Objective: To observe the HBV serum markers and HBV DNA expressions of the neonates born to the HBsAg-positive mothers.
Methods: By detecting serum immunity markers of hepatitis B virus (5 items) and serum HBV DNA of 283 neonates (a pair of twins) born to 282 HBsAg-positive mothers.
Results: 12 patterns emerge from the study of the hepatitis B serum markers of 283 neonates. Topping the list is the combination of HBeAg and anti-HBc positive accounting for 48.41% (137/283), followed by the combination of anti-HBe and anti-HBc positive accounting for 22.26% (62/283). The third highest combination is that of HBsAg, HBeAg and anti-HBc positive accounting for 12.37% (35/283). There are five combinations accounting for 16.61% (47/283), each with HBsAg-positive. No case is found of the five items all negative or only HBsAb positive. Five cases are detected of serum HBV DNA > or = 1 x 103 IU/ml accounting for 1.77%.
Conclusions: Neonates born to HBsAg-positive mothers display complex patterns of serum hepatitis B markers, the dominant pattern being the combination of HBeAg and anti-HBc positive. Cases of serum HBV DNA > or = 1 x 10(3) IU/ml are rare.

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.
