Insights
In HBeAg-negative chronic hepatitis B (CHB), higher serum HBV DNA levels correlate with elevated ALT, aiding treatment decisions. This study confirms a significant link between HBV DNA and ALT in these patients.
Area of Science:
- Hepatology
- Virology
- Biochemistry
Context:
- HBeAg-negative chronic hepatitis B (CHB) presents a challenge due to undefined treatment thresholds.
- Accurate assessment of viral load and liver inflammation is crucial for managing CHB.
Purpose:
- To evaluate serum HBV DNA and transaminase levels in HBeAg-negative CHB patients.
- To investigate the correlation between HBV DNA and ALT levels in this cohort.
Summary:
- Serum HBV DNA levels were significantly higher in HBeAg-negative CHB patients with elevated ALT (>/= 2X UNL) compared to those with lower ALT (< 2X UNL).
- A significant positive correlation (r=0.416, p<0.001) was observed between serum ALT and HBV DNA levels.
- HBV DNA levels did not significantly differ between patients with and without cirrhosis.
Impact:
- Findings suggest that serum ALT levels can serve as a surrogate marker for HBV DNA levels in HBeAg-negative CHB.
- This correlation may assist clinicians in making more informed treatment decisions for HBeAg-negative CHB patients.
Background/Aims:
HBeAg-negative chronic hepatitis B (CHB) has a poor long-term prognosis. Since no precise clinically relevant HBV thresholds are known in HBeAg-negative CHB, the decision to treat is difficult. The aim of this study was to evaluate the levels of serum HBV DNA and transaminase and to investigate the correlation of these values in patients with HBeAg-negative CHB.
Methods:
The study analyzed the sera from 82 patients with HBeAg-negative CHB, 61 men and 21 women. The mean age was 45 years. The patients were divided into two groups according to serum ALT levels: the patients with lower ALT level (n=52, UNL < ALT < 2 X UNL) and higher level (n=30, ALT >/= 2 X UNL). The level of serum HBV DNA was determined by the Cobas Amplicor HBV Monitor(TM) (Roche).
Results:
The median serum HBV DNA level was 2.7 X 10(5) copies/mL in patients with HBeAg-negative CHB. The median serum HBV DNA level of patients with a higher ALT level (1.0 X 10(6) copies/mL) was significantly higher than that of patients with a lower ALT level (5.6 X 10(4) copies/mL)(p<0.001). The serum ALT level was correlated with serum HBV DNA levels in patients with HBeAg-negative CHB (r=0.416, p<0.001). The serum level of HBV DNA in patients with cirrhosis (median 2.0 X 10(5) copies/mL) did not differ from patients without cirrhosis (median 4.7 X 10(5) copies/mL).
Conclusions:
The level of serum HBV DNA was higher in patients with higher serum ALT level than it was in patients with lower serum ALT, and it was closely correlated with serum ALT levels in HBeAg-negative CHB.
