Abstract:
Objective To explore the related factors of hepatitis B virus(HBV) drug resistance and their clinical significance . Methods The retrospective analysis was performed on the dinical data in 153 cases of CHB in our hospital during 2011-2013 .The 8 viral drug resistance loci of 4 known nucleosides analogues lamivudine ,adefovir ester ,entecavir and telbivudine were performed the direct sequencing by using the double DNA end termination method(Sanger method);the related clinical factors of drug‐resist‐ant virus genotypes were statistically analyzed and the correlation between prognosis and drug resistance was analyzed .Results A‐mong 153 patients with CHB ,47 cases(29 .8% ) appeared virus genotype drug‐resistant ,the common sites were 204M‐I(18 cases) , 204M‐V(8 cases) ,followed by 181A‐T(10 cases) ,181A‐V(5 cases) ,then 180L‐M (14 cases) .The proportion of viral drug resist‐ance in the patients with family history ,HBeAg positive ,using the nucleotide analogues in the past and the baseline ALT≥5 times was significantly increased ,the incidence rates were 38 .8% ,34 .8% ,34 .6% and 50 .0% respectively .The multivariable COX re‐gression found that HBV‐DNA genetic drug resistance increased the risk of progression to cirrhosis of the liver ,the OR value was 4 .704(95% CI:1 .199 -18 .454) .Conclusion the Sanger method for direct sequencing is reliable and accurate method of HBV‐DNA genotype drug resistance .The proportion of viral drug resistance in the patients with a family history of hepatitis B ,HBeAg positive ,using nucleotide analogues and baseline ALT≥5 times is significantly increased;HBV‐DNA genotype drug resistance also increases the risk of progression to cirrhosis of the liver .
