Filter by:Radiological examinations that require the administration of iodinated contrasts (IC) for diagnostic and therapeutic purposes are essential in current clinical practice, and their use in interventional procedures has been progressively increasing. IC can cause kidney damage, so there is caution in their use in at-risk populations. This fact may limit its diagnostic use, with data on underutilization of interventional techniques in patients with renal insufficiency, which worsen their prognosis. In addition, once the use of IC contrasts is decided, preventive measures, such as hyperhydration,are used and can have potential side effects, especially in patients at risk of heart failure (acute coronary syndrome, low left ventricular ejection fraction). New biomarkers of kidney damage have recently been developed, based on the detection of molecules expressed by the kidney in situations of early damage. The quantitative determination of cell cycle arrest proteins (Tissue Inhibitor of metalloproteinase 2 (TIMP2) and Insulin-Like Growth Factor Binding Protein -7 (IGFBP7)) can be predictive of the development of moderate to severe contrast-associated acute kidney injury. Urinary determination of [TIMP-2] x [IGFBP7] in patients with ACS (acute coronary syndromes) before cardiac catheterization would allow early identification of those patients vulnerable to IC-induced toxicity and adjustment of preventive measures.
Patients aged 18-89 with stable CAD and comorbidities receiving optimal medical treatment requiring PCI with iodinated contrast media. The aim of the study is to assess the prevalence of contrast-induced AKI in 2012-2013 and 2017 cohorts and to evaluate the potential risk factors of CI-AKI to better guide the prevention in patients of higher risk.
Currently, contrast-induced kidney injury cannot be diagnosed on the day of cardiac catheterization. Recently, proenkephalin (penKid) was introduced as a new glomerular filtration marker. The aim of this study is to investigate whether the change in penKid level allows for early detection of affected patients.
This study is designed to compare the bioavailability of the test Product(CE-Iohexol Injection) and the reference product Iohexol Injection (Omnipaque™) following intravenous injection in normal healthy volunteers. The secondary objective is to assess the safety and tolerability of the treatments administered. Captisol® is present to improve stability and to potentially reduce the risk of contrast-induced acute kidney injury(CI-AKI) associated with iohexol administration.
This prospective study is intended to evaluate if carvedilol has any potential protective effect over atorvastatin on the development of contrast-induced nephropathy (CIN) following cardiac catheterization in patients with moderate to high risk for CIN.
This study evaluates the safety of iodinated contrast medium administered to liver transplant candidates with decreased renal function undergoing coronary CT angiography. Incidence of post-contrast acute kidney injury in liver transplant candidates with decreased renal function and normal renal function will be compared.
A randomized, placebo-controlled, double-blind clinical trial of effect of allopurinol or febuxostat to prevent contrast induced acute kidney injury (CI-AKI)
In a double-blinded randomized clinical trial, all patients undergoing coronary artery catheterization who will met our criteria, will be enrolled into three groups to receive either, vitamin e, n-acetylcysteine, or placebo. The aim of study will be to compare the superiority of vitamin e over n-acetylcysteine for the prevention of contrast-induced acute kidney injury (CIAKI).
A large number of patients with symptomatic ischaemic heart disease undergo coronary artery bypass grafting (CABG) to alleviate their symptoms and improve prognosis. Given the progressive nature of coronary disease, bypass grafts can narrow or block over time, leading to chest pain and the need for further invasive coronary angiography. Invasive coronary procedures in patients with bypass grafts can be more complicated due to the variation in bypass graft ostia. This can lead to longer procedure times, with higher doses of contrast and radiation and more discomfort for the patient. The aim of this study is to see if the use of computed tomography cardiac angiography (CTCA) in patients with previous bypass grafts prior to invasive coronary angiography will help make their procedure safer and quicker.
The use of coronary intervention has increased over the last decade. Contrast induced nephropathy (CIN) that develops as a result of procedures using intravenous or intra arterial contrast enhancement, or other diagnostic procedures, has been reported to be the third leading cause of acute renal failure in hospitalized patients. It has been hypothesized that this occurs as a result of direct toxicity, oxidative stress, and ischemic injury. Numerous studies have evaluated the incidence of CIN in patients undergoing angiography. There are limited studies in the acute care setting. Therefore, a tool that could identify early risk factors for CIN would be valuable for patient care. Metabolomic profiling is the identification of small molecule metabolites that are altered in response to injury. We hypothetize that urine metabolomic profiles may differ in patients before and after contrast administration coronary intervention.We hypothesized that metabolomic profiles will differ between those patients who develop CIN and those who do not after contrast administration. In addition we believe that metabolomics profiles prior to angiography may identify subjects who will go on to develop CIN and are therefore at higher risk.
