Bulbar Onset Amyotrophic Lateral Sclerosis in a COVID-19 Patient: A Case Report.

Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disorder with a largely unknown etiology. In this case, we are presenting an 84-year-old male patient who was admitted for acute hypoxemic respiratory failure secondary to coronavirus disease 2019 (COVID-19) infection. He was neurologically intact. His infection improved and oxygen requirement was gradually weaned off allowing for discharge. However, he was admitted again a month later with progressive dysphagia and aspiration that were confirmed on videofluoroscopic study. He was also found to have mild dysarthria, bulbar muscle weakness, bilateral lower motor neuron facial nerve palsy, diffuse hyporeflexia on four extremities with intact sensory function. Diagnosis of ALS was suspected after extensive workup was pursued and ruled out nutritional, structural, autoimmune, infectious and inflammatory disorders. This case is only the third reported case in medical literature to suggest COVID-19 infection as a triggering/accelerating factor of ALS progression.

Experience with telemedicine in neuromuscular clinic during COVID-19 pandemic.

Objectives: The aim of the present study was to evaluate the feasibility and acceptability of telehealth for the care of neuromuscular patients during the COVID-19 pandemic. Methods: Neuromuscular patients or their caregivers, as well as health care providers (HCPs), who completed a televisit during the pandemic received an online survey, assessing satisfaction with the visit, quality of care, and experience with the televisit interference. Results: Surveys from 46 neuromuscular patients (including 18 with motor neuron disease [MND])/caregivers and 7 HCPs were completed. Several aspects of televisits including good communication, adequate time to discuss concern, provision of equal care, and telemedicine interference were rated favorably among participants. Telehealth was strongly satisfactory in 30 (65.22%) and satisfactory in 15 (32.61%) neuromuscular patients/caregivers. In 18 MND patients, this was 10 (55.56%) and 7 (38.89%), respectively. Moreover, 24 (52.17%) neuromuscular patients/caregivers would strongly agree and 18 (39.13%) would agree to participate again in televisits. This was 10 (55.56%) and 4 (33.33%) for MND cases, respectively. Various medical issues were addressed during the televisits including medication management, ordering tests/referrals, discussion of goals of care, and research. The predictive stepwise logistic model found younger age as a predicting factor for higher satisfaction from, or participation again in, televisits in neuromuscular patients. Limb onset location was also a predicting factor for strong satisfaction from televisits in MND cases. Conclusions: Telemedicine is feasible and highly effective at achieving personalized care that was rated satisfactory by the majority of neuromuscular patients/caregivers and HCPs during the COVID-19 pandemic.

Ultrasound-guided glenohumeral joint injections for shoulder pain in ALS: A case series.

Introduction: Shoulder pain is a common secondary impairment for people living with ALS (PALS). Decreased range of motion (ROM) from weakness can lead to shoulder pathology, which can result in debilitating pain. Shoulder pain may limit PALS from participating in activities of daily living and may have a negative impact on their quality of life. This case series explores the efficacy of glenohumeral joint injections for the management of shoulder pain due to adhesive capsulitis in PALS. Methods: People living with ALS and shoulder pain were referred to sports medicine-certified physiatrists for diagnostic evaluation and management. They completed the Revised ALS Functional Rating Scale and a questionnaire asking about their pain levels and how it impacts sleep, function, and quality of life at baseline pre-injection, 1-week post-injection, 1 month post-injection, and 3 months post-injection. Results: We present five cases of PALS who were diagnosed with adhesive capsulitis and underwent glenohumeral joint injections. Though only one PALS reported complete symptom resolution, all had at least partial symptomatic improvement during the observation period. No complications were observed. Conclusions: People living with ALS require a comprehensive plan to manage shoulder pain. Glenohumeral joint injections are safe and effective for adhesive capsulitis in PALS, but alone may not completely resolve shoulder pain. Additional therapies to improve ROM and reduce pain should be considered.

Saliva and Saliva Extracellular Vesicles for Biomarker Candidate Identification-Assay Development and Pilot Study in Amyotrophic Lateral Sclerosis.

Saliva is gaining increasing attention as a source of biomarkers due to non-invasive and undemanding collection access. Extracellular vesicles (EVs) are nano-sized, cell-released particles that contain molecular information about their parent cells. In this study, we developed methods for saliva biomarker candidate identification using EV-isolation and proteomic evaluation. We used pooled saliva samples for assay development. EVs were isolated using membrane affinity-based methods followed by their characterization using nanoparticle tracking analysis and transmission electron microscopy. Subsequently, both saliva and saliva-EVs were successfully analyzed using proximity extension assay and label-free quantitative proteomics. Saliva-EVs had a higher purity than plasma-EVs, based on the expression of EV-proteins and albumin. The developed methods could be used for the analysis of individual saliva samples from amyotrophic lateral sclerosis (ALS) patients and controls (n = 10 each). The starting volume ranged from 2.1 to 4.9 mL and the amount of total isolated EV-proteins ranged from 5.1 to 42.6 µg. Although no proteins were significantly differentially expressed between the two groups, there was a trend for a downregulation of ZNF428 in ALS-saliva-EVs and an upregulation of IGLL1 in ALS saliva. In conclusion, we have developed a robust workflow for saliva and saliva-EV analysis and demonstrated its technical feasibility for biomarker discovery.

Impact of the covid-19 pandemic on amyotrophic lateral sclerosis care in the UK.

The Covid-19 pandemic has impacted healthcare. Our aim was to identify how amyotrophic lateral sclerosis (ALS) care in the UK has been affected by the pandemic by exploring the experiences of people living with ALS (plwALS), healthcare professionals (HCPs) working with plwALS, and ALS care centers. Three surveys were carried out to explore the experiences of plwALS, HCPs and ALS care centers during the pandemic. Quantitative data were analyzed using descriptive and inferential statistics and triangulated with the qualitative data which were analyzed thematically. Responses from 53 plwALS, 73 HCPs and 23 ALS care centers were analyzed. Five main themes were identified: keeping safe, losses, negative emotions, delivering care and alternative care delivery in a pandemic. PlwALS and HCPs felt that care was sub-optimal as a result of the pandemic. Changes to care included longer waiting times and face-to-face appointments being canceled or replaced by virtual consultations. While benefits of virtual consultations were reported, concerns were raised about incomplete clinical assessments and the disruption of provision of testing and interventions. ALS care has changed as a result of the pandemic. Patients have had a lack of face-to-face contact with HCPs and have experienced delays to investigations and treatments. PlwALS and HCPs were concerned about the impact of this change, but the long-term implications remain unclear. We propose recommendations for HCPs caring for plwALS, that will promote continuity of evidenced based care in the context of a pandemic.

Virus exposure and neurodegenerative disease risk across national biobanks.

With recent findings connecting the Epstein-Barr virus to an increased risk of multiple sclerosis and growing concerns regarding the neurological impact of the coronavirus pandemic, we examined potential links between viral exposures and neurodegenerative disease risk. Using time series data from FinnGen for discovery and cross-sectional data from the UK Biobank for replication, we identified 45 viral exposures significantly associated with increased risk of neurodegenerative disease and replicated 22 of these associations. The largest effect association was between viral encephalitis exposure and Alzheimer's disease. Influenza with pneumonia was significantly associated with five of the six neurodegenerative diseases studied. We also replicated the Epstein-Barr/multiple sclerosis association. Some of these exposures were associated with an increased risk of neurodegeneration up to 15 years after infection. As vaccines are currently available for some of the associated viruses, vaccination may be a way to reduce some risk of neurodegenerative disease.

Psychological Support for Family Caregivers of Patients With Amyotrophic Lateral Sclerosis at the Time of the Coronavirus Disease 2019 Pandemic: A Pilot Study Using a Telemedicine Approach.

The coronavirus disease 2019 (COVID-19) pandemic confined most of the population to homes worldwide, and then, a lot of amyotrophic lateral sclerosis (ALS) centers moved to telemedicine services to continue to assist both patients with ALS and their caregivers. This pilot, randomized, controlled study aimed to explore the potential role of psychological support interventions for family caregivers of patients with ALS through resilience-oriented sessions of group therapy during the COVID-19 pandemic. In total, 12 caregivers agreed to be remotely monitored by our center since March 2020 and underwent scales for global burden (i.e., Caregiver Burden Inventory, CBI), resilience (i.e., Connor Davidson Resilience Scale, CD-RISC), and perceived stress (i.e., Perceived Stress Scale, PSS) at two-time points (i.e., at pre-treatment assessment and after 9 months or at post-treatment assessment). They were randomized into two groups: the former group underwent resilience-oriented sessions of group therapy two times a month for 3 months, while the latter one was only remotely monitored. No significant differences were found in CBI, CD-RISC, and PSS during the 9-month observation period in the treated group compared with the control group, suggesting a trend toward stability of caregiver burden together with resilience and perceived stress scores in all the subjects monitored. The lack of differences in caregivers' burden, resilience, and perceived stress scores by comparing the two groups monitored during 9 months could be due to the co-occurrence of the COVID-19 pandemic with the stressful events related to caring for patients with ALS that might have hindered the detection of significant benefits from short-lasting psychological support.
