Evaluating the Impact and Rationale of Race-Specific Estimations of Kidney Function: Estimations from U.S. NHANES, 2015-2018.

Background: Standard equations for estimating glomerular filtration rate (eGFR) employ race multipliers, systematically inflating eGFR for Black patients. Such inflation is clinically significant because eGFR thresholds of 60, 30, and 20 ml/min/1.73m guide kidney disease management.

Impact of Low-Dose Fluconazole on Tacrolimus Dosing in Renal Transplant.

Background: The interaction between azole antifungal therapy and immunosuppressant tacrolimus (TAC) is a barrier to use.

Objective: This study quantified the drug interaction between low-dose fluconazole (LDF) and TAC to determine the appropriate TAC dose adjustment when used concurrently in renal transplant recipients.

Methods: We conducted a single-center retrospective chart review of renal transplant patients 18 years who received LDF or nystatin (NYS), and TAC.

Identifying a Kidney Transplant Recipient COVID Phenotype to Aid Test Utilization in the Setting of Limited Testing Availability-Does One Exist?

The high morbidity and mortality of COVID-19 in immunocompetent patients raises significant concern for immunosuppressed kidney transplant recipients (KTRs). This level of concern, both on the part of the KTRs and transplant professionals, is heightened by a lack of prior knowledge on how Severe Acute Respiratory Syndrome 2 virus (SARS-CoV-2) may manifest differently in immunosuppressed patients. Characterizing how KTRs may present differently than the general population would allow for more targeted and timely evaluation and treatment of KTRs with COVID-19 infection.

The Role of the General Nephrologist in Evaluating Patients for Kidney Transplantation: Core Curriculum 2020.

Transplantation is the preferred modality of replacement therapy for most patients with kidney failure. In the United States, more than 3,000 new patients are registered each month on the kidney transplant waiting list for this life-saving therapy. A potential kidney transplant recipient's evaluation typically begins with a referral by the general nephrologist to a transplantation center.

Graft-Versus-Host Disease After Pancreatic Transplantation.

Graft-versus-host disease (GVHD) is a common complication of hematopoietic stem cell transplantation but can rarely occur after solid organ transplants. Small bowel and liver transplants are typically implicated, but solid organ transplant-associated GVHD has also been associated with other organs. We present a 40-year-old diabetic woman who underwent renal followed by pancreatic transplantation over a span of 21 months and ultimately developed acute classic GVHD.

New Organ Allocation System for Combined Liver-Kidney Transplants and the Availability of Kidneys for Transplant to Patients with Stage 4-5 CKD.

A new proposal has been created for establishing medical criteria for organ allocation in recipients receiving simultaneous liver-kidney transplants. In this article, we describe the new policy, elaborate on the points of greatest controversy, and offer a perspective on the policy going forward. Although we applaud the fact that simultaneous liver-kidney transplant activity will now be monitored and appreciate the creation of medical criteria for allocation in simultaneous liver-kidney transplants, we argue that some of the criteria proposed, especially those for allocating a kidney to a liver recipient with AKI, are too liberal.

Delayed Graft Function Phenotypes and 12-Month Kidney Transplant Outcomes.

Background: Ischemia-reperfusion injury (IRI) leading to delayed graft function (DGF), defined by the United Network for Organ Sharing as dialysis in the first week (UNOS-DGF), associates with poor kidney transplant outcomes. Controversies remain, however, about dialysis initiation thresholds and the utility for other criteria to denote less severe IRI, or slow graft function (SGF).

Methods: Multicenter, prospective study of deceased-donor kidney recipients to compare UNOS-DGF to a definition that combines impaired creatinine reduction in the first 48 hours or greater than 1 dialysis session for predicting 12-month estimated glomerular filtration rate (eGFR).

Duration of prophylaxis against fungal infection in kidney transplant recipients.

Objective: To compare the efficacy of 2 strategies that use nystatin to prevent thrush and Candida esophagitis in kidney transplant recipients.

Methods: A retrospective chart review was conducted of adult kidney transplant recipients at our center, where the protocol for prophylaxis against fungal infection was changed in March 2013. Before the protocol change, kidney transplant recipients received nystatin for 1 month (before group) and after the change they received nystatin for the duration of admission (after group).

Oncologic issues and kidney transplantation: a review of frequency, mortality, and screening.

Kidney transplant recipients are at increased risk for development of malignancy compared with the general population, and malignancies occur at an earlier age. This increased risk, as expressed by the standard incidence ratio (SIR), varies widely, but it is highest in malignancies triggered by oncogenic viruses. For other cancers, this increased risk is the direct consequence of immunosuppressants promoting tumor growth and lowering immune system tumor surveillance.

A one-day centralized work-up for kidney transplant recipient candidates: a quality improvement report.

Background: Waiting time for a kidney transplant is calculated from the date the patient is placed on the UNOS (United Network for Organ Sharing) waitlist to the date the patient undergoes transplant. Time from transplant evaluation to listing represents unaccounted waiting time, potentially resulting in longer dialysis exposure for some patients with prolonged evaluation times. There are established disparities demonstrating that groups of patients take longer to be placed on the waitlist and thus have less access to kidney transplant.

Should living kidney donor candidates with impaired fasting glucose donate?

As the kidney transplant waiting list grows, the willingness of transplant centers to accept complex donors increases. Guidelines for the evaluation of living kidney donors exist but do not provide clear guidance when evaluating the complex donor. Although few transplant centers will approve donor candidates with impaired glucose tolerance and most, if not all, will deny candidates with diabetes, many will approve candidates with impaired fasting glucose (IFG).

Kidney transplantation and HIV: does recipient privacy outweigh the donor's right to information?

Background And Objectives: There exists an inherent conflict between a kidney donor's right to know key aspects of a recipient's medical history and specific disease, such as HIV, where federal and state statues protect this information. The authors of the live organ donor consensus group expressly stated the principal of a donor's right to recipient information. This information includes the risks and benefits of not only the donation procedure, but also the risks, benefits, and alternative treatment options of the recipient.
