Introduction: Many European countries have transplant programs with controlled donors after cardiac death (cDCD). Twenty-two centers are part of GEODAS group. We analyzed clinical results from a nephrological perspective. Methods: Observational, retrospective and multicentre study with systematic inclusion of all kidney transplant recipients from cDCD, following local protocols regarding extraction and immunosuppression. Results: A total of 335 cDCD donors (mean age 57.2 years)whose deaths were mainly due to cardiovascular events were included. Finally, 566 recipients (mean age 56.5 years; 91.9% first kidney transplant)were analyzed with a median of follow-up of 1.9 years. Induction therapy was almost universal (thymoglobulin 67.4%; simulect 32.8%)with maintenance with prednisone-MMF-tacrolimus (91.3%)or combinations with mTOR (6.5%). Mean cold ischemia time (CIT)was 12.3 h. Approximately 3.4% (n = 19)of recipients experienced primary non-function, essentially associated with CIT (only CIT = 14 h was associated with primary non-function). Delayed graft function (DGF)was 48.8%. DGF risk factors were CIT = 14 h OR 1.6, previous haemodialysis (vs. peritoneal dialysis)OR 2.1 and donor age OR 1.01 (per year). Twenty-one patients (3.7%)died with a functioning graft, with a recipient and death-censored graft survival at 2-years of 95% and 95.1%, respectively. The estimated glomerular filtration rate at one year of follow-up was 60.9 ml/min. Conclusions: CIT is a modifiable factor for improving the incidence of primary non-function in kidney transplant arising from cDCD. cDCD kidney transplant recipients have higher delayed graft function rate, but the same patient and graft survival compared to brain-dead donation in historical references. These results are convincing enough to continue fostering this type of donation. Introducción: Varios países europeos disponen de programas de donación tras parada cardiaca controlada (cDCD). Veintidós centros participan en el grupo GEODAS, cuyos resultados clínicos presentamos desde una perspectiva nefrológica. Métodos: Estudio multicéntrico retrospectivo observacional con inclusión sistemática de todos los trasplantes renales (TR) procedentes de cDCD, siguiendo protocolos locales de extracción e inmunosupresión. Resultados: Se incluyó a 335 donantes tras cDCD (edad media 57, 2 años) fallecidos mayoritariamente por eventos cardiovasculares. Se analizan 566 receptores (edad media de 56, 5 años; el 91, 9% con primer trasplante renal), con una mediana de seguimiento de 1, 9 años. La terapia de inducción fue casi universal (timoglobulina 67, 4%; simulect 32, 8%) con mantenimiento con prednisona-MMF-tacrolimus (91, 3%) o combinaciones con mTOR (6, 5%). El tiempo medio de isquemia fría (CIT) fue 12, 3 h. Hubo un 3, 4% de fallo primario del injerto (n = 19), asociado fundamentalmente al tiempo de isquemia fría (solo el CIT = 14 h se asoció a fallo primario del injerto). La función retrasada del injerto (DGF) fue 48, 8%. Los factores de riesgo para la DGF fueron: CIT = 14 h OR 1, 6, procedencia de hemodiálisis (vs. diálisis peritoneal) OR 2, 1 y edad del donante OR 1, 01 (por año). Veintiún pacientes fallecieron con injerto funcionante (3, 7%), con una supervivencia de paciente e injerto (censurada para muerte) al segundo año del 95% y del 95, 1%, respectivamente. El filtrado glomerular estimado al año de seguimiento fue 60, 9 ml/min. Conclusiones: El CIT es un factor modificable para mejorar la incidencia del fallo primario del injerto en trasplante renal procedente de cDCD. El trasplante renal con cDCD tiene mayor incidencia en la función retrasada del injerto, pero igual supervivencia de paciente e injerto que la referencia histórica para donación en muerte encefálica. Los resultados son satisfactorios para continuar promoviendo este tipo de donación.

Introducción: La disponibilidad de donantes es el factor limitante para el trasplante renal. El donante en asistolia (DAS) no controlado proporciona hasta un tercio de los órganos. El DAS controlado tras limitación de técnicas de soporte vital (LTSV) o tipo III de Maastricht constituye una alternativa aún por desarrollar de forma sistemática. Tipo de estudio: Descriptivo, serie de 10 casos realizados entre enero y abril 2012. Métodos: A lo largo de 6 meses se diseña el protocolo de extracción y manejo del trasplante e inmunosupresión entre los equipos implicados. Se evalúan los pacientes de acuerdo con los criterios consensuados por un equipo distinto al responsable de coordinación de trasplante. Se establece un tiempo máximo 120 min desde LTSV hasta fallecimiento y de 60 min de isquemia caliente. Se utilizan dos tipos de perfusión de injerto, uno in situ por abordaje directo en lecho quirúrgico y otro con canalización vascular antemortem. La pauta de inmunosupresión incluye inducción con timoglobulina, esteroides y micofenolato e introducción de tacrolimus al séptimo día. Se muestran datos como mediana y (rango). Resultados: Se incluyen los 10 primeros casos de trasplante renal con órganos procedentes de 5 DAS tipo III de Maastricht: 4 varones, edad media 57 años (45-66), con LTSV por encefalopatía anóxica (2), intoxicación (1), accidente cerebrovascular agudo (2) e insuficiencia respiratoria terminal (1). Los tiempos registrados fueron: isquemia caliente efectiva de 20 min (8-23) e isquemia fría de 7,5 horas (4-14,1). Los receptores tenían 58 años (32-71), con distintas etiologías (2 glomerulonefritis, 1 poliquistosis, 2 nefropatía tubulointersticial, 4 vasculares y 1 no filiada), llevaban en hemodiálisis 31,7 meses (11-84) y para 2 de ellos era su segundo trasplante. Ninguno era hiperinmunizado. Seis pacientes precisaron alguna sesión de diálisis y cuatro presentaron necrosis tubular aguda prolongada, durante un ingreso de 24,5 días (8-44 d). La creatinina (Cr) al mes del trasplante fue de 2,1 mg/dl (0,7-3,2) y la Cr nadir fue de 1,2 mg/dl (0,7-3,2 mg/dl). Un paciente no mejoró su Cr por debajo de 3,2 mg/dl aunque la biopsia no mostró toxicidad ni rechazo, y su pareja de trasplante alcanzó una Cr de 1,4 mg/dl. En toda la serie se constataron complicaciones quirúrgicas similares a las de nuestra serie histórica de donantes convencionales. Conclusiones: Con las limitaciones de un estudio preliminar, el uso de este tipo de injertos presenta una evolución favorable a corto plazo. La utilización de este tipo de donante puede ayudar a reducir el tiempo de espera para un trasplante. Introduction: The availability of organ donors is a limiting factor for kidney transplants. Donations from non-heart-beating donors (NHBD) can provide as many as one-third of all organs. Controlled patients awaiting cardiac arrest following limitation of life support techniques, or type III Maastricht donors, constitute an alternative that still has yet to be systematically developed. Study type: Descriptive series of 10 cases occurring between January and April 2012. Method: Over a period of 6 months, we designed a protocol for extracting and managing kidney transplants and providing immunosuppression therapy. Patients are evaluated in accordance with the criteria agreed by a different team responsible for transplant coordination. We established a maximum duration of time between limitation of life-sustaining therapy and death of 120 minutes and 60 minutes warm ischaemia. Two types of graft perfusion were used, one in situ through direct application to the surgical area, and another using ante mortem vascular canalisation. Immunosuppression therapy included induction with thymoglobulin, steroids, and mycophenolate, with introduction of tacrolimus on the seventh day. Data are expressed as median and (range). Results: We included the first 10 cases of kidney transplants with organs from 5 NHBD (type III Maastricht): 4 males, mean age of 57 years (45-66 years), with limitation of life-sustaining therapy due to anoxic encephalopathy (2), intoxication (1), acute stroke (2) and terminal respiratory failure (1). The following mean time intervals were recorded: effective warm ischaemia: 20 minutes (8-23 minutes) and cold ischaemia: 7.5 hours (4-14.1 hours). Recipients had a mean age of 58 years (32-71 years), with various aetiologies (2 cases of glomerulonephritis, 1 polycystic kidney disease, 2 tubulo-interstitial nephropathy, 4 vascular, and 1 unknown), with a mean 31.7 months on haemodialysis (11-84 months); the kidney was a second transplant in two cases. No patients were hyper-immunised. Six patients required a dialysis session at some point, and four had prolonged acute tubular necrosis, over a mean hospitalisation period of 24.5 days (8-44 days). Mean creatinine (Cr) one month after transplantation was 2.1mg/dl (0.7-3.2mg/dl), and mean nadir creatinine was 1.2mg/dl (0.7-3.2mg/dl). One patient did not improve upon Cr values

Introduction: The availability of organ donors is a limiting factor for kidney transplants. Donations from non-heart-beating donors (NHBD) can provide as many as one-third of all organs. Controlled patients awaiting cardiac arrest following limitation of life support techniques, or type III Maastricht donors, constitute an alternative that still has yet to be systematically developed., Study Type: Descriptive series of 10 cases occurring between January and April 2012., Method: Over a period of 6 months, we designed a protocol for extracting and managing kidney transplants and providing immunosuppression therapy. Patients are evaluated in accordance with the criteria agreed by a different team responsible for transplant coordination. We established a maximum duration of time between limitation of life-sustaining therapy and death of 120 minutes and 60 minutes warm ischaemia. Two types of graft perfusion were used, one in situ through direct application to the surgical area, and another using ante mortem vascular canalisation. Immunosuppression therapy included induction with thymoglobulin, steroids, and mycophenolate, with introduction of tacrolimus on the seventh day. Data are expressed as median and (range)., Results: We included the first 10 cases of kidney transplants with organs from 5 NHBD (type III Maastricht): 4 males, mean age of 57 years (45-66 years), with limitation of life-sustaining therapy due to anoxic encephalopathy (2), intoxication (1), acute stroke (2) and terminal respiratory failure (1). The following mean time intervals were recorded: effective warm ischaemia: 20 minutes (8-23 minutes) and cold ischaemia: 7.5 hours (4-14.1 hours). Recipients had a mean age of 58 years (32-71 years), with various aetiologies (2 cases of glomerulonephritis, 1 polycystic kidney disease, 2 tubulo-interstitial nephropathy, 4 vascular, and 1 unknown), with a mean 31.7 months on haemodialysis (11-84 months); the kidney was a second transplant in two cases. No patients were hyper-immunised. Six patients required a dialysis session at some point, and four had prolonged acute tubular necrosis, over a mean hospitalisation period of 24.5 days (8-44 days). Mean creatinine (Cr) one month after transplantation was 2.1mg/dl (0.7-3.2mg/dl), and mean nadir creatinine was 1.2mg/dl (0.7-3.2mg/dl). One patient did not improve upon Cr values <3.2mg/dl, despite the absence of evidence of toxicity or rejection in a renal biopsy, and the transplant pair reached a Cr of 1.4mg/dl. Throughout the series, similar surgical complications were recorded to those observed in conventional donor situations., Conclusions: Despite the limitations of this preliminary study, the use of this type of transplant produces favourable short-term evolution. Expanded use of this type of donor could reduce the waiting-list time for a kidney transplant.
