Filter by:The goal of this observational study is to determine the incidence and spectrum of opportunistic infections among Chinese HIV/AIDS patients at this stage, to find intervention targets, to construct an early warning prediction model, and to give an individualized program with integrated immune function to obtain salvage opportunities for patients.The main questions it aims to answer are: - Describe the populations and characteristics of pathogenic microorganisms involved in HIV co-infection, map the spatial and temporal changes in the infection system of pathogenic microorganisms, and evaluate their impact on disease regression. - Explore the mechanism of interaction between pathogenic microorganisms and host autoimmune deficiencies. - Discover early warning and predictive markers and immunological indicators of pathogenic microorganisms, and explore new technologies and programs to reduce the mortality rate of infection.
This study aims to assess the efficacy and safety of pembrolizumab in immunocompromised patients with progressive multifocal leukoencephalopathy (PML). This phase II, multicenter, single-arm study includes patients with an underlying cause of immunosuppression hardly reversible, i.e. not the patients with HIV nor those receiving biologics for chronic inflammatory diseases. Patients will receive intravenous pembrolizumab (2 mg/kg, maximum 200 mg) at month 0, 1 and 2 (total of three doses). The primary endpoint will be achieving at least one negative result of JCV viral load in cerebrospinal fluid (CSF) within the M0 to M3 period.
The goal of this study is to test the effectiveness of ADELANTE on viral suppression among Latinos with HIV and viral non-suppression. Participants will receive ADELANTE (5-session, community health worker-delivered, problem-solving intervention) or enhanced care condition (ECC, 5 reminder phone calls). We will evaluate the overall effectiveness of ADELANTE compared with ECC on rates of viral suppression and emergency room visits and hospitalizations. Our hypothesis is that ADELANTE participants will achieve higher rates of viral suppression and will have lower rates of emergency room visits and hospitalizations compared with ECC at 12 months post-randomization.
The goal of this trial is to understand which strategies work best to support pre-exposure prophylaxis (PrEP) use among female sex workers (FSW) and adolescent girls and youth women (AGYW) in uMgungundlovu, KwaZulu-Natal, South Africa. Participants will be randomly assigned to receive a combination of up to four support strategies encourage the participants in continuing to use PrEP. The four strategies being tested are: case management, food vouchers, peer support buddies, and community-based PrEP pick-up points. The intention of this trial is to determine which PrEP support strategy or bundle(s) of strategies best promote(s) long-term PrEP use, so that these services can be scaled up to other districts in South Africa.
This study aims to improve HIV healthcare services for mothers living with HIV and their newborns in Tanzania and Mozambique. The main questions it aims to answer are: 1) does enhancing screening with maternal HIV viral load monitoring at delivery identify more mother-child pairs at high-risk for HIV vertical transmission? and 2) are high-risk infants linked to appropriate prevention and care? The study will expand access to HIV testing services to more rural settings using a hub-and-spoke referral system.
The scientific premise of this research is that individual, interpersonal, and structural factors impact Black girls' sexual reproductive health outcomes (sexually transmitted infection (STI) and Human Immunodeficiency Virus (HIV)) and experience of sexual violence. This study expands STI/HIV prevention programs to include Black male caregivers, a potentially valuable yet underutilized resource to protect Black girls and reduce their exposure to STI/HIV and sexual violence.
The Human Immunodeficiency Virus (HIV) epidemic persists in France, with approximately 6000 new cases per year. Various prevention tools against HIV exist, including condoms, regular testing, Post-Exposure Prophylaxis (PEP), HIV treatment for seropositive partners, single-use disposable injection equipment for drug use and pre-exposure prophylaxis (PrEP). Continuous or on-demand PrEP with tenofovir disoproxil fumarate/emtricitabine has proven effective in reducing the risk of HIV infection. France was the first European country to authorize PrEP, leading to an unprecedented impact on seropositivity discovery rates in 2018, with a 7% decrease in new infections compared to 2017. However, the effectiveness of PrEP can be hindered by challenges in retaining users within the healthcare system. According to the EPIPHARE report, which has been monitoring Truvada® or generic PrEP use since 2017, a substantial proportion of new users do not receive PrEP renewal in the first 6 months after initiation. Such early interruptions, increasing in frequency, affected around a quarter of individuals who initiated PrEP in the second half of 2021. A recent study reported that these early interruptions have a significant detrimental impact on PrEP effectiveness in real life, especially among those under 30 years old and in socio-economic precarious situations. The main barriers to PrEP adherence are multifactorial, including social precarity, limited PrEP access, and a low perception of HIV risk. To address this, in France, general practitioners have been authorized to issue initial PrEP prescriptions since June 1, 2021. The future challenge is to increase PrEP use and optimize retention to combat the HIV epidemic, relying significantly on general medicine. The goal of our study is to broaden PrEP access by optimizing its initial prescription in general medicine and to assess user retention in PrEP care through the established partnership between general practitioners and patients. The research will be conducted in collaboration between Saint Louis Hospital in the 10th arrondissement of Paris and general practitioners willing to participate in the study, located in the 3rd, 10th, 11th, 13th, and 19th arrondissements. Participating general practitioners may be in private practice, employed in health centers, or working in health houses. As part of the study, general practitioners will receive training from the infectious diseases department of Saint-Louis and Lariboisière hospitals. This training will be both theoretical and practical, with the opportunity to attend initiation and follow-up PrEP consultations in the department. A dedicated phone line in the infectious diseases department of Saint Louis Hospital will be available for participating general practitioners seeking specialized advice. They will be encouraged to register as PrEP prescribers in their appointment scheduling software. Patients will be informed of the study objectives and its process by the general practitioner, and their oral non-opposition will be collected. Each inclusion consultation will last approximately 20-40 minutes, allowing the general practitioner to prescribe PrEP, conduct the usual care consultation, and collect clinical, demographic, socio-economic, lifestyle, medical history, and patient vaccination data on a dedicated data collection form. The follow-up duration will be two years, with consultation frequency matching that of regular PrEP follow-ups, and data collection will occur at M6, M12, M18, and M24 using a dedicated data collection form. Data collected during inclusion and follow-up consultations will be anonymized and integrated into the electronic Clinical Report Form. During each PrEP consultation (initiation and follow-up), general practitioners will provide patients with a PrEP prescription if the pre-PrEP biology report allows it (according to HAS (Haute Autorité de Santé) recommendations). For patients who have not been attending consultations, a telephone survey will be offered to inquire about PrEP continuation and collect information on follow-up or reasons for stopping PrEP.
Main objective is: - To characterize the evolution of the immuno-virological profile of circulating blood cells and immune aging in patients who had participated to TEMPO-1 in 2007-2008 - To evaluate the role of immune aging and inflammatory profile in the occurrence of comorbidities in HIV-infected individuals over a 15-year period The alterations that affect the innate and adaptive immune cell compartments in HIV-infected patients are reminiscent of the process of immune aging, characteristic of old age. These alterations, the presumed cause of which is the chronic systemic immune activation established in patients, contribute to the depletion of lymphoid resources which probably leads to the decline of immune competence with the progression of HIV disease. The comparison between HIV-1-infected patients and uninfected older adults goes beyond the mere appearance of immunosenescence and extends to the deterioration of a number of physiological functions linked to inflammation and to systemic aging. By inducing persistent and lasting immune activation, HIV-1 infection is now considered a model of accelerated immunosenescence and systemic aging. During this process, the immune system quickly becomes exhausted, because the source of its exhaustion (i.e. HIV) cannot be eliminated. To determine which factors may contribute to immunosenescence in HIV-1 infection, we propose an extensive immune and virological evaluation in patients who participated in a cross-sectional assessment of immune functions and TEMPO-1 viral reservoirs after 15 years of evolution in order to determine their immune and viral trajectories, to compare these trajectories with the major clinical events and the comorbidities occurring in them.
The clinical trial is a dose-escalation, randomized, double-blind, placebo-controlled phase I study at a single center to evaluate the safety, tolerability and immunogenicity of HIV Therapeutic DNA Vaccine, ICVAX, in clinically stable HIV patients under ART treatment.
The goal of this hybrid (1a) Cluster Randomised Controlled Trial phase 3B trial is to evaluate the effectiveness and implementation of offering a choice of HIV Pre-Exposure Products (PrEP) through community-based sexual and reproductive health services, on PrEP uptake and retention, and population prevalence of sexually transmissible HIV amongst adolescents and young adults living in rural South Africa. Researchers will compare adding the choice of long-acting PrEP, i.e. two monthly injectable cabotegravir (CAB LA) or dapiravine vaginal ring and HIV post exposure prophylaxis packs to daily oral PrEP integrated with community-based SRH in the 20 intervention clusters with standard of care (SoC), daily oral PrEP integrated with community-based SRH in the 20 control clusters, on uptake and retention on PrEP. We hypothesise that offering a choice of long-acting or oral PrEP and PEP within the community-based delivery of SRH services will overcome the challenges and barriers to effective use of oral daily PrEP and lead to a population-level effect on uptake and retention on PrEP and thus the prevalence of sexually transmissible HIV amongst 15-30 year olds living in rural KwaZulu-Natal, South Africa.
