Management challenges for chronic dysimmune neuropathies during the COVID-19 pandemic

Physical Activity in Patients with Neuromuscular Disease Three Years after COVID-19, a Longitudinal Survey: The After-Effects of the Quarantine and the Benefits of a Return to a Healthier Life-Style

BACKGROUND

Quarantine was one of the strategies adopted by governments against the spread of COVID-19. This restriction has caused an increase in sedentary behaviors and a decrease in the practice of physical activity (PA), with a consequent negative impact on lifestyle both in healthy people and in those who need constant practice of PA to combat diseases, such as patients suffering from neuromuscular diseases (NMDs). Hence, this study aimed to compare PA levels among patients with NMD during and after quarantine.

METHODS

An adapted version of the International Physical Activity Questionnaire Short-Form and the Short-Form Health Survey were administered during COVID-19 quarantine (T0) and after 3 years (T1) to 91 Italian patients with NMDs.

RESULTS

We found a significant increase in the total PA level at T1, with no significant changes in vigorous-intensity PA. Moreover, a significant decrease in the PA level was found among the patients with different NMDs. No significant changes in physical component scores and mental component scores were detected.

CONCLUSIONS

Our results suggest that it would be necessary to provide alternative indoor exercise settings to prevent the adoption of sedentary behaviors.

Current clinical management of CIDP with immunoglobulins in France: An expert opinion

Treatment strategies in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) must be adapted on a case-to-case basis. Validated and reproducible tools for monitoring treatment response are required at diagnosis, when initiating treatment and throughout follow-up. A task force of French neurologists, experts in neuromuscular disease reference centers, was assembled to provide expert advice on the management of typical CIDP with intravenous immunoglobulins (Ig), and to harmonize treatment practices in public and private hospitals. The task force also referred to the practical experience of treating CIDP with Ig at the diagnostic, induction and follow-up stages, including the assessment and management of Ig dependence, and following the recommendations of the French health agency.

Reduction of Infusion Time Using a 10% Intravenous Immunoglobulin Formulation With a 15-Minute Rate Escalation Protocol During Staffing Shortages Due to COVID-19

The COVID-19 pandemic changed home infusion nursing dramatically by increasing demand for home infusion nurses while decreasing their availability. Home infusion of intravenous immunoglobulin (IVIg) is an option for treatment of numerous conditions and requires considerable infusion time. Use of a higher-concentration IVIg product and shorter escalation increments may decrease required infusion time. The authors conducted a retrospective database analysis that identified 23 patients receiving IVIg before transitioning to a 10% IVIg product with a 15-minute rate escalation protocol (Gammaplex 10% IVIg) and evaluated the total infusion time before and after the transition. Among the 23 who received IVIg, the mean ± SD IVIg dose per dosing cycle before transitioning was 1.2 ± 0.7 g/kg given in 1 to 5 infusions per cycle. The mean ± SD time per infusion was 2.8 ± 0.8 hours before the transition and 2.6 ± 0.7 hours per infusion after the transition. The infusion time decreased after transition in 13 patients (56.5%), did not change in 5 patients (21.7%), and increased in 5 patients (21.7%). Nurse education on IVIg rate escalation may facilitate faster achievement of the maximum safe infusion rate and reduce infusion times. A trial transition to this 10% IVIg product with a 15-minute rate escalation protocol may also reduce infusion times.

A Scoping Review of Barriers and Facilitators Affecting the Lives of People With Disabilities During COVID-19

Purpose

This scoping review aimed to identify the barriers and facilitators to everyday activities and social participation of people with a disability (PWD) during the first wave of the COVID-19 pandemic.

Methods

The search terms (disability and COVID-19) were used in four databases: CINAHL, Medline (Ovid), EMBASE and Web of Science. The search conducted from January 2019 to September 22, 2020, identified 465 peer reviewed articles and abstracts and were screened in Covidence software. Studies were included if they had the terms “COVID-19” and “disability,” were published in English, and specifically examined how COVID-19 impacted the daily lives of PWD. Exclusion criteria included: disability as a symptom or result of COVID-19, the health outcomes when PWD acquired COVID-19, disability leave for someone who is sick and the risk of acquiring the disease for PWD. 74 articles met the inclusion criteria and were analyzed via data charting. Charting began with existing barriers and facilitators identified by the World Health Organization and new barriers and facilitators, that emerged from the texts were added during this process.

Results

The barriers that emerged included: access to information, ease of communication, financial impacts, mental health impacts, access to essential services, physical safety, educational challenges, and changes to care and rehabilitation. Significant facilitators included: changes to care and rehabilitation, new innovations, social and familial support and inclusive policy measures.

Conclusion

COVID-19 exacerbated existing challenges in the lives of PWD and raised new quality of life concerns. Findings also demonstrate that policy makers, health care professionals and others continually support PWD in times of crisis.

Radiological profile of patients undergoing Chest X-ray and computed tomography scans during COVID-19 outbreak

BACKGROUND & OBJECTIVE

Radiology has played a significant role in the diagnosis and quantifying the severity of COVID 19 pulmonary disease. This study was conducted to assess patterns and severity of COVID-19 pulmonary disease based on radiological imaging.

METHODS

A prospective observational study was conducted in a large tertiary care public sector teaching hospital of Karachi, Pakistan from June 2020 till August 2020. All confirmed and suspected COVID-19 patients referred for chest X-rays and computed tomography (CT) scans were evaluated along with RT-PCR results. Suspected patients were followed for RT-PCR. Radiological features and severity of imaging studies were determined.

RESULTS

Of 533 patients in whom X-rays were performed, majority had severe/critical findings, i.e., 304 (57.03%). Of 97 patients in whom CT scan was performed, mild/moderate findings were observed in 63 (64.94%) patients. Of 472 patients with abnormal X-rays, majority presented with alveolar pattern 459 (97.2%), bilateral lung involvement 453 (89.6%), and consolidation 356 (75.4%). Moreover, lobar predominance showed lower zone preponderance in 446 (94.5%) patients. Of 88 patients with abnormal CT findings, ground-glass opacity (GGO) 87 (98.9%) and crazy paving 69 (78.4%) were the most common findings. An insignificantly higher association of PCR positive cases was observed with severe/critical X-rays (p-value 0.076) and CT scan findings (p-value 0.431).

CONCLUSION

Most common patterns on CT scans were GGO and crazy paving. While on chest radiographs, bilateral lung involvement with alveolar pattern and consolidation were most common findings. On X-rays, majority had severe/critical whereas CT scan had mild/moderate findings.

Inflammatory neuropsychiatric disorders and COVID-19 neuroinflammation

Neuropsychiatric sequalae to coronavirus disease 2019 (COVID-19) infection are beginning to emerge, like previous Spanish influenza and severe acute respiratory syndrome episodes. Streptococcal infection in paediatric patients causing obsessive compulsive disorder (PANDAS) is another recent example of an infection-based psychiatric disorder. Inflammation associated with neuropsychiatric disorders has been previously reported but there is no standard clinical management approach established. Part of the reason is that it is unclear what factors determine the specific neuronal vulnerability and the efficacy of anti-inflammatory treatment in neuroinflammation. The emerging COVID-19 data suggested that in the acute stage, widespread neuronal damage appears to be the result of abnormal and overactive immune responses and cytokine storm is associated with poor prognosis. It is still too early to know if there are long-term-specific neuronal or brain regional damages associated with COVID-19, resulting in distinct neuropsychiatric disorders. In several major psychiatric disorders where neuroinflammation is present, patients with abnormal inflammatory markers may also experience less than favourable response or treatment resistance when standard treatment is used alone. Evidence regarding the benefits of co-administered anti-inflammatory agents such as COX-2 inhibitor is encouraging in selected patients though may not benefit others. Disease-modifying therapies are increasingly being applied to neuropsychiatric diseases characterised by abnormal or hyperreactive immune responses. Adjunct anti-inflammatory treatment may benefit selected patients and is definitely an important component of clinical management in the presence of neuroinflammation.

Patient perceptions of outcome measures in chronic inflammatory demyelinating polyneuropathy: A study of the Inflammatory Rasch-built Overall Disability Scale

BACKGROUND

Patients' perceptions of outcome measures used in chronic inflammatory demyelinating polyneuropathy (CIDP) are unknown.

METHODS

We performed a cross-sectional evaluation of patient perceptions of the Inflammatory Rasch-built Overall Disability Scale (I-RODS) from 41 subjects with CIDP through a structured questionnaire. We assessed perceived hesitation to provide a response, item importance and relevance, understanding of specific items and factors affecting responses.

RESULTS

Hesitation to provide a categorical answer was reported by 20% of subjects or more, for 5/24 (20.8%) items. Uncertainty was most frequent for "travel by public transport" (22.4%) and "catch an object (e.g., ball)" (24%). Six of 24 (25%) items were perceived as unimportant to their disease by at least a third of participants. Items most commonly perceived as unimportant were "travel by public transport" in 53.7%, "catch an object (e.g., ball)" in 61% and "dance" in 65.9%. Several items were frequently perceived as irrelevant. These included "move a chair" (39%), "do the dishes" (46.3%), "catch an object (e.g., ball)" (61%), "travel by public transport" (68.3%) and "stand for hours" (82.9%). The understanding of multiple items such as "read a book", "sit on a toilet" and "take a shower" was found to be highly variable. Fatigue was perceived more commonly than mood (53.7% vs. 17.1%, p = 0.001), and more commonly in younger subjects (p = 0.037), as influencing responses to the I-RODS.

CONCLUSIONS

Patient-perceived uncertainty, unimportance, irrelevance and poor understanding of items, as well as fatigue and mood, impact on the value of the I-RODS. Greater emphasis on individualized disability assessments requires consideration in future.

Impact of COVID-19 pandemic in the activity of a Therapeutic Apheresis unit in Italy

INTRODUCTION

The recent Coronavirus Disease 2019 (COVID-19) outbreak has led to profound and rapid changes in the Italian and Veneto Region Healthcare System. This context also includes the quick reorganization which the Apheresis Unit (AU) of the Padova University Hospital, i.e. the Regional Reference Center for Therapeutic Apheresis (TA), had to face.

MATERIAL AND METHODS

The study retrospectively evaluated the TA activity (procedures performed, patients treated and consultations) during the COVID-19 pandemic, from March to April 2020, comparing the activity in the same time period in 2018 and 2019.

RESULTS

In the period analyzed, a significant reduction in both the total number of procedures performed and of patients treated, respectively by 17 % and 16 % for the procedures and by 19 % and 20 % for patients treated compared to the same period of 2018 and 2019, respectively, was observed. A concomitant reduction in requests for TA consultation for new patients (both outpatients and inpatients) was observed, equal to 32 % and 21 % compared to 2018 and 2019, respectively.

CONCLUSION

Many reasons determined the observed reduction in the TA activity during the recent COVID-19 outbreak. The AU itself was quickly reorganized in terms of location and supplies to allow for the appropriate COVID-19 patients care. Many non urgent cases, after multidisciplinary discussion between Clinicians and Apheresis Specialists, were deferred, maintaining close phone and e-mail contact with patients.

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.

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.

Neuropathogenesis and Neurologic Manifestations of the Coronaviruses in the Age of Coronavirus Disease 2019: A Review

Importance

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in December 2019, causing human coronavirus disease 2019 (COVID-19), which has now spread into a worldwide pandemic. The pulmonary manifestations of COVID-19 have been well described in the literature. Two similar human coronaviruses that cause Middle East respiratory syndrome (MERS-CoV) and severe acute respiratory syndrome (SARS-CoV-1) are known to cause disease in the central and peripheral nervous systems. Emerging evidence suggests COVID-19 has neurologic consequences as well.

Observations

This review serves to summarize available information regarding coronaviruses in the nervous system, identify the potential tissue targets and routes of entry of SARS-CoV-2 into the central nervous system, and describe the range of clinical neurological complications that have been reported thus far in COVID-19 and their potential pathogenesis. Viral neuroinvasion may be achieved by several routes, including transsynaptic transfer across infected neurons, entry via the olfactory nerve, infection of vascular endothelium, or leukocyte migration across the blood-brain barrier. The most common neurologic complaints in COVID-19 are anosmia, ageusia, and headache, but other diseases, such as stroke, impairment of consciousness, seizure, and encephalopathy, have also been reported.

Conclusions and Relevance

Recognition and understanding of the range of neurological disorders associated with COVID-19 may lead to improved clinical outcomes and better treatment algorithms. Further neuropathological studies will be crucial to understanding the pathogenesis of the disease in the central nervous system, and longitudinal neurologic and cognitive assessment of individuals after recovery from COVID-19 will be crucial to understand the natural history of COVID-19 in the central nervous system and monitor for any long-term neurologic sequelae.

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.

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.

In this Review, the authors synthesize recommendations on the management of neuroimmunological disease in the context of the COVID-19 pandemic. They consider these recommendations alongside the first available data from patients, and provide an overview of management approaches in the COVID-19 era.

The risk that the coronavirus disease 2019 (COVID-19) pandemic poses for people who are receiving immunotherapy for neuroimmunological disease remains unclear.

Guidelines and statements have been published by societies and individuals, but the level of consensus differs for different aspects; we use a Delphi-like process to clarify where consensus exists.

Without evidence, management of neuroimmunological diseases in the context of COVID-19 requires application of the first principles of immunotherapy, taking into account disease-related, patient-related, physician-related, environment-related and COVID-19-related factors.

In general, corticosteroids, intravenous immunoglobulin and/or plasma exchange for the treatment of acute neuroimmunological deteriorations can be administered with low risk in the COVID-19 pandemic.

In general, ongoing immunotherapy should not be stopped because of the COVID-19 pandemic; treatment initiation and optimization are also recommended.

For some aspects of immunotherapy in the context of COVID-19, consensus in the literature is low, and collection of data in patient registries is important for resolving these uncertainties.

Amyotrophic lateral sclerosis care and research in the United States during the COVID-19 pandemic: Challenges and opportunities

Coronavirus disease 2019 has created unprecedented challenges for amyotrophic lateral sclerosis (ALS) clinical care and research in the United States. Traditional evaluations for making an ALS diagnosis, measuring progression, and planning interventions rely on in‐person visits that may now be unsafe or impossible. Evidence‐ and experience‐based treatment options, such as multidisciplinary team care, feeding tubes, wheelchairs, home health, and hospice, have become more difficult to obtain and in some places are unavailable. In addition, the pandemic has impacted ALS clinical trials by impairing the ability to obtain measurements for trial eligibility, to monitor safety and efficacy outcomes, and to dispense study drug, as these also often rely on in‐person visits. We review opportunities for overcoming some of these challenges through telemedicine and novel measurements. These can reoptimize ALS care and research in the current setting and during future events that may limit travel and face‐to‐face interactions.

Management challenges for chronic dysimmune neuropathies during the COVID-19 pandemic

Since March 2020, the COVID-19 pandemic has led to the need to re-think the delivery of services to patients with chronic dysimmune neuropathies. Telephone/video consultations have become widespread but have compounded concerns about objective evaluation. Therapeutic decisions need, more than ever before, to be considered in the best interests of both patients, and society, while not denying function-preserving/restoring treatment. Immunoglobulin therapy and plasma exchange, for those treated outside of the home, expose patients to the hazards of hospital or outpatient infusion centers. Steroid therapy initiation and continuation pose increased infectious risk. Immunosuppressant therapy similarly becomes highly problematic, with the risks of treatment continuation enhanced by uncertainties regarding duration of the pandemic. The required processes necessitate considerable time and effort especially as resources and staff are re-deployed to face the pandemic, but are essential for protecting this group of patients and as an integral part of wider public health actions.
