| Main Objective: To explore changes in limb fat assessed by DEXA measurements, after the substitution of the Zidovudine + Lamivudine NRTI-backbone by Truvada (TDF+FTC) versus maintaining the original Zidovudine-containing regimen without any change, through 48 wk.;Primary end point(s): Objective assessment: of change from baseline in limb fat at Week 48 as measured by DEXA.;Secondary Objective: • To explore changes in the mtDNA/nDNA ratio in PBMC in each study group. • To assess the proportion of patients with HIV RNA < 400 and < 50 copies/mL during the follow-up weeks (weeks 12-72) in each group. • To assess changes in CD4+ cell count in each group throughout the study. • To monitor the safety profile of both treatment arms, recording all adverse events that may appear during the study. • To define the resistance profile in case of virological failure. • To assess the changes in hemoglobin and hematocrit levels in each group. • To assess metabolic parameters in each group (total cholesterol, HDLc, LDLc, triglycerides, lactic acid). • To assess patient adherence | — |
