摘要: 目的 探讨血清病毒外膜大蛋白(LHBs)与乙型肝炎病毒(HBV)感染和复制的相关性。方法 检测282例乙型肝炎患者和30名健康对照者血清HBV DNA载量、LHBs和乙型肝炎e抗原(HBeAg)。以HBV DNA载量为标准,对LHBs和HBeAg进行对比分析。结果 HBV DNA载量<103拷贝/mL的107例乙型肝炎患者中LHBs阳性9例(8.41%),HBeAg阳性8例(7.48%);LHBs、HBeAg与HBV DNA载量相同等级的线性相关系数分别为0.972 1和0.837 0(P<0.01、P<0.05);LHBs与HBeAg诊断HBV感染的敏感性分别为92.57%、62.35%,特异性分别为82.52%、77.17%,阳性预测值分别为77.43%、64.08%,阴性预测值分别为59.18%、51.22%,准确率分别为97.05%、89.16%。结论 LHBs能较好地反映HBV复制情况,对乙型肝炎患者进行LHBs、HBV DNA及HBeAg联合检测将有助于疾病的诊断、疗效观察及预后判断。

Abstract: Objective To investigate the correlation of serum hepatitis B virus (HBV) large envelope protein (LHBs) with HBV infection and replication. Methods Serum HBV DNA load, LHBs and hepatitis B e antigen (HBeAg) of 282 patients with hepatitis B and 30 healthy controls were detected. LHBs was compared with HBeAg basing on HBV DNA load. Results Among 107 patients whose serum HBV DNA loads were <103 copies/mL, 9(8.41%) patients were LHBs positive, and 8(7.48%) patients were HBeAg positive. The linear correlation coefficients of LHBs and HBeAg with the scale of HBV DNA load were 0.972 1 and 0.837 0 respectively(P<0.01, P<0.05). To diagnose HBV infection, the sensitivities, specificities, positive predictive values, negative predictive values and accuracies of LHBs were 92.57%, 82.52%, 77.43%, 59.18% and 97.05%, respectively, and the values of HBeAg were 62.35%, 77.17%, 64.08%, 51.22% and 89.16%, respectively. Conclusions LHBs is a good index to reflect the situation of HBV replication. The combined determination of LHBs, HBV DNA and HBeAg of hepatitis B patients contributes to the clinical diagnosis, therapeutic effect monitoring and prognosis evaluation.
