| 目的 比较新生儿接种5 μg和10 μg重组酵母乙型肝炎(乙肝)疫苗后抗-HBs血清应答状况.方法 以山东、江苏、上海、广西、北京5省(自治区、直辖市)为研究现场,采用5 μg重组啤酒酵母乙肝疫苗(HepB-SC)和l0μg重组汉逊酵母乙肝疫苗(HepB-HP),按照“0-1-6”免疫程序完成初免的7～ 12月龄健康婴儿.调查对象采用问卷调查并采集静脉血,应用化学发光微粒子免疫分析法(CMIA)定量检测抗-HBs.抗-HBs＜ 10 mIU/ml者采用CMIA检测HBsAg,HBsAg阴性者采用巢式PCR方法检测HBV-DNA.比较不同HepB初免后的抗体应答率和抗体水平,采用多因素分析方法确定HepB种类对抗体阳转率和抗体水平的影响.结果 共观察8947名5μgHepB-SC初免(5μg组)和4576名10 μg HepB-HP初免(10μg组)婴儿.5μg组无应答、低应答、正常应答和高应答率分别为1.88％、15.18％、61.42％和21.52％,10μg组分别为0.15％、2.16％、29.42％和68.26％;5 μg组无应答、低应答和正常应答率高于10μg组,高应答率低于10 μg组,各应答率之间差异均有统计学意义(P＜0.01).5 μg组和10μg组初免后抗-HBs几何平均浓度分别为354.81mIU/ml(95％CI:338.84～363.08 mIU/ml)和1778.28mIU/ml(95％CI:1698.24～1819.70mIU/ml),差异有统计学意义(F=4517.17,P＜0.001).多因素分析显示,排除采血月龄、性别、出生体重、早产、母亲分娩前HBsAg状态等因素影响,两种HepB初免后抗体阳性率和抗体水平的差异仍有统计学意义.结论 新生儿使用10 μg HepB-HP初免抗体应答优于5μg HepB-SC. |

| Objective To compare the antibody response induced by primary immunization with 5 μ g and 10 μ g hepatitis B vaccine made by recombinant DNA techniques among the newborns.Methods Healthy infants who had completed primary immunization with 5 μg hepatitis B vaccine made by recombinant dexyribonucleic acid techniques in Saccharomyces (Hep-SC) or 10 μg hepatitis B vaccine made by recombinant dexyribonucleic acid techniques in Hansenula polymorpha (HepB-HP) were included in the study.Kids under study were 7-12 months of age and had been on 0-1-6 schedule.Standardized questionnaire was used and blood samples were collected.The titer of antibody to hepatitis B surface antigen (anti-HBs) was detected by Chemiluminescence Microparticle Imunoassay (CMIA).If anti-HBs happened to be under 10 mIU/ml,HBV DNA was further detected by nested-PCR to distinguish occult hepatitis B virus infection.Sero-conversion rate and titer of anti-HBs were compared between the two kinds of hepatitis B vaccines.Multivariate analysis was used to find the relationship between the kind of hepatitis B vaccine as well as the antibody response after debugging the other influencing factors including month-age,gender,birth-weight,premature birth and mother' s HBsAg status.Results 8947 infants vaccinated with 5 μg HepB-SC and 4576 infants vaccinated with 10 μg HepB-HP were investigated.In the 5 μg group,the rates of non-,low-,normal- and high-response were 1.88％,15.18％,61.42％ and 21.52％ respectively.In the 10 μg group,the corresponding rates were 0.15％,2.16％,29.42％ and 68.26％ respectively.The non-,low-,normal-response rates were all higher in 5 μg group than in 10 μg group (P＜0.01),while the high-response rate was much higher in 10 μg group than in 5 μ g group (P＜0.01).The geometric mean concentration (GMC) of anti-HBs were 354.81 mIU/ml (95％ CI:338.84-363.08 mIU/ml) and 1778.28 mIU/ml (95％CI:1698.24-1819.70 mIU/ml) in the 5 μg group and 10 μg group respectively.The GMC was statistically higher in the 10 μg group than in the 5 μg group (P＜0.001).The seroconversion rate and GMC were significantly different between the two groups even after debugging the other influencing factors.Conclusion Better anti-HBs response could be achieved by primary immunization with 10 μg HepB-HP than with 5 μg HepB-SC among newborns.? |
