Insights
Hepatitis B virus (HBV) DNA and preS1 antigen levels correlate with viral replication in chronic hepatitis B patients. PreS1 antigen aids in assessing viral status, especially when HBV DNA detection is challenging.
Area of Science:
- Hepatology
- Virology
- Immunology
Context:
- Chronic hepatitis B (CHB) is a significant global health concern.
- Accurate monitoring of viral replication is crucial for managing CHB.
- Hepatitis B virus (HBV) serum markers, including preS1 antigen and HBV DNA, are key indicators.
Purpose:
- To investigate the correlations between preS1 antigen, HBV DNA, and other HBV serum markers in CHB patients.
- To evaluate the utility of preS1 antigen as a diagnostic and monitoring tool in CHB.
Summary:
- This study analyzed 1158 CHB patients, measuring HBV markers, preS1 antigen, and HBV DNA.
- HBV DNA positivity (68.9%) was higher than preS1 antigen positivity (54.8%). Both were higher in HBeAg-positive patients.
- PreS1 antigen showed higher sensitivity but lower specificity than HBeAg, with detection rates increasing with HBV DNA levels.
Impact:
- PreS1 antigen can serve as an auxiliary marker for viral replication assessment in CHB.
- It is particularly useful in HBeAg-negative cases or when HBV DNA detection is not feasible.
- Findings can aid in optimizing therapeutic strategies and monitoring treatment efficacy in CHB.
Objective:
To study the correlations between preS1 antigen, HBV-DNA and hepatitis B virus (HBV) serum markers in patients with chronic hepatitis B.
Methods:
The HBV markers, preS1 antigen and HBV-DNA were determined using enzyme- linked immunosorbent assay and quantitative PCR in 1158 patients with chronic hepatitis B.
Results:
In these patients, the HBV-DNA positivity rate was 68.9%, significantly higher than preS1 antigen positivity (54.8%, chi2=53.24, P<0.005). The positivity rates of both HBV-DNA and PreS1-antigen were significantly higher in HBeAg-positive patients than in HBeAg-negative patients (P<0.005). The coincident rates of preS1-antigen and HBeAg with HBV-DNA were 56.9% and 63.3%, respectively. PreS1 antigen had higher sensitivity but lower specificity than HBeAg. The detection rates of preS1 antigen and HBeAg increased with the level of HBV-DNA, and preS1 antigen positivity was higher than that of HBeAg in patients with low HBV-DNA levels.
Conclusion:
Detection of HBV serum markers along with preS1 antigen and HBV-DNA may help assess the status of viral replication and therapeutic efficacy in patients with chronic hepatitis B. PreS1 antigen may serve as an auxiliary indicator in HBeAg-negative cases or when HBV-DNA detection is impossible.
