Filter by:In this study, investigators plan to evaluate the cardiometabolic effects of initiating gender-affirming hormone therapy among transgender women with and without HIV. As part of this study, participants will undergo cardiovascular and metabolic phenotyping within 3 months of starting and after 12 months of gender-affirming hormone therapy. Cardiovascular phenotyping will include cardiac MRI/MRS imaging to evaluate cardiac function and structure. Metabolic phenotyping will include oral glucose tolerance testing, abdominal MR imaging to evaluate visceral adiposity, and whole body, lumbar, and hip DEXA imaging to evaluate fat and lean body mass as well as bone mineral density, respectively. Traditional markers of CVD risk as well as immune, hormonal, and coagulation parameters will also be assessed longitudinally.
The standard treatment for TB consists of rifampicin (RIF) as part of the regimen. However, due to drug-drug interactions (DDI), the bioavailability of PIs is greatly reduced when co-administered with RIF necessitating use of higher doses of the PI to overcome this effect. However, the potential effect of this increased dose on the DDI with bPIs is uncertain. Though some data has been collected that shows safe use of higher doses of LPV to overcome the DDI with standard doses of RIF in HIV-infected individuals, no substantive data has been collected on ATV to correctly adjust its dose when co-administered with RIF-based TB treatment. Physiologically-based pharmacokinetic (PBPK) modelling was developed to understand ATV and RIF DDIs, and identified potential dosing strategies to overcome this challenge in adults and special populations under workpackage 1 of the VirTUAL consortium. From this work, it is anticipated that the dose of ATV/r should be increased from 300/100 once daily to 300/100mg twice daily in order to overcome the interaction with rifampicin and attain therapeutic plasma concentrations. This dose escalation trial aims to: 1. Evaluate the steady state plasma and intracellular PK of ATV/r, when administered in adjusted (PBPK model-predicted) doses concurrently with RIF 2. Evaluate the safety and tolerability / acceptability of the adjusted dose of ATV/r that provides the therapeutic concentration when co-administered with RIF. 3. Evaluate the concentration of dolutegravir (DTG) and RIF when co-administered and explore the potential DDI with ATV/r
This cluster randomized control trial examines whether an audit and feedback study improves care of patients living with HIV/AIDS in a family health team setting.
Three induction treatment strategies [ voriconazole +5FC vs. amphotericin deoxycholate (0.4-0.5 mg/kg/d)+5FC vs. amphotericin deoxycholate (0.7-1.0 mg/kg/d)+5FC ] for HIV-infected patients with cryptococcal meningitis were compared.
This study is being done to evaluate the relationship between adherence to antiretroviral therapy (ART) and HIV drug concentrations in persons living with HIV (PLWH) that are taking tenofovir alafenamide (TAF). Adherence will be measured with an ingestible biosensor (digital pill). Antiretroviral drug concentrations will be measured in different types of blood cells.
Our proposed study will: provide a novel exploration of facilitators and barriers to PrEP; allow us to target hard to reach populations, including men who have sex with men (MSM) and substance users (both of which are top funding priority groups for the National Institutes of Health) who experience intersecting markers of HIV risk; and inform regional, and possibly national, intervention approaches to combat the overlapping epidemic of HIV and incarceration.
This is a randomized clinical trial of doxycycline post-exposure prophylaxis (dPEP) to reduce bacterial STIs among Kenyan women taking pre-exposure prophylaxis (PrEP). The overarching goal is to assess the effectiveness of dPEP on incidence of STIs while also balancing acceptability, cost, and impact on tetracycline resistance to inform public health policy. Participants will be randomized to receive dPEP and standard of care or the standard of care only. Questionnaires, focus group discussions, SMS, and in-depth interviews will be used to study acceptability and changes sexual behavior due to dPEP.
This is a randomized, double-blinded, placebo-controlled trial designed to assess the effect of the GLP-1 receptor agonist, semaglutide, on visceral and ectopic fat, insulin resistance, inflammation markers, and the downstream effect of cardiovascular risk in people with HIV. The primary endpoints will be visceral and ectopic fat changes over the study period. The secondary endpoints will include changes in markers of inflammation, immune activation, gut integrity, and cardiovascular disease risk assessment.
The Options for Delivering Isoniazid-Rifapentine (3HP) for TB Prevention (3HP Options Implementation Trial) study will be a three-arm, open-label, parallel, randomized trial. This hybrid effectiveness-implementation trial will be conducted among people living with HIV infection (PLHIV) enrolled in HIV/AIDS care at the Mulago Immune Suppression Syndrome (i.e., HIV/AIDS) clinic in Kampala, Uganda. The overall objective of this study is to identify a patient-centered delivery strategy that will facilitate acceptance and completion of a three-month (12-dose) regimen of weekly rifapentine (RPT) and isoniazid (INH) by PLHIV enrolled in routine HIV/AIDS care in a high HIV/TB burden country. The primary outcome will be acceptance and completion of 3HP. Additional objectives will be to evaluate the implementation and cost-effectiveness of each delivery strategy.
This trial will evaluate whether empirical treatment against cytomegalovirus and tuberculosis improves survival of HIV-infected infants with severe pneumonia.
