    Hi everyone! I am caring for a 73yo male who was diagnosed with HIV in 1992, AIDS dx in 1994. I have good records on him since 2014, very spotty records before that. I know that 2008-2013 he was taking FTC/TDF+ATV/r, and then had an episode of renal lithiasis that caused ARF and his GFR never fully recovered, but has stayed in the 30-40 range since then. At this time he was switched to his current regimen of FTC 200mg QOD, ATV/r QD and AZT 300mg BID. I would love to get him switched to a STR with a higher barrier to resistance, or even just 2 pills QD would be easier. His only other medications are losartan and atorvastatin. 

    I don't know his initial VL but the first I can find from 2008 was 45700, CD4 nadir was 140, now hovers around 500. He has been virally suppressed since 2009, and genotype at this time showed no NRTI resistance predicted. Stanford mutation database results attached but widespread NNRTI and PI resistance predicted. According to the genotype, the ATV/r shouldn't be working, but it is. I'm thinking he would be a good candidate for DTG/3TC. Your thoughts? Is there anything else I should think of? 

    Thanks in advance for your input,

    Deb

    Great Case,

    I would be cautious with a two-active drug regimen because he has a K103N, and L100I which would make me closely monitor a NRTI, NNRTI regimen. The DTG should help with suppressing NRTI mutations, but a three-active drug regimen would be my recommendation in this case.

    Your thoughts?

    Hi Dr. Deborah: If he hasn't been exposed to INSTI I wouldn't be afraid of using Bictarvy; his GFR has been over 30 and he is already in  a highly toxic treatment for his  kidneys because ATVr after long Is even worst than TDF itself.  ATVr has been also strongly associated with kidney stones and the AZT for sure starts to worry us due to metabolic toxicity  and lypoystrophy.

    Other posible option if he hasn't failed to INSTI could be DOVATO because he has been  suppressed for long and even if he has 184V (he could have for sure  because he seems to be a very experienced patient)  will be enough to keep him suppressed

    There is enough evidence published at the moment showing that both strategies  are safe. 

    You have to expect some increase in creatinine with both Bicyarvy and Dovato. 

    In fact darunavir plus ritonavir would be a better option than ATVr in a patient with renal impairment.  I wouldn't use DRV cobicistat. It's

    I'm surprised that he was left on boosted ATV, which is strongly associated with kidney stones and renal insufficiency (not to mention his PI resistance).  And of course, there's virtually never a role for AZT anymore.  I agree with others that Biktarvy would be a much better regimen. In this case, the sooner the better.
