Abstract
BACKGROUND This was a substudy of a Phase IV, randomized clinical trial (ClinicalTrials.gov identifier: NCT04295460) aiming to compare the activity of dolutegravir/lamivudine versus dolutegravir plus tenofovir alafenamide/emtricitabine (DTG + TAF/FTC) in the male genital tract. METHODS Participants were asymptomatic adults without sexually transmitted diseases, treatment-naive people living with HIV (PLWH), with CD4+ T cell counts >200 cells/mm3 and plasma HIV-1-RNA levels >5000 and <500 000 copies/mL, randomized (1:1) to DTG + TAF/FTC or dolutegravir/lamivudine. Blood plasma (BP) and seminal plasma (SP) were collected at baseline and Weeks 4, 8, 12 and 24. HIV-1-RNA was measured in BP and SP using the Cobas 6800 system (Roche Diagnostics) with a lower detection limit of 20 copies/mL. The primary efficacy endpoint was the proportion of subjects with undetectable SP HIV-1-RNA at Week 12 by intention-to-treat analysis. RESULTS Fifteen participants in the DTG + TAF/FTC and 16 in the dolutegravir/lamivudine arms were analysed, with basal SP viral load of 4.81 (4.30-5.43) and 4.76 (4.09-5.23), P = 0.469, respectively. At Week 12, only one participant in each treatment arm had a detectable SP HIV-1-RNA (DTG + TAF/FTC, 141 copies/mL; dolutegravir/lamivudine, 61 copies/mL). Based on the estimated means, there was no significant difference in the decay of HIV-1-RNA in both BP and SP over time between the two arms of treatment (F = 0.452, P = 0.662, and F = 1.147, P = 0.185, respectively). CONCLUSIONS After 12 weeks of treatment, there were no differences in the percentage of undetectable SP HIV-1-RNA in naive PLWH who started dolutegravir/lamivudine compared with DTG + TAF/FTC.

Abstract
Acquired immunodeficiency syndrome (AIDS), caused by the human immunodeficiency virus (HIV), has become a heavy burden of disease and an important public health problem in the world. Although current antiretroviral therapy (ART) is effective at suppressing the virus in the blood, HIV still remains in two different types of reservoirs-the latently infected cells (represented by CD4+ T cells) and the tissues containing those cells, which may block access to ART, HIV-neutralizing antibodies and latency-reversing agents. The latter is the focus of our review, as blood viral load drops below detectable levels after ART, a deeper and more systematic understanding of the HIV tissue reservoirs is imperative. In this review, we take the lymphoid system (including lymph nodes, gut-associated lymphoid tissue, spleen and bone marrow), nervous system, respiratory system, reproductive system (divided into male and female), urinary system as the order, focusing on the particularity and importance of each tissue in HIV infection, the infection target cell types of each tissue, the specific infection situation of each tissue quantified by HIV DNA or HIV RNA and the evidence of compartmentalization and pharmacokinetics. In summary, we found that the present state of HIV in different tissues has both similarities and differences. In the future, the therapeutic principle we need to follow is to respect the discrepancy on the basis of grasping the commonality. The measures taken to completely eliminate the virus in the whole body cannot be generalized. It is necessary to formulate personalized treatment strategies according to the different characteristics of the HIV in the various tissues, so as to realize the prospect of curing AIDS as soon as possible.

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.

Abstract
BACKGROUND Dolutegravir is a widespread integrase strand-transfer inhibitor (INSTI) recommended for treatment of primary HIV infection (PHI). PHI is a high-risk stage for sexual transmission because of the high viral load in semen. Yet dolutegravir concentrations in semen are lower than in blood during chronic treatment. OBJECTIVES To compare the kinetics of HIV-RNA and total HIV-DNA in the genital compartment in subjects receiving either tenofovir/emtricitabine/dolutegravir or tenofovir/emtricitabine/darunavir/cobicistat as a first-line combined ART (cART) at the time of PHI. PATIENTS AND METHODS Eighteen subjects receiving tenofovir/emtricitabine/dolutegravir and 19 receiving tenofovir/emtricitabine/darunavir/cobicistat enrolled in the ANRS169 OPTIPRIM-2 trial participated in the genital substudy. RESULTS Between week (W) 0 and W2 HIV-RNA in seminal plasma (SP) decreased by 1 log10 copies/mL. Undetectable SP HIV-RNA was achieved in similar proportions between the two regimens at each timepoint. Overall, eight patients still presented detectable HIV-RNA or HIV-DNA in semen at W48; 15.4% and 28.6% presented detectable HIV-RNA and 9.1% and 14.3% presented detectable HIV-DNA in dolutegravir- and darunavir-based cART groups, respectively, with no significant difference. CONCLUSIONS 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.

Abstract
Objective To provide insight on viral kinetics and genetic diversity of HIV in seminal plasma at baseline and 1 month after initiating antiretroviral therapy (ART). Patients and methods Blood and seminal samples from patients with newly diagnosed HIV were obtained before ART initiation (T0) and 1 month after ART initiation (T1). HIV env genetic diversity was studied using deep sequencing Nextera and V3 chemistry in a MiSeq Illumina platform. The number of viral quasispecies (5% cut-off) and Shannon Index were used to analyse diversity. Results Forty-seven ART-naive patients were recruited between September 2016 and November 2018. At enrolment, the number of quasispecies in blood (median 4 (IQR 2–5)) was lower than in the seminal compartment (median 6, (IQR 4–8)) (p<0.01); the Shannon Index was also higher (p<0.001) in the seminal compartment than in blood (1.77 vs 0.64). At T1, for the 13 patients with detectable HIV in both blood/seminal plasma, viral diversity remained higher (p=0.139) in seminal plasma (median 2 (IQR 1–4.5)) than in blood (median 1 (IQR 1–1.5)) Integrase inhibitors (INI)-based regimens achieved higher levels of undetectability and led more frequently to lower variability (p<0.001) than protease inhibitors (PI) or non-nucleoside reverse transcriptase inhibitors (NNRTI). Conclusion We provide here further evidence of a larger genetic diversity in seminal plasma, both at diagnosis and short term after ART initiation. Our results strengthen previous findings on HIV diversity in seminal plasma. In addition, INIs decrease variability more rapidly than PI and NNRTI in both blood and seminal plasma.

Abstract
The male genital tract (MGT) is the target of a number of viral infections that can have deleterious consequences at the individual, offspring, and population levels. These consequences include infertility, cancers of male organs, transmission to the embryo/fetal development abnormalities, and sexual dissemination of major viral pathogens such as human immunodeficiency virus (HIV) and hepatitis B virus. Lately, two emerging viruses, Zika and Ebola, have additionally revealed that the human MGT can constitute a reservoir for viruses cleared from peripheral circulation by the immune system, leading to their sexual transmission by cured men. This represents a concern for future epidemics and further underlines the need for a better understanding of the interplay between viruses and the MGT. We review here how viruses, from ancient viruses that integrated the germline during evolution through old viruses (e.g., papillomaviruses originating from Neanderthals) and more modern sexually transmitted infections (e.g., simian zoonotic HIV) to emerging viruses (e.g., Ebola and Zika) take advantage of genital tract colonization for horizontal dissemination, viral persistence, vertical transmission, and endogenization. The MGT immune responses to viruses and the impact of these infections are discussed. We summarize the latest data regarding the sources of viruses in semen and the complex role of this body fluid in sexual transmission. Finally, we introduce key animal findings that are relevant for our understanding of viral infection and persistence in the human MGT and suggest future research directions.

Abstract
Introduction:
The prevention of transmission of HIV infection is based on the regular and correct use of condom and studies on transmission rates are generally based on the self-report of condom use.
However, consistent data on different population suggest that this often leads to overreporting possibly due to social desirability. In addition, self-report of condom use does not consider improper use or breakage.
Methods:
Vaginal biomarkers were proposed to detect exposure to semen and among these detection of chromosome Y DNA (Yc) appeared promising in different research settings.
Here, we searched for Yc in vaginal swabs of 33 Italian women, engaged in a regular heterosexual relationship with a HIV serodiscordant partner and reporting a regular use of condom during sexual intercourses.
Results & Discussion:
In 10 (30.3%) women Yc was detected, especially if the infected partner was male and if the couple did not have sons. This is confirmed in Italian heterosexual women and is already demonstrated in other populations: behavioural counselling is not always a valid tool and the self-reported use of condom is not fully reliable.
Conclusion:
Further studies could help in the future to individuate more effective preventive strategies for both HIV and sexually transmitted infections.
