Abstract

Introduction Surgical-site infection (SSI) is the second most frequent cause of healthcare-associated infection worldwide and is associated with increased morbidity, mortality and healthcare costs. Cardiac surgery is clean surgery with low incidence of SSI, ranging from 2% to 5%, but with potentially severe consequences. Perioperative skin antisepsis with an alcohol-based antiseptic solution is recommended to prevent SSI, but the superiority of chlorhexidine (CHG)–alcohol over povidone iodine (PVI)–alcohol, the two most common alcohol-based antiseptic solutions used worldwide, is controversial. We aim to evaluate whether 2% CHG–70% isopropanol is more effective than 5% PVI–69% ethanol in reducing the incidence of reoperation after cardiac surgery. Methods and analysis The CLEAN 2 study is a multicentre, open-label, randomised, controlled clinical trial of 4100 patients undergoing cardiac surgery. Patients will be randomised in 1:1 ratio to receive either 2% CHG–70% isopropanol or 5% PVI–69% ethanol for perioperative skin preparation. The primary endpoint is the proportion of patients undergoing any re-sternotomy between day 0 and day 90 after initial surgery and/or any reoperation on saphenous vein/radial artery surgical site between day 0 and day 30 after initial surgery. Data will be analysed on the intention-to-treat principle. Ethics and dissemination This protocol has been approved by an independent ethics committee and will be carried out according to the principles of the Declaration of Helsinki and the Good Clinical Practice guidelines. The results of this study will be disseminated through presentation at scientific conferences and publication in peer-reviewed journals. Trial registration number EudraCT 2017-005169-33 and NCT03560193.

Abstract

Despite the fact that a significant fraction of kidney graft dysfunctions observed after transplantation is due to ischemia-reperfusion injuries, there is still no clear consensus regarding optimal kidney preservation strategy. This stems directly from the fact that as of yet, the mechanisms underlying ischemia-reperfusion injury are poorly defined, and the role of each preservation parameter is not clearly outlined. In the meantime, as donor demography changes, organ quality is decreasing which directly increases the rate of poor outcome. This situation has an impact on clinical guidelines and impedes their possible harmonization in the transplant community, which has to move towards changing organ preservation paradigms: new concepts must emerge and the definition of a new range of adapted preservation method is of paramount importance. This review presents existing barriers in transplantation (e.g., temperature adjustment and adequate protocol, interest for oxygen addition during preservation, and clear procedure for organ perfusion during machine preservation), discusses the development of novel strategies to overcome them, and exposes the importance of identifying reliable biomarkers to monitor graft quality and predict short and long-term outcomes. Finally, perspectives in therapeutic strategies will also be presented, such as those based on stem cells and their derivatives and innovative models on which they would need to be properly tested.

Abstract

International audience; The vascular network is a major target of ischemia-reperfusion, but has been poorly investigated in renal transplantation. The aim of this study was to characterize the remodeling of the renal vascular network that follows ischemia-reperfusion along with the most highly affected cortex section in a preclinical renal transplantation model. There were two experimental groups. The first was a grafted kidney group consisting of large white pigs for which the left kidney was harvested, cold flushed, preserved for 24 h in the University of Wisconsin’s preservation solution, and then auto-transplanted (n = 5); the right kidney was removed to mimic the situation of human kidney transplantation. The second group (uni-nephrectomized kidney group) consisted of animals that underwent only right nephrectomy, but not left renal transplantation (n = 5). Three months after autotransplantation, the kidneys were studied by X-ray microcomputed tomography. Vessel morphology and density and tortuosity of the network were analyzed using a 3D image analysis method. Cortical blood flow was determined by laser doppler analysis and renal function and tissue injury assessed by plasma creatinine levels and histological analysis. Renal ischemia-reperfusion led to decreased vascular segment volume associated with fewer vessels of less than 30 μm, particularly in the inner cortex:0.79 ± 0.54% in grafted kidneys vs. 7.06 ± 1.44% in uni-nephrectomized kidneys, p < 0.05. Vessels showed higher connectivity throughout the cortex (the arborescence factor of the whole cortex was less in grafted than uni-nephrectomized kidneys 0.90 ± 0.04 vs. 1.07 ± 0.05, p < 0.05, with an increase in the number of bifurcations). Furthermore, cortical blood flow decreased early in kidney grafts and remained low three months after auto-transplantation. The decrease in microvasculature correlated with a deterioration of renal function, proteinuria, and tubular dysfunction, and was associated with the development of fibrous tissue. This work provides new evidence concerning the impact of ischemia-reperfusion injuries on the spectrum of renal vascular diseases and could potentially guide future therapy to preserve microvessels in transplantation ischemia-reperfusion injury.

Abstract

International audience; Decreasing organ quality is prompting research toward new methods to alleviate ischemia reperfusion injury (IRI). Oxidative stress and nuclear factor kappa beta (NF‐κB) activation are well‐described elements of IRI. We added cyclodextrin‐complexed curcumin (CDC), a potent antioxidant and NF‐κB inhibitor, to University of Wisconsin (UW) solution (Belzer's Solution, Viaspan), one of the most effective clinically approved preservative solutions. The effects of CDC were evaluated on pig endothelial cells and in an autologous donation after circulatory death (DCD) kidney transplantation model in large white pigs. CDC allowed rapid and lasting uptake of curcumin into cells. In vitro, CDC decreased mitochondrial loss of function, improved viability and lowered endothelial activation. In vivo, CDC improved function recovery, lowered histological injury and doubled animal survival (83.3% vs. 41.7%). At 3 months, immunohistochemical staining for epithelial‐to‐mesenchymal transition (EMT) and fibrosis markers was intense in UW grafts while it remained limited in the UW + CDC group. Transcriptional analysis showed that CDC treatment protected against up‐regulation of several pathophysiological pathways leading to inflammation, EMT and fibrosis. Thus, use of CDC in a preclinical transplantation model with stringent IRI rescued kidney grafts from an unfavorable prognosis. As curcumin has proved well tolerated and nontoxic, this strategy shows promise for translation to the clinic

Abstract

Due to organ shortage, clinicians are prone to consider alternative type of organ donors among them donors deceased after circulatory death (DCD). However, especially using these organs which are more prone to graft dysfunction, there is a need to better understand mechanistic events ocuring during ischemia phase and leading to ischemia/reperfusion injuries (IRI). The aim of this study is to provide a dynamic transcriptomic analysis of preclinical porcine model kidneys subjected to ischemic stress mimicking DCD donor. We compared cortex and corticomedullary junction (CMJ) tissues from porcine kidneys submitted to 60 min warm ischemia (WI) followed by 0, 6 or 24 hours of cold storage in University of Wisconsin solution versus control non-ischemic kidneys (n = 5 per group). 29 cortex genes and 113 CMJ genes were significantly up or down-regulated after WI versus healthy kidneys, and up to 400 genes were regulated after WI followed by 6 or 24 hours of cold storage (p < 0.05). Functionnal enrichment analysis (home selected gene kinetic classification, Gene-ontology-biological processes and Gene-ontology-molecular-function) revealed relevant genes implication during WI and cold storage. We uncovered targets which we will further validate as biomarkers and new therapeutic targets to optimize graft kidney quality before transplantation and improve whole transplantation outcome.
