Filter by:This project aims to assess different antiretroviral treatment strategies, optimally controlled and conventional, in relation to drug resistance and virological treatment failure. A Randomised Controlled trial (RCT) where Vietnamese HIV+ patients with CD4+ T-cells <200/ul are randomized into either enhanced treatment support (ETS) through peer supporters or The National AIDS Control Program recommended self supervised treatment (SST). The treatment strategies will be assessed and compared in relation to treatment adherence and drug resistance development with virological treatment failure as primary endpoint. The results from this project will lead to an increased knowledge in relation the impact of treatment support on adherence, virological suppression and resistance development and have an impact on HIV treatment policies in low income settings globally.
This study is to test a therapeutic HIV-1 vaccine (HIVAX™) in HIV-1 infected subjects. The safety and immune responses will be studied in vaccine recipients. The anti-viral effect of HIVAX vaccine will be monitored during a 12-week treatment interruption phase.
The PIVOT trial aims to determine whether a strategy of switching to PI monotherapy is non-inferior to continuing triple-therapy, in terms of the proportion of patients who maintain all the drug treatment options that were available to them at baseline after at least 3 years of follow-up, and to compare clinical events, safety, toxicity and health economic parameters between the two strategies.
Little is known about the clinical significance of chronic alanine aminotransferase (ALT) elevation in HIV-infected patients without hepatitis B and C coinfection. Study aim is first to evaluate the prevalence of liver fibrosis and cirrhosis in HIV-infected patients with chronic ALT elevation and no chronic viral hepatitis using non-invasive diagnostic tests and second to find associated factors with significant fibrosis and cirrhosis. In a second longitudinal part we intend to assess fibrosis progression within 1 and 3 years.
The purpose of this pilot study is to find out if taking hydroxychloroquine will decrease immune activation (stimulation of the body's defence system) in people with early HIV infection. Hydroxychloroquine is a medicine that has been used successfully for many years to treat autoimmune diseases (diseases in which the immune system causes damage to the body), e.g. lupus and rheumatoid arthritis. It is generally safe in long-term use and easily accessible. The immune system is stimulated in response to infections including HIV, so treatments that decrease immune activation may have long-term clinical benefits i.e. delay onset of treatment.
Retrospective longitudinal cohort study with 36 HIV naïve-treatment patients, who started therapy with lopinavir/ritonavir or efavirenz (LPV/r or EFZ), follow-up of 36 months. Primary endpoint: virological success (HIV RNA <50 copies/mL) in the first six months and at the end of the study.
This pilot study will assess the feasibility of using heavy water as a safe 'tracer' for biomarker studies of diseases of the brain and spinal cord, that, together, are also called the central nervous system (CNS). Heavy water, also called deuterated water or D20, is the same as normal drinking water except the hydrogen atoms have been replaced by deuterium, a naturally occurring isotope of hydrogen. In particular, this study will use heavy water to define: 1) The rate of immune cell proliferation (growth) in the cerebrospinal fluid (CSF) compared to blood. This study will be examining a particular type of immune cell called T lymphocytes. 2) This study will also examine selected molecules generated by nerve cells of the CNS to understand their rate of secretion and turnover in healthy control participants, HIV-1-infected participants and participants with a non-HIV-related neurodegenerative disease such as Parkinson's disease (PD). This study will involve the administration of heavy water orally for either seven days, 12 days or six weeks. Measurements will be taken by lumbar puncture (LP, also known as a spinal tap). Blood (approximately five tablespoons per visit) will also be obtained at each of the lumbar puncture appointments. If this method can be used to establish the rates of immune cell turnover and the production rates of neuronal molecules using cerebrospinal fluid, it will provide unique data that is important to understand chronic neurodegenerative conditions, like PD, and to measure responses to targeted therapies. Hypothesis: 1. D2O, administered orally, can be used to measure the proliferation rates of CSF T cells (and, eventually, of their major phenotypic subsets). 2. D2O can be used to assess the turnover and production rates of CNS constituents that are normally or pathologically shed or secreted into the CSF, including (eventually): cargo molecules transported specifically in neurons in the CNS, such as chromogranin-A and -B, neuregulin-1 (specifically the extracellular secreted ectodomain of neuronal differentiation factor (NDF) isoform type α1, α2, β1, and the acetylcholine receptor inducing activity isoform (ARIA), secreted amyloid precursor protein (sAPP), alpha-synuclein; and APP metabolites amyloid beta (Aβ) 41 and 42.
The purpose of this study is to determine if Maraviroc administration can decrease IRIS incidence in HIV infected patients initiating ARV therapy.
High levels of HIV infection within blood monocyte/macrophages (a type of white cells in the bloodstream) increases risk of dementia in HIV-infected individuals. Maraviroc (Selzentry) is a HIV medication that works by blocking the entry of HIV in cells including monocytes/macrophages that use a receptor called CCR5. The study hypothesis is that the addition of Maraviroc to a HIV antiretroviral regimen in HIV-infected individuals with high levels of HIV-infected monocyte/macrophages will lead to a decrease in the levels of infected monocyte/macrophages and to decrease in brain inflammation as studied by magnetic resonance spectroscopy (MRS, a form of MRI study).
The purpose of this study is to provide etravirine (ETR) through this trial until participants can be switched to locally available ETR-based treatment regimens (that is, commercially available and reimbursed, or accessible through another source [example, access program or government program]), or local standard of care, as appropriate.
