摘要: 目的 通过分析HBV Pre-S1抗原与HBeAg和HBV DNA的相关性,以探讨其在诊断HBV复制的临床价值。方法 采用ELISA法、荧光定量PCR法检测450例HBsAg阳性及50例健康对照血清标本的HBV Pre-S1抗原、血清HBV标志物、HBV DNA及肝功能。结果 在450例HBsAg阳性血清中,HBeAg、Pre-S1抗原和HBV DNA阳性率分别为40.0%、57.3%和61.6%;Pre-S1抗原、HBV DNA阳性率在HBeAg阴性与阳性组间差异有统计学意义(x2=84.2,x2=110.7,P<0.01);PreS1抗原与HBeAg和HBV DNA均存在相关性(x2=86.5,x2=272.1,P<0.01);Pre-S1抗原阳性组AST、ALT、TBl、γ-GT均高于阴性组(P<0.01);当HBV DNA拷贝数的对数值>2.7lg copies/ml时,Pre-S1抗原诊断HBV复制的敏感度为87.7%,特异度为91.3%,准确性为89.1%,阳性预测值为94.2%,阳性似然比为10.1,优势比为75.3,而HbeAg则分别为59.2%、90.8%、71.3%、91.1%、6.43和14.2。结论 HBV Pre-S1抗原与HBeAg和HBV DNA均有较好的相关性,可作为一项新的病毒复制的指标。

Abstract: Objective To explore the clinical value of hepatitis B virus Pre-S1 antigen in the diagnosis of viral replication. Methods 450 HBsAg positive and 50 healthy control serum specimens were collected,and the Pre-S1 antigen and HBVM were detected by ELISA,HBV DNA levels by fluorescence quantitative polymerase chain reaction(FQ-PCR),and liver fuction by automatic biochemical analyzer respectively. Results The positive rates of HBeAg,Pre-S1 antigen and HBV DNA in all patients were 40.0%,57.3% and 61.6%,respectively;there were significant differences in the positive rates of Pre-S1 antigen and HBV DNA in HBeAg negative and positive group(x2=84.2,x2=110.7,P<0.01);Pre-S1 antigen were correlated with HBeAg and HBV DNA(x2=86.5,x2=272.1,P<0.01);AST,ALT,TBil and γ-GT in Pre-S1 antigen positive group were higher than those in negative group(P<0.01);When serum HBV DNA was more than 2.7lg copies/ml as the cut-off value for the HBV replication,the sensitivity,specificity,accuracy,positive predictive value,positive likelihood ratio and odds ratio of Pre-S1 were 87.7%,91.3%,89.1%,94.2%,10.1 and 75.3 respectively,while those of HBeAg were 59.2%,90.8%,71.3%,91.1%,6.43 and 14.2 respectively. Conclusions Pre-S1 antigen is correlated with HBeAg and HBV DNA for HBV replication.
