The effect of coronavirus disease (COVID-19) on the risk of relapse in multiple sclerosis (MS) have been unknown. In this retrospective study of 41 relapsing-remitting MS patients, number of relapses in pre-defined at risk-period (ARP) was compared with the previous two years. During the previous two years, a total of 32 attacks was reported, which 5 (15.6%) were during the at-risk period. After adjusting for age and sex, there was an increased risk of attack during ARP compared to the previous two years (RR: 2.566, 95%CI: 1.075-6.124, P=0.034). Our preliminary study suggested that COVID-19 can trigger exacerbation of MS.
新冠病毒疾病(COVID-19)对多发性硬化症(MS)复发风险的影响尚不清楚。在这项对 41 例复发缓解型 MS 患者的回顾性研究中,比较了预先定义的风险期(ARP)内的复发次数与前两年的情况。在过去两年中,共报告了 32 次发作,其中 5 次(15.6%)发生在风险期内。在调整年龄和性别后,ARP 期间的发作风险高于前两年(RR:2.566,95%CI:1.075-6.124,P=0.034)。我们的初步研究表明,COVID-19 可能引发 MS 恶化。
