Bsteh G, Bitschnau C, Hegen H, Auer M, Di Pauli F, Rommer P, Deisenhammer F, Berger T. Multiple sclerosis and COVID-19: how many are at risk? Eur J Neurol. 2020 Sep 25. doi: 10.1111/ene.14555. 

Background: The COVID-19 pandemic challenges neurologists in counselling multiple sclerosis (MS) patients with respect to their risk for and by SARS-CoV-2 and in guiding disease-modifying treatment (DMT). The objective was to determine the frequency and distribution of currently known risk factors for COVID-19 mortality in a MS population.

Methods: MS patients with at least one complete case report between January 1st , 2015 and December 31st , 2019 from the Innsbruck MS database (IMSD) were cross-sectionally included. Frequencies of currently estimated COVID-19 mortality risk factors were analyzed and the cumulative risk was calculated by a recently developed score. For every risk group, the proportions of patients under DMT and immunosuppressive treatment were determined.

Results: Of 1931 MS patients, 63.4% had low risk of COVID-19 mortality, 26% had mild risk, 8.8% had a moderate risk, while a combined 0.9% had high or very high risk of COVID-19 mortality. Of the patients at high or very high risk, only one patient received DMT and none had an immunosuppressive therapy.

Conclusions: In a population-based MS cohort, the proportion of patients at high risk of COVID-19 mortality is below 1%. Importantly, the vast majority of these MS patients did not receive any DMT.

Vogel AC, Schmidt H, Loud S, McBurney R, Mateen FJ. Impact of the COVID-19 pandemic on the health care of >1,000 People living with multiple sclerosis: A cross-sectional study. Mult Scler Relat Disord. 2020 Sep 19;46:102512. doi: 10.1016/j.msard.2020.102512

Background: People with multiple sclerosis (PwMS) experienced changes in health behaviors and access to MS care due to the COVID-19 pandemic. The USA has the highest recognized number of Covid19 infections globally. The extent of the impact of COVID-19 has not been well characterized in large samples of PwMS to date. The MS patient perspective on COVID-19 would complement the physician-reported cases of MS and COVID-19 in the literature.

Methods: A cross-sectional survey of adult PwMS was performed online, using the U.S.-based patient-powered iConquerMS™ platform, in April 2020.

Results: There were 1,145 respondents (response rate: 20%). 1,019 had a diagnosis of MS and responded completely (average age: 54.2 years, range: 20-81; 79% female; 64% relapsing remitting, 22% secondary progressive, 12% primary progressive; 88% in the USA). 748 (73%) used a DMT in the last year, primarily higher-efficacy therapies: ocrelizumab (n=238), dimethyl fumarate (n=85), fingolimod (n=80). The most frequent comorbidities were depression (41%), hypertension (26%), and asthma (12%). Women were more worried than men about COVID-19 (p=0.001); non-white-identifying PwMS believed it was a greater danger to their health than white-identifying PwMS (p=0.002). Through the continuum of symptoms to care, 61% of PwMS (n=617) reported symptoms associated with COVID-19, 39% (n=395) knew someone exposed to COVID-19, 4% (n=38) were aware of a personal COVID-19 exposure, 13% (n=128) wanted testing for COVID-19 but could not access it, and 4% (n=43) were tested. Specific to their MS care, 64% (n=650) canceled a medical visit, 22% (n=222) canceled a neurologist visit, 11% (n=112) canceled an MRI, 21% (n=212) canceled a laboratory test, and 10% (n=98) changed their DMT in some way due to COVID19 including 65 delaying at least one dose. 37% (n=382) had a telehealth visit due to COVID-19. 37% of PwMS (n=374) experienced employment changes, most commonly working from home (n=194) and having work hours reduced (n=65) while 32 lost their jobs. Of the 7 cases who tested positive for COVID-19 (<1% of participants) (5 female; age range: 29-64 years), DMTs included dimethyl fumarate (n=2), ocrelizumab (n=1), rituximab (n=1), and a clinical trial drug (n=1).

Conclusions: A majority of people with MS reported interruptions to their MS care along the MS care pathway alongside limited access to COVID-19 testing. Postponements and delays in care were common with 10% of participants reporting a change in their DMT administration. Less than 1% of this self-referred convenience online cohort had a positive test for COVID-19 although more than half reported symptoms that are associated with COVID-19.

  • Interesting. I wonder what risk score the first study used. I would like to know my risk score it would help very much with occupational health and my work!
