Summary
Subcutaneous adipose tissue index (SATI) and myosteatosis are key predictors of overt hepatic encephalopathy (OHE) after transjugular intrahepatic portosystemic shunt (TIPS) procedures. An integrated score combining these factors offers superior predictive accuracy for post-TIPS OHE.
Area of Science:
- Hepatology
- Gastroenterology
- Medical Imaging
Background:
- Overt hepatic encephalopathy (OHE) is a complication after transjugular intrahepatic portosystemic shunt (TIPS) procedures.
- The role of body composition in predicting OHE post-TIPS requires further investigation.
Purpose of the Study:
- To identify body composition factors associated with OHE risk after TIPS.
- To develop and validate a predictive score for post-TIPS OHE.
Main Methods:
- Analysis of body composition (skeletal muscle, adipose tissue indices, sarcopenia, myosteatosis) in 571 patients undergoing TIPS.
- Logistic regression to identify independent risk factors for OHE.
- Development of an integrated predictive score using stepwise regression and Akaike information criterion (AIC).
Main Results:
- Skeletal muscle indices and sarcopenia showed limited association with post-TIPS OHE.
- Subcutaneous adipose tissue index (SATI) and myosteatosis were identified as independent risk factors for OHE.
- An integrated score (Score ALL) incorporating SATI and myosteatosis demonstrated superior predictive performance (AIC: 655.28) compared to individual factors.
Conclusions:
- SATI and myosteatosis are significant predictors of OHE following TIPS.
- The developed integrated score offers a more accurate prediction of post-TIPS OHE compared to other body composition measures.

01:21Hepatic Portal System

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...

01:16Hepatic Drug Excretion: Influencing Factors
127
The biliary system of the liver, crucial for bile secretion and drug excretion, comprises intrahepatic bile ducts that merge to form the common hepatic duct. This duct, carrying hepatic bile, combines with the cystic duct, draining the gallbladder and forming the common bile duct, which empties into the duodenum. Bile, produced by hepatic cells lining the bile canaliculi, is composed primarily of water, bile salts, pigments, electrolytes, and lesser amounts of cholesterol and fatty acids. Bile...

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...

01:09Hepatic Drug Clearance: Effect of Protein Binding
194
Hepatic clearance is influenced by protein binding based on the drug's extraction ratio. Drugs with high extraction ratios are considered flow-limited and remain unaffected by protein binding during hepatic clearance. On the other hand, drugs with low extraction ratios may be impacted by plasma protein binding, although the extent of this influence depends on the fraction of the drug bound.
For low-extraction-ratio drugs that are less than 80% protein-bound, minor changes in protein binding...

The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is...

01:14Hepatic Drug Clearance: Role of Transporters
54
In the liver and bile canaliculi, influx and efflux transporters modification can influence intrinsic clearance. Transporters play a significant role in moving drugs within liver cells. Elaborate models, such as the Biopharmaceutical Classification System (BCS), are essential to relate transporters to drug disposition. This system categorizes drugs into four classes based on solubility and permeability, providing insights into elimination routes and the effects of transporters following oral...
