Abstract
Solid organ transplantation was one of the greatest medical advances during the past few
decades. Organ preservation solutions have been applied to diminish ischemic/hypoxic
injury during cold storage and improve graft survival. In this article, we provide a
general review of the history and advances of preservation solutions for kidney
transplantation. Key components of commonly used solutions are listed, and effective
supplementations for current available preservation solutions are discussed. At cellular
and molecular levels, further insights were provided into the pathophysiological
mechanisms of effective ingredients against ischemic/hypoxic renal injury during cold
storage. We pay special attention to the cellular and molecular events during
transplantation, including ATP depletion, acidosis, mitochondrial dysfunction, oxidative
stress, inflammation, and other intracellular mechanisms.

Abstract
BACKGROUND The use of non-heart-beating donors (NHBD) has come into practice to resolve the shortage of donor lungs. This study investigated whether hypothermic machine perfusion (HMP) can improve the quality of NHBD lungs. METHODS An uncontrolled NHBD model was achieved in male Lewis rats. Ninety minutes after cardiac arrest, HMP was performed for 60 min at 6°C to 10°C. The first study investigated the physiological lung functions during HMP and the lung tissue energy levels before and after HMP. The second study divided the rats into three groups (n=6 each): no ischemia group; 90-min warm ischemia+60-min HMP+120-min static cold storage (SCS) (HMP group); and 90-min warm ischemia+180-min SCS group. All lungs were reperfused for 60 min at 37°C. Lung functions were evaluated at given timings throughout the experiments. Oxidative damage during reperfusion was evaluated immunohistochemically with a monoclonal antibody against 8-hydroxy-2'-deoxyguanosine. RESULTS The first study revealed that lung functions were stable during HMP. Lung tissue energy levels decreased during warm ischemia but were significantly increased by HMP (P<0.05). The second study confirmed that HMP significantly decreased pulmonary vascular resistance, increased pulmonary compliance, and improved pulmonary oxygenation. The ratio of 8-hydroxy-2'-deoxyguanosine positive cells to total cells significantly increased in the SCS group (P<0.01). CONCLUSIONS Short-term HMP improved lung tissue energy levels that decreased during warm ischemia and ameliorated ischemia-reperfusion injury with decreased production of reactive oxygen species.

Abstract
Endothelin (ET)-1 is a potent vasoconstrictor peptide with pro-inflammatory, mitogenic, and pro-fibrotic properties that is closely involved in both normal renal physiology and pathology. ET-1 exerts a wide variety of biological effects, including constriction of cortical and medullary vessels, mesangial cell contraction, stimulation of extracellular matrix production, and inhibition of sodium and water reabsorption along the collecting duct, effects that are primarily mediated in an autocrine/paracrine manner. Increasing evidence indicates that the ET system is involved in an array of renal disorders. These comprise chronic proteinuric states associated with progressive glomerular and tubulointerstitial fibrosis, including diabetic and hypertensive nephropathy, glomerulonephritis and others. In addition, ET-1 is causally linked to renal disorders characterized by increased renal vascular resistance, including acute ischaemic renal failure, calcineurin inhibitor toxicity, endotoxaemia, hepatorenal syndrome and others. Furthermore, derangement of the ET system may be involved in conditions associated with inappropriate sodium and water retention; for example, in congestive heart failure and hepatic cirrhosis. Both selective and non-selective ET receptor antagonist have been developed and tested in animal models with promising results. As key events in progressive renal injury like inflammation and fibrosis are mediated via both ET(A) and ET(B) receptors, while constrictor effects are primarily transduced by ET(A) receptors, dual ET receptor blockade may be superior over selective ET(A) antagonism. Several compounds have been developed with remarkable effects in several models of acute and progressive renal injury. Thus, clinical studies are required to assess whether these results can be confirmed in humans, hopefully leading to novel and effective therapeutic options with few side effects.

Abstract
BACKGROUND Donation of kidneys from non-heart beating donors (NHBD) is increasingly being used to expand the donor pool. Warm ischemic injury of these kidneys suffered at harvest results in DGF at transplantation. In this study, we used hypothermic continuous machine perfusion preservation to mitigate this injury using two available solutions. METHODS Dog kidneys (beagles) were exposed to 0, 60, or 75 min of in situ warm ischemia (37 degrees C), followed by 24 to 72 hr preservation by machine perfusion with Belzer MPS solution or the UW-solution (Viaspan). Auto-transplantation was performed with immediate contralateral nephrectomy. Survival and renal function (serum creatinine) were evaluated for up to 10 days posttransplant. RESULTS Both solutions were equally effective for 72 hr machine perfusion preservation of dog kidneys giving 100% survival with only minor renal injury. Both solutions were also equally effective for preservation of kidneys exposed to 60 min of warm ischemia. However, only the UW solution gave reliable preservation (86% survival vs. 25% survival) in kidneys exposed to 75 min of warm ischemia and 24 hr machine perfusion. CONCLUSION UW solution used with continuous hypothermic machine perfusion preservation can rescue canine kidneys from severe warm ischemic injury.

Abstract
Therapeutic drug monitoring (TDM) of immunosuppressive therapy is becoming an increasingly complex matter as the number of compounds and their respective combinations are continuously expanding. Unfortunately, in clinical practice, monitoring predose trough blood concentrations is often not sufficient for guiding optimal long-term dosing of these drugs. The excellent short-term results obtained nowadays in renal transplantation confer a misleading feeling of safety despite the fact that long-term results have not substantially improved, definitely not to a point where longer graft survival could counteract the increasing need for transplant organs and less toxicity and side-effects could ameliorate patient survival. It is therefore a challenging task to try to tailor immunosuppressive drug therapy to the individual patient profile and this in a time-dependent manner. For the majority of currently used immunosuppressive drugs, measurement of total drug exposure by determination of the dose-interval area under the concentration curve (AUC) seems to provide more useful information for clinicians in terms of concentration-exposure and exposure-response as well as reproducibility. To simplify this laborious way of measuring drug exposure, several validated abbreviated AUC profiles, accurately predicting the dose-interval AUC, have been put forward. Together with an increasing knowledge of the time-related pharmacokinetic behaviour of immunosuppressive drug and their metabolites, studies are focusing on how to apply abbreviated AUC sampling methods in clinical transplantation, taking into account the numerous factors affecting drug pharmacokinetics. Eventually, TDM using abbreviated AUC profiles has to be prospectively tested against classic methods of drug monitoring in terms of cost-effectiveness, feasibility and clinical relevance with the ultimate goal of improving patient and graft survival.

Abstract
BACKGROUND HMG-CoA reductase inhibitors have been shown to have beneficial renal hemodynamic effects by increasing renal blood flow, independent of their lipid-lowering properties. Currently in organ transplantation, the calcineurin inhibitor cyclosporine A (CyA) is the immunosuppressant of choice. However, its use is limited by its nephrotoxic effects, namely its renal vasoconstrictor properties. The purpose of this study was to determine the effect of an HMG-CoA reductase inhibitor, simvastatin (Zocor), on renal function in rats and on urinary nitrite/nitrate production following ischemia/reperfusion injury (I/R) with concomitant cyclosporine treatment. In addition, L-NAME (N(G)-nitro-L-arginine methyl ester) and L-arginine were administered with CyA to the rats to test the hypothesis that simvastatin's beneficial effects were due to nitric oxide. METHODS Male Wistar rats (250 g) were anesthetized and the supra-aorta clamped for 40 minutes. The right kidney was removed. After recovery, the rats were divided into five groups: 1) controls, no ischemia, no treatment (CTRL, n = 8); 2) ischemia (ISCH) plus cyclosporine A only (CyA, 5 mg/kg/day i.p., n = 8); 3) ischemia plus CyA and simvastatin (SIM, 10 mg/kg/day, gavage, n = 8); 4) ischemia plus simvastatin plus L-NAME plus CyA (10 mg/kg/day, gavage, n = 8), and 5) ischemia plus simvastatin plus L-arginine (2% in drinking water, n = 7) plus CyA. Five to 7 days after I/R injury, the glomerular filtration rate (GFR) was determined using urinary iohexol clearance. Urinary nitrite/nitrate production was determined using nitrate reductase and the Greiss reaction. Data are expressed as mean +/- SEM, and intergroup comparisons were made using one-way analysis of variance. RESULTS The GFR values (mL/min) for all five groups are as follows: 1) CTRL = 1.25 +/- 0.10; 2) ISCH plus CyA only = 0.45 +/- 0.06 (P < 0.05 versus CTRL, ISCH only and simvastatin and cyclosporine and simvastatin plus L-arginine and cyclosporine); 3) CyA and SIM = 0.78 +/- 0.09, CyA and L-NAME = 0.62 +/- 0.12, and CyA and L-arginine and SIM = 1.57 +/- 0.12. Results in the control were significantly different from results in the ischemic only and the L-NAME groups (P < 0.05). The L-arginine plus cyclosporine and simvastatin group was significantly higher than the ischemic only group, ischemic plus simvastatin and cyclosporine and the L-NAME plus cyclosporine group (P < 0.05). No significant differences could be detected in the urinary nitric oxide concentrations. CONCLUSIONS : After I/R injury and cyclosporine treatment, simvastatin and L-arginine preserved renal function, compared with cyclosporine treatment alone, because simvastatin and L-arginine may not have a direct vasoconstrictor effect on the renal microcirculation. They may be suppressing endothelin or increasing other vasodilator mediators such as the vasodilator prostaglandins and/or nitric oxide.

Abstract
The nuclear enzyme poly(ADP-ribose) polymerase (PARP) has been implicated in ischemia-reperfusion injury in many tissues under normothermic conditions. The purpose of this study was to determine whether PARP contributes to mechanisms of the hypothermic ischemia-reperfusion injury that occurs when kidneys are cold stored for transplantation. Cortical tissue slice PARP enzyme activity rose significantly with prolonged cold storage and was dependent on both reperfusion and preservation quality. However, prior exposure to warm ischemia abrogated this increase. PARP protein increased with cold storage but was not dependent on reperfusion. PARP enzyme activity rose quickly after reperfusion in buffer and was not different when whole blood was used. Addition of exogenous hydrogen peroxide (3 mM) to normal renal slices significantly increased PARP activity over 4 h in the cortex but not in the medulla, but the medullary basal PARP synthesis rate was five times higher than that in the cortex. However, the reactive oxygen species (ROS) inhibitors catalase (2,000 U/ml), Trolox (200 microM), and DMSO (15 mM) did not reduce reperfusion-induced PARP activity in cold-stored cortical slices. Finally, PARP inhibitors potentiated preservation injury in isolated canine proximal renal tubules. In conclusion, canine renal PARP enzyme activity rises with prolonged cold storage after reperfusion and may play a protective rather than an injurious role in hypothermic preservation for transplantation. ROS are sufficient but not necessary to activate PARP under these conditions.

Abstract
OBJECTIVES To determine the effect of cyclosporine and rapamycin administration on renal function after ischemia/reperfusion injury (I/R). Cyclosporine A has known nephrotoxic effects. Thus, cyclosporine therapy subsequent to I/R injury may further exacerbate graft dysfunction. Rapamycin is a newer agent that suppresses the immune system by a different mechanism. METHODS Male Wistar rats (250 g) were anesthetized, and the suprarenal aorta was clamped for 40 minutes. The right kidney was removed. After recovery, the rats were divided into four groups: group 1, controls, no ischemia and no treatment (n = 10); group 2, ischemia with no treatment (n = 8); group 3, ischemia plus rapamycin (0.17 mg/kg/day gavage, n = 8); and group 4, ischemia plus cyclosporine A (30 mg/kg/day intraperitoneally, n = 9). The glomerular filtration rate was measured 5 to 7 days after I/R injury using urinary iohexol clearance. Data are expressed as the mean +/- SEM, and intergroup comparisons were made using one-way analysis of variance. RESULTS The mean GFR value for the controls (no ischemia, no treatment) was 1.23 +/- 0.08 mL/min; for group 2 (ischemia, no treatment), it was 1.05 +/- 0.10 mL/min; for group 3 (ischemia plus rapamycin) 1.06 +/- 0.14 mL/min; and for group 4 (ischemia plus cyclosporine A) 0.44 +/- 0.06 mL/min (P <0.05 versus the other three groups). The mean arterial pressure was significantly lower in the ischemic rats treated with cyclosporine A (P <0.05 versus the other three groups). CONCLUSIONS After I/R injury, rapamycin may preserve renal function compared with cyclosporine treatment, because it does not have a direct vasoconstrictor effect on the renal microcirculation.

In organ transplantation, the calcineurin inhibitor cyclosporine A (CyA) is the immunosuppressant of choice. However, its renal vasoconstrictor properties limit its use. This study aimed to determine the effect of an HMG-CoA reductase inhibitor, simvastatin (Zocor), on renal function in rats after ischemia/reperfusion injury (I/R) with concomitant CyA treatment. METHODS Male Wistar rats (250 g) were anesthetized and the suprarenal aorta clamped for 40 minutes. The right kidney was removed. After recovery, the rats were divided into 5 groups: (1) control rats, no ischemia, no treatment; (2) ischemia with no treatment; (3) ischemia plus CyA only; (4) ischemia plus CyA and low-dose simvastatin; and (5) ischemia plus CyA and high-dose simvastatin. Five to 7 days after I/R injury, glomerular filtration rate (GFR) was determined using urinary iohexol clearance. RESULTS The GFR values (mL/min) for all 5 groups were as follows: (1) 1.23 +/- 0.08; (2) 1.05 +/- 0.10; (3) 0.44 +/- 0.06 (P < 0.05 versus groups 1, 2, and 5; one-way analysis of variance); (4) 0.51 +/- 0.04 (P < 0.05 versus groups 1, 2, and 5; one-way analysis of variance); and (5) 0.85 +/- 0.11. CONCLUSIONS After I/R injury and cyclosporine treatment, simvastatin preserved renal function compared with cyclosporine treatment alone because it may not have a direct vasoconstrictor effect on the renal microcirculation. In fact, it may exhibit vasodilator properties on the renal microcirculation mediated by nitric oxide.

Abstract
BACKGROUND Ischemia-reperfusion injury has been established as a nonimmunologic risk factor for the development of chronic graft nephropathy after renal transplantation. This objective of this study was to determine if oral administration of an endothelin-1 receptor (ET-R) antagonist over a 2-month period after renal transplantation would mitigate long-term dysfunction associated with 30 min of preretrieval warm ischemia (pre-WI). METHODS The left kidney was retrieved from 250-g Lewis rats. Recipients underwent left nephrectomy and isografting using standard techniques. Animals were divided into three groups: nonischemic controls (no pre-WI, n=8); ischemic controls (pre-WI only, n=6); and pre-WI kidneys in which recipients received the ET(A/B) receptor antagonist, A182086, daily (30 mg/kg/day) (pre-WI/ET-R antagonist, n=6). Isograft glomerular filtration rate (GFR) was measured at 2 months. RESULTS Measurement of GFR (mL/min) were as follows: no pre-WI, 2.1+/-0.26; pre-WI only, 1.24+/-0.14 (P<0.05 vs. no pre-WI); and pre-WI/ET-R antagonist, 2.3+/-0.45 (P<0.05 vs. pre-WI only and P=NS vs. no pre-WI). CONCLUSIONS Chronic administration of a nonselective ET-R antagonist given after the ischemic insult, mitigated the decline in GFR at 2 months. These observations provide an experimental rationale for further investigation of the potential long-term protective effect of nonselective ET-R blockade versus ischemia-reperfusion injury in the clinical setting.
