摘要: 目的 研究复发难治B细胞血液系统恶性肿瘤患者接受靶向CD19的嵌合抗原受体T细胞(chimeric antigen receptor T cell,CAR-T)治疗后出现的凝血功能变化情况及相关因素分析。方法 评估2016年10月~2020年1月46例复发难治B细胞血液系统恶性肿瘤患者接受靶向CD19 CAR-T治疗后凝血功能变化及其相关因素分析。结果 46例患者凝血功能异常为37例(80.4%),包括D-二聚体>5 mg/L(31/46, 67.4%)、凝血酶原时间延长超过正常值>3 s(7/46, 15.2%)、部分凝血活酶时间延长超过正常值>10 s(25/46, 54.3%)、凝血酶时间延长(19/46, 41.3%)、纤维蛋白原<1.5 g/L(22/46, 47.8%)以及纤维蛋白原降解产物>20 mg/L(12/18, 66.7%)。相关因素分析提示凝血指标的变化与回输方式、输注后的炎症因子水平及输注后出现的细胞因子释放综合征(cytokine release syndrome, CRS)严重程度相关。结论 CAR-T治疗可影响患者凝血功能,逐步递增分次回输可以减轻输注后的凝血功能异常,CRS的严重程度与凝血功能异常密切相关。

Abstract: Objective To explore coagulation disorder and relevant factors in patients with B cell hematological malignancies after CD19 targeted chimeric antigen receptor (CAR)-T cell therapy. Methods We retrospectively enrolled 46 patients with relapsed/refractory (R/R) B cell hematological malignancies from October 2016 to January 2020, and the changes of coagulation parameters after CAR-T therapy were collected and analyzed. Results Among 46 patients, 37 (80.4%) patients occurred coagulation disorders, including elevated D-dimer [ (>5 mg/L) (31/46, 67.4%)], prolonged APTT [ (> 10s) (25/46, 54.3%)], prolonged TT (19/46, 41.3%), decreased fibrinogen concentration [(<1.5 g/L) (22/46, 47.8%)], prolonged PT [ (>3s) (7/46, 15.2% )], and elevated FDP [ (> 20 mg/L (12/18, 66.7%)). Correlation analysis showed that coagulation disorder were associated with dose escalation, the level of inflammatory factors after infusion, and the severity of cytokine release syndrome (CRS) after infusion. Conclusion Coagulation disorder is a common adverse event after CAR-T therapy. Dose escalation infusion can reduce the risk of coagulopathy, and the severity of CRS is significantly associated with coagulopathy.
