Abstract
Background Multisystem inflammatory syndrome in children(MIS-C),a relatively uncommon but severe pediatric compli-cation,is associated with coronavirus disease 2019(COVID-19).A variety of treatment approaches,including intravenous immunoglobulins(IVIGs),glucocorticoids(GCs)and biologic agents,such as anakinra and infliximab,have been described for the management of COVID-19-related MIS-C.Anticoagulant therapy is also important.However,a well-developed treatment system has not been established,and many issues remain controversial.Several recently published articles related to the treatment of MIS-C have been released.Hence,in this review,we identified relevant articles published recently and summarized the treatment of MIS-C more comprehensively and systematically.Data sources We reviewed the literature on the treatment of MIS-C through 20 September 2023.The PubMed/Medline,Web of Science,EMBASE,and Cochrane Library databases were searched with the combination of the terms"multisystem inflammatory syndrome","MIS-C","PIMS-TS","therapy","treatment","drug","IVIG","GCs","intravenous immuno-globulin","corticosteroids","biological agent",and"aspirin".Results The severity of MIS-C varies,and different treatment schemes should be used according to the specific condition.Ongoing research and data collection are vital to better understand the pathophysiology and optimal management of MIS-C.Conclusions MIS-C is a disease involving multiple systems and has great heterogeneity.With the accumulation of additional experience,we have garnered fresh insights into its treatment strategies.However,there remains a critical need for greater standardization in treatment protocols,alongside the pressing necessity for more robust and meticulously conducted studies to deepen our understanding of these protocols.
