HBV携带者血清病毒标志物和HBV DNA与肝组织中HBVcccDNA相关性的研究

Objective To investigate the correlation of sera HBV DNA and serological makers with hepatic tissue HBVcccDNA in chronic HBV carriers. Methods Real time fluorescence quantitative polymerase chain reaction (RT-PCR) were used to detect HBV covalently closed circular DNA (cccDNA) and total intrahepatic HBV DNA from 30 needle-biopsy specimens as well as HBV DNA in sera in chronic HBV carriers. Quantification of the HBsAg, HBeAg in sera were quantified using Chemiluminescence immunoassay. Results HBVcccDNA can be detected in chronic HBV carriers, which rang from 3.15 × 103 copies/mg to 1.06 × 107 copies/mg. There was a positive correlation between the cccDNA and HBVtDNA (r =0. 375, P < 0. 05 ), but there was no correlation between the cccDNA and sera HBV DNA (P =0. 174). There was a positive correlation between cccDNA and sera HBsAg quantification (r =0. 562, P <0. 001 ) but no correlation with sera HBeAg qantification ( r = 0. 152, P > 0. 05 ). Conclusion HBV cccDNA can be replicated stably in hepatic tissue in all chronic HBV carriers. HBV DNA in sera can not be indicated hepatic tissue cccDNA level. While HBsAg quantification in sera can be used as a marker of cccDNA quantification in hepatic tissue to some extent.
