【1】缬昔洛韦用于阻止妊娠早期巨细胞病毒的母婴传播

DOI:https://doi.org/10.1016/S0140-6736(20)31868-7

巨细胞病毒感染一种常见的先天性感染,原发性母体感染后,后代发病率较高,近日研究人员考察了缬昔洛韦阻止巨细胞病毒妊娠早期母亲原发性感染向胎儿垂直传播的效果。

90名患者参与研究,其中缬昔洛韦组45名患者(均为单胎),安慰剂组的45名患者(43名单胎和2对双胞胎),患者年龄在18岁或以上,在怀孕前或怀孕前三个月确诊的原发性巨细胞病毒感染,随机口服缬昔洛韦(每天8克,每天两次)或安慰剂,随访到孕21-22周后进行羊膜穿刺。研究的主要终点是巨细胞病毒垂直传播率。在缬昔洛韦组,45例患者经羊膜穿刺术后,有5例(11%)胎儿巨细胞病毒呈阳性,而安慰剂组的47例患者,羊膜穿刺术后有14例(30%)胎儿呈阳性(巨细胞病毒垂直传播的比值比0.29)。妊娠早期原发性巨细胞病毒感染患者中,缬昔洛韦组2例巨细胞病毒羊膜穿刺呈阳性,明显低于安慰剂组的11例(11% vs 48%)。组间无临床意义的不良事件报告。

【2】米非司酮联合米索前列醇治疗稽留流产

DOI:https://doi.org/10.1016/S0140-6736(20)31788-8

抗孕酮药物米非司酮和前列腺素类似物米索前列醇是治疗稽留流产的常见药物,近日研究人员考察了米非司酮联合米索前列醇对稽留流产的治疗效果。

MifeMiso研究在英国28家医院进行。16岁及以上,经盆腔超声检查诊断为稽留流产患者随机接受单剂量口服200mg米非司酮或安慰剂,两天后分别给予阴道、口服或舌下含服800μg米索前列醇。研究的主要结果是7天内流产失败率,定义为妊娠囊未自然排出。711名女性参与研究,其中米非司酮-米索前列醇组357例,安慰剂-米索前列醇组354例,98%的参与者完成研究。米非司酮-米索前列醇组348名参与者中有59名(17%)在7天内妊娠囊未自然排出,而安慰剂-米索前列醇组348名参与者中有82名(24%)妊娠囊未自然排出(风险比[RR]0.73)。米非司酮加-米索前列醇组355名参与者中有62名(17%)需要手术干预以完成流产,而安慰剂-米索前列醇组353名参与者中有87名(25%)需要手术治疗(0.71)。组间不良事件发生率没有差异。

【3】心肌肌球蛋白抑制剂Mavacamten治疗梗阻性肥厚型心肌病

DOI:https://doi.org/10.1016/S0140-6736(20)31792-X

心肌过度收缩是肥厚型心肌病重要的病理特征,并且是左心室流出道(LVOT)阻塞的主要决定因素。目前肥厚型心肌病的可用药物少且耐受性差,并且缺乏疾病特异性。近日研究人员评估了心肌肌球蛋白抑制剂mavacamten用于有症状的梗阻性肥厚型心肌病中的疗效和安全性。

EXPLORER-HCM研究在13个国家的68个血管中心开展,LVOT压力差≥50 mmHg,NYHA II-III级的肥厚型心肌病患者分为mavacamten组(起始剂量 5 mg)或安慰剂组,持续治疗30周。主要终点是耗氧量峰值(pVO2)每分钟增加≥1.5 mL/kg,且NYHA等级至少降低一次,或pVO2增加≥3.0 mL/kg且NYHA等级无恶化。次要终点是运动后LVOT梯度、pVO2、NYHA等级、KCCQ-CSS评分和HCMSQ-SoB评分的变化。

251位患者参与研究,随机分至mavacamten组(123人)和安慰剂组(128人)。mavacamten组有45位患者(37%)、安慰剂组有22位(17%)患者符合主要终点(差值 +19.4%)。与安慰剂组相比,mavacamten组患者的运动后LVOT梯度降低的幅度更大(-36 mm Hg)、pVO2增加更多(+1.4 mL/kg per min),症状评分也提高更多(KCCQ-CSS +9.1; HCMSQ-SoB -1.8)。Mavacamten组有80位患者的NYHA等级至少提高了一级,而安慰剂组仅40位。两组的安全性和耐受性相似。需紧急治疗的不良反应一般较轻微。安慰剂组一位患者猝死。
