概括
在患有Fontan循环 (FC) 的成年人中,胆酸清除受损,这是一种与复杂的先天性心脏病相关的疾病. 更糟糕的Fontan生理学与更高的分流百分比相关,这表明血液动力学问题有助于肝病的进展.
科学领域:
- 心脏病学 心脏病学
- 肝病学 肝病学是一种肝病学.
- 儿童心脏病学 儿童心脏病学
背景情况:
- 复杂的先天性心脏病中的Fontan循环 (FC) 呈现出改变的血液动力学,并与Fontan相关的肝病有关.
- 在FC患者中异常的肝输液可能会损害胆酸盐清除.
- 这项研究调查了与健康对照组相比,患有FC的成年人中胆酸盐清除率.
研究的目的:
- 为了比较Fontan循环 (FC) 的成年人与健康对照的胆酸盐清除值.
- 探索FC患者的胆酸盐清除率和临床特征之间的关联.
- 调查血液动力学障碍在Fontan相关肝病进展中的作用.
主要方法:
- 前性队列研究 (2019-2022),包括35名患有FC的成年人和26名对照.
- 通过使用双胆酸清除试验 (HepQuant Shunt) 评估胆酸的全身和门肝清除.
- 通过回归分析计算了系统HFR/门口HFR比率 (SHUNT%) 并通过回归分析分析了与临床变量之间的关联.
主要成果:
- 与对照组相比,FC参与者表现出较低的全身和门肝过率 (HFR).
- 虽然SHUNT%是可比的,但个别的SHUNT%差异很大 (8%-76%),其中23%超过30%.
- 在FC患者中增加的SHUNT%与升高的Fontan压力,较高的肺上脉动附带流量,较低的氧气和,较高的NT-proBNP,血小板狭窄和升高的纤维化-4指数相关.
结论:
- 通过全身和门口HFR评估的胆酸清除在Fontan循环患者中显著受损.
- 在FC患者中,较高的SHUNT%与更糟糕的Fontan生理学指标有关.
- 这些发现支持了血液动力学障碍导致Fontan相关肝病进展的假设.

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow
Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug binding...
Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...
