Lancet:硝苯地平 VS. 阿托西班治疗先兆早产的效果和安全性(APOSTEL III)

先兆早产以及晚产48小时的孕妇可在产前使用糖皮质激素以改善新生儿结局。为此,往往会给予安胎药治疗48 h;然而,在改善母婴结局上哪些药物的效果最好尚没有达成共识。本次APOSTEL III期试验旨在比较钙通道阻滞剂硝苯地平和催产素抑制剂阿托西班治疗先兆早产女性的有效性和安全性。

先兆早产以及晚产48小时的孕妇可在产前使用糖皮质激素以改善新生儿结局。为此,往往会给予安胎药治疗48 h;然而,在改善母婴结局上哪些药物的效果最好尚没有达成共识。本次APOSTEL III期试验旨在比较钙通道阻滞剂硝苯地平和催产素抑制剂阿托西班治疗先兆早产女性的有效性和安全性。

采用多中心双盲随机对照试验设计,共纳入510名先兆早产孕妇(孕周25–34周),1:1随机分配至硝苯地平(254名)或阿托西班(256名)治疗组,治疗48小时。主要结果为不良围产期结局的复合情况,包括围产期死亡率、婴儿支气管肺发育不良、败血症、颅内出血、脑室周围白质软化,及坏死性肠炎。

最终硝苯地平治疗组共有248名女性及297名婴儿可供分析,阿托西班治疗组共有255名女性及294名婴儿可供分析。硝苯地平组共有42名(14%)婴儿发生了研究主要结果,阿托西班治疗组共有45名(15%)婴儿发生了研究主要结果。硝苯地平组16名(5%)婴儿死亡,阿托西班治疗组7名(2%)婴儿死亡;这些死亡事件与药物的使用并无关系。两组之间产妇不良事件的发生并无差异。

总而言之,对于先兆早产的孕妇,使用48h的硝苯地平或阿托西班其围产期结局类似。未来仍需要大型的安慰剂对照试验以探究围产期结局的差异。
