儿童多系统炎症综合征 (MIS-C) 是 SARS-CoV-2 感染的一种罕见并发症,可导致儿科人群出现严重疾病,但我们对这种综合征的了解还处于起步阶段。 2020 年利用免疫分析的转化研究为 MIS-C 的进一步发现奠定了基础。儿童多系统炎症综合征(MIS-C)的免疫反应似乎与急性 SARS-CoV-2 感染期间的免疫反应不同,但与川崎病相比既有共同的特征,又有不同的特征。 MIS-C 病程中的免疫状况发生变化,急性期的特点是先天免疫细胞激活以及 T 细胞和 B 细胞淋巴细胞减少,这些在恢复过程中恢复正常,并检测到针对 SARS-CoV-2 的适当抗病毒抗体反应(参考文献)。 MIS-C 和川崎病可能具有相同的血浆蛋白谱,但自身抗体靶点不同;它们是不同的还是代表同一临床综合征的连续体仍有待确定。
Multisystem inflammatory syndrome in children (MIS-C) is a rare complication of SARS-CoV-2 infection that can result in serious illness in the paediatric population but our understanding of this syndrome is in its infancy. Translational studies in 2020 leveraging immune profiling have laid the foundation to enable further discovery in MIS-C. The immune response in multisystem inflammatory syndrome in children (MIS-C) seems to be distinct from that during acute SARS-CoV-2 infection, but has both shared and distinct features compared with Kawasaki disease. The immune landscape shifts during the course of MIS-C, with the acute phase being characterized by activated innate immune cells and T cell and B cell lymphopenia, which normalize during recovery, and appropriate anti-viral antibody responses detected to SARS-CoV-2 (ref.). MIS-C and Kawasaki disease might share plasma protein profiles but differ in autoantibody targets; whether they are distinct or represent a continuum of the same clinical syndrome remains to be determined.
