Abstract: Adefovir dipivoxil(ADV),an oral nucleotide analogue,remains as one of the major antiviral agents in the treatment of chronic hepatitis B(CHB) in China. However,long-term therapy with ADV may lead to hepatitis B virus(HBV) drug-resistant mutations. The signature mutations associated with ADV resistance are rtA181V and rtN236T. The newly-identified ADV primary resistant mutations are rtA181S,rtE218G and rtN236V. In addition,some other mutations including rtA181T,rtV214A, rtQ215H/P/S,rtL217R/P,rtI233V,and rtN238T/D/H remain contradictory,and these mutations need to be further identified.
