| Abstract: |
| 目的探讨乙型肝炎(乙肝)病毒(HBV)表面抗原(HBsAg)阳性母亲所产婴幼儿经乙肝高效价免疫球蛋白(HBIG)和乙肝疫苗联合免疫后的免疫效果。方法对184例HBsAg阳性母亲所产婴幼儿进行随访调查, 于婴幼儿7、24、36月龄应用酶联免疫吸附试验检测血清HBv主要标志物。结果184例婴幼儿出生时HBsAg阳性者7例, HBV宫内感染率为3.80%(7/184)。分娩时HBsAg、HBeAg双阳性母亲所产婴幼儿HBV宫内感染率为11.63%(5/43);而单阳性母亲感染率约为1.42%(2/141)。7月龄随访到125例婴幼儿, 24、36月龄随访到108例婴幼儿, 仅2例出生予双阳性母亲的婴幼儿HBsAg仍持续阳性, 其余在7月龄随访时均已阴转, HBV慢性感染率为28.57%。婴幼儿出生时抗一HBs阳性率为7.02%, 经HBIG和乙肝疫苗联合免疫, 7月龄时抗一}璐s阳性率达92%, 24月龄降为72.04%。而婴幼儿抗.HBs产生与母亲双阳性无关, 与其出生时H&Ag阳性呈显著相关。双阳性39例母亲所产婴幼儿出生时25例HBeAg阳性, 随访时除2例HBsAg为阳性的婴幼儿HBeAg仍持续阳性外, 余均转阴。随访中未见婴幼儿出现HBsAg或HBeAg阳转。结论HBsAg阳性母亲所产婴幼儿经HBIG和乙肝疫苗联合免疫后免疫效果良好, 母亲双阳性可能并不影响婴幼儿联合免疫后抗一HBs的产生。 |

| Objective To study the efficacy of hepatitis B immunoglobulin(HBIG)combining hepatitis B vaccine in high risk infants born to HBsAg positive mothers through a follow-up study program.Methods 184 infants(4 twin pairs)born to HBsAg carrier mothers w}10 were consecutively recruited from December 2002 to August 2004 were followed.Major HBV ser0109ic markers in all infants were detected by enzyme-linked immunosorbent assay(ELISA)when they were at birh, at 7th, at 24thand at 36thmonths.Results 7 of the 184 infants were HBsAg positive at birth, making the transplacental intrauterine infection rate of HBV as 3.80%(7/184).125 infants were followed up at 7thmonths and 108 infants were followed up at 24thand 36thmonths.Only 2 of the 7 infants born to HBsAg-positive and HBeAg-positive mothers were persistently sera positive for HBsAg, making the chronic infection rate of HBV as 28.57%.The other 140 infants were HBsAg negative during the follow-up period.The rate of detectable anti-HBs in infants was 7.02%at birth.After infants were immunized by HBIG combining hepatitis B vaccine, the anti-HBs-positive rate reached 92%at 7∞months, and gradually descended thereafter.72.04%of the infants at 24thand 60%at 36th months showed detectable levels of anti-HBs.There was significant correlation between the produce of anti-HBs in infants and HBsAg-positive at birth while HBsAg-positive and HBeAg-positive in mothers did not relate to the produce of anti-HBs in their infants.of 39 infants born to HBsAg-positive and HBeAg-positive mothers, 25 showed detectable ievels of HBeAg.During the follow-up peirod, HBeAg was still detectable in 2 infants who were also HBsAg positive and the others all became HBeAg_negative but no infant became HBeAg-positive.Conclusion The efficacy of HBIG combining hepatitis B vaccine in highrisk infants was fine. |
