[Correlation of hepatitis B e antigen with hepatitis B virus DNA in the serum of chronic hepatitis B patients after treatment].

Objective: To analyze the correlation of hepatitis B virus (HBV) DNA with the serological markers of HB in the serum of chronic HB patients after treatment PCR method and to analyze the status of these markers and the multiplication of virus.

Methods: Peripheral blood samples were collected from 480 chronic HB patients, aged 15 - 50, who had been treated by anti-nucleotide drugs or traditional Chinese herbs and showed normal ALT/AST. Both COBAS AMPLICOR HBV MONIORTM kit (internal-standard PCR method) and Light Cycler real time fluorescent quantitative PCR instrument (external-quantitative standard PCR method) were used to measure the HBV DNAS level.
