A Paradigm Shift in Kidney Transplants: Exploring Normothermic Preservation

In a significant breakthrough, 34 Lives, PBC, based in West Lafayette, Indiana, has emerged as a pioneer in organ preservation and transplantation. The organization has announced the results of a groundbreaking study published in the American Journal of Transplantation, which aligns with their mission established in 2022 to reduce the number of otherwise usable kidneys that ultimately go to waste.

The Urgent Need for Change

As of April 2024, 34 Lives has successfully rescued 600 donated kidneys that were at risk of being discarded. The alarming reality is that nearly 30% of kidneys recovered for transplant in the United States go unused, resulting in over 9,000 healthy kidneys left unutilized in 2024 alone. This situation is driven by the increasing number of non-ideal donors, which include elderly individuals and those who have died due to circulatory death (DCD). Furthermore, logistical challenges and geographic barriers often hinder the timely allocation of these organs, exacerbating the issue.

Study Overview: Normothermic Machine Perfusion (NMP)

The multicenter observational study focused on the potential of Normothermic Machine Perfusion (NMP) to rescue kidneys previously deemed unacceptable for transplantation based on conventional clinical criteria. The aim was to safely assess and perfuse these marginal kidneys at a specialized center before transporting them for transplantation.

During the study, 104 donor kidneys were evaluated using NMP. Out of these, 94 kidneys were successfully accepted and transplanted, leading to an impressive rescue rate of 90%. This statistic underscores the effectiveness of NMP in extending the viable period for kidneys that would typically fail to find recipients.

Key Findings

1. High Rescue Rate: With a 90% acceptance and transplantation rate, this study showcases NMP’s capability to salvage kidneys that would otherwise be left behind.
2. Delayed Graft Function (DGF): Notably, despite longer cold ischemic times (median of 37.6 hours for the NMP group versus 22.1 hours for the control group), the DGF rate was lower at 26.3% compared to 60.2% in the control group, indicating a promising development for the quality of transplanted organs.
3. Comparable Outcomes: Both short-term graft survival and function (measured by estimated Glomerular Filtration Rate, or eGFR) showed similar results between kidneys preserved through NMP and those that were not, validating the NMP technique's efficacy.

Chris Jaynes, CEO of 34 Lives and the principal investigator of the study, emphasized the importance of NMP in ensuring that no donated kidneys are wasted. He stated, "A significant finding in this study is the feasibility of using a dedicated NMP center to extend the current limits on cold ischemia times for high-risk donor kidneys, enabling surgeons to find better-matched recipients."

Conclusion and Future Directions

The study's findings advocate for the broader application of NMP in the US organ transplant landscape. Utilizing a centralized assessment and preservation center not only improves the chances for kidneys previously considered non-viable but also reassures donors and recipients that viable kidneys won't be discarded. Moving forward, further research will be essential to better understand the long-term functions of the kidneys transplanted post-NMP.

In summary, 34 Lives is redefining the narrative surrounding kidney donation and transplantation through innovative methods. Their ongoing commitment to saving lives and improving transplant outcomes has opened new avenues for patients in urgent need of kidney transplants.
