Disparities in Telehealth Care in Multiple Sclerosis.

Background and Objectives: The COVID-19 pandemic has dramatically increased telehealth use. We assessed access to and use of telehealth care, including videoconferencing and usability of videoconferencing, among persons with multiple sclerosis (MS). Methods: In Fall 2020, we surveyed participants in the North American Research Committee on Multiple Sclerosis Registry. Participants reported availability and receipt of MS care or education through telehealth. Participants who completed ≥1 live videoconferencing visit completed the Telehealth Usability Questionnaire (TUQ). We tested factors associated with access to and receipt of telehealth care using logistic regression. We tested factors associated with TUQ scores using quantile regression. Results: Of the 8,434 participants to whom the survey was distributed, 6,043 responded (71.6%); 5,403 were eligible for analysis. Of the respondents, 4,337 (80.6%) were women, and they had a mean (SD) age of 63.2 (10.0) years. Overall, 2,889 (53.5%) reported access to MS care via telehealth, and 2,110 (39.1%) reported receipt of MS care via telehealth including 1,523 (28%) via videoconference. Among participants who reported telehealth was available, older age was associated with decreased odds of having a telehealth video visit; higher income and being physically active were associated with increased odds. Older age and moderate to very severe visual symptoms were associated with lower perceived usability of telehealth. Discussion: Older age, lower socioeconomic status, and disease-related impairments are associated with less access to and use of telehealth services in people with MS. Barriers to telehealth should be addressed to avoid aggravating health care disparities when using digital medicine.

COVID-19 in the pregnant or postpartum MS patient: Symptoms and outcomes.

Women with multiple sclerosis (MS) are often of childbearing age. Thirty-six women with MS who were pregnant (n = 27) or within 6 weeks postpartum (n = 9) were reported in the North American COViMS registry and their COVID-19 outcomes were described. One pregnant and one postpartum woman were hospitalized. No deaths occurred. To compare COVID-19 clinical outcomes in pregnant and postpartum females with females who were not pregnant or postpartum, a 1:2 propensity score match was performed. While not powered to detect small differences, it was reassuring that no increased risks for those with MS who were pregnant/postpartum were revealed.

Impact of the COVID-19 pandemic on patients with myasthenia gravis: A survey of the Myasthenia Gravis Foundation of America MG patient registry.

INTRODUCTION/AIMS: Factors associated with coronavirus disease 2019 (COVID-19) infection among the myasthenia gravis (MG) population are incompletely understood. This study aimed to characterize the behavior of MG patients during the pandemic and to examine risk factors associated with COVID-19 infection. METHODS: A "COVID-19 Survey" was sent to MG Patient Registry participants in the summer of 2020 (CSS20) and winter of 2021 (CWS21). Survey results were summarized descriptively. Demographics, disease characteristics, medication use, and survey results were compared between those reporting COVID-19 diagnosis (COVID), COVID-19 like symptoms without diagnosis (COVID-Like), and asymptomatic participants. RESULTS: A total of 454 and 665 participants completed the CSS20 and CWS21 surveys respectively; 326 participants completed both. Most continued follow-up visits and MG treatments. The frequency of COVID-like symptoms was similar between CSS20 and CWS21, while COVID-19 exposure (6% vs. 27%), COVID-19 testing among symptomatic individuals (35% vs. 78%), and COVID-19 diagnosis (0.2% vs. 6%) were higher in the CWS21. Cough, fever, fatigue, myalgia, anosmia/ageusia, and hospital and intensive care unit (ICU) admissions were more frequent in the COVID compared to the COVID-Like group. COVID-19 exposure (odds ratio [OR] 7.88), number of people in the household (OR 1.31), and report of MG exacerbation before the pandemic (OR 2.6) were independently associated with COVID-19 infection. DISCUSSION: COVID-19 affected MG patients increasingly through the early pandemic. While face-to-face contact with a COVID-19 infected individual was an obvious risk factor, MG patients who had more people in the household and unstable disease were at elevated risk for COVID-19 infection.

The late onset of emotional distress in people with progressive multiple sclerosis during the Covid-19 pandemic: longitudinal findings from the CogEx study.

OBJECTIVE: An earlier follow-up study from the CogEx rehabilitation trial showed little change in symptoms of depression, anxiety and psychological distress during the first COVID-19 lockdown compared to pre-pandemic measurements. Here, we provide a second follow-up set of behavioral data on the CogEx sample. METHODS: This was an ancillary, longitudinal follow-up study in CogEx, a randomized controlled trial of exercise and cognitive rehabilitation in people with progressive MS involving 11 centres in North America and Europe. Only individuals impaired on the Symbol Digit Modalities Test (SDMT) were included. Participants repeated the COVID Impact survey administered approximately a year later and completed self-report measures of depression, anxiety and MS symptoms that had been obtained at the trial baseline and during the first COVID Impact survey. Participants who completed the second COVID Impact follow-up were included. To identify predictors of the participants' ratings of their mental and physical well-being, step-wise linear regression was conducted. RESULTS: Of the 131 participants who completed the first COVID impact survey, 74 participants completed the second follow-up survey (mean age 52 (SD = 6.4) years, 62.2% female, mean disease duration 16.4 (SD = 9.0) years, median EDSS 6.0). Pandemic restrictions prevented data collection from sites in Denmark and England (n = 57). The average time between measurements was 11.4 (SD = 5.56) months. There were no significant differences in age, sex, EDSS, disease course and duration between those who participated in the current follow-up study (n = 74) and the group that could not (n = 57). One participant had COVID in the time between assessments. Participants now took a more negative view of their mental/psychological well-being (p = 0.0001), physical well-being (p = 0.0009) and disease course (p = 0.005) compared to their last assessment. Depression scores increased on the HADS-depression scale (p = 0.01) and now exceeded the clinically significant threshold of ≥ 8.0 for the first time. Anxiety scores on the HADS remained unchanged. Poorer mental well-being was predicted by HADS depression scores (p = 0.012) and a secondary-progressive disease course (p = 0.0004). CONCLUSIONS: A longer follow-up period revealed the later onset of clinically significant depressive symptoms on the HADS and a decline in self-perceptions of mental and physical well-being associated with the COVID-19 pandemic relative to the first follow-up data point. TRIAL REGISTRATION: The trial was registered on September 20th 2018 at www. CLINICALTRIALS: gov having identifier NCT03679468. Registration was performed before recruitment was initiated.

NOVA primary results randomised controlled study of natalizumab Q6W versus continued Q4W treatment for MS

BackgroundNatalizumab every-6-week (Q6W) dosing is associated with lower progressive multifocal leukoencephalopathy risk than every-4-week dosing (Q4W) in retrospective analyses. NOVA is the first randomised trial to assess Q6W efficacy.ObjectiveEvaluate natalizumab Q6W efficacy in patients previously treated with natalizumab Q4W for≥12 months compared with continuation of Q4W over 72 weeks.MethodsNOVA is a randomised, controlled, open-label, rater-blinded phase 3b trial. Included patients were treated with natalizumab Q4W without relapse for ≥12 months. Patients were randomised 1:1 to Q4W (n=248) or Q6W (n=251). The primary endpoint was new/newly enlarging T2 (N/NET2) lesions. Secondary endpoints included clinical and safety outcomes.ResultsProportions of patients with N/NET2 lesions were low in both arms (Q4W:4.1%;Q6W:4.3%). Differ- ences in mean N/NET2 lesions for Q4W and Q6W (primary estimand: 0.05 vs 0.20 [P=0.0755];secondary estimand: 0.06 vs 0.31 [P=0.0437]) were driven by two Q6W patients with extreme (≥25) values. Secondary outcomes were similar for Q4W and Q6W.ConclusionsOverall, NOVA data suggest most patients stable on natalizumab Q4W can switch to Q6W without clinically meaningful loss of efficacy.

Satisfaction with modes of telemedicine delivery during COVID-19: A randomized, single-blind, parallel group, noninferiority trial.

BACKGROUND: Little is known about satisfaction with different modes of telemedicine delivery. The objective of this study was to determine whether patient satisfaction with phone-only was noninferior to video visits. METHODS: We conducted a parallel group, randomized (1:1), single-blind, noninferiority trial in multispecialty clinics at a tertiary academic medical center. Adults age ≥ 60 years or with Medicare/Medicaid insurance were eligible. Primary outcome was visit satisfaction rate (9 or 10 on a 0-10 satisfaction scale). Noninferiority was determined if satisfaction with phone-only (intervention) versus video visits (comparator) was no worse by a -15% prespecified noninferiority margin. We performed modified intent-to-treat (mITT) and per protocol analyses, after adjusting for age and insurance. RESULTS: 200 participants, 43% Black, 68% women completed surveys. Visit satisfaction rates were high. In the mITT analysis, phone-only visits were noninferior by an adjusted difference of 3.2% (95% CI, -7.6% to 14%). In the per protocol analysis, phone-only were noninferior by an adjusted difference of -4.1% (95% CI, -14.8% to 6.6%). The proportion of participants who indicated they preferred the same type of telemedicine visit as their next clinic visit were similar (30.2% vs 27.9% video vs phone-only, p = 0.78) and a majority said their medical concerns were addressed and would recommend a telemedicine visit. CONCLUSIONS: Among a group of diverse, established older or underserved patients, the satisfaction rate for phone-only was noninferior to video visits. These findings could impact practice and policies governing telemedicine.

Absolute quantification of plasma mitochondrial DNA by droplet digital PCR marks COVID-19 severity over time during intensive care unit admissions.

Increased plasma mitochondrial DNA concentrations are associated with poor outcomes in multiple critical illnesses, including COVID-19. However, current methods of cell-free mitochondrial DNA quantification in plasma are time-consuming and lack reproducibility. Here, we used next-generation sequencing to characterize the size and genome location of circulating mitochondrial DNA in critically ill subjects with COVID-19 to develop a facile and optimal method of quantification by droplet digital PCR. Sequencing revealed a large percentage of small mitochondrial DNA fragments in plasma with wide variability in coverage by genome location. We identified probes for the mitochondrial DNA genes, cytochrome B and NADH dehydrogenase 1, in regions of relatively high coverage that target small sequences potentially missed by other methods. Serial assessments of absolute mitochondrial DNA concentrations were then determined in plasma from 20 critically ill subjects with COVID-19 without a DNA isolation step. Mitochondrial DNA concentrations on the day of enrollment were increased significantly in patients with moderate or severe acute respiratory distress syndrome (ARDS) compared with those with no or mild ARDS. Comparisons of mitochondrial DNA concentrations over time between patients with no/mild ARDS who survived, patients with moderate/severe ARDS who survived, and nonsurvivors showed the highest concentrations in patients with more severe disease. Absolute mitochondrial DNA quantification by droplet digital PCR is time-efficient and reproducible; thus, we provide a valuable tool and rationale for future studies evaluating mitochondrial DNA as a real-time biomarker to guide clinical decision-making in critically ill subjects with COVID-19.

Attitudes toward coronavirus disease 2019 vaccination in people with multiple sclerosis.

Objective: We estimated coronavirus disease 2019 (COVID-19) vaccination rates in the North American Research Committee on Multiple Sclerosis (NARCOMS) population and investigated reasons for vaccine hesitancy. Methods: In Spring 2021, we surveyed the NARCOMS participants about COVID-19 vaccinations. Participants reported whether they had received any COVID-19 vaccination; if not, they reported why not. They also reported whether they had received influenza vaccination. Using multivariable logistic regression, we assessed participant characteristics associated with uptake of COVID-19 and influenza vaccines. Results: Of 4955 eligible respondents, 3998 (80.7%) were females with a mean (SD) age of 64.0 (9.7) years. Overall, 4165 (84.1%) reported that they had received a COVID-19 vaccine, most often Pfizer-BioNTech and Moderna, and 3723 (75.4%) received a seasonal influenza vaccine. Reasons for not getting the COVID-19 vaccine included possible adverse effects (47.73%), possible lack of efficacy (13.7%), and lack of perceived need (17.1%). Factors associated with receiving the COVID-19 vaccine included receipt of influenza vaccine, older age, higher socioeconomic status, any leisure physical activity, and use of disease-modifying therapy. Conclusion: In this older cohort of people with multiple sclerosis, COVID-19 vaccine uptake was high, exceeding uptake of seasonal influenza vaccine. Concerns regarding safety, efficacy, and lack of perceived risk were associated with not obtaining the COVID-19 vaccine.

Risk of COVID-19 infection and severe disease in MS patients on different disease-modifying therapies.

BACKGROUND: The risk of SARS-CoV-2 infection and severity with disease modifying therapies (DMTs) in multiple sclerosis (MS) remains unclear, with some studies demonstrating increased risks of infection with B-cell-depleting (anti-CD20) therapies and severity, while others fail to observe an association. Most existing studies are limited by a reliance on 'numerator' data (i.e., COVID-19 cases) only. OBJECTIVE: To assess the risks of COVID-19 by DMT, this study aimed to assess both 'numerator' (patients with SARS-CoV-2 infection) and 'denominator' data (all patients treated with DMTs of interest) to determine if any DMTs impart an increased risk of SARS-CoV-2 infection or disease severity. METHODS: We systematically reviewed charts and queried patients during clinic encounters in the NYU MS Comprehensive Care Center (MSCCC) for evidence of COVID-19 in all patients who were on the most commonly used DMTs in our clinic (sphingosine-1-phosphate receptor (S1P) modulators (fingolimod/siponimod), rituximab, ocrelizumab, fumarates (dimethyl fumarate/diroximel fumarate), and natalizumab). COVID-19 status was determined by clinical symptoms (CDC case definition) and laboratory testing where available (SARS-CoV-2 PCR, SARS-CoV-2 IgG). Multivariable analyses were conducted to determine predictors of infection and severe disease (hospitalization or death) using SARS-CoV-2 infected individuals per DMT group and all individuals on a given DMT as denominator. RESULTS: We identified 1,439 MS patients on DMTs of interest, of which 230 had lab-confirmed (n = 173; 75.2%) or suspected (n = 57; 24.8%) COVID-19. Infection was most frequent in those on rituximab (35/138; 25.4%), followed by fumarates (39/217; 18.0%), S1P modulators (43/250; 17.2%), natalizumab (36/245; 14.7%), and ocrelizumab (77/589; 13.1%). There were 14 hospitalizations and 2 deaths. No DMT was found to be significantly associated with increased risk of SARS-CoV-2 infection. Rituximab was a predictor of severe SARS-CoV-2 infection among patients with SARS-CoV-2 infection (OR 6.7; 95% CI 1.1-41.7) but did not reach statistical significance when the entire patient population on DMT was used (OR 2.8; 95% CI 0.6-12.2). No other DMT was associated with an increased risk of severe COVID-19. CONCLUSIONS: Analysis of COVID-19 risk among all patients on the commonly used DMTs did not demonstrate increased risk of infection with any DMT. Rituximab was associated with increased risk for severe disease.

SARS-CoV-2 infection increases risk of acute kidney injury in a bimodal age distribution.

BACKGROUND: Hospitalized patients with SARS-CoV2 develop acute kidney injury (AKI) frequently, yet gaps remain in understanding why adults seem to have higher rates compared to children. Our objectives were to evaluate the epidemiology of SARS-CoV2-related AKI across the age spectrum and determine if known risk factors such as illness severity contribute to its pattern. METHODS: Secondary analysis of ongoing prospective international cohort registry. AKI was defined by KDIGO-creatinine only criteria. Log-linear, logistic and generalized estimating equations assessed odds ratios (OR), risk differences (RD), and 95% confidence intervals (CIs) for AKI and mortality adjusting for sex, pre-existing comorbidities, race/ethnicity, illness severity, and clustering within centers. Sensitivity analyses assessed different baseline creatinine estimators. RESULTS: Overall, among 6874 hospitalized patients, 39.6% (n = 2719) developed AKI. There was a bimodal distribution of AKI by age with peaks in older age (≥60 years) and middle childhood (5-15 years), which persisted despite controlling for illness severity, pre-existing comorbidities, or different baseline creatinine estimators. For example, the adjusted OR of developing AKI among hospitalized patients with SARS-CoV2 was 2.74 (95% CI 1.66-4.56) for 10-15-year-olds compared to 30-35-year-olds and similarly was 2.31 (95% CI 1.71-3.12) for 70-75-year-olds, while adjusted OR dropped to 1.39 (95% CI 0.97-2.00) for 40-45-year-olds compared to 30-35-year-olds. CONCLUSIONS: SARS-CoV2-related AKI is common with a bimodal age distribution that is not fully explained by known risk factors or confounders. As the pandemic turns to disproportionately impacting younger individuals, this deserves further investigation as the presence of AKI and SARS-CoV2 infection increases hospital mortality risk.

The impact of the COVID-19 pandemic on an international rehabilitation study in MS: the CogEx experience.

Pandemic restrictions have led to changes in therapy plans and disrupted rehabilitation services for people with multiple sclerosis. CogEx is an international, multicentre MS dual-intervention (cognitive rehabilitation, aerobic exercise) randomized, controlled rehabilitation trial confined to people with progressive disease. The primary outcome is cognition (processing speed).There are 11 treatment sites in six countries with participants required to make 27 site visits over 12 weeks. Collectively, the large, in-person demands of the trial, and the varying international policies for the containment of COVID-19, might disproportionately impact the administration of CogEx. During the first lockdown, all centres closed on average for 82.9 (SD = 24.3) days. One site was required to lockdown on two further occasions. One site remained closed for 16 months. Ten staff (19.2%) were required to quarantine and eight staff (15.4%) tested positive for COVID. 10 of 264 (3.8%) participants acquired COVID-19. All survived. The mean duration of enrollment delay has been [236.7 (SD = 214.5) days]. Restarting participants whose interventions were interrupted by the pandemic meant recalculating the intervention prescriptions for these individuals. While the impact of the pandemic on CogEx has been considerable, all study sites are again open. Participants and staff have shown considerable flexibility and resilience in keeping a complex, international endeavour running. The future in general remains uncertain in the midst of a pandemic, but there is cautious optimism the study will be completed with sufficient sample size to robustly evaluate our hypothesis and provide meaningful results to the MS community on the impact of these interventions on people with progressive MS.Trial registration: The trial was registered on September 20th 2018 at www.clinicaltrials.gov having identifier NCT03679468. Registration was performed before recruitment was initiated.

COVID-19 in Patients With Neuromyelitis Optica Spectrum Disorders and Myelin Oligodendrocyte Glycoprotein Antibody Disease in North America: From the COViMS Registry.

BACKGROUND AND OBJECTIVE: To describe the impact of coronavirus disease 2019 (COVID-19) on people with neuromyelitis optica spectrum disorders (NMOSD) and myelin oligodendrocyte glycoprotein antibody disease (MOGAD). METHODS: The COVID-19 Infections in Multiple Sclerosis (MS) and Related Diseases (COViMS) Registry collected data on North American patients with MS and related diseases with laboratory-positive or highly suspected SARS-CoV-2 infection. Deidentified data were entered into a web-based registry by health care providers. Data were analyzed using t-tests, Pearson χ2 tests, or Fisher exact tests for categorical variables. Univariate logistic regression models examined effects of risk factors and COVID-19 clinical severity. RESULTS: As of June 7, 2021, 77 patients with NMOSD and 20 patients with MOGAD were reported in the COViMS Registry. Most patients with NMOSD were laboratory positive for SARS-CoV-2 and taking rituximab at the time of COVID-19 diagnosis. Most patients with NMOSD were not hospitalized (64.9% [95% CI: 53.2%-75.5%]), whereas 15.6% (95% CI: 8.3%-25.6%) were hospitalized only, 9.1% (95% CI: 3.7%-17.8%) were admitted to the ICU and/or ventilated, and 10.4% (95% CI: 4.6%-19.5%) died. In patients with NMOSD, having a comorbidity was the sole factor identified for poorer COVID-19 outcome (OR = 6.0, 95% CI: 1.79-19.98). Most patients with MOGAD were laboratory positive for SARS-CoV-2, and almost half were taking rituximab. Among patients with MOGAD, 75.0% were not hospitalized, and no deaths were recorded; no factors were different between those not hospitalized and those hospitalized, admitted to the ICU, or ventilated. DISCUSSION: Among the reported patients with NMOSD, a high mortality rate was observed, and the presence of comorbid conditions was associated with worse COVID-19 outcome. There were no deaths reported in the patients with MOGAD, although these observations are limited due to small sample size.

Telemedicine visits in myasthenia gravis: Expert guidance and the Myasthenia Gravis Core Exam (MG-CE).

INTRODUCTION/AIMS: Telemedicine may be particularly well-suited for myasthenia gravis (MG) due to the disorder's need for specialized care, its hallmark fluctuating muscle weakness, and the potential for increased risk of virus exposure among patients with MG during the coronavirus disease 2019 (COVID-19) pandemic during in-person clinical visits. A disease-specific telemedicine physical examination to reflect myasthenic weakness does not currently exist. METHODS: This paper outlines step-by-step guidance on the fundamentals of a telemedicine assessment for MG. The Myasthenia Gravis Core Exam (MG-CE) is introduced as a MG-specific, telemedicine, physical examination, which contains eight components (ptosis, diplopia, facial strength, bulbar strength, dysarthria, single breath count, arm strength, and sit to stand) and takes approximately 10 minutes to complete. RESULTS: Pre-visit preparation, remote ascertainment of patient-reported outcome scales and visit documentation are also addressed. DISCUSSION: Additional knowledge gaps in telemedicine specific to MG care are identified for future investigation.

Outcomes and Risk Factors Associated With SARS-CoV-2 Infection in a North American Registry of Patients With Multiple Sclerosis.

Importance: Emergence of SARS-CoV-2 causing COVID-19 prompted the need to gather information on clinical outcomes and risk factors associated with morbidity and mortality in patients with multiple sclerosis (MS) and concomitant SARS-CoV-2 infections. Objective: To examine outcomes and risk factors associated with COVID-19 clinical severity in a large, diverse cohort of North American patients with MS. Design, Setting, and Participants: This analysis used deidentified, cross-sectional data on patients with MS and SARS-CoV-2 infection reported by health care professionals in North American academic and community practices between April 1, 2020, and December 12, 2020, in the COVID-19 Infections in MS Registry. Health care professionals were asked to report patients after a minimum of 7 days from initial symptom onset and after sufficient time had passed to observe the COVID-19 disease course through resolution of acute illness or death. Data collection began April 1, 2020, and is ongoing. Exposures: Laboratory-positive SARS-CoV-2 infection or highly suspected COVID-19. Main Outcomes and Measures: Clinical outcome with 4 levels of increasing severity: not hospitalized, hospitalization only, admission to the intensive care unit and/or required ventilator support, and death. Results: Of 1626 patients, most had laboratory-positive SARS-CoV-2 infection (1345 [82.7%]), were female (1202 [74.0%]), and had relapsing-remitting MS (1255 [80.4%]). A total of 996 patients (61.5%) were non-Hispanic White, 337 (20.8%) were Black, and 190 (11.7%) were Hispanic/Latinx. The mean (SD) age was 47.7 (13.2) years, and 797 (49.5%) had 1 or more comorbidity. The overall mortality rate was 3.3% (95% CI, 2.5%-4.3%). Ambulatory disability and older age were each independently associated with increased odds of all clinical severity levels compared with those not hospitalized after adjusting for other risk factors (nonambulatory: hospitalization only, odds ratio [OR], 2.8 [95% CI, 1.6-4.8]; intensive care unit/required ventilator support, OR, 3.5 [95% CI, 1.6-7.8]; death, OR, 25.4 [95% CI, 9.3-69.1]; age [every 10 years]: hospitalization only, OR, 1.3 [95% CI, 1.1-1.6]; intensive care unit/required ventilator support, OR, 1.3 [95% CI, 0.99-1.7]; death, OR, 1.8 [95% CI, 1.2-2.6]). Conclusions and Relevance: In this registry-based cross-sectional study, increased disability was independently associated with worse clinical severity including death from COVID-19. Other risk factors for worse outcomes included older age, Black race, cardiovascular comorbidities, and recent treatment with corticosteroids. Knowledge of these risk factors may improve the treatment of patients with MS and COVID-19 by helping clinicians identify patients requiring more intense monitoring or COVID-19 treatment.

Perceptions of risk and adherence to care in MS patients during the COVID-19 pandemic: A cross-sectional study.

BACKGROUND: The COVID-19 pandemic has raised concerns for increased risk of infection in patients with multiple sclerosis (MS) and disrupted their routine MS care. The aim of this study is to characterize the extent of MS patients' perceptions of risk and adherence to care during the pandemic. METHODS: A survey was emailed to patients from a large MS center in New York City during the local peak of the pandemic to assess perceptions of infection risk and adherence to MS care including appointments, laboratory studies, MRIs, and taking disease-modifying therapies (DMT). RESULTS: 529 patients from the MS center responded to the survey during two weeks in April 2020. Patients collectively showed concern about becoming infected with COVID-19 (88%) and perceived a higher infection risk due of having MS (70%) and taking DMTs (68%). Patients frequently postponed appointments (41%), laboratory studies (46%), and MRIs (41%). Noncompliance with DMTs was less common (13%). Decisions to alter usual recommendations for care were made by the patient more often than by the provider regarding adherence to appointments (68%), laboratory studies (70%), MRI (67%), and DMT (65%). Degree of concern for infection was associated with adherence to appointments (p=0.020) and laboratory studies (p=0.016) but not with adherence to MRI and DMTs. Thirty-five patients reported being tested for COVID-19, of whom fourteen reported a positive test. CONCLUSION: Patients with MS were highly concerned about becoming infected during the local peak of the COVID-19 pandemic. Behaviors that deviated from originally recommended MS care were common and often self-initiated, but patients were overall compliant with continuing DMTs.

The emotional impact of the COVID-19 pandemic on individuals with progressive multiple sclerosis.

OBJECTIVE: Individuals with pre-existing chronic illness have shown increased anxiety and depression due to COVID-19. Here, we examine the impact of the COVID-19 pandemic on emotional symptomatology and quality of life in individuals with Progressive Multiple Sclerosis (PMS). METHODS: Data were obtained during a randomized clinical trial on rehabilitation taking place at 11 centers in North America and Europe. Participants included 131 individuals with PMS. Study procedures were interrupted in accordance with governmental restrictions as COVID-19 spread. During study closure, a COVID Impact Survey was administered via telephone or email to all participants, along with measures of depressive symptoms, anxiety symptoms, quality of life, and MS symptomatology that were previously administered pre-pandemic. RESULTS: 4% of respondents reported COVID-19 infection. No significant changes were noted in anxiety, quality of life, or the impact of MS symptomatology on daily life from baseline to lockdown. While total HADS-depression scores increased significantly at follow-up, this did not translate into more participants scoring above the HADS threshold for clinically significant depression. No significant relationships were noted between disease duration, processing speed ability or EDSS, and changes in symptoms of depression or anxiety. Most participants reported the impact of the virus on their psychological well-being, with a little impact on financial well-being. The perceived impact of the pandemic on physical and psychological well-being was correlated with the impact of MS symptomatology on daily life, as well as changes in depression. CONCLUSIONS: Overall, little change was noted in symptoms of depression or anxiety or overall quality of life.
