Filter by:In a wide range of auto-inflammatory and infectious diseases attenuation of the immune response could be beneficial. Remote ischemic preconditioning (RIPC) has been identified as a means of protecting patients undergoing cardiac surgery from perioperative myocardial ischemic damage. This protection can be divided in a `first window of protection` directly after preconditioning and a `second window` that protects patients 12-48 hour after preconditioning. Repeated RIPC might have additional value, possibly by combining beneficial effects of the first and second windows of protection. The mechanisms behind these effects are under investigation, but attenuation of the inflammatory response is a major candidate. However, this has not yet been demonstrated in the setting of systemic inflammation in humans in vivo. This study aims to investigate the effects of (repeated) ischemic preconditioning on inflammation during human endotoxemia.
The purpose of this study was to determine the effect of different dietary fats (saturated or unsaturated) on postprandial endotoxemia and systemic low grade acute inflammation. The investigators hypothesized that meals rich in saturated or n-6 fatty acids would increase postprandial endotoxemia but meals high in n-3 fatty acids would decrease postprandial endotoxemia.Participants were recruited via email and randomized to treatment meal in this single-blind, cross-over study. Each test session participants reported to the laboratory right away in the morning. An indwelling catheter was inserted into the participant non-dominant arm by a qualified nurse and a baseline blood draw was taken. The participant was then provided with one of four test meals (a porridge-type meal containing a different dietary fat), which they ate in entirety within 15 minutes. The participants remained in the laboratory for the next five and a half hours and were not allowed to consume any food or drink except water. During this time, further blood draws were taken at intervals of one hour for a total of five hours after the consumption of the test meal. Collected blood was processed on-site and the serum fraction collected and tested for endotoxin, inflammatory biomarkers, and metabolites.
This is an exploratory study on the metabolic endotoxemia associated with type 2 diabetes. The investigators will measure systemic endotoxin level and lipid level after ingestion of high fat diet to evaluate the effect of gemigliptin, a DPP-4 inhibitor, on metabolic endotoxemia and lipemia induced by high fat diet.
The purpose of this study is to determine whether treatment with antibiotics, which harm the gut flora, causes the immune system to be less effective.
Oxygen is a widely available gas that is cheap, easy to get and extensively used in medicine. From animal studies it has become apparent that increasing or lowering the degree of oxygen in the blood, the inflammatory response can be altered. We will investigate of this is also true in humans by increasing, lowering or keeping oxygen levels normal while giving healthy subjects a short inflammatory stimulus.
This is a transversal double-centre study. Patients will be recruited from outpatient consultations. They will have buccal inflammation caused by periodontal disease (frequent oral infections, mostly with GRAM (-) bacteria). Three groups of 80 patients, corresponding to slight, moderate and severe periodontal disease, will be formed according to the results of radiological and clinical examinations.
Excessive inflammation is associated with tissue damage caused by over-activation of the innate immune system. This can range from mild disease to extreme conditions, such as multiple organ dysfunction syndrome (MODS) and acute respiratory distress (ARDS). In marked contrast to adaptive immunity which is very sensitive to immune modulators such as steroids, the innate immune system cannot be sufficiently targeted by currently available anti-inflammatory drugs. The investigators hypothesize that pre-treatment with C1-esterase inhibitor in a human endotoxemia model can modulate the innate immune response. In this study, human endotoxemia will be used as a model for inflammation. Subjects will, prior to endotoxin administration, receive C1 esterase inhibitor or placebo. Blood will be sampled to determine the levels of markers of the innate immune response.
HIV-infected people can have an increase in inflammation in their body organs, even after taking anti-HIV medicines. Sevelamer carbonate is used to bind phosphate in dialysis patients. It can also bind endotoxin in the gut and lowers endotoxin levels in the blood of dialysis patients. Sevelamer carbonate decreases the inflammation endotoxin causes in dialysis patients. A5296 is a phase II, single-arm study to evaluate the effect of 8 weeks of sevelamer carbonate administration on markers of microbial translocation and T-cell activation in the blood in chronically HIV-infected subjects not receiving ART.
The purpose of this study is to assess the effect of the anti-hepcidin Spiegelmer NOX-H94 on iron homeostasis during systemic inflammation induced by endotoxin. In the human endotoxemia model, intravenously administered lipopolysaccharide elicits an inflammatory response with release of pro-inflammatory cytokines, such as IL-6 and TNF-alfa, with subsequent induction of hepcidin. As a consequence of hepcidin induction, serum iron concentrations decrease. This study in healthy subjects investigates the capacity of NOX-H94 to inactivate hepcidin and to prevent serum iron decrease in a pathophysiological model prior to studying the efficacy of NOX-H94 in patients with anemia of chronic disease.
We investigate the impact of a probiotic-based dietary supplement on oxidative stress and endotoxemia before and after strenuous exercise. Hypotheses (H1): - Supplementation has an influence on oxidative stress parameters before and post exercise - Supplementation has an influence on parameters of endotoxemia and inflammation before and post exercise - Strenuous exercise has an influence on parameters of oxidative stress, inflammation and endotoxemia
