Active clinical trials for "HIV Infections"

This protocol describes a 2-arm cluster, randomized controlled trial designed to test the effectiveness of a conditional cash transfer on viral suppression at 6 months among people living with HIV infection (PLHIV) in Tanzania who have disengaged from HIV care. Randomization will take place at the clinic level (HIV primary care clinics). The comparison group receives standard of care standard of care HIV tracing services according to Tanzania's National Guidelines for the Management of HIV and the Ministry of Health to locate potential participants, including home based care (HBC) tracing of PLHIV who have disengaged from primary care, the provision of counseling to return to HIV care, and the offer to schedule an HIV primary care appointment on the spot. Eligible adult PLHIV disengaged from HIV care and living in an intervention facility catchment area will receive the same standard of care HIV tracing and clinical services as control participants, plus the opportunity to receive a one-time cash transfer incentive, conditional upon confirmed completion of a clinical visit if within 90 days of study enrollment. The primary endpoint is viral suppression (<1000 copies/ml) at 6 months after study enrollment.

The purpose of this study is to examine the feasibility, acceptability and effect of a combined smoking cessation intervention integrating contingency management (reward-based) strategies with Mindfulness training to identify the optimal dynamic strategy to promote smoking cessation among HIV patients.

In this study, the investigators hypothesize that THC alters the immunogenome in a cell type-specific fashion and alters cytokine production via epigenetic regulatory mechanisms and that these alterations differ between HIV-infected and HIV-uninfected host genomes.

This study aims to test a new approach to support people living with Human Immunodeficiency Virus (HIV) in Uganda. Traditional healers (TH) will be trained to provide counselling and testing for HIV, help patients start antiretroviral therapy quickly, and offer guidance on taking medications and staying in HIV care. This support will be given in addition to the regular care provided at clinics. The main goal of the study is to see if this new approach can help more people in rural areas achieve viral suppression.

B-HAPPY is an implementation project to study the process by which pre-exposure prophylaxis (PrEP) is introduced and integrated into a specific international health system facing high rates of HIV incidence among men who have sex with men. The study will use a stepped wedge design to compare implementation outcomes across eight municipalities in Yunnan, China.

Most Veterans living with HIV are 50 years of age or older and can expect to live more than 20 years longer with HIV medication. However, despite this success, Veterans living with HIV are more likely to have age-related diseases and loss of fitness and muscle that place them at increased risk for disability. This is a major priority for the VHA, the largest provider of HIV care in the United States. The goal of this study is to test a circuit exercise program in Veterans living with HIV that is designed to slowdown the aging process. The exercise program will be widely available by Video Teleconferencing (VTEL) and does not require stationary exercise equipment, making it widely accessible. This research will help reach the goal for Veterans to preserve their quality of life and ability to function independently. Novel findings will strengthen strategies to maintain life-long fitness through a personalized exercise prescription.

To achieve the end of the HIV epidemic, concerted efforts will be needed to address the HIV care continuum, including improving retention in care (RIC) and viral suppression (VS) among persons with HIV (PWH). In the U.S., less than 50% of PWH are RIC and even fewer are VS. Studies have shown that these PWH have poorer clinical outcomes and are at risk of transmitting HIV to others, hence the need for innovative solutions to improve retention in care and subsequent viral suppression. Theory-based mHealth interventions have been shown to be promising in reaching these at-risk groups and improving HIV-related outcomes. PositiveLinks is a clinic-deployed mHealth platform that includes patient and provider smartphone apps, a web portal for clinic staff and providers to manage patient cohorts, an online implementation guide, and a learning management system to train and certify clinic staff. It has theory-based features including daily queries of adherence, mood, and stress, graphical feedback for self-monitoring, secure messaging with staff, appointment reminders, anonymized peer support, information resources, and document upload capability to support insurance re-enrollment. A 12-month prospective study in poorly retained PWH found that PL increased RIC and VS, with app use related to benefit as well as improved social support and stigma. PL is a promising existing mHealth tool for PWH, yet its efficacy has not been tested in a randomized trial, nor in urban populations. The investigators will test the efficacy of PositiveLinks to improve RIC and VS among a cohort of PWH in a high HIV prevalence city of Washington, DC. Participants will be identified from the DC Cohort, a longitudinal prospective cohort of PWH receiving HIV care at 15 clinics in DC. First, the investigators will conduct formative research to assess the feasibility, acceptability and usability of PositiveLinks among this urban cohort and conduct subsequent adaptations based on these findings. The investigators will then conduct an efficacy study through a cluster randomized controlled trial at 12 DC Cohort sites among 482 PWH. Clinics will be randomized to PL or usual care. Primary outcomes will include VS, RIC, and visit constancy at 12 months. Finally, the investigators will conduct mixed methods implementation science research guided by the Consolidated Framework for Implementation Research and RE-AIM to identify site, patient, provider, and system factors that characterize best practices in program implementation. If successful, this research will lead to the development of a novel and efficacious approach to improving RIC and VS among PWH which could lead to dissemination research that will contribute to HIV epidemic control. This project is responsive to NIH priorities, National HIV/AIDS Strategy, and Ending the HIV Epidemic goals as it is cross-cutting, seeks to reduce health inequities, and to improve health outcomes to achieve sustained viral suppression in a geographic hotspot for HIV.

The PEERNaija application will feature routine medication reminders, along with individual adherence monitoring with adherence scores, anonymized peer adherence scores (from peers attending the same clinic; social incentive), and a monthly lottery-based prize for youth with the highest adherence scores (financial incentive). The Investigators will recruit a cohort of 50 HIV-infected adolescents and young adults (AYA) to pilot the app and assess feasibility, acceptability, adoption, and preliminary efficacy of important clinical measures (including adherence and virologic suppression). The proposed study will provide important preliminary data for the role of mobile health (mHealth) platforms to harness and deliver social and financial incentives to promote adherence efforts, especially for vulnerable youth, and for a larger intervention trial evaluating this app among HIV-infected AYA in Nigeria.

More than 90% of HIV-infected patients on antiretroviral therapy have an undetectable viral load. However, approximately 15% of these individuals do not sufficiently restore their TCD4 lymphocytes and have an unfavorable CD4/CD8 ratio despite good adherence and an undetectable viral load. Factors associated with immunovirological discordance include low CD4 cell counts prior to antiretroviral therapy, low CD4/CD8 ratios and positive cytomegalovirus (CMV) serology. These patients are at risk of significant non-AIDS events and mortality. The anti-sense protein (ASP) is synthesized from the anti-sense strand of HIV-1. A cytotoxic anti-ASP response of CD8 T lymphocytes and anti-ASP antibodies have been demonstrated in infected patients. The conservation of the ASP gene in HIV-1, the virus responsible for the pandemic, suggests that its maintenance confers an advantage to the virus. ASP induces an inflammatory phenotype in surrounding cells. ASP can be externalized by the cell through its interaction with its cellular partner Bat-3. Once externalized in soluble or exosomal form, Bat-3 has the ability to regulate NK cell activity. During HIV infection, NK functions are disrupted, including those related to the expression of the Bat-3 receptor, NKp30. In patients, the inflammatory phenomenon is strongly associated with chronic HIV-1 infection. The efficacy of antiviral treatments does not allow a complete normalization of either the immune system function or the inflammatory status of the patient. The observed effect of ASP on inflammation raises the question of the involvement of ASP in the maintenance of a chronic inflammatory state in patients under treatment. Increased inflammation has also been associated in HIV-infected patients with elevated plasma exosome levels. In patients undergoing treatment, chronic inflammation remains a major problem and an important source of comorbidities (cardiovascular in particular) and probably contributes to the immunovirological non-response in immunodiscordant HIV-infected patients. It is hypothesized that ASP bound to its cellular partner Bat-3 in exosomes would disrupt the cytotoxic activity of NK cells, sustain inflammation and have a deleterious effect on immune reconstitution.

Thailand remains one of the countries with the largest population of people living with HIV (PLWH). It is estimated that 30 Thai provinces account for 75% of the HIV infections in that country, with ChiangMai as the most prevalent province in northern Thailand. Also, HIV/AIDS remains among the top 10 most common causes of death in Thailand. This high mortality rate may be partially explained by the notable HIV treatment cascade in Thailand: Among all the Thai PLWH, only 74% were retained in care, while 68% received ART, and roughly 50% reached viral suppression. An important reason for this is that HIV-related stigma still poses significant barriers for Thai PLWH to access healthcare and carry out health-protective behaviors, including adherence to medication schedules, to manage their HIV. In Thailand, substance use, including use of tobacco, alcohol, and other emerging recreational drugs, is a pressing health concern. In the HIV+ population in Thailand, it was found that 15% use tobacco, 70% use alcohol, and 2% use recreational drugs. In addition, among Thai HIV+ alcohol drinkers, about 13%-22% were heavy drinkers and 40% had sex under the influence of alcohol. Although the literature evaluating prevalence of substance use among Thai HIV+ individuals is emerging, the knowledge remains very limited regarding their risk and protective factors for substance use. Self-management interventions, typically include training modules for symptom management skills and coping strategies. In Buddhist-Thai culture, the goal of self-management may become assisting PLWH to find the peace and harmony within themselves by gradually "letting go" of those strong desires for certain materials or status that contribute to the uncertainty in lives. Therefore, this project aims to further the investigator's knowledge about self-management behaviors in HIV+ substance users in the context of Buddhist-Thai culture. The investigator aims to: 1. Explore how PLWH experience and interpret substance use, mental health, and self-management and identify key social-cultural factors that influence these factors. 2. Test the associations among mental health, substance use, self-management, health outcomes and selected key social-cultural factors among PLWH using a partial correlation network model. The results will be used for development of a culturally tailored, evidence-based self-management intervention to promote better health outcomes among Thai PLWH.
