Active clinical trials for "Inflammation"

Blood sample is prospectively taken from consecutive patients underwent coronary angiogram in our center, after getting informed consent from the patients. Serum level of advanced glycation end products (AGEs) was measured and the clinical features of patients (including angiographic results) were entered into our database. Clinical follow-up was performed for all patients, and the relationship between AGEs and paitents' outcome were analyzed. Further intervention will be adjusted according to the results,including clinical and basic research in lab.

The purpose of this study is to determine whether the daily administration of a synbiotic (oligofructose and Bifidobacterium animalis subsp. lactis Bb12) for six weeks contributes to improve the glucose tolerance and the low grade inflammation (as reflected as the plasmatic concentrations of ultrasensitive CRP, IL-6, sCD14 and LPS-binding protein) in obese subjects.

Subproject 1: Optimize prevention after acute coronary syndromes (ACS) by improving caregiver and patient education (http://elips.hug-ge.ch/eng/index_eng2.htm) Subproject 2: Discover novel genomic biomarkers of ACS in leukocyte subsets by means of analyzing gene expression profiles and function Subproject 3: Evaluate novel diagnostic and prognostic biomarkers in soluble form in blood/plasma and urine Subproject 5: Visualize the vulnerable plaque using intravascular ultrasound/optical coherence tomography (IVUS/OCT) and correlate with outcome and biomarkers Subproject 7: Characterize the effects of inflammation on progenitor/stem cell-mediated repair after ACS by means of analyzing gene expression profiles and function

The current knowledge of the pathophysiology of allergic contact dermatitis is based on the murine model. In this model, CD8+ T cells are effector cells, and CD4+ T cells regulate the response by limiting the expansion of CD8+ T cells. The goal of this study is to characterize the pathophysiology of contact dermatitis, with patients allergic to para-phenylenediamine (PPD). We suppose that the CD8+ T cells are the effectors of the allergic contact dermatitis, although the regulator cells belong to the LT CD4+ population. We will test our hypothesis on blood samples, and cutaneous biopsies of patients allergic to PPD.

Rationale: Aneurysm development, progression and rupture are characterised by extensive inflammation, dominated by the infiltration of T-cells, B-cells and macrophages. Recent studies into the pathophysiology of aneurysm wall degradation suggest a close relation between increased mechanical stress and the local activation of infiltrated lymphocytes and macrophages. The non-invasive detection of aneurysm wall inflammation, using 18-fluorodeoxyglucose positron emission tomography (FDG-PET) might therefore provide valuable information on the extend of the disease and could clarify the role of mechanical stress on the propagation of aneurysm wall inflammation. Objective: Correlation of FDG uptake and in vitro aneurysm wall tensile strength. (primary objective). The effect of aneurysm sac depressurisation, after endovascular aneurysm repair, on aneurysm wall inflammation (secondary objective). Study design: Observational case series (pilot). Study population: Patients scheduled for conventional (open) and endovascular aneurysm repair. Main study parameters: Standard uptake value (SUV) measurements to asses FDG uptake in the aneurysm wall and in vitro aneurysm wall strength (N/mm). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Patients scheduled for conventional (open) or endovascular aneurysm repair are admitted to the hospital the day before surgery. At that point all patients will be evaluated using FDG-PET. Although intake of sugar-free liquids is permitted, glucose intake is restricted 6 hours prior to FDG-PET imaging. One hour after intravenous injection of 200-220 MBq FDG, whole body emission and transmission images will be acquired. To determine inflammation markers ( e.g. CRP), blood and urine samples will be collected prior to the operation and again 6 weeks after surgery. For in vitro aneurysm wall tensile strength testing wall specimens will be harvested during conventional aneurysm repair.

prospective longitudinal measurements of nutritional status parameters (body composition by BIA, anthropometry and biochemical indexes), inflammatory response (CRP, inflammatory cytokines (IL-1, IL-6, IL-10),IGF-1, leptin and NOx blood levels) and morbidity and mortality data collection over 2 year period in patients receiving chronic hemodialysis.

To determine the plasma levels of mtDNA in ICU department patients with and without sepsis and evaluate their association with severity, systemic inflammation and outcomes. Plasma from control, septic and severe septic patients will be collected. The level of mtDNA and systemic cytokine will be measured.

This study will include 100 patients with Type 1 and Type 2 diabetes, split into 2 groups of 50 patients according to their behaviour type, and their adaptation to different factors of stress encountered in their lives: the first group will consist of patients with a characteristic Type A behaviour profile, that is to say patients with a "proactive, impatient" behaviour pattern the second group will consist of patients with a characteristic Type B behaviour profile that is to say patients with a "calm, slow" behaviour pattern The objective is to know if the different behaviour patterns are associated with distinct biological markers likely to influence the evolution of the diabetes. Participation in this study will be approximately 1h30, patients will participate ONCE ONLY: they will answer simple questions about their disease and then complete 3 questionnaires each with 14 items. they will meet a clinical psychologist for an interview lasting approximately 45 minutes recorded on an audio recorder. The consultation will be used to seek links between the psyche and the disease. they will provide one blood sample of 12 ml (equivalent to a soup spoon) drawn in the morning.

In this study, the investigators will investigate and characterize acute medical patients in order to optimize patient courses in the acute care departments, especially with regard to polypharmacy and undernourishment. In addition, the investigators will investigate underlying immunological mechanisms of chronic inflammation and biological aging in this population to improve the current knowledge and possibilities for preventing chronic diseases and acute hospitalization.

The purpose of this study is to explore the effect of preoperative inflammation-based scores on postoperative morbidity and mortality for laparoscopic gastrectomy.
