Insights

Histopathological evaluation in children with chronic hepatitis B (CHB) shows varying liver injury severity. Necroinflammatory activity correlates with fibrosis, and viral antigen expression confirms disease etiology.

Area of Science:

  • Hepatology
  • Pediatric Gastroenterology
  • Virology

Background:

  • Histopathological liver evaluation is crucial for diagnosing liver diseases.
  • Chronic hepatitis B (CHB) in children requires careful assessment of disease progression.

Purpose of the Study:

  • To evaluate liver inflammatory activity and fibrosis in pediatric CHB patients.
  • To correlate these histological findings with viral antigen expression (HBsAg, HBcAg) before treatment.

Main Methods:

  • Analysis of 190 liver biopsies from children with CHB using the modified Knodell system.
  • Immunomorphological analysis for HBsAg and HBcAg in 125 biopsies.

Main Results:

  • Mild to moderate necroinflammatory activity and mild to advanced fibrosis were observed.
  • A significant correlation was found between necroinflammation grading and fibrosis staging.
  • HBsAg was detected in 62 biopsies; HBcAg was found in 108 biopsies, with partial correlation to inflammatory infiltrate.

Conclusions:

  • Liver injury in pediatric CHB is variable, with correlated necroinflammation and fibrosis.
  • Viral antigen expression confirms CHB etiology but shows limited correlation with specific histological changes.

Liver Histology

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...

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...

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: 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...
