Filter by: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.
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 study is to test the maximum tolerated dose of ACU-D1 in HIV-positive people with HPV-associated vulvar and perianal lesions. The main questions it aims to answer are: - The maximum tolerated dose of ACU-D1 - Safety and tolerability of topical ACU-D1 - Whether topical ACU-D1 induces p53 and p53-mediated downstream signaling (including p21 induction) in HPV-related lesions - Whether topical ACU-D1 enhances markers of immunity in HPV-infected HIV-positive individuals Participants will be asked - To apply ACU-D1 on the lesions twice daily for 4 weeks - 3 biopsies will be performed at the screening and 3 at the end of 4 weeks.
The study will evaluate 300 people living with HIV that attend the Vivent Clinic for HIV care. We will characterize our population and include age, race/ethnicity, sex at birth, tobacco use, alcohol use, other comorbidities, HPV vaccination status, other HPV disease, and lab values such as CD4 count and HIV viral load. We will compare results between participants who are HPV positive and negative. We will also evaluate the relationship between HPV oral infections and lesions and the variables above to better understand possible predictors of HPV infections and lesions.
This is a Phase I, randomized, double-blind, placebo-controlled clinical study to define the safety and immunogenicity resulting from a rapid dose-escalating vaccination schedule as compared to that of a co-administered, dose-consistent vaccination schedule. Participants randomized to receive vaccines will get either dose-consistent injections of CH505 TF chTrimer+ALFQ co-administered with Ad26.Mos4.HIV or rapid, dose-escalating injections of CH505 TF chTrimer+ALFQ with an Ad26.Mos4.HIV prime, followed by dose-consistent injection of CH505 TF chTrimer+ALFQ co-administered with Ad26.Mos4.HIV
The overall goal is to determine whether an end-to-end decentralized delivery service for PrEP is more effective, safe, acceptable, and cost-effective than facility-based PrEP delivery.
Alcohol use disorder (AUD) has been associated with high prevalence of inflammation-associated co-morbidities in people living with HIV even those receiving effective antiretroviral therapy (ART). Our preliminary data support a model in which the combined insult of AUD and HIV on the gut, specifically on the microbiota and intestinal barrier integrity, exacerbates inflammation. Our preliminary data using intestinal organoids also suggest a potential mechanism for AUD-mediated changes in the gut barrier function during HIV; the intestines of HIV+ individuals have low resilience to alcohol induced intestinal barrier disruption caused by high levels of oxidative stress. Finally, our preliminary data also suggest a potential approach to enhance the integrity of the intestinal barrier and reduce gut derived inflammation in people living with HIV with/without AUD- short chain fatty acid prebiotics. These prebiotics prevent alcohol mediated adverse effects on the intestinal barrier and inflammation by preventing oxidative stress. These prebiotics are safe and decrease gut inflammation in humans. 20 HIV+ ART+ (10 AUD- and 10 AUD +), will be recruited for a prebiotic intervention. This is a proof-of-concept observational study to establish a causal link between microbiota-gut and HIV pathology during ART by asking whether modifying microbiota and gut milieu impacts intestinal barrier function, systemic inflammation, and brain pathology in HIV+ people. Participants will have two study visits, where stool collection and blood draw will be collected, as well as questionnaires. These participants are part of the larger observation study (n=160), which will test the hypothesis that intestines from HIV+ individuals have lower resilience to alcohol mediated gut barrier disruption than intestines from HIV-negative controls. We will recruit the following groups of participants: HIV+ ART+ AUD-; HIV+ ART+ AUD+; HIV- AUD- ; HIV- AUD+. Blood, urine, stool, and intestinal biopsies will be collected from participants to compare intestinal barrier integrity, system and gut inflammation, immune activation, oxidative stress, microbiome/metabolome. and HIV reservois. Second, lleal/colonic organoids from HIV- and HIV ART+ individuals will be generated to examine their resilience to alcohol-induced intestinal barrier disruption.
There is an urgent need to address HIV inequities and disparities in the US, particularly within vulnerable communities such as Hispanic/Latino gay, bisexual, and other men who have sex with men (HLMSM).
Building a Microbiome Data Platform and Conducting Clinical Evidence Research in Individuals Infected with the Human Immunodeficiency Virus (HIV) and Hepatitis B virus.
This study seeks to improve mental health, pregnancy, and HIV outcomes among pregnant and postpartum women living with HIV with common mental health disorders in Kenya. The investigators will tailor a collaborative care model for peripartum women with HIV experiencing mental health symptoms and evaluate its impact on participants' mental health, antenatal, and HIV care outcomes. The investigators will actively engage key stakeholders throughout the process and assess scalability and sustainability through multi-method approaches. This study will contribute to the overall goal of achieving optimal health outcomes for women living with HIV and their families in sub-Saharan Africa.
