Case-matched comparison of long-term results of non-heart beating and heart-beating donor renal transplants.
ABSTRACT Function and survival of non-heart-beating donor (NHBD) renal transplants have been shown to be comparable to those from heart-beating donors (HBDs) up to 10 years after transplantation. However, there are few data on outcome after 10 years, particularly from uncontrolled NHBD donors.
All NHBD renal transplants (predominantly uncontrolled) performed between April 1992 and January 2002 were retrospectively matched with HBD renal transplants performed over the same period.
Some 112 NHBD renal transplants were compared with 164 HBD renal transplants. Delayed graft function was significantly higher in the NHBD group (83.9 versus 22.0 per cent respectively; P < 0.001). Primary non-function rates were similar (5.4 versus 1.8 per cent respectively; P = 0.164). Overall serum creatinine was significantly higher in NHBDs (P < 0.001). Median graft and patient survival was 126 months for NHBD and 159 months for HBD kidneys. Death-censored graft survival at 1, 5, 10 and 15 years was respectively 91.8, 77.5, 61.0 and 44.2 per cent for NHBD, and 91.1, 86.3, 71.7 and 58.5 per cent for HBD kidneys (P = 0.108).
Despite increased delayed graft function rates and serum creatinine levels, the long-term survival of NHBD renal transplants was similar to those from HBDs. However, there was a trend to poorer function and survival from 10 years after transplant.

ABSTRACT: There is no national policy for allocation of kidneys from Donation after circulatory death (DCD) donors in the UK. Allocation is geographical and based on individual/regional centre policies. We have evaluated the short term outcomes of paired kidneys from DCD donors subject to this allocation policy.BMC Nephrology 05/2014; 15(1):83. · 1.64 Impact Factor

ABSTRACT: Extracorporeal membranous oxygenation is proposed for abdominal organ procurement from donation after circulatory determination of death (DCD). In France, the national Agency of Biomedicine supervises the procurement of kidneys from DCD, specifying the durations of tolerated warm and cold ischemia. However, no study has determined the optimal conditions of this technique. The aim of this work was to develop a preclinical model of DCD using abdominal normothermic oxygenated recirculation (ANOR). In short, our objectives are to characterize the mechanisms involved during ANOR and its impact on abdominal organs.Transplantation research. 01/2014; 3:13.

ABSTRACT: Delayed graft function and primary non-function are serious complications following transplantation of kidneys derived from deceased brain dead (DBD) donors. α-melanocyte stimulating hormone (α-MSH) is a pleiotropic neuropeptide and its renoprotective effects have been demonstrated in models of acute kidney injury. We hypothesized that α-MSH treatment of the recipient improves early graft function and reduces inflammation following DBD kidney transplantation. Eight Danish landrace pigs served as DBD donors. After four hours of brain death both kidneys were removed and stored for 18 hours at 4°C in Custodiol preservation solution. Sixteen recipients were randomized in a paired design into two treatment groups, transplanted simultaneously. α-MSH or a vehicle was administered at start of surgery, during reperfusion and two hours post-reperfusion. The recipients were observed for ten hours following reperfusion. Blood, urine and kidney tissue samples were collected during and at the end of follow-up. α-MSH treatment reduced urine flow and impaired recovery of glomerular filtration rate (GFR) compared to controls. After each dose of α-MSH, a trend towards reduced mean arterial blood pressure and increased heart rate was observed. α-MSH did not affect expression of inflammatory markers. Surprisingly, α-MSH impaired recovery of renal function in the first ten hours following DBD kidney transplantation possibly due to hemodynamic changes. Thus, in a porcine experimental model α-MSH did not reduce renal inflammation and did not improve short-term graft function following DBD kidney transplantation.PLoS ONE 01/2014; 9(4):e94609. · 3.53 Impact Factor
