AbstractBACKGROUND: Both serum hepatitis B virus (HBV) DNA and RNA can reflect intrahepatic covalently closed circular DNA (cccDNA) activity. However, correlations among viral markers haven't been fully explored.
OBJECTIVES: Here we investigated the correlations between serum HBV RNA and other viral markers in acute hepatitis B patients and treatment-naïve chronic HBV-infected individuals.
STUDY DESIGN: The serum viral markers of 19 acute hepatitis B patients and 84 treatment-naïve chronic HBV-infected individuals at different infection stages were quantified. Correlations among viral markers were analyzed by Pearson's or Spearman's correlation analysis.
RESULTS: Serum viral markers and intrahepatic cccDNA levels were lower in acute hepatitis B patients than in treatment-naïve chronic HBV-infected individuals. Serum HBV RNA levels were positively correlated with serum HBV DNA, HBsAg and intrahepatic cccDNA levels in HBeAg-positive chronic HBV-infected individuals. Total serum HBV nucleic acids (HBV DNA plus RNA) showed superiority in reflecting intrahepatic cccDNA activity. Stratified analysis revealed that such correlations were only found in HBeAg-positive chronic hepatitis B phase. Moreover, high-frequency R193M and P196A mutations were found in the RT region of HBV polymerase leading to lower serum HBV DNA and higher serum HBV RNA levels in HBeAg-negative chronic HBV infection phase.
CONCLUSIONS: HBV replication capability was lower in acute hepatitis B patients than in chronic HBV-infected individuals. In treatment-naïve HBeAg-positive chronic HBV-infected individuals, serum HBV DNA plus RNA showed superiority in reflecting intrahepatic cccDNA activity than each alone. Moreover, mutated RT region of HBV polymerase might lead to the attenuated reverse transcriptional activity of HBV polymerase in HBeAg-negative chronic HBV infection phase.

抽象
背景:

血清乙型肝炎病毒(HBV)DNA和RNA均能反映肝内共价闭合环状DNA(cccDNA)的活性。然而,病毒标记之间的相关性还没有被充分探索。
目的:

在这里,我们调查了血清HBV RNA和其他病毒标志物在急性乙型肝炎患者和初治慢性HBV感染者之间的相关性。
学习规划:

对19例急性乙型肝炎患者和84例初治慢性HBV感染者在不同感染阶段的血清病毒标志物进行定量。通过皮尔逊(Pearson)或斯皮尔曼(Spearman)相关分析来分析病毒标记之间的相关性。
结果:

急性乙型肝炎患者的血清病毒标志物和肝内cccDNA水平低于未治疗的慢性HBV感染者。血清HBV RNA水平与HBeAg阳性慢性HBV感染者血清HBV DNA,HBsAg和肝内cccDNA水平呈正相关。总血清HBV核酸(HBV DNA加RNA)显示反映肝内cccDNA活性的优越性。分层分析显示,这种相关性仅在HBeAg阳性的慢性乙型肝炎期发现。此外,在HBV聚合酶的RT区发现高频R193M和P196A突变,导致HBeAg阴性慢性HBV感染期中血清HBV DNA降低和血清HBV RNA水平升高。
结论:

急性乙型肝炎患者HBV复制能力低于慢性HBV感染者。在未经治疗的HBeAg阳性的慢性HBV感染者中,血清HBV DNA加RNA显示出反映肝内cccDNA活性的优势。此外,HBV聚合酶的突变RT区可能导致HBV聚合酶在HBeAg阴性慢性HBV感染阶段的逆转录活性减弱。
