Nuclear changes in hepatocytes of patients with non-A, non-B hepatitis
Gastroenterology
|July 1, 1981
Abstract:
Experimental non-A, non-B hepatitis infection has been shown to produce two distinct ultrastructural changes in chimpanzees: intranuclear particles and intracytoplasmic tubular structures. We report our observations of intranuclear particles in humans with acute non-A, non-B hepatitis. These particles appear to be specific for at least one type of non-A, non-B hepatitis.
Insights
Researchers observed intranuclear particles in humans with acute non-A, non-B hepatitis. These particles may be specific markers for certain types of this liver disease.
Area of Science:
- Hepatology
- Virology
- Cell Biology
Background:
- Non-A, non-B hepatitis is a significant cause of viral hepatitis.
- Previous studies in chimpanzees identified two ultrastructural changes associated with experimental non-A, non-B hepatitis: intranuclear particles and intracytoplasmic tubular structures.
Purpose of the Study:
- To investigate the presence and potential specificity of intranuclear particles in human cases of acute non-A, non-B hepatitis.
- To compare ultrastructural findings in human hepatitis with those observed in experimental animal models.
Main Methods:
- Electron microscopy was used to examine liver biopsy samples from patients with acute non-A, non-B hepatitis.
- Ultrastructural analysis focused on identifying and characterizing intranuclear particles and other cellular changes.
Main Results:
- Intranuclear particles were observed in humans with acute non-A, non-B hepatitis.
- The presence of these intranuclear particles suggests a potential role as a specific marker for at least one form of non-A, non-B hepatitis.
Conclusions:
- Intranuclear particles are a relevant ultrastructural finding in human acute non-A, non-B hepatitis.
- These particles may serve as diagnostic markers for specific types of non-A, non-B hepatitis, aiding in etiological classification.

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...

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...

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.

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...

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...

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...
