摘要: 背景 导致乙型肝炎病毒(HBV)持续性感染的根本原因是共价闭合环状DNA(cccDNA)的持续性存在,现有的血清学指标难以准确反应肝细胞内cccDNA的存在状态,血清HBV RNA为cccDNA的直接转录体,能精确地反映肝细胞中cccDNA的存在状态。目的 观察低水平HBV DNA慢性乙型肝炎(CHB)患者血清HBV RNA水平,并分析其影响因素。方法 回顾性选取2018年5—7月于湖南师范大学附属第一医院确诊且符合研究标准的CHB患者,患者均处于HBV DNA低水平状态。依据患者乙肝e抗原(HBeAg)情况将患者分为HBeAg阳性患者和HBeAg阴性患者,比较其年龄、性别、血清丙氨酸氨基转移酶(ALT)水平、血清天冬氨酸氨基转移酶(AST)水平、血清乙肝表面抗原定量(qHBsAg)水平、血清HBV DNA水平、血清HBV RNA水平、血清HBV RNA水平低于检测下限发生率,分析CHB患者血清HBV RNA水平及其低于检测下限的影响因素,以及血清HBV RNA水平与ALT、AST、qHBsAg、HBeAg、HBV DNA的相关性。结果 72例患者中HBeAg阳性12例,HBeAg阴性60例。HBeAg阳性患者年龄小于HBeAg阴性患者,血清AST、qHBsAg、HBV RNA水平高于HBeAg阴性患者,血清HBV DNA水平、血清HBV RNA水平低于检测下限发生率低于HBeAg阴性患者(P<0.05)。多因素线性回归分析结果显示,HBeAg(B=0.837,t=2.634,P=0.010)是CHB患者血清HBV RNA水平的影响因素(P<0.05)。多因素Logistic回归分析结果显示,qHBsAg〔OR=1.682,95%CI(1.055,2.681),P=0.029〕、HBeAg〔OR=3.85,95%CI(1.068,13.880),P=0.039〕是CHB患者血清HBV RNA水平低于检测下限的影响因素。CHB患者血清HBV RNA水平与qHBsAg(rs=0.322,P=0.006)、HBeAg(rs=0.235,P=0.047)相关。在HBeAg阳性患者中,血清HBV RNA水平与qHBsAg(rs=0.848,P<0.001)、HBeAg(rs=0.725,P=0.008)相关。结论 不同HBeAg情况的低水平HBV DNA CHB患者血清HBV RNA水平存在较大差异,HBeAg是CHB患者血清HBV RNA水平的影响因素,qHBsAg、HBeAg是CHB患者血清HBV RNA水平低于检测下限的影响因素。

Abstract: Background The main reason that leads to persistent Hepatitis B virus (HBV) infection is covalent closed circular DNA (cccDNA).Current laboratory tests can hardy reveal the status of cccDNA in hepatocytes accurately.While HBV RNA,the transcriptome of cccDNA,can indicate the existence of cccDNA.Objective To investigate the level of serum HBV RNA in chronic hepatitis B (CHB) with low level of HBV DNA replication and analyze its influential factors.Methods CHB patients with low HBV DNA replication level from the First Affiliated Hospital of Hunan Normal University from May to July 2018 were retrospectively enrolled and divided into two groups according to their HBeAg status.Age,sex,the serum level of alanine aminotransferase(ALT),aspartate aminotransferase (AST),quantitative hepatitis B surface antigen (qHBsAg),HBV DNA,HBV RNA,and incidence of HBV RNA below the lowest limit of detection were compared between the two groups.Influential factors of serum HBV RNA levels and HBV RNA levels below the lower limit of detection were analyzed in CHB patients.The correlation between serum HBV RNA levels and the level of serum ALT,AST,qHBsAg,HBeAg and HBV DNA was analyzed.Results Among the 72 patients,12 were HBeAg positive while the rest 60 were HBeAg negative.Age of HBeAg positive patients was younger than that of HBeAg negative patients,while the level of serum AST,qHBsAg and HBV RNA were significant higher than those of HBeAg negative patients(P<0.05).Serum HBV DNA level and the incidence of HBV RNA below the lowest limit of detection in HBeAg positive patients were significantly lower than those of HBeAg negative patients(P<0.05).The results of multivariate linear regression analysis revealed that HBeAg (B=0.837,t=2.634,P=0.010) was a key factor influencing serum level of HBV RNA in CHB patients(P<0.05).It also demonstrated that qHBsAg〔OR=1.682,95%CI(1.055,2.681),P=0.029〕and HBeAg〔OR=3.85,95%CI(1.068,13.880),P=0.039〕were influential factors of the incidence of HBV RNA below the lowest limit of detection.Serum level of HBV RNA in CHB patients was correlated with qHBsAg (rs=0.322,P=0.006) and HBeAg (rs=0.235,P=0.047).Serum level of HBV RNA was positively correlated with qHBsAg(rs=0.848,P<0.001)and HBeAg(rs=0.725,P=0.008)in HBeAg positive patients.Conclusion The level of serum HBV RNA in CHB patients with low HBV DNA level varies according to HBeAg status.HBeAg status contributes to serum HBV RNA level,and both qHBsAg and HBeAg could cause the level of HBV RNA below the lowest limit of detection.
