Background: The shortage of donor kidneys has led to the use of marginal donors, e.g., those whose kidneys are donated after circulatory death. Preservation of the graft by hypothermic machine perfusion (HMP) provides a viable solution to reduce warm ischemic damage. This pilot study was undertaken to assess the feasibility and patient safety of the AirdriveTM HMP system in clinical kidney transplantation. Methods: Five deceased-donor kidneys were preserved using the oxygenated Airdrive HMP system between arrival at the recipient center (Amsterdam UMC) and implantation in the patient. The main study end-points were adverse effects due to the use of Airdrive HMP. Secondary end-points were clinical outcomes and perfusion parameters. All events occurring during the transplantation procedure or within 1 month of follow-up were monitored. Results: Five patients were included in this pilot study. No technical failures were observed during the preservation period using the Airdrive HMP. Mean perfusion parameters were: duration 8.5 h (3–15 h), pressure 25 mm Hg (18–25 mm Hg), flow 49.77 mL/min (19–58 mL/min), resistance 0.57 mm Hg/min/mL (0.34–1.3 mm Hg/min/mL), and temperature 8.2 °C (2–13°C). Mean cold ischemia time (CIT) was 20.2 h (11–29.5 h). No adverse events or technical failures were observed during preservation and transplantation or during the 1-month follow-up. Conclusions: This pilot study showed the feasibility of the use of the Airdrive HMP system with no adverse events in clinical kidney transplantation.

Abstract Background Changes in recipient and donor factors have reopened the question of survival benefits of kidney transplantation versus dialysis. Methods We analysed survival among 3808 adult Belgian patients waitlisted for a first deceased donor kidney transplant from 2000 to 2012. The primary outcome was mortality during the median waiting time plus 3 years of follow-up after transplantation or with continued dialysis. Outcomes were analysed separately for standard criteria donor (SCD) and expanded criteria donor (ECD) kidney transplants. We adjusted survival analyses for recipient age (20–44, 45–64 and ≥65 years), sex and diabetes as the primary renal disease. Results Among patients ≥65 years of age, only SCD transplantation provided a significant survival benefit compared with dialysis, with a mortality of 16.3% [95% confidence interval (CI) 13.2–19.9] with SCD transplantation, 20.5% (95% CI 16.1–24.6) with ECD transplantation and 24.6% (95% CI 19.4–29.5) with continued dialysis. Relative mortality risk was increased in the first months after transplantation compared with dialysis, with equivalent risk levels reached earlier with SCD than ECD transplantation in all age groups. Conclusions The results of this study suggest that older patients might gain a survival benefit with SCD transplantation versus dialysis, but any survival benefit with ECD transplantation versus dialysis may be small.

Background.Delayed graft function (DGF) remains an important problem after kidney transplantation and reduced long-term graft survival of the transplanted organ. The aim of the present study was to determine if the development of DGF was associated with a specific pattern of inflammatory gene expression in expanded criteria of deceased donor kidney transplantation. Also, we explored the presence of correlations between DGF risk factors and the profile that was found.Methods.Seven days after kidney transplant, a cDNA microarray was performed on biopsies of graft from patients with and without DGF. Data was confirmed by real-time PCR. Correlations were performed between inflammatory gene expression and clinical risk factors.Results.From a total of 84 genes analyzed, 58 genes were upregulated while only 1 gene was downregulated in patients with DGF compared with no DGF (P=0.01). The most relevant genes fold changes observed was IFNA1, IL-10, IL-1F7, IL-1R1, HMOX-1, and TGF-β. The results were confirmed for IFNA1, IL-1R1, HMOX-1 and TGF-β. A correlation was observed between TGF-β, donor age, and preablation creatinine, but not body mass index (BMI). Also, TGF-βshowed an association with recipient age, while IFNA1 correlated with recipient BMI. Furthermore, TGF-β, IFNA1 and HMOX-1 correlated with several posttransplant kidney function markers, such as diuresis, ultrasound Doppler, and glycemia.Conclusions.Overall, the present study shows that DGF is associated with inflammatory markers, which are correlated with donor and recipient DGF risk factors.
