摘要

目的eb病毒(EBV)是继发性噬血细胞淋巴组织细胞病(HLH)的常见病因。虽然B细胞是eb病毒的宿主,但在这种疾病中,T细胞和NK细胞内的感染很难治疗。方法一名19岁女性,以克罗恩病为背景,有6周的鼻塞症状。检查时,她有发热和心动过速,伴有轻度扁桃体肿大和脾肿大。检测到新的三岁细胞减少和肝酶升高,随后全血PCR证实急性EBV。血清铁蛋白、甘油三酯和可溶性CD25升高,纤维蛋白原低,骨髓中存在噬血细胞现象,进一步支持ebv相关HLH的诊断。结果给予皮质类固醇、IVIG和利妥昔单抗治疗,由于持续发热,随后加用阿那单抗治疗。然后在EBER Flow-FISH实验中证实了EBV感染在CD8+ T细胞内。开始使用Ruxolitinib,第5天患者退烧,其他HLH参数有所改善。她在住院39天后出院。迄今为止,尽管在HLH恢复期发生了COVID-19感染,但她的HLH仍处于缓解期。结论EBV病毒血症需要适当的治疗来控制EBV相关的HLH,因为美罗昔单抗可能不足,皮质类固醇耐药可导致CD8+ T细胞持续感染EBV。这种实体被称为t细胞- ebv - hlh。Ruxolitinib在这种特殊情况下是一种新的治疗策略,具有几个优点,包括抑制皮质类固醇耐药,促进ebv感染的T细胞凋亡。

A case of T-cell-Epstein–Barr virus-haemophagocytic lymphohistiocytosis and sustained remission following ruxolitinib therapy

A case of T-cell-Epstein–Barr virus-haemophagocytic lymphohistiocytosis and sustained remission following ruxolitinib therapy
Epstein–Barr virus (EBV) is a common cause of secondary haemophagocytic lymphohistiocytosis (HLH). While B cells are reservoirs for EBV, infection within T cells and NK cells in this disease can be difficult to treat.
