[The correlation of HBeAg expression and HBV-DNA in serum or peripheral blood mononuclear cells in patients with chronic hepatitis B].

ABSTRACT

OBJECTIVE: To study the relationship between HBeAg expression and HBV-DNA in serum and peripheral blood mononuclear cells (PBMCs). METHODS: 208 patients with chronic hepatitis B were included in this present study. HBV-DNA in the PBMCs were performed by polymerase chain reaction (PCR), with the serum HBV-DNA level being determined by the way of fluoresces quantities PCR (FQ-PCR). Meanwhile, HBV-GM was also detected via enzyme-linked immunosorbent assay (ELISA). RESULTS: There were 106 patients for positivity in the HBV-DNA level of PBMCs with 102 for negativity, in which the HBV-DNA high levels (HBV DNA load > or = 1.0E5) in serum were 91.5%, 45.1% (chi2=52.12, P>0.01) respectively, with 76.4% and 50.9% (chi2=21.55, P>0.01) for the positive percentage of HBeAg expression. CONCLUSION: A significantly positive correlation was found between HBV-DNA in PBMCs and serum HBV-DNA along with the positive percentage of HBeAg, indicating that obvious PBMCs' increase infected by HBV in patients with positivity of HBeAg and high level of serum HBV-DNA.
