Impact of single centre kidney‐exchange transplantation to increase living donor pool in India: A cohort study involving non‐anonymous allocation.

Aim: In India, 85% of organ donations are from living donors and 15% are from deceased donors. One‐third of living donors were rejected because of ABO or HLA incompatibility. Kidney exchange transplantation (KET) is a cost‐effective and legal strategy to increase living donor kidney transplantation (LDKT) by 25%–35%. Methods: We report our experience with 539 KET cases and the evolution of a single‐centre program to increase the use of LDKT. Results: Between January 2000 and 13 March, 2024, 1382 deceased donor kidney transplantations and 5346 LDKT were performed at our centre, including 10% (n = 539) from KET. Of the 539 KET, 80.9% (n = 436) were ABO incompatible pairs, 11.1% (n = 60) were compatible pairs, and 8% (n = 43) were sensitized pairs. There were 75% 2‐way (n = 2 × 202 = 404), 16.2% 3‐way (n = 3 × 29 = 87), 3% 4‐way (n = 4 × 4 = 16), 1.8% 5‐way (n = 5 × 2 = 10), 2.2% 6‐way (n = 6 × 2 = 12), and 1.8% 10‐way KET (n = 10 × 1 = 10). Of the recipients 81.2% (n = 438) were male and 18.8% (n = 101) were female, while of the donors, 78.5% (n = 423) were female and 21.5% (n = 116) were male. All donors were near relatives; wives (54%, n = 291) and mothers (20%, n = 108) were the most common donors. At a median follow‐up of 8.2 years, patient survival, death censored graft survival, acute rejection, and median serum creatinine levels of functioning grafts were 81.63% (n = 440), 91% (n = 494), 9.8% (n = 53) and 1.3 mg/dL respectively. We credited the success to maintaining a registry of incompatible pairs, high‐volume LDKT programs, non‐anonymous allocation and teamwork. Conclusion: This is the largest single‐centre KET program in Asia. We report the challenges and solutions to replicate our success in other KET programs. [ABSTRACT FROM AUTHOR]
