Lipoatrophy and Truvada
Jul 1, 2012
What are my drug options if I am experiencing lipoatrophy (particularly arm fat reduction) and my current medication is Truvada and Isentress? (I have been on this combination for 16 months and it is my first HIV medication) - is there anther drug combination that might be an option?
Response from Dr. Pierone
The strongest association with development of lipoatrophy is with nucleoside analogue reverse transcriptase inhibitors (NRTIs). Truvada is a combination of tenofovir (Viread) and emtricitabine (Emtriva) and is less likely to produce lipoatrophy as compared with older NRTIs. However, lipoatrophy may still occur with Truvada.
There is interest in nuke-sparing regimens for patients with lipoatrophy to see if stopping this class of medications might eventually lead to improvement of the fat loss. There are some studies that show protease inhibitor-based antiretroviral treatment may protect against lipoatrophy to some extent. But the downside is that protease inhibitors have been linked to lipohypertrophy, elevated cholesterol, and increased risk of cardiovascular complications.
So what about nuke and protease inhibitor-sparing therapy for reversal or prevention of lipoatrophy? The combination of Isentress and Intelence would be an example of such a regimen. Unfortunately we have no studies of this strategy available as of yet.
I hope this information helps and best of luck!
