Filter by:A total of 30 subjects with moderate to severe atopic dermatitis. Thirty subjects without AD matched for sex, age and coronary artery disease risk factor with the AD subjects will also be included. All subjects will undergo the following imaging procedures: a 18FDG-PET to quantify vascular inflammation in the ascending aorta and carotids and a MDCT to calculate the Agatston score. Skin and blood biomarkers will also be assessed.
Vascular inflammation, a central feature of atherosclerosis, participates in the initiation, perpetuation and instability of plaques. Multiple clinical trials of cholesterol lowering therapy with statins have demonstrated that reductions in atherosclerotic cardiovascular disease (CVD) events are associated with reductions in both LDL cholesterol (LDL-C) and the systemic inflammatory mediator C-reactive protein (CRP). The Cardiovascular Inflammation Reduction Trial (CIRT) investigates if an anti-inflammatory agent commonly used in rheumatoid arthritis (low dose methotrexate (LDM)) can reduce CV morbidity and mortality among patients with a prior myocardial infarction or angiographically demonstrated multivessel coronary artery disease (GCO#13-1467). In this ancillary CIRT imaging study, the investigators propose to use this well validated approach by non-invasive serial FDG-PET/CT imaging in a subset of patients enrolled in the main CIRT trial to directly visualize vascular inflammation. Once the subjects are enrolled in the main CIRT trial, baseline imaging will be done and follow up imaging will be done approximately 8 months after the baseline imaging. 18FDG-PET imaging data will be acquired, analyzed centrally and results incorporated into the main CIRT database. The investigators hypothesize that LDM treatment will result in a significant decrease in plaque inflammation as measured by 18-FDG-PET/CT after 8 months as compared to placebo.
The purpose of this study is to compare the effects of ticagrelor and clopidogrel on endothelial dysfunction and vascular inflammation Ticagrelor will lead to beneficial pleiotropic effects compared with treatment with clopidogrel in patients receiving a drug-eluting stents (DES) during percutaneous coronary intervention (PCI) for non-ST-segment acute coronary syndrome (NSTE-ACS) beyond 1 month after the index event. Ticagrelor treatment will improve percent flow-mediated dilation (FMD) values and reduces inflammatory gene expression on peripheral blood mononuclear cells.
Psoriasis is an inflammatory disease involving the skin, the joints and the vascular compartment. The mechanisms linking inflammation in the skin and joints and in the vascular walls are poorly understood. One hypothesis for the increase in vascular inflammation observed in patients with psoriasis involves circulating pro-inflammatory cytokines. Patients with psoriasis have an increase in serum levels of tumor necrosis factor alpha (TNF-alpha), Interleukin-17 (IL-17), IL-22, IL-6 as well as a the chemokine S100A913. It is possible that one of those cytokines/chemokine induces vascular inflammation in the vascular compartment. The purpose of this cross sectional retrospective study is to highlight the correlation between vascular wall inflammation using 18F-2-fluoro-2-deoxy-D-glucose - Positron Emission Tomography (FDG-PET) fluorodeoxyglucose technology and pro-inflammatory cytokines/chemokine.
The primary goal of this preliminary project is to study the effect of etanercept, a medicine approved by Health Canada for the treatment of rheumatoid arthritis, on the inflammation of certain blood vessels. In particular, the inflammation of the aorta and the carotid arteries will be studied. This study's goal is to determine if etanercept (that blocks TNF (tissue necrosis factor) alpha) could have an effect on blood vessel inflammation. As well, the information from this study will be used to determine the number of patients to recruit in a future study. This study will evaluate the effect of etanercept on 10 patients with rheumatoid arthritis at one rheumatology clinic in Montreal. The 10 patients will be recruited at the Montreal Rheumatology Institute (Institut de Rhumatologie de Montréal) and the images of the blood vessels taken at a medical imaging center will be analyzed by the Montreal Heart Institute. To evaluate vascular inflammation subjects will undergo a PET scan (Positron Emission Tomography).
Examination of the effect of Linagliptin versus placebo for 6 months on vascular inflammation of the carotic artery and on abdominal adipose tissue inflammation in patients with diabetes mellitus type 2. The effect will be assessed by FDG-PET scan. Furthermore the effect of Linagliptin on the vessel wall volume of the carotid artery will be assessed by MRI scan and biomarkers of vascular inflammation will be analyzed in blood samples.
This study is a double-blinded randomized multicenter placebo controlled trial to determine the effect of adalimumab on vascular inflammation (ascending aorta and carotides) in patients with moderate to severe psoriasis.
This study is to determine the effect of adalimumab on inflammation of blood vessels that could lead to heart attack in patients with psoriasis. Changes to the carotid artery and ascending aorta will be evaluated in patients treated with adalimumab (systemic treatment) and compared against patients treated with a topical treatment that does not affect the entire body.
