8 Ipilimumab诱导的转移性黑色素瘤患者自身免疫性全血细胞减少症(血液系统)(造血生长因子、IVIg)

Pauline du Rusquec等人报道1例77岁的转移性黑色素瘤患者在第4次注射Ipilimumab(抗CTLA-4抗体)治疗8天之后出现自身免疫性全血细胞减少症(贫血、血小板减少和中性粒细胞减少症)的病例。该患者的全血细胞减少症对高剂量的口服糖皮质激素(1mg/kg)和造血生长因子的治疗无效,最终在静脉注射免疫球蛋白(IVIg)后得以缓解。

【精评】血液系统不良反应是Ipilimumab治疗的一项迟发性毒副反应,在既往的文献中有过两例类似的报告,其治疗均使用了IVIg。Ipilimumab具有延迟效应,其不良反应也是如此;由于IVIg的平均血浆半衰期为2~4周,这可能是全血细胞减少复发的原因。对于对皮质类固醇耐药的患者,尽早使用IVIg或许可以使患者获益。
