Assessing the influence of graft loss on 4-year patient survival after simultaneous pancreas-kidney transplantation: Kaplan-Meier versus Competing Risk Analysis model. Clin Transplant 2024; 38:e15298. [PMID: 38545918 DOI: 10.1111/ctr.15298] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 02/28/2024] [Accepted: 03/11/2024] [Indexed: 04/20/2024]
Abstract
BACKGROUND Graft loss increases the risk of patient death after simultaneous pancreas-kidney (SPK) transplantation. The relative risk of each graft failure is complex due to the influence of several competing events. METHODS This retrospective, single-center study compared 4-year patient survival according to the graft status using Kaplan-Meier (KM) and Competing Risk Analysis (CRA). Patient survival was also assessed according to five eras (Era 1: 2001-2003; Era 2: 2004-2006; Era 3: 2007-2009; Era 4: 2010-2012; Era 5: 2012-2015). RESULTS Between 2000 and 2015, 432 SPK transplants were performed. Using KM, patient survival was 86.5% for patients without graft loss (n = 333), 93.4% for patients with pancreas graft loss (n = 46), 43.7% for patients with kidney graft loss (n = 16), and 25.4% for patients with pancreas and kidney graft loss (n = 37). Patient survival was underestimated using KM versus CRA methods in patients with pancreas and kidney graft losses (25.4% vs. 36.2%), respectively. Induction with lymphocyte depleting antibodies was associated with 81% reduced risk (HR.19, 95% CI.38-.98, p = .0048), while delayed kidney function (HR 2.94, 95% CI 1.09-7.95, p = .033) and surgical complications (HR 2.94, 95% CI 1.22-7.08, p = .016) were associated with higher risk of death. Four-year patient survival increased from Era 1 to Era 5 (79% vs. 87.9%, p = .047). CONCLUSION In this cohort of patients, kidney graft loss, with or without pancreas graft loss, was associated with higher mortality after SPK transplantation. Compared to CRA, the KM model underestimated survival only among patients with pancreas and kidney graft losses. Patient survival increased over time.

Abstract
Pancreas transplants from expanded criteria donors are performed widely in Japan because there is a shortage of brain-dead donors. However, the effectiveness of this strategy is unknown. We retrospectively studied 371 pancreas transplants to evaluate the possibility of pancreas transplantation from expanded criteria donors by the Pancreas Donor Risk Index (PDRI). Patients were divided into five groups according to quintiles of PDRI values (Q1-Q5). The 1-year pancreas graft survival rates were 94.5% for Q1, 91.9% for Q2, 90.5% for Q3, 89.3% for Q4, and 79.6% for Q5, and were significantly lower with a lower PDRI (p = 0.04). A multivariate analysis showed that the PDRI, donor hemoglobin A1c values, and pancreas transplantation alone significantly predicted 1-year pancreas graft survival (all p < 0.05). Spline curve analysis showed that the PDRI was incrementally associated with an increased risk of 1-year graft failure. In the group with a PDRI ≥ 2.87, 8/56 patients had graft failures within 1 month, and all were due to graft thrombosis. The PDRI is a prognostic factor related to the 1-year graft survival rate. However, pancreas transplantation from high-PDRI donors shows acceptable results and could be an alternative when the donor pool is insufficient.

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 The impact of pancreas transplantation, including kidney transplantation on patients' life prognoses, is unclear in Japan. An analysis of the data of the Japan Pancreas Transplant Registry was performed to compare the patient survival between on the waiting list and after pancreas transplantation, and investigate the factors that affect the patient survival after pancreatic transplantation. METHODS The life prognoses of 361 patients who underwent pancreas transplantation from 2000 to December 2018 were examined. RESULTS The survival rates at 1, 5, and 10 years on the waiting list were 98.4%, 90.3%, and 78.1%, respectively, while those after transplantation were significantly improved (p = 0.029) at 100%, 97.5%, and 88.9%, respectively. Furthermore, the survival rates of patients waiting for simultaneous pancreas and kidney transplantation (SPK) at 1, 5, and 10 years were 98.2%, 89.4%, and 75.4%, respectively, while those after SPK were also significantly improved (p = 0.026) at 100%, 94.6%, and 88.8%. The multivariable analysis revealed that the duration of diabetes before surgery was the only independent risk factor (hazard ratio = 1.095, p = 0.012) that affected the patient survival after SPK. CONCLUSION Pancreas transplantation was found to improve the life prognosis of patients with type 1 diabetes, especially those with end-stage renal failure waiting for SPK.

Abstract
OBJECTIVE In patients with type 1 diabetes and end-stage renal disease, it is controversial whether a simultaneous pancreas-kidney (SPK) transplantation improves survival compared with kidney transplantation alone. We compared long-term survival in SPK and living- or deceased-donor kidney transplant recipients. RESEARCH DESIGN AND METHODS We included all 2,796 patients with type 1 diabetes in the Netherlands who started renal replacement therapy between 1986 and 2016. We used multivariable Cox regression analyses adjusted for recipient age and sex, dialysis modality and vintage, transplantation era, and donor age to compare all-cause mortality between deceased- or living-donor kidney and SPK transplant recipients. Separately, we analyzed mortality between regions where SPK transplant was the preferred intervention (80% SPK) versus regions where a kidney transplant alone was favored (30% SPK). RESULTS Of 996 transplanted patients, 42%, 16%, and 42% received a deceased- or living-donor kidney or SPK transplant, respectively. Mean (SD) age at transplantation was 50 (11), 48 (11), and 42 (8) years, respectively. Median (95% CI) survival time was 7.3 (6.2; 8.3), 10.5 (7.2; 13.7), and 16.5 (15.1; 17.9) years, respectively. SPK recipients with a functioning pancreas graft at 1 year (91%) had the highest survival (median 17.4 years). Compared with deceased-donor kidney transplant recipients, adjusted hazard ratios (95% CI) for 10- and 20-year all-cause mortality were 0.79 (0.49; 1.29) and 0.98 (0.69; 1.39) for living-donor kidney and 0.67 (0.46; 0.98) and 0.79 (0.60; 1.05) for SPK recipients, respectively. A treatment strategy favoring SPK over kidney transplantation alone showed 10- and 20-year mortality hazard ratios of 0.56 (0.40; 0.78) and 0.69 (0.52; 0.90), respectively. CONCLUSIONS Compared with living- or deceased-donor kidney transplantation, SPK transplant was associated with improved patient survival, especially in recipients with a long-term functioning pancreatic graft, and resulted in an almost twofold lower 10-year mortality rate.

Abstract
Pancreas transplant has evolved significantly in recent years. It has now become a viable treatment option on type 1 diabetic patients with poorly controlled diabetes on conventional treatment, insulin intolerance, hypoglycaemia unawareness, brittle diabetes and/ or end-stage kidney disease. The purpose of this review is to provide an overview of pancreas transplant historical origins and current barriers to broader utilization of pancreata for transplant, with a focus on areas for future improvement to better pancreas transplant care. Donor pancreata remain underutilized; pancreatic allograft discard rates remain close to 30% in the United States. Donations after cardiac death (DCD) pancreata are seldom procured. Study groups from Europe and the United Kingdom showed that procurement professionalization and standardization of technique, as well as development of independent regional procurement teams might increase organ procurement efficiency, decrease discards and increase pancreatic allograft utilization. Pancreas transplant programs should consider exploring pancreas procurement opportunities on DCD and obese donors. Selected type 2 diabetics should be considered for pancreas transplant. Longer follow-up studies need to be performed in order to ascertain the long-term cardiovascular and quality of life benefits following pancreas transplant; the outcomes of which might eventually spearhead advocacy towards broader application of pancreas transplant among diabetics.

Abstract
PURPOSE To evaluate the effect of mycophenolate (mycophenolic acid, MPA) dose on pancreas allograft survival following simultaneous pancreas kidney (SPK) transplant. METHODS This was an observational study of adult SPK recipients transplanted between 1/1/2002 and 6/30/2015. Recipients were divided into cohorts based on MPA dose at discharge: high dose (HD), 1000 mg three times daily mycophenolate mofetil (MMF) and standard dose (SD), 1000 mg twice daily MMF. Primary outcome was pancreas allograft survival. Secondary endpoints included kidney allograft survival, pancreas allograft rejection, infection, time to initial dose decrease, and patient survival (PS). RESULTS In all, 453 patients met inclusion criteria: 324 in HD-MPA group and 129 in SD-MPA group. HD-MPA patients had higher rates of pancreas graft survival (P = .003). There were no differences in rates of pancreas allograft rejection (P = .8), kidney graft survival (P = .15), overall infection (P = .4), overall malignancy (P = .93), time to first dose reduction (P = .35), or patient survival (P = .3). In a multivariable analysis adjusted for differences between groups and known confounders, dosing group continued to significantly affect incidence of pancreas allograft failure (P = .02). CONCLUSIONS HD-MPA significantly impacted pancreas allograft survival in SPK recipients independent of graft rejection. Further studies are warranted to investigate the etiology of this finding and determine the optimal duration of HD-MPA associated with positive graft outcomes.

Abstract
BACKGROUND Our center has used a strategy of pancreas importation owing to long regional waitlist times. Here we assess the clinical outcomes and financial considerations of this strategy. METHODS This was a retrospective observational cohort study of patients who received a pancreas transplant at Montefiore Medical Center (MMC) from 2014 to 2017 (n = 28). Clinical parameters, including hemoglobin A1c and complications, were analyzed. The cohort was compared with United Network for Organ Sharing (UNOS) Region 9 with the use of the UNOS/Organ Procurement and Transplantation Network database. Cost analysis of length of stay (LOS), standard acquisition (SAC) fees, and transportation was performed with the use of internal financial data. RESULTS Pancreas importation resulted in significantly shorter simultaneous pancreas kidney transplant waitlist times compared with Region 9: 518 days vs 1001 days (P = .038). In addition, postoperative complications and 1-year HbA1c did not differ between groups: local 6.30% vs import 6.17% (P = .87). Patients receiving local pancreata stayed an average of 9.2 days compared with 11 days for the import group (P = .36). As such, pancreas importation was associated with higher mean charges ($445,968) compared with local pancreas recipients ($325,470). CONCLUSIONS Long waitlist times in Region 9 have encouraged our center's adoption of pancreas importation to address the needs of our patient population. This practice has resulted in a reduction of waitlist times by an average of 483 days. Understandably, centers have long been wary of importation owing to perceived risk in clinical outcomes. In our single-center experience, we have demonstrated equivalent postoperative glucose control and graft survival. Importantly, there does appear to be increased costs associated with importation, which are mainly driven by LOS. Curiously, importation from regions with lower SAC fees has the potential to offset costs related to transportation expenses. Notwithstanding these findings, pancreas importation does have the potential to lessen the financial societal burden through reduction in waitlist times.

Abstract
The potential to reverse diabetes has to be balanced against the morbidity of long-term immunosuppression associated with transplantation. For a patient with renal failure, the treatment of choice is often a simultaneous transplant of the pancreas and kidney or pancreas after kidney. For a patient with glycaemic instability, choices between a solid organ or islet transplant have to be weighed against benefits and risks of remaining on insulin. Results of simultaneous transplant of the pancreas and kidney transplantation are comparable to other solid-organ transplants, and there is evidence of improved quality of life and life expectancy. There is some evidence of benefit with respect to the progression of secondary diabetic complications in patients with functioning transplants for several years.

Abstract
Diabetes is the pandemic disease of the modern era, with 10% of these patients having type 1 diabetes mellitus. Despite the prevalence, morbidities, and associated financial burden, treatment options have not changed since the introduction of injectable insulin. To date, over 40,000 pancreas transplants have been performed globally. It remains the only known method for restoring glycemic control and thus curing type 1 diabetes mellitus. The aim of this review is to bring pancreatic transplantation out of the specialist realm, informing practitioners about this important procedure, so that they feel better equipped to refer suitable patients for transplantation and manage, counsel, and support when encountering them within their own specialty. This study was a narrative review conducted in October 2015, with OVID interface searching EMBASE and MEDLINE databases, using Timeframe: Inception to October 2015. Articles were assessed for clinical relevance and most up-to-date content, with articles written in English as the only inclusion criterion. Other sources used included conference proceedings/presentations and unpublished data from our institution (Oxford Transplant Centre). Pancreatic transplantation is growing and has quickly become the gold standard of care for patients with type 1 diabetes mellitus and renal failure. Significant improvements in quality of life and life expectancy make pancreatic transplant a viable and economically feasible intervention. It remains the most effective method of establishing and maintaining euglycemia, halting and potentially reversing complications associated with diabetes.

Abstract
AIMS/HYPOTHESIS Mortality due to cardiovascular disease (CVD), particularly coronary artery disease (CAD), is high in type 1 diabetic patients with end-stage renal disease (ESRD). We aimed to determine whether normoglycaemia, as achieved by successful simultaneous pancreas and kidney (SPK) transplantation, could improve long-term outcomes compared with living donor kidney-alone (LDK) transplantation. METHODS We studied 486 type 1 diabetic patients with ESRD who underwent a first SPK (n = 256) or LDK (n = 230) transplant between 1983 and 2012 and were followed to the end of 2014. Data were retrieved from the Norwegian Renal Registry and hospital records. Kaplan-Meier plots and multivariate Cox regression, with correction for recipient, donor and transplant factors, were used to examine potential associations between transplant type and all-cause and CVD- and CAD-related mortality. RESULTS Median follow-up time was 7.9 years (interquartile range 4.3, 12.9). The adjusted HR for CVD-related deaths in SPK recipients compared with LDK recipients was 0.63 (95% CI 0.40, 0.99; p = 0.047), while the HRs for all-cause and CAD-related mortality were 0.81 (95% CI 0.57, 1.16; p = 0.25) and 0.63 (95% CI 0.36, 1.12; p = 0.12), respectively. Compared with the LDK group, SPK recipients were younger and received grafts from younger donors. Cardiovascular mortality was higher in patients transplanted between 1983 and 1999 compared with those who received their grafts in subsequent years. CONCLUSIONS/INTERPRETATION In patients with type 1 diabetes and ESRD, SPK transplantation was associated with reduced long-term cardiovascular mortality compared with LDK transplantation.

Abstract
BACKGROUND The best therapeutic option for diabetic end-stage renal disease (DMESRD) has not been established among living donor kidney transplantation (LDKT), deceased donor kidney transplantation (DDKT), simultaneous pancreas and kidney transplantation (SPK), and dialysis. METHODS We retrospectively analyzed the outcomes of DMESRD patients at two Korean centers from February 2000 to December 2011. RESULTS Among 674 patients, 295 underwent kidney transplantation (LDKT, 175; DDKT, 72; and SPK, 48), while 379 were still on dialysis. The dialysis group had a higher mortality rate than the transplantation group. From the time after dialysis initiation, LDKT group had a better patient survival rate than DDKT registration group and SPK registration group. From the time after transplantation, LDKT had a better patient survival rate than DDKT; however, there was no significant difference between LDKT and SPK. In SPK, patient survival and kidney or pancreas graft survival rates were not different between types 1 and 2 DMESRD. CONCLUSION LDKT is better than waiting for SPK/DDKT in DMESRD patients, if a living donor is available, and this conclusion may be unique to Korea where waiting time for SPK is long. SPK can be used in non-obese Asians with type 2 as well as type 1 DMESRD.

Abstract
The field of pancreas transplantation has evolved from an experimental procedure in the 1980s to become a routine transplant in the modern era. With short- and long-term outcomes continuing to improve and the significant mortality, quality-of-life, and end-organ disease benefits, pancreas transplantation should be offered to more patients. In this article, we review current indications, patient selection, surgical considerations, complications, and outcomes in the modern era of pancreas transplantation.

Abstract
Diabetes mellitus is one of the most important causes of chronic kidney disease (CKD). In patients with advanced diabetic kidney disease, kidney transplantation (KT) with or without a pancreas transplant is the treatment of choice. We aimed to review current data regarding kidney and pancreas transplant options in patients with both type 1 and 2 diabetes and the outcomes of different treatment modalities. In general, pancreas transplantation is associated with long-term survival advantages despite an increased short-term morbidity and mortality risk. This applies to simultaneous pancreas kidney transplantation or pancreas after KT compared to KT alone (either living donor or deceased). Other factors as living donor availability, comorbidities, and expected waiting time have to be considered whens electing one transplant modality, rather than a clear benefit in survival of one strategy vs. others. In selected type 2 diabetic patients, data support cautious utilization of simultaneous pancreas kidney transplantation when a living kidney donor is not an option. Pancreas and kidney transplantation seems to be the treatment of choice for most type 1 diabetic and selected type 2 diabetic patients.

Abstract
AIMS/HYPOTHESIS In patients with type 1 diabetes and end-stage renal disease (ESRD) we aimed to determine whether long-term normoglycaemia, as achieved by successful simultaneous pancreas and kidney (SPK) transplantation, would preserve kidney graft structure and function better than live donor kidney (LDK) transplantation alone. METHODS Estimated GFR (eGFR) was calculated in SPK (n = 25) and LDK (n = 17) recipients in a stable phase 3 months after transplantation and annually during follow-up. Kidney graft biopsies were obtained at follow-up for measurement of glomerular volume (light microscopy), glomerular basement membrane (GBM) and podocyte foot process widths and mesangial volume fraction (electron microscopy). RESULTS SPK and LDK recipients were similar in age and diabetes duration at engraftment. Donor age was higher in the LDK group. Median follow-up time was 10.1 years. Mean HbA1c levels during follow-up were 5.5 ± 0.4% (37 ± 5 mmol/mol) and 8.3 ± 1.5% (68 ± 16 mmol/mol) in the SPK and LDK group, respectively (p < 0.001). Compared with SPK recipients, LDK recipients had wider GBM (369 ± 109 nm vs 281 ± 57 nm; p = 0.008) and increased mesangial volume fraction (median 0.23 [range 0.13-0.59] vs 0.16 [0.10-0.41]; p = 0.007) at follow-up. Absolute eGFR change from baseline was -11 ± 21 and -23 ± 15 ml min(-1) 1.73 m(-2) (p = 0.060), whereas eGFR slope was -1.1 (95% CI -1.7, -0.5) and -2.6 (95% CI -3.1, -2.1) ml min(-1) 1.73 m(-2) per year in the SPK and LDK group, respectively (p = 0.001). CONCLUSIONS/INTERPRETATION In patients with type 1 diabetes and long-term normoglycaemia after successful SPK transplantation, kidney graft ultrastructure and function were better preserved compared with LDK transplantation alone.

Abstract
Patients with type 1 diabetic end-stage renal disease (ESRD) may be offered single kidney transplantation from a live donor (LDK) or a deceased donor (DDK) to replace the lost kidney function. In the latter setting the patient may also receive a simultaneous pancreas together with a kidney from the same donor (SPK). Also in some cases a pancreas after kidney may be offered to those who have previously received a kidney alone (PAK). The obvious benefit of a successful SPK transplantation is that the patients not only recover from uremia but also obtain normal blood glucose control without use of insulin or other hypoglycemic agents. Accordingly, this combined procedure has become an established treatment for type 1 diabetic patients with ESRD. Adequate long-term blood glucose control may theoretically lead to reduced progression or even reversal of microvascular complications. Another potential beneficial effect may be improvement of patient and kidney graft survival. Development of diabetic complications usually takes a decade to develop and accordingly any potential benefits of a pancreas transplant will not easily be disclosed during the first decade after transplantation. The purpose of the review is to assess the present literature of outcomes after kidney transplantation in patients with diabetic ESRD, with our without a concomitant pancreas transplantation. The points of interest given in this review are microvascular complications, graft outcomes, cardiovascular outcomes and mortality.

Abstract
Type 1 diabetes mellitus (DM) is one of the most common and debilitating diseases to affect the world. Many patients are afflicted by microvascular and macrovascular complications, and succumb to end-stage renal disease (ESRD). Although dialysis and insulin therapy provides better glycemic control, it nonetheless significantly decreases a patient's quality of life. Moreover, they cannot reverse ESRD or alleviate complications. Simultaneous pancreas-kidney (SPK) transplantation has revolutionized the way we manage type 1 DM; it provides a physiological means of achieving normoglycemia while rendering patients free of dialysis. Understanding this procedure is important because it is becoming a more common management strategy for patients with type 1 DM. In this review, we will begin with a brief summary of type 1 DM, followed by a comprehensive description of SPK procedure, including the history and technique. We will then present the outcomes of transplantation.

Since the first pancreas transplants in the early 1960s, whole-organ pancreas transplantation, either alone or combined with kidney transplantation, has become commonplace in many countries around the world. Whole-organ pancreas transplantation is available in the UK, with ~200 transplants currently carried out per year. Patient survival and pancreas graft outcome rates are now similar to other solid organ transplant programmes, with high rates of long-term insulin independence. In the present review, we will discuss whole-pancreas transplantation as a treatment for diabetes, focusing on indications for transplantation, the nature of the procedure performed, graft survival rates and the consequences of pancreas transplantation on metabolic variables and the progression of diabetes-related complications.

Improved patient survival with simultaneous pancreas and kidney transplantation in recipients with diabetic end-stage renal disease. Diabetologia 2013; 56:1364-71. [PMID: 23549518 DOI: 10.1007/s00125-013-2888-y] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2012] [Accepted: 02/25/2013] [Indexed: 01/20/2023]
Abstract
AIMS/HYPOTHESIS We aimed to determine whether simultaneous pancreas and kidney (SPK) transplantation would improve patient and kidney graft survival in diabetic end-stage renal disease (ESRD) compared with kidney transplantation alone (KTA). METHODS Follow-up data were retrieved for all 630 patients with diabetic ESRD who had received SPK or KTA at our centre from 1983 to the end of 2010. Recipients younger than 55 years of age received either an SPK (n = 222) or, if available, a single live donor kidney (LDK; n = 171). Older recipients and recipients with greater comorbidity received a single deceased donor kidney (DDK; n = 237). Survival was analysed by the Kaplan-Meier method and in multivariate Cox regression analysis adjusting for recipient and donor characteristics. RESULTS Patient survival was superior in SPK compared with both LDK and DDK recipients in univariate analysis. Follow-up time (mean ± SD) after transplantation was 7.1 ± 5.7 years. Median actuarial patient survival was 14.0 years for SPK, 11.5 years for LDK and 6.7 years for DDK recipients. In multivariate analyses including recipient age, sex, treatment modality, time on dialysis and era, SPK transplantation was protective for all-cause mortality compared with both LDK (p = 0.02) and DDK (p = 0.029) transplantation. After the year 2000, overall patient survival improved compared with previous years (HR 0.40, 95% CI 0.30, 0.55; p < 0.001). Pancreas graft survival also improved after 2000, with a 5 year graft survival rate of 78% vs 61% in previous years (1988-1999). CONCLUSIONS/INTERPRETATION Recipients of SPK transplants have superior patient survival compared with both LDK and DDK recipients, with improved results seen over the last decade.

Abstract
BACKGROUND To describe the causes of graft loss, patient death and survival figures in kidney transplant patients in Spain based on the recipient's age. METHODS The results at 5 years of post-transplant cardiovascular disease (CVD) patients, taken from a database on CVD, were prospectively analysed, i.e. a total of 2600 transplanted patients during 2000-2002 in 14 Spanish renal transplant units, most of them receiving their organ from cadaver donors. Patients were grouped according to the recipient's age: Group A: <40 years, Group B: 40-60 years and Group C: >60 years. The most frequent immunosuppressive regimen included tacrolimus, mycophenolate mofetil and steroids. RESULTS Patients were distributed as follows: 25.85% in Group A (>40 years), 50.9% in Group B (40-60 years) and 23.19% in Group C (>60). The 5-year survival for the different age groups was 97.4, 90.8 and 77.7%, respectively. Death-censored graft survival was 88, 84.2 and 79.1%, respectively, and non death-censored graft survival was 82.1, 80.3 and 64.7%, respectively. Across all age groups, CVD and infections were the most frequent cause of death. The main causes of graft loss were chronic allograft dysfunction in patients <40 years old and death with functioning graft in the two remaining groups. In the multivariate analysis for graft survival, only elevated creatinine levels and proteinuria >1 g at 6 months post-transplantation were statistically significant in the three age groups. The patient survival multivariate analysis did not achieve a statistically significant common factor in the three age groups. CONCLUSIONS Five-year results show an excellent recipient survival and graft survival, especially in the youngest age group. Death with functioning graft is the leading cause of graft loss in patients >40 years. Early improvement of renal function and proteinuria together with strict control of cardiovascular risk factors are mandatory.

Abstract
Little is known on long-term outcomes in kidney transplantation. This study evaluated changes and predictors of generic and transplantation-specific health-related quality of life (HQoL) over six years in N = 102 kidney transplant survivors using the Short-form Health Survey-36 and the Transplant Effects questionnaire. Mixed models analysis was used to determine long-term outcomes. Emotional HQoL improved over time: Mental Component score, Mental Health, Energy (Ps = .000). Physical HQoL deteriorated: Physical Component Score (P = .001), Pain (P = .002). LRD transplant recipients had greater decline in physical functioning (P = .003) and PCS (P = .000) compared to cadaver recipients. Worry about the transplant (P = .036) and feelings of responsibility (P = .008) increased significantly over time. Worry about the transplant and perceived ability to work predicted 12.7% and 31.1% in variance in MCS and PCS, respectively. Efforts should be made to maintain HQoL and emotional outcomes with ongoing monitoring and support programs throughout the course of posttransplant care.

Abstract
Kidney transplantation is the treatment of choice for end-stage renal disease. The aim of this study was to determine the ten-year graft survival rate of renal transplantation in patients who have been transplanted from live donors. This is a historical cohort study designed to determine the organ survival rate after kidney transplantation from live donor during a 10-year period (from March 1999 to March 2009) on 843 patients receiving kidney transplant in the transplantation center of Namazi hospital in Shiraz, Iran. Kaplan-Meier method was used to determine the survival rate, log-rank test was used to compare survival curves, and Cox proportional hazard model was used to multivariate analysis. Mean follow-up was 53.07 ± 34.61 months. Allograft survival rates at 1, 3, 5, 7, and 10 years were 98.3, 96.4, 92.5, 90.8, and 89.2%, respectively. Using Cox proportional hazard model, the age and gender of the donors along with the creatinine level of the patients at discharge were shown to have a significant influence on survival. The 10-year graft survival rate of renal transplantation from living donor in this center is 89.2%, and graft survival rate in our cohort is satisfactory and comparable with reports from large centers in the world.

Abstract
BACKGROUND Renal transplantation is the best option for treatment of the end-stage renal diseases and has more advantages than dialysis. The objective of this study is to determine the ten-year graft survival rate of renal transplantation and its associated factors in patients who have been transplanted from March 1999 to March 2009 in Nemazee Hospital Transplantation Center. METHODS This is a historical cohort study of 1356 renal transplantation carried out during 1999 to 2009. Kaplan-Meier method was used to determine the survival rate, log rank test to compare survival curves, and Cox regression model to determine hazard ratios and for modeling of variables affecting survival. RESULTS The 1, 3, 5, 7 and 10 years graft survival rates were 96.6, 93.7, 88.9, 87.1 and 85.5 percent, respectively.Cox regression model revealed that the donor source and creatinine level at discharge were effective factors in graft survival rate in renal transplantation. CONCLUSION Our study showed that 10 year graft survival rate for renal transplantation in Nemazee Hospital Transplantation Center was 85.5% and graft survival rate was significantly related to recipients and donor's age,donor source and creatinine level at discharge. Our experience in renal transplantation survival rate indicates asuccess rate comparable to those noted in other reports.

Abstract
Diabetes mellitus remains one of the leading causes of morbidity and mortality worldwide. According to the Centers for Disease Control and Prevention, approximately 23.6 million people in the United States are affected. Of these individuals, 5-10% have been diagnosed with type 1 diabetes mellitus (TIDM), an autoimmune disease. Although it often appears in childhood, T1DM may manifest at any age. The effects of T1DM can be devastating, as the disease often leads to significant secondary complications, morbidity, and decreased quality of life. Since the late 1960s, surgical treatment for diabetes mellitus has continued to evolve and has become a viable alternative to chronic insulin administration. In this review, the historical evolution, current status, graft efficacy, benefits, and complications of pancreas transplantation are explored.

Abstract
BACKGROUND Type 1 diabetes mellitus is a chronic condition often leading to disabling complications including retinopathy, neuropathy and cardiovascular disease which can be modified by intensive treatment with insulin. Such treatment, however, is associated with a restrictive lifestyle and risk of hypoglycaemic morbidity and mortality. METHODS This review examines the role of pancreas transplantation in patients with Type 1 diabetes mellitus. RESULTS Pancreas transplantation is currently the only proven option to achieve long-term insulin independence, resulting in an improvement or stabilization of those diabetic related complications. The hazards of pancreas transplantation as a major operation are well known. Balancing the risks of a surgical procedure, with the benefits of restoring normoglycaemia remains an important task for the pancreas transplant surgeon. Pancreas transplantation is not an emergency operation to treat poorly managed and non-compliant patients with debilitating complications. It is a highly specialized procedure which has evolved both in terms of the surgical technique, patient selection and assessment. CONCLUSION Pancreas transplantation has emerged as the single most effective way to achieve normal glucose homeostasis in patients with Type 1 diabetes mellitus.

Abstract
As result of improved surgical techniques and newer immunosuppressive regimens contributing significantly to better graft survival, exocrine pancreas transplantation remains the standard treatment of choice for patients with diabetes mellitus complicated by end-stage renal disease. Histologic assessment continues to play an important role in the diagnosis of graft complications after pancreas transplantation, especially for evaluating allograft rejection where histopathology is still considered the gold standard. This review elaborates on the current types of pancreas transplants and focuses on the patterns of allograft injury that are encountered in posttransplantation pancreas biopsies along with the pertinent differential diagnoses. In addition to optimal histologic assessment, as in any other organ transplant setting, clinical information including indication and duration of transplant as well as other serologic work-up must be taken into consideration during clinical decision making for optimal graft outcome.

Abstract
PURPOSE OF REVIEW The goal of pancreas transplantation is to restore normoglycemia in patients with labile diabetes. The results of this procedure improved over the years, but, although pancreas transplantation is not considered experimental anymore, there is often reluctance to recommend this procedure because of the complexity, especially for solitary pancreas transplants. This article reviews the current status of pancreas transplantation. RECENT FINDINGS Many improvements have been made in the surgical techniques and immunosuppressive regimens. The overall rate of technical problems decreased, yet immunologic graft loss is still a problem in solitary pancreas transplants. Careful donor selection significantly decreased the risk of graft failure and therefore improved patient survival. SUMMARY With modern immunosuppressive protocols and careful donor selection, patient survival rates and pancreas transplant graft function can be further improved in all three pancreas transplant categories.

Abstract
Advances in technical aspects of pancreas transplantation and improvements in immunosuppression over the last decade have led to significant improvements in pancreas transplant outcomes in the short-term. Simultaneous kidney pancreas transplantation remains an attractive option for patients with type 1 diabetes (T1DM) and late chronic kidney disease (CKD), with 1-year pancreas graft survival rates of 86% in 2004. For the individual patient with T1DM and CKD, the various transplant options must be considered carefully, with attention to the timing of surgery relative to the need for dialysis, the challenge in managing diabetes with noninvasive medical therapy, and the assumption of risks attendant to each surgical option. This review summarizes the current status of simultaneous pancreas kidney transplantation and compares and contrasts outcomes with other potential treatment options.

Abstract
In this single-institution study, we compared outcomes in diabetic recipients of living donor (LD) kidney transplants that did vs. did not undergo a subsequent pancreas transplant. Of 307 diabetic recipients who underwent LD kidney transplants from January 1, 1995, through December 31, 2003, a total of 175 underwent a subsequent pancreas after kidney (PAK) transplant; 75 were deemed eligible (E) for, but did not receive (for personal or financial reasons), a PAK, and thus had a kidney transplant alone (KTA); and 57 deemed ineligible (I) for a PAK because of comorbidity also had just a KTA. We analyzed the three groups (PAK, KTA-E, KTA-I) for differences in patient characteristics, glycemic control, renal function, patient and kidney graft survival rates, and causes of death. Kidney graft survival rates (actuarial) were similar in the PAK vs. KTA-E groups at one, five, and 10 yr post-transplant: 98%, 82%, and 67% (PAK) vs. 100%, 84%, and 62% (KTA-E) (p = 0.9). The long-term (greater than four yr post-transplant) estimated glomerular filtration rate (GFR) was higher in the PAK than in the KTA-E group: 53 +/- 20 mL/min (PAK) vs. 43 +/- 16 mL/min (KTA-E) (p = 0.016). The patient survival rates were also similar for the PAK and KTA-E groups. We conclude that the subsequent transplant of a pancreas after an LD kidney transplant does not adversely affect patient or kidney graft survival rates; in fact, it is associated with better long-term kidney graft function.

Abstract
Since the introduction of pancreas transplantation more than 40 years ago, efforts to develop more minimally invasive techniques for endocrine replacement therapy have been in progress, yet this surgical procedure still remains the treatment of choice for diabetic patients with end-stage renal failure. Many improvements have been made in the surgical techniques and immunosuppressive regimens, both of which have contributed to an increasing number of indications for pancreas transplantation. This operation can be justified on the basis that patients replace daily injections of insulin with an improved quality of life but at the expense of a major surgical procedure and lifelong immunosuppression. The various indications, categories, and outcomes of patients having a pancreas transplant are discussed, particularly with reference to the effect on long-term diabetic complications.

Abstract
BACKGROUND AND OBJECTIVES Simultaneous pancreas-kidney transplantation (SPK) is regarded as the treatment of choice for type 1 diabetes (T1DM) and kidney dysfunction, despite the morbidity associated with pancreas transplantation. These morbidities often influence selection of SPK versus living-donor kidney alone (LD KA) transplant. This study quantifies the impact of pancreas graft function on outcomes following SPK. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Using the SRTR database, SPK wait-listed patients transplanted from 1997 to 2005 were evaluated and segregated as: (1) SPK recipients with functioning pancreas graft 12 mo posttransplant (SPK, P+); (2) SPK recipients with loss of pancreas graft function within 12 mo posttransplant (SPK, P-); (3) recipients of deceased donor (DD) KA; (4) recipients of LD KA. The study compared patient and kidney graft survival to 84 mo posttransplant. RESULTS Patient survival for SPK, P+ was significantly better than the LD KA; SPK, P-; and DD KA cohorts (88.6% versus 80.0%, 73.9% and 64.8%, respectively [P < 0.001]), a finding confirmed by multivariate analysis and not influenced by pancreas-after-kidney transplantation (PAK) rates and outcomes. Unadjusted graft survival was also highest in the SPK, P+ cohort (72.0% versus 63.6%, 59.8%, 49.7%, P = 0.015 versus LD KA). CONCLUSIONS SPK recipients with functioning pancreas grafts have superior survival compared with LD KA and DD KA, including in the setting of PAK. Early pancreas graft failure results in kidney and patient survival rates similar to KA. These data help further clarify the decision-making of SPK versus KA transplant options for patients and providers.

Abstract
OBJECTIVE To quantify the incremental survival benefit of the pancreas allograft in simultaneous pancreas-kidney (SPK) transplant recipients. RESEARCH DESIGN AND METHODS Data from the national transplant database from 2000 to 2007 were analyzed. SPK recipients who had functioning allografts to 1-year post transplant (n = 3,304) were compared with those who had failure of the renal (n = 233) or pancreatic (n = 112) graft. The main outcome was a projection of 10 life-years of patient survival beyond the first transplant anniversary. RESULTS Recipients with function of both organs accrued 9.4 life-years following transplantation. Projected survival in patients with kidney failure was reduced to 2.5 life-years. Pancreas failure reduced predicted survival to 8 life-years. Renal allograft failure impacts life expectancy significantly (adjusted hazard ratio [aHR] 12.13). However, pancreas allograft failure was also associated with reduced survival (aHR 2.62). CONCLUSIONS Although the majority of the survival benefit of SPK transplant is due to the renal transplant, pancreas allograft function does contribute to patient survival.

Abstract
BACKGROUND AND OBJECTIVES Transplant options for type I diabetics with end-stage renal disease include simultaneous pancreas-kidney (SPKT), living donor kidney (LDKT), and deceased donor kidney transplant (DDKT). It is unclear whether SPKT offers a survival benefit over LDKT in the current era of transplantation. The authors compared outcomes of kidney transplant recipients with type I diabetes using data from the Organ Procurement and Transplant Network/United Network for Organ Sharing. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Adult (age 20 to 59) type I diabetics who received a solitary first-time kidney transplant between 2000 and 2007 were studied. Outcomes included overall kidney graft and patient survival. Multivariate analysis was performed using a stepwise Cox proportional hazards model. RESULTS Kidney graft survival was better for recipients of LDKT compared with SPKT (P = 0.008), although patient survival was similar (P = 0.346). On multivariate analysis, LDKT was associated with lower adjusted risks over 72 mo follow-up of kidney graft failure (HR 0.71; 95% CI 0.61 to 0.83) and patient death (HR 0.78; 95% CI 0.65 to 0.94) versus SPKT. Compared with DDKT, SPKT had superior unadjusted kidney graft and patient survival, partly due to favorable SPKT donor and recipient factors. CONCLUSIONS Despite more transplants from older donors and among older recipients, LDKT was associated with superior outcomes compared with SPKT and was coupled with the least wait time and dialysis exposure. LDKT utilization should be considered in all type I diabetics with an available living donor, particularly given the challenges of ongoing organ shortage.

Alemtuzumab induction and antibody-mediated kidney rejection after simultaneous pancreas-kidney transplantation. Transplantation 2009; 87:125-32.

Abstract
BACKGROUND The best induction agent for simultaneous pancreas-kidney transplantation (SPKT) remains the subject of debate. Alemtuzumab is effective in preventing acute cellular rejection (ACR) in SPK recipients and has been used to prevent antibody-mediated rejection (AMR) in sensitized kidney transplant candidates. METHODS A retrospective cohort study was performed including 136 SPK recipients receiving maintenance immunosuppression with tacrolimus, mycophenolic acid prodrugs, and prednisone. Two groups were compared: those who received induction with alemtuzumab (n=97) and those induced with basiliximab (n=39). RESULTS Kidney ACR was more frequent in SPKT induced with basiliximab (2-year 12.8% vs. 3.1%, P=0.04), but the incidence of AMR was similar (2-year 18% with basiliximab vs. 13.8% with alemtuzumab, P=NS). Kidney rejection was associated with clinical pancreas rejection in 70% of cases, without differences between the groups. Postrejection kidney graft survival was similar in both groups (2-year basiliximab/alemtuzumab 94.7%/91.2%), but death-censored kidney graft survival was lower with alemtuzumab (100%/91.2%, P=0.056). In the basiliximab group, the predominant cause of kidney loss was death-with-function, whereas in the alemtuzumab group AMR accounted for all losses. Pancreas graft survival was similar in both groups, yet more pancreas losses due to acute rejection occurred in alemtuzumab-treated patients (4 vs. 1). CONCLUSIONS Kidney AMR is more common than ACR in SPKT recipients treated with alemtuzumab, tacrolimus, mycophenolic acid, and steroids. ACR is better prevented by alemtuzumab than basiliximab, but no relevant difference is found in prevention of AMR. Despite the high incidence of AMR, survival rates are excellent in both groups.

Abstract
BACKGROUND We hypothesized that many reported and presumed isolated pancreas acute rejection episodes in simultaneous pancreas kidney patients may in fact be missed concordant kidney acute rejection episodes. METHODS To test this hypothesis, we undertook an analysis of the Organ Procurement and Transplant Network database from 1995 to 2006 to assess the impact of reported isolated pancreas rejection on kidney allograft outcomes. The primary outcome of interest was kidney graft status beyond the first posttransplant year. RESULTS For overall graft survival, we found that when pancreas alone rejection was compared with no rejection there was a significant difference between the curves (log-rank P<0.0001). In addition, this endpoint was also significant for death censored graft survival (log-rank P=0.0036). For both overall and death censored graft survival the multivariate analyses demonstrated an increased risk (adjusted hazards ratio: 2.46, 3.22, respectively) for patients reported to have pancreas alone rejection. CONCLUSIONS These results indicate that patients with isolated pancreas rejection have worse renal allograft survival than patients reported as having no acute rejection and fare at least as poorly as those with reported kidney graft rejection supporting the concept of concordance of acute rejection in the majority of patients.
