Nonheart-beating donors: the Maastricht experience

Summary

Nonheart-beating (NHB) donors increase kidney availability, showing similar long-term transplant success as heart-beating (HB) donors despite initial delayed function. NHB donors are crucial for reducing transplant waiting lists.

Area of Science:

  • Nephrology
  • Transplantation Immunology
  • Organ Donation

Background:

  • Increasing organ transplant waiting lists necessitate expanding donor sources.
  • Nonheart-beating (NHB) donors offer a viable option to increase kidney availability.
  • NHB donor programs have been implemented globally, with specific protocols developed.

Purpose of the Study:

  • To evaluate the short-term and long-term outcomes of kidney grafts from NHB donors compared to heart-beating (HB) donors.
  • To identify risk factors for delayed graft function in NHB donor kidney transplants.
  • To assess the contribution of NHB donors to the overall kidney transplant supply.

Main Methods:

  • Retrospective multicenter study comparing NHB donor kidneys with HB donor kidneys transplanted until 1992.

  • In situ perfusion technique used for kidney retrieval from NHB donors.
  • Analysis of graft function, delayed function (DF), serum creatinine levels, and patient/graft survival rates up to 5 years.

    • Main Results:

    • NHB donor kidneys showed significantly more delayed function (DF) and higher serum creatinine levels at one month post-transplant compared to HB donor kidneys.
    • Long-term outcomes (up to 5 years) were comparable between NHB and HB donor groups, with similar graft and patient survival rates.
    • The number of HLA-DR mismatches was identified as a significant risk factor for delayed graft function, independent of donor type (HB or NHB).

    Conclusions:

    • NHB donors significantly contribute to reducing the gap between kidney offer and demand.
    • Transplant centers should integrate NHB donors into their procurement programs to expand the donor pool.
    • Further research is needed to improve short-term graft function and develop reliable viability assessment tools for NHB donors.
