I've had HIV for 14 years and been taking drugs for about 7 years. Pretty much since they came out. Started out with zerit/crixivan/epivir/acylovir and had to switch the crixivan for viracept after about six month due to kidney stones.
I recently moved to south florida and had to change doctor. This new doctor wants to switch everything around, and to be honest it's stressing me out. I appreciate his explaination that he wants to forstall problems, but he wants to put me on viramune, epivir and that new one tourvir or whatever it's called.
I've had great results so far. Another doctor I see was dubious that I should all of a sudden switch. I'm having anxiety attacks over this which is not usual for me.
Response from Dr. Aberg
I am assuming that by saying you have had great results on zerit (d4T, stavudine), epivir (3TC, lamivudine) and viracept (NFV, nelfinavir)that you mean your HIV viral load in your blood has been undetectable. That is very good results after essentially 7 years on the same regimen. I do understand your concerns. Why change medicines if there are no problems with the current regimen?
There is no right answer here. Your new doctor is most likely worried about the metabolic complications seen long term in patients on therapy. These metabolic abnormalities such as high lipids, fat loss, fat accumulation and increased blood sugar appear to be more associated with some of the nucleosides and protease inhibitors. Additionally, some studies suggest that zerit may be more associated with lactic acidosis and mitochondrial toxicity which in turn, may have an association with these other metabolic abnormalities. Having said that, not everybody taking protease inhibitors develops these abnormailities nor everyone on zerit develops side effects. Your new doctor has recommended swicthing to a non-nucleoside drug called viramune (NVP, nevirapine). Swicthing to NVP has shown to improve the lipid and glucose abnormalities but has not shown to be effective for the fat loss and fat accumulation. Patients usually maintain their CD4 and HIV viral load benefits meaning the CD4 count stays up and the viral load remains suppressed. Tenofovir is a new drug called a nucleotide and works similar to zerit. The long term side effects of tenofovir are unknown but so far, studies look very promising.
I personally do not switch my patients unless they are having problems tolerating the medicines (e.g. diarrhea with viracept) or developing complications. It sounds like you have no complaints. I think it is totally reasonable for you to stay on your current regimen. Over time, you may want or need to switch, but it sounds like this is not what you want to do at this time. It may be that your new doctor doesn't perceive your anxiety. I am sure s/he thinks this strategy is best in the long run but there is no data on individuals like yourself who have been on therapy greater than 5 years without any metabolic complications to show that switching from a PI to a NNRTI will be better long term in preventing these occurrences. Also your new doctor may think that taking less pills would be of interest to you.
You should go back and discuss this with your doctor. If you cannot seem to come upon a mutual agreement, then I would suggest you find another healthcare provider. My guess is that s/he is concerned about your well-being and did not realize how anxiety-provoking this recommendation is.
