Insufficient vaccine coverage and vaccine hesitancy in people living with HIV: A prospective study in outpatient clinics in the Paris region.

Vaccine prevention strategies play a crucial role in the management of people living with HIV (PLWH). The aim of this study was to assess vaccination coverage and identify barriers to vaccine uptake in PLWH in the Paris region. A cross-sectional survey was conducted in PLWH in 16 hospitals in the Paris region.

Striking differences in weight gain after cART initiation depending on early or advanced presentation: results from the ANRS CO4 FHDH cohort.

Background: Many studies have reported weight gain in ART-naive people living with HIV (PWH) initiating an integrase strand-transfer inhibitor-based regimen. We studied the impact of early or advanced presentation and that of individual drugs in PWH initiating combined ART (cART) between 2012 and 2018.

Methods: From the French Hospital Database HIV cohort, we assessed factors associated with a weight gain  ≥10%, weight change after cART initiation or BMI increase  ≥5 kg/m2 up to 30 months.

CD4/CD8 Ratio and the Risk of Kaposi Sarcoma or Non-Hodgkin Lymphoma in the Context of Efficiently Treated Human Immunodeficiency Virus (HIV) Infection: A Collaborative Analysis of 20 European Cohort Studies.

Background: A persistently low CD4/CD8 ratio has been reported to inversely correlate with the risk of non-AIDS defining cancer in people living with human immunodeficiency virus (HIV; PLWH) efficiently treated by combination antiretroviral therapy (cART). We evaluated the impact of the CD4/CD8 ratio on the risk of Kaposi sarcoma (KS) or non-Hodgkin lymphoma (NHL), still among the most frequent cancers in treated PLWH.

Methods: PLWH from the Collaboration of Observational HIV Epidemiological Research Europe (COHERE) were included if they achieved virological control (viral load ≤ 500 copies/mL) within 9 months following cART and without previous KS/LNH diagnosis.

Travel-associated STI amongst HIV and non-HIV infected travellers.

Background: The incidence of sexually transmitted infections (STI) is increasing in Western countries whilst travel plays a major role in STI dissemination worldwide. However, there is no study distinguishing HIV-positive and HIV-negative travellers.

Methods: We retrospectively evaluated the epidemiological, clinical and biological characteristics of the patients diagnosed with a travel-related STI between 2008 and 2016.

Antiretroviral drug reduction in highly experienced HIV-infected patients receiving a multidrug regimen: the ECOVIR study.

Objectives: In a context of life-long therapy, we asked whether it could be possible to reduce the number of antiretroviral drugs without jeopardizing viral suppression.

Methods: ECOVIR was a prospective study aiming to assess whether in patients on combination ART with ≥4 antiretrovirals for ≥24 weeks and virally suppressed for ≥48 weeks, a drug-reduced (DR) regimen could be proposed. The intervention consisted of discontinuing genotypically less susceptible drugs to reach a DR regimen with ≤3 antiretrovirals.

Net emergence of substitutions at position 28 in NS5A of hepatitis C virus genotype 4 in patients failing direct-acting antivirals detected by next-generation sequencing.

More data on resistance of HCV genotype (GT) 3 and 4 to direct-acting antivirals (DAAs) are still needed. Here we investigated the presence of resistance-associated substitutions (RASs) pre- and post-treatment and their emergence under DAAs in HCV GT3- and GT4-infected patients failing DAA regimens by next-generation sequencing (NGS). Sanger sequencing and NGS were performed on NS5B and NS5A in plasma samples prior to and post treatment of 13 patients.

CD4+/CD8+ ratio restoration in long-term treated HIV-1-infected individuals.

Objectives: A persistently low CD4/CD8 ratio despite virological control reflects a higher risk of morbidity in HIV-infected individuals. The objective of the study was to assess the probability and determinants of ratio restoration (≥1) during long-term combined antiretroviral therapy (cART).

Design: Study cohort based on the French Hospital Database on HIV (ANRS CO4).

Determinants of a Low CD4/CD8 Ratio in HIV-1-Infected Individuals Despite Long-term Viral Suppression.

Background: A low CD4/CD8 ratio in human immunodeficiency virus (HIV)-infected individuals despite effective antiretroviral therapy (ART) reflects ongoing immune activation and has been linked to a higher risk of non-AIDS morbidity and mortality. Our aim was to describe the proportion of individuals with a persistent CD4/CD8 ratio <1 despite long-term viral suppression and to determine associated risk factors.

Methods: This cross-sectional study was conducted in 2012 in a single clinical center.

Virological factors associated with outcome of dual maraviroc/raltegravir therapy (ANRS-157 trial).

Objectives: ROCnRAL ANRS-157 was a single-arm study designed to evaluate a switch to a maraviroc (300 mg twice a day) plus raltegravir (400 mg twice a day) regimen in virologically suppressed HIV-1-infected patients (ClinicalTrials.gov: NCT01420523). The aim of this work was to investigate the factors associated with virological failure (VF) (5/44 patients) or virological rebound defined as one viral load (VL) >50 copies/mL or VL >1 copy/mL.

Vitamin D supplementation is associated with reduced immune activation levels in HIV-1-infected patients on suppressive antiretroviral therapy.

Background: A majority of HIV-1-infected patients present a severe deficit in vitamin D, which predicts short-term mortality. Vitamin D is a naturally synthesized hormone, with important immunomodulatory functions. In the general population, its deficit has been associated with increased markers of inflammation.

Comparative impact of antiretroviral drugs on markers of inflammation and immune activation during the first two years of effective therapy for HIV-1 infection: an observational study.

Background: Few studies have compared the impact of different antiretroviral regimens on residual immune activation and inflammation with discordant results. Aim of the study was to investigate the impact of various antiretroviral regimens on markers of immune activation and inflammation during the first two years of effective therapy.

Methods: We studied HIV-infected antiretroviral-naïve patients who began cART with either abacavir/lamivudine or tenofovir/emtricitabine, combined with ritonavir-boosted lopinavir (LPV/r), atazanavir (ATV/r) or efavirenz (EFV).

Detection of HIV-1 RNA in seminal plasma samples from treated patients with undetectable HIV-1 RNA in blood plasma on a 2002-2011 survey.

Objectives: To estimate the frequency of detectable seminal HIV-1 viral load in men with repeatedly undetectable blood viral load, in the recent past years and over a 10-year period (2002-2011) in a large cohort of HIV-1-infected men from couples requesting assisted reproduction technologies. We also searched for an association between HIV-1 RNA seminal viral load, HIV-1 RNA plasma viral load measured by ultrasensitive assay, and blood HIV-1 DNA in a subgroup of 98 patients.

Methods: Three hundred and four HIV-1 infected men have provided 628 paired blood and semen samples.

Raltegravir as functional monotherapy leads to virological failure and drug resistance in highly treatment-experienced HIV-infected patients.

The objective of this study was to evaluate the development of resistance to raltegravir (RAL) in patients with viraemia between 40 and 400 copies/ml. All HIV-1-infected patients with multidrug-resistant virus, plasma HIV-1 RNA >1000 copies/ml and starting RAL were enrolled in this observational study and followed up until week 48. Sixty-seven patients with median plasma HIV-1 RNA at 4.
