Kidney paired donation is the most cost-effective approach in incompatible donor-recipient pairs. Incompatibility may be due to blood group, human leucocyte antigen crossmatch or both. In many cases of a living donor kidney transplant, there is only one potential donor who becomes unsuitable due to any of the above mentioned factors. In kidney paired donation, donor-recipient pairs are exchanged to sort out the incompatibility. We report our first successful three-way kidney exchange transplantation from North India. As deceased donor program is still in evolving stage in most parts of our country and transplant with desensitization protocol is associated with financial constraints, infections, and lack of availability in many centers, kidney paired donation is a valuable approach to expand the donor pool.

| Introduction|| |
Kidney paired donation (KPD) or paired exchange is an exchange of the kidneys from living donors deemed by virtue of blood group or histocompatibility criteria to be incompatible to their intended or designated recipients. KPD is the most cost-effective approach in incompatible donor-recipient pairs (DRPs).,,, Many potential living kidney donors are not able to donate due to blood type or antibody incompatibility. Historically, these donors would be turned away and the patients would lose the opportunity to receive a life-saving transplant. KPD overcomes these incompatibilities by swapping kidneys. KPD has expanded to include compatible pairs, nondirected donors, three-way and multiple exchanges, and living/deceased donor exchanges.,,,
Here, we report our first successful three-way KPD resulting in the transplantation of a highly sensitized and two ABO-incompatible DRPs.
| Case Report|| |
We have an experience of frequently doing two-way paired exchange transplants. After legal permission, all three DRPs were informed about the pros and cons of KPD prior to initiating evaluation. Each pair was counseled separately and then together. They were given sufficient time to discuss among their family members and the transplant team. They were screened for pretransplant immunological risk, occult infections, and other risk factors to reduce unequal transplant outcomes.
Recipient-1 came for preemptive renal transplant with the wife as a potential donor. His native disease was chronic tubulointerstitial nephritis with hypertension as comorbidity. The blood group of recipient was O and donor was A. Anti-A titer was 1:1024. The donor had difficult renal anatomy with two renal arteries on the right side, three renal arteries on the left side, and two renal veins on each side. They opted for KPD due to financial constraints.
Recipient-2 had a blood group matched donor but he had both complement-dependent cytotoxicity (CDC) and flow cytometry crossmatch (FCXM) positive with the donor. Single-antigen bead assays for class-1 revealed anti-human leukocyte antibodies (HLA) with 3 loci showing more than 2000 MFI and 2 loci showing more than 1000 MFI. He was denied for transplant due to high sensitization to donor.
Recipient-3 had blood group A and donor (wife) was B. His native kidney disease was diabetic nephropathy. The donor was obese. She had one renal artery on the right side and two on the left side, and single renal vein on each side. They also opted for KPD due to financial constraints [Table 1] and [Table 2].
Three-way exchange transplant was planned for recipient 1 with donor 2, recipient 2 with donor 3, and recipient 3 with donor 1. CDC crossmatch and FCXM were negative with their donors [Table 3]. diethylene triamine pentaacetic acid (DTPA) renal scan of all three donors before transplant had normal glomerular filtration rate (GFR) (GFR >40 ml/min on each side). All recipients and donors had positive cytomegalovirus (CMV) serology for IgG and negative for IgM.
After informed and written consent, all surgeries were performed on the same day. The team included nephrologists, urologists, and anesthesiologists. Twenty personnel worked for 14 h for all transplants from 7 am to 9 pm. One donor underwent laparoscopic donor left nephrectomy and two others underwent open right nephrectomy due to difficult renal anatomy. Induction therapy included methylprednisolone (500 mg) initiated a night before the surgery with tapering over next 3 days. r-ATG (1.5 mg/kg each dose) was started on the morning of transplant day. Three doses of ATG were given over 3 consecutive days. Tacrolimus (0.1 mg/kg divided into 2 doses) and mycophenolate sodium (360 mg tab—2 tabs twice daily) were started on the day before surgery.
All patients showed brisk urine output immediately after the transplant and normalization of serum creatinine over the next 3 days. Delayed graft function (DGF) or rejection was not seen in any patient. All had stable graft function on discharge without any medical and surgical complications. All patients were given valganciclovir and trimethoprim/sulfamethoxazole prophylaxis against CMV and Pneumocystis pneumonia, respectively. None of the donors suffered from any medical or surgical complications. Donors were discharged on postoperative day 5 (POD 5) and recipients were on POD 8. All patients are doing well over a follow-up period of 9 months [Table 4].
| Discussion|| |
ABO incompatibility and HLA sensitization represent two greatest barriers to improving the live donation rate. KPD is feasible, successful, and if applied to a larger donor pool, capable of expanding access to renal transplants.,,,,, KPD avoids the extra immunosuppression and allows for the usual excellent outcomes associated with living unrelated transplants.
The concept of KPD was first proposed by Dr Felix Rappaport in 1986. In 1991, the first KPD program started in South Korea. In 1999, first European KPD transplants were performed in Switzerland. After 2000, several KPD systems became active in the United States. Three-way KPD was first reported in the United States in 2005. In the United States, the national kidney registry organizes the majority of KPD transplants including the largest swaps. The first large swap was a 60 participants chain in 2012 that appeared on the front page of New York Times and the second, even larger, swap including 70 participants which was completed in 2014.
In the United States, advanced donation began in 2012 and expanded in 2014 to include voucher donations. These innovative approaches are now eliminating the traditional chain and loop swaps, replaced by one deep chain.
In India: The first two-way KPD transplant was performed in June 2000 in IKDRC, Ahmedabad. They performed 10 kidney paired donation transplants on World Kidney Day in 2013. At this center, three-way, four-way, and six-way KPD transplants have been done in recent years.,,, We have performed first successful three-way kidney exchange transplant from North India.
When KPD first started, the focus was only on enrolling incompatible DRPs. As paired exchange grew and the process became faster and more reliable, patients with compatible donors that wanted a better match began enrolling in KPD. Better matched kidney transplant correlates with a lower lifetime mortality rate.
Long-term hemodialysis is not widely available in our country and morbidity and mortality on dialysis are unacceptably high. A kidney transplant offers significant survival and quality-of-life advantages so living donor kidney transplant (LDRT) soon after the diagnosis of ESRD is the only viable form of long-term renal replacement therapy for most patients. KPD is the first opportunity to substantially increase donor pool by utilizing high-quality organs, rather than merely accepting more organs of uncertain caliber. A large majority of patients are not aware of KPD. However, after counseling, we can achieve strong support for it. National KPD program may act as a final authority in this regard.
Indian Society of Organ Transplantation (ISOT) has recently published the guidelines for KPD to increase LDRT in our country. They suggested that a three-way exchange has optimum quality and quantity of matching. Their recommendations were based on meeting organized at Chennai in March 2017 followed by a workshop in New Delhi in April 2017 under the aegis of ISOT.
| Conclusion|| |
As the deceased donor program is still in evolving stage in most parts of our country and transplant with desensitization protocol is associated with financial constraints, infections and lack of availability in many centers, KPD is a valuable approach to expand the donor pool in renal transplant.
