چکیده
The hepatitis B core antigen (HBcAg) is an important target for antiviral response in chronic hepatitis B (CHB) patients. However, the correlation between HBcAg in the hepatocyte nucleus and nucleos(t)ide analogue (NA) therapeutic response is unclear. We sought to evaluate the role of HBcAg by analysing liver biopsies for viral response in NA-naïve hepatitis B e antigen (HBeAg) positive (+) CHB patients via immunohistochemistry (IHC). A total of 48 HBcAg-negative (-) patients and 48 HBcAg (+) patients with matching baseline characteristics were retrospectively analysed for up to 288 weeks. Virological response (VR) rates of patients in the HBcAg (-) group were significantly higher at week 48 and 96 than the HBcAg (+) group (77.1% versus 45.8% at week 48, respectively, P = 0.002 and 95.3% versus 83.3% at week 96, respectively, P = 0.045). The serological negative conversion rate of HBeAg was significantly higher in the HBcAg (-) than in the HBcAg (+) group from week 96 to 288 (35.4 % versus 14.6% at week 96, respectively, P = 0.018; 60.4% versus 14.6%, respectively, P < 0.001 at week 144; 72.9% versus 35.4%, respectively, P < 0.001 at week 288). The cumulative frequencies of VR and lack of HBeAg were higher in the HBcAg (-) group (both P < 0.05). Binary logistic regression analysis showed that HBcAg (-) was the predictor for the lack of HBeAg (OR 4.482, 95% CI: 1.58-12.68). In summary, the absence of HBcAg in the hepatocyte nucleus could be an independent predictor for HBeAg seroconversion rates during NA-naïve treatment in HBeAg (+) CHB patients.

BACKGROUND AND PURPOSE The application of nucleos(t)ide analogues in hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) has not yet been widely accepted. Therefore, we conducted a metaanalysis of prospective and retrospective studies to examine the efficacy and safety of nucleos(t)ide analogues in treating HBV-related ACLF. MATERIAL AND METHODS Two independent reviewers ide...

The emergence of new and more potent treatment options has markedly changed the treatment landscape of chronic hepatitis B. Both peginterferon and nucleos(t)ide analogues have considerable advantages and limitations, and current treatment guidelines refrain from clearly suggesting a first-line treatment option. Peginterferon offers the advantage of higher sustained response rates in both hepati...

BACKGROUND Serum levels of hepatitis B virus (HBV) DNA are an important predictor of the risk of hepatocellular carcinoma (HCC) in patients with chronic HBV infection. However, little is known about whether high levels of hepatitis B surface antigen (HBsAg) increase the risk for HCC. METHODS We investigated 167 patients who were treated with nucleos(t)ide analogues (NA) for at least 2 years (...

International guidelines recommend lifelong nucleos(t)ide analogue (NA) treatment in individuals with chronic hepatitis B (CHB) infection who are hepatitis B e antigen (HBeAg) seronegative, because hepatitis B surface antigen (HBsAg) seroconversion is rarely achieved. However, after terminating therapy, sustained responses and HBsAg loss have been observed. Clinical characteristics identifying ...
