BACKGROUND: Children with end-stage kidney disease may have co-existing iatrogenic or congenital vascular anomalies making transplantation difficult. We describe our approach in 5 recipients with vascular anomalies and significant co-morbidities, including one case of blood group incompatibility. METHODS: Five children aged 3 - 17 (median 7) years, weighing 14 - 34 (median 18) kg of whom 4 had occluded inferior vena cava or iliac veins and 2 had previous complex vascular reconstructions prior to transplantation for mid-aortic syndrome and multiple aortic aneurysms, respectively underwent renal transplantation...

BACKGROUND: The course of skin cancer after retransplantation in organ-transplant recipients who have already developed posttransplant skin cancer has not been assessed. METHODS: This retrospective multicentric study included 53 patients with a history of cutaneous squamous cell carcinoma (SCC) after a first kidney transplantation who received a second kidney transplantation. The primary end-point was the occurrence of aggressive cutaneous SCC after the second transplantation...

BACKGROUND: Coronary artery disease (CAD) is a significant problem during evaluation for liver transplantation (LT). We aim to assess survival in LT recipients based on presence, severity, extent of CAD and cardiac events within 90 days of LT. METHODS: 87 LT recipients with history of pre-LT angiogram (12/2005-12/2012) were compared with 2 control groups without prior angiogram, 72 LT recipients matched for cardiovascular risk factors (Control Gr I), and 119 consecutive LT recipients without any CV risk factors (Control Gr II)...

BACKGROUND: Successful pancreas transplantation requires surgical expertise and multidisciplinary medical management. The impact of transplant center volume on pancreas allograft survival remains unclear. METHODS: We examined Organ Procurement and Transplantation Network (OPTN) data on 11,568 simultaneous pancreas-kidney (SPK) and 4308 solitary pancreas (pancreas transplant alone and pancreas after kidney) transplants between 2000 and 2013. RESULTS: Average annual transplant center volume was categorized by tertiles into low, medium and high volume, respectively, as follows: 1-6 (n=3,861), 7-13 (n=3,891), and 14-34 (n=3,888) for SPK, and 1-3 (n=1,417), 4-10 (n=1,518), and 11-33 (n=1,377) for solitary pancreas transplants...

Recent progress in deciphering the mechanisms underlying the concepts of tumor immunosurveillance and immunoevasion has opened new opportunities for the development of effective anti-tumor therapies. Transplant physicians and immunologists have much to learn from those direct clinical translations of basic science. The 2016 Beaune Seminar in Transplant research brought together researchers from both fields to explore and discuss significant advances in cancer biology, immunotherapies and their potential impacts for the management of cancer in transplant recipients...

BACKGROUND: Prerecovery liver biopsy (PLB) allows histological evaluation of the organ prior to procurement. The opinions and what factors might influence PLB use within Organ Procurement Organizations (OPOs) are unknown. METHODS: A survey instrument was distributed by the Association of OPOs to the clinical directors of all 58 OPOs. Descriptive statistics were calculated. Results were also stratified based on OPO characteristics. RESULTS: 84...

BACKGROUND: Creutzfeldt-Jakob disease (CJD) has been accidentally transmitted by contaminated corneal transplants. Eye donors are not ordinarily tested for CJD, in part because an easy test is not available. We propose a relatively simple postmortem procedure to collect brain samples without performing full autopsy and show that a test currently marketed for veterinary diagnosis would offer an effective screening test. METHODS: We selected 6 brains from confirmed cases of human sporadic CJD and sampled each in triplicate (18 specimens), 28 control brains of individuals with non-CJD neurodegenerative diseases and 10 normal brains...

The old-for-old allocation policy used for kidney transplantation (KT) has confirmed the survival benefit compared to remaining listed on dialysis. Shortage of standard donors has stimulated the development of strategies aimed to expand acceptance criteria, particularly of kidneys from elderly donors. We have systematically reviewed the literature on those different strategies. In addition to the review of outcomes of expanded criteria donor (ECD) or advanced age kidneys, we assessed the value of the Kidney Donor Profile Index (KDPI) policy, preimplantation biopsy, dual KT, machine perfusion and special immunosuppressive protocols...

BACKGROUND: Only a limited number of centers have performed laparoscopic living donor hepatectomy to date. In particular, laparoscopic right hepatectomy is rarely performed because the procedure can only be performed by surgeons with significant experience in both laparoscopic liver surgery and liver transplantation with living donor liver grafts. METHODS: Between November 2014 and February 2015, in a pure laparoscopic approach program for living right lobe donors at Asan Medical Center, 92 living donors underwent right hepatectomy for adult living donor liver transplantation (LDLT)...

BACKGROUND: Islet transplantation is an effective therapy in type 1 diabetes and recalcitrant hypoglycemia. However, there is an ongoing need to circumvent islet loss posttransplant. We explore herein the potential of the pan-caspase inhibitor F573, to mitigate early apoptosis-mediated islet death within portal and extrahepatic portal sites in mice. METHODS: Mouse or human islets were cultured in standard media ±100 μM F573 and subsequently assessed for viability and apoptosis via TUNEL staining and caspase-3 activation...

Liver allocation in Eurotransplant is complex as allocation rules need to follow not only the guidelines of the European Commission but also the specific regulations of each of the 7 Eurotransplant countries with active liver transplant programs. Thirty-eight liver transplant centers served a population of about 135 million in 2015. Around 1600 deceased donor livers are transplanted annually. The number of deceased organ donors remains stable but donor age is increasing. Nevertheless, liver utilization rates are unchanged at around 80%...

Liver fibrosis can regress in patients with chronic hepatitis in whom the underlying cause of liver damage is adequately treated. Studies documenting this benefit have been mostly performed in the setting of viral hepatitis, particularly hepatitis C virus (HCV), where sustained viral response (SVR) has been unequivocally shown to result in histological and clinical improvement. With the advent of the new interferon (IFN)-free regimens, highly effective and safe even in those historically considered "difficult to treat and cure patients", additional benefits have been documented in patients treated at advanced stages of disease, including improvement in liver function with hepatic "re-compensation", reduction of portal hypertension, and eventually avoidance of liver transplantation (LT)...

BACKGROUND: Recipients of vascularized composite allografts require aggressive and life-long immunosuppression, and since the surgery is usually performed in nonlife threatening situations, the development of strategies to minimize immunosuppression is especially pertinent for this procedure. We investigated how complement affects acute graft injury, alloimmunity, and immunosuppressive therapy. METHODS: Vascularized composite allografts were transplanted from Balb/C to C57BL/6 mice that were complement deficient (C3 or double C3a Receptor (R)/C5aR), or treated with a targeted complement inhibitor (CR2-Crry)...
