Summary
This study investigated cell-mediated immunity in liver disease patients, finding significant reactivity to liver antigens. This immune response was confirmed and linked to the sicca syndrome, suggesting a role for cellular immunity in these conditions.
Area of Science:
- Immunology
- Hepatology
- Autoimmune Diseases
Background:
- Cell-mediated immunity plays a crucial role in various pathological conditions.
- Chronic active hepatitis and primary biliary cirrhosis are autoimmune liver diseases with complex immune system involvement.
- The sicca syndrome is frequently observed in patients with chronic liver diseases.
Purpose of the Study:
- To investigate cell-mediated immunity against liver antigens in patients with chronic active hepatitis or primary biliary cirrhosis.
- To explore the correlation between cell-mediated immunity and auto-antibodies in these patients.
- To assess cell-mediated immunity to parotid extract and its association with the sicca syndrome.
Main Methods:
- Leukocyte migration test was employed to assess cell-mediated immunity in 32 patients.
- Lymphocyte blast transformation was used to confirm cell-mediated reactivity in a subset of patients.
- Serological tests were performed to detect auto-antibodies and assess for the sicca syndrome.
Main Results:
- Seventy-five percent (26/32) of patients exhibited reactivity to liver extract, indicating cell-mediated immune response.
- At least two distinct liver antigens appear to be involved in this immune response.
- Cell-mediated immunity to parotid extract was observed in 28% (10/32) of patients, correlating with the sicca syndrome.
Conclusions:
- Cell-mediated immunity is a significant factor in chronic active hepatitis and primary biliary cirrhosis.
- The immune response to liver antigens is distinct from the presence of auto-antibodies.
- Cell-mediated immunity to parotid antigens may contribute to the development of the sicca syndrome in liver disease patients.

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.

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...
