概括
患有单心室心脏病 (SVHD) 的儿童在Fontan手术前后表现出改变的阿尔金因代谢. 较低的阿基宁代谢物比率与更长的住院时间和手术后并发症增加有关.
科学领域:
- 儿童心脏病学 儿童心脏病学
- 代谢学 代谢学 代谢学
- 血管生物学 血管生物学
背景情况:
- 单心室心脏病 (SVHD) 患者在格伦息后表现出氨酸/氧化 (NO) 途径功能障碍.
- 在SVHD中,在Fontan手术 (3期) 后,阿基尼因失调的持续性尚不清楚.
研究的目的:
- 在接受Fontan治疗SVHD的儿童中量化循环中的阿金宁代谢物.
- 评估阿金宁代谢物度与术后结果之间的关联.
主要方法:
- 前性队列研究包括82名接受Fontan手术的儿童和49名健康对照.
- 在手术前和手术后测量了循环中的阿金宁代谢物,使用双重质谱法.
- 评估的结果包括停留时间 (LOS) 和肺部排水.
主要成果:
- 在手术前,SVHD患者的氨酸,氨酸酸盐,氨酸和NMMA含量较低,与对照组相比,氨酸和氨酸代谢物比例较高,氨酸代谢物比例较低.
- 在术后,与手术前相比,患者表现出降低氨酸和增加氨酸/ADMA,氨酸/氨酸和氨酸/氨酸的比率.
- 术后较低的氨酸和较低的氨酸/ADMA和氨酸/氨酸的比率与较长的LOS和增加的多叶液排水相关.
结论:
- 在SVHD的儿童中,在第三阶段息之前和之后,素代谢发生了显著的变化.
- 手术后的代谢障碍,特别是较低的氨酸/ADMA和氨酸/氨酸比率,与患者患病率的增加有关.
- 氨酸路径的改变可能是Fontan手术后SVHD患者不良结果的可修改风险因素.
