Body Composition Sub-study of the D2EFT Trial

Consenting participants will be randomised within the main D2EFT protocol to receive either ritonavir-boosted darunavir plus two nucleosides or dolutegravir plus two predetermined nucleosides (lamivudine or emtricitabine) or ritonavir-boosted darunavir plus dolutegravir. Enrolment into the sub-study is voluntary and not a requirement for enrolment into D2EFT. Parameters relevant to this study including demographics, arm of randomised ART, smoking status, body habitus and fasting lipid parameters and resting blood pressure at required time points will be collected as part of the main D2EFT study. Sub-study specific assessments performed at baseline and at weeks 48 and 96 include clinical and laboratory assessments, sample collection and dual-energy X-ray absorptiometry (DXA)-assessed whole-body composition. Consenting participants will have blood for storage collected at weeks 0, 48 and 96. The specimens will be used for future studies into treatment of HIV infection and immunity.
