【摘要】 目的通过HBsAg阴性献血者乙型肝炎五项标志物和HBV-DNA的相关性分析,论证HBsAg阴性血液的安全性。方法应用酶联免疫法检测乙型肝炎五项标志物;应用实时荧光定量PCR检测技术检测HBV-DNA。结果3398例HBsAg阴性献血样本,HBV-DNA检测总阳性率为2.73%,其中HBsAb(+)、HBcAb(+)模式组占6.59%,HBV-DNA阳性率为5.80%;HBsAb(+)、HBeAb(+)、HBcAb(+)模式组占4.74%,HBV-DNA阳性率为6.83%;HBcAb(+)组占6.24%,HBV-DNA阳性率为5.19%;HBeAb(+)、HBcAb(+)模式组占5.86%,HBV-DNA阳性率为4.52%;HBsAb(+)模式组占31.99%,HBV-DNA阳性率为1.56%;全阴模式组占44.59%,HBV-DNA阳性率为2.11%。结论HBsAg阴性的献血者仍然存在HBV感染的危险,特别当单独HB-cAb检测阳性或合并HBsAb、HBeAb等阳性标志物时,输血潜在感染的风险增加,应同时检测乙肝其他标志物,推行灵敏度高的核酸扩增技术筛查血液,可以进一步减少输血感染率。更多还原

【Abstract】 Objective To discuss the security of negative HBsAg blood by correlation analysis between 5 markers of hepatitis B and HBV-DNA among blood donors with HBsAg negative.Methods 5 markers of hepatitis B were detected by ELISA and HBV-DNA by real-time PCR.Results In 3 398 samples of negative HBsAg blood donors,the total positive rate of HBV-DNA was 2.73%.Among them,the type series of HBsAb(+),HBcAb(+)account 6.59%,the positive rate of HBV-DNA was 5.80%;the type series of HBsAb(+),HBeAb(+),HBcAb(+)account 4.74%,the positive rate of HBV-DNA was 6.83%;the type series of HBcAb(+)alone account 6.24%,the positive rate of HBV-DNA was 5.19%;the type series of HBeAb(+),HBcAb(+)account 5.86%,the positive rate of HBV-DNA was 4.52%;the type series of HBsAb(+)alone account 31.99%,the positive rate of HBV-DNA was 1.56%;the type series of entire negative results account 44.59%,the positive rate of HBV-DNA was 2.11%.Conclusions Blood donors with negative HBsAg still have the risk of infecting HBV,especially when HBcAb is positive alone,or combining with other positive markers such as HBsAb,HBeAb,latent transfusion’infection,the risk was remarkably increased.As a result,we should detect the other markers of hepatitis B simultaneously and carry out real-time PCR technique to screen blood in order to reduce infection rate arising from transfusion.更多还原
