Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test01:22

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

169
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...

Diseases of the Liver and Gallbladder

1.8K
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...

Liver Histology01:27

Liver Histology

4.0K
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...

Hepatic Portal System01:21

Hepatic Portal System

5.1K
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...

Bile01:19

Bile

3.7K
Bile is a crucial bodily fluid, characterized by its yellow-green color and alkaline nature. Produced in the liver, it is transported through the common hepatic duct into either the cystic duct, leading to the gallbladder, or directly into the common bile duct. The flow of bile is regulated by the sphincter of Oddi located at the entrance of the duodenum. When this sphincter is closed, bile is redirected to the gallbladder for storage and concentration.
Bile is released when dietary fats enter...

Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

2.5K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Summary

Recent pathology studies highlight key features of viral hepatitis C and E, nonalcoholic steatohepatitis, and immunoglobulin G4-associated cholangitis, advancing understanding of liver and biliary diseases.

Area of Science:

  • Hepatology
  • Gastroenterology
  • Pathology

Background:

  • Histopathology of liver and biliary diseases provides crucial insights into disease mechanisms.
  • Understanding pathogenesis aids in diagnosing and managing complex hepatic and biliary conditions.

Purpose of the Study:

  • To review recent studies on the histopathology and pathogenesis of liver and biliary diseases.
  • To summarize key findings in viral hepatitis, nonalcoholic steatohepatitis, and related disorders.

Main Methods:

  • Review of peer-reviewed literature from the past year.
  • Analysis of histopathological findings in various liver and biliary conditions.
  • Integration of genetic and immunohistochemical data.

Main Results:

  • Hepatitis E shows distinct portal and periportal inflammation patterns.
  • Hepatitis C virus replication in hepatocytes was observed.
  • Ductular reaction in nonalcoholic steatohepatitis correlates with fibrosis and senescence.
  • Hepcidin's role in iron homeostasis and hemochromatosis was detailed.
  • Liver-cell adenomas can be subtyped using morphology and genetic analysis.
  • Immunoglobulin G4-associated cholangitis shares features with primary sclerosing cholangitis.

Conclusions:

  • Pathologic features of viral hepatitis C and E are significant.
  • Immunohistochemistry is vital for diagnosing ductular reactions and liver tumors.
  • Systemic disorders impacting the biliary system require further study.
