Response from Dr. Sherer

This difficult situation is very common. It does illustrate the need for people who have just been found to have HIV and who are starting HIV medications to make the most of that opportunity. HIV is very unforgiving. You have done good hard work to get to and maintain sobriety for 4 years, so you are used to swimming upstream.
In general, I would suggest that you talk to your doctor about this question. He or she knows much more about the specifics of your case, and they are critical to making the best choices at this point, i.e. your treatment history, your resistance test and viral load results, drug toxicities, etc. I will make some suggestions in any event, and you can talk to your doctor about them.
There are two new protease inhibitors - tipranavir and TMC-114 - that have good activity against viruses that are resistant to most current PIs. In the studies that lead to their approval by the FDA (or to expanded access, in the case of TMC-114), 1/3 of patients were able to have good virologic control with their use.
There are also some clinical trials of other new agents for people who are heavily treatment experienced that may be available to you and your doctor, depending on where you live. You can use the NIH hotline to find such trials in your area - 1-800 - TRIALSA.
It might be useful to get a phenotype resistance test in addition to the more common genotype test. Often, for example, your physician can identify one or more of the current NRTIs such as tenfovir, abacavir, or didanosine, to which your virus has partial susceptibility.
Finally, there is evidence, even in someone like yourself who is resistant to most or all current drugs, that staying on some ART is better than being on none at all - better in terms of longer survival and less rapid disease progression. For example, when patients continue on one or more drugs of the NRTI class like 3TC, AZT, or DDI, they have less rapid declines in their T cells and less rapid increases in their viral loads than those who stop all drugs.
Also, remember that when people with HIV become ill, it is usually due to opportunistic infections, some of which can be prevented by taking simple medications. The two common forms of 'OI preventive therapy or prophylaxis' are bactrim (TMP-SMX) one double strength tablet once daily (which prevents pneumocystis pneumonia) and azithromycin two tablets weekly (which prevents MAC or mycobacterium avium complex infection). You should still be taking both of these.
I suggest that you talk to you doctor about your status, your questions, and this response.
