Racial Equity in Family Approach for Patients Medically Suitable for Deceased Organ Donation.

Objectives: To conduct a contemporary analysis of the association between family approach of medically suitable potential organ donors and race/ethnicity.

Design: Retrospective review of data collected prospectively by Organ Procurement Organizations (OPOs).

Setting: Ten OPOs representing eight regions of the Organ Procurement and Transplantation Network and 26% of all deceased donor organs recovered in the United States.

Direct Measurement of DCD Donor Potential.

Background: Existing methods of comparing organ procurement organization (OPO) performance use administrative data to indirectly measure donation after circulatory death (DCD). The purpose of this study was to categorize and quantify reasons that potential DCD donors do not progress to donation to facilitate the direct measurement of OPO donor potential.

Methods: Records of all 18 685 potential organ donors referred to the organ procurement agency OneLegacy in 2021 and 2022 were reviewed, and reasons that cases did not proceed to donation were categorized and quantified.

A Machine Learning-Driven Virtual Biopsy System For Kidney Transplant Patients.

In kidney transplantation, day-zero biopsies are used to assess organ quality and discriminate between donor-inherited lesions and those acquired post-transplantation. However, many centers do not perform such biopsies since they are invasive, costly and may delay the transplant procedure. We aim to generate a non-invasive virtual biopsy system using routinely collected donor parameters.

Apheresis of Deceased Donors as a New Source of Mobilized Peripheral Blood Hematopoietic Stem Cells for Transplant Tolerance.

Background: Solid organ transplantation is the therapy of choice for many patients with end-stage organ failure; however, recipients must remain on lifelong immunosuppression, leaving them susceptible to infections and cancer. The study of transplant tolerance to prolong graft survival in the absence of immunosuppression has been restricted to recipients of living donor allografts; however, deceased donors significantly outnumber living donors. Mobilization of hematopoietic stem cells (HSCs) from the bone marrow to peripheral blood (PB) could allow PB-HSCs to be used to induce tolerance in deceased donor kidney recipients; however, a major concern is the well-known concomitant mobilization of immune cells into the liver.

Differences in Organ Donation and Transplantation in States Within the United States and in European Countries: Is There a Benefit to Opting Out?

Background: Organ donation in the United States currently requires explicit consent by an "opt-in" approach. Some European countries have reported an increase in donation rates with an "opt-out" strategy. We hypothesized that regional differences in decision making affect organ donation rates in different countries and suggest no single approach will reliably increase organ donation rates.

Cross-cultural adaptation and psychometric validation of the Flodén ATODAI instrument in the North American context.

Background: Intensive and critical-care nurses are the key to successful donor management in the critical-care setting. No studies measuring attitudes toward organ donor advocacy existed before 2011, when the 51-item Swedish "Attitudes Toward Organ Donor Advocacy Scale" was developed. The aim of this study was to translate, adapt and establish the psychometric properties of the North American version of the Flodén ATODAI (Attitudes Toward Organ Donor Advocacy Instrument) in terms of validity and reliability.

Donating Another Person's Kidney: Avoiding the Discard of Organs by Retransplantation.

Background: Procurement and retransplantation of a previously transplanted kidney reclaim a functioning organ that would otherwise have been discarded.

Methods: Case series of 3 retransplantation cases within the course of 1 calendar year.

Results: These cases illustrate how to overcome the immunological, logistical, and technical barriers that have thus far limited the potential of this approach.

Deceased organ donor screening for human immunodeficiency virus, hepatitis B virus and hepatitis C virus: Discordant serology and nucleic acid testing results.

Background: Before the 2014 policy change pertaining to infectious disease screening, many organ procurement organizations (OPOs) were supplementing serologic screening of deceased organ donors with nucleic acid testing (NAT) for human immunodeficiency virus (HIV-1), hepatitis B virus (HBV), and hepatitis C virus (HCV). The number of seronegative, NAT-positive donors has not been directly measured.

Methods: HIV, HBV, and HCV screening results of 11 229 donor referrals evaluated from 2010 to 2013 were obtained from 3 OPO-affiliated laboratories, capturing 35% of all donors in the United States.

Solid organ transplantation from hepatitis B virus-positive donors: consensus guidelines for recipient management.

Use of organs from donors testing positive for hepatitis B virus (HBV) may safely expand the donor pool. The American Society of Transplantation convened a multidisciplinary expert panel that reviewed the existing literature and developed consensus recommendations for recipient management following the use of organs from HBV positive donors. Transmission risk is highest with liver donors and significantly lower with non-liver (kidney and thoracic) donors.

Outcomes of shipped live donor kidney transplants compared with traditional living donor kidney transplants.

The disparity between kidney transplant candidates and donors necessitates innovations to increase organ availability. Transporting kidneys allows for living donors and recipients to undergo surgery with a familiar transplant team, city, friends, and family. The effect of shipping kidneys and prolonged cold ischemia time (CIT) with living donor transplantation outcomes is not clearly known.

Donor-derived West Nile virus infection in solid organ transplant recipients: report of four additional cases and review of clinical, diagnostic, and therapeutic features.

We describe four solid-organ transplant recipients with donor-derived West Nile virus (WNV) infection (encephalitis 3, asymptomatic 1) from a common donor residing in a region of increased WNV activity. All four transplant recipients had molecular evidence of WNV infection in their serum and/or cerebrospinal fluid (CSF) by reverse transcription polymerase chain reaction (RT-PCR) testing. Serum from the organ donor was positive for WNV IgM but negative for WNV RNA, whereas his lymph node and spleen tissues tested positive for WNV by RT-PCR.

Investigating geographic variation in mortality in the context of organ donation.

Organ procurement organizations (OPOs) report a nearly fourfold difference in donor availability as measured by eligible deaths per million population (PMP) based on hospital referrals. We analyzed whether mortality data help explain geographic variation in organ supply as measured by the number of eligible deaths for organ donation. Using the 2007 National Center for Health Statistics' mortality data, we analyzed deaths occurring in acute care hospitals, aged ≤ 70 years from cerebrovascular accidents and trauma.

Transmission of Trypanosoma cruzi by heart transplantation.

Background: Trypanosoma cruzi infection (i.e., Chagas disease) is an unusual complication that can occur after solid-organ transplantation and that can result in severe illness or death.

Factors associated with discard of recovered kidneys.

We reviewed diseased donor (DD) kidney usage at a single Organ Procurement Organization in Southern California to more closely examine factors associated with discard. From 2001 to 2006, 3863 kidneys from 1959 DDs were recovered, but 454 (11.8%) were subsequently discarded.

Can machine perfusion decrease the likelihood of discard among biopsied kidneys?

Many factors, such as donor risk factors and renal function, have been shown to be associated with an increased likelihood of discard after recovering kidneys from deceased donors. When these factors are insufficient for assessment, renal biopsy is often performed at the time of harvest to assess suitability. Our aims were to identify factors that predict the discard of a biopsied kidney and to assess the impact of machine perfusion (MP) on kidney discard.

Organ donation and utilization in the United States, 1997-2006.

Deceased organ donation has increased rapidly since 2002, coinciding with implementation of the Organ Donation Breakthrough Collaborative. The increase in donors has resulted in a corresponding increase in the numbers of kidney, liver, lung and intestinal transplants. While transplants for most organs have increased, discard and nonrecovery rates have not improved or have increased, resulting in a decrease in organs recovered per donor (ORPD) and organs transplanted per donor (OTPD).
