Acceptability determinants of a proposal to reduce antiretroviral treatment to an oral two-drug regimen among patients living with HIV and physicians in France.

An oral two-drug regimen (O2DR) in the form of a once-a-day single tablet is now recommended for treatment switching and treatment initiation for HIV. In clinical care, the process of treatment change refers to adaptation issues, both individual and within the care relationship. The study aim is to present the determinants involved in the acceptability of switching to O2DR in the PROBI (Patient-Reported Outcomes BItherapy) qualitative study.

Limited Impact of Cannabidiol on Health-related Quality of Life of People With Long-term Controlled HIV: A Double-blind, Randomized, Controlled Trial.

Background: People with HIV (PWH) with undetectable HIV viral load still have an impaired health-related quality of life (HRQoL). Cannabidiol (CBD) is a nonintoxicating cannabis-derived cannabinoid that holds promise for the treatment of many ailments. In the present study, we tested whether oral CBD-rich medication could significantly improve PWH's HRQoL.

Patient-Reported Outcomes After Switching to a 2-Drug Regimen of Fixed-Dose Combination Dolutegravir/Lamivudine: 48-Week Results from the SALSA Study.

Patient-reported outcomes (PROs) facilitate communication between patients and providers, enhancing patient-centered care. We report PROs for virologically suppressed people living with HIV-1 who switched to dolutegravir/lamivudine (DTG/3TC) or continued their 3- or 4-drug current antiretroviral regimen (CAR) in the phase 3 SALSA study. Secondary endpoints included change from baseline in HIV Treatment Satisfaction Questionnaire (status version; HIVTSQs) and HIV Symptom Distress Module (HIV-SDM) at Weeks 4, 24, and 48.

Increased incidence of diabetes in people living with HIV treated with first-line integrase strand transfer inhibitors: A French multicentre retrospective study.

Introduction: Prevention of cardiovascular disease is a major issue in the current management of people living with HIV. Concern is growing about the metabolic impact of integrase strand transfer inhibitors (INSTIs), which could lead to an increased risk of diabetes, but the data are conflicting. This is an updated version of our previous analysis, with longer follow-up and new molecules.

Distinct evolution of SARS-CoV-2 Omicron XBB and BA.2.86/JN.1 lineages combining increased fitness and antibody evasion.

The unceasing circulation of SARS-CoV-2 leads to the continuous emergence of novel viral sublineages. Here, we isolate and characterize XBB.1, XBB.

Use of genotypic HIV DNA testing: a DELPHI-type consensus.

Objectives: As many disparities in the clinical use of HIV DNA sequencing are observed, a DELPHI-type consensus was initiated in France to homogenize use, techniques and interpretation of results.

Methods: Based on a literature review and clinical experience, a steering committee (SC) of eight virologists and one infectious disease specialist formulated statements. Statements were submitted to an independent and anonymous electronic vote of virologists and HIV clinicians in France, between October 2022 and December 2022.

High fusion and cytopathy of SARS-CoV-2 variant B.1.640.1.

SARS-CoV-2 variants with undetermined properties have emerged intermittently throughout the COVID-19 pandemic. Some variants possess unique phenotypes and mutations which allow further characterization of viral evolution and Spike functions. Around 1,100 cases of the B.

Distinct evolution of SARS-CoV-2 Omicron XBB and BA.2.86/JN.1 lineages combining increased fitness and antibody evasion.

The unceasing circulation of SARS-CoV-2 leads to the continuous emergence of novel viral sublineages. Here, we isolated and characterized XBB.1, XBB.

HIV-1 treatment timing shapes the human intestinal memory B-cell repertoire to commensal bacteria.

HIV-1 infection causes severe alterations of gut mucosa, microbiota and immune system, which can be curbed by early antiretroviral therapy. Here, we investigate how treatment timing affects intestinal memory B-cell and plasmablast repertoires of HIV-1-infected humans. We show that only class-switched memory B cells markedly differ between subjects treated during the acute and chronic phases of infection.

Modeling the kinetics of the neutralizing antibody response against SARS-CoV-2 variants after several administrations of Bnt162b2.

Because SARS-CoV-2 constantly mutates to escape from the immune response, there is a reduction of neutralizing capacity of antibodies initially targeting the historical strain against emerging Variants of Concern (VoC)s. That is why the measure of the protection conferred by vaccination cannot solely rely on the antibody levels, but also requires to measure their neutralization capacity. Here we used a mathematical model to follow the humoral response in 26 individuals that received up to three vaccination doses of Bnt162b2 vaccine, and for whom both anti-S IgG and neutralization capacity was measured longitudinally against all main VoCs.

Country of birth is associated with discrepancies in the prescription of two-drug regimens in successfully treated people with HIV in France.

Objectives: We aimed to examine the association of the country of birth and the other patients' characteristics with the prescription of two-drug regimens (2DRs) in virally suppressed people with HIV (PWH) in France.

Design: Observational study conducted from the national Dat'AIDS prospectively collected database.

Methods: We included all adults who were actively in care on 31 December 2020 in 26 French centers, with an HIV plasma viral load (pVL) <50 copies/ml for at least 6 months while on antiretroviral therapy (ART).

Anti-V1/V3-glycan broadly HIV-1 neutralizing antibodies in a post-treatment controller.

HIV-1 broadly neutralizing antibodies (bNAbs) can decrease viremia but are usually unable to counteract autologous viruses escaping the antibody pressure. Nonetheless, bNAbs may contribute to natural HIV-1 control in individuals off antiretroviral therapy (ART). Here, we describe a bNAb B cell lineage elicited in a post-treatment controller (PTC) that exhibits broad seroneutralization and show that a representative antibody from this lineage, EPTC112, targets a quaternary epitope in the glycan-V3 loop supersite of the HIV-1 envelope glycoprotein.

Country of birth is associated with antiretroviral therapy choice in treatment-naive persons with HIV in France.

Objectives: We aimed to describe factors associated with the choice of first antiretroviral therapy (ART) in persons with HIV (PWH) in France, included the country of birth, as well as the time to undetectable viral load and treatment discontinuation.

Design: Observational study conducted from the national Dat'AIDS prospectively collected database.

Methods: We included all adults who started their first ART between 01 January 2014 and 31 December 2020, with a pretherapeutic plasma viral load (pVL) at least 400 copies/ml.

Weight gain following the single substitution of tenofovir disoproxil fumarate by tenofovir alafenamide in HIV-infected people from the French Dat'AIDS cohort: A propensity score-matched analysis.

Objectives: To minimize confounding factors, we aimed to describe the changes in weight and body mass index (BMI) following the single substitution of tenofovir disoproxil fumarate (TDF) by tenofovir alafenamide (TAF) in people living with HIV (PLWH).

Methods: We designed a retrospective study in a large French cohort. We included all HIV-suppressed adults under TDF + emtricitabine + rilpivirine or elvitegravir/cobistat, who experienced a first switch from TDF to TAF, while other antiretrovirals remained unchanged (Switch group).
