Background: This study examines outcomes of deceased donor kidney transplantation (DDKT) in recipients of kidney allografts with marginal perfusion parameters.
Methods: Allografts with marginal perfusion parameters (resistance index [RI] >0.4 and pump flow rate [F] <70 mL/min; MP group) were compared with those with good parameters (RI <0.4 and F >70 mL/min; GP group) for DDKT recipients between January 1996 and November 2017 after hypothermic pulsatile perfusion. Demographics, creatinine, cold ischemia times (CIT), delayed graft function (DGF), and recipient glomerular filtration rate at pre- and post-transplant were noted. The primary outcome was graft survival post-transplant.
Results: In the MP (n = 31) versus GP (n = 1281) group, the median recipient was aged 57 years versus 51 years; the median donor was aged 47 versus 37 years; terminal creatinine was 0.9 versus 0.9 mg/dL; CIT was 10.2 versus 13 hours, and the RI and flow were 0.46 and 60 mL/min versus 0.21 and 120 mL/min. The DGF rate was 19% (MP) versus 8% (GP). The graft survival in the MP versus GP group was 81% versus 90% (1 year), 65% versus 79% (3 years), 65% versus 73% (4 years), and 45% versus 68% (5 years).
Conclusion: Carefully selected kidney allografts after comprehensive donor and recipient evaluation may allow for the use of these routinely discarded kidneys with marginal perfusion parameters.

Machine perfusion is an emerging and transformative technology for dynamic organ preservation, assessment and repair. Whereas allografts continuously degrade during static cold storage, short-term perfusion can preserve high-quality organs for hours, enabling assessment, regional transport and improved logistics. Long-term perfusion for multiple days might extend the potential of clinical machine perfusion in the future, allowing for the assessment, reconditioning and repair of marginal or injured grafts for which more time is needed.

Although maintenance immunosuppression with calcineurin inhibitors (CNIs) has greatly reduced rejection rates in renal transplant recipients, long-term use can contribute to eventual nephrotoxicity, potentially leading to allograft injury and loss. Several clinical trials have shown that, compared with CNIs, belatacept-based maintenance immunosuppression can improve renal function, reduce the incidence of de novo donor-specific antibodies, and improve long-term patient/graft survival. However, the US Food and Drug Administration-approved belatacept-based regimen is also associated with higher acute rejection (AR) rates than CNI-based immunosuppression.

Background: The use of extended criteria donor livers (ECD) is becoming more routine in many transplant centers. These organs have higher risks for complications; however, hypothermic-oxygenated perfusion (HOPE) was found to improve outcomes, including graft survival. We aim to assess the effect of HOPE on different types of ECD liver grafts.

Introduction: Hepatitis C virus (HCV) infection is a leading cause of immune-complex mediated glomerulonephritis, specifically cryoglobulinemic and membranoproliferative glomerulonephritis, and has also been associated with non-glomerular kidney diseases. However, the prevalence of kidney disease among individuals with chronic HCV infection is unknown. Concerns about the quality of kidneys from deceased donors with HCV infection may lead centers to avoid transplanting these organs.

Extensive and complex abdominal wall defects, particularly those associated with intestinal or visceral organ damage, pose significant medical and surgical challenges. An ideal reconstruction must restore anatomy, function, sensation, and body image. Currently, no conventional reconstruction method fulfills all these criteria in such complex scenarios.
