Interplay of Donor-Recipient Relationship and Donor Race in Living Liver Donation in the United States.

Introduction: Living liver donation improves survival of end-stage liver disease (ESLD) patients. Yet, it continues to represent a small proportion of United States (U.S.

Seasonal Patterns of Living Kidney Donation in the United States From 1995 to 2019.

Background: The number of living kidney donors in the United States has declined since 2005, with variations based on the donor-recipient relationship. The reasons for this decline are unclear, and strategies to mitigate declined donations remain elusive. We examined the change in donor number monthly (within-year) versus annually (between-years) to inform potentially modifiable factors for future interventions.

Donor Perceptions and Preferences of Telemedicine and In-Person Visits for Living Kidney Donor Evaluation.

Introduction: Living kidney donor evaluation is a lengthy and complex process requiring in-person visits. Access to transplant centers, travel costs, lost wages, and dependent care arrangements are barriers to willing donors initiating evaluation. Telemedicine can help streamline and epedite the evaluation process.

Kidney function assessment in the geriatric population.

Purpose Of Review: Kidney function declines with normal aging. But it also declines with the progression of some diseases. This review calls for a more nuanced interpretation of kidney function in the geriatric population, who may have frailty and comorbidities.

Living kidney donors with HIV: experience and outcomes from a case series by the HOPE in Action Consortium.

Background: Living kidney donation is possible for people living with HIV (PLWH) in the United States within research studies under the HIV Organ Policy Equity (HOPE) Act. There are concerns that donor nephrectomy may have an increased risk of end-stage renal disease (ESRD) in PLWH due to HIV-associated kidney disease and antiretroviral therapy (ART) nephrotoxicity. Here we report the first 3 cases of living kidney donors with HIV under the HOPE Act in the United States.

Association of Potentially Inappropriate Medication Classes with Mortality Risk Among Older Adults Initiating Hemodialysis.

Background And Objective: Older adults initiating dialysis have a high risk of mortality and that risk may be related to potentially inappropriate medications (PIMs). Our objective was to identify and validate mortality risk associated with American Geriatrics Society Beers Criteria PIM classes and concomitant PIM use.

Methods: We used US Renal Data System data to establish a cohort of adults aged ≥ 65 years initiating dialysis (2013-2014) and had no PIM prescriptions in the 6 months prior to dialysis initiation.

Changing landscape of living kidney donation and the role of telemedicine.

Purpose Of Review: There has been a decline in living kidney donation over the last two decades. Donors from low-income families or racial/ethnic minorities face greater disproportionate geographic, financial, and logistical barriers to completing lengthy and complex evaluations. This has contributed to the decreased proportion of these subgroups.

Telemedicine services for living kidney donation: A US survey of multidisciplinary providers.

Individuals considering living kidney donation face geographic, financial, and logistical challenges. Telemedicine can facilitate healthcare access/care coordination. Yet difficulties exist in telemedicine implementation and sustainability.

Long-term kidney function and survival in recipients of allografts from living kidney donors with hypertension: a national cohort study.

Allografts from living kidney donors with hypertension may carry subclinical kidney disease from the donor to the recipient and, thus, lead to adverse recipient outcomes. We examined eGFR trajectories and all-cause allograft failure in recipients from donors with versus without hypertension, using mixed-linear and Cox regression models stratified by donor age. We studied a US cohort from 1/1/2005 to 6/30/2017; 49 990 recipients of allografts from younger (<50 years old) donors including 597 with donor hypertension and 21 130 recipients of allografts from older (≥50 years old) donors including 1441 with donor hypertension.

Telemedicine in the Care of Kidney Transplant Recipients With Coronavirus Disease 2019: Case Reports.

Kidney transplant recipients who develop symptoms consistent with coronavirus disease 2019 (COVID-19) are bringing unique challenges to health care professionals. Telemedicine has surged dramatically since the pandemic in effort to maintain patient care and reduce the risk of COVID-19 exposure to patients, health care workers, and the public. Herein we present reports of 3 kidney transplant recipients with COVID-19 who were managed using telemedicine via synchronous video visits integrated with an electronic medical record system, from home to inpatient settings.

Outcome implications of benzodiazepine and opioid co-prescription in kidney transplant recipients.

The outcomes of benzodiazepine and opioid co-prescription are not well-defined in transplant populations. We examined linked national transplant registry and pharmaceutical records to characterize benzodiazepine and opioid use in the years before and after transplant in large US cohort of kidney transplant recipients (2007-2016; N = 98 620), and associations (adjusted hazard ratio, aHR ) with death and graft failure. Among the cohort, 15.

Benzodiazepines, Codispensed Opioids, and Mortality among Patients Initiating Long-Term In-Center Hemodialysis.

Background And Objectives: Mortality from benzodiazepine/opioid interactions is a growing concern in light of the opioid epidemic. Patients on hemodialysis suffer from a high burden of physical/psychiatric conditions, which are treated with benzodiazepines, and they are three times more likely to be prescribed opioids than the general population. Therefore, we studied mortality risk associated with short- and long-acting benzodiazepines and their interaction with opioids among adults initiating hemodialysis.

Long-term renal function in living kidney donors with simple renal cysts: A retrospective cohort study.

Simple (Bosniak I) renal cysts are considered acceptable in living kidney donor selection in terms of cancer risk. However, they tend to increase in number and size over time and might compromise renal function in donors. To clarify their implications for long-term renal function, we characterized the prevalence of renal cysts in 454 individuals who donated at our center from 2000 to 2007.

Functional independence, access to kidney transplantation and waitlist mortality.

Background: Approximately half of the patients who progress to end-stage kidney disease (ESKD) and undergo dialysis develop difficulties carrying out essential self-care activities, leading to institutionalization and mortality. It is unclear what percentage of kidney transplant (KT) candidates, a group of ESKD patients selected to be healthy enough to withstand transplantation, are functionally independent and whether independence is associated with better access to KT and reduced waitlist mortality.

Methods: We studied a prospective cohort of 3168 ESKD participants (January 2009 to June 2018) who self-reported functional independence in more basic self-care Activities of Daily Living (ADL) (needing help with eating, dressing, walking, grooming, toileting and bathing) and more complex instrumental ADL (IADL) (needing help using a phone, shopping, cooking, housework, washing, using transportation, managing medications and managing money).

Donor-Recipient Relationship and Risk of ESKD in Live Kidney Donors of Varied Racial Groups.

Rationale & Objective: Risk factors for kidney failure are the basis of live kidney donor candidate evaluation. We quantified risk for end-stage kidney disease (ESKD) by the biological relationship of the donor to the recipient, a risk factor that is not addressed by current clinical practice guidelines.

Study Design: Retrospective cohort study.

Risk of ESKD in Older Live Kidney Donors with Hypertension.

Background And Objectives: Hypertension in older kidney donor candidates is viewed as safe. However, hypertension guidelines have evolved and long-term outcomes have not been explored. We sought to quantify the 15-year risk of ESKD and mortality in older donors (≥50 years old) with versus those without hypertension.

Living kidney donation in individuals with hepatitis C and HIV infection: rationale and emerging evidence.

Purpose Of Review: HIV-infected (HIV+) and hepatitis C virus-infected (HCV+) individuals with end-stage renal disease (ESRD) have decreased access to kidney transplantation. With new opportunities provided by the HIV Organ Policy Equity (HOPE) Act and direct-acting antivirals (DAAs) for HCV, we explore the potential risks and benefits of living donor kidney transplantation from HIV+ or HCV+ donors, from the perspective of both donor health and recipient outcomes.

Recent Findings: The HOPE Act permits organ donation from both deceased and living HIV+ persons to HIV+ recipients; however, there is only clinical experience with HIV+ deceased donors to date.

The true risk of living kidney donation.

Purpose Of Review: The safety of living donor nephrectomy is essential to the continued success, growth, and sustainability of the clinical practice of living donor kidney transplantation. This review summarizes recent advances in our understanding of the perioperative and long-term risks faced by living kidney donors.

Recent Findings: Although adverse perioperative complications are extremely rare, donors particularly men, Black, or obese, frequently experience minor complications that result in delayed return to normal duties at home and work.

The changing landscape of live kidney donation in the United States from 2005 to 2017.

The number of live kidney donors has declined since 2005. This decline parallels the evolving knowledge of risk for biologically related, black, and younger donors. To responsibly promote donation, we sought to identify declining low-risk donor subgroups that might serve as targets for future interventions.

The landscape of international living kidney donation in the United States.

In the United States, kidney donation from international (noncitizen/nonresident) living kidney donors (LKDs) is permitted; however, given the heterogeneity of healthcare systems, concerns remain regarding the international LKD practice and recipient outcomes. We studied a US cohort of 102 315 LKD transplants from 2000-2016, including 2088 international LKDs, as reported to the Organ Procurement and Transplantation Network. International LKDs were more tightly clustered among a small number of centers than domestic LKDs (Gini coefficient 0.

Assessing the Attitudes and Perceptions Regarding the Use of Mobile Health Technologies for Living Kidney Donor Follow-Up: Survey Study.

Background: In 2013, the Organ Procurement and Transplantation Network began requiring transplant centers in the United States to collect and report postdonation living kidney donor follow-up data at 6 months, 1 year, and 2 years. Despite this requirement, <50% of transplant centers have been able to collect and report the required data. Previous work identified a number of barriers to living kidney donor follow-up, including logistical and administrative barriers for transplant centers and cost and functional barriers for donors.

Early Hypertension and Diabetes After Living Kidney Donation: A National Cohort Study.

Background: Living kidney donors have an increased risk of end-stage renal disease, with hypertension and diabetes as the predominant causes. In this study, we sought to better understand the timeline when these diseases occur, focusing on the early postdonation period.

Methods: We studied 41 260 living kidney donors in the United States between 2008 and 2014 from the Scientific Registry of Transplant Recipients and modeled incidence rates and risk factors for hypertension and diabetes.
