目的探讨血清乙型肝炎病毒(hepatitis B virus,HBV)DNA检验中低于检测下限(500u/mL)实测值的临床价值。方法 180例6个月内首次血清HBV DNA>0~500u/mL慢性乙型肝炎患者,采用实时荧光定量PCR法检测其血清HBV DNA水平,3个月1次,共1a;56例监测期间血清HBV DNA最高拷贝为0u/mL为减少组,57例HBV DNA>0~103 u/mL为维持组,36例HBV DNA>103~104 u/mL为升高1组,31例HBV DNA>104 u/mL为升高2组;观察各组首次HBV DNA检测载量值,并比较随访期间血清乙型肝炎e抗原(hepatitis B virus e antigen,HBeAg)和谷丙转氨酶(glutamic-pyruvic transaminase,GPT)的变化。结果血清HBV DNA升高1组和升高2组首次血清HBV DNA载量(2.32±0.27、2.37±0.24)高于减少组(1.92±0.24)和维持组(2.12±0.29),减少组HBV DNA载量低于维持组,差异均有统计学意义(P<0.05);随访1a中,HBV DNA升高1组、升高2...

Objective To explore the clinical significance of actual numerical values below the minimum detection limit(500u/mL)in the detection of hepatitis B virus(HBV)DNA.Methods Totally 180 patients with chronic hepatitis B(CHB),initially detecting HBV DNA value >0to 500u/mL within 6months,were detected HBV DNA by real-time fluorescent quantitative-PCR once every three months for one year.The initial loading values of HBV DNA were detected in four groups:reduction group(the maximum HBV DNA value:0,n=56),maintenance...

有效抑制乙型肝炎病毒(hepatitis B virus,HBV)DNA复制是治疗慢性乙型肝炎的首要目的,血清HBV DNA水平动态变化可为临床用药提供参考[1]。目前国内使用的国产实时荧光定量PCR(fluorescentquantitative-PCR,FQ-PCR)试剂盒进行血清HBVDNA检测,其加样、核酸抽提、上样等操作尚需手
