Insights

Hepatitis B virus (HBV) infection is a leading cause of liver cancer (HCC). Non-invasive tests show promise for detecting liver fibrosis, but further research is needed to accurately predict HCC risk.

Area of Science:

  • Hepatology
  • Virology
  • Oncology

Background:

  • Chronic hepatitis B virus (HBV) infection causes a significant proportion of global hepatocellular carcinoma (HCC).
  • Unlike hepatitis C virus (HCV)-related HCC, HBV-related HCC can occur in patients without cirrhosis.
  • Limited data exist on non-invasive fibrosis tests for HBV patients.

Purpose of the Study:

  • To evaluate the performance of non-invasive tests for liver fibrosis in HBV patients.
  • To compare different non-invasive fibrosis tests and algorithms.
  • To investigate factors influencing liver stiffness measurements and their accuracy in predicting fibrosis.

Main Methods:

  • Comparison of FibroTest, Forns index, APRI, GUCI, and Hui model for fibrosis detection.
  • Evaluation of an algorithm combining APRI, FibroTest, and biopsy.
  • Assessment of liver stiffness measurement (LSM) and its correlation with fibrosis stages.
  • Analysis of factors affecting LSM, including necroinflammation and antiviral therapy.

Main Results:

  • FibroTest may outperform other serum markers in detecting significant fibrosis or cirrhosis.
  • An algorithm using APRI, FibroTest, and biopsy demonstrated high accuracy.
  • Liver stiffness correlates with fibrosis but can be affected by necroinflammatory activity and treatment.

Conclusions:

  • Non-invasive tests show potential for assessing liver fibrosis in HBV infection.
  • Further studies are required to validate LSM and serum markers in diverse clinical settings.
  • Predicting HBV-related HCC risk may benefit from algorithms incorporating demographic, viral, and fibrosis factors.

Cirrhosis II: Pathophysiology01:24

Cirrhosis II: Pathophysiology

Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
Cirrhosis I: Introduction01:23

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

Hepatitis

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. The...
Liver Regeneration01:24

Liver Regeneration

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 large...
Viral Hepatitis I: Introduction01:28

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
Chronic Pancreatitis II: Pathophysiology01:21

Chronic Pancreatitis II: Pathophysiology

Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...
