There was an outbreak of pediatric multisystem inflammation syndrome (PMIS) was observed in multiple countries recently, and this syndrome was suspected to be associated with SARS-CoV-2 infection. At present, there is still no standardized diagnostic criteria and treatment regimen for PMIS, while the etiology and pathogenesis still remain unclear.
We performed a systematic review on PubMed and Embase from the time of inception to June 24th 2020 in order to find relevant cases.
There are seven studies included, and 80% of patients suffered persistent fever and 90% appeared gastrointestinal symptoms. IgG antibody against SARS-CoV-2 was positive on 81% of patients, while 37% of the patients were nucleic acid positive. C-reactive protein, IL-6 and PCT were elevated and intravenous immunoglobulin was a routine treatment for PMIS. There were more than half of patients required inotropic supports and mechanical ventilation were applied to 33% of patients. The median length of hospital stay was 10.66 days and 74% had admitted to accept intensive care.
Our study documented three common types of PMIS clinical presentation: persistent fever and gastrointestinal symptoms, shocked with heart dysfunction and Kawasaki disease-like syndrome. PMIS patients proved with a marked inflammatory state were possibly associated with SARS-CoV-2 infection.
最近多个国家观察到小儿多系统炎症综合征(PMIS)的爆发,该综合征疑似与 SARS-CoV-2 感染有关。目前,PMIS 尚无标准化的诊断标准和治疗方案,其病因和发病机制仍不清楚。
我们对从创建到 2020 年 6 月 24 日在 PubMed 和 Embase 上进行了系统回顾,以寻找相关病例。
共纳入 7 项研究,80%的患者持续发热,90%的患者出现胃肠道症状。81%的患者 SARS-CoV-2 抗体 IgG 阳性,37%的患者核酸阳性。C 反应蛋白、IL-6 和 PCT 升高,静脉注射免疫球蛋白是 PMIS 的常规治疗方法。超过一半的患者需要正性肌力支持,33%的患者需要机械通气。中位住院时间为 10.66 天,74%的患者接受重症监护。
本研究记录了 PMIS 的三种常见临床表现类型:持续发热和胃肠道症状、伴有心功能障碍的休克和川崎病样综合征。PMIS 患者表现出明显的炎症状态,可能与 SARS-CoV-2 感染有关。
