Abstract
BACKGROUND To address long waitlist times and increase pancreas transplantation, our center has implemented a protocol for long-distance importation of pancreata. METHODS We conducted a retrospective review of pancreas transplantation at our institution from January 1, 2014, the start of our importation program, through September 30, 2021. Outcomes were compared between locally procured grafts and imported grafts, defined as grafts procured greater than 250 nautical miles (NM) from our center. RESULTS Eighty-one patients underwent pancreas transplantation during the study time period; 19 (23.5%) received imported grafts. There were no significant differences in recipient demographics or type of transplant received. Mean distance of import was 644.2 ± 234.0 NM. Imported grafts were more likely to be from pediatric donors <18 years old (p = .02) and a significantly higher proportion of imported grafts came from donors weighing <30 kg (26.3 vs. 3.2%, p = .007). Cold ischemic time was longer for imported grafts than for local grafts (13.4 ± 2.3 h vs. 9.8 ± 2.2 h, p < .01). There was no significant difference in deaths or graft losses within 90 days or at 1 year between groups. CONCLUSION Centers should consider expanding criteria for acceptance of imported pancreata to increase the number of transplants and combat organ nonutilization.

Abstract
Pancreas transplantation (PTx) reestablishes an autoregulating source of endogenous insulin responsive to normal feedback controls. In addition to achieving complete β-cell replacement that frees the patient with diabetes from the need to monitor serum glucose and administer exogenous insulin, successful PTx provides counterregulatory hormone secretion and exocrine function. A functioning PTx mitigates glycemic variability, eliminates the daily stigma and burden of diabetes, restores normal glucose homeostasis in patients with complicated diabetes, and improves quality of life and life expectancy. The tradeoff is that it entails a major surgical procedure and requisite long-term immunosuppression. Despite the high likelihood of rendering patients euglycemic independent of exogenous insulin, PTx is considered a treatment rather than a cure. In spite of steadily improving outcomes in each successive era coupled with expansion of recipient selection criteria to include patients with a type 2 diabetes phenotype, a decline in PTx activity has occurred in the new millennium related to a number of factors including: (1) lack of a primary referral source and general acceptance by the diabetes care community; (2) absence of consensus criteria; and (3) access, education, and resource issues within the transplant community. In the author's experience, patients who present as potential candidates for PTx have felt as though they needed to circumvent the conventional diabetes care model to gain access to transplant options. PTx should be featured more prominently in the management algorithms for patients with insulin requiring diabetes who are failing exogenous insulin therapy or experiencing progressive diabetic complications regardless of diabetes type. Furthermore, all patients with diabetes and chronic kidney disease should undergo consideration for simultaneous pancreas-kidney transplantation independent of geography or location.

Abstract
Background: Prior to year 2000, the majority of pancreas transplants (PTx) were performed as simultaneous pancreas-kidney transplants (SPKTs) in Caucasian adults with end stage renal failure secondary to type 1 diabetes mellitus (T1DM) who were middle-aged. In the new millennium, improving outcomes have led to expanded recipient selection that includes patients with a type 2 diabetes mellitus (T2DM) phenotype, which excessively affects minority populations. Methods: Using PubMed® to identify appropriate citations, we performed a literature review of PTx in minorities and in patients with a T2DM phenotype. Results: Mid-term outcomes with SPKT in patients with uremia and circulating C-peptide levels (T2DMphenotype) are comparable to those patients with T1DM although there may exist a selection bias in the former group. Excellent outcomes with SPKT suggests that the pathophysiology of T2DM is heterogeneous with elements consisting of both insulin deficiency and resistance related to beta-cell failure. As a result, increasing endogenous insulin (Cp) production following PTx may lead to freedom checking blood sugars or taking insulin, better metabolic counter-regulation, and improvements in quality of life and life expectancy compared to other available treatment options. Experience with solitary PTx for T2DM or in minorities is limited but largely mirrors the trends reported in SPKT. Conclusions: PTx is a viable treatment option in patients with pancreas endocrine failure who are selected appropriately regardless of diabetes type or recipient race. This review will summarize data that unconventional patient populations with insulin-requiring diabetes may gain value from PTx with an emphasis on contemporary experiences and appropriate selection in minorities in the new millennium.

Pancreas Transplantation for Type 2 Diabetes: A Systematic Review, Critical Gaps in the Literature, and a Path Forward. Transplantation 2022; 106:1916-1934.

Abstract
Pancreas transplantation in patients with type 2 diabetes (T2D) remains relatively uncommon compared with pancreas transplantation in patients with type 1 diabetes (T1D); however, several studies have suggested similar outcomes between T2D and T1D, and the practice has become increasingly common. Despite this growing interest in pancreas transplantation in T2D, no study has systematically summarized the data to date. We systematically reviewed the literature on pancreas transplantation in T2D patients including patient and graft survival, glycemic control outcomes, and comparisons with outcomes in T2D kidney transplant alone and T1D pancreas transplant recipients. We searched biomedical databases from January 1, 2000, to January 14, 2021, and screened 3314 records, of which 22 full texts and 17 published abstracts met inclusion criteria. Full-text studies were predominantly single center (73%), whereas the remaining most often studied the Organ Procurement and Transplantation Network database. Methodological quality was mixed with frequent concern for selection bias and concern for inconsistent definitions of both T2D and pancreas graft survival across studies. Overall, studies generally reported favorable patient survival, graft survival, and glycemic control outcomes for pancreas transplantation in T2D and expressed a need to better characterize the T2D patients who would benefit most from pancreas transplantation. We suggest guidance for future studies, with the aim of supporting the safe and evidence-based treatment of end-stage T2D and judicious use of scarce resources.

Abstract
Following simultaneous pancreas-kidney transplantation (SPKT), survival outcomes are reported as equivalent in patients with detectable pretransplant C-peptide levels (Cp+) and a "type 2″ diabetes mellitus (DM) phenotype compared to type 1 (Cp negative [Cp-]) DM. We retrospectively compared 46 Cp+ patients pretransplant (≥2.0 ng/mL, mean 5.4 ng/mL) to 46 Cp- (level < 0.5 ng/mL) case controls matched for recipient age, gender, race, and transplant date. Early outcomes were comparable. Actual 5-year patient survival (91% versus 94%), kidney graft survival (69% versus 86%, p = .15), and pancreas graft survival (60% versus 86%, p = .03) rates were lower in Cp+ versus Cp- patients, respectively. The Cp+ group had more pancreas graft failures due to insulin resistance (13% Cp+ versus 0% Cp-, p = .026) or rejection (17% Cp+ versus 6.5% Cp-, p = .2). Post-transplant weight gain > 5 kg occurred in 72% of Cp+ versus 26% of Cp- patients (p = .0001). In patients with functioning grafts, mean one-year post-transplant HbA1c levels (5.0 Cp+ versus 5.2% Cp-) were comparable, whereas Cp levels were higher in Cp+ patients (5.0 Cp+ versus 2.6 ng/mL Cp-). In this matched case-control study, outcomes were inferior in Cp+ compared to Cp- patients following SPKT, with post-transplant weight gain, insulin resistance, and rejection as potential mitigating factors.

Abstract
Studies have found similar outcomes of Simultaneous Pancreas-Kidney transplantation (SPKT) in patients with Type 2 (T2D) and Type 1 diabetes (T1D). However, there are scarce data evaluating the association of recipient factors such as age, BMI, or pretransplant insulin requirements with outcomes, thus the criteria for the optimal recipient selection remains unclear. In this study, 284 T1D and 39 T2D patients, who underwent SPKT between 2006 and 2017 with 1 year of follow-up at minimum, were assessed for potential relationship of pretransplant BMI and insulin requirements with posttransplant diabetes and pancreatic graft failure. Kaplan-Meier analysis showed similar rates of freedom from posttransplant diabetes (94.7% T2D vs. 92.3% T1D at 1 yr, and 88.1% T2D vs. 81.1% T1D at 5 yrs) and graft survival (89.7% T2D vs. 90.4% T1D at 1 yr, and 89.7% T2D vs. 81.2% T1D at 5 yrs). There was no significant association between BMI or pretransplant insulin requirements with posttransplant diabetes occurrence in either T1D (p = .10, .43, respectively) or T2D (p = .12, .63) patients in the cohort; or with graft failure (T1D: p = .40, .09; T2D: p = .71, .28). These observations suggest a less restricted approach to selective use of SPKT in patients with T2D.

Abstract
PURPOSE OF REVIEW The vast majority of cases of diabetes mellitus (DM) in the United States are classified as type 2 DM (T2DM). Restrictive listing criteria and uncertainty regarding outcomes have historically limited access to pancreas transplantation for individuals with T2DM, although it has been used with success in patients with type 1 DM (T1DM). This review summarizes several recent studies that have sought to clarify the indications, appropriate patient selection, and outcomes of pancreas transplantation in the setting of T2DM. RECENT FINDINGS Pancreas transplants have increased over the last few years, largely due to an increase in listings for simultaneous pancreas-kidney transplant (SPK) in patients with T2DM. Retrospective data demonstrate similar patient and allograft survival in patients with T1DM and T2DM undergoing SPK, and improved outcomes in patients with T2DM after SPK compared to those receiving a kidney transplant alone, although these studies are often confounded by selection biases. Patient selection for pancreas transplant has traditionally focused on body mass index, pretransplant insulin requirements, and fasting C-peptide, and the categorization of patients to T1DM or T2DM. Emerging data suggests this practice is inadvertently and unnecessarily restrictive. SUMMARY There is a growing body of evidence to support increasing consideration of pancreas transplantation in patients with T2DM, with support for equivalent patient and graft survival and glycemic control. Future prospective studies are indicated to better evaluate the role of preoperative patient factors in selection for pancreas transplantation and to explore long-term outcomes in patients with T2DM.

Abstract
In this study, we aimed to compare the metabolic outcomes, renal function, and survival outcomes of simultaneous pancreas and kidney transplantation (SPK) and kidney transplantation alone (KTA) among end‐stage kidney disease (ESKD) patients with type II diabetes mellitus (T2DM). Patients with ESKD and T2DM who underwent KTA (n = 85) or SPK (n = 71) in a transplant center were retrospectively reviewed. Metabolic profiles, renal function, and survival outcomes were assessed repeatedly at different follow‐up time points. Propensity score procedures were applied to enhance between‐group comparability. The levels of renal and metabolic outcomes between SPK and KTA over time were examined and analyzed using mixed‐model repeated‐measures approaches. The median follow‐up period was 1.8 years. Compared with KTA, SPK resulted in superior metabolic outcomes and renal function, with lower levels of glycated hemoglobin (HbA1c; P = 0.0055), fasting blood glucose (P < 0.001), triglyceride (P = 0.015), cholesterol (P = 0.0134), low‐density lipoprotein (P = 0.0161), and higher estimated glomerular filtration rate (eGFR; P < 0.001). SPK provided better metabolic outcomes and renal function. The survival outcomes of the recipients and grafts were comparable between the two groups.

Three-month pancreas graft function significantly influences survival following simultaneous pancreas-kidney transplantation in type 2 diabetes patients. Am J Transplant 2020; 20:788-796.

Abstract
Successful simultaneous pancreas-kidney transplantation (SPK) improves quality-of-life and prolongs kidney allograft and patient survival in type-1 diabetic (T1DM) patients. However, the use of SPK in type-2 diabetic (T2DM) patients remains limited. We examined a national transplant registry for 35 849 T2DM kidney disease patients who received transplant between 2000 and 2016 and survived the first 3 months with a functioning kidney, and categorized as: deceased-donor kidney transplant alone (DD-KA, 68%), living-donor kidney transplant alone (LD-KA, 30%), or SPK (2%). Among SPK recipients, 6% had pancreas allograft failure within 3 months (SPK,P-) and 94% had a functional pancreas (SPK,P+). Associations of transplant type with kidney allograft failure and death (multivariable-adjusted hazard ratio, 95%LCL aHR95%UCL ), over follow-up through December 2018, were quantified by multivariable inverse probability of treatment weighted survival analyses. SPK recipients had better kidney graft and patient survival than LD-KA or DD-KA recipients. Compared to SPK,P+, DD-KA, or LD-KA recipients had significantly higher risk of kidney allograft failure (DD-KA: aHR 1.53 2.203.17 ; LD-KA: aHR 1.29 1.872.71 ) and death (DD-KA: aHR 2.12 3.255.00 ; LD-KA: aHR 1.54 2.353.59 ). SPK,P- recipients had significantly higher risk of death (aHR 1.68 3.306.50 ). Similar to T1DM, T2DM patients with SPK have a survival benefit compared to those with kidney transplant alone, but this benefit depends upon successful early pancreas function.

Abstract
BACKGROUND Simultaneous pancreas-kidney (SPK) transplants for patients with type 1 diabetes mellitus (T1DM) remains disproportionately higher than that for type 2 diabetes mellitus (T2DM) patients. However, understanding the surgical outcomes for these patients is not well described. Therefore, the results of DM patients with end-stage renal disease and their transplantations were reported. METHODS Between September 2016 and June 2019, 63 SPK transplants were performed in our organ transplantation center. χ2 and t-test compared the variables between the groups and the record review verified the patient survival. Using Kaplan-Meier survival estimates and Cox proportional hazards regression, we examined the influence of SPK on patient and graft survivals. RESULTS Sixty-three SPK transplantation was performed, 18 (29%) were T1DM, and 45 (71%) T2DM. T2DM recipients had older age, duration of diabetes, and pretransplant dialysis time. No differences were found in human leukocyte antigen (HLA) mismatch, body mass index (BMI), and other variables. Patient survivals for T1DM was 98.2% and 94.8% at 1 and 2 years vs. 100% and 94.1% for T2DM recipients (P=0.87). There was no increased risk between kidney disease, pancreas failure, or death when comparing T2DM and T1DM. CONCLUSIONS In our single-center cohort of SPK transplants, we concluded that SPK recipients with T2DM diagnosis were not at increased risk for death, kidney failure, or pancreas failure when compared with recipients with T1DM.

Abstract
Obesity is considered a relative contraindication to pancreas transplantation due to an overall increased risk in wound-related complications and surgical site infections. The rationale for performing pancreas transplantation in a minimally invasive fashion is to reduce these risks, which can be associated with inferior patient and graft survival following pancreas transplantation in morbidly obese patients. At the University of Illinois at Chicago, the initial series of robotic-assisted pancreas transplantation in obese patient with type 1 and 2 diabetes has been performed. In this article, surgical technique and world experience in robotic pancreas transplantation are described.

Abstract
PURPOSE OF REVIEW Advances in surgical technique and immunosuppression have significantly improved outcomes after pancreas transplantation, and as a result pancreas transplants increasingly are being performed for indications other than type 1 diabetes mellitus. This review summarizes the current literature on pancreas transplantation in unconventional recipient populations. RECENT FINDINGS An increasing body of work suggests that pancreas transplantation can be performed with good outcomes in patients with type 2 diabetes mellitus and those 50 years of age and older. Obesity appears detrimental to patient and pancreas graft survival, and bariatric surgery prior to transplantation may be of increasing interest and relevance. There are limited data yielding mixed outcomes on pancreas transplantation in patients with HIV or hepatitis C virus. However, rapidly improving antiviral therapies are prolonging survival in patients with HIV and chronic hepatitis C virus infections and may increase the number of candidates available for pancreas transplantation in these populations in the future. SUMMARY Despite limited literature in these patient populations, pancreas transplantation may be a viable treatment option for endocrine pancreas failure in appropriately selected patients regardless of disease cause or age.

Abstract
BACKGROUND Limited data are available regarding the long-term metabolic outcomes of functioning pancreas transplants in patients with type 2 diabetes mellitus (T2DM). METHODS To compare the long-term effects of pancreas transplantation in terms of insulin resistance and β cell function, comparison of metabolic variables was performed between type 1 diabetes mellitus (T1DM) and T2DM patients from 1-month posttransplant to 5 years using generalized, linear-mixed models for repeated measures. RESULTS Among 217 consecutive patients who underwent pancreas transplantation at our center between August 2004 and January 2015, 193 patients (151 T1DM and 42 T2DM) were included in this study. Throughout the follow-up period, postoperative hemoglobin A1c did not differ significantly between T1DM and T2DM patients, and the levels were constantly below 6% (42 mmol/mol) until 5 years posttransplant, whereas C-peptide was significantly higher in T2DM (P = 0.014). There was no difference in fasting insulin, homeostasis model assessment (HOMA) of insulin resistance, HOMA β cell, or the insulinogenic index between the groups. Furthermore, fasting insulin and HOMA-insulin resistance steadily decreased in both groups during the follow-up period. CONCLUSIONS There was no significant difference in the insulin resistance or β-cell function after pancreas transplantation between T1DM and T2DM patients. We demonstrated that pancreas transplantation is capable of sustaining favorable endocrine functions for more than 5 years in T2DM recipients.

Abstract
PURPOSE OF REVIEW Pancreas transplantation remains the best long-term treatment option to achieve euglycemia and freedom from insulin in patients with labile diabetes mellitus. It is an approved procedure for type 1 (T1DM), but it is still considered controversial for type 2 diabetes mellitus (T2DM). RECENT FINDINGS This study analyzed all primary deceased donor pancreas transplants in patients with T2DM reported to IPTR/UNOS between 1995 and 2015. Characteristics, outcomes, and risk factors over time were determined using univariate and multivariate methods. The focus was on simultaneous pancreas/kidney (SPK) transplants, the most common pancreas transplant category. Patient, pancreas, and kidney graft survival rates increased significantly over time and reached 95.8, 83.3, and 91.1%, respectively, at 3 years posttransplant for transplants performed between 2009 and 2015. SPK is a safe procedure with excellent pancreas and kidney graft outcome in patients with T2DM. The procedure restores euglycemia and freedom from insulin and dialysis. Based on our results, SPK should be offered to more uremic patients with labile T2DM.

Abstract
Whole-organ pancreas transplantation, either alone or combined with a kidney transplant, is the only definitive treatment for many patients with type 1 diabetes that restores normal glucose homoeostasis and insulin independence. Pancreas transplantation delays, or potentially prevents, secondary diabetes complications and is associated with improvement in patient survival when compared with either patients remaining on the waiting list or those receiving kidney transplant alone. Pancreas transplantation is safe and effective, with 1-year patient survival >97 % and graft survival rates of 85 % at 1 year and 76 % at 5 years in recent UK data. This review focuses on some current areas of interest in pancreas transplantation.

Abstract
Kidney transplantation has proven to be the gold standard therapy for severe chronic kidney disease (CKD) due to multiple etiologies in individuals deemed eligible from a surgical standpoint. While kidney transplantation is traditionally considered in conditions of native kidney disease such as diabetes and immunological or inherited causes of kidney disease, an increasing indication for kidney transplantation is kidney dysfunction in the setting of other severe organ dysfunction that requires transplant, such as severe liver or heart disease. In these settings, multiorgan transplantation is now commonly performed, with controversy regarding the appropriate utilization of kidneys transplanted both from a physiological perspective (distinguishing those who require a kidney transplant) and also from an ethical perspective (allocation of a scarce resource to a more morbid population). These issues persist in the setting of simultaneous pancreas-kidney transplant (SPK), in which utilization for patients with type 1 diabetes has been historically accepted. Questions of physiological benefit persist, and utilization is waning despite broader allocation policies that encourage SPK, including consideration for patients with type 2 diabetes. The purpose of this review will be to summarize the physiological data regarding multiorgan transplantation and place these into context while reviewing current allocation policy in the United States.

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
Metabolic surgery for the treatment of type 2 diabetes mellitus (T2DM) in patients not morbidly obese (BMI <35) has been widely studied. Taking into account that ∼12% of pancreas transplants are performed in patients with T2DM, our goal was to evaluate the impact of metabolic surgery on the management of obese patients with T2DM on waiting lists for a pancreas transplant. We performed a Roux-en-Y gastrointestinal bypass in 5 patients with insulin-dependent T2DM who were candidates for pancreas after kidney transplant and with a BMI <35. Three patients became insulin independent by the end of the first year while the other 2 reduced their insulin requirements by 70%. Furthermore, all patients achieved improved control of lipid levels. We concluded that the surgery was effective in controlling blood glucose and lipid metabolism in these obese T2DM kidney transplant recipients. In this population, a pancreas transplant, along with its associated morbidity, may be avoided.

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
Although the diagnosis of type 2 diabetes mellitus was once considered a contraindication to simultaneous pancreas-kidney transplantation, a growing body of evidence has revealed that similar graft and patient survival can be achieved when compared to type 1 diabetes mellitus recipients. A cautious strategy regarding candidate selection may limit appropriate candidates from additional benefits in terms of quality of life and potential amelioration of secondary side effects of the disease process. Although our current understanding of the disease has changed, uniform listing characteristics to better define and study this population have limited available data and must be established.

Abstract
BACKGROUND In the past, type 2 (C-peptide positive) diabetes mellitus (DM) was a contraindication for simultaneous pancreas-kidney transplantation (SPKT). STUDY DESIGN We retrospectively analyzed outcomes in SPKT recipients according to pretransplantation C-peptide levels ≥ 2.0 ng/mL or < 2.0 ng/mL. RESULTS From November 2001 to March 2013, we performed 162 SPKTs including 30 (18.5%) in patients with C-peptide levels ≥ 2.0 ng/mL pretransplantation (C-peptide positive group, range 2.1 to 12.4 ng/mL) and 132 in patients with absent or low C-peptide levels (<2.0 ng/mL, C-peptide "negative"). C-peptide positive patients were older at SPKT, had a later age of onset and shorter duration of pretransplantation DM, and more were African-American (all p < 0.05) compared with C-peptide negative patients. With a mean follow-up of 5.6 years, patient (80% vs 82.6%), kidney graft (63.3% vs 68.9%), and pancreas graft survivals (50% vs 62.1%, all p = NS) rates were comparable in C-peptide positive and negative patients, respectively. At latest follow-up, there were no differences in acute rejection episodes, surgical complications, major infections, readmissions, hemoglobin A1c levels, serum creatinine, and estimated glomerular filtration rate levels between the 2 groups. C-peptide levels were higher (mean 5.0 vs 2.6 ng/mL, p < 0.05) and post-transplant weight gain (≥ 5 kg) was more common (57% vs 33%, p = 0.004) in the C-peptide positive group. Survival outcomes in C-peptide positive (n = 14) vs C-peptide negative (n = 22) African-American patients were similar, as were outcomes in C-peptide positive patients with a body mass index < or ≥ 28 kg/m(2). CONCLUSIONS Patients with higher pretransplantion C-peptide levels appear to have a type 2 DM phenotype compared to insulinopenic patients undergoing SPKT. However, survival and functional outcomes were similar, suggesting that pretransplantation C-peptide levels should not be used exclusively to determine candidacy for SPKT.

Fourtounas C. Transplant options for patients with type 2 diabetes and chronic kidney disease. World J Transplant 2014; 4:102-110.

Abstract
Chronic kidney disease (CKD) has become a real epidemic around the world, mainly due to ageing and diabetic nephropathy. Although diabetic nephropathy due to type 1 diabetes mellitus (T1DM) has been studied more extensively, the vast majority of the diabetic CKD patients suffer from type 2 diabetes mellitus (T2DM). Renal transplantation has been established as a first line treatment for diabetic nephropathy unless there are major contraindications and provides not only a better quality of life, but also a significant survival advantage over dialysis. However, T2DM patients are less likely to be referred for renal transplantation as they are usually older, obese and present significant comorbidities. As pre-emptive renal transplantation presents a clear survival advantage over dialysis, all T2DM patients with CKD should be referred for early evaluation by a transplant center. The transplant center should have enough time in order to examine their eligibility focusing on special issues related with diabetic nephropathy and explore the best options for each patient. Living donor kidney transplantation should always be considered as the first line treatment. Otherwise, the patient should be listed for deceased donor kidney transplantation. Recent progress in transplantation medicine has improved the “transplant menu” for T2DM patients with diabetic nephropathy and there is an ongoing discussion about the place of simultaneous pancreas kidney (SPK) transplantation in well selected patients. The initial hesitations about the different pathophysiology of T2DM have been forgotten due to the almost similar short- and long-term results with T1DM patients. However, there is still a long way and a lot of ethical and logistical issues before establishing SPK transplantation as an ordinary treatment for T2DM patients. In addition recent advances in bariatric surgery may offer new options for severely obese T2DM patients with CKD. Nevertheless, the existing data for T2DM patients with advanced CKD are rather scarce and bariatric surgery should not be considered as a cure for diabetic nephropathy, but only as a bridge for renal transplantation.

Abstract
In the setting of organ scarcity, the ethics of multi-organ transplantation (MOT) deserve new examination. MOT offers substantial benefits to certain recipients, including avoiding serial surgeries. However, MOT candidates in the United States commonly receive priority for their nonprimary organ over many individuals who need that organ, which may undermine equity. The absence of standard criteria for MOT eligibility also enables large and unfair regional variation in MOT, such as simultaneous liver-kidney transplantation. Unfortunately, MOT may also undermine utility (optimal patient and graft survival) in circumstances where providing multiple organs to one person fails to achieve the greater collective benefit attained by providing transplants to multiple people. Policy reforms should include the adoption of minimal clinical criteria for MOT candidacy with the attendant goal of decreasing regional variation in MOT. In the future, these minimal criteria can be revised to accommodate new research about which patients derive the most benefit from MOT. Incentives to perform MOT should also be reduced, such as by including MOT outcomes in center-specific reports. These reforms run the risk that the transplant community could be perceived as abandoning MOT candidates, but offer an opportunity to align transplant practice and ethical principles.

Abstract
Transplantation of the whole vascularized pancreas can provide insulin secretion in patients with insulin-dependent, type 1 diabetes mellitus (T1D). It restores euglycemia in most patients, with the potential to impact the chronic diabetic complications and quality of life. Pancreas transplantation (PT) is presently controversial for type 2 diabetes mellitus (T2D). For those patients with severe glycemic dysregulation, T2D can be associated with the same life-threatening sequelae as T1D such as severe hypoglycemia and kidney failure that could be corrected by pancreas (and kidney) transplantation. Thus, clinical indications and patient selection criteria are very important. This chapter will review the current status of PT for T2D and discuss the options and evolution of transplant perspectives.

Abstract
For patients with diabetes and progressive chronic kidney disease, kidney transplantation is the optimal mode of renal replacement therapy, with or without a pancreas transplant. Additional benefits of pancreas transplant have become increasingly apparent due to advances in surgical outcomes and immunosuppression, and may be reasonably considered even in selected patients with type 2 diabetes. In general, pancreas transplantation is associated with long-term survival advantages despite an increased short-term morbidity and mortality risk. This is true with simultaneous pancreas kidney transplantation or pancreas after kidney transplantation compared to kidney transplantation alone, regardless of kidney donor status (living or deceased). Individual patient preferences, comorbidities, and expected waiting time influence selection of transplant modality, rather than a clear survival benefit of one strategy versus the other. In selected patients with type 2 diabetes, recent outcomes data support cautious utilization of simultaneous pancreas kidney transplantation when a living kidney donor transplant is not an option. The purpose of this review is to summarize current data regarding kidney and pancreas transplant treatment options in patients with both type 1 and 2 diabetes and the influence of current organ allocation policies to better understand the advantages and disadvantages of each of these strategies.

Abstract
CONTEXT Since 2006 a relevant number of therapeutical algorithms for the management of type 2 diabetes have been proposed, generating a lively debate in the scientific community, particularly on the ideal timing for introduction of insulin therapy and on which drug should be preferred as add-on therapy in patients failing to metformin. At the moment, there is no real consensus. The aim of the present review is to summarize established knowledge and areas for debate with respect to insulin therapy in type 2 diabetes. EVIDENCE ACQUISITION In type 2 diabetic patients, insulin represents a therapy with a long and well-established history, but, considering the modern insulin therapy, several points must be carefully examined. The role played by the introduction of insulin analogues, the choice of insulin regimens, the ongoing debate on insulin and cancer, the cardiovascular effects of insulin, the role of insulin on β-cell protection and the actual clinical perspective in the treatment of the disease. Nevertheless, still many exciting expectations exist: the new insulin analogues, the technological options, the inhaled and oral insulin and the issue of transplantation. CONCLUSIONS Although insulin is the more potent hypoglicemic agent, the availability of a wider spectrum of therapeutic agents, many of which are better tolerated than insulin, has reduced the field of application for insulin treatment; presently, insulin is used only in those who cannot maintain an adequate glycemic control with other drugs. Furthermore, a lively research activity is currently ongoing, in order to make insulin therapy even safer and simpler for patients.

Abstract
The life expectancy of patients with type 1 diabetes mellitus is inferior to that of patients with some malignancies. Simultaneous pancreas-kidney transplantation is the procedure providing the best survival results among all options of renal replacement therapy. The operative techniques and immunosuppresion have been standardized in the last decade. Although the number of transplantable organs falls behind the need, simultaneous pancreas-kidney transplantation is the method of choice for the eligible patients. The results of the two Hungarian simultaneous pancreas-kidney transplantation programs are in accordance with data published in the international literature.

Abstract
Obesity is a worldwide epidemic leading to severe comorbidity that damages end-organ function. Overall transplant outcomes in this population are inferior to those in nonobese patients. Large population studies show decreased patient and graft survival in obese kidney transplant patients. Despite the poorer outcomes, kidney transplantation is considered because of the survival benefit as compared with the wait-listed dialysis patients. In liver transplantation, the benefit to transplantation as compared with remaining on the list is obvious, as there is no viable liver dialysis at this time. Obesity in potential organ donors impacts both medical and surgical issues. Obesity-related kidney disease affects both the remaining and transplanted kidney. Pancreas donor organs are associated with decreased early graft survival. Liver donor organs with significant steatosis lead to an increased risk for delayed or nonfunction of the organ. Immunosuppressive drugs with variable lipophilicity and altered volume of distribution can greatly affect the therapeutic usefulness of these drugs. Transplant candidates benefit from a multidisciplinary team approach to their care. As the epidemic progresses and less-invasive treatments for metabolic surgery evolve, we are likely to require more patients to lose weight prior to transplantation as we continue to strive for improved outcomes.

Abstract
Diabetes mellitus is the most common etiology for end stage renal disease (ESRD) worldwide and in the United States. The incidence of morbidity and mortality is higher in diabetic patients with ESRD due to increased cardiovascular events. Patients with type 2 diabetes who receive a renal allograft have a higher survival rate compared with patients who are maintained on chronic hemodialysis therapy, but there is scarcity of data on long-term graft outcomes. Most recently the development of new onset diabetes after transplantation (NODAT) poses a serious threat to patient and allograft survival. Pre-emptive transplantation and the use of living donors have improved overall survival. In addition, critical management of glucose, blood pressure, and cholesterol are some of the factors that can help minimize adverse outcomes in both patients with pre-existing diabetes and patients who develop NODAT. Future clinical trials are warranted to improve therapeutic medical management of these patients thus influencing graft attrition.
