To investigate the relationship and clinical significances of HBeAg status with serum HBV DNA loads, model for end-stage liver disease (MELD) scores in patients with acute-on-chronic hepatitis B liver failure during terminal phase.
120 fatal patients were enrolled. At three phases of 0 -14 d, 15-28 d and 29-90 d before death, they were detected serum HBeAg, HBV DNA loads order meanwhile MELD scores were calculated.
In 51 patients with HBeAg positive, HBV DNA levels were (5.25 +/- 1.99), (5.45 +/- 1.47) and (6.06 +/- 1.77) log10 copies/ml while MELD scores were (30.33 +/- 5.25), (26.36 +/- 6.43) and (20.13 +/- 6.47) respectively. In 69 patients with HBeAg negative,HBV DNA loads were (5.14 +/- 1.84), (5.49 +/- 1.75 ) and (4.62 +/- 1.65) log10 copies/ml while MELD scores were 32.38 +/- 9.95, 28.17 +/- 6.82 and 26.19 +/- 5.56 in sequence. Compared with the same phase between HBeAg-positive group and HBeAg-negative group, significant differences in both HBV DNA loads and MELD scores were found only at the phase of 29-90 d (P < 0.05). In multiple comparisons among three phases, regardless of the HBeAg status,there wasn't significant difference for HBV DNA loads (P > 0.05). But increasing MELD scores are associated with the disease exacerbation and significant differences were found (P < 0.05).
To initiate acute-on-chronic hepatitis B liver failure, serum HBV DNA loads of HBeAg-positive patients are higher than that of HBeAg-negative ones. Once ACLF has been initiated,sustained high HBV DNA loads may promote the disease worsened and be fatal regardless of the HBeAg status.
