History of Changes


Eligible HIV-infected patients with clinically evident lipoatrophy despite treatment with efavirenz and fixed-dose combination of thymidine nucleoside analogues will be informed and asked to enroll in the study; will be randomized (1:1) into two branches, A: EFV + Fixed combinations of analogue tenofovir + emtricitabine.B (experimental): LPV/r + combination of correspondent analogues. The main variable is the evaluation of the absolute change in limb fat mass at 24 months from baseline in both groups.
