Background: The human immunodeficiency virus type 1 (HIV-1) cannot be eradicated even with suppressive antiretroviral therapy because its retrotranscribed genome integrates into the DNA of host cells, creating a long-term reservoir. Quantification of total HIV-1 DNA in peripheral blood is a biomarker of this reservoir that can predict progression of the infection, treatment response, and HIV-1-related complications. A deeper understanding of the reservoir may help develop a cures.

Background: No study has compared the virological and immunological status of young people with perinatally-acquired HIV infection (P-HIV) with that of people with HIV adulthood (A-HIV) having a similar duration of infection.

Methods: 5 French cohorts of P-HIV and A-HIV patients with a known date of HIV-infection and receiving antiretroviral treatment (ART), were used to compare the following proportions of: virological failure (VF) defined as plasma HIV RNA ≥ 50 copies/mL, CD4 cell percentages and CD4:CD8 ratios, at the time of the most recent visit since 2012. The analysis was stratified on time since infection, and multivariate models were adjusted for demographics and treatment history.

Background: Pre-diabetes mellitus (DM) is associated with proteinuria, a risk factor for chronic kidney disease. While people with human immunodeficiency virus (HIV; PWH) have a higher risk of proteinuria than people without HIV (PWOH), it is unknown whether incident proteinuria differs by HIV serostatus among prediabetic persons.

Methods: The urine protein-to-creatinine ratio was measured at semiannual visits among men in the Multicenter AIDS Cohort Study since April 2006.

Background: A previous study showed an association between CD4 T-cell count decline in people with human immunodeficiency virus infection (PWH) with viral suppression and an increased risk of severe morbid conditions. We aimed to assess the risk of CD4 T-cell count decline (hereafter, CD4 decline), determine associated factors, and evaluate the association of this decline with the risk of severe morbid conditions (cardiovascular disease and cancer) or death.

Methods: From the Agence Nationale de Recherches sur le SIDA et les hépatites virales (ANRS) CO4 French Hospital Database on HIV cohort, we selected PWH >18 years old who had been followed up for ≥2 years after viral suppression following the initiation of combination antiretroviral therapy (cART) between 2006 and 2018.

Objectives: Our objective was to determine whether antiretroviral drugs (ARVs) were used according to the European AIDS Clinical Society (EACS) guidelines for people with HIV/hepatitis C virus (HCV) coinfection treated with direct-acting antivirals (DAAs) between 30 November 2014 and 31 December 2019 in the pan-European EuroSIDA study.

Methods: At each publication date of the EACS guidelines, plus 3 and 6 months, we calculated the number of people receiving DAAs with potential and actual ARV contraindications ('red shading' in the EACS guidelines). We used logistic regression to investigate factors associated with using contraindicated ARVs.

Article Synopsis
  • Down syndrome (DS) is linked to trisomy of human chromosome 21 and features intellectual disability, studied through two mouse models with extra gene copies.
  • RNA analysis showed different gene expression patterns tied to chromatin and synaptic functions in each model, while a large-scale protein interaction study found numerous connections to intellectual disability-related genes.
  • Key proteins from chromosome 21 were found at crucial synaptic sites, revealing potential links between Down syndrome, autism risk genes, and other brain disorders like Alzheimer's disease.

Here we report a case of Epstein-Barr virus (EBV)-associated smooth muscle tumor (SMT) of the peripheral nerve in a young man seropositive for human immunodeficiency virus (HIV). Initially, the lesion was clinically and radiologically confused with a schwannoma of the forearm's posterior interosseous nerve. The diagnosis was corrected by histological examination, which revealed a well-defined tumor consisting of eosinophilic spindle cells, positive for α-smooth muscle actin on immunohistochemistry and positive for EBV-encoded early RNA (EBER) on in situ hybridization.

Introduction: Attendance at face-to-face courses is low in the 2nd and 3rd years of medical school in France, possibly because of a lack of interactivity. We used Moodle (an open-source course management system) to introduce blended learning on Infectious Diseases and Microbiology through interactive quizzes and sessions of online-based continuous assessment. This pre-post observational study assessed changes in students' attendance and student as well as teacher satisfaction.

Objectives: Anal cancer, usually driven by an oncogenic Human Papillomavirus, remains a leading cause of morbidity in men who have sex with men (MSM) living with HIV, despite combined antiretroviral therapy. Various recommendations advocate to perform regular examination and proctologist-performed samples to anticipate this risk and treat locally before cancer occurrence, an efficient strategy which has the drawback of requiring the proctologist's availability. This study evaluates the acceptability, feasibility, and efficiency of self-performed samples to screen for HPV-infection and HPV-related anal dysplasia among MSM living with HIV followed in Hôtel-Dieu Hospital.
