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.

Abstract
BACKGROUND Simultaneous pancreas-kidney (SPK) transplantation carries a higher risk of surgical complications than kidney transplantation alone. We aimed to establish the incidence of surgical complications after SPK transplantation and determine the effect on graft and patient survival. METHODS Outcomes of all SPK transplants performed at our centre were compared between patients who experienced a surgical complication (SC group) and those who did not (NSC group). RESULTS Our centre performed 193 SPK transplants in a 15-year period; 44 patients (23%) experienced a surgical complication. One-year and 5-year pancreatic graft survival was 89 and 80%, respectively; this was lower in the SC group. There was no significant difference in patient or kidney graft survival between the SC and NSC groups at 5 years (92 and 83%, respectively.) CONCLUSION Surgical complications following SPK transplantation can cause significant morbidity and adversely affect pancreas graft survival, but do not affect long-term kidney or patient survival.

Abstract
The long-term normalization of glucose metabolism - a prerequisite for the prevention of secondary complications in patients with diabetes mellitus - is only possible by transplantation of a whole pancreas or a reasonable number of islets. An absolute indication for pancreas grafting is given in type 1 diabetic patients with end-stage renal disease. The 1-year survival after simultaneous kidney/pancreas transplantation is, according to the international registry, 94-100% for patients, 89-92% for kidneys and 85-87% for the pancreas. The high success rate with long lasting normalization of glucose metabolism leads to a stabilization and/or amelioration of secondary complications, to an increase in quality of life and, most importantly, to a significant reduction in mortality when compared to diabetic kidney recipients. The indications for islet transplantation are similar to those for pancreatic grafting. Islet grafting is only a minor surgical procedure, but islet isolation is difficult. The 1-year survival for the recipients is 98%, for the islets 82% and for insulin-independency 42%. There is a significant decline of islet function to 10% 5 years after transplantation. Stem cell therapy would provide a definitive treatment solution not only for patients with type 1 diabetes. So far, this therapeutic option is still at an early stage of development.

Abstract
BACKGROUND The objective of this study was to determine the long-term results after simultaneous pancreas-kidney transplantation (SPK) at a single-center institution in Europe. PATIENTS AND METHODS Seventy-eight consecutive patients with insulin-dependent diabetes mellitus and end-stage nephropathy were followed for a median of 7 years after SPK. Immunosuppressive protocol consisted of cyclosporine A, azathioprine, prednisone, and antithymocyte globulin. Multivariate Cox proportional hazard model was used to investigate the impact of different putative risk factors on long-term patient survival. Health-related quality of life was assessed by a validated questionnaire (SF-36). RESULTS Patient survival at 5 and 10 years was 81% and 67%, respectively. Pancreas function rate was 73% and 60% and kidney function 67% and 44%, respectively. In multivariate analysis, preexisting myocardial infarction (relative risk [RR] 5.1, 95% confidence interval [CI] 1.5-16.6) and amputation (RR 3.7, 95% CI 1.1-12.9) were strongly associated with a diminished long-term patient survival. Analysis of patients with long-term functioning pancreas and kidney grafts revealed excellent results for quality of life posttransplant that were comparable with average scores of the normal German population. CONCLUSIONS This series representing the largest experience with long-term follow-up in Europe confirms an excellent long-term survival and an exceptional quality of life after SPK.

Abstract
Patients with type 1 diabetes mellitus and end-stage renal disease may remain on dialysis or undergo cadaveric kidney transplantation, living kidney transplantation, sequential pancreas after living kidney transplantation, or simultaneous pancreas-kidney transplantation. It is unclear which of these options is most effective. The objective of this study was to determine the optimal treatment strategy for type 1 diabetic patients with renal failure using a decision analytic Markov model. Input data were obtained from the published medical literature, the United Network for Organ Sharing registry, and patient interviews. The outcome measures were life expectancy (in life-years [LY]) and quality-adjusted life expectancy (in quality-adjusted life-years [QALY]). Living kidney transplantation was associated with 18.30 LY and 10.29 QALY; pancreas after kidney transplantation, 17.21 LY and 10.00 QALY; simultaneous pancreas-kidney transplantation, 15.74 LY and 9.09 QALY; cadaveric kidney transplantation, 11.44 LY and 6.53 QALY; dialysis, 7.82 LY and 4.52 QALY. The results were sensitive to the value of several key variables. Simultaneous pancreas-kidney transplantation had the greatest life expectancy and quality-adjusted life expectancy when living kidney transplantation was excluded from the analysis. These data indicate that living kidney transplantation is associated with the greatest life expectancy and quality-adjusted life expectancy for type 1 diabetic patients with renal failure. Treatment strategies involving pancreas transplantation should be considered for patients with frequent metabolic complications of diabetes and for those patients who favor kidney-pancreas transplantation over kidney transplantation alone. For patients without a living donor, simultaneous pancreas-kidney transplantation is associated with the greatest life expectancy.

Abstract
Pancreas transplantation is still the best option to achieve normoglycaemia and insulin independence in patients with type I diabetes. As a result of improvements in surgical techniques, immunosuppression and patient selection, one year survival rates of 95, 83, and 88% for patient, pancreas, and kidney survival, respectively, are reported for patients with simultaneous pancreas and kidney transplantation. The main goals for the future are to reduce postoperative morbidity, to identify the relevant indications for single pancreas transplantation, to adopt the best surgical technique for individual patients' needs (bladder versus enteric drainage with or without portal venous delivery of insulin), and to develop immunosuppressive strategies with low nephrotoxic and diabetogenic potential.

Abstract
BACKGROUND Simultaneous pancreas-kidney transplantation (SPK) ameliorates the progression of microvascular diabetic complications but the procedure is associated with excess initial morbidity and an uncertain effect on patient survival when compared with solitary cadaveric or living donor renal transplantation. We evaluated mortality risks associated with SPK, solitary renal transplantation, and dialysis treatment in a national cohort of type 1 diabetics with end-stage nephropathy. METHODS A total of 13,467 adult-type 1 diabetics enrolled on the renal and renal-pancreas transplant waiting list between 10/01/88 and 06/30/97 were followed until 06/30/98. Time-dependent mortality risks and life expectancy were calculated according to the treatment received subsequent to wait-list registration: SPK; cadaveric kidney only (CAD); living donor kidney only (LKD) transplantation; and dialysis [wait-listed, maintenance dialysis treatment (WLD)]. RESULTS Adjusted 10-year patient survival was 67% for SPK vs. 65% for LKD recipients (P=0.19) and 46% for CAD recipients (P<0.001). The excess initial mortality normally associated with renal transplantation and the risk of early infectious death was 2-fold higher in SPK recipients. The time to achieve equal proportion of survivors as the WLD patients was 170, 95, and 72 days for SPK, CAD, and LKD recipients, respectively (P<0.001). However, the adjusted 5-year morality risk (RR) using WLD as the reference and the expected remaining life years were 0.40, 0.45, and 0.75 and 23.4, 20.9, and 12.6 years for SPK, LKD, and CAD, respectively. There was no survival benefit in SPK recipients > or =50 years old (RR=1.38, P=0.81). CONCLUSIONS Among patients with type 1 DM with end-stage nephropathy, SPK transplantation before the age of 50 years was associated with long-term improvement in survival compared to solitary cadaveric renal transplantation or dialysis.

Abstract
BACKGROUND Diabetic renal disease continues to be the most significant cause of end-stage renal disease (ESRD) in the United States. Renal transplantation improves diabetic ESRD patient survival; however, the diabetic state remains associated with poor patient survival. Simultaneous pancreas-kidney (SPK) transplantation can restore normoglycemia and thus may improve outcomes. METHODS We assessed the impact of SPK on age-range-matched type 1 diabetic patients who underwent renal transplantation at a single center. The observed/expected life span and annual mortality rates (AMRs) were used as measures of survival. A Cox proportional hazards analysis was used to analyze the impact of potential variables on mortality in SPK recipients. RESULTS SPK transplantation (N = 335) increased the observed/expected life span compared with diabetic cadaveric (DM-Cad, N = 147) and live-donor (DM-Live, N = 160) transplant recipients (P = 0.004) and significantly reduced the AMRs (SPK, 1. 5%; DM-Cad, 6.27%; DM-Live, 3.65%, P = 0.008, SPK vs. other DM). Moreover, the SPK observed/expected life span and AMR were not significantly different from that of age-range-matched nondiabetic transplant recipients (N = 492). The only variable that was significantly associated with patient survival was discharge serum creatinine (relative risk 1.16, P < or = 0.0154). CONCLUSION These data demonstrate that SPK improves the ability for type 1 diabetic patients to live more of their expected life span. This suggests that glycemic control, even as a late intervention in a diabetic patient's lifetime, may beneficially affect survival.

Abstract
UNLABELLED Tacrolimus (FK-506) is an immunosuppressant agent that acts by a variety of different mechanisms which include inhibition of calcineurin. It is used as a therapeutic alternative to cyclosporin, and therefore represents a cornerstone of immunosuppressive therapy in organ transplant recipients. Tacrolimus is now well established for primary immunosuppression in liver and kidney transplantation, and experience with its use in other types of solid organ transplantation, including heart, lung, pancreas and intestinal, as well as its use for the prevention of graft-versus-host disease in allogeneic bone marrow transplantation (BMT), is rapidly accumulating. Large randomised nonblind multicentre studies conducted in the US and Europe in both liver and kidney transplantation showed similar patient and graft survival rates between treatment groups (although rates were numerically higher with tacrolimus- versus cyclosporin-based immunosuppression in adults with liver transplants), and a consistent statistically significant advantage for tacrolimus with respect to acute rejection rate. Chronic rejection rates were also significantly lower with tacrolimus in a large randomised liver transplantation trial, and a trend towards a lower rate of chronic rejection was noted with tacrolimus in a large multicentre renal transplantation study. In general, a similar trend in overall efficacy has been demonstrated in a number of additional clinical trials comparing tacrolimus- with cyclosporin-based immunosuppression in various types of transplantation. One notable exception is in BMT, where a large randomised trial showed significantly better 2-year patient survival with cyclosporin over tacrolimus, which was primarily attributed to patients with advanced haematological malignancies at the time of (matched sibling donor) BMT. These survival results in BMT require further elucidation. Tacrolimus has also demonstrated efficacy in various types of transplantation as rescue therapy in patients who experience persistent acute rejection (or significant adverse effect's) with cyclosporin-based therapy, whereas cyclosporin has not demonstrated a similar capacity to reverse refractory acute rejection. A corticosteroid-sparing effect has been demonstrated in several studies with tacrolimus, which may be a particularly useful consideration in children receiving transplants. The differences in the tolerability profiles of tacrolimus and cyclosporin may well be an influential factor in selecting the optimal treatment for patients undergoing organ transplantation. Although both drugs have a similar degree of nephrotoxicity, cyclosporin has a higher incidence of significant hypertension, hypercholesterolaemia, hirsutism and gingival hyperplasia, while tacrolimus has a higher incidence of diabetes mellitus, some types of neurotoxicity (e.g. tremor, paraesthesia), diarrhoea and alopecia. CONCLUSION Tacrolimus is an important therapeutic option for the optimal individualisation of immunosuppressive therapy in transplant recipients.

Abstract
Although intensified insulin therapy regimens enable normalization of blood glucose levels and related metabolic parameters, these regimens are associated with an increased incidence of hypoglycemic episodes. Pancreas transplantation has achieved the goal of providing insulin independence with stable and continuous normoglycemia. But because of the associated morbidity and mortality and the need for life-long immunosuppression after transplant, it is difficult to justify pancreas transplantation in diabetic patients at a pre-uremic stage. Pancreas transplantation is therefore performed in conjugation with renal transplantation. The majority of renal transplant centers, however, have been reluctant to perform simultaneous kidney-pancreas transplantation in insulin-dependent uremic patients because of the additional risks associated with pancreas transplantation. More recently, refinements in surgical technique, introduction of new immunosuppressive agents, and better selection of transplant candidates have contributed to improved survival. Today, combined pancreas-kidney transplantation is an accepted treatment for carefully selected patients with insulin dependent diabetes and end-stage renal disease and in a small group of patients with uncontrolled severe metabolic problems. The effect of a euglycemic state after pancreas transplantation on the progression of micro- and macroangiopathy remains to be proved, although recently there is evidence to suggest that some end-organ lesions may be halted or even ameliorated. Further improvement in anti-rejection strategies may achieve better long-term graft survival and provide the incentive to perform pancreas transplantation at an earlier stage, before severe secondary complications of diabetes develop.
