Machine Perfusion Modulates Cold Preservation Injury in Kidney Transplantation: IDEAL Stage 4 OPTN Population Cohort Study

An exciting new landmark OPTN population cohort study by Tingle et al. published in American Journal of Transplantation examines how different HMP strategies influence kidney transplant outcomes. Utilizing data from over 137,000 deceased donor kidney transplants from 2010-2023, the overwhelming majority were preserved on LifePort Kidney Transporter!

The study shows:

  • HMP significantly reduces DGF regardless of HMP type. This includes: continuous HMP, end-ischemic HMP, and transport-only HMP
  • The protective effect against DGF of HMP over SCS was greater with increasing cold preservation time, especially for end-ischemic HMP
  • Continuous, end-ischemic, and transport-only HMP modalities were all significantly associated with shorter length-of-stay and improved 5-year graft survival

This study challenges the previously debated end-ischemic HMP strategy. According to the data (and with IDEAL Stage 4 real-world evidence) end-ischemic HMP does improve outcomes, especially when cold time is prolonged.

Key takeaway: No matter how HMP is logistically used, the outcomes for kidney transplant recipients are improved – further honoring the gift of life.
