[Chronic hepatitis B: diagnostic value of hepatitis-B-virus DNA analysis in serum and liver tissue]
Insights
Serological markers are sufficient for diagnosing hepatitis B virus (HBV) infection. However, detecting HBV DNA in serum or liver tissue is crucial for guiding antiviral therapy decisions in chronic liver disease patients.
Area of Science:
- Hepatology
- Virology
- Molecular Diagnostics
Context:
- Chronic liver disease diagnosis and management.
- Assessing hepatitis B virus (HBV) infection.
- Evaluating diagnostic methods for viral DNA detection.
Purpose:
- To investigate the diagnostic value of hybridization analyses for HBV DNA detection.
- To determine the correlation between HBV DNA presence and clinical/histological disease.
- To assess the utility of HBV DNA detection in guiding antiviral therapy.
Summary:
- Hybridization analyses detected HBV DNA in serum and liver tissue of chronic liver disease patients.
- HBV DNA was detected even without HBeAg, indicating active viral replication.
- No correlation was found between HBV DNA and clinico-chemical or histological disease severity.
- Serological markers were deemed sufficient for HBV infection diagnosis.
- HBV DNA detection is vital for selecting patients for and monitoring antiviral therapy efficacy.
Impact:
- Highlights the sufficiency of serological markers for routine HBV diagnosis.
- Emphasizes the critical role of HBV DNA detection in personalized antiviral treatment strategies.
- Provides insights into managing chronic liver disease patients with HBV infection.
Abstract:
The diagnostic value of hybridization analyses for the detection of hepatitis B virus (HBV) DNA in serum and liver tissue was investigated in 79 patients with chronic liver disease. Active viral replication was demonstrated by the detection of HBeAg or HBV-DNA in serum or liver tissue. However, HBV-DNA was also detected in the absence of HBeAg in serum. No correlation was found between the presence of HBV-DNA in serum or liver tissue and clinico-chemical or histological disease. In HBsAg-negative patients no HBV-DNA was detected in serum or liver tissue. These data indicate that serological markers are sufficient for the diagnosis of HBV infection. However, detection of HBV-DNA in serum or active viral replication in liver tissue is important in selecting patients for antiviral therapy (e.g. interferon) and monitoring its efficacy.
