ANN ONCOL:PD1抗体相关炎性胃肠道疾病

2017-12-01 MedSci MedSci原创

免疫靶点抑制剂在肿瘤患者中具有临床活性,但是免疫相关不良反应限制了其发展。ANN ONCOL近期发表了一篇文章,研究肿瘤患者接受抗PD-1治疗的胃肠道免疫相关不良反应(GI-irAE)

免疫靶点抑制剂在肿瘤患者中具有临床活性,但是免疫相关不良反应限制了其发展。ANN ONCOL近期发表了一篇文章,研究肿瘤患者接受抗PD-1治疗的胃肠道免疫相关不良反应(GI-irAE)。

作者回顾性分析了2013年到2016年间由于接受抗PD-1抗体治疗而可疑有胃肠道免疫相关不良反应的患者。患者数据由消化内科医生,肿瘤科医生和病理科医生等共同评估。最终44例患者因可疑胃肠道免疫相关不良反应进入消化内科就诊。20例患者确诊存在于抗PD-1治疗相关的胃肠道免疫相关不良反应,不良反应在抗PD-1治疗开始后4.2个月出现。抗PD-1治疗胃肠道免疫相关不良反应发生率约为1.5%。出现胃肠道免疫相关不良反应的患者主要的症状是腹泻(n=16),腹痛(n=13),恶心呕吐(n=11),小肠梗阻(n=1)和便血(n=2)。无患者接受结肠切除术。共观察到4种胃肠道免疫相关不良反应:急性结肠炎(n=8),镜下结肠炎(n=7),上消化道炎症(n=4)和假性梗阻(n=1)。急性肠炎对糖皮质激素反应率为87.5%,镜下肠炎为57%,上消化道炎症为75%。急性结肠炎治愈平均时间为36天,镜下结肠炎为98天。

文章最后认为,与抗CTLA-1相关,抗PD-1治疗胃肠道免疫相关不良反应不同且发病率更低。
