HBsAg阳性产妇所生新生儿的HBV血清标志物及HBVDNA的检测结果分析

Analysis of the test results of HBV serum markers and HBV DNA of the neonates born to HBsAg-positive mothers

目的 观察HBsAg阳性产妇所生新生儿血清乙型肝炎标志物及HBV DNA的表达.方法 对282例HBsAg阳性产妇所生283例（一例双胞胎）新生儿进行乙型肝炎病毒血清免疫标志物（五项）和血清HBV DNA检测.结果 283例新生儿乙型肝炎血清标志物表现为12种模式,以HBeAg、抗HBc阳性组合最多占48.41％（137/283）,其次为抗HBe、抗HBc阳性组合占22.26％（62/283）,HBsAg、HBeAg、抗HBc阳性组合占12.37％（35/283）,含HBsAg阳性的有5种组合占16.61％（47/283）,未见五项全阴和单抗- HBs阳性者.血清HBV DNA≥1×103IU/mL者5例占1.77％.结论 HBsAg阳性产妇所生新生儿血清乙型肝炎标志物表现复杂,以HBeAg、抗HBc阳性组合为主.血清HBV DNA≥1×103IU/mL不多见.

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 ≥ 1 ×103IU/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 ≥ 1 × 103IU/ml are rare.
