Summary
Hepatitis B virus (HBV) is a key cause of chronic liver disease in India. Viral replication markers correlate with liver injury severity, suggesting ongoing HBV multiplication drives disease progression.
Area of Science:
- Hepatology
- Virology
- Gastroenterology
Background:
- Chronic liver diseases (CLD) pose a significant health burden globally.
- Hepatitis B virus (HBV) is a major etiological agent for CLD, particularly in endemic regions.
- Understanding HBV replication dynamics is crucial for managing CLD.
Purpose of the Study:
- To investigate the role of Hepatitis B virus (HBV) in chronic liver diseases in India.
- To assess HBV replication markers and their correlation with disease severity.
- To determine the etiological significance of HBV in the Indian population.
Main Methods:
- Study included 175 subjects with chronic liver diseases: chronic active hepatitis, liver cirrhosis, and asymptomatic HBV carriers.
- Hepatitis B virus (HBV) DNA-polymerase activity and HBe-markers were assessed.
- Analysis of viral markers in relation to HBsAg status and patient demographics.
Main Results:
- HBV DNA-polymerase activity and HBeAg were detected in a significant proportion of patients across all CLD groups.
- Higher positivity rates for viral replication markers were observed in liver cirrhosis patients.
- HBV multiplication was evident even in the absence of HBsAg, and markers correlated with disease severity and decreased with age.
Conclusions:
- Hepatitis B virus (HBV) is the predominant etiological factor for chronic liver diseases in India.
- Horizontal transmission is the likely route of HBV infection in young adults.
- Continued HBV replication is implicated in the progression of chronic liver injury and disease.
