Semin Arthritis Rheu:托珠单抗治疗巨细胞动脉炎的疗效

2019-01-11 xiangting MedSci原创

在临床实践中,TCZ可使难治性GCA快速而持续的改善。

临床试验显示托珠单抗(TCZ)具有治疗巨细胞动脉炎(GCA)的疗效。真实世界的数据很少。这项研究目标是评估临床实践中TCZ对未经选择GCA患者的疗效和安全性。

这是一项观察性、开放标签的多中心研究,来自40个国家级转诊中心的GCA患者,由于既往治疗无效或不良事件接受TCZ治疗。结局变量是临床特征的改善、急性期反应物、糖皮质激素保留作用、缓解延长和复发。进行了以下比较性研究:a)TCZ给药途径(SC vs. IV); b)GCA病程(≤6 vs. > 6个月); c)严重感染(有或没有); d)TCZ起始≤15 vs. >15mg/天。

134例患者的平均年龄为73.0±8.8岁。GCA诊断后开始TCZ治疗的中位[IQR]时间为13.5[5.0-33.5]个月。98例患者(73.1%)接受了免疫抑制剂治疗。TCZ治疗1个月后93.9%的患者临床改善。CRP从1.7[0.4-3.2]降至0.11[0.05-0.5]mg/dL(p<0.0001),ESR从33[14.5-61]降至6[2-12]mm/1st小时(p<0.0001),并观察到贫血患者从16.4%降至3.8%(p<0.0001)。无论给药途径或病程如何,第6、12、18、24个月分别有55%、70.4%、69.2%和90%的患者出现导致缓解的临床改善。最常见的不良副作用是严重感染(10.6/100患者年),与治疗前三个月内泼尼松剂量较高相关。

在临床实践中,TCZ可使难治性GCA快速而持续的改善。严重感染率似乎高于临床试验。
