256 Clinical Trials for Inflammation
The research aims to understand how a specific type of medication called Sodium-glucose co-transporter 2 (SGLT2) inhibitors affect cardiorenal inflammation.
This is a randomized, investigator-blinded, self-controlled pilot study of the physiologic response to topical moisturizers among older adults with dry skin. The overarching hypothesis is that skin barrier decline is an important source of chronic inflammation, and that skin barrier restoration with moisturizers can reduce serum biomarkers of inflammation. The primary objective is to determine the feasibility for a larger trial, and the secondary objectives are to determine the extent to which measures of serum inflammation, skin barrier function, and the skin microbiome change in response to moisturizers. Participants will be asked to apply one of two topical moisturizers that are widely available over the counter in the US (Vaseline® 100% pure petroleum jelly or CeraVe® moisturizing cream) once daily for 4 weeks to the front of the torso, buttocks, arms, and legs. Subjects will act as their own control (i.e. they will be asked to apply the study moisturizer they are randomized to for one intervention period (4 weeks) and not to apply topical moisturizers for the other 4- week intervention period). Participants will be randomized in a 1:1:1:1 ratio to one of 4 treatment groups: i. no intervention then CeraVe; ii. CeraVe then no intervention; iii. no intervention then Vaseline; iv. Vaseline then no intervention. At each visit (baseline, week 4, and week 8), participants will undergo skin barrier testing, skin microbiome sampling, and phlebotomy to measure serum inflammatory markers.
This study aims to investigate the impact of various healthy diets, specifically a modified plant-based Mediterranean diet, on the gut microbiome and overall well-being post-colonoscopy. The investigators hypothesize that certain diets can positively influence gut bacteria, reducing inflammation and enhancing metabolic signals. To explore this, they will utilize metagenomic testing on stool samples to analyze the DNA of gut microorganisms. Additionally, they will conduct immune profiling on serum samples and perform metabolomic analysis to comprehensively evaluate the diet-induced changes in immune response and metabolic pathways. This multi-faceted approach will help them understand how dietary changes affect the composition and function of the gut microbiome, immune function, and overall metabolism.
The goal of this observational study is to learn about inflammation in those with relapsing remitting Multiple Sclerosis (MS). The main questions it aims to answer are: * How does abnormal neural inflammation compare to cellular and molecular inflammation in MS? * Once treated, why does abnormal inflammation persist?
To determine the effect of early metoprolol administration after non-traumatic subarachnoid hemorrhage (SAH).
The use of electronic nicotine delivery systems, or e-cigarettes - colloquially referred to as "vaping" - in the United States has increased exponentially since their introduction to the US market in 2007. Prevalence of ever and current e-cigarette use is highest among teenagers and young adults with 16-28% of this population having reported vaping. While the majority of e-cigarette users are current tobacco smokers, 32.5% of current e-cigarette users are never- or former-smokers, representing a growing population of young adults who exclusively vape. While e-cigarettes have been marketed as a safer alternative to tobacco cigarettes, clinical studies examining these claims are limited. Cardiovascular disease (CVD) is the primary cause of premature death among tobacco cigarette smokers and reductions in vascular endothelial function, a significant predictor of future CVD, are detectible in otherwise healthy young adults who smoke. Despite the explosion in e-cigarette use among young adults, the health effects - especially the effects on mechanisms of vascular function - of these devices remain relatively unexplored. The purpose of this study is to directly asses the mechanistic role of inflammation in this dysfunction.
This study is a mechanistic randomized controlled trial that investigates whether inhibition of tumor necrosis factor signaling via intravenous infusion of infliximab improves psychomotor speed and executive functioning in depressed individuals who exhibit an inflammatory phenotype.
The purpose of this research study is to determine the effectiveness of low dose colchicine (LoDoCo) on measures of exercise capacity, physical function, frailty, and quality of life, among patients with heart failure with chronic stable preserved ejection fraction (HFpEF) and systemic inflammation. The use of LoDoCo in this study is considered investigational as it has not been approved by the Food and Drug Administration (FDA) for the treatment of exercise capacity in patients with HFpEF. Participants will undergo a 1-day screening that includes a blood draw and physical examination. If deemed eligible for the study, participants will undergo a baseline visit within 2 weeks of screening visit that includes physical examination, exercise testing, echocardiography and completion of quality-of-life surveys. Participants will also be randomized at this visit (randomly assigned to a group) to receive either LoDoCo or placebo (inactive substance) for 3 months. Participants will be called back at 3 months for repeat physical examination, blood draws, echocardiography, exercise testing and completion of quality-of-life surveys. Each visit will take about 3 hours. Total study duration is about 3 months.
The goal of this clinical trial is to learn about the effects of inflammation-lowering therapy on mobility and disability in older adults. The main questions it aims to answer are: * Will therapy improve walking speed/pace? * Will therapy improve levels of blood inflammation markers and other indicators of physical, cognitive and immune function? Participants will be asked to receive injections of drug or placebo every 4 weeks for 24 weeks. They will also be asked to undergo testing that assesses physical function, thinking ability and brain health, breathing capacity, and blood vessel stiffness, and will have blood samples collected to measure immune function and to create a bank of samples for future testing. Comparisons will be made between those who receive drug and those who receive placebo.
To determine if coating miniscrews with K21 would increase the success rate of orthodontic miniscrews by reducing adjacent tissue inflammation.
The investigator will study the origin of fungal translocation in HIV, its relationship to the mycobiome, and its relationship to lung function and inflammation. Supported by the preliminary data and published studies, this project is based on the premise that circulating BDG derived from microbial translocation stimulates inflammation and worsens lung function in PWH. Chronic obstructive pulmonary disease (COPD) is a significant public health problem with few therapies that modify disease trajectory. COPD is a leading cause of mortality in the United States associated with increased morbidity and healthcare costs. Long-acting bronchodilators and inhaled corticosteroids are mainstays of therapy that control symptoms and reduce acute exacerbation frequency, but do not have a significant impact on mortality or lung function trajectory. The National Heart, Lung, and Blood Institute's COPD National Action Plan focuses on the critical need for research to characterize COPD risk factors and disease mechanisms in order to improve the understanding of causes and progression of disease. The ultimate goal is to provide precision therapy to appropriate patient subgroups to preserve health or arrest disease progression. Microbial organisms in the gut may have a profound effect on lung disease. The role of the gut-lung axis, defined as the cross-talk between gut microbiota and the lungs, in the pathogenesis of chronic respiratory diseases is emerging as an area of interest. Perturbations of gut microbiota characterized by low microbial diversity and changes in microbiota abundance are linked to childhood asthma risk, airflow obstruction in adult asthma, and severe lung dysfunction in cystic fibrosis. Studies in animals show that both a high fiber diet that modulates gut microbiota and an abundance of beneficial bacterial strains attenuate inflammation, emphysema, and COPD development in response to cigarette smoke exposure in murine models. In humans, recent investigations show differences in the gut microbial communities between COPD patients and healthy individuals as well as shifts in the gut microbiome with acute exacerbations of COPD.
The purpose of this study is to use an experimental inflammatory challenge to examine whether older adults with symptoms of anxiety experience loss of pleasure or loss of motivation when they are exposed to inflammation. Loss of pleasure or loss of motivation will be evaluated using self-report questionnaires, computer tasks, and during a brain scan.
Dietary incorporation of pulse crops may be an effective way to lower unhealthy elevations in serum bile acids. These elevations play a direct role in promoting obesity-related diseases estimated to be present in about one third of the US adult population, including non-alcoholic fatty liver disease and type 2 diabetes. The overarching hypothesis for this study is that pulse consumption increases bile acid secretion and excretion, which will decrease toxicity linked to excess accumulation of bile in the liver, improve metabolism, and lower resulting levels of bile acids in the serum. In direct alignment with the USDA-AFRI Food, Safety, Nutrition, and Health priority to address obesity and related chronic disease with increased fruit and vegetable consumption and also with the American Pulse Association call to investigate the impact of regular pulse consumption on human physical well- being, the long-term research goal of this study is to establish effective and practical therapeutic strategies utilizing dietary incorporation of pulse crops to prevent or reverse obesity driven diseases. The specific objectives in this proposal are to: 1. determine the impact of acute lentil ingestion on serum postprandial bile acid responses and composition in a human cohort with obesity, and 2. determine the impact of daily lentil consumption for 12 weeks on serum fasting and postprandial bile acid concentrations and composition in an overweight or obese cohort with elevated postprandial triglycerides. This proposal is being submitted in response to the American Pulse Association commodity board sponsored topic of investigating the impact pulse crop consumption on health.
The purpose of this study is to better understand the underlying mechanisms associated with elevated cardiovascular disease risk in women with endometriosis, and to measure the effectiveness of emerging endometriosis treatments on outcomes specific to cardiovascular dysfunction. Epidemiologic data demonstrate a clear association between endometriosis, reproductive risk factors, inflammation and cardiovascular (CV) risk. Circulating factors, low-density lipoprotein (LDL) and oxidized LDL (oxLDL), are two of many biomarkers of cardiovascular and inflammatory disease of endometriosis. An important signaling mechanism through which circulating LDL and oxLDL act is the lectin-like oxidized LDL receptor (LOX-1). LOX-1 signal transduction functionally results in pronounced endothelial dysfunction, a hallmark of CV. The investigators hypothesis that one factor mediating the elevated risk of cardiovascular disease in endometriosis is systemic inflammation and activation of LOX-1 receptor mechanisms.
Background: About 40 percent of adults and 20 percent of adolescents in the U.S. have a body mass index over 30 kg/m2. Being overweight may lead to a state of low-level inflammation. This may cause health problems. Researchers want to see if an anti-inflammatory medicine can help. Objective: To learn if colchicine can improve metabolism in people who have high body weight, increased inflammation, and high insulin in the blood but who have not yet developed high blood sugar. Eligibility: People aged 12 and older with high body weight who may have increased inflammation and high insulin in the blood. Healthy adult volunteers are also needed. Design: Participants will be screened with the following: Medical history Physical exam Fasting blood tests Urine tests Electrocardiogram Dual energy x-ray absorptiometry (They will lie on a table while a camera passes over their body.) Stool sample and 24-hour food diary (optional) Participants will have 3 study visits and 3 phone check-ins. At visits, they will repeat some screening tests. Healthy volunteers will have the baseline visit only. They will not get the study drug. At the baseline visit, participants will have an Oral Glucose Tolerance Test (OGTT). For this, they will drink a sweet liquid and then give blood samples. They will get a 12-week supply of the study drug or placebo to take daily by mouth. Participants will have study visits 6 weeks and 12 weeks after they started taking the study drug. At the 12-week visit, they will repeat the OGTT. Participation will last for 3 (Omega) to 4 months. ...
The human immune system is designed to protect individuals from external sources of infection and internal cell mutation. It works effectively and efficiently until inflammation disturbs its functioning. Once compromised by inflammation, the immune system loses its capacity to recognize antigens and dependably defend the body against disease and illness. When COVID-19 invades humans, it causes an immune-storm (cytokine-storm) that can directly damage the organ(s), leading to death. The virus is an antigen - a trigger - but it is not the actual reason that causes organ failure and death; instead, it is the body's over immune reaction that is the cause. In attempting to protect the body, the immune system overreacts to the antigen, which includes the infected cells, which causes a cytokine-storm, and the subsequent and rapid shut down of the infected individual's organ(s)' structure, leaving the body without sufficient strength or time to fight back. When the medical herbs join the body, it can slow down the immune reaction. Medical herbs benefit the physical body; they protect the cells and organism structure and mediate the immune response, allowing the T cells to kill the virus (mutated or not) internally. Such success has been achieved by the All Natural Medicine Clinic during pre-clinical trials. This clinical study's goal is to demonstrate that the immune system can be rebuilt and retrained, using natural medicine (i.e., medical herbs), to kill the virus without causing the immune storm, and to explore the mechanism by which these medical herbs, which have been used for thousands of years for healing, achieve results.
This study aims to evaluate the effect of 8 weeks of a stress reduction intervention on atherosclerotic plaque inflammation in adults with stable coronary artery disease, as quantified by positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG) in individuals with increased psychosocial stress.
A randomized, double-blind, crossover dietary intervention trial will test the effects of 4 weeks of daily honey-flavored yogurt intake on markers of inflammation (Th17 cytokines) and oxidative stress (NOX2, UA, RSNO) and associative changes with microbial derived metabolites (SCFAs, BAs, ellagitannins), metabolism and the fecal microbiome. The above suite of selected markers will capture diet-induced systemic changes in inflammation and oxidative stress, while assessing associated microbial changes.
Obesity affects over one third of US adults (\>72 million, with BMI ≥30 kg/m2), and the proportion of US adults with BMI ≥40 kg/m2 has doubled in the last 20 years. Obesity is associated with increased mortality through its linkage to comorbidities including diabetes, hypertension, dyslipidemia, osteoarthritis, sleep apnea and psychosocial disturbances. Given its prevalence, impact on morbidity and mortality, and economic cost, limiting the spread of obesity and its consequences is one of the most important problems of our time. In this proposed study, investigators will recruit participants from a wide range of body mass index (BMI), ethnicity and Diabetes risk to collect data and blood, stool and adipose tissue samples in the San Francisco bay area.
Asthma is a heterogeneous disorder in which multiple potential inflammatory pathways contribute to airway obstruction. The biological basis for airway inflammation is the subject of intensive investigation. This work is designed to identify airway factors that are responsible for recruiting cells and associate their airway presence with atopy and asthma.
The study is a Phase 2, multi-center, randomized, double-blind, placebo-controlled study to evaluate the effects of tibulizumab over 16 weeks (Period 1) in adults with hidradenitis suppurativa, followed by a 16-week open-label extension period in which all participants will receive tibulizumab (Period 2)
The purpose of this research study is to evaluate what type of treatment will be beneficial for people with Crohn's disease and difficult to treat inflammation in the small bowel. Current therapies are used to control the inflammation due to Crohn's disease in your digestive tract. In some patients, those therapies are not sufficient to fully treat the disease. This objective of this study is to evaluate the efficacy of a different type of therapy, tirzepatide, that may promote healing of the affected intestinal segment. To evaluate the efficacy of this medication, a member of the research team will ask patients questions about how they feel and observe whether this medication heals the their bowel at colonoscopy. A member of the research team will also use blood samples, stool samples and samples of the small intestine taken during a colonoscopy to understand how tirzepatide helps heal the intestine.
Depemokimab is being developed as a treatment for individuals with moderate to severe COPD. The aim of this study is to assess the efficacy and safety of depemokimab as an add-on medicine in participants with uncontrolled moderate to severe COPD with type 2 inflammation.
This study will investigate the association between clonal hematopoiesis and other conditions. Clonal hematopoiesis (CH) refers to the mutations in a person's stem cells which commonly affect people as they get older. These mutations have notably been linked to increased risk of certain cancers as well as increased risk of heart disease.
This is a multi-center, hospital based, cross-sectional study based on data from patient medical records, including laboratory results. The study will include adult patients with chronic (\> 1 year duration) primary Immune Thrombocytopenia (ITP) only. Patients will be identified based on a laboratory confirmed diagnosis of ITP in the medical records, where there is also a physician-confirmed diagnosis of primary ITP. If patients consent to take part in the study, a routine clinical visit will also serve as the study visit. All study participants will have a routine blood test as part of their standard clinical care at the study visit, and this same procedure will be used to collect supplementary blood samples to assess a variety of biomarkers. Data will be collected using a combination of chart review, clinical outcome assessment administration, and laboratory results through blood tests.
Psoriasis is a chronic inflammatory disease that affects the skin and joints in 2-3 % of people in the United States. This inflammation of the skin, joints, and blood vessels in patients with psoriasis has been measured by older PET Scan technology but with limitations. With the new EXPLORER PET scanner technology, the investigators are testing to see if the EXPLORER is better than previous PET scanners and improve our ability to assess inflammation in patients. Also, it is known that the typical Western Diet - high in saturated fats, added sugars, and low in fiber - contributes to obesity and inflammation worldwide. There is evidence in animals that these signs of inflammation are reversible within 4 weeks when changed to a more balanced diet. Thus, this study aims to assess whether there are detectable decreases in inflammation of the skin and body of psoriasis patients who usually eat a Western Diet on an EXPLORER PET scan following 6 weeks of a more balanced diet.
The purpose of this study is to compare the efficacy and safety of albuterol/budesonide to albuterol in changes in airway inflammation, asthma symptoms, and rescue therapy utilization in adults with mild asthma. Study details include: * The study duration will be up to 15 weeks. * The treatment duration will be 12 weeks. * The visit frequency will be once every 4 weeks, with 3 clinic visits and 2 video calls in total.
Background: Diseases related to the immune system, blood clots, and blood vessels can affect every part of the body. These diseases are now known to be interrelated: People who have strokes, blood clots in their legs, or autoimmune disease, for example, are at greater risk of complications in the heart, brain, and other organs. Researchers want to learn more about how these diseases start, how they change over time, and how they affect different organs. Objective: To learn more about how inflammation and diseases of the blood vessels start and how they change over time. Eligibility: People aged 5 years and older with a disease related to blood clots, the immune system, or blood vessels. Healthy relatives of people with these diseases and unrelated healthy volunteers are also needed. Design: Participants will have a baseline visit: They will provide a medical history, physical exam and blood test. All other tests and procedures are optional; these may be spread over more than 1 day: Tests of heart and lung function. Fill in a family tree form. Imaging scans Treadmill or bike stress tests and a 6-minute walk test. Tests of blood pressure and the flow of blood through vessels. Photos of the face and body. Eye exams, with photos taken of the retina. Saliva and urine samples. Biopsies (tissues samples) of the skin and fat. Tests of thinking and mental function. Evaluations by other medical specialists. Participants may opt to return for repeat testing for up to 90 months (7.5 years). Some visits may be done by telehealth.
This study will track immune responsiveness to conjugate pneumococcal vaccines over time to help determine how long protection from this vaccine lasts in individuals with chronic medical conditions (in this study - HIV) and with age.
This phase II trial evaluates how a virtually supervised exercise intervention in combination with group counseling affects inflammation and the bacterial composition (microbiome) of the gut in smokers who are at high risk for lung cancer. Physical exercise has been shown to reduce lung cancer development and to have beneficial effects on the gut microbiome and inflammation. Group counseling may promote adherence to the exercise intervention by empowering participants to exert greater control over their behavior and environment. This clinical trial may help researchers understand how exercise impacts inflammation and the microbiome in people at risk for lung cancer and whether or not exercise with counseling can improve health outcomes in high-risk individuals.
