HIV-1-RNA and total HIV-1-DNA loads in the genital compartment in men receiving dolutegravir- versus darunavir-based combined ART (cART) regimens during primary HIV infection.

For the first time, to the best of our knowledge, we showed that a dolutegravir-based regimen initiated as soon as PHI reduces HIV-RNA and HIV-DNA with no difference compared with a control group receiving a darunavir-based regimen. Although the viral purge in semen seems longer after treatment in PHI than CHI, due to high viral loads, early dolutegravir-based treatment initiation permits a major decay of both viral particles and infected cells in semen, efficiently reducing the high risk of transmission during PHI.
