乙型肝炎病毒前S1抗原与相关血清标志物联合检测的临床价值探讨

目的探讨乙型肝炎病毒(HBV)前S1抗原在感染者不同模式血清标志物(HBV-M)中的阳性表达情况,评价其临床应用价值。方法采用酶联免疫吸附试验(ELISA)法检测386例乙型肝炎(下称乙肝)病毒表面抗原(HBsAg)阳性血清标本的乙肝病毒前S1抗原和HBsAg、抗-HBs、乙肝病毒e抗原(HBeAg)、抗-HBe、抗-HBc,并对检测结果进行比较分析。结果前S1抗原在HBsAg阳性、HBeAg阳性、抗-HBc阳性和HBsAg阳性、HBeAg阳性组的阳性率显著增高,分别为87.1%和84.6%;在HBsAg阳性、抗-HBc阳性、和HBsAg阳性、抗-HBe阳性、抗-HBc阳性以及HBsAg阳性组前S1抗原的阳性率依次为60.0%、49.8%和33.3%;HBeAg阳性组的前S1抗原阳性率86.7%,明显高于HBeAg阴性组51.0%(P0.01);386例乙型肝炎病毒感染者中,前S1抗原阳性率为60.1%,HBeAg阳性率为25.4%,两者差异有统计学意义(P0.01)。结论前S1抗原作为HBV感染、复制的指标较HBeAg更敏感,可补充和完善乙肝五项检测的不足,尤其对HBeAg阴性的血清,检测前S1抗原,能更好地反映病毒的复制状态和传染性,同时对病情的预后和疗效的判断也有一定的指导意义。

Investigation of the clinical significance by detecting both the hepatitis B virus Pre-S1 antigen and the related serum markers

Objective To investigate the positive rate of pre-S1 antigen in different models of serum HBV markers(HBV-M) in the serums of patients with hepatitis B virus and appraise its clinical significance.Methods ELISA method was used to detect the hepatitis B virus pre-S1 antigen,HBsAg,HBsAb,HBeAg,HBeAb and HBcAb in the serums from 386 samples of patients with hepatitis.The detected results were analyzed comparatively.Results Pre-S1 positive rate was 87.1% in the group with HBsAg positive,HBeAg positive and anti-H...
