Lancet:促性腺激素治疗用于氯米芬无效的去甲促性腺激素性不孕症患者

2017-12-20 zhangfan MedSci原创

研究认为,对于氯米芬无效的去甲促性腺激素性不孕症患者,促性腺激素治疗的效果优于持续的氯米芬治疗

在许多国家,氯米芬是去甲促性腺激素性不孕症(即无排卵或不规律排卵)的首选治疗方法。若患者服用几个疗程的氯米芬后排卵但仍不受孕,通常会进行促性腺激素联合或不联合子宫内授精。近日研究人员比较了促性腺激素、持续氯米芬治疗、宫内受精以及自然受精对去甲促性腺激素性不孕症的治疗效果。

18岁以上,6次氯米芬治疗后排卵正常的去甲促性腺激素性不孕症患者参与研究。患者随机接受6轮的促性腺激素治疗联合宫腔内人工授精、6轮的促性腺激素治疗联合自然授精、6轮的氯米芬治疗联合宫腔内人工授精、6轮的氯米芬治疗联合自然授精。氯米芬的剂量为50-150mg每日,促性腺激素的剂量为50或75 IU每日。研究的主要终点是8个月后活胎率。

研究招募666名参与者,其中促性腺激素联合宫腔内人工授精组166人、促性腺激素联合自然授精组165人、氯米芬联合宫腔内人工授精组163人、氯米芬联合自然授精组172人。研究发现促性腺激素组活胎率高于氯米芬组(167 / 327 [52%] vs 138/334 [41%], RR 1.24 [95% CI 1.05-1.46])。人工受精相比自然受精不能增加活胎率(161 [49%] vs 144 [43%], RR 1.14 [95% CI 0.97-1.35])。组间多胎妊娠率较低且无显著差异。主要发生了3起不良事件:氯米芬组发生1例先天畸形和1例死胎;促性腺激素组发生1例治疗导致的宫颈功能不全死胎早产。

研究认为,对于氯米芬无效的去甲促性腺激素性不孕症患者,促性腺激素治疗的效果优于持续的氯米芬治疗。
