Abstract
BACKGROUND Early vascular complications following pancreatic transplantation are not uncommon (3%-8%). Typically, cross-sectional imaging is requested in response to clinical change. We instituted a change in protocol to request imaging pre-emptively to identify patients with thrombotic complications. METHODS In 2013, protocol computer tomography angiography (CTA) at days 3-5 and day 10 following pancreas transplantation was introduced. A retrospective analysis of all pancreas transplants performed at our institution from January 2001 to May 2019 was undertaken. RESULTS A total of 115 patients received pancreas transplants during this time period. A total of 78 received pancreas transplant without routine CTA and 37 patients with the new protocol. Following the change in protocol, we detected a high number of subclinical thromboses (41.7%). There was a significant decrease in invasive intervention for thrombosis (78.6% before vs 30.8% after, p = .02), and graft survival was significantly higher (61.5% before vs 86.1% after, p = .04). There was also a significant reduction in the number of graft failures (all-cause) where thrombosis was present (23.4% before vs 5.6% after, p = .02). Patient survival was unaffected (p = .48). CONCLUSIONS Implementation of early protocol CTA identifies a large number of patients with subclinical graft thromboses that are more amenable to conservative management and significantly reduces the requirement for invasive intervention.

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.

Abstract
Pancreas transplant recipients experience graft loss in spite of improvements in immunosuppressant therapies and diagnostic technologies. Therefore, a method to improve detection and management of acute rejection is needed. This longitudinal study investigated the usefulness of three biomarkers, granzyme B, perforin, and human leukocyte antigen-DR alpha (HLA-DR) measured by real-time PCR on peripheral blood mononuclear cells, for their ability to detect acute rejection and its resolution in 13 recipients of pancreas allograft. Data demonstrated that pre-transplant baseline expression of biomarkers decreased following the initiation of immunosuppression. Throughout follow-up (range 3-27 months), individuals without acute rejection episodes had little variation in their biomarker levels. Recipients with biopsy-proven rejection had a significant increase in the levels of biomarkers as early as five wk before clinical rejection diagnosis. Furthermore, all seven patients with biopsy-proven rejection demonstrated a decrease in the levels of granzyme B and perforin following the increased immunosuppression for the treatment of rejection. This is the first clinical serial measurement of biomarkers in recipients of pancreas transplants. The data demonstrate that upregulation of granzyme B, perforin, and HLA-DR in peripheral blood mononuclear cells are sensitive to changes in the immune environment and could possibly be used to identify those patients at higher risk of rejection.

Abstract
INTRODUCTION There is some controversy concerning the choice of best technique for drainage of exocrine secretions in pancreas transplantation. We compared patients with bladder drainage (BD) versus those with enteric drainage (ED). PATIENTS AND METHODS From March 1995 to September 2008, 118 patients (68 men and 50 women) of overall mean age of 37.8 +/- 7.8 years underwent pancreas transplantation. There were 109 simultaneous pancreas-kidney, and 9 pancreas after kidney procedures. Recipients were divided in a BD (n = 66 patients) and an ED group (n = 52). RESULTS Donor characteristics were similar in both groups. Thirty-two patients (48.5%) of the BD group versus none in the ED group experienced urinary tract infections (UTI; P < .001), and 16 patients (24.2%) BD versus 15 (29.4%) ED developed intraabdominal infections (P = NS). The overall rate of relaparotomies was 33.9% (n = 40): 34.8% (n = 23) in the BD versus 32.7% (n = 17) in the ED group (P = NS). Thirty patients (25.4%) lost their pancreas grafts: 21 (31.8%) in the BD group versus 9 (17.3%) in the ED group (P = .055). The acute rejection rates were 12.7%; namely, 15.2% in the BD versus 9.8% in the ED (P = NS). Three-year patient and graft survivals were equivalent in both groups: 96.1% and 65.3% in the BD versus 89.0% and 74.0% in the ED group, respectively (P = NS). CONCLUSIONS ED is a good alternative to BD for drainage of pancreatic graft exocrine secretions because both techniques have the same patient and graft survival, but BD is associated with a significantly higher rate of UTI and urologic complications.

Abstract
Diabetes mellitus (DM) is a major health problem worldwide, which affects 18.2 million individuals (6.3% of the population) in the United States. Currently, the prevalence of Type 1 DM in the United States is estimated to be 1,000,000 individuals, and 30,000 new cases are diagnosed each year. In addition to end-stage renal disease (ESRD), DM is associated with blindness, accelerated atherosclerosis, dyslipidemia, cardio- and cerebrovascular disease, amputation, poor quality of life, and overall lifespan reduction. It accounts for more than 160,000 deaths per year in the United States alone. In 2002, the annual national direct and indirect costs of Types 1 and 2 DM exceeded $130 billion, which included hospital and physician care, laboratory tests, pharmaceutical products, and patient workdays lost because of disability or premature death. Hyperglycemia alone or in concert with hypertension is the primary factor influencing the development of major diabetic complications. From 1990 to 2001, the number of existing ESRD cases to DM increased by more than 300%, while the rate per million populations increased from 167% to 491%. The number is expected to grow 10-fold by 2030 to 1.3 million accounting for 60% of ESRD population. To date, DM is the leading indication for transplantation and is the cause of ESRD in more than 40% of all transplant recipients each year.

Abstract
Background Combined kidney pancreas transplantation (PTx) evolved as excellent treatment for diabetic nephropathy. Infections remain common and serious complications. Methods 217 consecutive enteric drained PTxs performed from 1997 to 2004 were retrospectively analyzed with regard to bloodstream infection. Immunosuppression consisted of antithymocyteglobuline induction, tacrolimus, mycophenolic acid and steroids for the majority of cases. Standard perioperative antimicrobial prophylaxis consisted of pipercillin/tazobactam in combination with ciprofloxacin and fluconazole. Results One year patient, pancreas and kidney graft survival were 96.4%, 88.5% and 94.8%, surgical complication rate was 35%, rejection rate 30% and rate of infection 59%. In total 46 sepsis episodes were diagnosed in 35 patients (16%) with a median onset on day 12 (range 1–45) post transplant. Sepsis source was intraabdominal infection (IAI) (n = 21), a contaminated central venous line (n = 10), wound infection (n = 5), urinary tract infection (n = 2) and graft transmitted (n = 2). Nine patients (4%) experienced multiple episodes of sepsis. Overall 65 pathogens (IAI sepsis 39, line sepsis 15, others 11) were isolated from blood. Gram positive cocci accounted for 50 isolates (77%): Coagulase negative staphylococci (n = 28, i.e. 43%) (nine multi-resistant), Staphylococcus aureus (n = 11, i.e. 17%) (four multi-resistant), enterococci (n = 9, i.e. 14%) (one E. faecium). Gram negative rods were cultured in twelve cases (18%). Patients with blood borne infection had a two year pancreas graft survival of 76.5% versus 89.4% for those without sepsis (p = 0.036), patient survival was not affected. Conclusion Sepsis remains a serious complication after PTx with significantly reduced pancreas graft, but not patient survival. The most common source is IAI.

Abstract
Refractory disease occurs in 25% or more of adults with idiopathic (immune) thrombocytopenic purpura (ITP). Therapy to elevate the platelet count may be required in a proportion of these patients. Immunosuppressive agents such as prednisone, azathioprine, cyclophosphamide, and cyclosporin have been shown to be effective treatments in a proportion of patients with refractory ITP. A newer immunosuppressive medication, mycophenolate mofetil (MMF), has been used successfully with acceptable toxicity in solid organ transplant patients to reduce the risk of organ rejection. The goal of this study was to determine whether MMF is an effective treatment for refractory ITP. Efficacy, defined as a sustained platelet increase to a level greater than 50 x 10(9)/L, was seen in 7 of 18 patients with refractory ITP. Three of these 7 patients have had intermittent thrombocytopenic episodes while continuing the medication. No severe toxicity was seen, although two of the 18 patients discontinued MMF within the first month of treatment because of side effects, i.e., headache. In summary, MMF may be a useful component of a combination protocol but does not appear to be highly effective as sole therapy in patients with refractory ITP. The data suggests that response rates to MMF may be higher in patients who have had a shorter duration of their ITP.

Abstract
While pancreas transplantation has evolved within two decades from a frustrating and poorly-accepted therapeutic option to a highly successful procedure, the respective benefits of the successive surgical and immunosuppressive developments have remained unclear. The aim of this study was to determine using an evidence-based methodology, which novel approaches have contributed to the current results and whether pancreas transplantation is cost-effective. Out of 2481 articles, 102 analyzed either surgical or immunosuppressive aspects of pancreas transplantation. Urological complications were more frequent in bladder over enteric drainage (range: 62-63% vs. 12-20%, p = 0.0001), but without significant difference in patient or graft survival. Portal drainage was associated with a trend toward fewer complications and better hyperinsulinemia control over systemic drainage in retrospective studies. Immunosuppression combining induction therapy, a calcineurin inhibitor, mycophenolate mophetil (MMF) and corticosteroids were associated with a 40% decreased incidence of rejection (p = 0.01) and an increase in graft survival above 90% at 1 year (p < 0.05). Pancreas transplantation is highly cost-effective compared to conservative alternatives. We conclude that despite a paucity of large studies, enteric drainage should be recommended but the benefits of portal venous drainage remain debated. Quadruple immunosuppression protocols including induction therapy should be the standard regimen.

Abstract
BACKGROUND Belzer solution is considered to be the best preservation media used for pancreas transplantation; however, its high cost accounts for approximately 14.5% of all resources allocated by the Brazilian government toward each pancreatic transplant. The objective of the present study was to test a reduction of Belzer solution during pancreas harvest, thereby lowering procedural cost. METHODS The patients received pancreas-kidney transplantations during the period from January 2003 to August 2004. Patients were divided into two groups. Patients assigned to Group A (n=30) received only Belzer solution (2 L through the aorta artery), whereas patients in Group B (n=16) were perfused first with 1 L of Eurocollins solution followed by 1 L of Belzer solution. The two groups were assessed for differences in the following clinical parameters: the need for insulin replacement or antifungal and anticytomegalovirus treatment, pancreatitis, acute cellular rejection, graft vascular thrombosis, fistulas, intra-abdominal collection, graft loss, deaths, pancreatic ischemia time, and average hospitalization time. RESULTS No statistically significant differences were observed in any of the parameters analyzed (P<0.05). The use of Eurocollins solution, followed by Belzer solution during pancreas harvesting, did not result in differences in graft survival or functionality, postsurgical complications, or patient survival and hospitalization time, when compared to the use of Belzer solution alone. CONCLUSIONS Perfusion with 1 L of Eurocollins solution followed by 1 L of Belzer solution during pancreas harvesting seems to be a simple and efficient alternative for reducing the costs of the harvesting process.

Abstract
BACKGROUND Pancreas transplantation (PTx) with portal-enteric drainage (PED) has been associated with difficulties in respect to arterial anastomosis and graft accessibility for percutaneous biopsy. We describe a new technique that circumvents these difficulties. METHODS Between April 2001 and April 2004, a total of 113 recipients were scheduled for PTx with PED. The superior mesenteric vein was approached from the right retroperitoneal aspect instead of from the anterior transmesenteric route. The pancreas graft was eventually placed in the right retroperitoneal space, being covered by the ascending colon and its mesentery. RESULTS One hundred ten (97.3%) PTx were performed as planned. Systemic venous effluent was preferred in three patients because of incidental diagnosis of liver cirrhosis during surgery (n=1) and severe obesity (body mass index>35 kg/m2) (n=2). The Y iliac artery graft was kept as short as possible, and arterial anastomosis was always performed with ease. After a mean follow-up period of 21.2+/-19.9 months, the relaparotomy rate was 13.6%. No patient died after repeat surgery, and none required multiple relaparotomies. Overall, 10 grafts were lost because of acute rejection (n=3), chronic rejection (n=2), venous thrombosis (n=2), recipient death (n=2), and late (6-month) arterial thrombosis (n=1). One-year patient and graft survival were 98.1% and 90.7%, respectively. CONCLUSIONS Our data confirm that PTx with PED is not associated with an increased risk. The technique described has distinctive technical advantages and should be included in the repertoire of PTx.

Abstract
OBJETIVO: Analisar o perfil dos principais centros de transplantes do Brasil, quanto às opções técnicas no transplante de pâncreas. MÉTODO: Foi encaminhado um questionário por correio eletrônico (email) para um membro de cada equipe de 12 centros de transplante do Brasil, com casuística mínima de um transplante de pâncreas. O questionário continha 10 perguntas, abordando aspectos controversos e não padronizados. RESULTADOS: A maioria dos centros (90,9%) utiliza incisão mediana. O órgão de escolha a ser implantado primeiro foi principalmente o rim, em 63% dos centros. Em relação à drenagem venosa, 90,9% utilizam a drenagem sistêmica. A ligadura da veia ilíaca interna é realizada em 54,5% dos centros. A maioria dos centros (90,9%) utiliza a drenagem entérica para transplante combinado pâncreas-rim. Para o transplante de pâncreas isolado, apenas cinco centros responderam, sendo que dois utilizam a drenagem entérica e três a vesical. A utilização de dreno na cavidade abdominal ocorre em 63% dos centros. Em 72,7% dos centros é realizada algum tipo de indução na imunossupressão para o transplante combinado pâncreas-rim, sendo a imunossupressão básica a associação de tacrolimus (FK506), micofenolato mofetil (MMF) e corticóide. A antibioticoprofilaxia é realizada por todos os centros e profilaxia para fungos é realizada por seis centros (54,5%). Oito centros (72,7%) utilizam algum tipo de profilaxia para trombose vascular, em esquemas diversos. CONCLUSÃO: Existem diversos caminhos técnicos na condução do transplante pancreático. A falta de padronização dificulta a análise e a comparação dos resultados. Apesar dessa heterogeneidade das equipes, observamos uma tendência para a realização de incisão mediana, drenagem venosa sistêmica e exócrina entérica, com a utilização de algum tipo de profilaxia para trombose vascular nos transplantes combinados pâncreas-rim.

Abstract
BACKGROUND Recent improvements in simultaneous pancreas-kidney transplantation (SPK) and the striking decrease in acute rejection lead us to focus on the effects of long-term immunosuppression. AIM OF THIS STUDY Evaluation of a policy of steroid withdrawal and tailored immunosuppression in pancreas-kidney patients treated in a single center. METHODS review of the clinical charts in 9 SPK recipients (male/female = 5/4, median age 41 years, median follow-up 42 months), by the same operator, under supervision of the two usual caregivers. Therapeutic protocols. Induction phase: all patients received mycophenolate mophetil (starting dose: 2 grams), tacrolimus and steroids, 8 received Simulect, 1 received thymoglobulins. Maintenance therapy was slowly reduced, with the goal of steroid withdrawal. RESULTS The therapeutic adjustments were mainly determined by two almost opposing elements: 1. Rapid adjustments in the case of side-effects (gastrointestinal problems, infections and neoplasia); 2. Slow tapering off in the case of good organ function. On the other hand, a switch to cyclosporine A and to rapamycine was considered in the case of chronic organ malfunction. By these means, over a median of 42 months follow-up, steroid withdrawal was slowly obtained in 6/9 patients (at a median time of 25 months). CONCLUSIONS Within the limits of this small-scale study, a tailored immunosuppressive policy allows at least some "positively selected" patients to reach the "dream" of steroid withdrawal after SPK.

Abstract
Diabetes is a leading cause of morbidity and mortality worldwide. Complications of diabetes including renal failure, retinopathy, neuropathy, and cardiovascular disease limit both survival and quality of life. Pancreatic transplantation can restore euglycemia thereby stabilizing or even reversing secondary complications of diabetes as well as improving quality of life particularly in patients with labile diabetes. Recent evidence also shows an improved survival in diabetic patients that undergo pancreatic transplantation when combined with a kidney transplant. Pancreatic transplantation should more properly be referred to as beta cell replacement as the field today encompasses both whole organ and islet cell transplantation. We have outlined herein the indications and contraindications to islet or whole organ pancreas transplantation and we have described periprocedure care and short- and long-term prognosis.

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
OBJECTIVE To compare outcomes in recipients of expanded criteria donor (ECD) versus standard criteria donor (SCD) kidneys at a single center using a standardized approach with similar immunosuppression. SUMMARY BACKGROUND DATA Expanded criteria deceased organ donors (ECD) are a source of kidneys that permit more patients to benefit from transplantation. ECD is defined as all deceased donors older than 60 years and donors older than 50 years with 2 of the following: hypertension, stroke as the cause of death, or pre-retrieval serum creatinine (SCr) greater than 1.5 mg/dl. METHODS We retrospectively studied 90 recipients of adult deceased donor kidneys transplanted from October 1, 2001 to February 17, 2003, including 37 (41%) from ECDs and 53 (59%) from SCDs. ECD kidneys were used by matching estimated renal functional mass to recipient need, including the use of dual kidney transplants (n = 7). ECD kidney recipients were further selected on the basis of older age, HLA-matching, low allosensitization, and low body mass index. All patients received a similar immunosuppressive regimen. Minimum follow up was 9 months. RESULTS There were significant differences in donor and recipient characteristics between ECD and SCD transplants. Patient (99%) and kidney graft survival (88%) rates and morbidity were similar between the 2 groups, with a mean follow-up of 16 months. Initial graft function and the mean 1-week and 1-, 3-, 6-, 12-, and 18-month SCr levels were similar among groups. CONCLUSIONS The use of ECD kidneys at our center effectively doubled our transplant volume within 1 year. A systematic approach to ECD kidneys based on nephron mass matching and nephron sparing measures may provide optimal utilization with short-term outcomes and renal function comparable to SCD kidneys.
