A cross-sectional hospital records-based study was conducted to evaluate the prevalence, severity, outcomes, and identify demographic and clinical risk factors of coronavirus disease (COVID-19) in patients with MS. The study was conducted at multiple clinics in Oman, Kuwait, and the United Arab Emirates (UAE) from March 2020 to February 2021. The association of patient demographics, MS disease characteristics, and use of disease-modifying therapies with outcomes of COVID-19 illness were evaluated using odds ratio. A total of 134 MS patients with COVID-19 (prevalence rate of 3.7%) having a median age of 35.5 years were analyzed in the study. A majority (126 [94.0%]) of patients had mild COVID-19 illness and 122 (91.0%) made a full recovery, while 1 (0.7%) patient died. The median EDSS score reported in the study was low (1.0). Univariate regression analysis showed high EDSS scores, progressive MS disease, and use of anti-CD20 therapy such as rituximab as risk factors for moderate to severe COVID-19 requiring hospitalization. Comorbidities were associated with a higher risk of non-recovery from COVID-19 in both univariate and multivariate analyses. Age, sex, smoking history, and duration of MS did not show a significant association with severity or adverse COVID-19 disease outcome. Identification of risk factors can aid in improving the treatment and monitoring of pwMS and COVID-19., (Copyright © 2022 The Authors. Published by Elsevier Ltd.. All rights reserved.)

This article describes consensus recommendations from an expert group of neurologists from the Arabian Gulf region on the management of relapsing multiple sclerosis (RMS) in the COVID-19 era. MS appears not to be a risk factor for severe adverse COVID-19 outcomes (though patients with advanced disability or a progressive phenotype are at higher risk). Disease-modifying therapy (DMT)-based care appears generally safe for patients with MS who develop COVID-19 (although there may be an increased risk of adverse outcomes with anti-CD20 therapy). Interferon-β, teriflunomide, dimethyl fumarate, glatiramer acetate, natalizumab and cladribine tablets are unlikely to increase the risk of infection; fingolimod, anti-CD20 agents and alemtuzumab may confer an intermediate risk. Existing DMT therapy should be continued at this time. For patients requiring initiation of a DMT, all currently available DMTs except alemtuzumab can be started safely at this time; initiate alemtuzumab subject to careful individual risk-benefit considerations. Patients should receive vaccination against COVID-19 where possible, with no interruption of existing DMT-based care. There is no need to alter the administration of interferon-β, teriflunomide, dimethyl fumarate, glatiramer acetate, natalizumab, fingolimod or cladribine tablets for vaccination; new starts on other DMTs should be delayed for up to 6 weeks after completion of vaccination to allow the immune response to develop. Doses of the Oxford University/AstraZeneca vaccine may be scheduled around doses of anti-CD20 or alemtuzumab. Where white cell counts are suppressed by treatment, these should be allowed to recover before vaccination., (© 2021. The Author(s).)
