Filter by:The investigators propose a pilot study using (1) MRI to assess coronary artery endothelial function, (2) brachial ultrasound to assess systemic endothelial function, (3) serum markers of inflammation and of endothelial cell function and (4) echocardiographic measures of left ventricular diastolic and systolic properties, before and following initiation of PCSK9 antibody in HIV positive subjects.
The conventional way to control HIV infection is the usage of a drug cocktail capable of suppressing the viral replication cycle, commonly known as antiretroviral therapy (ART). Despite effective ART it is not possible to eradicate HIV. The virus hides in particular cells to form the latent HIV-reservoir.[1-9] Studies that emphasise on revealing hidden reservoirs would aid in designing novel therapeutic strategies for controlling HIV infection. Molecular imaging by SPECT/CT has the potential to reveal hidden reservoirs of HIV virus that are not eliminated by currently used drugs capable of suppressing and thereby controlling the viral replication cycle in HIV infected patients. New approaches, necessary to prevent and treat HIV-1 infection, are gradually emerging. A new generation of highly potent broadly neutralizing antibodies (bN/Abs) may represent a promising approach to combating HIV-1 infection.[10] The broadly neutralizing antibody 3BNC117 antibody that can mimic human CD4 binding targeted against the HIV gp120 envelope protein has been tested in various clinical trials.[11-14] It has found to be safe and effective in reducing viraemia and to improve host humoral responses in HIV-1 infected individuals, and to have effect on viral rebound in patients who are kept off antiretroviral treatment briefly for experimental purpose. Imaging of simian immunodeficiency virus (SIV) infection by PET/CT has been successfully performed in nonhuman primates with a 64Cu-labeled SIV gp120-specific antibody called 7D3.[15] This study aims to use a similar approach in human with the 3BNC117 antibody. The 3BNC117 antibody has been successfully radiolabeled with iodine 123. The half-life of this radioisotope is appropriate for antibody imaging in nuclear medicine. Radiolabeled 123I 3BNC117 was shown to keep a good immunoreactivity for gp120. By using state of the art SPECT scanner a semi-quantitative image will be obtained. In addition, the absence of any chelator and the well known use of iodine-123 in clinic make it suitable for human intervention. No HIV imaging in human has been achieved yet, which is however fundamental to understand some key steps in the pathogenesis of HIV-induced immunodeficiency. This research opens promising opportunities for drug and vaccine development. Indeed, identification of virus reservoirs in treated patients would facilitate the development of strategies for eradicating these reservoirs or for extending latency period.
HIV persists despite antiretroviral therapy (ART) and is associated with chronic inflammation. This inflammation is thought to prevent an effective immune response against the virus and is mediated at least in part by gut epithelial permeability and microbial translocation. HIV accumulates preferentially within Th17 cells with time on ART; these memory CD4+ T cells are highly susceptible to HIV infection and are concentrated within the gut. Vitamin D promotes gut epithelial integrity in animal models and exerts anti-inflammatory effects on the human immune system including down-modulation of Th17 cell frequency. This study will evaluate whether high dose vitamin D is able to reduce immune activation and Th17 cell frequency, to improve gut barrier integrity and the gut microbiome and reduce HIV persistence in participants on long-term suppressive ART.
This is a randomised two-part Phase I study which will explore the impact of different boosting options (MVA-CN54 and recombinant CN54gp140 protein) for oral Adenovirus serotype 4 vector prime expressing HIV-1 CN54 envelope (Ad4-EnvCN54) designed to optimize systemic and mucosal antibody responses. Part 1 is exploratory and designed to select conditions capable of promoting enhanced systemic and mucosal B cell responses in a limited number of participants. Part 2 is dependent upon Part 1 and is designed to study groups selected on performance in part 1 in an expanded number of subjects. Data from both stages will be combined for safety and immunological analyses.
In a multi-center study 200 patients co-infected with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) will be treated with a fixed-dose combination pill combined of 400 mg sofosbuvir and 30, 60, or 90 mg of daclatasvir - depending on the particular antiretroviral treatment (ART) being used by the patient. The treatment duration will be 12 weeks for subjects without cirrhosis and 24 weeks for those with cirrhosis.
The study harnessed the multidisciplinary expertise of our research team to develop a brief, computer-based, alcohol reduction intervention tailored for HIV/HCV co-infected women and evaluate its efficacy. The intervention, if effective, may be an efficient and cost-effective alcohol reduction strategy, that is scalable and can be readily disseminated and integrated in clinical care at other AIDS Centres in Russia to enhance women's health and reduce HIV/HCV transmission risk.
The aim of this study is to assess the feasibility and the effects of a 6-week telerehabilitation on the three domains of the International Classification of Functioning, Disability and Health in HIV-infected patients under highly active antiretroviral therapy (HAART). HIV-infected patients were randomized either into an Endurance and Resistance Training Exercise (ERTE) group or a control (CON) group. Telerehabilitation was realized in a public fitness center, with online guidance and weekly telephone advice, 3 times per week for 6 weeks. Feasibility was determined by recruitment rate, retention rate and adverse events. Secondary outcomes were impact on body composition, inflammation and coagulation (C-reactive protein, D-dimer), physical fitness and quality of life (WHOQOL-HIV).
The primary purpose of this study is to assess safety/tolerability of 2 different prime/boost regimens containing adenovirus serotype 26 (Ad26).Mos4.HIV, Modified Vaccinia Ankara (MVA) -Mosaic or adjuvanted Mosaic and Clade C gp140 in Human immunodeficiency virus type 1 (HIV-1)-infected participants on suppressive antiretroviral treatment (ART).
The purpose of this study was to pilot test the potential for improvement in antiretroviral medication adherence of a an adapted group-based, multi-session, community-based Antiretroviral Therapy (ART) adherence and risk reduction intervention, Project ADHerence Education and Risk Evaluation (ADHERE). Project ADHERE was compared to a single-session group-based medication adherence intervention, Medication Adherence and Care Engagement (MACE). A secondary aim was to examine the impact of Project ADHERE on HIV risk behaviors (i.e., illicit drug use and unprotected sexual behavior). This study was designed to inform, design, and pilot test the two antiretroviral medication adherence interventions for HIV-infected formerly incarcerated individuals.
Kaposi sarcoma (KS) has an unpredictable course, patients with disseminated KS starting combined Antiretroviral Therapy can develop Immune Reconstitution Syndrome (IRIS), with a severe clinical presentation and high mortality (severe-IRIS-KS). The objective of this study is to evaluate the presence of Severe IRIS-KS and it´s attributable mortality in patients with AIDS and disseminated KS with the use of valganciclovir prior to the initiation of cART compared with the standard management of immediate cART initiation.
