Hepatitis01:25

Hepatitis

42
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver.

Diseases of the Liver and Gallbladder

2.3K
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: Pathophysiologic Assessment and Liver Function Test

257
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 Regeneration01:24

Liver Regeneration

5.0K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Liver Histology01:27

Liver Histology

10.6K
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...

Area of Science:

  • Hepatology
  • Virology
  • Metabolic Diseases

Background:

  • Hepatitis C virus (HCV) infection frequently results in chronic liver disease, affecting 75-80% of individuals.
  • Chronic HCV can progress to steatosis (fatty liver), cirrhosis, and hepatocellular carcinoma.
  • Steatosis occurs in 55% of HCV patients due to viral and host factors like obesity and insulin resistance.

Purpose of the Study:

  • To examine the interrelationship between Hepatitis C virus (HCV), steatosis, and metabolic syndrome.
  • To discuss the implications of these conditions on treatment efficacy and disease progression.

Main Methods:

  • Review of existing literature on HCV, steatosis, and metabolic syndrome.
  • Analysis of viral and host factors contributing to steatosis in HCV patients.

Main Results:

  • HCV infection contributes to steatosis through viral proteins and host factors such as overweight and insulin resistance.
  • Standard treatments for chronic HCV (pegylated interferon and ribavirin) show low response rates (≤40%).
  • While direct-acting antivirals improve response rates, HCV-related end-stage liver disease remains a leading cause for liver transplantation.

Conclusions:

  • The interplay between HCV, steatosis, and metabolic syndrome is critical for understanding disease progression and treatment challenges.
  • Further research is needed to optimize therapeutic strategies for HCV patients with co-existing metabolic abnormalities.
