ABSTRACT
Objective To investigate the correlation of the 1896 and 1899 mutations of hepatitis B virus (HBV)with the conversion of e antigen in serum and the progression of the disease. Methods 238 serum samples from the patients with HBsAg positive for over six months and HBV-DNA copy number > 5.0 × 102 IU/mL were collected,and the sequence analysis was used to analyze the nucleotide sequences of the 1896 and 1899 sites in the pre-C region of HBV. At the same time,the relevant clinical data and the expressions of HBeAg were collected,followed by Spearman correlation analysis and chi square test with SPSS 20.0. Results Both 1896 and 1899 sites in the pre-C region of HBV were mutated,and the base G was A,which was closely related to the expression of e antigen(P<0.05). Both G1896A and G1899A promoted the e antigen serological conversion ,and the e antigen serological conversion of G1899A was higher than that of G1896A. G1899A was associated with HBV related disease progression (correlation coefficient 0.280,P < 0.05),especially with the incurrence of HCC. Conclusions G1896A and G1899A in the pre-C region of HBV can promote the serological conversion of e antigen.
