Participating country : FRANCE

Primary objective : Comparing the kinetic of HIV-RNA decay in blood plasma and in seminal plasma in patients starting a triple combination regimen with dolutegravir + tenofovir DF (TDF) + emtricitabine (FTC) at the time of PHI.

Secondary objectives :

• Comparison of HIV-1 RNA level in plasma (threshold 20 and 1 copies/ml) and in seminal plasma (threshold 60 copies/ml) at each visit D0, W2, W4, W8, W12, W24, W36, W48
• To assess the frequency of intermittent shedding in seminal plasma once virological suppression has been achieved and until W48
• Evolution of cellular HIV-1 DNA level in PBMC and in non-sperm cells between D0 and W48
• Comparison of dolutegravir concentration in blood plasma and seminal plasma
• Study of risk factors associated with viral persistence of HIV-RNA in the seminal plasma
• Analysis by deep sequencing of the viral population (quasi-species) in both compartments (blood plasma and seminal plasma) before virological suppression has been achieved (i.e. at D0 and W12)

Inclusion criteria :

• Patients diagnosed at the time of primary HIV infection (PHI) (i) a negative or indeterminate HIV ELISA associated with a positive antigenemia or plasma HIV RNA, (ii) a western blot profile compatible with ongoing seroconversion (incomplete western blot with absence of antibodies to pol proteins (p34, p68)) or (iii) an initially negative test for HIV antibodies followed within 3 months by a positive HIV serology
• Treatment including dolutegravir (DTG 50mg) + tenofovir/emtricitabine (TDF/FTC 245 mg/200 mg) initiated by the referee physician within a maximum of 15 days after diagnosis of PHI
• Genotypic sensitivity to TDF, FTC and DTG
• Patient with medical care insurance

Exclusion criteria :

• Chronic infection
• Infection or co-infection with HIV-2

Study treatment : Dolutegravir and tenofovir/emtricitabine Number of subjets : 20 patients (exploratory study)
