Just Released - Transplantation Direct - January Issue

Transplantation Direct for January is now online and features a wide range of topics. We have a number of articles in kidney transplantation, including prehabilitation strategies in recipient candidates, factors in deceased donors contributing to acute kidney injury, postural venous outflow problems in pregnant recipients, outcomes using high KDPI kidneys in older recipients, data on whether patiromer interacts with tacrolimus, and a first-in-human safety study on using alpha-1-microglobulin to improve kidney function. In liver transplantation, we have reports on the impact of machine perfusion (MP) on organ usage and DCD graft survival in the USA, and on the dynamics of ischemia-reperfusion injury markers in normothermic MP; there is also a comparison of transplant outcomes using 6 predictive scoring models, a study on using cardiovascular fitness tests in recipients, and a report on factors related to invasive surgical site infections. Experience using non-vascularized rectus fascia transplantation in intestinal and multi-visceral recipients is described. On the topic of organ donation, an analysis was performed on whether EBV and CMV infections can be mitigated by kidney-paired donation practices, and a study plan is described from Canada related to legislation that determines the impact of deemed consent methodologies. In the increasingly emerging practice of uterus transplantation, kinetic parameters are assessed related to immunological rejection. Indeed, this entire issue of Transplantation Direct is available by open access; please visit our website for complete details.

Tacrolimus-loaded Drug Delivery Systems in Vascularized Composite Allotransplantation: Lessons and Opportunities for Local Immunosuppression
Long-term systemic immunosuppression is needed for vascularized composite allotransplantation (VCA). The high rate of acute rejection episodes in the first posttransplant year, the development of chronic rejection, and the adverse effects that come along with this treatment, currently prevent a wider clinical application of VCA. Opportunistic infections and metabolic disturbances are among the most observed side effects in VCA recipients.
Risk Factors for Adverse Outcomes in Kidney Transplants From Donors After Circulatory Death With Normothermic Regional Perfusion: A Systematic Analysis
This study examined 1071 adult primary kidney transplants from the French-controlled donation after the circulatory determination of death (cDCD) program, which uses normothermic regional perfusion (NRP), and involves short cold ischemia times (CIT) and constrained asystole times differing by donor age.

Liver Retransplantation Using Living Donor Grafts: A Feasible Approach for Chronic Allograft Failure
The indication of living donor liver retransplantation (re-LDLT) for retransplant candidates with chronic allograft failure (CAF) is increasing because of the high mortality rate of patients on the waiting list. However, evidence supporting re-LDLT for CAF remains scarce because of technical difficulties. We aimed to examine the feasibility based on our significant case experience.

A Single-center Experience With >200 Lung Transplant Recipients With COVID-19 Infection
Although COVID-19 is no longer a declared global health emergency, data remain limited on the impact of COVID-19 in lung transplant recipients. We identified lung transplant recipients who were diagnosed with COVID-19 from March 2020 through August 2022 in our institutional database and investigated clinical outcomes. We then analyzed outcomes based on date of COVID-19 diagnosis (first wave March 2020–October 2020; second wave November 2020–2021; third wave December 2021–September 2022) and compared these results.
A Multicenter Home-based Prehabilitation Intervention in Kidney Transplant Candidates

Frailty is a modifiable risk factor for morbidity and mortality among kidney transplant (KT) candidates. We previously demonstrated that an 8-wk center-based exercise intervention is associated with improved frailty parameters in patients with advanced chronic kidney disease. This study aimed to adapt the intervention for home-based delivery and examine its feasibility, safety, and acceptability in a multicenter cohort of KT candidates.

Mitigating High-risk EBV and CMV Through Kidney Paired Donation: A Survey of Potential Donor and Recipient Candidates
High-risk cytomegalovirus (CMV) and Epstein-Barr virus (EBV) mismatches (ie, seropositive donors to seronegative recipients) among kidney transplant recipients lead to increased healthcare utilization, inferior allograft outcomes, and high mortality. We assessed the interest among prospective kidney donor and recipient candidates to participate in kidney paired donation (KPD) for averting CMV/EBV high-risk mismatches.
Impact of Hypothermic Perfusion on Immune Responses and Sterile Inflammation in a Preclinical Model of Pancreatic Transplantation
In organ transplantation, cold ischemia is associated with sterile inflammation that subsequently conditions adaptive immunity directed against the grafts during revascularization. This inflammation is responsible for venous thrombosis, which is the main postoperative complication affecting graft function. Our aim was to investigate the modulation of immune responses and endothelial function of pancreatic grafts during cold ischemia using different preservation modalities.

FDA (USA) Releases Six Guidance Documents Affecting Human Tissue for Transplantation


View a brief summary of the release by the American Association of Tissue Banks
On January 6, 2025, the FDA released six guidance documents which cover multiple aspects of donor eligibility and strategies for reducing the risk of communicable diseases, including the following:
  • Recommendations for Determining Eligibility of Donors of Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/Ps); Draft Guidance for Industry
  • Recommendations to Reduce the Risk of Transmission of Human Immunodeficiency Virus (HIV) by Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/Ps); Draft Guidance for Industry
  • Recommendations to Reduce the Risk of Transmission of Hepatitis C Virus (HCV) by Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/Ps); Draft Guidance for Industry
  • Recommendations to Reduce the Risk of Transmission of Hepatitis B Virus (HBV) by Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/Ps); Draft Guidance for Industry
  • Recommendations to Reduce the Risk of Transmission of Mycobacterium tuberculosis (Mtb) by Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/Ps); Guidance for Industry
  • Recommendations to Reduce the Risk of Transmission of Disease Agents Associated with Sepsis by Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/Ps); Guidance for Industry
