Active clinical trials for "Inflammation"

This study is a proof o concept aiming to determine the efficacy of Puressentiel nasal protective spray (PNPS) in patients with allergic rhinitis. Cross over study, with a nasal provocative test (NPT) in patients with allergic rhinitis sensitized to grass pollen. A day 0 (first NPT) the following outcomes are recorded: allergic Rhinitis control test (ARCT) and Inspiratory nasal peak flow (INPF) before and 30 min after the NPT. Nasal lavage is performed 30 min after the NPT and 3 cytokines (IL4, IL5 and IL13 are measured by ELISA. An other NPT is performed at day 30 and the same outcomes measured. 30 min before NPT 2 nasal sprays of PNPS are administered in each nostril in a randomized manner and cross over, the patient being is own control. The primary outcomes ins the IL4, IL5 and IL13 concentrations in the nasal lavage. ARCT and INPF are the secondary outcomes.

Background: Uveitis refers to a large group of inflammatory diseases in the eye. The inflammation can be caused by many factors, such as trauma, medicine, or infection. It can also be caused by systemic diseases. Uveitis and ocular inflammation can cause vision loss. Both children and adults can have uveitis. Standard treatment is to suppress the immune system. But this can result in high costs as well as bad side effects. Researchers want to look at data from NEI studies. They want to learn more about how uveitis progresses and responds to treatment. Objective: To find biomarkers to better understand uveitic diseases, assess disease severity, and create outcome measures of response to treatment and disease activity. Eligibility: People ages 4 and older from certain NEI studies who have uveitis or ocular inflammation, and healthy volunteers Design: Data will be taken from NEI studies from January 1, 2000, to December 31, 2025. Data will only be collected for participants who agreed to let their data be used for future research. No new tests will be done on any samples. Laboratory results and images will be used. Medical chart data, such as symptoms, medicine history, and treatment course, will be used. Personal data, such as name, medical record number, and date of birth, will be used. COVID-19 has been reported to cause eye changes. Exam findings of participants who had COVID-19 will be reviewed as well. Machine learning will be used to study the data. This study will take place at the NIH Clinical Center. All data will be securely stored.

The relationship between the immune system and the myocardium after myocardial ischemia is an evolving field of research. Crosstalk occurs between macrophages and cardiac myocytes to promote cardio-protection and resolution of inflammation after myocardial ischemia and reperfusion injury (MI/R injury). Myeloid-epithelial-reproductive tyrosine kinase (MerTK), a member of the TAM family of tyrosine kinase receptors (Tyro-Axl-MerTK), is a macrophage receptor that mediates efferocytosis, anti-inflammatory signaling, and resolution of inflammation. After MI/R injury, intact MerTK is necessary for the phagocytosis of dead cardiac myocytes and to promote anti-inflammatory signaling. Proteolytic cleavage of MerTK to its inactive form, soluble MER, restricts the capacity of macrophages to phagocytize dead cardiac myocytes and impairs MerTK-dependent anti-inflammatory signaling resulting in suppressive effects on cardiac remodeling and function. The Thorp lab at Northwestern University has previously measured soluble MER levels in both adult mice and humans and found that soluble MER concentrations increase after MI/R injury. In adult MI patients, soluble MER was measured post coronary artery reperfusion and was found to be increased (average 3200 pg/mL compared to 1700 pg/mL) compared to controls with stable cardiovascular disease. Based on murine data, the lab further postulated that reperfusion injury may directly interfere with MerTK-dependent cardiac repair as reactive oxygen species formed during reperfusion injury induce proteolytic cleavage of MerTK to soluble MER. Myocardial infarctions are rare events in pediatric patients. However, pediatric hearts are exposed to periods of hypoperfusion, ischemia, and inflammation during times of stress such as cardiac bypass and critical illness, and it is unknown how soluble MER levels change in response to these events. Thus, I was interested in investigating how soluble MER levels change after MI/R injury induced by cardiac bypass as well as in the utility of soluble MER as a biomarker of cardiac inflammation and injury in pediatric patients.

Patients will be admitted in the intensive care unit after major abdominal surgery. All patients will receive 100 mg of tramadol intravenously every 6 hours. Pain will be assessed before and half an hour after tramadol administration by verbal Numeric Rating Scale.

Investigators aimed to measure the serum levels of adropin, salusin-α, netrin-1, and nesfatin-1, anti-inflammatory effects of which have been demonstrated previously, in endometriosis patients and to find out any association of them with insulin resistance.

In this investigation the investigators utilized NAC supplementation to boost GSH availability during an one-week-microcycle consisting of three soccer games, in order to test the hypotheses that: i) antioxidant supplementation may enhance the recovery of performance and physiological stress variables following multiple match-plays and ii) redox status perturbations are critical in regulating the inflammatory response and repair in skeletal muscle, following repetitive exercise-induced muscle injuries.

Randomized controlled trial of acute use of electronic cigarette or tobacco cigarette on parameters of ventricular repolarization and inflammation/oxidative stress.

Inflammation plays an important role in the pathogenesis of peritoneal carcinosis. Patients with elevated levels of different inflammation cytokines show a worse prognosis at the time of diagnosis. In women, ovarian and colon cancer are the main causes of peritoneal carcinosis and a comparison of these two different types of peritoneal invasion have not been conducted yet. We found interesting studying the role of immune response, in particular tumour-associated antigens (TAA) that modulate the metastatic process. We will investigate also mitochondrial defects, such as mutations in mt-DNA, potentially involved in carcinogenesis.

The aim of this study is to address questions regarding the link among hepcidin, hematological iron markers, inflammation and hepatitis C in HD patients. In attempt to address this issue, we planned to measure serum levels of hepcidin prohormone (pro-hepcidin), inflammatory and iron parameters.

About 32 healthy subjects are subjected to 4 weeks of exercise, 4 weeks of washout and 4 weeks of sedentary life style, randomization decides whether they start with exercise or with being "couch potatoes". All participants are also randomized to also consume 150 g of blueberries on exercise days or not. The exercise is constituted of 5 km running 5 days a week during the 4 week period. The exercise period and the "couch" period are started and ended with a 5 km run at maximal speed and the fasting blood samples for cardiovascular risk factors are measured before and after this run, ie 8 times in total.
