慢性乙型肝炎外周血单个核细胞内HBV-DNA与血清HBV-DNA及HBeAg表达关系的研究

目的研究慢性乙型肝炎患者外周血单个核细胞(PBMC)内HBV-DNA和血清中HBV-DNA表达量、e抗原表达的关系。方法采用聚合酶链反应(PCR)检测208例慢性乙型肝炎患者PBMC内HBV-DNA,应用荧光定量聚合酶链反应(FQ-PCR)检测血清中HBV DNA含量,应用酶联免疫吸附(ELISA)法检测乙肝血清标志物。结果208例慢性乙型肝炎患者PBMC内HBV-DNA阳性106例、阴性102例。HBV-DNA(PBMC)阳性组、阴性组血清HBV-DNA定量≥1.0E5患者比例分别为91.5%(97例)、45.1%(46例)(χ2=52.12,P<0.01);HBeAg阳性率分别为76.4%(81例)、50.9%(52例)(χ2=21.55,P<0.01)。结论PBMC内HBV-DNA的检测与血清中HBV-DNA定量检测及HBeAg阳性率存在明显的正相关。提示血清HBV-DNA高载量的HBeAg阳性患者外周血单个核细胞感染HBV-DNA明显增加。

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

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.
