ABSTRACT
The First World Consensus Conference on Pancreas Transplantation provided 49 jury deliberations regarding the impact of pancreas transplantation on the treatment of diabetic patients, and 110 experts' recommendations for the practice of pancreas transplantation. The main message from this consensus conference is that both simultaneous pancreas-kidney transplantation (SPK) and pancreas transplantation alone can improve long-term patient survival, and all types of pancreas transplantation dramatically improve the quality of life of recipients. Pancreas transplantation may also improve the course of chronic complications of diabetes, depending on their severity. Therefore, the advantages of pancreas transplantation appear to clearly surpass potential disadvantages. Pancreas after kidney transplantation increases the risk of mortality only in the early period after transplantation, but is associated with improved life expectancy thereafter. Additionally, preemptive SPK, when compared to SPK performed in patients undergoing dialysis, appears to be associated with improved outcomes. Time on dialysis has negative prognostic implications in SPK recipients. Increased long-term survival, improvement in the course of diabetic complications, and amelioration of quality of life justify preferential allocation of kidney grafts to SPK recipients.

Antithrombin (AT) is a coagulatory inhibitor with pleiotropic activities. AT reduces ischemia/reperfusion injury and has been successfully used in patients with simultaneous pancreas kidney transplantation. This study retrospectively analyzes prophylactic high-dose AT application in patients with solitary pancreas transplantation traditionally related to suboptimal results. In our center, 31 patients received solitary pancreas transplantation between 7/1994 and 7/2005 (pancreas retransplantation, PAK/PTA). The perioperative treatment protocol was modified in 5/2002 now including application of 3000 IU. AT was given intravenously before pancreatic reperfusion (AT, n = 18). Patients receiving standard therapy served as controls (n = 13). Daily blood sampling was performed during five postoperative days. Standard coagulatory parameters and number of transfused red blood cell units were not altered by AT. In AT patients serum amylase (p < 0.01) and lipase (p < 0.01) on postoperative days 1, 2 and 3 were significantly reduced. Our actual perioperative management protocol including high dose AT application in human solitary pancreas transplantation reduced postoperative liberation of pancreatic enzymes in this pilot study. Prophylactic AT application should deserve further clinical testing in a randomized controlled trial.

Reperfusion pancreatitis and graft thrombosis often induce early graft loss in simultaneous pancreas-kidney (SPK) transplantation. Antithrombin (AT) is a coagulatory inhibitor with pleiotropic activities that reduces experimental ischemia/reperfusion injury. This study retrospectively analyses prophylactic high-dose AT application in patients with first SPK. In an university transplantation center, 53 consecutive patients with SPK were studied without randomization. In one group, 3000 IU of AT was given intravenously before pancreatic reperfusion (AT, n = 24). Patients receiving standard therapy including postoperative AT supplementation (controls, n = 29) served as controls. Daily blood sampling was performed as a part of the clinical routine during four postoperative days. There were no differences in demographic and laboratory parameters [donor/recipient age, ischemia time, perfusion solution, body weight, mismatches] between both groups. Baseline creatinine values were lower in the control group versus AT group (P < 0.05). Coagulatory parameters and bleeding incidence were not influenced by AT, while incidence of graft thrombosis was reduced (control: 7/29; AT: 4/24; relative reduction of risk: -33%; P < 0.05). Single-shot AT application during SPK modulated serum lipase activity on postoperative days 2 and 3, and minimized risk for graft thromboses without increasing perioperative bleeding. This new concept should deserve testing in a prospective clinical trial.
