Hepatitis

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...

Viral Hepatitis I: Introduction

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...

Cytomegalovirus Disease

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Liver Histology

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...

Cirrhosis I: Introduction

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...

Summary

Hepatitis B (HB) infection in liver allografts typically mirrors non-allografts, but fibrosing cholestatic hepatitis (FCH) can mimic rejection. Immunohistochemical stains confirm Hepatitis B virus (HBV) and help differentiate causes of liver injury.

Area of Science:

Hepatology
Transplant Pathology
Virology

Background:

Hepatitis B (HB) infection in liver allografts presents histopathologically similar to non-allografts.
A subset of patients develop fibrosing cholestatic hepatitis (FCH), an atypical HB pattern mimicking acute or chronic rejection.

Purpose of the Study:

To delineate the histopathologic features of Hepatitis B virus (HBV) infection in liver allografts.
To differentiate HBV-related liver injury from other causes of hepatitis post-transplantation.

Main Methods:

Histopathologic examination of liver allografts.
Immunohistochemical staining for hepatitis B surface antigen (HBsAg) and hepatitis B core antigen (HBcAg).

Main Results:

The expression patterns of HBsAg and HBcAg aid in determining the primary cause of liver injury.
FCH presents as a severe cholestatic syndrome, potentially confused with rejection.

Conclusions:

Histopathology of HB in liver allografts is generally similar to non-allografts, with FCH being a distinct entity.
Immunohistochemistry is crucial for confirming HBV infection and assessing its contribution to liver injury.
Clinical correlation is essential for accurate diagnosis in complex liver transplant pathology.
