概括
在非肝硬化门高血压 (NCPH) 中,肝脑病变 (HE) 是常见的,通常与氨和分流的升高有关. 早期诊断和乳糖治疗是改善患者治疗结果的关键.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 胃肠病学 胃肠病学
- 血管医学 血管医学
背景情况:
- 肝性脑病变 (HE) 通常与肝硬化有关,但其在非肝硬化门性高血压 (NCPH) 中的发生程度不太清楚.
- 像肝外门静脉阻塞 (EHPVO) 这样的NCPH条件提供了无严重肝损伤的HE机制的见解.
研究的目的:
- 审查NCPH患者的HE频谱和管理.
- 突出NCPH中HE的患病率和风险因素,重点关注港口系统的分流和氨水平.
主要方法:
- 综合了NCPH中HE发生和管理研究的数据,包括EHPVO,异常性NCPH (INCPH) 和波尔托鼻状血管疾病 (PSVD).
- 分析了最小肝脑病变 (MHE) 的患病率和与MHE和自发冲刺相关的静脉氨水平.
主要成果:
- 在NCPH中,MHE的患病率在12%至60%之间,近三分之一的EHPVO患者受到影响.
- 在MHE患者中观察到高静脉氨水平,这些患者有自发的分流.
- 大型港口系统的分流系统显著增加了HE风险,在46-71%的复发性HE病例中存在.
结论:
- 在NCPH中,特别是EHPVO中,HE的特点是氨量高和自发的冲动.
- 尽管它很普遍,但NCPH中的HE经常被忽视;通过查工具及时诊断至关重要.

Hepatic Portal System
908
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...

Esophageal Varices-I: Introduction
71
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Hepatic Drug Excretion: Enterohepatic Cycling
964
Enterohepatic cycling involves the active secretion of drugs and their metabolites into the bile via transporters in the canalicular membrane of hepatocytes. This secretion is an integral part of the digestive process, releasing these substances into the gastrointestinal (GI) tract.
Post-release drugs and metabolites can be reabsorbed into the body from the intestine. For conjugated metabolites like glucuronides, reabsorption requires enzymatic hydrolysis by intestinal microflora. This...

Diseases of the Liver and Gallbladder
421
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...

Esophageal Varices-II: Clinical Features and Management
46
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
