Pre-exposure prophylaxis (PrEP) based on tenofovir represents a considerably new preventive intervention that has shown to significantly decrease the number of HIV infections while it enables early diagnosis of HIV and other sexually transmitted diseases (STI). In Southern Spain, the target population to receive PrEP are men who have sex with men (MSM) with a history of STI and who pursue high-risk sexual practices regarding the acquisition of HIV, including an elevate number of sex partners, no or inconsistent condom use and the use of specific recreational drugs in the context of sexual activity ("chemsex"). Despite the benefits of PrEP use, it must be taken into consideration that risk compensations that may facilitate the acquisition of other STI may occur, including a higher implementation of risk practices and an increase in the number of partners, which is made easy as various social networks designed for this purpose are available nowadays. In order to better understand the benefit/drawback ratio, accurate data of a population using PrEP under real-life conditions, with densely scheduled follow-up and well-characterized (socio-)demographic parameters, sexual behaviour and STI are warranted.
This is a randomized placebo-controlled study in treated and suppressed HIV-infected individuals aged ≥40 years with either known CVD or 1 CVD risk factor to study the effect of Bempedoic acid (BA) on safety, arterial inflammation as assessed by FDG-PET/CT, lipids, inflammation, immune activation, cardiometabolic indices, and non-calcified plaque (NCP) in the coronary arteries (assessed by coronary CT angiography, CCTA). This trial will be enrolled at UCSF and UCLA. Collaborators at Massachusetts General Hospital (MGH) will serve as the core facility for imaging.
The aim of the trial is to evaluate in ANRS CO6 PRIMO cohort participants if the presence of the MHC B35 (53) Bw4TTC2 genotype favors the control of HIV infection (defined by a viral load (VL) less than 400 cp/mL) after discontinuation of antiretroviral therapy (ART) initiated during primary HIV infection. The trial will be a pilot "proof of concept", one arm, multicenter, nested in the ANRS CO6 PRIMO Cohort, in which the intervention is treatment interruption (of at least 6 months). It is planned to include between 20 and 50 participants.
This study tests strategies for improving PrEP implementation in maternal and child health clinics using an interrupted time series.
Aim: To explore the effectiveness of psychoeducation and problem-solving (Life-steps) on depression and adherence in HIV-infected adolescents. Methods: Forty-two adolescents were randomized into 21 controls and 21 intervention groups. The intervention group was exposed to 5-week sessions of life steps applied by a lay counselor. The PHQ-9 and visual analog scale (VAS) were used to measure the outcomes: depression and adherence. They were applied at baseline, 5-weeks, and 24 weeks post-intervention.
The purpose of this study is to develop and test a serious injection-related injections (SIRI) checklist aimed at increasing evidence-based treatment for rural people who use drugs (PWUD) including innovative, long-acting injectable agents. The central hypothesis is that hospital-based care models can successfully engage rural and Southern (PWUD) in effective addiction treatment and infection prevention. The activities in this study will be foundational to Ending the HIV epidemic in rural states.
This study will evaluate whether a new program will affect how often human immunodeficiency virus (HIV) antiretroviral therapy (ART) prescriptions are filled and whether the program improves the health of people living with HIV.
Integrase-strand-transfer-inhibitors (INSTIs) based regimens have been associated with body weight gain and increase in total body adipose tissue (AT). Whereas there is by now no clear understanding of the mechanisms that induce these changes, we have observed modifications of AT in vitro, in animals models or in vivo in obese patients with raltegravir (RAL) and dolutegravir (DTG) with the presence of increased peri-adipocyte fibrosis and high levels of collagen VI that have been associated with poor metabolic prognoses together with cellular insulin resistance and decreased adiponectin secretion. One major clinical question is whether such AT abnormalities are reversible. Doravirine (DOR), the most recent available Non-Nucleosidic Reverse Transcriptase Inhibitor (NNRTI) drug, has an excellent metabolic profile and as a NNRTI is expected to induce neither changes in fat tissue distribution nor changes in body weight. Tenofovir disoproxil fumarate (TDF) is associated with a protective lipid profile and, unlike tenofovir alafenamide (TAF) which seems to potentiate weight gain in combination with INSTI, has not been associated with weight gain. One major clinical question is whether such AT abnormalities are reversible. Doravirine, the most recent available NNRTI drug, has an excellent metabolic profile and as a NNRTI is expected to induce neither changes in fat tissue distribution nor changes in body weight. Tenofovir DF is associated with a protective lipid profile and, unlike TAF which seems to potentiate weight gain in combination with INSTI, has not been associated with weight gain. We hypothesized that modifications in morphology and function of the adipose tissue in patients with significant weight gain under an INSTI-based regimen could be improved after switching to the triple drug TDF/Emtricitabine/DOR and that fat increase and body weight will be stopped or reversed. This pathogenesis study aimed to evaluate potential changes in adipose tissue after switching from an INSTI-based regimen (Raltegravir or Dolutegravir or Bictegravir) to TDF/Emtricitabine/DOR. Each patient will be evaluated with an adipose tissue biopsy performed before (D0) and after a 48 week switch (W48) from an INSTI-based regimen to the non INSTI-based regimen combining TDF/3TC/Doravirine. With a number of 22 patients at D0, a total of 20 patients with paired adipose tissue biopsies are expected at W48. The antiretroviral therapy with TDF/emtricitabine/Doravirine will be used as routine practice recommends.
This research programme seeks to combine the resources of NHS primary care, with the leading spectroscopic work in low-magnetic fields of the Wilson Group (Nottingham Trent University) to demonstrate the potential for benchtop Nuclear Magnetic Resonance (NMR) spectroscopy in human clinical pathology. This is an instrument assessment study for point of care viability which will also result in enhanced patient care (pending their consent) in blood screenings and metabolic health data.
