OBJECTIVE: HIV-1 infection is associated with an increased cardiovascular disease (CVD) risk. Advanced glycation end products (AGEs) are formed as stable markers of glycemic and oxidative stress. Skin autofluorescence (SAF) as marker of accumulated AGEs is increased and predictive of CVD events in diabetes mellitus, chronic kidney disease (CKD) and pre-existing CVD. We determined SAF levels in HIV-1 infected patients, testing the hypothesis that SAF predicts CVD events in HIV infection...

Despite extensive investigations, we still do not fully understand the dynamics of the total body HIV reservoir and how sub-reservoirs in various compartments relate to one another. Studies using macaque models are enlightening but eradication strategies will still need to be tested in humans. To take the next steps in understanding and eradicating HIV reservoirs throughout the body, we propose to develop a "peri-mortem translational research model" of HIV-infected individuals (called 'The Last Gift'), which is similar to existing models in cancer research...

OBJECTIVE: Tenofovir (TDF) affects bone health and is widely used in pregnancy but data are limited on the effects of TDF exposure in utero. We examined the association between duration of in utero TDF exposure and linear growth in HIV-exposed, uninfected (HEU) infants. DESIGN: A prospective cohort of pregnant women initiating TDF-containing regimens at primary care services in Cape Town, South Africa were enrolled and followed with their breastfeeding infants through 12 months postpartum...

OBJECTIVE: HIV-1 escape from cytotoxic T-lymphocytes (CTL) results in the accumulation of HLA-associated mutations in the viral genome. To understand the contribution of early escape to disease progression, this study investigated the evolution and pathogenic implications of CTL escape in a cohort followed from infection for five years. METHODS: Viral loads and CD4+ counts were monitored in 78 subtype C infected individuals from onset of infection until CD4+ decline to <350 cells/μl or five years post-infection...

OBJECTIVE: To report the real-life results of sorafenib use in a cohort of HIV-infected patients with hepatocellular carcinoma (HCC). METHODS: The GEHEP-002 cohort ( ID: NCT02785835) has recruited 302 HCC cases diagnosed in HIV-infected patients from 32 centers from Spain. RIS-HEP12 study included 44 (14%) cases that have received at least one dose of sorafenib. The overall survival after the start of treatment (OSaT) was the main efficacy outcome...

OBJECTIVE: To identify relationships between insulin resistance (IR) and mitochondrial respiration in perinatally HIV-infected (pHIV) youth. DESIGN: Case-control study METHODS:: Mitochondrial respiration was assessed in pHIV youth in Tanner stages 2-5, 25 youth with IR (IR+) and 50 without IR (IR-) who were enrolled in the Pediatric HIV/AIDS Cohort Study (PHACS). IR was defined as a Homeostatic Model of Assessment for Insulin Resistance (HOMA-IR) value ≥4.0. A novel, high-throughput oximetry method was used to evaluate cellular respiration in peripheral blood mononuclear cells...

OBJECTIVE: To describe the effect of antiretroviral therapy (ART) and HIV-related factors on high-risk human papillomavirus (HR-HPV) and high-grade cervical intraepithelial neoplasia lesions (CIN2+) among women living with HIV/AIDS (WLHA) in sub-Saharan Africa. DESIGN: Prospective cohort of WLHA in Ouagadougou, Burkina Faso (BF) and Johannesburg, South Africa (SA). Recruitment was stratified by ART status. METHODS: At baseline and endline (median 16 months), cervical samples and biopsies were analyzed for HPV genotyping (InnoLiPA) and by histology...

OBJECTIVE: To better understand the epidemiology of tuberculosis (TB)/HIV co-infection in the European Union (EU) and European Economic Area (EEA) for planning of prevention and control measures. DESIGN: Analysis of surveillance data. METHODS: We performed an analysis of the 2014 TB and AIDS data to assess the burden of TB/HIV co-infection and we applied multivariable logistic regression to evaluate predictors for co-infection. RESULTS: Twenty-one of 31 EU/EEA countries reported HIV testing results for 64...

OBJECTIVE: HIV-1 reservoirs are the major hurdle to virus clearance in cART-treated patients. An approach to eradicating HIV-1 involves reversing latency in cART-treated patients in order to make latent cells visible to the host immune system. Stimulation of patient cell cultures with LRAs ex vivo results in heterogeneous responses among HIV-infected patients. Determinants of this heterogeneity are unknown and consequently, important to determine. DESIGN AND METHODS: Here, we grouped and retrospectively analyzed the data from our two recent HIV-1 reactivation studies to investigate the role of the HIV-1 reservoir size in the reactivation capacity by LRAs in ex vivo cultures of CD8-depleted PBMCs isolated from 54 cART-treated patients and of resting CD4 T cells isolated from 30 cART-treated patients...

OBJECTIVE: To analyze the influence of LILRA3 and the genetic LILRA3 deletion on transmission and clinical course of HIV infection. DESIGN: Case and control study. METHODS: LILRA3 genotypes were determined by polymerase chain reaction. HIV patients were categorized into short-term progressors, normal progressors and long-term non-progressors according to the clinical course. Functional studies were performed using real-time PCR, intracellular flow cytometry and ELISA...

HIV-1 infection is associated with substantial damage to the gastrointestinal (GI) tract resulting in structural impairment of the epithelial barrier and a disruption of intestinal homeostasis. The accompanying translocation of microbial products and potentially microbes themselves from the lumen into systemic circulation has been linked to immune activation, inflammation, and HIV-1 disease progression. The importance of microbial translocation in the setting of HIV-1 infection has led to a recent focus on understanding how the communities of microbes that make up the intestinal microbiome are altered during HIV-1 infection and how they interact with mucosal immune cells to contribute to inflammation...

OBJECTIVE: To quantify the space-time dimensions of human mobility in relationship to the risk of HIV acquisition. METHODS: We used data from the population cohort located in a high HIV-prevalence, rural population in KwaZulu-Natal, South Africa (2000 - 2014). We geolocated 8,006 migration events (representing 1,028,782 km travelled) for 17,743 individuals (≥15 years of age) who were HIV-negative at baseline and followed-up these individuals for HIV acquisition (70,395 person-years)...

OBJECTIVE: Dolutegravir (DGV) is one of the preferred antiretroviral agents in first line cART. Though considered a well-tolerated drug, we aimed to determine the actual rate, timing, and detailed motivation of stopping DGV in a real life clinical setting. DESIGN: a cohort study including all patients that started DGV in two HIV treatment centers in the Netherlands. METHODS: All cART-naïve and cART-experienced patients who had started DGV were identified from the institutional HIV-databases...

OBJECTIVE: To explore the effect of depression and anxiety on adherence to antiretroviral therapy (ART) among men who have sex with men (MSM) with newly diagnosed HIV infections. DESIGN: We conducted a prospective study of Chinese MSM with newly diagnosed HIV infections. METHODS: The Hospital Anxiety and Depression Scale (HADS) was used to measure depression and anxiety at baseline, 6 and 12 months, separately. ART adherence was self-reported once every three months ("perfect" or no missing dose in the past three months vs...

OBJECTIVE: To investigate the toxicity and activity against HIV of 5-hydroxytyrosol (5-HT) as a potential microbicide. DESIGN: The anti-HIV-1 activity of 5-HT, a polyphenolic compound, was tested against wild-type HIV-1 and viral clones resistant to NRTIs, NNRTIs, PIs and INIs. Besides, its activity against founder viruses, different viral subtypes and potential synergy with TDF, 3TC and FTC was also tested. 5-HT toxicity was evaluated in vivo in rabbit vaginal mucosa...

OBJECTIVE: Liver disease markers have been associated with mortality in HIV-infected individuals, in the modern era of effective antiretroviral therapy. Our objective was to determine which markers are most predictive of mortality in HIV-monoinfected and HIV/HCV-coinfected persons. RESEARCH DESIGN AND METHODS: We measured serum albumin, total protein, calculated globulin, aspartate transaminase (AST), and alanine transaminase (ALT) in 193 HIV/HCV-coinfected and 720 HIV-monoinfected persons in the study of Fat Redistribution and Metabolic Change in HIV Infection...
