Summary: Kidney extraction time has a detrimental effect on post-transplantation outcome. This study aimed to improve the flush-out and decrease ischemic injury by adding hydrogen sulphide (H2S) to the flush medium. The addition of H2S during flush out and static cold storage resulted in a reduction in pro-inflammatory cytokines without affecting renal function or injury markers.

Summary: Kidney transplantation is the preferred treatment for end-stage renal disease, with static cold storage being the standard preservation method. However, dynamic techniques like machine perfusion have shown potential to improve graft function and quality assessment, particularly in kidneys from extended criteria donors.

Summary: Renal transplantation is the preferred treatment for end-stage renal disease. The current gold standard for kidney preservation during transplantation is static cold storage at 4 degrees C. However, this method contributes to renal ischemia-reperfusion injury (IRI) which negatively affects graft survival and function. Recent studies focus on preserving kidneys at higher or subnormothermic temperatures to reduce the risk of cold renal IRI and enhance graft function and recipient survival.

Summary: By systematically screening gene expression profiles from over 1,000 specimens, 20 upregulated genes associated with RIRI in renal transplantation were successfully identified and validated, with 10 of them showing correlations with poor long-term transplant outcomes. Two newly identified genes, Btg2 and Rhob, were found to have crucial roles in RIRI and strong connections with NF-kappa B signaling.

Summary: Our study identified 11 different cell types in transplanted livers, with a highly complex ecosystem primarily shaped by myeloid-derived cell subsets that transition between different states and interact mutually. In transplanted steatotic livers, a pro-inflammatory phenotype of Kupffer cells (KCs) with high expression of colony-stimulating factor 3 (CSF3) was found to potentially contribute to fatty graft injury. Additionally, a subset of dendritic cells (DCs) with highly expressing XCR1 was correlated with CD8(+) T cells, mediating severer steatotic liver damage by I/R injury.

Summary: This study retrospectively analyzed data from 380 pancreas transplants and compared the impact of different preservation solutions on transplant outcomes. The results showed that the IGL-1 solution had better performance in perioperative complications and higher survival rates at 1, 3, and 5 years compared to other solutions. Therefore, using the IGL-1 solution for perfusion and organ preservation may be a promising choice in clinical pancreas transplantation.

Summary: Prolonged hypothermic oxygenated machine perfusion (HOPE) preservation of donor livers is safe and can lead to good outcomes in liver transplantation, with low incidence of complications and high survival rates. It can also reduce ischemia-reperfusion injury-related complications.

Summary: This review discusses the use of machine perfusion and mesenchymal stem cells to improve the quality and outcomes of marginal organs in transplantation. By continuously perfusing the organs to mimic physiological conditions, evaluating pre-transplant organ function, and treating the organs with pharmacological, gene, and stem cell therapy, the quality and adaptability of the organs can be enhanced. Promising preclinical results indicate the potential clinical translation of this innovative strategy to improve the quality of marginal grafts.

Summary: This study aimed to evaluate the safety and feasibility of peri-procedural alkaline phosphatase (AP) administration in living donor kidney transplantation. The results showed that the bRESCAP treatment group had lower expression of injury biomarkers in urine after 7 days, but there was no significant difference in kidney function after 1 year. Therefore, the bRESCAP treatment is feasible in kidney transplantation, might have a dampening effect on ischemia-reperfusion injury-induced renal inflammation, and raises no safety concerns.

Summary: Kidney transplantation is the preferred treatment for end-stage kidney disease, and optimizing organ condition is crucial due to the shortage of transplantable organs. This study demonstrated that supplementing the preservation solution with the S1R agonist fluvoxamine reduced cold and warm ischemic injury, improved kidney function, mitigated histological injury, and reduced inflammation. The results suggest that S1R agonists have great potential in improving organ preservation and alleviating the problem of organ shortages.

Summary: Heart transplantation is the best surgical treatment for end-stage heart failure patients, but the increasing age and high-risk factors of HTx candidates pose challenges. Donor organ preservation techniques, such as controlled hypothermia and machine perfusion, have shown potential in improving outcomes. However, the superiority of these techniques over traditional static cold storage is still debatable. This review aims to critically assess the available clinical data on donor heart preservation strategies for HTx.
