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
More than 2 million people in the United States have type 1 diabetes mellitus. Pancreatic transplantation has emerged as the single most effective means of achieving normal glucose homeostasis in this patient population. Newer immunosuppressive agents and surgical techniques continue to evolve, resulting in improved long-term graft and patient survival. Herein, an understanding of the evaluation, technical aspects, and perioperative management of pancreas transplantation is outlined.

Abstract
BACKGROUND Compared with the impact of delayed graft function (DGF) after renal transplantation, DGF after pancreas transplantation has not been fully evaluated. METHODS We retrospectively verified the impact of DGF on long-term pancreas graft survival in surgically successful cases. Pancreas graft failure was defined by the recipient's return to exogenous insulin administration. RESULTS Between May 2004 and April 2013, we performed 135 technically successful primary pancreas transplantations. Delayed graft function was defined as a total cumulative insulin requirement of 19 UI or greater within postoperative 7 days. Of the 135 recipients in our study cohort, 47 (34.8%) developed DGF after the pancreas transplantation. By multivariate analysis, DGF was found to be associated with a donor age of 30 years or older (odds ratio, 3.4; 95% confidence interval, 1.50-7.69; P=0.003) and the increased ratio of body mass index in a recipient to a donor (odds ratio, 26.1; 95% confidence interval, 2.53-270.0; P=0.006). There was a trend toward higher acute rejection (P=0.622) and mortality (P=0.49) rates in recipients with versus without DGF, although this did not reach statistical significance. Delayed graft function was found to be associated with a greater risk of overall pancreas graft failure (P=0.016) and death-censored graft failure (P=0.037). CONCLUSION Delayed graft function after pancreas transplantation was found to be associated with a greater risk of overall pancreas graft failure and death-censored graft failure.

Abstract
BACKGROUND Pancreas or kidney-pancreas transplantation improves survival and quality of life for people with type 1 diabetes mellitus and kidney failure. Immunosuppression after transplantation is associated with complications. Steroids have adverse effects on cardiovascular risk factors such as hypertension, hyperglycaemia or hyperlipidaemia, increase risk of infection, obesity, cataracts, myopathy, bone metabolism alterations, dermatologic problems and cushingoid appearance. Whether avoiding steroids changes outcomes is unclear. OBJECTIVES We aimed to assess the safety and efficacy of steroid early withdrawal (treatment for less than 14 days after transplantation), late withdrawal (after 14 days after transplantation) or steroid avoidance in patients receiving a pancreas (including a vascularized organ) alone (PTA), simultaneous with a kidney (SPK) or after kidney transplantation (PAK). SEARCH METHODS We searched the Cochrane Renal Group's Specialised Register (to 18 June 2014) through contact with the Trials' Search Co-ordinator. We handsearched: reference lists of nephrology textbooks, relevant studies, recent publications and clinical practice guidelines; abstracts from international transplantation society scientific meetings; and sent emails and letters seeking information about unpublished or incomplete studies to known investigators. SELECTION CRITERIA We included randomised controlled trials (RCTs) or cohort studies of steroid avoidance (including early withdrawal) versus steroid maintenance or versus late withdrawal in pancreas or pancreas with kidney transplant recipients. We defined steroid avoidance as complete avoidance of steroid immunosuppression, early steroid withdrawal as steroid treatment for less than 14 days after transplantation and late withdrawal as steroid withdrawal after 14 days after transplantation. DATA COLLECTION AND ANALYSIS Two authors independently assessed the retrieved titles and abstracts, and where necessary the full text reports to determine which studies satisfied the inclusion criteria. Authors of included studies were contacted to obtain missing information. Statistical analyses were performed using random effects models and results expressed as risk ratio (RR) or mean difference (MD) with 95% confidence interval (CI). Cohort studies were not meta-analysed, but their findings summarised descriptively. MAIN RESULTS Three RCTs enrolling 144 participants met our inclusion criteria. Two compared steroid avoidance versus late steroid withdrawal and one compared late steroid withdrawal versus steroid maintenance. All studies included SPK and only one also included PTA. All studies had an overall moderate risk of bias and presented only short-term results (six to 12 months). Two studies (89 participants) compared steroid avoidance or early steroid withdrawal versus late steroid withdrawal. There was no clear evidence of an impact on mortality (2 studies, 89 participants: RR 1.64, 95% CI 0.21 to 12.75), risk of kidney loss censored for death (2 studies, 89 participants: RR 0.35, 95% CI 0.04 to 3.09), risk of pancreas loss censored for death (2 studies, 89 participants: RR 1.05, 95% CI 0.36 to 3.04), or acute kidney rejection (1 study, 49 participants: RR 2.08, 95% CI 0.20 to 21.50), however results were uncertain and consistent with no difference or important benefit or harm of steroid avoidance/early steroid withdrawal. The study that compared late steroid withdrawal versus steroid maintenance observed no deaths, no graft loss or acute kidney rejection at six months in either group and reported uncertain effects on acute pancreas rejection (RR 0.88, 95% CI 0.06 to 13.35). Of the possible adverse effects only infection was reported by one study. There were significantly more UTIs reported in the late withdrawal group compared to the steroid avoidance group (1 study, 25 patients: RR 0.41, 95% CI 0.26 to 0.66).We also identified 13 cohort studies and one RCT which randomised tacrolimus versus cyclosporin. These studies in general showed that steroid-sparing and withdrawal strategies had benefits in lowering HbAc1 and risk of infections (BK virus and CMV disease) and improved blood pressure control without increasing the risk of rejection. However, two studies found an increased incidence of acute pancreas rejection (HR 2.8, 95% CI 0.89 to 8.81, P = 0.066 in one study and 43.3% in the steroid withdrawal group versus 9.3% in the steroid maintenance, P < 0.05 at three years in the other) and one study found an increased incidence of acute kidney rejection (18.7% in the steroid withdrawal group versus 2.8% in the steroid maintenance, P < 0.05) at three years. AUTHORS' CONCLUSIONS There is currently insufficient evidence for the benefits and harms of steroid withdrawal in pancreas transplantation in the three RCTs (144 patients) identified. The results showed uncertain results for short-term risk of rejection, mortality, or graft survival in steroid-sparing strategies in a very small number of patients over a short period of follow-up. Overall the data was sparse, so no firm conclusions are possible. Moreover, the 13 observational studies findings generally concur with the evidence found in the RCTs.

Abstract
For reducing the corticosteroid (CS)-related side-effects, especially cardiovascular events, CS-sparing protocols have become increasingly common in pancreas transplantation (PT). Lympho-depleting induction antibodies, such as rabbit anti-thymocyte globulin (rATG) or alemtuzumab, have been widely used in successful trials. The results of various CS-sparing protocols combining calcineurin inhibitors (CNI) and mycophenolate or sirolimus, have been mixed for rejection and survival rates. Most of the studies were uncontrolled trials of low-risk patients, therefore the grade of evidence is limited. Large-scale prospective studies with long-term follow up are necessary to assess risks and benefits of CS-sparing regimens in PT before recommending such strategies as standard practice. Islet allo-transplantation for patients with brittle type 1 diabetes mellitus, less invasive and safer procedure than PT, has been attempted since late 1980s, but diabetogenic immunosuppressants at maintenance, mainly CS and high-dose CNI, prevented satisfactory results (10% insulin-independence at 1-year post-transplant). Since 2000, CS-free and CNI-reducing protocols, including more potent induction [daclizumab, OKT3gamma1(ala-ala) anti-CD3 antibody, rATG] and maintenance (sirolimus, mycophenolate) agents, have significantly improved short-term outcomes whereas long-term are still inadequate (from 80% to 20% insulin-independence from 1- to 5-year post-transplant). Main limitations are allo- and autoimmunity, immunosuppression-related islet and systemic toxicity and transplant site unsuitability, which tolerogenic protocols and biotechnological solutions may solve.

Abstract
Simultaneous pancreas-kidney (SPK) transplantation is a promising treatment option for patients with type 1 diabetes and end-stage renal disease. Most of these patients can achieve normalization of glucose and hemoglobin A(1c) levels. Patient and graft survival continues to improve; however, defects in beta-cell function and insulin resistance can be seen over time after transplant. Various methods can be used to assess the SPK recipient for the development of hyperglycemia and graft dysfunction, with treatment aimed at minimizing diabetogenic immunosuppression, using agents that may preserve beta-cell function, and improving insulin resistance.

Abstract
Of 25 simultaneous pancreas-kidney transplant (SPK) recipients treated with thymoglobulin induction, sirolimus and reduced-dose cyclosporine (CsA), 18 low-immune responders (non-African-Americans, PRA < 30%) were withdrawn from prednisone on post-transplant day 5, whereas seven high-immune responders continued on prednisone. Most high- and low-immune responder recipients were converted from CsA to mycophenolic acid (MPA) at six months post-transplantation. At a mean follow-up of 28 +/- 10 months, two pancreas grafts were lost to pancreatitis. There were no patient or kidney graft losses, but one acute rejection episode. At 28 +/- 11 months, all 18 low-responder recipients remain steroid-free. Twenty recipients (14 low and six high-immune responders) were converted from CsA to MPA. During conversion, immune response was monitored by Flow-PRA and T-cell stimulation (Cylex) assays. Nineteen of 20 recipients displayed a post-conversion PRA of 0%, whereas one highly sensitized patient expressed a post-conversion PRA of 67%. Fifty-eight percent of individual T-cell stimulation scores were in the hypo-responsive range. Twelve of 18 low-immune responders are both steroid and CsA-free at a mean follow-up of 17 +/- 13 months, whereas five of seven high-immune responders remain CsA-free at a mean follow-up of 11 +/- 10 months. These data suggest that thymoglobulin induction with combined sirolimus and CsA maintenance therapy permits immunosuppression minimization in selected SPK recipients.

Abstract
BACKGROUND Steroid-free immunosuppression is an attractive option because it avoids the many side effects of chronic corticosteroid use. It is especially attractive in pancreas recipients because it avoids the diabetogenic effects of steroids. METHODS We evaluated the outcome of a steroid-free maintenance immunosuppressive protocol in pancreas transplant recipients. Between August 2003 and May 2006, a total of 97 pancreas transplant recipients received steroid-free maintenance immunosuppression, consisting of induction with thymoglobulin and prednisone for the first 5 days. Patients were maintained on sirolimus adjusted to a target rapamycin trough level and reduced-dose cyclosporine adjusted to target C2 levels. All pancreas transplants (n=124) performed in the previous 3 years and maintained on a steroid-based immunosuppressive protocol with cyclosporine and mycophenolate mofetil were used for comparison. RESULTS One-year patient and death censored pancreas graft survival were 93.8% and 94.8% for the steroid free group versus 95.2% and 87.9% for the comparator group, respectively. The incidence of acute rejection was 9.3% in the steroid-free group versus 28.3% in the comparator group (P<0.01). No pancreas loss in the steroid-free group was caused by acute rejection, whereas seven (5.6%) patients in the comparator group lost their pancreases because of acute rejection (P<0.05). At 1 year after transplant, the mean serum glucose and creatinine levels were not different between the two groups. CONCLUSION We conclude that excellent graft survival with a significantly lower incidence of acute rejection can be achieved using a steroid-free maintenance immunosuppressive protocol consisting of sirolimus and cyclosporine.

Abstract
Although steroid withdrawal in simultaneous kidney pancreas transplantation has been shown to be feasible, the results of early steroid withdrawal in immunologically solitary pancreas transplantation are not well known. This study evaluated an early steroid withdrawal protocol in this group. The results of steroid withdrawal at 21 d post-transplant in solitary pancreas transplant recipients was compared with a control group consisting of solitary pancreas transplant recipients maintained on steroids (MG). Additional immunosuppression consisted of rabbit anti-thymocyte globulin induction followed by tacrolimus and mycophenolate mofetil in both groups. The withdrawal group (WG, n = 22) consisted of 11 pancreas transplant alone (PTA), six pancreas after kidney (PAK), and five simultaneous cadaveric pancreas living kidney (SPLK) recipients. The steroid maintenance group (MG, n = 32) consisted of 8 PTA, 11 PAK, and 13 SPLK recipients. Recipient and donor demographic characteristics were similar. Seventy eight percent of MG patients had infection-related complications in the first year compared with 50% of the WG patients (p = 0.04). The one-yr rejection, pancreas graft, and patient survival rates were 27.3% 95.5%, and 100% in the WG, and 37.5%, 81.3%, and 93.8% in the MG respectively and not significantly different. We conclude that early corticosteroid withdrawal in isolated pancreas transplantation results in fewer infections and can be achieved without an increased risk of rejection or graft loss over the first year.

Abstract
UNLABELLED Corticosteroids are an important element of immunosuppressive protocols, but their long-term use has detrimental effects on patient health, requiring eventual discontinuation. Herein, we present an evaluation of the safety and feasibility of corticosteroid withdrawal based on the findings of the Euro-SPK001 study. PATIENTS AND METHODS In this prospective, multicenter study, 205 simultaneous pancreas-kidney (SPK) transplant recipients were randomized to immunosuppressive treatment with either tacrolimus and mycophenolate mofetil (MMF) (n = 103) or cyclosporine microemulsion (CsA-ME) and MMF (n = 102). All patients received concomitant rATG induction therapy, MMF, and short-term corticosteroids. RESULTS Corticosteroid withdrawal was successful in the majority of in-study patients: 66% tacrolimus and 73% cyclosporin-ME. In-study patients selected for corticosteroid withdrawal experienced fewer pancreatic or kidney graft losses and fewer episodes of acute rejection compared with out-of-study patients or those continuing corticosteroid therapy. Acute rejection episodes occurred after corticosteroid withdrawal in two patients who had a previous rejection and in five patients who were rejection free before corticosteroid withdrawal. No rejection episodes were associated with graft loss or immediate serious consequences. Overall, corticosteroid withdrawal was achieved with an increase in both MMF and tacrolimus dosage. CONCLUSION Corticosteroid withdrawal was successful in the majority of in-study patients. A long-term survey of corticosteroid withdrawal in SPK transplantation with multifactorial analyses is necessary to confirm these early results and to evaluate possible positive effects on glucose metabolism and hypertension.

Abstract
BACKGROUND New immunosuppressive protocols and advanced surgical techniques have brought major improvements in pancreas transplantation outcomes. Steroid withdrawal might have a beneficial long-term effect on metabolic parameters. METHODS We retrospectively analyzed 112 enteric-drained pancreas transplants (PTx) performed between March 1997 and October 2001. Prophylactic imunosuppression consisted of ATG induction, tacrolimus, MMF, and steroids. RESULTS Actuarial patient, pancreas, and kidney graft survivals at 1 year were 96.4%, 86.7%, and 95.3%, respectively. The 5-year pancreatic graft survival was 77%. In addition to four patients who died with functioning grafts, eight grafts were lost due to intraabdominal infection; ten due to rejection; and the remaining three, due to other complications. One-year follow-up was available for 89 patients, Including 22 (25%) withdrawn from steroids. Significantly lower median serum cholesterol values were measured among patients off steroids (158 mg/dL [range 135 to 231 mg/dL] versus 188 mg/dL [range 91 to 278 mg/dl]; P = .005). In contrast, the difference in triglycerides did not reach statistical significance; that is, at last follow-up, at a median of 41.3 months posttransplant, 64 patients (70% of the available study population) were off steroids. Cessation of steroids resulted in significantly lower cholesterol (median 176 mg/dL [range 101 to 229 mg/dL] versus 196 mg/dL [range 107 to 339 mg/dL]; P = .047) and triglyceride values (median 74 mg/dL [range 34 to 299 mg/dL] versus 98 mg/dL [range 47 to 565 mg/dL]; P = .008), but had no impact on rejection rate, serum creatinine and urea, HbA(1c), or fasting blood glucose levels. CONCLUSIONS Steroid withdrawal after pancreatic transplantation can be performed in the majority of cases without risking an immunologic complication, but it seems to be associated also with the benefit of improved lipid metabolism.

Abstract
Pancreas transplant has become a reliably predictable treatment and cure for patients with type 1 diabetes mellitus and hypoglycemic unawareness or renal failure. During the past 2 years, the use of enteric drainage has been shown to decrease morbidity over traditional bladder drainage, and the use of the portal system for venous drainage continues to be explored. Technically, the use of circular staplers, over a hand-sown anastomosis for duodenal drainage, has gained popularity, and alternative arterial reconstruction methods have been developed. Living donor pancreas and kidney transplants are also becoming more common throughout the world. In the area of immunosuppression, steroid-free protocols, now commonplace in kidney transplants, are being applied successfully to pancreas transplantation. Finally, the benefit of solitary pancreas and pancreas after kidney transplantation has been questioned, and a more complete analysis of pancreas alone and pancreas after kidney transplants is anticipated in the near future.

Abstract
We report on the feasibility of a glucocorticoid-free immunosuppression (sirolimus, low-dose tacrolimus, and daclizumab) in simultaneous islet-kidney transplantation in nine patients with type 1 diabetes. There was one renal primary nonfunction. Renal function (n = 8) as assessed by creatinine and creatinine clearance over time was 103 +/- 6 micromol/L and 64 +/- 6 mL/min/1.73 m(2), respectively. Five out of six patients with >or= 2 islet transplantations became insulin independent. The mean HbA(1c) during the follow-up period for all patients after transplantation is 6.2 +/- 0.9% as compared with 8.7 +/- 1.9% prior to transplant. These results in patients with a median follow-up of 2.3 years suggest that kidney transplantation under a glucocorticoid-free immunosuppression is feasible, and that the rate of insulin independence of 80% can be achieved not only in patients with no or minimal diabetes complications, but also in patients with more advanced late complications and in conjunction with kidney transplantation.

Abstract
BACKGROUND After pancreas transplantation, endocrine function is determined by the insulin secretory capacity of the transplanted pancreas. The authors evaluated the predictive value of postoperative oral glucose tolerance test (OGTT) and stimulated insulin secretion on long-term endocrine function. METHODS Forty-one patients after pancreas-kidney transplantation with systemic venous drainage were studied. Patients were categorized to have normal glucose tolerance (NGT) or impaired glucose tolerance (IGT) (World Health Organization criteria: NGT, <7.8 mM; IGT, 7.8-11.1 mM 120 min after glucose intake) and high or low total insulin secretion. Mean follow-up of graft function and patient outcome was 10.2+/-0.5 years after OGTT. RESULTS Patients with IGT had grafts with a longer ischemia time and a significantly worse urine amylase excretion as compared with patients with NGT. Using Kaplan-Meier survival analysis, patients with NGT had better long-term pancreatic function as compared with IGT in the follow-up after performing the first OGTT (mean, 10.9+/-0.2 vs. 8.8+/-0.9 years of graft function; P=0.02), but there was no difference in patient survival and kidney graft function. Also, high insulin secretion predicted significantly longer pancreas graft function as compared with low insulin secretion (P=0.04). CONCLUSIONS Although IGT does not lead to poorer long-term patient survival and kidney graft function, it does predict compromised long-term endocrine function of the transplanted pancreas. Therefore, postoperative OGTT are useful tools for identification of patients at risk of long-term endocrine graft failure after pancreas transplantation.
