Filter by:What is known: There are 1.2 million people in the US who meet the indications for PrEP; yet, disparities exist in uptake. For example, only 9% of Black and 16% of Latino individuals, compared to 65% of White individuals, have been prescribed PrEP. At Henry Ford Health (HFH) system, only 10% of eligible patients have been prescribed PrEP. Primary care is an ideal setting for PrEP to be offered as an HIV prevention method since providers see large numbers of patients who are HIV negative, with some who are at increased risk for HIV, and the primary care setting is often the point of entry to the healthcare system. The multiphase optimization strategy (MOST) framework is a novel, innovative way to identify an efficient intervention. What will be done: In this optimization trial, the investigators will test the effectiveness of intervention components, alone and in combination, on new PrEP prescriptions in primary care at HFH. First, feedback will be generated on context-specific (system and individual level) factors for intervention component delivery via focus groups with providers (n=15) and patients eligible for PrEP (n=30). Then, four intervention components will be tested in an optimization trial, with 16 conditions being implemented at 32 clinics. Finally, feedback will be generated on the factors that affected implementation via semi-structured interviews with providers (n=30) and patients (n=30). Participants will be primary care providers (PCPs) and patients eligible for PrEP in Henry Ford Health System. Clinics will be randomized (yes/no) to receive any combination of provider and patient intervention components. Provider intervention components include computer-based simulation training and/or best practice alerts delivered via the electronic health record (EHR). Patient intervention components include HIV risk assessment and/or PrEP informational video - both delivered via the EHR. Primary outcome is the rate of new PrEP prescriptions at the clinic level. Secondary outcomes will include PrEP maintenance, number of HIV tests ordered by a PCP, and number of PCPs trained. Sub analyses will test which factors moderate (e.g., patient sex, race, age, gender, sexual orientation) or mediate (e.g., perceived HIV risk, provider and patient PrEP knowledge) PrEP uptake, focusing on priority populations and disparities in rates of PrEP prescription. Implications: 1) Understanding which intervention components lead to increased PrEP prescriptions will represent an important advance in HIV prevention efforts. 2) Optimizing a multi-level intervention for providers and patients to increase PrEP prescriptions would lead to a new, efficient, evidence-based option. 3) Determining what factors are related to PrEP uptake will help reduce disparities in PrEP initiation among those most in need. 4) Understanding the context specific factors related to intervention component implementation will help identify best methods for replication/adaptation in other healthcare systems.
To evaluate the anti-interference and specificity of HIV Ag +Ab Assay Kit (Sysmex) for the detection of HIV antigens and antibodies.
This is a dual arm (arm 1 and arm 2) multi-centric non-randomized (prospective) study. Two new multicentric cohorts will be set up in 4 Belgian HIV reference centers (UZ Gent, UZ Brussel, University Hospital Liege and St. Pierre Hospital Brussels): cohort 1 will comprise PLWH in whom ART was initiated during acute HIV infection minimum 3 years ago but no more than 10 years ago (short-term ART cohort); cohort 2 will comprise PLWH on ART since >20 years (long-term ART cohort). Participants will be included based on suppressed viremia and uninterrupted ART since initiation. Participants will undergo one blood sampling and one leukapheresis. In and exclusion criteria are described below.
The main objective of this study is to evaluate the interest of a screening strategy based on the HPV test in patients living with HIV, compared to the cell smear alone in the same population. The Secondary objective of this study is to verify if the use of HPV testing could allow for a longer follow-up of these patients in case of negativity, and thus allow for a standardization of clinicians' practices.
The primary aim of this study is to learn whether the frequency of lower urinary tract symptoms differ between the males with seronegativity for HIV and males living with HIV.
The research team has developed an interventional group program for young men living with HIV and will be adapting it for telehealth delivery. The purpose of the study is to determine whether or not this program can help improve social connections and the health of young men in online delivery and evaluate its potential for implementation in a community setting. The study has three phases: (1) engaging a community advisory board to create and adapt the intervention for online delivery, (2) a randomized clinical trial of the online intervention, and (3) evaluation of the program for community implementation with our partner organization. Participants in the second phase of the study will meet with a study team member to discuss the research process and provide informed consent. The community organization employees will provide consent online prior to completion of a survey and indicate whether they consent to be contacted further for in-depth interviews.
The goal of this Hybrid Type I effectiveness-implementation trial is to test Project nGage, an evidence-based, flexible, and tailored intervention that leverages existing social network members to promote retention in care and viral suppression among young Black sexual minority men (YBSMM) aged 18-35.
A small pilot study to assess feasibility and acceptability of the PL4Y intervention.
PrEP (pre-exposure prophylaxis) is an effective prevention strategy in which HIV-negative individuals take antiretroviral drugs (tenofovir disoproxil fumarate and emtricitabine - TDF/FTC) to reduce HIV acquisition. Clinical studies have shown that the TDF/FTC combination protects MSM and transgender women against HIV infection. According to the PROUD study, PrEP can decrease the risk of HIV infection among MSM by 86% (90% CI 64-96). The international community recognizes that PrEP can be an additional tool in the framework of a combination prevention package for those most at risk of contracting HIV. Data on HIV incidence among MSM and trans women are largely unknown. In Brazil, Mexico and Peru, data on the incidence of HIV among MSM and trans women are very scarce, limited to small cross-sectional studies.Current methods used to determine HIV-1 incidence have many limitations. These methods include mathematical modeling, retrospective calculations of AIDS case reports, age-based prevalence determinations, and prevalence determinations with multiple rounds of longitudinal surveys to estimate HIV incidence, which require numerous assumptions and inputs and can pose additional challenges in the era of expansion of antiretroviral therapy (ART) and increased survival of HIV-1 infected individuals. On the other hand, prospective longitudinal cohort studies of high-risk individuals can be used to estimate incidence; however, they are often labor-intensive, complex, very expensive, difficult to implement in most countries, and have recruitment biases. Laboratory methods can be unbiased and do not require complicated assumptions and case-by-case weighting. The cross-sectional use of Recent HIV Infection Tests (TRIs) based on biomarkers offers, in principle, accessible, reliable and low risk of bias options for estimating incidence.
The aim of this study is to identify both the humoral immunological response through the detection of induced antibodies and the cellular immunological response through the detection of interferon gamma production by functional CD4+ and CD8+ cells in different groups of immunocompromised patients. For antibody detection, LIAISON® SARS-CoV-2 TrimericS assay (DiaSorin) will be used and for the evaluation of cellular immunity - QuantiFERON SARS-CoV-2 assay (QIAGEN).
