Maximizing organs for donation: the potential for ex situ normothermic machine perfusion

Area of Science:

• Organ transplantation and regenerative medicine.
• Machine perfusion technologies in transplantology.
• Pharmacological interventions for organ preservation.

Background:

• Global organ transplant waiting lists are long due to a shortage of suitable donor organs.
• Expanded donor criteria, including donation after circulatory death, increase the risk of primary graft dysfunction.
• Prolonged ischemia times associated with extended criteria donors can impair organ viability.

Approach:

• Normothermic machine perfusion (NMP) allows ex vivo assessment and potential reconditioning of donor organs.
• NMP provides a platform for targeted delivery of therapeutics directly to the organ.
• This approach minimizes systemic side effects often seen with in vivo drug administration.

Key Points:

• NMP enables objective evaluation of donor organ function before transplantation.
• Therapeutic agents can be tested and administered directly to the organ during NMP.
• Potential to improve graft function and long-term transplant outcomes.

Conclusions:

• NMP is a promising technology for addressing organ shortages and improving transplant success rates.
• Investigating novel therapeutics within NMP platforms may enhance organ viability and reduce post-transplant complications.
• This strategy supports the use of extended criteria donors and reduces primary graft dysfunction.
