摘要
目的了解乙型肝炎病毒(HBV)感染不同血清学标本酶联免疫吸附反应(ELISA)阳性与HBV-DNA阳性结果的比较情况。方法对200例血清同时进行荧光定量聚合酶链反应(FQ-PCR)检测HBV-DNA及ELISA方法测定HBVM。结果乙型肝炎病毒表面抗原(HBsAg)阳性组HBV-DNA阳性率为80.7%(146/181),HB-sAg(-)组HBV-DNA阳性率为5.6%(1/18),二者差异有统计学意义(P<0.001)。其中75例HBsAg、乙型肝炎病毒e抗原(HBeAg)、乙型肝炎病毒核心抗原(HBcAg)均为阳性的血清HBV-DNA阳性率为100.0%(75/75),HBsAg、乙型肝炎病毒抗体(抗-HBe)、乙型肝炎病毒核心抗体(抗-HBc)均为阳性组血清HBV-DNA阳性率为77.9%(46/59),HBsAg(+)、抗-HBc(+)组血清HBV-DNA阳性率为53.2%(25/47),乙型肝炎病毒表面抗体(抗-HBs)阳性、抗-HBe(+)、HBcAg(+)组血清HBV-DNA阳性率为12.5%(1/8)。结论ELISA检测结果相同的患者,其体内HBV-DNA的复制情况存在很大的差别。判断肝脏中HBV复制及有无传染性依据HBsAg阳性或HBeAg阳性是不够的,易造成部分乙型肝炎的漏诊。对于HBsAg阴性只要有HBV感染后的任何血清学依据,都应检测血清HBV-DNA作为诊断乙型病毒性肝炎的进一步筛选,必要时应同时行肝活检加以证实。
Objective To investigate different combination of ELISA positive HBV markers and to compare them with HBV-DNA results. Methods FQ-PCR and ELISA assay were applied simultaneously to measuring 200 cases of serum samples for HBVM. Results The HBV-DNA positive rate of HBsAg(+) and HBsAg(-) group was 80.7% (146/181) and 5.6% (1/18),respectively. The difference of HBV-DNA positive rate between the two groups was significant (P〈0. 001). The HBV-DNA positive rate of HBsAg ( + ) /HBeAg( + ) /HBcAg( + ) group, HBsAg( + )/anti-HBe ( + )/anti-HBc ( + ) group, HBsAg ( + )/anti-HBc ( + ) group, and anti-HBs ( + )/anti-HBe (+)/HBcAg(+) group was 100.0%(75/75) ,77.9%(46/59), 53.2%(25/47) and 12.5%(1/8) ,respectively. Conclusion There may be significant difference of HBV-DNA replication when ELISA results were the same. Simple HBsAg(+) or HBeAg(+) is insufficient to dignose HBV replication and HBV infection. Even to patients with HBsAg(-), if there is any serological evidence for HBV infection, serum HBV-DNA ought to be detected for further diagnosis of viral hepatitis B, and liver biopsy may be performed to confirm the diagnosis if necessary.
