This phase II/III trial compares the side effects and activity of oral azacitidine in combination with the standard drug therapy (reduced dose rituximab-cyclophosphamide, doxorubicin, vincristine, and prednisone \[R-miniCHOP\]) versus R-miniCHOP alone in treating patients 75 years or older with newly diagnosed diffuse large B cell lymphoma. R-miniCHOP includes a monoclonal antibody (a type of protein), called rituximab, which attaches to the lymphoma cells and may help the immune system kill these cells. R-miniCHOP also includes prednisone which is an anti-inflammatory medication and a combination of 3 chemotherapy drugs, cyclophosphamide, doxorubicin, and vincristine. These 3 chemotherapy drugs, as well as oral azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Combining oral azacitidine with R-miniCHOP may shrink the cancer or extend the time without disease symptoms coming back or extend patient's survival when compared to R-miniCHOP alone.

Background: Respiratory diseases affect more than 1 billion people worldwide. They are a growing public health concern. The lungs are constantly exposed to environmental factors such as dust, fumes, microbes, and pollutants. But much is still not known about how these pollutants lead to respiratory illnesses. Researchers want to collect samples from lungs and blood to see how genetics and environmental pollutants affect cellular responses or functioning. Objectives: To study how cytochrome P450 epoxygenase pathway enzymes affect macrophage function in the lungs and inflammatory responses. Eligibility: Adults ages 18 65 who can have a bronchoscopy. Design: All study visits will take place at the NIEHS Clinical Research Unit in Research Triangle Park, NC. At study visit 1, participants will be screened with medical history and physical exam. They will have blood and urine tests. They will take tests that measure their lung function. They will answer questionnaires. Before the visit, they will be given a list of medicines they cannot take. They also must not have caffeine on the day of their visit. The visit will last about 3 hours. At study visit 2, participants will give blood samples. They will undergo bronchoscopy. For this, they will get an intravenous line in a vein to get sedatives. Their airways will be numbed. Cells will be collected from their lungs. They will fast for 8 hours before the visit. They must have someone else drive them home from the visit. The visit will last about 3-4 hours. Participants will get a follow-up phone call about 1 day after study visit 2. ...
NCT07011394
Asthma is a common inflammatory respiratory disease affecting 11% of Canadians, but its diagnosis remains challenging, leading to delays in treatment or overtreatment. Spirometry with a reversibility test and bronchial provocation testing (BPT), considered the gold standard, are the reference diagnostic methods. However, access to BPT is limited as it is performed in hospital settings. Type 2 inflammation biomarkers, the fractional exhaled nitric oxide (FeNO) and blood eosinophils (EOS), represent a potential alternative. In addition to their prognostic and theragnostic value, these markers predict a good response to inhaled corticosteroids in individuals aged ≥ 6 years with asthma. However, their use remains restricted to pulmonologists in specialized clinics and is not recommended as a diagnostic tool in Quebec. Despite studies demonstrating their diagnostic value in specialized settings, these tests remain underexplored in primary care and insufficiently studied in children under 12 years. The objective of ou study is to evaluate the relevance and performance of FeNO and blood eosinophils in the diagnosis of asthma in children referred in primary care with non-diagnostic spirometry.
NCT07571473
This randomized controlled trial evaluates whether intraoperative guidance using the CoreSys monitor reduces the surgical stress response in patients undergoing elective open abdominal hysterectomy. Surgical stress involves complex hemodynamic, endocrine, and inflammatory responses that may negatively impact postoperative recovery. Patients will be randomized to either anesthesia guided by conventional clinical and hemodynamic parameters or anesthesia additionally guided by CoreSys-derived indices of consciousness, nociception, and stress activity. The primary objective is to assess whether CoreSys-guided anesthesia attenuates stress biomarkers, including interleukin-6 (IL-6), cortisol and glycemia.
NCT04626505
The purpose of this research study is to compare the safety and effectiveness of 2 different doses of a study drug called ziltivekimab to placebo (an inactive substance) in reducing inflammation and improving some of the bad effects of inflammation on heart disease. Participants will be randomly (by chance) assigned to receive either ziltivekimab or placebo. The chance that participants will be assigned into one of the three study arms of ziltivekimab (either 15 mg or 30 mg) or placebo is the same (approximately 33%). This is a double-blind study, which means neither participants nor the study doctor will know which group the participants are in. In case of an emergency, however, the study doctor can get this information. The study drug will be injected under the skin once every 4 weeks. In this study participants will receive 3 injections of study drug. The total study duration for each participant will be approximately 6 months.
NCT05190978
Surgical mesh products, particularly acellular dermal matrices (ADM), are now used by the majority of plastic surgeons to assist with the nearly 100,000 prosthetic breast reconstruction procedures in the United States, despite never being approved by Food and Drug Administration (FDA) for this indication. As surgeons transition to placing breast implants above the chest muscle (pre-pectoral), there has been an increasing reliance on these often expensive mesh products without robust evidence to understand their risks and benefits. Our pilot study is a randomized multi-center trial to evaluate surgical mesh assistance in pre-pectoral tissue expander to breast implant reconstruction to address vital questions for women's public health.
NCT00001351
This study will investigate inflammatory diseases and disorders. Inflammation is the body s immune response to many things, including infections and other acute or chronic irritants. It may also be a sign of abnormal immune function. This study will allow evaluation and long-term follow-up of such disorders to: * Establish and maintain a group of patients that may be eligible for other NIAID protocols. * Provide clinical training and experience for NIAID fellows. * Provide a mechanism for NIAID staff to maintain their clinical skills. * Serve as a starting point for new investigations of syndromes not currently under study. Patients between 1 and 80 years of age with acute or chronic inflammation, including but not limited to viral, fungal or bacterial infections, or abnormal immune responses may be eligible for this study. Immediate family members of patients may also be enrolled for preliminary examination to see if they are affected in any way that may warrant further investigation. All patients and family members will have a history, physical examination and laboratory tests. Depending on the results, family members may require additional tests. Patients will have additional diagnostic tests indicated for their specific disease, according to accepted medical standards. These may include routine blood and urine tests, X-rays or other imaging studies, body fluid or tissue cultures, skin tests for allergic or immune responses, and others as needed. Treatments will include only medications approved by the Food and Drug Administration according to accepted dose schedules and delivery methods. Patients may be requested to donate extra blood for research studies. No more than 450 cc (30 tablespoons) will be drawn from adults within a 6-week period, and no more that 7 cc (1/2 tablespoon) from children under 18 years of age in the same time period. ...

Type 2 Diabetes Mellitus (T2DM) is a very common disease in Mexico, and its long-term complications affect years of healthy life and a high cost in treatmenty. T2DM is a chronic disease associated to inflammation. We aim to establish if Vitamin D may help decrease this inflammation and improve the condition in adults with T2DM. Patients included in the study will have to take 1 pill/day of vitamin D for six months. The investigators will measure weight, height, waist and hip circumference, systolic and dyastolic blood pressure; obtain dietary and clinical information, as well as a 10mL blood sample from the arm, for laboratory analyses, finger-prick blood sample for glucose at the beginning and end of the study; ´plus a finger-prick blood samplo for the initial vitamin D status. The study is completely free for the participants and they may withdraw their consent at any time without any consequences. Participants will have to attend the clinic at the beginning and every two months until the end, to receive their supplement (total 4 appointments). They will receive a phone call once a week to remind you to take your pills. They will be handed your results at the end of the study.
NCT00001373
This study is designed to explore the genetics and pathophysiology of diseases presenting with intermittent fever, including familial Mediterranean fever, TRAPS, hyper-IgD syndrome, and related diseases. The following individuals may be eligible for this natural history study: 1) patients with known or suspected familial Mediterranean fever, TRAPS, hyper-IgD syndrome or related disorders; 2) relatives of these patients; 3) healthy, normal volunteers 7 years of age or older. Patients will undergo a medical and family history, physical examination, blood and urine tests. Additional tests and procedures may include the following: 1. X-rays 2. Consultations with specialists 3. DNA sample collection (blood or saliva sample) for genetic studies. These might include studies of specific genes, or more complete sequencing of the genome. 4. Additional blood samples a maximum of 1 pint (450 ml) during a 6-week period for studies of white cell adhesion (stickiness) 5. Leukapheresis for collecting larger amounts of white cells for study. For this procedure, whole blood is collected through a needle in an arm vein. The blood flows through a machine that separates it into its components. The white cells are removed and the rest of the blood is returned to the body through another needle in the other arm. Patients may be followed approximately every 6 months to monitor symptoms, adjust medicine dosages, and undergo routine blood and urine tests. They will receive genetic counseling by the study team on the risk of having affected children and be advised of treatment options. Participating relatives will undergo a medical and family history, possibly with a review of medical records, physical examination, blood and urine tests. Additional procedures may include a 24-hour urine collection, X-rays, and consultations with medical specialists. A DNA sample (blood or saliva) will also be collected for genetic studies. Additional blood samples of no more than 550 mL during an 8-week period may be requested for studies of white cell adhesion (stickiness). Relatives who have familial Mediterranean fever, TRAPS, or hyper-IgD syndrome will receive the same follow-up and counseling as described for patients above. Normal volunteers and patients with gout will have a brief health interview and check of vital signs (blood pressure and pulse) and will provide a blood sample (up to 90 ml, or 6 tablespoons). Additional blood samples of no more than 1 pint over a 6-week period may be requested in the future.
NCT07543666
A sedentary lifestyle and obesity are associated with chronic low-grade inflammation and an elevated risk of cardiovascular disease (CVD). This study aims to systematically characterize and compare the effects of three distinct exercise modalities - moderate-intensity, vigorous-intensity, and short-duration maximal exercise - each differing in duration and intensity, on systemic inflammation and immune function. The study investigates the potential of exercise as an effective anti-inflammatory intervention for the prevention of CVD.

Major depressive disorder (MDD) affects an estimated 350 million people worldwide and is a leading contributor to global disease burden. Commonly used monoamine reuptake-inhibiting treatments for depression are suboptimal, resulting in only 30% of patients achieving remission. This may be because monoamine dysfunction is not the primary pathophysiology in all MDD patients. One avenue for the development of novel MDD treatments is through anti-inflammatory drugs; MDD is linked to a pro-inflammatory phenotype characterized by microglial activation, leading to the release of pro-inflammatory cytokines and upregulation of cellular markers including cyclooxygenase-2 (COX-2) and translocator protein (TSPO; a protein located on the outer membrane of microglia). Relevant to this proposal, TSPO can serve as an in vivo marker of neuroinflammation using the newly developed positron emission tomography (PET) tracer for TSPO, \[18F\]FEPPA. In support of this, a recent \[18F\]FEPPA PET study found that MDD patients in a current major depressive episode (MDE) had significantly higher TSPO binding in the prefrontal cortex (PFC), anterior cingulate cortex (ACC) and insula, relative to healthy controls. The prefrontal cortex and ACC are both implicated in mood regulation whereas the insula is involved in interoceptive signaling, which is known to be abnormal in MDD. Celecoxib, a selective COX-2 nonsteroidal anti-inflammatory drug (NSAID), is a promising new treatment for neuroinflammation in MDD. Clinical studies have observed that, in a subset of depressed patients, celecoxib treatment reduced depression severity as assessed by the Hamilton Depression Rating Scale (HDRS). While these findings demonstrate that celecoxib reduces symptom severity, PET imaging technology is critical for understanding how celecoxib affects the underlying pathophysiology of depression. Here, the team will investigate neuroinflammation as an underlying pathology in depression and test whether neuroinflammation is reduced by celecoxib in MDD patients. Specifically, in the proposed pilot study, MDD patients in a current MDE will receive \[18F\]FEPPA PET scans prior to and following 8 weeks of treatment with 400mg/day of celecoxib, with HDRS scores obtained at each time point. The investigators hypothesize that following celecoxib treatment, patients will show a significant reduction in neuroinflammation in the PFC, ACC and insula, which will correlate positively with the reduction in depressive symptoms, as measured by the HDRS. The proposed study will use novel imaging technology, \[18F\]FEPPA PET, to measure the effects of celecoxib on neuroinflammation in MDD patients. Our results will help to 1) identify neuroinflammation as an underlying pathology in MDD and 2) test whether reduction of inflammation is the mechanism of action of celecoxib. As such, the results of this study will aid in the development of targeted clinical treatments to improve remission rates in MDD patients.
NCT07550023
This study will investigate how adding a specific type of dietary fat to daily meals for two weeks affects the gut bacteria and their activity. Participants will be randomly assigned to consume one of four types of fat: butter, coconut oil, olive oil, or sunflower oil (60 mL each day for 2 weeks). Stool and blood samples (after an overnight fast) will be collected at 3 time points during the study (Days 1, 7, and 22). These samples will be used to measure metabolites produced by gut bacteria, the types of bacteria present in the gut, blood lipids, and inflammatory markers. The study, based on previous in vitro findings, aims to understand whether different types of fats (based on their structure and level of saturation) have different effects on gut bacteria and their activity in healthy subjects.

Background: \- Cardiometabolic diseases are medical disorders that can occur together and affect the heart. They increase the risk of developing heart disease and diabetes. One disorder, psoriasis, is an inflammation that mostly affects the skin but can affect the entire body. Another disorder, atherosclerosis, is a process in which cholesterol is gradually deposited on the wall of arteries. This causes arteries to harden and become less flexible. Many cells that cause psoriasis also cause atherosclerosis. Researchers want to look at the relationship between cardiometabolic diseases and psoriasis. Objectives: \- To study the relationship between psoriasis and cardiometabolic diseases. Eligibility: \- Individuals at least 18 years of age who have psoriasis. Design: * Participants will be screened with a physical exam and medical history. * Participants will have up to seven outpatient visits over the 4 years. The first visit will be a screening visit. Visits 2 will be12 months after visit 1. Visits 3, 4, and 5, will be scheduled yearly for the next 3 years. If participants have a psoriasis flare with more severe symptoms, they may have an extra visit. Those who leave the study early will have a final visit with the full series of tests. * At visits 1, 2,and 5, and any flare visits, participants will have a physical exam and medical history. They will provide blood and urine samples, as well as optional tissue biopsies. They will also have heart function tests. Imaging studies, as well as optional photographs of affected areas, will be performed. These tests will also be performed at the final visit. * At visits 3 and 4, participants will have a physical exam and medical history. They will also provide blood and urine samples, and have heart function tests.
NCT07547774
Sleep quality is a key physiological factor influencing immune function, inflammatory response, and pain perception. This prospective observational study aims to evaluate whether preoperative sleep quality predicts postoperative inflammation, pain severity, and analgesic consumption in patients undergoing elective breast cancer surgery. Preoperative sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI). Systemic inflammatory response will be evaluated using the Systemic Immune-Inflammation Index (SII), calculated from routine hematological parameters. Postoperative pain will be assessed using the Visual Analog Scale (VAS), and analgesic consumption will be recorded within the first 24 hours. The study aims to determine whether poor sleep quality is associated with increased inflammatory response, higher pain scores, and greater analgesic requirement.
NCT06101784
Avenanthramides (AVA) are di-phenolic compounds found only in oats and are of interest due to suggested bioactivities, including antioxidant and anti-inflammatory effects in vitro and in vivo. Published data suggests that polyphenols can work as modifiers of signal transduction pathways to elicit their beneficial effects. These natural compounds express anti-inflammatory activity by modulation of pro-inflammatory gene expression such as cyclo-oxygenase, lipoxygenase, nitric oxide synthases and several pivotal cytokines, mainly by acting through nuclear factor-kappa B and mitogen-activated protein kinase signaling. The biomarkers of inflammation in blood, i.e., pro-inflammatory cytokines, chemokines, as well as other inflammatory markers (i.e., high sensitivity C-reactive protein) are of particular interest. Primary Objectives: * To assess the safety and tolerability of single ascending oral doses of avenanthramide in healthy subjects. * To assess the safety and tolerability of multiple ascending oral doses of avenanthramide in healthy subjects and subjects with elevated waist circumference and low-grade inflammation. Secondary Objectives: * To determine the pharmacokinetics of avenanthramide following single ascending oral doses in healthy subjects. * To compare the pharmacokinetics of avenanthramide following single oral dose in healthy subjects under fasting and fed conditions. * To determine the pharmacokinetics of avenanthramide following multiple ascending oral doses in healthy subjects. * To determine the pharmacokinetics of avenanthramide following multiple ascending oral doses in subjects with elevated waist circumference and low-grade inflammation.
NCT04888923
Background: Environmental exposures like pollution, diet, and stress can help cause human diseases, or make them worse. Researchers want to better understand how injury and inflammation are caused by these exposures. They want to collect biological and environmental samples and other data. They may use the samples to measure a range of factors, like hormones, toxins, and chemicals. This will help them improve their studies. Objective: To identify and understand how environmental exposures contribute to human disease. Eligibility: Healthy adults ages 18 and older Design: Participants will be screened with questions about their health history, demographics, and medicines they take. Participants may give blood, hair, stool, saliva, and/or urine samples. They may have a skin punch biopsy to collect skin cells. They may give fingernail or toenail clippings. They may give a sample of exhaled breath. Participants may give a sputum sample. They will inhale a saline mist and cough mucus into a cup. Participants may have their nasal passages brushed, scraped, or washed. Participants may give cheek cell samples. They will swish mouthwash and spit it into a cup. Participants who produce sperm may give samples. Participants may have bronchoscopy to collect fluid. A saline solution will be put into their lung and then suctioned out, washing areas of the lung. Participants may have a pelvic or transvaginal ultrasound. They may have lung function tests. Participants may collect household dust, urine, or stool at home. Participants will complete surveys about their health, diet, and exposures. Participation will last for one or more study visits. Participants may be contacted in the future to take part in other studies.

The purpose of this investigation is to evaluate how early biomarkers of infection and inflammation perform in identifying patients at risk for poor outcome in sepsis and septic shock.
NCT00776412
This study will collect information about markers of inflammation, blood clotting and blood vessel function in HIV-infected adults and healthy volunteers. Biomarkers are biological indicators that have been associated with disease. Certain markers of inflammation, blood clotting, and blood vessel function have been associated with risk of cardiovascular disease, stroke and death. One marker, called D-dimer, is a breakdown product of blood clots that has been associated with serious medical conditions, including deep vein thrombosis (formation of a blood clot in a vein deep in the body) and pulmonary embolism (blockage in the pulmonary artery that occurs when a blood clot from a vein breaks away, travels to the pulmonary artery and lodges there). High D-dimer levels have also been associated with cardiovascular disease and stroke risk. In a recent study of HIV-infected patients, higher D-dimer levels were strongly correlated with risk of death from any cause. The significance of changes in D-dimer and other biomarkers in HIV-infected adults is not well understood. This study will further explore D-dimer and other biomarkers to try to better understand the relationships between them and HIV infection. Healthy volunteers and HIV-infected adults 18 years of age or older may be eligible for this study. Two visits are involved, as follows: Visit 1 (screening visit to determine eligibility) * Medical history and physical examination. * Blood tests for HIV infection, blood counts, liver and kidney function. * Pregnancy test for women who can become pregnant. Visit 2 * Blood tests for hepatitis B and C * Blood tests for markers of inflammation and blood clotting. * Blood test for genetic changes that influence blood clotting. In some cases, visits 1 and 2 may be combined. Optional additional visits (up to 8 visits over 3 years) * Additional blood draws for investigation of specific clinical or laboratory findings may be requested.
NCT05021835
This study is conducted to see if ziltivekimab reduces the risk of having cardiovascular events (for example heart attack and stroke) in people with cardiovascular disease, chronic kidney disease and inflammation. Participants will either get ziltivekimab (active medicine) or placebo (a dummy medicine which has no effect on the body). This is known as the study medicine. Which treatment participants get is decided by chance. Participants chance of getting ziltivekimab or placebo is the same. Ziltivekimab is not yet approved in any country or region in the world. It is a new medicine doctors cannot prescribe. Participants will get the study medicine in a pre filled syringe. Participants will need to use the pre filled syringe to inject the study medicine into a skinfold once-monthly. The study is expected to last for up to 4 years. Participants will have up to 20 clinic visits. Participants will have blood and urine samples taken at most of the clinic visits. Participants will have their heart examined using sound waves (echocardiography) and electrodes (electrocardiogram). Women cannot take part if pregnant, breast-feeding or planning to get pregnant during the study period.
