Aliment Pharm Ther:接受联合疗法的炎性肠炎患者:硫唑嘌呤减量有效吗?

2017年7月,发表在《Aliment Pharmacol Ther》的一项由法国和美国科学家进行的开放标签、前瞻性、随机临床试验考察了联合治疗的炎性肠病(IBD)患者中,硫唑嘌呤(AZA)剂量减少的效果。



2017年7月,发表在《Aliment Pharmacol Ther》的一项由法国和美国科学家进行的开放标签、前瞻性、随机临床试验考察了联合治疗的炎性肠病(IBD)患者中,硫唑嘌呤(AZA)剂量减少的效果。

背景:英夫利昔单抗(IFX)联合AZA治疗IBD比IFX单药更有效。

目的:考察接受联合治疗时,达到疗效所需的AZA最佳剂量。

方法:在一项为期1年的开放标签、前瞻性试验中,纳入使用联合疗法的持久缓解的IBD患者,这些患者被分为3组:AZA稳定组(2.5 mg/kg/天,n=28)vs AZA减量组(剂量减半1~1.25 mg/kg/天,n=27)vs AZA停药组(n=26)。主要终点为治疗失败,定义为出现临床复发和/或IBD治疗发生任何变化。

结果:纳入81例患者。AZA稳定组、AZA减量组和AZA停药组分别有5例(17.9%)、3例(11.1%)和8例(30.8%)患者经历治疗失败(组间P=0.1)。AZA稳定组(3.65 vs 3.45 μg/mL,P=0.9)和AZA减量组(3.95 vs 3.60 μg/mL,P=0.5)纳入时IFX的中位谷浓度与随访结束时相似,而在AZA停药组这一水平从4.25 μg/mL下降至2.15 μg/mL(P=0.02)。AZA稳定组、AZA减量组、AZA停药组分别有4例(14.3%)、4例(14.8%)和11例(42.3%)患者经历IFX药动学的不良进展。6-TGN<105 pmoles/8.108 RBC的阀值与IFX药动学的不良进展相关。

结论:在联合治疗下,AZA减量但不停药似乎与全剂量AZA持续一样有效。
