服用抗发作药物的成年患者经常表现出亚临床凝血缺陷,由维生素K缺乏引起的蛋白质 (PIVKA) 的升高表明. 这一发现支持怀孕期间服用这些药物的患者补充维生素K.
科学领域:
- 生物化学 生物化学
- 血液学 血液学 血液学
- 药理学 药理学是指药理学的学科.
背景情况:
- 由维生素K缺失引起的蛋白质 (PIVKA) 是当维生素K依赖的炭化受损时升高的前列红蛋白前体.
- 抗药物通常用于治疗.
- 以前的研究表明,妊娠期抗药物暴露与凝血异常之间存在联系.
研究的目的:
- 在接受抗治疗的成年患者中评估PIVKA水平.
- 为了确定抗药的使用是否与患者的血液凝固受损有关.
- 评估这种患者群体对维生素K补充的潜在需求.
主要方法:
- 在16名接受各种抗药的成年患者中测量了PIVKA阳性.
- 将PIVKA度与10个年龄相匹配的健康对照进行了比较.
- 统计分析包括t测试和费舍尔精确测试.
主要成果:
- 与对照组 (1.1 +/- 0.7%) 相比,患者的PIVKA平均度 (4.6 +/- 2.3%) 显著更高 (p < 0.001).
- 81%的患者显示PIVKA值高于对照范围 (p < 0.001).
- 在PIVKA水平和特定抗药物之间没有发现相关性;其他凝血指数保持正常.
结论:
- 大多数接受抗治疗的成年患者都存在亚临床凝血缺陷.
- 在这个群体中PIVKA水平升高加剧了人们对凝血问题的担忧.
- 这些发现支持在涉及抗治疗的怀孕中服用产前维生素K补充剂的建议.
