Kidney Exchange in Latin America and the Caribbean

 Kidney exchange isn't yet thriving in Latin America, but the basic infrastructure is in place. It would make a lot of sense to jumpstart kidney exchange by allowing cross border exchange, so that there would be a large enough pool of patient-donor pairs to make finding a match easy. Here's an article surveying the member countries of the Latin America and Caribbean Transplant Society.

Bastos, Juliana, David José de Barros Machado, Raquel Megale Moreira, Gustavo Fernandes Ferreira, and Elias David-Neto. "Kidney Paired Donation in Latin America and the Caribbean: An Update." Transplantation 108, no. 6 (2024): 1257-1258.

"we assess the situation of KPD in the countries affiliated with the Latin America and Caribbean Transplant Society (STALYC).

  

"Guatemala was the first country to publish a scientific report on KPD in 2018,8 with 4 kidney paired transplants performed between 2010 and 2017.

"Two reports from Argentina on local news websites reported 2-way exchanges involving 2 pairs in 20159 and 2018.10

"Costa Rica published a 2-way exchange on the hospital’s social media page in 2016,11 whereas a 2-way exchange transplantation was performed in Brazil in 2020.12

"Mexico is leading the reported KPD activity with a first experience involving 4 pairs in a chain beginning with an altruistic donor13 reported in 2019. A more recent publication reported on 22 pairs transplanted with longer chains and excellent results.14

"It is interesting to note that there are 6 countries—Panama, Ecuador, Venezuela, Peru, Chile, and Paraguay—with laws explicitly permitting KPD. Thus far, there has not been a report on KPD in those countries, which is likely due to the relatively recent publication of these legislations, all of which occurred after 2010.

"A recent publication has shed light on the potential of KPD in low-to-middle income countries (LMICs), strongly advocating for the promotion and encouragement of KPD programs, including considerations of cost advantages.17 Of additional relevance, valuable recommendations on initiating KPD programs in LMICs include starting with smaller chains, considering simultaneous surgeries, and implementing effective organ transport strategies.17 By adopting these strategies, LMICs can address compatibility issues and enhance their organ transplantation capabilities.

"Considering that KT is the superior and more cost-effective treatment option for patients with CKD, it is puzzling that the initiation of KPD programs remains limited in a region primarily composed of LMICs. Although some countries may have implemented KPD programs without publication, genuinely active programs beyond Mexico remain missing. It is crucial to emphasize that in most of these countries, deceased donor transplantation also falls significantly short of estimated needs.3,7 The entire infrastructure surrounding transplantation, including both living and deceased donors, continues to require substantial improvements. Particularly for KPD, initiatives such as educational campaigns for physicians, recipients, and donors, as well as investments in logistics and software in addition to a legal framework, need to be encouraged. Similar to KPD programs in Europe,5,18 collaborative efforts across countries could benefit smaller countries. Transplant societies, including STALYC, could play a vital role in supporting the advancement of paired donation, ensuring improved access to transplantation for their populations, especially with living donors."
