Hepatitis B antigen in liver cirrhosis and hepatocellular carcinoma
Insights
Hepatitis B virus infection was investigated in liver cirrhosis and cancer cases. While Hepatitis B antigen was found in some cirrhosis patients, its direct link to liver disease progression was not definitively established in this study.
Area of Science:
- Hepatology
- Virology
- Pathology
Background:
- Liver cirrhosis is a significant health concern, often linked to various etiological factors.
- Hepatocellular carcinoma frequently co-occurs with liver cirrhosis.
- Hepatitis B virus (HBV) is a known risk factor for liver disease.
Purpose of the Study:
- To investigate the prevalence of Hepatitis B antigen (HB-Ag) and its antibodies (HB-AB) in postmortem cases of liver cirrhosis and hepatocellular carcinoma.
- To explore potential associations between HBV infection and different types of cirrhosis.
- To examine the presence of HB-Ag in patients with hepatocellular carcinoma.
Main Methods:
- Postmortem diagnosis of liver cirrhosis in 43 cases over one year.
- Testing of blood samples from cirrhotic patients and 120 controls for HB-Ag and HB-AB using counter-electrophoresis.
- Classification of cirrhosis types based on morphology and etiological data.
Main Results:
- HB-Ag was detected in 5 out of 25 subjects with macronodular cirrhosis and in one alcoholic patient.
- One patient with liver carcinoma tested positive for HB-Ag.
- HB-Ag and HB-AB were found in only one control subject.
- Microscopic liver lesions did not show a specific relationship with HB-Ag presence in cirrhotic livers.
Conclusions:
- The study found a low prevalence of HB-Ag in liver cirrhosis and hepatocellular carcinoma cases.
- A direct correlation between HB-Ag and specific microscopic cirrhotic lesions was not evident.
- The findings suggest a limited role or coincidental nature of HBV infection in the studied postmortem cohort.
Abstract:
Postmortem diagnosis of liver cirrhosis was made over a one-year period in 43 cases, 18 of which also exhibited hepatocellular carcinoma. Blood samples taken from these and 120 other patients who died from other diseases were tested for hepatitis-B antigen (HB-Ag) and its antibodies (HB-AB) by counter-electrophoresis. The types of cirrhosis found were classified on the basis of morphological characteristics and available etiological data. The greater part of controls had had cardiovascular diseases and 32 had had non-hepatic carcinoma. Age limits were similar in the cirrhotic and control groups. HB-Ag was detected in 5 of the 25 subjects with macronodular cirrhosis and in one alcoholic patient among 18 subjects with other types of cirrhosis. The possibility of a coincidental HB virus infection existed in the alcoholic case and in one case of macronodular cirrhosis. Only one patient with liver carcinoma had HB-Ag. Among the 120 controls, HB-Ag and HB-AB were found in a one case. Microscopic lesions did not seem to be related specifically to the presence of HB-Ag in the cirrhotic livers.
