OBJECTIVETo investigate the relationship between the hepatitis B virus (HBV) infection in pregnant women and intrauterine infection in local region.

METHODSThe markers of hepatitis B (HBVM) were determined by time-resolved fluoroimmunoassay and HBV-DNA were determined by FQ-PCR.

RESULTSA total of 1262 pregnant women were examined the HBVM, 2.6%, 38.2%, 0.9%, 22.6%, 23.1% subjects were identified HBsAg, HBsAb, HBeAg, HBeAb, HBcAb positive respectively. In 33 cases of serum HBsAg-positive pregnant women, HBV-DNA were observed in most of 11 cases of pregnant women with HBeAg-positive and intrauterine infection rates were 6/11. In contrast, 22 cases of pregnant women with HBeAg negative, HBV-DNA were detected lowly-loaded and intrauterine infection rates were 2/22 (P < 0.01). Intrauterine infection rates of HBV in pregnant women with HBsAg-positive were 24.2% (8/33).

CONCLUSIONHBV infective rates in pregnant women in the local region were low. Pregnant women with serum HBeAg positive and HBV-DNA high-loaded were prone to intrauterine infection.
