Filter by:In this study, the investigators propose to develop Improving AIDS Care after Trauma (ImpACT), an intervention based on theories of stress and coping and evidence-based treatment for traumatic stress. The intervention will target women in South Africa who have histories of sexual trauma and are newly initiating antiretroviral therapy (ART) in order to reduce avoidant coping and traumatic stress, improve care engagement, and reduce HIV risk behaviors.
The purpose of this research study is to test a group program aimed at improving the quality of life of HIV+ Black men who have sex with men. The group will address ways to cope with discrimination and will help men examine mistrust that they may have about healthcare, including doctors and other healthcare providers and HIV medications. The aim is to provide a supportive community for HIV+ Black men.
The purpose of the study is to look at the levels of three HIV medications: dolutegravir, elvitegravir and cobicistat in blood after the drug intake has been stopped in order to understand how long these drugs persist in the blood. The study will specifically look at blood levels of these three drugs after taking them every day for 10 days dolutegravir on a first stage and a combination of elitegravir and cobicistat in a second stage. If the participant decides to take part, the duration of the study will be up to 38 days plus a screening visit which will take place up to 28 days prior to the start of the study, and a follow up visit which takes place 7 to 14 days after the last dose of study medication. This study is not randomised which means that all participants will receive all study medications in the same order. The participant and the study doctor will know which study medications the participant is taking at all times during the study.
The proposed study will test the efficacy of a cognitive training program to improve working memory in a sample of HIV-infected persons. Investigators will assign 40 HIV-infected adults with poor medication adherence to one of two conditions (20/group): the experimental cognitive training intervention or a control training condition. Participants will complete 12 training sessions across 10 weeks and will complete assessments at baseline and post-training. The specific aims are to: 1. Investigate the effects of the cognitive training intervention on working memory and delay discounting in HIV-infected persons. Hypothesis 1: Participants assigned to active cognitive training, compared to those in the attention-matched control group, will have greater improvements in working memory and reductions in delay discounting. 2. Characterize adherence to antiretroviral medications in this population and examine medication adherence after cognitive training. Hypothesis 2: Participants assigned to active cognitive training, compared to those in the attention-matched control group, will have greater improvements in medication adherence.
People infected with HIV are living longer thanks to the use of antiretroviral therapy (cART). In aging HIV persons, other factors are associated with early death. One of the major factors is liver disease, which can be due to liver infections or reasons such as fatty liver. Fatty liver in the general population is a serious problem, affecting 30% of Canadian population. A specific type of fatty liver characterized by much inflammation, named nonalcoholic steatohepatitis (NASH) can lead to cirrhosis and death. Persons living with HIV can be at increased risk of NASH because of toxic effect of certain types of cART on the liver, obesity and other metabolic factors (for example diabetes). Some scientific data suggest that newer cART are associated with less fatty liver and liver damage. However, NASH has not been studied in detail in persons living with HIV. One reason for the lack of research is one of the only ways to detect liver disease is to undergo liver biopsy which can be painful and has complications. Recently, a new non-invasive technology (Fibroscan) has been developed which can tell doctors how much a liver is damaged and how much fat it contains without pain or complications. Moreover, a simple test measuring a specific protein in the blood, the cytokeratin 18 (CK-18), can help the diagnosis of NASH. We will study the effect of switching cART to newer types of HIV medication in patients with a non-invasive diagnosis of NASH done by Fibroscan and cytokeratin 18. We expect that switching older cART to less hepatotoxic drugs will lead to improvement of liver damage, fatty liver and NASH diagnosed by Fibroscan and cytokeratin 18. To evaluate this approach we plan to recruit 58 consenting HIV mono infected patients with non-invasive diagnosis of NASH and/or fatty liver with liver damage. Participants will undergo Fibroscan, a blood test for cytokeratin 18, a complete physical examination and laboratory tests every 3 months for 12 months, then at 18 and 24 months. The effect of the switching of HIV medications will be recorded. We anticipate that the current study will provide evidence for reduction of inflammation and liver damage with newer cART for treatment of HIV infection.
This is a phase 1, single-site study is to evaluate the safety and immunologic and virologic efficacy of ex vivo expanded HIV-1 multi-antigen specific T-cell (HXTC) therapy in HIV-infected individuals with viral suppression on antiretroviral therapy (ART).
Medication adherence is one of the most salient predictors of patient outcomes in the era following development of effective treatment for HIV infection. Evolving strategies to improve adherence, specifically incentive interventions and real-time medication monitoring, have shown some success in limited studies. Further investigation into incentive interventions for HIV-infected adolescents with poor medication adherence is necessary.
Significant increases in HIV diagnoses among gay and other homosexually active men, in Australia and internationally, have been observed since the late 1990s. The levels of high HIV risk sexual practices among gay men have also increased, particularly unprotected anal intercourse (UAI). Nationally, over three quarters of the new HIV infections diagnosed annually are among men who have sex with men (MSM). The proportion of heterosexual men and women among those diagnosed with HIV annually has also increased in recent years. Despite successes in some situations, HIV transmission has not been adequately reduced by the prevention methods available to those at risk, such as education, condoms, and treatment of sexually transmitted infections (STIs). The effectiveness of daily oral antiretroviral medications (ARVs) as preexposure prophylaxis of HIV (PrEP) has now been established by clinical trials in both heterosexual adults and homosexual men. Whether PrEP confers high rates of protection in real life situations and is a feasible strategy to implement still requires further investigation. Through its "HIV prevention strategy 2015: New era," NSW Health committed to consider how to most appropriately and efficiently implement PrEP in line with evidence. This commitment translated in the support to this PrEP demonstration project. This demonstration project is designed to evaluate the off-label provision of daily combination of tenofovir disoproxil fumarate and emtricitabine (TDF/FTC, known as TRUVADA) as PrEP to a sample of sero-negative individuals at high risk for HIV infection in clinical settings in New South Wales. The project will inform policy development regarding primary HIV prevention with PrEP. This is an open-label, single-arm treatment evaluation study. All consenting and eligible HIV negative participants will receive TRUVADA prescribed for daily administration orally. At each followup visit, the following procedures will be conducted: clinical evaluations/ procedures, laboratory evaluations/ procedures, testing for HIV, STIs, hepatic and renal function, assessment for adherence to the prescribed medication, side effects, eligibility for next TRUVADA prescription, and willingness to continue on PrEP. As a study requirement, participants will be offered a self-administered assessment of behaviour, lifestyle and attitudes which will be conducted ideally within two and no more than seven days of the clinic visit in the participant's private space. Analyses will include: the feasibility of PrEP delivery, adherence to the study medication, safety and tolerability, the effects of PrEP use on behavior, and statistical analyses of the risk of HIV seroconversion.
The main objective of this study is to compare the tolerability and adherence to a new drug regimen of post-exposure prophylaxis (PEP) for HIV,
The purpose of this study is to evaluate the impact of a community mobilization intervention on the uptake of HIV testing, linkage to and retention in HIV care using a community, cluster randomized trial.
