Summary

In view of the prolongation of patients living with HIV's life expectancy, the question of optimization of ART, which is still a life-long treatment, becomes central. While most patients achieve virological success, their treatments often need to be optimized in order to limit adverse events, drugs interactions and to improve adherence. The switch to dual regimen strategies represent one of the approaches for treatment optimization. Circulating HIV-1 resistant variants can be archived in viral reservoirs, where they can persist for an unknown duration and reemerge in case of therapeutic selective pressure. There is a need to assess the dynamic of archived Drug resistance associated mutations (DRAMs) clearance in cell-associated HIV DNA after a long period of virological control, in the perspective of ARVs recycling. The investigators postulate that it could be interesting in the future to recycle ARV drugs (that where classified as "resistant" in the past) in subsequent regimen. The question is particularly important for 3TC/FTC for subsequent new regimen and for the use of dual regimen (disappearance of M184V). Thus, the investigators propose a retrospective, longitudinal analysis on blood-cell-associated HIV-1 DNA samples in order to investigate by Sanger and Ultra Deep Sequencing the dynamics of decay and persistence of DNA HIV-1 variants harboring key drug resistance-associated mutations to NRTIs, in particular M184V, in patients with sustained virological control for at least 5 years under effective ART.

Conditions

• HIV-1-infection

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Genotypic Resistance Test	A Genotypic Resistance Test by Sanger sequencing will be done after the period of virological suppression. * If M184V is still present no additional test will be performed. * If M184V is absent, we will go back in the previous samples (one per year) to determine the time point where the mutation has been cleared by sanger and UDS sequencing.
