Impact of HBV replication in peripheral blood mononuclear cell on HBV intrauterine transmission
This study determined the effect of hepatitis B virus (HBV) replication in peripheral blood mononuclear cell (PBMC) from HBsAg-positive mothers on HBV intrauterine transmission. A total of 150 HBsAg-positive mothers and their neonates were recruited in this study. Within 24 h after birth, HBV serological markers, serum HBV DNA, PBMC HBV relaxed circular DNA (rcDNA), and covalently closed circular DNA (cccDNA) were measured in the HBsAg-positive mothers and their neonates before passive-active immune prophylaxis. The relationship between HBV replication in PBMC and HBV intrauterine transmission was examined through Chi-square test and logistic regression. The rate of HBV intrauterine transmission was 8.00% (12/150) in the 150 neonates born to HBsAg-positive mothers. The positivities of PBMC HBV rcDNA and cccDNA in the HBsAg-positive mothers were 36.67% (55/150) and 10% (15/150), respectively. Maternal PBMC HBV cccDNA was a risk factor of HBV intrauterine transmission (OR= 6.003, 95% CI: 1.249–28.855). Maternal serum HBeAg was a risk factor of PBMC HBV rcDNA (OR= 3.896, 95% CI: 1.929–7.876) and PBMC HBV cccDNA (OR= 3.74, 95% CI: 1.186–11.793) in the HBsAg-positive mothers. Administration of hepatitis B immune globulin was a protective factor of PBMC HBV cccDNA (OR= 0.312, 95% CI: 0.102–0.954) during pregnancy. The positivity of PBMC HBV rcDNA was related to that of cccDNA in the HBsAg-positive mothers (c2=5.087, P= 0.024). This study suggests that PBMC is a reservoir of HBV and an extrahepatic site for virus replication and plays a critical role in HBV intrauterine transmission.
