Effects of Iron Loading and Iron Chelation Therapy on Innate Immunity During Human Endotoxemia
Systemic Inflammatory ProcessAnemiaIron affects immunity. However, the exact effect of iron on the innate immune response is not known. Animal data suggest that iron administration induced oxidative stress which enhances the innate immune response, whereas iron chelation has the opposite effect. The investigators tested the hypothesis that administration of iron sucrose 1.25 mg/kg augments the innate immune response, and iron chelation by deferasirox 30 mg/kg attenuates the innate immune response during human experimental endotoxemia.
Study of Gene Activity in Fat and Muscle in Diabetics and Healthy Controls
HealthyType 2 Diabetes1 moreThe aim of the present protocol is to study gene activity in fat and muscle tissue in type 2 diabetics and healthy volunteers after injection of E. coli endotoxin.We hereby hope to gain insight in some mechanisms behind the association between inflammation and insulin resistance.
Gastro-intestinal and Hormonal Responses to Systemic Inflammatory Disease
Motility DisorderCatabolic State1 moreThe aim of this study is to describe hormonal responses and changes of the gastrointestinal (GI) tract during healthy and catabolic inflammatory conditions. Participants will receive isocaloric, isonitrogenous beverages of either whey or 3-OHB+whey in a randomized crossover design during either healthy (overnight fast) or catabolic conditions (inflammation/endotoxemia + 36 h fast and bed rest).
Observe Change of Endotoxaemia and Related Mediators in Patients With Chronic Hepatitis B Virus...
Hepatitis BChronicThis study was designed for changes in endotoxaemia, endotoxin-binding factors, sICAM-1 (soluble intracellular adhesion molecule-1), and cytokines during progression of chronic HBV infection. Patients with chronic HBV infection and healthy control are included. A limulus assay was used to measure plasma endotoxin level and ELISAs were used to measure the concentrations of interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-α (TNFα), sICAM-1, and soluble CD14 (sCD14).
Probiotic Sport Study
Oxidative StressInflammation1 moreWe 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
Role Of Phospholipid Transfer Proteins (Pltp) On Endotoxemia Caused By Buccal Inflammation
Patients With Periodontal DiseaseThis 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.
Type 2 Diabetes and the Effect of Probiotics
Type 2 DiabetesHealthy1 moreInsulin-resistance in type 2 diabetes is associated with chronic inflammation. Anti-inflammatory actions might increase sensitivity to insulin. Since some probiotics have anti-inflammatory properties, ingestion of the probiotic bacteria Lactobacillus Acidophilus NCFM might increase insulin-sensitivity. The inflammatory response to endotoxin injection and the insulin-sensitivity is examined before and after four weeks ingestion of probiotics.
Cardiometabolic Benefits of Potatoes Mediated Along the Gut-Vessel Axis in Adults With Metabolic...
Cardiovascular DiseasesEndotoxemia3 moreThis study is focused on assessing potential health benefits of daily consumption of potatoes, specifically its resistant starch content (i.e. nondigestible carbohydrate), on blood vessel and gut health function in adults with metabolic syndrome. It is expected that the daily consumption of potatoes for two weeks, within a diet that follows the Dietary Guidelines for Americans, will improve blood vessel function in association with decreasing gut permeability ("leaky gut") that results in the absorption of bacterial toxins that reside in the intestine. Outcomes will therefore support dietary recommendations for potatoes to support vascular and gastrointestinal health.
The Association Between Microbiota, Endotoxaemia and the Host Obesity/ Insulin Resistance (MiPOOP...
Central ObesityThe objectives of this study are to examine the effects of ethnicity, central obesity and dietary components, on the human gut microbiome. The investigators hypothesize that these factors have an influence on the composition of the gut microbiome. Healthy subjects (n=35) provided stool samples for gut microbiome profiling using 16S rRNA sequencing and completed a dietary questionnaire. The serum samples were assayed for a panel of inflammatory cytokines. Their associations with central obesity were examined.
Cerebral Blood Flow and Metabolism During Hypoxia and Endotoxemia
HypoxiaEndotoxemia1 moreThe objective of the present protocol is to study whether a low level of oxygen in the blood will affect the immune response to as well as cerebral blood flow and metabolism during an infection and, conversely, whether the acute systemic and cerebral physiologic response to hypoxia is modified by an ongoing inflammatory response.
