Active clinical trials for "Reperfusion Injury"

Perla® is a Cold Preservation Solution, with purpose to wash out, preserve during transport liver and kidney grafts in optimal conditions from the donor to the recipient. The purpose of the PERTRIAL clinical investigation is to demonstrate the Performance and Safety of Perla® Cold Preservation solution.

Remote ischemic preconditioning(RIPC) is emerging as an promising therapeutic paradigm to combat the detrimental impact of ischemic and reperfusion injury. In liver transplantation, ischemic and reperfusion injury severely impacts the post-surgery liver function and patient outcome. This prospective, double blind, randomized clinical trial is aimed to test the protective effect of RIPC against hepatic ischemic and reperfusion injury in pediatric liver transplantation.

The application of tourniquet is indispensable for a bloodless surgical area in total knee arthroplasty surgery. The release of tourniquet produces reactive oxygen species which can cause injury and then ischemia-reperfusion injury emerge. Our aim in this study is to investigate effects of pregabalin, GABA analog drug, on the tourniquet induced ischemia-reperfusion injury.

The purpose of this study is to establish the effectiveness of the combined drug approach (anti-thrombin III, infliximab, apotransferrin, human recombinant erythropoietin beta, C1-inhibitor, glutathione, alfa-tocopherol, melatonin and epoprostenol)aimed to reduce ischemia-reperfusion injury during liver transplantation in eligible recipients.

The aims of this study are: assessment of ischemia injury of kidney retrieved from standard and expanded criteria deceased donor before transplantation assessment of efficacy of kidney ischemia injury decreasing assessment of influence of kidney ischemia injury decreasing on its function after transplantation For the purpose of this research one hundred kidney will be retrieved from deceased donors (standard and expanded criteria deceased donors) for transplantation. All kidneys before transplantation will be stored in machine perfusion in hypothermia with continuous flow - Organ Recovery Systems LifePort - each single kidney in self-contained perfusion system. For the kidney allograft assessment will be used measurements performed during machine perfusion in hypothermia: renal flow, resistance, lactate dehydrogenase, lactates and ischemia injury markers measured in the fourth hour of perfusion in perfusion fluid. For kidney ischemia injury assessment such markers will be measured: tumour necrosis factor (TNF alfa), interleukin 2 (IL-2), interleukin 6 (IL-6), high sensitivity C-reactive protein (hsCRP), platelet-derived growth factor (PDGF), cystatin C, kidney Injury Molecule (KIM-1), neutrophil Gelatinase-associated Lipocalin (NGAL), complement component C3, caspase 3. Every time from pair of retrieved kidneys each kidney will be randomise for one of the group: group 1) - 50 kidneys - examined group - "cured" with etanercept (ENBREL) in the first hour of perfusion by adding drug to perfusion fluid, group 2) - 50 kidneys - control group - without intervention. Ischemia injury markers will be measured in perfusion fluid by kidney two times (in the first and fourth hour of perfusion) for assessment of efficacy kidney ischemia injury decreasing. Results of measurements of kidney ischemia injury before transplantation, parameters during machine perfusion in hypothermia and donor parameters will be correlated with kidney allograft function post transplantation. Immediate, delayed and slow graft function, primary non-function, kidney function assessed by creatinine concentration and creatinine clearance at one day, seven days, two weeks, 1, 6 and 12 months post transplantation and kidney graft survival 6 and 12 months post transplantation will be analysed.

The use of volatile anesthetics in cardiac anesthesia is very common, because of their cardioprotective effects and their ability to ensure a sufficient depth of anesthesia. In line with the development of fast track concepts in cardiac anesthesia, volatile anesthetics are widely used to avoid a delayed recovery from cardiac surgery and anesthesia. Volatile anesthetics are delivered from calibrated vaporizers in the anesthesia machine or the cardiopulmonary bypass machine (during extracorporeal circulation). Isoflurane and Sevoflurane are the most commonly used volatile anesthetics in patients undergoing cardiopulmonary bypass (CPB). The vaporizer of the anesthetics is on the cardiopulmonary bypass machine and the volatile agent is blended with air and oxygen. Until now, the pharmacokinetics of halothane, enflurane, isoflurane and desflurane during CPB have been described. Sevoflurane might be of advantage because of additional myocardial protective effects during cardiac anesthesia and cardiopulmonary bypass. However, the pharmacokinetics of sevoflurane during CPB have not been investigated so far, although its being used at many hospitals. The investigators will conduct a randomized prospective study with either sevoflurane or isoflurane during cardiopulmonary bypass surgery. The study will help to answer the questions about the possible cardioprotective effects of the widely used volatile anesthetics and the hemodynamic stability during cardiopulmonary bypass. Knowing the pharmacokinetics of these drugs allows the anesthesiologist to titrate the volatile anesthetics more precise. The investigators hypothesizes that the maximal postoperative increase in troponin T will be smaller in the sevoflurane group than in the isoflurane group. The investigators hypothesizes that the total amount of noradrenaline needed during the entire period of cardiopulmonary bypass will be smaller in the sevoflurane group than in the isoflurane group. The investigators hypothesizes that kinetics of washin and washout at the CPB will be faster in the sevoflurane group than in the isoflurane group. The investigators hypothesizes that the time to extubation, respectively the length of stay in intensive care unit and hospital is shorter in the sevoflurane group than in the isoflurane group.

In the laboratory, the researchers will investigate whether the drug eplerenone improves contractile function after ischemia and reperfusion in heart tissue.

The EMBRACE-STEMI trial was a Phase 2a prospective, multicenter, multinational randomized, double-blind, placebo-controlled study designed to assess the safety, tolerability, and efficacy of IV administered elamipretide (also known as MTP-131, or Bendavia) on a background of standard-of-care therapy for reduction of reperfusion injury in patients with first time acute, anterior wall ST-segment elevation myocardial infarction (STEMI).

The purpose of this study is to determine the effect of MC-1 on the combined incidence of cardiovascular death and nonfatal myocardial infarction (MI) up to and including 30 days following coronary artery bypass graft (CABG) surgery compared with placebo.

The purpose of this study is to determine if oral atorvastatin administered just before percutaneous coronary angioplasty for acute myocardial infarction improves early and late heart function as compared to placebo.
