RESUMO
Objective To investigate the relationship between the serum markers and genotype with viral load in chronic hepati-tis B in order to improve the level of clinical treatment.Methods 819 patients with chronic hepatitis B in our hospital from April 2010 to April 2013were selected as the study subjects and performed the genotyping.The hepatitis B virus(HBV)DNA level was detected by using real-time fluorescence PCR.Results Among the 819 cases of positive HBsAg,357 cases were positive HBV-DNA,accounting for 43.59%;HBeAg(+)accounted for 90.11%;in the positive modes of serum markers and viral load,most of positive cases were HBsAg,HBeAg,HBcAb and HBsAg,HBeAb,HBcAb,accounting for 88.52%;HBV genotyping had B,C,BC mixed types and unclassified type,the logrithm levels of viral DNA were(7.187 ±1.668),(7.184 ±1.558),(7.208 ±1.447)and (7.313±1.505),there was no statistically significant difference among them(P >0.05).Conclusion The virus gene in the patients with chronic hepatitis B is dominated by type C,in which serum markers HBeAg and HBV-DNA viral load have the lose correlated, the infected virus genotype has the low correlation with the viral load.
