Doctor-Should I get the COVID-19 vaccine? Infection and immunization in individuals with neuromuscular disorders.

The clinical course of neuromuscular disorders (NMDs) can be affected by infections, both in immunocompetent individuals, and in those with reduced immunocompetence due to immunosuppressive/immunomodulating therapies. Infections and immunizations may also trigger NMDs. There is a potential for reduced efficacy of immunizations in patients with reduced immunocompetence. The recent vaccination program for coronavirus disease-2019 (COVID-19) raises several questions regarding the safety and efficacy of this vaccine in individuals with NMDs. In this Practice Topic article, we address the role of vaccine-preventable infections in NMDs and the safety and efficacy of immunization in individuals with NMDs, with emphasis on vaccination against COVID-19.

COVID-19-associated Guillain-Barré syndrome: The early pandemic experience.

Guillain-Barré syndrome (GBS) is an inflammatory polyradiculoneuropathy associated with numerous viral infections. Recently, there have been many case reports describing the association between coronavirus disease-2019 (COVID-19) and GBS, but much remains unknown about the strength of the association and the features of GBS in this setting. We reviewed 37 published cases of GBS associated with COVID-19 to summarize this information for clinicians and to determine whether a specific clinical or electrodiagnostic (EDx) pattern is emerging. The mean age (59 years), gender (65% male), and COVID-19 features appeared to reflect those of hospitalized COVID-19 patients early in the pandemic. The mean time from COVID-19 symptoms to GBS symptoms was 11 days. The clinical presentation and severity of these GBS cases was similar to those with non-COVID-19 GBS. The EDx pattern was considered demyelinating in approximately half of the cases. Cerebrospinal fluid, when assessed, demonstrated albuminocytologic dissociation in 76% of patients and was negative for severe acute respiratory distress syndrome-coronavirus-2 (SARS-CoV-2) in all cases. Serum antiganglioside antibodies were absent in 15 of 17 patients tested. Most patients were treated with a single course of intravenous immunoglobulin, and improvement was noted within 8 weeks in most cases. GBS-associated COVID-19 appears to be an uncommon condition with similar clinical and EDx patterns to GBS before the pandemic. Future studies should compare patients with COVID-19-associated GBS to those with contemporaneous non-COVID-19 GBS and determine whether the incidence of GBS is elevated in those with COVID-19.

Guidance for resumption of routine electrodiagnostic testing during the COVID-19 pandemic.

As the world accommodates to the coronavirus disease 2019 (COVID-19) pandemic, routine in-person medical services are resuming. The resumption of non urgent electrodiagnostic (EDX) testing faces unique challenges due to the long duration of the procedure and direct close contact with patients, including studies with risk of exposure to oropharyngeal secretions. We provide consensus guidance for resumption of EDX testing, addressing scheduling, patient arrival and registration, use of personal protective equipment, COVID-19 screening and testing, the performance of EDX testing in outpatient and inpatient settings, cleaning and maintenance of the EDX equipment and laboratory, balancing trainee safety and training requirements, and patient care issues. These are broad recommendations that need to be adapted to local COVID-19 risks, institutional guidelines and policies, and changing federal, state, and local regulations, and to changes in the pandemic over time.

Practical guidance for managing electromyography requests and testing during the COVID-19 pandemic.

The COVID-19 pandemic has necessitated cancelation of elective or nonurgent contact with the healthcare system, including nonurgent nerve conduction studies and electromyography (electrodiagnostic [EDX] studies). The definitions of elective and nonurgent are physician judgments, and often are not straightforward. Clinical care must be provided to help our patients in a timely manner, while keeping them, healthcare personnel, and the community safe. Benefit/risk stratification is an important part of this process. We have stratified EDX studies into three categories: Urgent, Non-urgent, and Possibly Urgent, in an effort to help clinicians triage these referrals. For each category, we provide a rationale and some examples. However, each referral must be reviewed on a case-by-case basis, and the clinical situation will evolve over time, necessitating flexibility in managing EDX triaging. Engaging the referring clinician and, at times, the patient, may be useful in the triage process.
