概括
计算机断层扫描 (CT) 输液显示在自身免疫性肝炎 (AIH) 中动脉流量增加 (AF) 和门流量减少 (PF). 这些血液动力学变化,即使在早期纤维化中也很明显,可以作为AIH肝损伤的非侵入性标志物.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 计算机断层扫描 (CT) 输液是一种评估肝脏血液动力学的非侵入性方法.
- 与病毒性肝炎相比,在自身免疫性肝炎 (AIH) 中CT输液的证据有限.
- 与AIH相关的肝损伤可能导致显著的血液动力学变化.
研究的目的:
- 在与AIH相关的纤维化和肝硬化患者和健康对照患者中比较CT输液参数 (动脉流量[AF],门流量[PF],输液指数[PI]).
- 评估CT输液参数作为AIH严重程度的非侵入性标记物的潜力.
主要方法:
- 一个单一中心前性研究包括21名AIH纤维化患者,17名AIH肝硬化患者,20名健康的肝脏捐赠者.
- 对所有参与者的CT perfusion参数 (AF,PF,PI) 进行了计算.
- 进行了组织学分期 (F1-F4) 和炎症活性分级 (A1-A4).
主要成果:
- 与对照组相比,在AIH纤维化和AIH肝硬化组中,动脉流量 (AF) 显著增加 (p<0.001).
- 与对照组相比,在AIH纤维化和AIH肝硬化组中,门户流量 (PF) 显著降低 (p<0.001).
- AF和PF在区分AIH患者与对照患者方面表现出95%的灵敏度,纤维化和肝硬化阶段之间没有显著差异.
结论:
- 增加的AF和减少的PF即使在AIH的纤维化阶段也可以检测到.
- 这些血液动力学变化可以作为评估AIH相关肝损伤的严重程度的有价值的非侵入性生物标志物.

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test
210
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...

Autoimmune Disorders
1.9K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment
281
Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Hepatic Portal System
6.4K
The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...
