African American and Latina women, as well as women living in poverty, are an identified health disparities population for HIV. Risks for HIV are compounded in this population when additional risk factors are present, including other sexually transmitted infections, intimate partner violence, substance use disorders, and homelessness or housing insecurity. Knowledge of one's HIV serostatus is key to linkage to care, improving HIV outcomes, and decreasing the spread of HIV. However, roughly a third of African American women and over half of Latina women have never been tested (CDC, 2016a). Barriers to testing include socioeconomical inequality, racial discrimination, low health literacy, and inadequate access to quality healthcare, among others. Novel methods for increasing HIV testing in this important health disparities group are greatly needed. This study aims to test a reinforcement-based intervention to increase HIV testing and repeat testing among African American, Latina, and women living in poverty who have risk factors for HIV. We are partnering with multiple community-based organizations, several of which are non-traditional providers of HIV services (e.g., domestic violence agency, homeless shelter), to address systemic and structural issues that serve as barriers to testing. A primary aim is to evaluate the effectiveness of training community-based providers to deliver a reinforcement-based intervention for promoting HIV testing. In addition, we will compare standard referral services for HIV testing plus HIV risk reduction education to the same plus reinforcement for HIV testing (and repeat testing) using a randomized controlled trial with 334 participants. Women in both groups will be encouraged to seek HIV testing; be provided with the resources to do so (list of testing sites, bus passes if needed); and will receive basic education about HIV prevention using a widely available web-based resource (https://wwwn.cdc.gov/hivrisk/). Women in the reinforcement group will also be provided with $25 for undergoing an HIV test, with a $15 bonus if they have the test in the next 7 days ($40 total). During the next 12 months, they can receive an additional $25 for undergoing up to 2 more tests separated by 12 weeks, with $15 bonuses for each test completed within 7 days (+/- 7 days) of the scheduled date at 6- and 12-months post-initial test. It is hypothesized that the reinforcement intervention will result in greater proportions of women receiving an HIV test (and repeat HIV tests) compared to standard services. In the proposed study, approximately 50 clinicians from our partner sites will be trained on both the non-reinforcement and reinforcement approaches to increasing HIV testing. Primary clinician outcomes are clinician knowledge and attitudes about HIV, testing, and reinforcement interventions. These will be assessed pre- and post-training and at 6-month intervals thereafter. A secondary outcome is clinician satisfaction with the training. Once clinicians are trained to competence, 334 women at our partner agencies will be randomized. Participants will be assessed at baseline and at 3-, 9-, and 15-month follow-ups. The primary outcome is objective reports of HIV testing, verified by testing centers. Secondary outcomes are HIV risk behaviors, test results, self-efficacy, client attitudes towards testing, and HIV knowledge. In addition, this study will include a careful analysis of costs of the reinforcement intervention to allow for estimates of its cost-effectiveness in increasing HIV testing. The overall goal of this study is to determine whether a reinforcement intervention delivered by community providers is superior to standard referral procedures plus HIV education in increasing rates of HIV testing among women at the highest risk of HIV infection. A wide range of community partners that serve some of the highest risk groups of women were chosen to ensure highly generalizable results. If efficacious, the intervention has the potential for widespread adoption and implementation.
The purpose of the study is to evaluate the safety, pharmacokinetics and pharmacodynamics of, and the tolerability and acceptance of an intravaginal ring (IVR) delivering both tenofovir and levonorgestrel (TFV/LNG) and an IVR delivering TFV only, compared to a placebo IVR, in women in Western Kenya.
The primary objective of this study is to determine if an HIV-infected donor liver (HIVD+) transplant is safe with regards to major transplant-related and HIV-related complications
Background: There are many people living with human immunodeficiency virus (HIV) infection in Liberia. Most experts consider HIV an epidemic there. Researchers want to collect health data from Liberians with HIV over several years. This may help HIV prevention and treatment programs in Liberia. Objective: To learn more about how HIV affects people in Liberia. Eligibility: People with HIV in Liberia Design: Participants will be screened with a blood sample. Participants will visit the study clinic about 10 times over 3 years. They will need to return to the clinic after some visits to get test results. The visits will be closer together during the first part of the study and less frequent later. At each study visit, participants will: - Have a brief physical exam - Answer questions about how they are feeling and what medicines they are taking - Have blood taken from an arm vein by a needle - Give urine samples Participants ages 12 years or older may be asked questions about HIV risk behaviors. These include sex practices and drug use. Participants ages 18 years or older may be asked how their HIV infection makes them feel emotionally. Participants may be asked to join a research substudy. This will be about tuberculosis (TB) testing in people with HIV. For this substudy, participants will have a TB skin test. A small amount of liquid will be injected under the skin on the arm. Participants will return to the clinic a few days later. The test area will be checked. They will get their test results.
Emerging data suggest that HIV-infected people have disproportionately higher risk of diabetes than HIV-uninfected people. Multiple factors may contribute to elevated diabetes risk including increased prevalence of conventional non-communicable diseases (NCDs) risk factors, use of some antiretroviral drugs regimens, and inflammation and immune activation secondary to environmental- and HIV-enteropathy. To date, enteropathy has been little studied in relation to HIV and diabetes in Sub-Saharan Africa. Enteropathy leads to systemic inflammation which may in turn result in insulin resistance and may reduce secretion of incretins, the gut hormones which stimulate synthesis and secretion of insulin. Both mechanisms could potentially result in higher diabetes risk in HIV patients. This study investigates the hypothesis that among HIV-infected patients environmental enteropathy increase the risk of diabetes. The findings of this study will provide information which could be used as a basis for developing clinical trials to address different aspects of environmental enteropathy in order to reduce the burden of diabetes among HIV-infected populations
Cardiovascular disease is a major cause of morbidity and mortality among people living with HIV. Recent studies have demonstrated that patients with HIV experience a 50-100% increased risk of myocardial infarction and stroke compared to HIV-uninfected persons. They also face higher risks of stroke, sudden death, and heart failure. However, evidence-based statin therapy-which is safe in this population and highly effective at reducing cardiovascular risk-is under-prescribed. The investigators propose a multi-level intervention to increase evidence-based statin prescribing by addressing barriers at these levels. The implementation intervention includes two strategies: (1) tailored education at the leadership, provider, and patient levels, and (2) behavioral economics-informed feedback for providers.
Hepatitis B virus (HBV) infection can be treated, but therapy is usually lifelong and has side effects, so a cure for HBV is a critical endpoint. This study examines the key steps to HBV cure in the setting of HIV-HBV co-infection, where rates of development of antibodies against HBV after starting HBV treatment are higher than in people with HBV alone starting treatment. In Asia both HBV and HIV are common so this provides a unique opportunity to study HBV. We will investigate how an effective immune response against the two main HBV proteins is developed. If we can understand how the immune response works against HBV, this could be used to develop new therapies towards a cure for HBV
This research study is being carried out to study a new way to possibly treat HIV. As part of this study, doctors will take some of your own white blood cells, called T-cells, and modify them so that they can identify and target your HIV cells. The purpose of the study is to evaluate the safety of these modified T cells and determine whether they have any effect on HIV infection.
This study will evaluate the safety, tolerability and innate immune mechanisms activation following administration of the combination of Pegylated Interferon alpha 2b (peg-IFN-α2b) with two broadly neutralizing antibodies (3BNC117 and 10-1074) in the setting of well-controlled HIV infection with antiretroviral treatment and a monitored analytical treatment interruption. The current proposal builds on previous experience using interferon alpha, 3BNC117 and 10-1074 alone in separate clinical trials that included a closely monitored analytical treatment interruption. The hypothesis is that the joint administration of peg-IFN-α2b with 3BNC117 and 10-1074 will be more effective than either intervention separately in suppressing HIV viremia during 8 weeks of analytical treatment interruption (Step 4) and reducing integrated HIV DNA in blood and tissue when measured during an analytical treatment interruption in patients with well-controlled HIV infection.
