[Transplant cross-over, an attractive option]
Abstract:
Kidney transplant from living donors is an excellent option for patients with end- stage renal disease: around the world approximately 10-20% of patients on waiting lists have intended living donors incompatible by blood type or for the presence of donor-specific antibodies. Current strategies to overcome these barriers are desensitization protocols and the recent option of the kidney exchange programs. In this work we describe the types of donor exchange programs, from the two-way Kidney Paired Donation, where two incompatible donor-recipient couples exchange donors, to complex chains of transplants where the altruistic donation of a kidney (Living Non-direct Donor, or non-specific donation) is associated to a Kidney Paired Exchange Program (Domino Kidney Paired Donation, NEAD chains). The thesis also discusses some related ethical topics that have become international matters of debate, as well as some important cultural and social arguments for and against the application of kidney exchanges in Italy.
Insights
Kidney exchange programs offer solutions for patients with end-stage renal disease facing donor incompatibility. These programs facilitate transplants through paired donations and complex chains, overcoming blood type and antibody barriers.
Area of Science:
- Nephrology
- Transplantation immunology
- Medical ethics
Context:
- Living donor kidney transplantation is a preferred option for end-stage renal disease.
- 10-20% of potential living donor-recipient pairs face incompatibility due to blood type or donor-specific antibodies.
- Kidney exchange programs (KEP) and desensitization protocols are strategies to overcome these barriers.
Purpose:
- To describe various types of kidney exchange programs, including two-way Kidney Paired Donation and complex chains (NEAD chains).
- To discuss ethical, cultural, and social arguments surrounding kidney exchanges, particularly in Italy.
Summary:
- Kidney exchange programs facilitate incompatible living donor transplants.
- These programs range from simple two-way exchanges to complex chains initiated by altruistic donations.
- The discussion includes ethical and socio-cultural considerations of implementing kidney exchanges.
Impact:
- KEP expands the donor pool for patients with end-stage renal disease.
- Facilitates transplantation for previously incompatible pairs.
- Informs ethical and policy debates regarding organ transplantation.

Crossover Experiments
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
