孕妇乙型肝炎标志物调查和宫内感染分析

目的 了解浙江省湖州地区孕妇乙型肝炎病毒(HBV)感染程度和官内感染的关系.方法 采用时间分辨免疫荧光分析法测定乙型肝炎标志物(HBVM),荧光定量PCR技术测定HBV-DNA.结果 1262例孕妇HBVM感染阳性率:HBsAg、HBsAb、HBeAg、HBeAb、HBcAb总体阳性率分别为2.6%(33/1262),38.2%(482/1262),0.9%(11/1262),22.6%(285/1262)和23.1%(291/1262).33例血清HBsAg阳性孕妇中,11例HBeAg阳性者HBV-DNA多为高载量,宫内感染率是6/11;22例HBeAg阴性者HBV-DNA多为低载量,宫内感染率是2/22;两者比较差异有统计学意义(P<0.01).总计HBsAg阳性孕妇宫内感染率是24.2%(8/33).结论 浙江省湖州地区孕妇乙型肝炎病毒感染率较低.孕妇血清HBeAg阳性和HBV-DNA含量高,易发生宫内感染.

Pregnant women hepatitis B markers investigation and analysis of intrauterine infection

Objective To investigate the relationship between the hepatitis B virus (HBV) infection in pregnant women and intrauterine infection in local region. Methods The markers of hepatitis B (HBVM) were determined by time-resolved fluoroimmunoassay and HBV-DNA were determined by FQ-PCR. Results A 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, HBeAb positive respectively. In 33 eases 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).Conclusion HBV 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.
