ABSTRACT
Objective To explore the correlation of serum HBV-DNA load,transaminase(ALT)and total bile acid (TBA)levels with hepatitis B virus (HBV)infection patterns to assess HBV infectivity.Methods The fluorescent quantitative PCR was used to detect serum HBV-DNA in 308 patients with HBV infection.ELISA was adopted to detect the HBV markers.The continuous mo-nitoring method was adopted to detect serum ALT and the cycling enzymatic method was adopted to detect serum TBA.Results The HBV-DNA content and serum ALT level had staitstical differences among the 3 infection patterns of HBsAb,HBeAg and HB-cAb positive,HBsAg,HBsAb,and HBcAb positive and 1,5 positive (P 0.05).Conclusion Serum HBV-DNA content and ALT activity have the correlation with the different HBV infection patterns,which could reflect the HBV replication and the infectivity intensity in some extent.
