A 6-Month Interruption of Antiretroviral Therapy Improves Adipose Tissue Function in HIV-Infected Patients: The ANRS EP29 Lipostop Study

Abstract

A 6-month ART interruption markedly improved adipose tissue functions, although fat distribution did not visibly change. Stavudine and zidovudine were associated with marked inflammation, which improved when these drugs were withdrawn; they also had a negative effect on differentiation and mitochondrial status. PIs were also associated with altered adipocyte differentiation and mitochondrial status. These data clearly show the detrimental effect of antiretroviral drugs, in particular thymidine analogues, on adipose tissue and argue for switch strategies sparing these drugs.
