Abstract
BACKGROUND Total human immunodeficiency virus (HIV) DNA and integrated HIV DNA are widely used markers of HIV persistence. Droplet digital polymerase chain reaction (ddPCR) can be used for absolute quantification without needing a standard curve. Here, we developed duplex ddPCR assays to detect and quantify total HIV DNA and integrated HIV DNA. METHODS The limit of detection, dynamic ranges, sensitivity, and reproducibility were evaluated by plasmid constructs containing both the HIV long terminal repeat (LTR) and human CD3 gene (for total HIV DNA) and ACH-2 cells (for integrated HIV DNA). Forty-two cases on stable suppressive antiretroviral therapy (ART) were assayed in total HIV DNA and integrated HIV DNA. Correlation coefficient analysis was performed on the data related to DNA copies and cluster of differentiation 4 positive (CD4 + ) T-cell counts, CD8 + T-cell counts and CD4/CD8 T-cell ratio, respectively. The assay linear dynamic range and lower limit of detection (LLOD) were also assessed. RESULTS The assay could detect the presence of HIV-1 copies 100% at concentrations of 6.3 copies/reaction, and the estimated LLOD of the ddPCR assay was 4.4 HIV DNA copies/reaction (95% confidence intervals [CI]: 3.6-6.5 copies/reaction) with linearity over a 5-log 10 -unit range in total HIV DNA assay. For the integrated HIV DNA assay, the LLOD was 8.0 copies/reaction (95% CI: 5.8-16.6 copies/reaction) with linearity over a 3-log 10 -unit range. Total HIV DNA in CD4 + T cells was positively associated with integrated HIV DNA ( r = 0.76, P <0.0001). Meanwhile, both total HIV DNA and integrated HIV DNA in CD4 + T cells were inversely correlated with the ratio of CD4/CD8 but positively correlated with the CD8 + T-cell counts. CONCLUSIONS This ddPCR assay can quantify total HIV DNA and integrated HIV DNA efficiently with robustness and sensitivity. It can be readily adapted for measuring HIV DNA with non-B clades, and it could be beneficial for testing in clinical trials.

Abstract
BACKGROUND Decreasing medication burden with raltegravir plus lamivudine in virologically suppressed persons with HIV (PWH) maintained efficacy and was well tolerated at 24 weeks, but more comprehensive data over longer follow-up are required. METHODS Prospective 48 week extension phase of the raltegravir plus lamivudine arm from a previous 24 week pilot randomized clinical trial in which virologically suppressed PWH were randomized 2:1 to switch to fixed-dose combination 150 mg lamivudine/300 mg raltegravir twice daily or to continue therapy. In this 48 week extension phase, raltegravir was dosed at 1200 mg/day and lamivudine 300 mg/day. Primary outcome was the proportion of PWH with treatment failure at Week 48. Secondary outcomes were changes in ultrasensitive plasma HIV RNA, HIV DNA in CD4 cells, serum IL-6, ultrasensitive C-reactive protein and sCD14, body composition, sleep quality, quality of life and adverse effects. RESULTS Between May 2018 and June 2019, 33 PWH were enrolled. One participant experienced virological failure without resistance mutations and re-achieved sustained virological suppression without therapy discontinuation, and two others discontinued therapy due to adverse effects. Treatment failure was 9% (95% CI 2%-24%) and 3% (95% CI 0%-17%) in the ITT and on-treatment populations. There were significant changes between baseline and Week 48 in serum cytokines but not in other secondary outcomes. CONCLUSIONS Switching to raltegravir and lamivudine in PWH with virological suppression maintains efficacy and is well tolerated. This maintenance regimen might be a cost-effective option for PWH at risk of drug-drug interactions or needing to avoid specific toxicities of certain antiretroviral drugs or their negative impact on comorbidities.

Four days/week antiretroviral maintenance strategy (ANRS 170 QUATUOR): substudies of reservoirs and ultrasensitive drug resistance. J Antimicrob Chemother 2023:7146011.

Abstract
BACKGROUND In a 4 days/week (4/7 days) maintenance strategy (ANRS-170 QUATUOR trial), the virological impact of an intermittent strategy was assessed by ultrasensitive virological analyses of reservoirs and resistance. METHODS HIV-1 total DNA, ultra-sensitive plasma viral load (USpVL) and semen VL were measured in the first 121 participants. Sanger and ultra-deep sequencing (UDS) were performed on the HIV-1 genome (Illumina technology) according to the ANRS consensus. A generalized estimation equation with a Poisson distribution was used to compare changes in the proportion of residual viraemia, detectable semen HIV RNA and HIV DNA within and between the two groups over time. RESULTS The proportion of participants with residual viraemia at Day 0 (D0) and Week 48 (W48) was 16.7% and 25.0% in the 4/7 days group and 22.4% and 29.7% in the 7/7 days group, respectively (+8.3% versus +7.3%, P = 0.971). The proportion of detectable DNA (>40 copies/106 cells) at D0 and W48 was 53.7% and 57.4% in the 4/7 days group and 56.1% and 51.8% in the 7/7 days group, respectively (+3.7% versus -4.3%, P = 0.358). Semen HIV RNA was detectable (≥100 copies/mL) in 2.2% of participants at D0 and 4.5% at W48 in the 4/7 days group versus 6.1% and 9.1% in the 7/7 days group, respectively (+2.3% versus +3.0%, P = 0.743). Emerging resistance at failure was more frequent in the 4/7 days group detected by Sanger sequencing: 3/6 participants versus 1/4 in the 7/7 days group, and similar with the UDS assay: 5/6 versus 4/4, respectively. CONCLUSIONS These findings support the potency of a 4/7 days maintenance strategy on virological suppression at the reservoirs and emergent resistance level, including minority variants.

Abstract
Les innovations pour traiter l’infection par le virus de l’immunodéficience humaine (VIH) n’ont pas cessé depuis les premières monothérapies et, en 1996, les premières trithérapies. L’une d’elles vient d’être validée par l’essai ANRS QUATUOR. Elle consiste à prendre deux fois moins de médicaments, en rendant le traitement intermittent. À la demande des patients non adhérents à sa prescription standard, Jacques Leibowitch a encadré cette pratique dès 2002, en s’appuyant sur une étude transgressant le dogme de l’adhésion stricte au traitement quotidien. Ce concept de traitement à temps partiel provenait des travaux du groupe d’Anthony Fauci, mais il le revisitera pour le pousser à son apogée avec la cohorte Iccarre. Son intention strictement thérapeutique s’inscrivit initialement dans le cadre du protocole de soin Iccarre qui, en 2020, comptait 96 patients, majoritairement en réduction médicamenteuse de 70 % grâce à l’ultra-intermittence thérapeutique. Il a posé les bases de l’essai contrôlé QUATUOR dont le résultat, récemment publié, montre la non infériorité des traitements intermittents à 4 jours/7 de médicaments par rapport au traitement standard.

Abstract
Memory T cells include T memory stem cells (TSCM) and central memory T cells (TCM). Compared with effector memory T cells (TEM) and effector T cells (TEFF), they have better durability and anti-tumor immunity. Recent studies have shown that although TSCM has excellent self-renewal ability and versatility, if it is often exposed to antigens and inflammatory signals, TSCM will behave as a variety of inhibitory receptors such as PD-1, TIM-3 and LAG-3 expression, and metabolic changes from oxidative phosphorylation to glycolysis. These changes can lead to the exhaustion of T cells. Cumulative evidence in animal experiments shows that it is the least differentiated cell in the memory T lymphocyte system and is a central participant in many physiological and pathological processes in humans. It has a good clinical application prospect, so it is more and more important to study the factors affecting the formation of TSCM. This article summarizes and prospects the phenotypic and functional characteristics of TSCM, the regulation mechanism of formation, and its application in treatment of clinical diseases.

Much attention has been paid to a newly discovered subset of memory T (TM) cells-stem cell-like memory T (TSCM) cells for their high self-renewal ability, multi-differentiation potential and long-term effector function in adoptive therapy against tumors. Despite their application in cancer therapy, an excess of TSCM cells also contributes to the persistence of autoimmune diseases for their immune memory and HIV infection as a long-lived HIV reservoir. Signaling pathways Wnt, AMPK/mTOR and NF-κB are key determinants for TM cell generation, maintenance and proinflammatory effect. In this review, we focus on the phenotypic and functional characteristics of TSCM cells and discuss their role in autoimmune diseases and HIV-1 chronic infection. Also, we explore the potential mechanism and signaling pathways involved in immune memory and look into the future therapy strategies of targeting long-lived TM cells to suppress pathogenic immune memory.

A single lentivector DNA based immunization contains a late heterologous SIVmac251 mucosal challenge infection. Vaccine 2020; 38:3729-3739. [PMID: 32278522 DOI: 10.1016/j.vaccine.2020.03.053] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2019] [Revised: 03/18/2020] [Accepted: 03/28/2020] [Indexed: 12/16/2022]
Abstract
Variety of conventional vaccine strategies tested against HIV-1 have failed to induce protection against HIV acquisition or durable control of viremia. Therefore, innovative strategies that can induce long lasting protective immunity against HIV chronic infection are needed. Recently, we developed an integration-defective HIV lentiDNA vaccine that undergoes a single cycle of replication in target cells in which most viral antigens are produced. A single immunization with such lentiDNA induced long-lasting T-cell and modest antibody responses in cynomolgus macaques. Here eighteen months after this single immunization, all animals were subjected to repeated low dose intra-rectal challenges with a heterologous pathogenic SIVmac251 isolate. Although the viral set point in SIVmac-infected cynomolgus is commonly lower than that seen in Indian rhesus macaques, the vaccinated group of macaques displayed a two log reduction of peak of viremia followed by a progressive and sustained control of virus replication relative to control animals. This antiviral control correlated with antigen-specific CD4+ and CD8+ T cells with high capacity of recall responses comprising effector and central memory T cells but also memory T cell precursors. This is the first description of SIV control in NHP model infected at 18 months following a single immunization with a non-integrative single cycle lentiDNA HIV vaccine. While not delivering sterilizing immunity, our single immunization strategy with a single-cycle lentivector DNA vaccine appears to provide an interesting and safe vaccine platform that warrants further exploration.
