OBJECTIVES: To assess the association between immune-activation (IA), immune-senescence (IS), inflammation biomarkers and renal function measured by estimated glomerular function rate (eGFR) at inclusion and its evolution over a 3-years follow-up in HIV-infected patients with undetectable viral load. DESIGN: The CIADIS (Chronic Immune Activation anD Senescence) sub-study consecutively included patients between October 2011 and May 2013 enrolled in the ANRS CO3 Aquitaine observational cohort...

BACKGROUND: Cancer is a growing problem in persons living with HIV infection (PLWH) and hepatitis C virus (HCV) coinfection could play an additional role in carcinogenesis. Herein, all cancers in an HIV-mono and HIV/HCV-coinfected cohort were evaluated and compared to identify any differences between these two populations. METHODS: A retrospective cohort study was conducted including all cancers in PLWH between 1993 and 2014. Cancers were classified in two groups, AIDS-defining cancer (ADC) and non AIDS-defining cancer (NADC)...

BACKGROUND: Viral coinfections might contribute to the increased immune activation and inflammation that persist in ART-treated HIV-1 patients. We investigated whether the HCV co-infection contributes to such alterations by impairing the pDC IFNα/TLR7 pathway in a highly homogeneous group of ART-treated HIV-1-HCV co-infected patients. METHODS: Twenty nine HIV-1-infected patients with fully suppressive ART were included, fifteen of whom being HCV co-infected with mild to moderate fibrosis and matched for their HIV-1 disease, and thirteen control healthy donors...

OBJECTIVE: We suggested cervical cancer screening strategies for women living with HIV (WLHIV) by comparing their precancer risks to general population women, and then compared our suggestions to current CDC guidelines. DESIGN: We compared risks of biopsy-confirmed cervical high-grade squamous intraepithelial neoplasia or worse (bHSIL+), calculated among WLHIV in the Women's Interagency HIV Study, to "risk benchmarks" for specific management strategies in the general population...

The MTN-020/ASPIRE trial evaluated the safety and effectiveness of the dapivirine vaginal ring for prevention of HIV-1 infection among African women. A nested qualitative component was conducted at 6 of 15 study sites in Uganda, Malawi, Zimbabwe and South Africa to evaluate acceptability of and adherence to the ring. Qualitative study participants (n = 214) were interviewed with one of 3 modalities: single in-depth interview, up to 3 serial interviews, or an exit Focus Group Discussion. Using semi-structured guides administered in local languages, 280 interviews were audio-recorded, transcribed, translated, coded and analyzed...

OBJECTIVES: In this study, we first assessed costs associated with the use of ART in an infectious diseases University Hospital Clinic, we secondly evaluated characteristics associated with these costs, and finally simulated the impact on the overall ART budget of switching 1- and 2-line regimens to less costly regimens (as effective and well-tolerated). DESIGN: Cohort analysis including PLHIV ≥ 18 years on ART to estimate ART costs during 2014. METHODS: This study was conducted in the Bichat-Claude Bernard University Hospital Clinic in Paris, France, where 4,501 PLHIV consulted in 2014...

OBJECTIVE: A recent meta-analysis suggested that opioid substitution therapy (OST) increased uptake of anti-retroviral treatment (ART) and HIV viral suppression. We modelled whether OST could improve the HIV prevention benefit achieved by ART amongst people who inject drugs (PWID). METHODS: We modelled how introducing OST could improve the coverage of ART across a PWID population for different baseline ART coverage levels. Using existing data on how yearly HIV-transmission risk is related to HIV plasma viral load, changes in the level of viral suppression across the population were used to project the relative reduction in yearly HIV-transmission risk achieved by ART, with or without OST, compared to if there was no ART - defined here as the prevention effectiveness of ART...

OBJECTIVES: Nitrite inhalants (poppers) are commonly used recreational drugs among men who have sex with men (MSM) and were previously associated with elevated rates of high-risk sexual behavior, HIV and HHV-8 seroconversion, and transient immunosuppressive effects in experimental models. Whether long-term popper use is associated with cancer risk among MSM in the HAART era is unclear. DESIGN: Prospective cohort study of cancer risk in 3223 HIV-infected and -uninfected MSM in the Multicenter AIDS Cohort Study from 1996-2010...

Most new HIV infections occur via sexual routes. The induction of protective anti-HIV antibodies in genital mucosa is an important step towards reducing HIV transmission. Mucosal anti-HIV antibodies may play a dual role by either protecting against HIV transmission or facilitating it. Protective properties against HIV of mucosal IgGs and IgAs exhibiting neutralizing or antibody dependent cell-mediated cytotoxicity (ADCC) activities have been described in highly exposed seronegative individuals (HESN). Conversely, some IgGs may facilitate the crossing of HIV free particles through epithelial barriers by transcytosis...

OBJECTIVES: Completion rates for HIV post-exposure prophylaxis (PEP) are often low. We investigated the adherence and safety of dolutegravir (DTG 50 mg daily) with tenofovir disoproxil fumarate 300 mg/emtricitabine 200 mg (TDF-FTC) as 3-drug PEP in gay and bisexual men (GBM). DESIGN: Open-label, single-arm study at 3 sexual health clinics and 2 emergency departments in Australia. METHODS: One hundred HIV-uninfected GBM requiring PEP received DTG plus TDF-FTC for 28 days...

OBJECTIVE: We compiled the largest dataset of seroconverter cohorts to date from 25 countries across Africa, North America, Europe, and SE/E. Asia to simultaneously estimate transition rates between CD4 stages and death, in ART-naive HIV-1 infected individuals. DESIGN: A hidden Markov model incorporating a misclassification matrix was used to represent natural short-term fluctuations and measurement errors in CD4 counts. Covariates were included to estimate the transition rates and survival probabilities for each subgroup...

OBJECTIVE: To determine the long term effects of vorinostat on safety and virological parameters in HIV-infected individuals on suppressive antiretroviral therapy (ART). DESIGN: Prospective longitudinal observational extended follow up of 20 HIV-infected individuals on ART previously enrolled in a clinical trial of daily vorinostat 400 mg for 14 days. Extended follow up included visits at 6, 12, 18 and 24 months post enrolment in the initial clinical trial. METHODS: Cell-associated unspliced (CA-US) HIV RNA, total HIV DNA and plasma HIV RNA were quantified by PCR and, CD4+ and CD8+ T cells quantified by flow cytometry...

OBJECTIVES: HIV-1-infected persons spontaneously controlling viremia without treatment (SCV) are rare. Gender and race effects on prevalence and outcome are poorly defined, and it is unclear whether SCV qualitatively or quantitatively differs from typical infection. These issues are examined. DESIGN: Medical records of 46 524 persons receiving outpatient care for HIV-1 infection were reviewed. Of these, 29 811 had adequate viremia testing for SCV screening. METHODS: SCV was defined as ≥3 consecutive plasma viremia measurements <50 RNA copies/mL spanning ≥1 year without treatment...
