Correlations of Serum Markers of Hepatitis B Virus,HBV DNA Load and Liver Function / 华中科技大学学报(医学版)

ABSTRACT

Objective To investigate the correlations of serum markers of hepatitis B virus,HBV DNA load and liver function indexes[alanine aminotransferase(ALT)and aspartate transaminase(AST)]in the peripheral blood.Methods Clinical data of 483 patients who were diagnosed with chronic hepatitis B and treated between March 2014 and March 2016 in Tongji hospital were retrospectively analyzed.The serum markers of hepatitis B virus were quantitatively detected by chemiluminescent microparticle immunoassay.Serum HBV DNA load was measured by real-time fluorescence quantitative PCR,and ALT and AST by continuous ultraviolet monitoring.Results There was no correlation between the HBsAg content and HBV DNA load or the rates of abnormal ALT(>41 U/L)and abnormal AST(>35 U/L)(P>0.05).The HBeAg content was not correlated with HBV DNA load and the rates of abnormal ALT(P>0.05),but weakly with the rate of abnormal AST(r=0.21,P0.05),it was weakly related to HBV DNA load and the rates of abnormal AST(r=0.16,P<0.05;r=0.19,P<0.01).The anti-HBc content had weak correlations with HBV DNA load,the rates of abnormal ALT and abnormal AST(r=0.25,P<0.01;r=0.29,P<0.01;r=0.29,P<0.01).The logarithm value of HBV DNA load was weakly positively correlated with ALT and AST(r=0.24;r=0.29).Conclusion Quantitative detection of both serum markers and the DNA of hepatitis B virus can complement each other,and when combined with detection of liver function indexes,it will help understand the damage of liver tissue.
