplinary supportive care, and novel molecular therapies that can dramatically improve the disease course. Although the realities of a global pandemic have the potential to require a shift from our usual, highly individualistic standards of care to crisis standards of care, shifting priorities should nonetheless be informed by good facts. Resource allocation guidelines with the potential to affect children and young adults with neuromuscular disorders should take into account the known trajectory of acute respiratory illness in this population and rely primarily on contemporary long-term outcome data.

Estimating the impact of COVID-19 pandemic on services provided by Italian Neuromuscular Centers: an Italian Association of Myology survey of the acute phase

Introduction

Since February 2020, the outbreak of COVID-19 in Italy has forced the health care system to undergo profound rearrangements in its services and facilities, especially in the worst-hit areas in Northern Italy. In this setting, inpatient and outpatient services had to rethink and reorganize their activities to meet the needs of patients during the “lockdown”. The Italian Association of Myology developed a survey to estimate the impact of these changes on patients affected by neuromuscular disorders and on specialized neuromuscular centers during the acute phase of COVID-19 pandemic.

Methods

We developed an electronic survey that was sent to neuromuscular centers affiliated with the Italian Association of Myology, assessing changes in pharmacological therapies provision, outpatient clinical and instrumental services, support services (physiotherapy, nursing care, psychological support) and clinical trials.

Results

40% of surveyed neuromuscular centers reported a reduction in outpatient visit and examinations (44.5% of centers in Northern regions; 25% of centers in Central regions; 50% of centers in Southern regions). Twenty-two% of centers postponed in-hospital administration of therapies for neuromuscular diseases (23.4% in Northern regions; 13.0% in Central regions; 20% in Southern regions). Diagnostic and support services (physiotherapy, nursing care, psychological support) were suspended in 57% of centers (66/43/44% in Northern, Central and Southern centers respectively) Overall, the most affected services were rehabilitative services and on-site outpatient visits, which were suspended in 93% of centers. Strategies adopted by neuromuscular centers to overcome these changes included maintaining urgent on-site visits, addressing patients to available services and promoting remote contact and telemedicine.

Conclusions

Overall, COVID-19 pandemic resulted in a significant disruption of clinical and support services for patients with neuromuscular diseases. Despite the efforts to provide telemedicine consults to patients, this option could be promoted and improved further. A close collaboration between the different neuromuscular centers and service providers as well as further implementation of telehealth platforms are necessary to ensure quality care to NMD patients in the near future and in case of recurrent pandemic waves.
