Circulation:卡纳单抗抗炎治疗可预防心力衰竭住院

2018-11-12 xing.T MedSci原创

这项随机、双盲、安慰剂对照试验的数据表明,在hsCRP升高的既往MI患者中,使用IL-1β抑制剂卡纳单抗治疗与心力衰竭住院治疗以及心力衰竭住院或心力衰竭相关死亡的复合事件的剂量依赖性减少有关。

临床炎症与心力衰竭风险增加,以及与已发生心力衰竭患者预后不良有关。然而,专门针对减少心力衰竭患者炎症的治疗尚未发现改善的临床结局。近日,血管领域权威杂志Circulation上发表了一篇研究文章,研究人员检验了IL-1β抑制剂卡纳单抗可以预防心力衰竭住院治疗(HHF)和HHF或心力衰竭相关死亡复合事件的假设。

研究人员将10061例既往心肌梗死(MI)和高敏C反应蛋白(hsCRP)≥2mg/L的患者随机分为卡纳单抗50mg、150mg、300mg或安慰剂治疗,每三个月皮下注射一次。总共有2173例(22%)患者报告了基线时存在心力衰竭病史。研究人员检验了卡纳单抗预防HHF事件和HHF或心力衰竭相关死亡复合事件的假设。

该研究共有385名患者在中位随访3.7年期间发生HHF事件。发生HHF的患者年龄较大,体重指数较高,更可能患有糖尿病高血压和既往冠状动脉搭桥手术。正如预期的那样,在随访期间发生HHF的患者hsCRP的基线浓度中位数(Q1,Q3)高于没有HHF的患者[分别为5.7mg/L(3.5-9.9)vs. 4.2mg/L(2.8-6.9),P<0.0001]。与安慰剂相比,卡纳单抗每增加一个剂量的HHF未调整风险比(95%CI),对于50mg为1.04(0.79-1.36),对于150mg为0.86(0.65-1.13),对于300mg为0.76(0.57-1.01)(趋势P=0.025)。卡纳单抗也降低了HHF或HF相关死亡的复合事件,50mg的未调整风险比(95%CI)为1.00(0.78-1.30),150 mg为0.87(0.67-1.12),300mg为0.78(0.60-1.01)(趋势P=0.037)。

这项随机、双盲、安慰剂对照试验的数据表明,在hsCRP升高的既往MI患者中,使用IL-1β抑制剂卡纳单抗治疗与心力衰竭住院治疗以及心力衰竭住院或心力衰竭相关死亡的复合事件的剂量依赖性减少有关。
