Delayed Graft Function in Kidney Retransplantation: United Network for Organ Sharing Data With Linked Primary and Retransplant.

Introduction: There are several articles exploring the risk factors for primary delayed graft function (DGF). However, current literature does not include many resources on the risk factors for DGF when it is a recipient's second kidney transplant or look at short-term graft and patient survival of DGF retransplants.

Methods: United Network for Organ Sharing data from January 2008 to June 2021 were analyzed.

Impact of Clotrimazole Fungal Prophylaxis on Tacrolimus Exposure in Kidney Transplant Recipients: A Retrospective Study.

Tacrolimus, an immunosuppressant prescribed to reduce the risk of organ rejection, is metabolized by cytochrome P450 and is a substrate for P-glycoprotein. Many medications affect tacrolimus concentrations, making it difficult to maintain exposure within its narrow therapeutic index. Clotrimazole troches, prescribed to posttransplant recipients immediately for the first 30 days for oral candidiasis prevention, are considered nonsystemic.

Endovascular Stenting of Portal Vein for Graft Rescue after a Pancreas Transplant Venous Graft Thrombosis: A Case Report.

Venous thrombosis of pancreas transplant allografts often leads to graft loss. It is an worrisome complication and difficult to treat, forming the most common nonimmunological cause of graft loss. Multiple risk factors have been implicated in the development of venous thrombosis of pancreas transplant.

De Novo Thrombotic Microangiopathy Immediately After Kidney Transplant in Patients Without Apparent Risk Factors.

Thrombotic microangiopathy refers to a spectrum of conditions that share a common underlying pathologic mechanism that result in endothelial damage and microangiopathic hemolytic anemia. De novo thrombotic microangiopathy after kidney transplant is often triggered by immunosuppressive drugs, and studies most often implicate calcineurin inhibitors and/or mammalian target of rapamycin inhibitors; however, muromonab and alemtuzumab also reportedly cause thrombotic microangiopathy. In addition, thrombotic microangiopathy may be triggered by acute antibody-mediated rejection and infections like cytomegalovirus and parvovirus.

Dialysis within 24 hours of transplant does not improve graft function.

Objectives: Grafts from extended criteria donors, donors after cardiac death, and elderly donors have an increased risk of delayed graft function, lower graft survival, longer hospital stay, higher costs, and increased medical sequelae. A modifiable risk factor for delayed graft function may be the performance of dialysis on the same day as renal transplant. We reviewed our institutional experience to determine whether dialysis performed within 24 hours of engraftment increased the incidence or length of delayed graft function.

Equal 3-Year Outcomes for Kidney Transplantation Alone in HCV-Positive Patients With Cirrhosis.

Kidney transplantation alone in clinically compensated patients with cirrhosis is not well documented. Current guidelines list cirrhosis as a contraindication for kidney transplantation alone. This is an Institutional Review Board-approved retrospective study.

Risk factors for renal allograft compartment syndrome.

Renal allograft compartment syndrome (RACS) is graft dysfunction secondary to intracompartment hypertension. The purpose of this study was to identify risk factors for RACS. We reviewed 7 cases of established RACS and all intra-abdominal placements of the kidney in order to include potential RACS.

Elimination of warm ischemia using the Ice Bag Technique does not decrease delayed graft function.

Background: Warm ischemic time (WIT) in kidney transplantation has significant effects on graft survival, function, and postoperative morbidity. We utilized the Ice Bag Technique (IBT) to determine if eliminating WIT would decrease the incidence and length of delayed graft function (DGF) in our cohort.

Methods: We conducted a prospective study of 150 kidney transplants.

No benefit when placing drains after kidney transplant: a complex statistical analysis.

Objectives: This paper sought to determine if there were an association between drain placement and the incidence of wound complications.

Materials And Methods: A single-center institutional review board-approved retrospective study between 2001 to 2008, comparing 680 kidney transplant patients who either had a drain placed or were left undrained. Linear regression modeling was used to adjust the risk factors between the groups.

The "July effect" does not have clinical relevance in liver transplantation.

In the beginning of the academic year, medical errors are often attributed to inexperienced medical staff. This potential seasonal influence on health care outcomes is termed the "July effect." No study has demonstrated the July effect in liver transplantation.

Satisfactory outcomes with usage of extended criteria donor (ECD) kidneys in re-transplant recipients.

Background: The use of extended criteria donor (ECD) kidneys have increased substantially and the benefit recognized in certain populations. Our institution has maintained a policy of aggressively utilizing ECD kidneys, even among those who have failed a previous transplant. Previous reports on the benefit of ECD in re-transplants have shown equivocal outcomes.

Evaluating safety and efficacy of rabbit antithymocyte globulin induction in elderly kidney transplant recipients.

Objectives: The optimal immunosuppression regimen for elderly kidney transplant recipients is poorly defined. We sought to evaluate the short-term efficacy and safety of thymoglobulin in geriatric recipients of deceased-donor kidneys.

Materials And Methods: A single-center, retrospective analysis was undertaken between elderly (≥ 65 years) (n=137) and nonelderly (n=276) kidney transplant recipients who received rabbit antithymocyte globulin induction and calcineurin inhibitor, mycophenolic acid, and prednisone maintenance.

Are hepatitis C-positive allografts in simultaneous pancreas-kidney transplantation underutilized?

Background: A recent review reported that recipient HCV infection had no significant impact on acute rejection rates or patient survival in SPKT but the utilization of HCV(+) organs was negligible. Using the UNOS database, we sought to determine utilization rates for HCV(+) allografts in Simultaneous Pancreas-Kidney Transplantation (SPKT.

Material/methods: The Organ Procurement and Transplant Network / United Network for Organ Sharing database was employed to obtain information regarding HCV(+) and HCV-negative (HCV(-)) SPKT recipients and the disposition of donor pancreata.

Soft tissue sarcoma at a dialysis access site in a transplant recipient.

Soft tissue sarcomas typically present as soft, painless masses on an extremity. Here, we present a patient with metastatic soft tissue sarcomas at his dialysis access site. This association with dialysis access has not been documented previously.

Early allograft biopsies performed during delayed graft function may not be necessary under thymoglobulin induction.

Objectives: Delayed graft function affects up to 50% of kidney transplant recipients. Some guidelines recommend surveillance biopsies beginning 7 days after engraftment. This may be unnecessary with anti-thymocyte globulin induction.

Operative start times and complications after kidney transplantation.

The worldwide focus on work hour regulations and patient safety has led to the re-examination of the merits of night-time surgery, including kidney transplantation. The risks of operating during nontraditional work hours with potentially fatigued surgeons and staff must be weighed against the negative effects of prolonged cold ischemic time with resultant graft compromise. The aim of this study was to evaluate the impact of performing renal transplantation procedures during evening versus day time hours.

Tc-99m-BrIDA hepatobiliary (HIDA) scan has a low sensitivity for detecting biliary complications after orthotopic liver transplantation in patients with hyperbilirubinemia.

Background: Tc-99m-BrIDA hepatobiliary scans are noninvasive tests for detecting biliary leaks and obstructions. However, there is low sensitivity and specificity in patients with hyperbilirubinemia. Biliary complications (BC) are the Achilles heel of orthotopic liver transplantation (OLT).

Severe hepatitis C virus recurrence is nearly universal after donation after cardiac death liver transplant.

Objectives: The rate of hepatitis C virus recurrence after donation after cardiac death liver transplant is not clearly defined.

Materials And Methods: This is a retrospective review of 39 donations after cardiac death-liver transplant recipients. Biopsies were performed at 6, 12, 24, and 36 months for all hepatitis C virus positive donation after cardiac death recipients.

Paraparesis caused by transarterial chemoembolization: A case report.

Transarterial chemoembolization (TACE) is an effective modality for the treatment of Hepatocellular Carcinoma. It is used to treat small tumors and to downstage large tumors to meet liver transplant criteria. TACE can be associated with multiple side effects, including fever, right upper quadrant pain, nausea, vomiting, hepatic failure, hepatic encephalopathy, cholecystitis and pancreatitis.

Cutaneous metastasis of pancreatic adenocarcinoma after kidney transplant: a case report and review of the literature.

Objectives: Pancreatic cancer is one of the most lethal human cancers. Each year in the United States, about 42 470 individuals are diagnosed with this condition, and 35 240 die, despite advances in imaging, medical treatment, and surgical intervention. Often, 80% to 90% of pancreatic cancers are diagnosed at the locally advanced or metastatic stage.

Horseshoe kidneys: an underutilized resource in kidney transplant.

Objectives: Although the number of patients awaiting renal transplant is rapidly increasing, the donor pool has remained relatively stable. Horseshoe kidneys, a common renal fusion anomaly, can provide a useful solution to the ever increasing gap between supply and demand.

Materials And Methods: These kidneys can be transplanted, en bloc, into a single recipient or divided and transplanted into 2 recipients.

Infrahepatic vena cavocavostomy, a modification of the piggyback technique for liver transplantation.

We describe our experience with a modification of the piggyback (PB) technique for orthotopic liver transplantation in which the donor infrahepatic vena cava is used as the venous outflow tract. From May 1997 to January 2006, a total of 109 cases using this technique were performed in 101 patients. Collected data included recipient demographics and diagnosis, warm ischemia time, use of venovenous bypass or temporary portacaval shunt and complications related to the venous outflow and graft, and patient survival.

Simvastatin-ezetimibe-induced hepatic failure necessitating liver transplantation.

Abstract Serum aminotransferase elevations are a commonly known adverse effect of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor (statin) therapy. However, hepatotoxic events have not been widely published with ezetimibe or the combination agent simvastatin-ezetimibe. We describe a 70-year-old Hispanic woman who developed fulminant hepatic failure necessitating liver transplantation 10 weeks after conversion from simvastatin 40 mg/day to simvastatin 10 mg-ezetimibe 40 mg/day.
