HAEMATOLOGICA:戊型肝炎感染对血液病患者肿瘤治疗方法的影响

2022-07-04 网络 网络

戊型肝炎病毒(HEV)是全球急性肝炎最常见的原因之一,越来越多的报道称戊型肝炎病毒在免疫功能低下的患者中引起慢性感染。但目前对患有潜在血液疾病的患者知之甚少,特别是戊型肝炎感染对肿瘤治疗的影响很少被描

戊型肝炎病毒(HEV)是全球急性肝炎最常见的原因之一,越来越多的报道称戊型肝炎病毒在免疫功能低下的患者中引起慢性感染。但目前对患有潜在血液疾病的患者知之甚少,特别是戊型肝炎感染对肿瘤治疗的影响很少被描述。

在这里,一研究团队通过调查一个大型回顾性单中心队列中治疗过程的频率、剂量调整和延迟以及总死亡率,评估了戊型肝炎感染对血液病患者肿瘤治疗方法的影响。此外,他们还报道了戊型肝炎的临床病程以及化疗后随访期间的病毒学治疗反应,以及血液病患者病毒学评估的特殊特点。

图1:研究设计和人群的流程图

在这项回顾性单中心分析中,研究团队分析了 35 名血液学戊型肝炎患者,包括 20 名接受积极肿瘤治疗的患者和 15 名接受治疗后随访或接受积极监测的患者。在接受积极肿瘤治疗的大多数患者(60%)中,对肝炎相关的治疗进行了调整,其中 25% 的患者因血液疾病进展而死亡。在同时接受肿瘤治疗的患者中,没有发生与肝炎相关的死亡。

图2:根据cd20指导治疗的HEV清除时间(天)的比较。在接受cd20定向治疗的患者中,A组和B组的HEV清除时间显著延长(p=0.01和p=0.049)

图3:在积极接受cd20定向治疗的患者(A组)和既往使用cd20定向单克隆抗体治疗的患者中,戊型肝炎的临床病程概述

相比之下,随访组中有两名患者死于乙型肝炎相关的慢加急性肝功能衰竭。34% 的病例出现慢性戊型肝炎,43% 的病例接受了利巴韦林治疗,其中 27% 的病例获得了持续的病毒学应答。CD20 导向治疗是发展为慢性戊型肝炎的唯一独立危险因素。

图4:A组中与HEV相关的癌症治疗改变的概述

总的来说,在任何时间点以 CD20 为导向的治疗都是发展为慢性戊型肝炎的危险因素。然而,由于血液疾病进展的死亡率高于戊型肝炎相关的死亡率,研究团队建议根据具体情况谨慎决定癌症治疗的修改,处于治疗后随访阶段的患者也可能患有严重的病程,并且戊型肝炎慢性化的发生频率与接受积极治疗的患者一样频繁。
