Here we describe a case of lamivudine and entecavir resistant chronic hepatitis B, treated with western medicine plus traditional korean medicine combination therapy. We administered Injinchunggan-Tang(茵蔯淸肝湯), a traditional Korean herb remedy, with entecavir to a 45-year-old chronic hepatitis B patient who didn"t have achieved HBV-DNA suppression, in spite of 18 month lamivudine mono therapy and 14 month entecavir mono therapy. HBV-DNA decreased more than one thousandth from 98,100 IU/mL to 53 IU/mL just in 23 days, and resultingly it seems that the combination therapy could be very potent, at least to some chronic hepatitis B patients.
