Abstract:
Objective:To investigate the comparative study of serum hepatitis B virus (HBV) large protein (HBV-LP) , HBV-DNA, and Pre S1 antigen (Pre S1-Ag) detection in the evaluation of serum HBV replication in patients with chronic hepatitis B.
Methods:A total of 482 patients infected with chronic hepatitis B virus (CHB) were enrolled and the serums were collected in a hospital of Hefei city in Anhui province from June 2013 to March 2015. The serum HBV-LP, HBV markers(HBV-M) and Pre S1-Ag were detected using ELISA, and HBV-DNA were quantified using quantitative real-time PCR. The positive detection rate difference of HBV-DNA, HBV-LP and Pre S1-Ag were compared, the correlation between the logarithm of HBV-DNA copies number and the absorbance value of HBV-LP was analyzed using Spearman rank correlation.
Results:The positive rates of HBV DNA, HBV-LP, and Pre S1-Ag were 67.22% (324/482), 73.86% (356/482), and 37.34% (180/482), respectively (P<0.01). The positive rates of the three markers were 54.57% (185/339), 64.90% (220/339), and 27.73% (94/339), respectively, in 339 HBeAg-negative CHB patients (P<0.01). In HBeAg negative patients, the positive rate of HBV-LP in 185 cases of HBV-DNA positive samples was 90.81% (168/185), which was higher than that of Pre S1-Ag with rate of 39.46% (73/185) (P<0.01).The positive rate of HBV-LP was 33.77% (52/154) in 154 cases of patients with negative HBV-DNA whose positive rate was higher than Pre S1-Ag with positive rate of 13.64% (21/154)(P<0.01). The positive rates of HBV-DNA, HBV-LP and Pre S1-Ag in HBsAg, HBeAg and HBcAb positive groups were 97.04% (131/135), 94.81% (128/135), and 60.00% (81/135), (P<0.01); The positive rates of three indexes of HBsAg, HBeAb, HBcAb positive group were 53.74% (122/227), 63.88% (145/227), and 27.31% (62/227); The positive rates of three indexes of HBsAg and HBcAb positive group were 55.79% (53/95), 67.37% (64/95), and 28.42% (27/95) (P<0.01). The absorbance value of HBV-LP was positively related with the logarithm of HBV-DNA copies number (Spearman rank correlation coefficient was 0.908, P<0.01).
Conclusion:There was a good correlation between HBV-LP and HBV-DNA load value, and could be used as an effective complement for the detection of HBV-DNA and HBV-M. Compared with Pre S1-Ag.
