概括
患有阿拉吉尔综合征 (ALGS) 的儿童的血清胆汁酸 (SBA) 水平较低,预测更好的肝病结果,包括本地肝存活率 (NLS) 和无事件存活率 (EFS). 这些发现表明,减少SBA可能会改善ALGS患者的临床结果.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 儿科胃肠病学 儿科胃肠病学
- 罕见疾病 罕见疾病
背景情况:
- 阿拉吉尔综合征 (ALGS) 是一种遗传性疾病,导致肝病和其他健康问题.
- 血清胆汁酸 (SBA) 水平是胆固醇性肝脏疾病的关键指标.
- 新兴的疗法准叶胆酸载体 (IBAT),以降低SBA.
研究的目的:
- 调查SBA水平是否预测ALGS儿童的肝病结果.
- 评估SBA的预后价值与本地肝存活率 (NLS) 和无事件存活率 (EFS) 相比.
主要方法:
- 利用了来自全球ALagille联盟 (GALA) 队列的数据.
- 采用考克斯回归分析与SBA的时间依赖共变量.
- 评估了102μmol/L的预后SBA值,并对总 bilirubin (TB) 进行调整.
主要成果:
- 在SBA和TB之间观察到中度正相关性 (r=0.47,p<0.001).
- 低于102μmol/L的SBA水平显著预测了NLS和EFS的改善 (p<0.001).
- 低SBA仍然是改善EFS的重要预测因素,即使在对1年结核病清除进行调整后也是如此.
结论:
- 在ALGS患者中减少SBA与更好的NLS和EFS有关.
- 在ALGS患者中,SBA还与ALGS患者与NLS相关,这些患者获得了无菌胆固醇症.
- 降低SBA可能是改善ALGS临床结果的治疗策略.

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test
170
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...

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow
204
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...
