Outcomes of COVID-19 in PwMS (persons with Multiple Sclerosis) on immunosuppressive therapies, particularly B-cell depletors, can be unpredictable. There has been a concern for postponing or avoiding use of Rituximab (RTX) during the COVID-19 pandemic. We report the course and outcomes of COVID-19 in PwMS receiving RTX.
PwMS receiving RTX who contracted COVID-19 were closely monitored by tele-consultation and/or evaluated during hospital visits. Those requiring hospitalization for oxygen therapy or admission to ICU or expiring due to COVID-19 were considered to have severe disease. Those without desaturation and manageable at home were considered to have mild disease. Disease course and outcomes were noted.
Twelve out of 62 (19.4%) PwMS on RTX therapy developed COVID-19. Four (age 35-49 years; mean 43.5) had severe COVID; three of whom had Secondary Progressive MS (SPMS). One PwMS expired. Two had prolonged fever lasting >1 month. One demonstrated features of SARS-CoV-2 reactivation. Interval from last RTX infusion (average dose 750 mg) to COVID-19 onset ranged 1-4 (mean 3.7) months. Eight PwMS had mild COVID-19 (age 26-54 years; mean 37.7); six had RRMS and two SPMS. RTX dose was lower (average dose 625 mg) and infusion to COVID-19 onset duration was longer, ranging 4-20 (mean 9.5) months. Four patients, two each from mild and severe COVID-19 groups had neurological deterioration, but none had true relapses.
RTX treated PwMS may have unpredictable disease outcomes if they contract COVID-19, but may be at risk of severe disease and persistent infection. In our series higher age, SPMS, shorter interval from RTX infusion to COVID-19 onset and higher dose of RTX were noted amongst those developing severe disease. RTX should be use cautiously during the COVID-19 pandemic and if unavoidable, less frequent and lower doses should be considered. Patients receiving RTX must be counselled to follow strict COVID-19 preventive measures.
COVID-19 在接受免疫抑制治疗的多发性硬化症(MS)患者(即 PwMS)中的结局可能不可预测,尤其是在使用 B 细胞耗竭剂时。在 COVID-19 大流行期间,人们曾担心推迟或避免使用利妥昔单抗(RTX)。我们报告了接受 RTX 治疗的 PwMS 中 COVID-19 的发病过程和结局。
通过远程咨询密切监测接受 RTX 治疗并感染 COVID-19 的 PwMS,并在住院期间或就诊时进行评估。需要吸氧治疗或入住 ICU 或因 COVID-19 而死亡的患者被认为患有重症。那些没有出现低氧血症且可在家中得到控制的患者被认为患有轻症。记录疾病的发病过程和结局。
62 名接受 RTX 治疗的 PwMS 中有 12 名(19.4%)感染了 COVID-19。4 名(35-49 岁;平均 43.5 岁)患者患有重症 COVID;其中 3 名患有继发进展型 MS(SPMS)。1 名 PwMS 死亡。2 名患者持续发热超过 1 个月。1 名患者出现 SARS-CoV-2 再激活的特征。末次 RTX 输注(平均剂量 750mg)至 COVID-19 发病的时间间隔为 1-4 个月(平均 3.7 个月)。8 名 PwMS 患有轻症 COVID-19(26-54 岁;平均 37.7 岁);其中 6 名患有 RRMS,2 名患有 SPMS。RTX 剂量较低(平均剂量 625mg),且从 RTX 输注至 COVID-19 发病的时间间隔较长,范围为 4-20 个月(平均 9.5 个月)。轻症和重症 COVID-19 组各有 2 名患者出现神经功能恶化,但均未发生真正的复发。
如果感染 COVID-19,接受 RTX 治疗的 PwMS 的疾病结局可能不可预测,但可能存在发生重症疾病和持续感染的风险。在我们的研究中,更年轻的年龄、SPMS、从 RTX 输注至 COVID-19 发病的时间间隔较短以及更高剂量的 RTX 与发生重症疾病相关。在 COVID-19 大流行期间应谨慎使用 RTX,如果不可避免,应考虑减少频率和降低剂量。接受 RTX 治疗的患者必须接受咨询,以遵循严格的 COVID-19 预防措施。
