J Thromb Haemost:产前XIII因子活性对产后失血量的影响

2020-03-17 MedSci原创 MedSci原创

迄今为止,在分析产前凝血因子对PPH影响的最大的人群中,产前凝血因子XIII活性对每个统计模型和临床亚组的产后失血量都有明显的影响。研究人员的假设是,早期补充XIII因子可能成为预防和有效早期治疗PP

产后出血(PPH)是孕产妇死亡的主要原因之一,已知的危险因素有多种,但经常发生意外。全世界PPH发病率和相关的孕产妇发病率和死亡率都在上升。近日,血栓和凝血疾病权威杂志Journal of Thrombosis and Haemostasis上发表了一篇研究文章,该研究旨在评价产前凝血参数对产后失血量的影响。

这项单中心前瞻性队列研究分析了1300名妇女产前凝血因子II、XIII和纤维蛋白原的水平。在临产时采集血样,并在最后一名患者分娩后进行分析,以确保避免潜在的治疗偏差。失血量通过一个经验证的方法进行量化。研究人员采用连续结局logistic回归分析凝血因子对失血量的影响。

产前凝血因子XIII活性对测量的失血量产生明显的影响:产前凝血因子XIII每增加一个单位(%),其风险比为1.011(95%置信区间为1.006~1.015;P<0.001)。作为例证,这表明凝血因子XIII活性增加30%,PPH(定义为失血≥500ml)不发生的几率增加38.9%。在对分娩方式进行分层后,校正其他危险因素,这种效应仍然显著,且与所用的统计模型无关。II因子而非纤维蛋白原具有部分类似的作用,但效应不明显。

迄今为止,在分析产前凝血因子对PPH影响的最大的人群中,产前凝血因子XIII活性对每个统计模型和临床亚组的产后失血量都有明显的影响。研究人员的假设是,早期补充XIII因子可能成为预防和有效早期治疗PPH的新工具,这一假设应该在未来的试验中进行评估。
