Active clinical trials for "Inflammation"

It is the central hypothesis of the investigators study that HIV disease is a pro-inflammatory condition, and that years of inflammation result in premature "aging' of the immune system ("immunosenescence"). Just as these changes are thought be causally associated with heart disease in the very old,the investigators postulate that these changes will be associated with early heart disease in the untreated and perhaps treated HIV disease. To address this hypothesis, the investigators will measure immunosenescence in a large cohort of patients who span the entire disease process.

People with diabetes are at increased risk for atherosclerosis and have high CVD morbidity and mortality rates. Tools for detecting and quantifying atherosclerotic pro/regression in people with diabetes and other CVD risk factors lack sensitivity and specificity for molecular level events that occur during the early stages of atherogenesis. Inflammatory macrophage infiltration in the vessel endothelium is an early, molecular level proatherogenic event. Activated macrophages consume glucose at a high rate. Novel in vivo radiotracer PET/CT techniques have been developed to detect, image and quantify molecular level events like macrophage inflammation and glucose utilization (18FDG) in human vessels. We propose to develop and test this novel technique in the Center for Clinical Imaging Research (CCIR) at WUMS. We propose that HIV-infected people with significant CVD risk profiles are a suitable, unique human model for testing these novel imaging techniques. HIV-infected people taking anti-HIV medications develop insulin resistance, T2DM, dyslipidemia, central adiposity, and hypertension. HIV replicates in macrophages and represents a chronic proinflammatory condition. Recent data indicate that HIV+ CVD risk have greater risk for atherosclerosis and MI than HIV-negative people. To test feasibility, we hypothesize that: a.18FDG-PET/CT imaging will detect more macrophage glucose uptake and inflammation in the carotid and aorta arteries of HIV-infected people with CVD risk than in HIV-negative controls; b. radiotracer PET/CT measures of proatherogenic processes will correlate with carotid intima media thickness; a standard measure of carotid atherosclerotic burden. We propose to obtain pilot data that shows feasibility for a novel analytical approach that will expand capabilities for researchers interested in studying the links between diabetes, inflammation, and CVD in humans.

Role of CD7 in skin inflammation and psoriasis

The purpose of this study is to determine if the metabolic syndrome is a risk factor for cognitive decline and if this association is modified by inflammation.

To determine inflammation markers over time in cardiovascular disease. To test the hypothesis that measures of coagulation and fibrinolysis correlate with the incidence of coronary heart disease (CHD) and other thrombosis related disorders, and to help identify those individuals at greatest risk, using the Cardiovascular Health Study (CHS) and Honolulu Heart Program (HHP) populations. These two genetically distinct populations had different event rates for CHD, and offered a unique opportunity to test associations that were uncovered by comparing results across populations.

The investigators will develop a radiomics signature for immune checkpoint-induced pneumonitis in 40 patients with a pulmonary event under anti-PD1 or anti-PD-L1 (cases) and 40 patients without a pulmonary event under anti-PD1 or anti-PD-L1 (controls). On the basis of the case-control study of patients treated with anti-PD1 or anti-PD-L1, they will further optimise the model using reinforcement machine learning. The model will then be validated in 300 prospective patients.

TIPIC syndrome (previously called carotidynia) is a rare entity of unknown cause, where the patient has a temporary cervical pain associated with a suggestive inflammation around the carotid artery. Usually considered as a unique and benign episode, some patients have recurrences and the follow-up is usually short. In this study the investigators aim to evaluate patients who presented a TIPIC episode at least 3 months before, clinically and with a cervical doppler ultrasound

Monitoring of inflammatory substances (such as interleukins, CRP, albumine), and markers of organ dysfunction (such as creatinine, proenkephaline, amylase, troponine, IFABP and lactate) during elective liver resection. The study also includes monitoring of hemodynamic parameters, blood loss and postoperative complications. Results are to be used för power calculation for future trials.

Patients with acute myocarditis (AM) usually experience spontaneous healing, but a considerable percentage of them evolve towards chronic long-term cardiac impairment. The evolution towards dilated cardiomyopathy (DCM) occurs in a subtle manner, frequently after an initial recover that mimics complete healing. Differences in the course of the disease may reflect the course of underlying myocardial inflammation related to viral clearance or persistence and to the following autoimmune response. Cardiac magnetic resonance (CMR) mapping parameters have been developed for the quantification of edema and necrosis, showing high diagnostic accuracy. No mapping parameter has been developed for the assessment of the third Lake Louise criteria, namely the hyperemia, and, furthermore, their prognostic role is not completely understood. The study hypothesis is that the early-enhanced T1 mapping parameter may have great diagnostic accuracy for myocarditis, and that a short-term monitoring with a complete CMR protocol at 2 month after symptoms onset may identify the subgroup of patients at high risk of progression towards DCM. The results of this study will help to significantly improve diagnostic performances of CMR and may help to manage patients with AM.

Early enteral nutrition(EEN) is an important treatment for critical ill patients and attenuate systemic inflammation, but the mechanisms are not clear. Thus the investigator conducted this study to observe if EEN affects systemic inflammation though regulation of blood acetylcholine
