Simultaneous pancreas kidney transplantation

PROBLEM: Hyperkalemia is a serious condition among intra-abdominal transplant recipients, and the safety and efficacy of sodium-zirconium cyclosilicate (SZC) for its management during the early post-transplant period are not well-established. METHODS: Adults who received at least one 10-g dose of SZC within 14 days after an intra-abdominal transplant between January 2020 and July 2022 were included in our study. The primary outcome was the change in potassium (K+) levels following the first SZC dose...

Ectopic variceal bleeding is a potentially under recognized source of gastrointestinal (GI) hemorrhage. While vascular complications following pancreatic transplant are relatively common, the development of symptomatic ectopic venous varices has rarely been reported. We report two patients with a remote history of simultaneous kidney pancreas transplant (SPK) presenting two decades after transplant with an occult GI bleed. In both cases, a lengthy diagnostic course was required. The varices were treated with coil embolization via transhepatic approach...

The number of solid organ pancreas transplants performed in the United States has declined over the past two decades despite improving outcomes and the known benefits associated with this procedure. Although the reasons are multifactorial, high rates of deceased donor pancreata nonrecovery and nonuse have at least in part contributed to the reduction in pancreas transplant activity. The pancreas has higher nonrecovery and nonuse rates compared to the kidney and liver because of more stringent donor selection criteria, particularly with respect to donor age and body mass index, although even marginally inferior donor pancreata likely still benefit some patients compared to alternative therapies...

Common variable immune deficiency (CVID) is a primary immunodeficiency disorder, with hypogammaglobulinemia and increased susceptibility to recurrent infections, autoimmune disorders, granulomatous diseases and malignancy. Among the solid organ transplant (SOT) recipient population, those with primary immunodeficiency disorders under chronic immunosuppression therapy can theoretically be at higher risk of atypical infections, autoimmune complications and disease recurrence with suboptimal long term graft survival, but literature is scarce...

Type 1 diabetes mellitus (T1DM) is one of the important causes of chronic kidney disease (CKD) and end-stage renal failure (ESRF). Even with the best available treatment options, management of T1DM poses significant challenges for cli nicians across the world, especially when associated with CKD and ESRF. Substantial increases in morbidity and mortality along with marked rise in treatment costs and marked reduction of quality of life are the usual consequences of onset of CKD and progression to ESRF in patients with T1DM...

Pancreatic graft thrombosis (PAT) is a major surgical complication, potentially leading to graft loss. The recently proposed Cambridge Pancreas Allograft Thrombosis (CPAT) grading system provides diagnostic, prognostic and therapeutic recommendations. The aim of the present study was to retrospectively assess computed tomography angiography (CTA) examinations performed routinely in simultaneous pancreas-kidney (SPK) recipients to implement the CPAT grading system and to study its association with the recipients' outcomes...

BACKGROUND: BK polyomavirus (BKV) infection is a common complication of kidney transplantation. While BKV has been described in non-kidney transplant recipients, data are limited regarding its epidemiology and outcomes in pancreas transplant recipients. METHODS: We conducted a retrospective cohort study of adults who underwent pancreas transplantation from 2010-2020. The primary outcome was BKV DNAemia. Secondary outcomes were estimated glomerular filtration rate (eGFR) reduction by 30%, eGFR < 30 mL/min/1...

BACKGROUND: Whole pancreas transplantation provides durable glycemic control and can improve survival rate; however, it can carry an increased risk of surgical complications. One devastating complication is a duodenal leak at the site of enteroenteric anastomosis. The gastroduodenal artery (GDA) supplies blood to the donor duodenum and pancreas but is commonly ligated during procurement. Since we have not had expressive changes in pancreatic back table surgical techniques in the recent decades, we hypothesized whether back table GDA reconstruction, improving perfusion of the donor duodenum and head of the pancreas, could lead to fewer surgical complications in simultaneous pancreas-kidney (SPK) transplants...

The purpose of pancreas or islet transplantation is to restore glycemic control in order to mitigate diabetes-related complications and prevent severe hypoglycemia. Complications from chronic pancreas allograft rejection may lead to transplantectomy, even when the endocrine function remains preserved. We present first evidence of a successful HLA incompatible islet re-transplantation with islets isolated from a rejecting pancreas allograft after simultaneous kidney pancreas transplantation. The pancreas allograft was removed because of progressively painful pancreatic panniculitis from clinically uncontrolled chronic rejection...

INTRODUCTION: Kidney transplant recipients (KTR) have a three-to-four-fold increased risk of developing urothelial carcinoma (UC) compared to the general population. BK polyoma virus (BKV) infection is known to affect approximately 15% of KTR. In vitro models support a potential pathogenic role for BKV in the development of UC. We describe a series of UC in kidney transplant recipients. METHODS: Electronic patient records were searched to identify KTR with UC who had undergone kidney only or simultaneous kidney and pancreas transplantation in a single UK center between 2009 and 2015...

BACKGROUNDS: It is not known which of the 5 components of the Fried frailty score have the most predictive value for outcomes in simultaneous pancreas-kidney transplant (SPK) and solitary pancreas transplant (SPT) recipients. METHODS: In this study, we sought to investigate the association between pretransplant overall frailty and individual frailty components, with posttransplant outcomes among SPK and SPT recipients. Outcomes of interest were length of stay, kidney delayed graft function (K-DGF), readmission within 30 d after discharge, cardiovascular events, acute rejection, pancreas death-censored graft failure (DCGF), kidney DCGF, and death...

OBJECTIVES: Pancreas transplant can have serious complications requiring salvage pancreatectomy, and surgical approaches should be carefully considered, with jejunal or ileal anastomoses most often employed. The jejunum may reduce gastrointestinal disturbance, whereas the ileum is more immunogenic. Proximal gastrointestinal anastomoses pose challenges with salvage pancreatectomy and creation of high-output stoma, often in the context of end-stage renal failure. Here, we compared outcomes between these techniques...

A 52-year-old man with a history of type 1 diabetes mellitus with diabetic nephropathy who underwent simultaneous pancreas-kidney transplant over a decade ago presented with small bowel obstruction and was found by enteroscopy to have a carpeted lesion encompassing the small bowel anastomosis in the region of the donor pancreas. As endoscopic mucosal resection was impracticable because of technical limitations, the patient was referred to transplant surgical team for surgical exploration and ultimately required organ resection...

INTRODUCTION: Weight gain after pancreas transplant is a poorly understood phenomenon thought to be related to increased posttransplant insulin production, immunosuppressive medications, and appetite changes. No study has investigated the effect of increased exocrine secretion posttransplant. AIMS AND HYPOTHESIS: We hypothesized that exocrine function, measured by fecal elastase-1 (FE-1), was normal posttransplant and not correlated with weight gain. Our primary aim was to investigate changes in FE-1 levels with pancreas transplantation and to correlate this with weight gain...

IMPORTANCE: Planning for future resurgences in SARS-CoV-2 infection is necessary for providers who care for immunocompromised patients. OBJECTIVE: to determine factors associated with COVID-19 disease severity in immunosuppressed children. DESIGN: a case series of children with solid organ transplants diagnosed with SARS-CoV-2 infection between 15 March 2020 and 31 March 2023. SETTING: a single pediatric transplant center...

INTRODUCTION: Pancreas transplantation is currently the only treatment that can re-establish normal endocrine pancreatic function. Despite all efforts, pancreas allograft survival and rejection remain major clinical problems. The purpose of this study was to identify features that could signal patients at risk of pancreas allograft rejection. METHODS: We collected 74 features from 79 patients who underwent simultaneous pancreas-kidney transplantation (SPK) and used two widely-applicable classification methods, the Naive Bayesian Classifier and Support Vector Machine, to build predictive models...

Ectopic peritransplant varicosis represents an uncommon cause of late-onset gastrointestinal (GI) bleeding after simultaneous pancreas and kidney transplantation (SPK). We report on a 53-year-old female patient who suffered from recurrent upper GI bleeding seven years after SPK with persistent graft function. Upper endoscopy revealed perianastomotic angiodysplasias, treated by clipping and Argon-Plasma-Coagulation. Repeated endoscopy showed no signs of anastomotic ulcer. With persistent symptoms, computed tomography and angiography revealed extensive ectopic varicosis around the pancreas and duodenal graft...
