Abstract
Cellular damage after reperfusion of ischaemic tissue is defined as ischaemia–reperfusion injury (IRI). Hypothermia is able to decrease oxygen consumption, preventing a rapid loss of mitochondrial activity. However, even though cooling can help to decrease the deleterious effects of ischaemia, the consequences are not exclusively beneficial, such that hypothermic storage is a compromise between benefits and harm. The present review details the relationship between renal IRI and hypothermia, describing the pathophysiology of IRI and hypothermic protection through experimental evidence. Although experimental models of renal IRI are a valuable tool for understanding the pathophysiology of renal ischaemia–reperfusion, the clinical transfer of experimental results has several limitations, particularly because of anatomical and physiological differences. In this review limitations of animal models but also hypothermia as a strategy to protect the kidney from IRI are discussed. We also attempt to describe three clinical scenarios where hypothermia is used in clinical settings of IRI: transplantation, deceased donors and post-cardiac arrest.

[PMID: 25540738 PMCID: PMC4274599 DOI: 10.5500/wjt.v4.i4.299] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2014] [Revised: 07/08/2014] [Accepted: 11/03/2014] [Indexed: 02/05/2023] Open
Abstract
AIM: To investigate the effects of 1400W-a selective inducible nitric oxide synthase (iNOS) inhibitor in a model of donation after circulatory death (DCD) kidneys.
METHODS: Porcine kidneys were retrieved after 25 min warm ischemia. They were then stored on ice for 18 h before being reperfused ex vivo with oxygenated autologous blood on an isolated organ perfusion system. The selective iNOS inhibitor 1400W (10 mg/kg) was administered before reperfusion (n = 6) vs control group (n = 7). Creatinine (1000 μmol/L) was added to the system, renal and tubular cell function and the level of ischemia reperfusion injury were assessed over 3 h of reperfusion using plasma, urine and tissue samples.
RESULTS: Kidneys treated with 1400W had a higher level of creatinine clearance (CrCl) [area under the curve (AUC) CrCl: 2.37 ± 0.97 mL/min per 100 g vs 0.96 ± 0.32 mL/min per 100 g, P = 0.004] and urine output [Total: 320 ± 96 mL vs 156 ± 82 mL, P = 0.008]. There was no significant difference in levels of fractional excretion of sodium (AUC, Fr ex Na+: Control, 186.3% ± 81.7%.h vs 1400W, 153.4% ± 12.1%.h, P = 0.429). Levels of total protein creatinine ratio were significantly lower in the 1400W group after 1 h of reperfusion (1h Pr/Cr: 1400W 9068 ± 6910 mg/L/mmol/L vs Control 21586 ± 5464 mg/L/mmol/L, P = 0.026). Levels of 8-isoprostane were significantly lower in the 1400W group [8-iso/creatinine ratio: Control 239 ± 136 pg/L/mmol/L vs 1400W 139 ± 47 pg/L/mmol/L, P = 0.041].
CONCLUSION: This study demonstrated that 1400W reduced ischaemia reperfusion injury in this porcine kidney model of DCD donor. Kidneys had improved renal function and reduced oxidative stress.

Abstract
Toll-like receptor-4 (TLR-4) has been increasingly recognized as playing a critical role in the pathogenesis of ischemia-reperfusion injury (IRI) of renal grafts. This review provides a detailed overview of the new understanding of the involvement of TLR-4 in ischemia-reperfusion injury of renal grafts and its clinical significance in renal transplantation. TLR-4 not only responds to exogenous microbial motifs but can also recognize molecules which are released by stressed and necrotic cells, as well as degraded products of endogenous macromolecules. Upregulation of TLR-4 is found in tubular epithelial cells, vascular endothelial cells, and infiltrating leukocytes during renal ischemia-reperfusion injury, which is induced by massive release of endogenous damage-associated molecular pattern molecules such as high-mobility group box chromosomal protein 1. Activation of TLR-4 promotes the release of proinflammatory mediators, facilitates leukocyte migration and infiltration, activates the innate and adaptive immune system, and potentiates renal fibrosis. TLR-4 inhibition serves as the target of pharmacological agents, which could attenuate ischemia-reperfusion injury and associated delayed graft function and allograft rejection. There is evidence in the literature showing that targeting TLR-4 could improve long-term transplantation outcomes. Given the pivotal role of TLR-4 in ischemia-reperfusion injury and associated delayed graft function and allograft rejection, inhibition of TLR-4 using pharmacological agents could be beneficial for long-term graft survival.

Abstract
Mouse renal transplantation is a technically challenging procedure. Although the first kidney transplants in mice were performed over 34 years ago and refined some years later, the classical techniques of mouse renal transplantation required clamping both vena cava and aorta simultaneously and carry out suture anastomoses of the renal artery and vein in a heterotopic position. In our laboratory, we have successfully developed mouse orthotopic kidney transplantation for the first time, using a rapid "cuffed" renal vein technique for vessel anastomosis, wherein the donor's renal vein was inserted through an intravenous catheter, folded back and tied. During grafting, the cuffed renal vein was directly inserted into the recipient's renal vein without the need for the clamping vena cava and suturing of renal vein. This technique allowed for the exact transplantation of the kidney into the original position, compared to the classical technique, and has significantly shortened the clamping time due to a quicker and precise anastomosis of renal vein as described. This also allowed for a quicker recovery of the lower extremity activity, reduction in myoglobinuria with resultant kidney graft survival of 88.9%. Thus we believe that the cuffed renal vein technique simplifies microvascular anastomoses and affords important additional benefits.

Abstract
PURPOSE Mouse kidney transplantation is a challenging technique for novice microsurgeons. Factors that affect transplant outcomes for a clinical surgeon starting microsurgery have not yet been investigated. MATERIALS AND METHODS 110 consecutive mouse kidney transplants were performed over a 9-month period. Data were recorded, and surgical results and complication were analyzed. RESULTS Three and thirty day survival rates improved from 0 (0/6) to 92.3 % (12/13) between months 1 and 9. Bleeding, arterial thrombosis, kidney failure and hydronephrosis were the most common causes of transplant failure. From month 1 to month 7, using the same surgical technique, practice significantly decreased the incidence of bleeding and increased the 3-day survival rate; however, it didn't significantly decrease the incidence of thrombosis, kidney failure, but improved the 30-day survival rate. From month 8, when surgical technique used on artery anastomosis switched from continuous suture to interrupted suture, surgical survival rate at 3 and 30 days improved significantly. Interestingly, ischemia time was not a significant factor determining the success of transplantation in this study. CONCLUSIONS Practice is essential for novice microsurgeons, and the choice of surgical techniques significantly affects surgical results. The use of interrupted arterial sutures can significantly improve mouse kidney transplantation outcomes compared with continuous sutures. Ischemic time was not a factor in determining successful of kidney transplantation in mice in this study.

Abstract
Abstract
Background
Combining hypothermic techniques, as a more practical approach to preservation, may enhance the condition of kidneys donated after cardiac death.
Methods
Porcine kidneys were retrieved after 10 min in situ warm ischaemia, then preserved by either 18 h static cold storage (CS), hypothermic machine perfusion for 18 h (HMP) or 14 h static CS followed by 4 h HMP (4HMP). Kidneys were reperfused for 3 h with oxygenated autologous blood on an isolated organ perfusion system to assess renal function and injury.
Results
Intrarenal resistance was significantly higher in the 4HMP group than in the CS and HMP groups: mean(s.d.) area under the curve (AUC) 8·48(2·97), 3·41(1·80) and 3·78(1·68) mmHg/min.h respectively (P = 0·011). Creatinine clearance was lower after 4HMP and CS: AUC 2·3(0·6) and 2·2(1·7) ml per min per 100g.h respectively versus 9·8(7·3) ml per min per 100g.h in the HMP group (P = 0·022). Levels of endothelin 1 were higher in the 4HMP and CS groups: mean(s.d.) 21·6(4·0) and 24·2(2·3) pg/ml respectively versus 11·4(4·6) pg/ml in the HMP group (P = 0·002). Morphological damage was increased in the 4HMP group.
Conclusion
This porcine kidney study demonstrated no advantage to the addition of 4 h of HMP after CS.

Abstract
PURPOSE OF REVIEW Biological modulation of renal ischemia-reperfusion injury holds the potential to reduce the incidence of early graft dysfunction and to safely expand the donor pool with kidneys that have suffered prolonged ischemic injury before organ recovery. RECENT FINDINGS In the current review, we will discuss clinical studies that compare kidney transplant recipients with and without early graft dysfunction in order to elucidate the pathophysiology of ischemic acute allograft injury. We will specifically review the mechanisms leading to depression of the glomerular filtration rate and activation of the innate immune system in response to tissue injury. SUMMARY We conclude that the pathophysiology of delayed graft function after kidney transplantation is complex and shares broad similarity with rodent models of ischemic acute kidney injury. Given the lack of specific therapies to prevent delayed graft function in transplant recipients, comprehensive efforts should be initiated to translate the promising findings obtained in small animal models into clinical interventions that attenuate ischemic acute kidney injury after transplantation.

Abstract
BACKGROUND : Therapies to alleviate ischaemia-reperfusion (IR) injury have an important role in kidney transplantation. This study used a porcine model of non-heart-beating (NHB) donor kidneys to investigate the effects of hydrogen sulphide on IR injury. METHODS : Porcine kidneys were subjected to 25 min of warm ischaemia and 18 h of cold storage. They were reperfused ex vivo with autologous oxygenated blood to assess renal function. A group treated with hydrogen sulphide (0.5 mmol/l) infused 10 min before and after reperfusion (n = 6) was compared with an untreated control group (n = 7). RESULTS : Hydrogen sulphide significantly improved renal blood flow compared with control values (mean(s.d.) area under the curve (AUC) 614.9(165.5) versus 270.3(86.7) ml per min per 100 g.h; P = 0.001) and renal function (AUC creatinine: 1640(248) versus 2328(154) micromol/l.h; P = 0.001; AUC creatinine clearance: 6.94(5.03) versus 0.96(0.32) ml per min per 100 g.h; P = 0.004). Oxidative damage was also reduced by hydrogen sulphide (urinary 8-isoprostane at 1 h of reperfusion: 478.9(237.1) versus 1605.6(632.7) pg/ml per mmol/l creatinine; P = 0.032). CONCLUSION : Hydrogen sulphide ameliorated the renal dysfunction associated with ischaemic damage, and has potential as a therapy against IR injury in NHB donor kidney transplantation.

Abstract
Abstract
Background
Nitric oxide and carbon monoxide exert vasodilatory effects that minimize ischaemia–reperfusion injury. An isolated porcine kidney model was used to assess the effects of administering the nitric oxide donor sodium nitroprusside (SNP) and carbon monoxide-releasing molecule (CORM) 3 during a period of warm preservation followed by reperfusion.
Methods
Kidneys were perfused under warm preservation conditions after 10 min of warm ischaemia and 16 h of cold storage in four groups: SNP, control, CORM-3 and inactive CORM-3 (inactive control). Renal function and viability were assessed.
Results
SNP and CORM-3 increased renal blood flow (RBF) during warm preservation (P = 0·014). After reperfusion, RBF was significantly improved in the CORM-3 group compared with the control group (P = 0·019). The reduction in creatinine clearance was significantly less in the CORM-3 group than in the inactive CORM-3 group (P = 0·021), and serum creatinine levels were significantly lower (P = 0·029). There was a negative correlation between RBF during warm preservation and functional parameters during reperfusion (creatinine concentration: rs = − 0·722, P < 0·001; sodium excretion: rs = − 0·912, P < 0·001).
Conclusion
The beneficial vasodilatory effects of CORM-3 during warm preservation improved renal function during reperfusion; SNP exerted similar, although less pronounced, effects.

Abstract
Ischemia-reperfusion injury is one of the central nonimmunologic processes involved in renal allograft dysfunction. Kidneys from non-heart beating donors (NHBD) exhibit higher rates of delayed graft function (DGF) than those from other donors. Primary nonfunction and DGF are the main barriers to the use of kidneys from NHBD. Using a pig model of NHBD transplantation, we studied the effect of FR167653 (a p38 MAP kinase inhibitor) on the recovery and reparation of kidneys exposed to both warm (WI: 1 h) and cold ischemia (24 h). Our results demonstrate that the addition of FR167653 increases the kinetics of proximal tubule cell regeneration after 60 min of WI. Hypoxia-inducible factor and vascular endothelial growth factor expression was also more important in FR167653-treated kidneys compared with those in nontreated groups. Also, expression of peripheral-type benzodiazepine receptor, involved in tissue repair, was increased in the FR167653-treated groups. At 3 mo, the protective effects of FR167653 were accompanied by a reduction of long-term inflammation process and tubulointerstitial fibrosis development associated with a limitation of ischemia-induced remodeling. This study suggests that such treatment may be useful in protocols aimed at improving the quality of renal transplants from NHBD. In addition, the beneficial role of FR167653 in limiting early injury is associated with secondary reduction in development of tubular atrophy and interstitial fibrosis which are together the hallmark of failing renal transplants. The more efficient effect was observed when FR167653 was added in combination before WI, during cold storage and reperfusion.

Abstract
When transplantation started all organs were retrieved from patients immediately after cardio-respiratory arrest, i.e. from non heart-beating donors. After the recognition that death resulted from irreversible damage to the brainstem, organ retrieval rapidly switched to patients certified dead after brainstem testing. These heart-beating-donors have become the principal source of organs for transplantation for the last 30 years. The number of heart-beating-donors are declining and this is likely to continue, therefore cadaveric organs from non-heart-beating donor offers a large potential of resources for organ transplantation. The aim of this study is to examine clinical outcomes of non-heart-beating donors in the past 10 years in the UK as an way of decreasing pressure in the huge waiting list for organs transplantation.
