A good combination?
Mar 24, 2004
Is Viread plus ddI plus Sustiva a good combination? I'm sensitive to these three but resistant to AZT and 3TC. I take Viread, Sustiva, and Kaletra now with VL less than 50, but I am growing wary of the high triglycerides, cholesterol and now possible glucose intolerance. I was wondering if it would be wise for the substitution of ddI for Kaletra. Thanks. Terry

I do not think I'd recommend the kind of swap you are proposing. That you have AZT and 3TC resistance raises the possibility that you may have decreased response to ddI (even if the genotype does not indicate this). Additionally, your Kaletra may be doing quite a bit of the heavy lifting as far as keeping your viral load below 50. Those are bid shoes to fill for ddI especially if your off treatment viral load is high.
An alternative would be to continue the Viread and Sustiva and change the Kaletra to atazanavir (Reyataz) 300 mg a day plus ritonavir (Norvir) 100 mg a day. There are some complicated drug interactions here but this may be a good combo for you as atazanavir even with ritonavir does not seem to have as much of an effect on lipids and glucose as many other protease inhibitors.
Another Kaletra substitute could be to ritonavir boosted saquinavir (Fortovase) (a PI wil less metabolic effects that it is given credit for). This would involve more pills, however.
