Although it is estimated that COVID-19 life-threatening conditions may be diagnosed in less than 1:1000 infected individuals below the age of 50, but the real impact of this pandemic on pediatric patients with different types of primary immunodeficiency (PID) is not elucidated. The current prospective study on a national registry of PID patients showed that with only 1.23 folds higher incidence of infections, these patients present a 10-folds higher mortality rate compared to population mainly in patients with combined immunodeficiency and immune dysregulation. Therefore, further management modalities against COVID-19 should be considered to improve the survival rate in these two PID entities using hematopoietic stem cell transplantation and immunomodulatory agents.
尽管据估计,50 岁以下感染人群中危及生命的 COVID-19 病例可能不到千分之一,但这种大流行对不同类型原发性免疫缺陷(PID)的儿科患者的实际影响尚不清楚。目前对 PID 患者国家注册中心的前瞻性研究表明,这些患者的感染发生率仅高出 1.23 倍,但死亡率却比主要为联合免疫缺陷和免疫失调患者的人群高出 10 倍。因此,应考虑进一步采用造血干细胞移植和免疫调节剂等方法来管理 COVID-19,以提高这两种 PID 实体的生存率。
