BACKGROUND Overt immune activation by viral infections can lead to cytokine storm syndromes, such as hemophagocytic lymphohistiocytosis (HLH) and macrophage activation syndrome (MAS). OBJECTIVE We aim to compare the immune response to different viral pathogens to understand the connection between infections and cytokine storm syndromes. METHODS We recruited children who presented to the emergency room with fever for ≥ 3 days. We performed immune profiling using Olink proximity extension assay and flow cytometry. We compared the findings with cases of HLH, MAS, Kawasaki disease (KD), and multisystem inflammatory syndrome in children (MIS-C). RESULTS We enrolled 352 febrile patients and studied 110 cases with confirmed common viral infections. We found that Epstein-Barr virus (EBV) uniquely triggered high levels of multiple cytokines (IL-18, IL-27, tumor necrosis factor, FLT3 ligand, and lymphotoxin alpha) and IFN-γ-induced chemokines (CXCL9/10/11 and CCL19). These patterns are similar to the hyperinflammatory response associated with HLH / MAS, but less consistent with the findings in KD and MIS-C. Flow cytometry analysis revealed that CD38+HLA-DR+ T lymphocytes, which are pathogenic cells responsible for IFN-γ production in HLH / MAS, are vastly expanded in patients with acute EBV infection. Cell sorting identified CD38+HLA-DR+ T cells as atypical lymphocytes that are classically associated with acute EBV infection. CONCLUSION This work broadens our understanding of common viral infections in children and provides an immunologic basis for the link between EBV infection and HLH / MAS.

过度炎症的特征与 EBV 感染和细胞因子风暴综合征的生物学有关。



背景 病毒感染引起的明显免疫激活可导致细胞因子风暴综合征,例如噬血细胞性淋巴组织细胞增生症 (HLH) 和巨噬细胞活化综合征 (MAS)。目的 我们旨在比较对不同病毒病原体的免疫反应,以了解感染与细胞因子风暴综合征之间的联系。方法 我们招募了因发热 ≥ 3 天到急诊室就诊的儿童。我们使用 Olink 邻近延伸测定和流式细胞术进行免疫分析。我们将研究结果与 HLH 、 MAS 、 川崎病 (KD) 和儿童多系统炎症综合征 (MIS-C) 病例进行了比较。结果 我们招募了 352 例发热患者,并研究了 110 例确诊的常见病毒感染病例。我们发现 Epstein-Barr 病毒 (EBV) 独特触发高水平的多种细胞因子 (IL-18 、 IL-27 、 肿瘤坏死因子 、 FLT3 配体和淋巴毒素 α) 和 IFN γ诱导的趋化因子 (CXCL9/10/11 和 CCL19)。这些模式类似于与 HLH / MAS 相关的过度炎症反应,但与 KD 和 MIS-C 中的发现不太一致。流式细胞术分析显示,CD38+HLA-DR+T 淋巴细胞是 HLH/MAS 中负责产生 IFN-γ 的致病细胞,在急性 EBV 感染患者中大幅扩增。细胞分选确定 CD38+HLA-DR+ T 细胞是非典型淋巴细胞,通常与急性 EBV 感染相关。结论 这项工作拓宽了我们对儿童常见病毒感染的理解,并为 EBV 感染与 HLH / MAS 之间的联系提供了免疫学基础。
