Response from Dr. McGovern

Zeffix (lamivudine) is active against both HIV and HBV. So since we do not usually treat HIV with only one drug, we do not recommend Zeffix if you only want to treat HBV.

However, if your HIV has been suppressed all this time, then you are not at risk for resistance right now. That is good news. Perhaps your HIV RNA level was so low, that one drug was enough to suppress you.

There are several key questions: for your hepatitis B, are you E antigen positive? If so, did you seroconvert? (eg, did you lose E antigen and gain E antibody). If so, I would treat for at least another 12 months after seroconversion.

If you were E antigen negative, I would continue to treat indefinitely because I would expect your HBV infection to come back again if you stop your medication.

There are some doctors who would recommend staying on HIV/HBV medications from now on, regardless of how good your CD4 count is (and it is great)...One possible combination would be Atripla (tenofovir, emtricitabine and efavirenz all rolled into one pill; the first two medications have activity against both HIV and HBV).

Other considerations you can discuss with your doctor are your liver disease stage and how well you are tolerating medications.
