乙肝病毒标志物阳性产妇母乳喂养的研究
A Study on Breast Feeding to Infants of Hepatitis B Virus Markers Positive Mothers
【摘要】 目的:探讨乙型肝炎( 乙肝) 病毒携带孕妇胎儿宫内感染率和乳汁中乙肝病毒( H B V) 阳性率的相关性,分析研究乙肝血清学指标阳性产妇是否适于哺乳。方法:对52 例乙肝血清学指标阳性的产妇,应用酶联免疫吸附法和斑点杂交法分别检测脐血和初乳中的 H B V 标志物( H B V M) 以及 H B V 脱氧核糖核酸( H B V D N A) ,并对比分析。结果:孕妇 H B V 阳性与相应的脐血和初乳中的 H B V M 阳性率以及 H B V D N A 的检出率呈高度的一致性( P > 005) 。52 例 H B V M 阳性的孕妇中,脐血和初乳中 H B V D N A 的检出率均以乙肝表面抗原( H Bs Ag) 、乙肝e 抗原( H Be Ag) 及乙肝核心抗体( Anti H Bc)3 项阳性者最高(8571 % 和9286 % ) , H Bs Ag 、 H Be Ag 双项阳性者次之(80 % ) , H Bs Ag 单项阳性者最低(20 % ) 。结论: H B V 宫内传播以及初乳排毒率与母亲的 H Bs Ag 和 H Be Ag 状态密切相关。直接检测初乳中 H B V D N A 为指导哺乳的最可靠方法。血中 H Bs Ag 、 H Be Ag 和 Anti H Bc3 项阳性以及 H Bs
【Abstract】 Objective : To study theintrauterine fetalinfection rate and breast milk infection rate in hepatitis Bvirus( H B V) carrier mothers and to analyze their probability of breast feeding . Methods : To detect hepatitis Bvirus markers( H B V M) and H B V D N Ain the umbilical blood and colostrum of52 H B Vcarrier mothers by E L I S Aand the dot blot hy bridization and to analyze the results comparatively . Results : The H B V M or H B V D N A positive rate in the umbilicalblood and the colostrum was found to be highly consistent with the H B V M positive rate in the maternal blood ( P >0 05) . Mothers with allthethree markers of H Bs Ag , H Be Ag and Anti H Bc positive were detected with the highest H B V D N A positive ratein their umbilical blood and breast milk (85 71 % and 92 86 % ) . Those with both H Bs Ag and H Be Agpositive listed the second (80 % ) . Thelowest was ofthose with H Bs Ag positive (20 % ) . Conclusion : Intrauterinetrans mission rate of H B Vand the virus secreting rate in colostrum are highly related to the status of H Bs Ag , H Be Ag in themother. Direct detection of H B V D N Ais the most reliable method for conducting breast feeding . It would be better forthe mother with H Bs Ag , H Be Ag , Anti H Bc positive or H Bs Ag , H Be Ag positive to chose manualfeeding .
