Hypertension:子痫前期与妊娠相关的急性肾脏损伤危险因素和肾脏结局

2019-10-02 xing.T MedSci原创

总之,子痫前期在女性中很常见,并且相关的母婴死亡率很高。只有三分之二的妇女已确认肾脏恢复。既往有高血压的妊娠史是重要的危险因素。

子痫前期是中低收入国家急性肾损伤(AKI)的常见原因,但是子痫前期患者的AKI发病率,其危险因素和肾脏预后尚不清楚。近日,心血管权威杂志Hypertension上发表了一篇研究文章,研究人员在南非子痫前期的妇女中进行了一项多中心前瞻性观察性研究。

研究人员从国家实验室数据库中提取肌酐的浓度,这些患者的最大肌酐值≥90μmol/L(≥1.02mg/dL)。肾损伤和恢复由肾脏疾病改善整体结局肌酐标准来定义。研究人员比较了各阶段AKI患者预先定义的危险因素、母亲结局和新生儿结局。

在入院接受子痫前期治疗的1547名妇女中,有237人(15.3%)符合AKI标准:第1期为6.9%(n=107),第2期为4.3%(n=67)和第3期为4.1%(n=63)。与没有AKI的女性相比,AKI妇女的孕产妇死亡(n=7;相对风险为4.3;95%CI为1.6–11.4)和死胎(n=80;相对风险为2.2;95%CI为1.8–2.8)风险更高 。围产期死亡率也有所增加(240人中有89人;37.1%)。先前妊娠的高血压是2或3期AKI最强预测因子(几率为2.24;95%CI为1.21–4.17)。肾脏恢复率随着AKI阶段的增加而降低。三分之一的幸存妇女(230名中的76名[33.0%])出院时未恢复至基线肾功能。这些妇女中约有一半(76名中的39名;51.3%)出院后不再进行肌酐检测。

总之,子痫前期在女性中很常见,并且相关的母婴死亡率很高。只有三分之二的妇女已确认肾脏恢复。既往有高血压的妊娠史是重要的危险因素。

Hypertension:伪基因HK2P1失调,或许可作为HK2的竞争性内源RNA,通过损害蜕膜化促进子娴前期的发生

子娴前期是一种孕期特有的高血压病,严重影响孕妇和胎儿的健康。但其致病原因和发病机制尚不明确。目前认为蜕膜化缺陷与子痫前期相关。越来越多的证据表明长链非编码RNA与多种疾病相关,包括子痫前期。在本研究中,研究人员通过对重症子娴前期患者和正常对照的蜕膜进行RNA序列分析发现长链非编码RNA HK2P1(己糖激酶2伪基因1)及其同源基因HK2(己糖激酶2)在子娴前期患者的蜕膜中表达。此外,研究人员对HK

重度的子痫前期(PEC)患者会伴有严重的高血压和器官功能障碍,会增加短期的心血管不良事件风险。本研究的目的旨在评估PEC孕妇短期内的超声心动图、临床特征和实验室检查的变化,主要包括右室收缩压(RVSP)和心超相关的舒张期、收缩期和斑点追踪参数。本研究纳入分析了63名PEC孕妇和36名正常妊娠孕妇。分析结果显示,与对照组相比,PEC孕妇的RVSP更高(31.0 ± 7.9 mm Hg vs. 22.

高龄孕产妇子痫前期的特点与处理难点

摘要随着“二孩政策”的全面放开,高龄孕产妇人数急剧上升,产科面临巨大挑战。高龄妊娠并发子痫前期患者病情复杂且严重,孕产妇不良妊娠结局明显增加。本文就高龄妊娠子痫前期的特点及处理难点进行讨论。国内将孕妇预产期时的年龄≥35岁定义为高龄孕妇,属高危产科范畴[1]。与全球性生育年龄推迟具有一致性,中国作为新兴经济体国家的代表,育龄妇女的平均生育年龄也在推迟,≥35岁的生育率由1998年的7.37%上

Hypertension:妊娠期尿醛固酮水平可预测胎儿出生体重

正常妊娠时,随着肾素和血管紧张素II的增加,血浆中盐皮质激素醛固酮增多,在生理血浆体积膨胀中起着重要作用。在小鼠中,醛固酮通过促进胎盘生长因子(PlGF)表达和滋养细胞增殖,促进胎儿发育。子痫前期时,同时发生醛固酮抑制与胎盘发育障碍。Anna Birukov等人推测醛固酮对人类胎盘和胎儿出生体重有独立的影响,而高钠和低钾的饮食会负性影响这种关系。为了验证上述推测,研究人员对以丹麦人群为基础的一个队

Hypertension:Toll样受体9(TLR9)可通过差异性调控VEGFA和sFLT1的表达抑制子娴前期患者母胎界面的血管生成

子娴前期是一种常见的妊娠特异性疾病,特点是血压升高和蛋白尿。母体免疫系统激活和胎盘血管生成受损被认为是导致子娴前期的致病原因。TLR9(Toll样受体9)在固有免疫中发挥作用,保护组织不受感染。本研究对TLR9在子娴前期的情况下,是否会抑制母胎界面的血管生成进行研究。实验发现子娴前期患者的胎盘中VEGFA(血管内皮生长因子A)表达下调、TLR9和sFLT1(可溶性血管内皮生长因子受体1)表达上调。
