CROI 2015: Similar Fat Gain Seen with Different Antiretroviral Regimens [VIDEO]

People starting antiretroviral therapy containing raltegravir (Isentress) and those starting boosted atazanavir (Reyataz) or darunavir (Prezista) experienced significant increases in both abdominal and limb fat, with no evidence of greater fat gains among those taking HIV protease inhibitors, according to findings presented at the 2015 Conference on Retroviruses and Opportunistic Infections (CROI) last week in Seattle.

"We saw a significant increase in peripheral and central fat with all the regimens," McComsey said, describing results from the ACTG 5260s substudy at a CROI press conference. "We used to think protease inhibitors were associated with central fat accumulation, but here even an integrase inhibitor made patients gain as much fat."

She added, however, that people who started antiretroviral therapy before they experienced advanced immune suppression gained less fat, suggesting that this is another reason to start people on treatment "right away, regardless of CD4 count."
