摘要: 目的 探讨PreS1抗原检测的临床价值。方法 采用酶联免疫吸附试验法检测421例慢性乙型肝炎患者血清PreS1抗原和HBV标记物;采用荧光定量PCR法检测HBV DNA。结果 在421例慢性乙型肝炎患者中,HBV DNA阳性者367例,其中PreS1Ag阳性者188例(51.2%),HBeAg阳性者119例(32.4%),后两者有显著性差异(P<0.01);在高HBV DNA载量(105~107copies/ml和>107copies/ml)组患者中,PreS1Ag阳性率(60.2%,60.0%)显著高于HBV DNA阴性组(33.3%)和低载量(103~105copies/ml)组(41.9%,P<0.01);但在421例患者中,PreS1Ag阳性率(48.9%)低于HBV DNA(87.2%,P<0.01)。结论 PreS1Ag能够较HBeAg更好地反映HBV在体内的复制状态,但尚不能代替HBV DNA的检测。

Abstract: Objective To investigate the clinical value of PreS1 antigen detection in the diagnosis of chronic hepatitis B. Methods In 421 chronic hepatitis B patients,the PreS1Ag and HBV markers in serum were detected by ELISA,and HBV DNA by fluorescence quantitative PCR. Result The positive rate of PreS1Ag(51.2%) was higher than HBeAg(32.4%)in 367 HBV DNA positive chronic hepatitis B patients(P<0.01);the positive rates of PreS1Ag in high(105~107 copies/ml and>107 copies/ml,60.2% and 60.0%) were higher than in low serum HBV DNA load(103~105 copies/ml,41.9%) and in negative group(33.3%,P<0.01);But in 421 patients,the positive rate of PreS1Ag(48.9%) was lower than HBV DNA(87.2%,P<0.01). Conclusion PreS1Ag is more sensitive than HBeAg to reflect the HBV replication in chronic hepatitis B patients,but can’t replace the detection of HBV DNA.
