Objective: To compare the difference of HBV DNA levels and HBV genotypes between the patients with primary hepatocellular carcinoma (HCC) and liver cirrhosis who infected with hepatitis B virus.
Methods: Total 430 patients with hepatitis B were enrolled and further divided into the HCC group (210 cases) and liver cirrhosis group (HBV LC, 220 cases). The levels of HBV DNA and HBV genotypes were detected in all of the serum samples from the two groups, and the differences in the genotypes and virological markers between HCC patients and HBV LC patients were further analyzed.
Results: The positive rates of HBV DNA of HCC patients and HBV LC patients were 84.3% (177/210) and 94. 5% (208/220), respectively. The mean values of serum HBV DNA in HCC patients and HBV-LC patients were (5.06 +/- 1.01) log10 cps/ml and (5.36 +/- 1.13) log10 cps/ml, respectively. The positive rates of HBV DNA and the mean values of serum HBV DNA were higher in HBV-LC patients than those in HCC patients (P < 0.01). Furthermore, the main genotype was C in both groups and the distribution of genotype C and genotype B had no statistical difference.
Conclusions: Mainly presented as a C genotype in both groups, the total levels of serum HBV DNA in HCC patients were lower than those in HBV-LC patients.

Background: Hepatitis B virus (HBV) infection remains a major health challenge in Nigeria, with high prevalence rates among pregnant women. The prevalence of overt and occult hepatitis B infection (HBI and HBI) among pregnant women was investigated to understand the burden and associated risk factors in this population.
Methods: A cross-sectional study was conducted among 200 pregnant women.

Background: Hepatitis B virus (HBV) is categorized as one of the smallest enveloped DNA viruses and is the prototypical virus of the Hepatoviridae family. It is usually transmitted through body fluids such as blood, semen, and vaginal secretions. The majority (more than 95%) of immunocompetent adults infected with HBV spontaneously clear the infection.

The persistent global burden of hepatitis B virus (HBV) infection has prompted ongoing investigations into host determinants of viral control. In this study, we investigate the regulatory influence of the host gene cleavage stimulation factor subunit 2 (CSTF2) on HBV replication dynamics. We demonstrate differential CSTF2 expression across the spectrum of HBV infection phases, with upregulated expression noted during the immune-reactive and inactive carrier states compared with the immune-tolerant phase.

Background: Chronic hepatitis B virus (HBV) infection is a common but underdiagnosed and undertreated health condition and is the leading cause of hepatocellular carcinoma (HCC) worldwide. HBV (rated a Grade 1 carcinogen by the International Agency for Research on Cancer) drives the transformation of hepatocytes in multiple ways by inducing viral DNA integrations, genetic dysregulation, chromosomal translocations, chronic inflammation, and oncogenic pathways facilitated by some HBV proteins. Importantly, these mechanisms are active throughout all phases of HBV infection.

Background: Previous studies primarily focused on the effects of ALT and virology, but there is a lack of research on the correlations of HBcrAg and pgRNA, two novel virologic markers, with immunological parameters in pregnant women with CHB undergoing prophylactic antiviral intervention.
Methods: We conducted a retrospective cohort study involving 28 HBeAg-positive pregnant women with CHB undergoing prophylactic antiviral intervention. Clinical data, virological markers (HBV DNA, HBsAg, HBeAg, HBcrAg and pgRNA) and 28 cytokines were detected at three time points: 24-28 weeks gestation (before prophylactic antiviral intervention), near birth and within 3 months postpartum.
