To investigate the dynamics and clinical significance of serum hepatitis B virus (HBV) DNA levels during the terminal phase of acute-on-chronic liver failure (ACLF) with different hepatitis B e antigen (HBeAg) status.
One-hundred-and-seven patients with terminal ACLF were tested for HBeAg status by electrochemiluminescence immunoassay and serum HBV DNA levels by real-time PCR at three chronological time ranges, representing increasing severity of disease phases prior to death (day 0): 29-56 d, 15-28 d, and 0-14 d.
In the 37 HBeAg(+) patients, HBV DNA levels at above-mentioned phases were 6.10+/-1.63, 5.61+/-1.50, and 5.29+/-1.96 log10 copies/mL. In the 70 anti-HBe(+) patients, HBV DNA levels were 4.63+/-1.82, 5.81+/-1.78, and 4.93+/-1.73 log10 copies/mL. Phase to phase comparisons revealed that the HBV DNA level in the HBeAg(+) group was significantly higher than that in the anti-HBe(+) group at 29-56 d (P less than 0.05), and that 15-28 d and 0-14 d were not significantly different (P more than 0.05). Intragroup comparisons of phases revealed no significant differences in the HBeAg(+) group (P more than 0.05), but a significant difference between 15-28 d and 0-14 d (P less than 0.05) for the anti-HBe(+) group.
Serum levels of HBV DNA in patients with HBeAg positivity are higher than those in patients with anti-HBe positivity as the disease phase of ACLF nears fatality. Following the deterioration to liver failure, the HBV DNA load in HBeAg(+) patients remains stable while that in anti-HBe(+) patients decreases.
