Filter by:Various facts support the study of COVID-19 vaccine immunogenicity in People Living With HIV (PLWH) at this time: (1) Many PLWH in Canada will be eligible to receive COVID-19 vaccination as they are in a high priority risk group, such as residents or staff of shared living facilities for seniors, health care workers with direct patient contact, aged 70 years of age or older, or adults in Indigenous communities; (2) As vaccines against many other pathogens, it is plausible that the current standard vaccination strategy of COVID-19 is less effective in PLWH; (3) The potential burden of significant COVID-19 infection in PLWH is likely large given many PLWH are aging and have co-morbidities known to predispose to worse COVID-19 outcomes; (4) The vaccine clinical trials which include PLWH63, have stringent exclusion criteria, making results non-generalizable to many PLWH such as those with lower CD4 counts. With the rapid roll-out of COVID-19 vaccination, many PLWH will be receiving the COVID-19 vaccine. Through vaccination, the provision of the same dosage of antigen stimulation to all individuals will result in a controlled method to measure immune response in PLWH. Therefore, we propose to develop a pan-Canadian cohort of PLWH receiving a COVID-19 vaccine(s) to assess a spectrum of immune responses. We also aim to assess the safety and tolerability of the COVID-19 vaccines in PLWH. These data may provide support for the use of one vaccine product over another and for exploring alternate vaccination strategies in PLWH (i.e., increased dose or double-dose vaccination and so forth).
Cross-sectional study is to explore the impact of painful neuropathy in the feet on function in persons living with HIV (PLHIV).
This project will develop, implement, and evaluate models for use of point-of-care nucleic acid testing (POC NAT) among HIV-negative persons seeking HIV testing, PEP, and PrEP and HIV-positive persons in community and clinical settings. Study aims #1 and #2 will evaluate the sensitivity and specificity of a qualitative POC NAT in persons not known to be HIV-positive and will determine the impact of its use on PrEP uptake and persistence among persons testing HIV-negative and on time to HIV continuum of care outcomes among persons testing HIV-positive. Aim #3 will implement a POC NAT-tailored behavioral intervention to evaluate impact on time to virologic suppression among PLWH receiving ART. Aim #4 will quantify the acceptability and feasibility of implementation of POC NAT in community and clinical settings and collect cost and related data for cost-effectiveness analyses. Finally, in Aim #5, a distinct but related study will compare the sensitivity, specificity, and agreement of multiple POC NATs over a range of HIV RNA levels.
This study is to explore the effects of transcutaneous nerve stimulation (TENS) and mindfulness meditation in persons living with HIV (PLHIV) and painful neuropathy in the feet.
The trial is an open-label, multicenter, prospective, randomized trial in 2 parallel groups, evaluating at W48 the non inferiority of antiretroviral dual therapy taken 4 consecutive days per week versus antiretroviral dual therapy 7/7 days per week in HIV-1 infected patients with controlled viral load under antiretroviral dual therapy.
The purpose of this study is to determine the feasibility and impact of 28-days of monitored abstinence from cannabis use on symptoms of depression and anxiety, pain, sleep, cannabis use withdrawal, HIV viral load and biomarkers of systemic inflammation among PLWH and who use cannabis regularly (weekly or more often). This will be a single arm pilot feasibility trial involving a contingency management program to induce cannabis abstinence. Specifically, the contingency management program will provide motivational (monetary) incentives to participants who achieve biochemically verified cannabis abstinence. Over the 28-days of this pilot feasibility trial, participants will attend seven study visits. During these visits, participants will complete survey questionnaires to assess sociodemographic, psychosocial, and behavioral factors. In addition, participants will provide blood and urine specimens for testing and quantitation of HIV viral load, biomarkers of systemic inflammation and for the detection of cannabis and other drugs of abuse.
The proposed study will involve adolescent (17-24 years old) men who have sex with men (described as YMSM hereafter) who meet eligibility criteria to participate in each study. Prospective study candidates will receive a copy of the IRB-approved informed consent forms and, if they choose to participate, will provide consent before enrollment into this study. Involvement of human subjects is detailed in the Research Strategy portion of this proposal, Recruitment and Retention Plan, and Protection of Human Subjects sections. Briefly, investigators will develop and pilot a randomized controlled trial (RCT) to support HIV self-testing (HIVST) and pre-exposure prophylaxis (PrEP) uptake. Intervention content will be focused on constructs of the Information-Motivation-Behavioral Skills (IMB) model. To reduce cost and increase feasibility, investigators plan to incorporate previously developed content as much as possible-investigators see integration of this content as a major strength. Investigators will include professionally produced videos about HIV testing and PrEP and other resources including the geo-targeted directories to find clinic settings that offer HIV testing and PrEP, all of which are publicly available. Investigators believe our approach of guiding YMSM through intervention modules based on theory will help improve content retention/use and ultimately influence constructs posited to result in behavior change. Investigators foresee using multiple forms of attention-matched material, media, and programming to engage (and retain engagement) of YMSM throughout the brief single-session intervention (45-60 minutes). Intervention content is subject to change depending on feedback from focus groups, survey results, YAB feedback, and usability testing. Primary endpoints of this study include HIVST and PrEP uptake, including stage of change towards HIVST and PrEP uptake. Secondary outcomes include changes in IMB model indicators (e.g., HIV prevention knowledge).
The purpose of this study is to characterize the pharmacokinetics (PK) of understudied drugs administered to lactating women, receiving antiretroviral drugs per SOC as prescribed by their healthcare provider, and their co-enrolled infants ≤180 days of age who receive maternal breastmilk.
The purpose of this study is to learn whether having the AMP Study antibody (called VRC01) in a person's body might help their immune system control HIV better, even without HIV medication called antiretroviral therapy or ART, if they get HIV. This study will evaluate the viral and immune system responses in an Analytical Treatment Interruption (ATI), in participants who received VRC01 or placebo and got HIV while enrolled in HVTN 703/HPTN 081 (NCT02568215). Participants in this study will stop taking their HIV medication. They will stay off HIV medication unless and until the HIV levels in their blood show that their immune system is unable to control the HIV or they meet other ART re-start criteria as noted in section "Detailed Description". While they are not taking HIV medication, their HIV levels will be tested frequently, and their health will be monitored closely. This is called an analytical treatment interruption, or an ATI. An ATI is an experimental procedure that is only used in carefully monitored research.
The purpose of this study is to compare the effectiveness of two mobile health technologies (text messaging or a mobile app) designed to help people take HIV pre-exposure prophylaxis (PrEP) as directed by the clinic. PrEP is the use of a daily anti-HIV medications by HIV-negative people to help prevent HIV infection.
