View clinical trials related to Systemic Inflammation.
Filter by:Background: Inflammatory conditions can cause symptoms like fevers, arthritis, and rash. Systemic juvenile idiopathic arthritis (sJIA) is one of these conditions. So is adult-onset Still s disease (AOSD). Their causes are unknown. Researchers want to learn more about these conditions. This includes genetic changes and environmental factors. Objective: To study sJIA and AOSD in children and adults over time. Eligibility: People with known or suspected sJIA, AOSD, or similar inflammatory condition Design: Participants will be screened with a phone call. Participants will have 1 visit. It may be outpatient or they may be admitted to the clinic. The visit may last up to 5 days. Participants will have: - Medical history - Physical exam - Musculoskeletal exam - Questions about overall health and quality of life, disease activity, functional status, and cognitive ability. Participants may also have: - Pictures taken of their skin, joints, or spine - Blood, urine, and stool tests - Scans or X-rays of joints with arthritis - Chest X-ray - Heart tests - Skin biopsy. The skin will be numbed. The top layers of a small area will be scraped off. Participants who have a joint aspiration may provide a fluid sample. The joint will be prepared, then fluid is removed by needle. A corticosteroid may be injected. Participants who have a bone marrow biopsy may provide sample cells. Participants may be seen by NIH specialists. Members of the participant s family and healthy volunteers may give blood or saliva samples for genetic testing. Participants may repeat some study tests every 6 months.
Previous research shows that a diet high in fat has harmful effects on gut health. This increases the chance of developing obesity-related diseases (such as type 2 diabetes) and disrupts cognition and mood. Research has suggested that gut health can be improved by taking certain supplements, including resveratrol (a polyphenol found primarily in red grape skins). Resveratrol has also been shown to improve brain blood flow and possibly brain function - however, there is limited research studying this. This study will investigate the effects of 12 weeks daily consumption of resveratrol on cognitive function, cerebral blood flow, gut microbiota and systemic inflammation in overweight and obese healthy adults.
Metabolic syndrome represents a major health burden worldwide affecting 20-30% of the population. This clustering of abnormalities that confers an increased risk of cardiovascular disease and type 2 diabetes mellitus, is the hallmark of "unhealthy" aging in longevity studies. Preventive strategies have so far failed since they have focused mainly on reducing caloric intake, ignoring the metabolic dysfunction in the aging body. The growing importance of the gut microbiota in all aspects of human health is clear, and unlike our genomes is potentially highly modifiable and tightly related to metabolic and immune efficiency, energy and fatty acid metabolism and satiety hormones. The investigators and others have reported that higher microbiome diversity correlates with significantly lower long-term risk of weight gain and metabolic syndrome. The investigators have recently shown that serum levels of omega-3 fatty acids correlate with higher microbiome diversity, and increased abundance of bacteria that produce butyrate are linked to lower inflammation of the gut. The investigators therefore propose to carry out a proof of concept nutritional intervention study in the TwinsUK cohort. The TwinsUK sample is probably the most detailed omic and phenotypic resource in the world and is ideal for this study. The mechanisms that result in improved microbiome composition and diversity will be explored in a highly focused novel interventional study hypothesizing that key fatty acid pathways are crucially involved in the link between diet, microbiome, immune phenotypes and metabolic syndrome. The specific objectives are to measure changes in gut microbiome composition in response to fibre supplementation compared to omega-3 fatty acid supplementation. The study will measure faecal metabolites relevant to fatty acid metabolism (short chain fatty acids), the abundance of microbial species linked to higher or lower inflammation and immune cell phenotypes to unravel the link between inflammation, diet and metabolic syndrome. There is a real lack of good diet intervention studies in this field and if successful this trial will pave the way to funding a wide variety of other diet intervention studies.
This study examine the effects of very low carbohydrate diet (in which the calories requirements are mostly from fat) to the level of systemic inflammation (measured by Glasgow Prognostic Score), serum lactate and TNF Alpha levels
Study should demonstrate that alkaline phosphatase reduces the incidence and extent of acute kidney injury after cardiopulmonary bypass (CPB) as defined by the AKIN criteria.
The purpose of this research study is to explore the effects of fermented papaya preparation (FPP) on whole body inflammation, physical function, fatigue, and health-related quality of life. The investigators will conduct a double-blind, randomized, placebo-controlled pilot study on FPP in older adults. If FPP is found to have a beneficial impact on systematic inflammation in this study population (adults aged 70-100 years old), then this supplement may be a potential treatment option to combat aging.
This study is focused on the effects of HEPA filtration to reduce exposures to combustion-derived air pollution (CDAP). Specifically, the study will evaluate the health benefits of HEPA filters and compare the cardiovascular toxicity of two major sources of CDAP, specifically traffic and residential wood combustion. Specifically, the purpose of this study is to evaluate the ability of portable high efficiency particle air (HEPA) filters to reduce exposures to PM2.5 and air pollution indoors and to improve subclinical indicators of microvascular function and systemic inflammation among healthy adult participants. The investigators hypothesize that HEPA filter use will help decrease indoor concentrations of CDAP thereby helping to mitigate the associated cardiovascular risks.
Studies showed that infusion or injection of drugs and fluids results in introduction of microparticles into the bloodstream. These microparticles may cause organ damage and stimulate the immune system thus aggravating the underlying disease. Given that critically ill patients are characteristically suffering from a high disease severity and receive large amounts of fluids and drugs, they may be at particular risk of harm by these microparticles. In-line microfilters have been shown to clear microparticles from intravenous drugs and solutions. The investigators hypothesize that use of in-line microfilters reduce the days with the systemic inflammatory response syndrome in adult critically ill patients.
Air pollution is linked to respiratory and cardiovascular disease. Wood smoke is a common air in many parts of the world and previous studies indicate that wood smoke induce oxidative stress in the respiratory tract. It is not determined how different types of biomass combustion affect human health. In this study the investigators plan to investigate how inhalation of wood smoke and pellets smoke affect respiratory and cardiovascular health.
The purpose of this study is to evaluate the ability of portable high efficiency particle air (HEPA) filters to reduce exposures to PM2.5 and woodsmoke air pollution indoors and to improve subclinical indicators of microvascular function, systemic inflammation, and oxidative stress among healthy adult participants.
