摘要
目的探讨HBV—DNA的检出情况与乙肝两对半结果之间的关系。方法运用荧光定量PCR(FQ—PCR)检测623例疑似乙肝患者血清中的HBV—DNA,同时运用ELISA方法进行两对半指标的检测,并对结果进行相关性探讨。结果HBsAg(+)HBeAg(+)HBcAb(+)组(大三阳组)患者血清HBV—DNA检出率为97.0%(255/263),平均拷贝数为7.16E+06IU/ml;HBsAg(+)HBeAb(+)HBcAb(+)组(小三阳组)患者血清HBV—DNA检出率为83.3%(200/240),平均拷贝数为5.23E+05IU/ml;HBsAg(+)HBcAb(+)组血清HBV—DNA检出率为53.8%(43/80),平均拷贝数为2.87E+05IU/ml;HBsAb(+)组血清HBV—DNA检出率为50%(1/2),平均拷贝数为1.83E+03IU/ml;HBcAb(+)组血清HBV—DNA检出率为20%(1/5),平均拷贝数为3.00E+04IU/ml;HBsAb(+)HBeAb(+)HBcAb(+)组血清HBV—DNA捡出率为40%(2/5),平均拷贝数为9.23E+03IU/mI;HBsAg(+)组血清HBV—DNA检出率为13.3%(2/15),平均拷贝数为1.18E+07IU/ml;HBV—M全阴性组HBV—DNA检出率为12.5%(1/8),平均拷贝数为1.23E+04IU/ml。结论HBV—M阴性患者仍有HBV—DNA阳性者,因此在检测中应联合应用两种方法进行检测,提高检出率,避免漏诊,为临床HBV感染、复制及传染性的判断以及指导治疗提供更为可靠的判定依据。
Objective To explore the relationship between detection of HBV - DNA and routine detection of HBV. Methods HBV - DNA was detected with fluorescent quantitative PCR (FQ - PCR ) and HBV was routinely determined with ELISA in serum samples from 623suspected eases of hepatitis B. Meanwhile,the correlation of results between the two methods was analyzed. Results The detecting rate of HBV -DNA was 97.0% (255/263) and the mean copy number was 7. 16E + 06 IU/ml in patients of HBsAg( + ), HBeAg( + ) and HBcAb ( + ) (group A), 83.3% (200/240)and 5.23E +05 IU/ml in patients of HBsAg( + ) ,HBeAb( + ) and HBcAb( + ) (group B), 53.8% (43/80) and 2. 87E + 05 IU/ml in patients of HBsAg( + ) and HBcAb( + ) (group C) ;Furthermore, they were respectively ;50% (1/2) and 1.83E +03 IU/ml in patients of HBsAb( + ), 20% (1/5) and 3.00E +04 IU/ml in patients of HBcAb( + ) ,40% (2/5) and 9. 23E +03 IU/ ml in patients of HBsAb( + ), HBeAb( + ) and HBeAb( + ) ,13.3% (2/15) and 1.18E +07 IU/ml in patients of HBsAg( + ) ;12. 5% ( 1/ 8) and 1.23E + 04 IU/ml in HBV - M - negative patients. Conclusion HBV - DNA positivity may appear in HBV - M - negative patients. Therefore, the 2 methods should be simultaneously used in the detection of HBV infection to promote the detecting rate to provide more reliable evidence for judgment of HBV infection, duplication and infectivity and its treatment in clinical practice.
