"Better to exchange kidneys than bombs."

 Some coffee cups  should naturally come in pairs, so that you have one for a friend in need. (These recently arrived in the mail, from Laurie Lee)

Better to exchange kidneys than bombs

I was quoted as having said that to Marco della Cava, the USA Today reporter who wrote about the first kidney exchange between Israel and the UAE.

“Better to exchange kidneys than bombs,” says Roth, adding that using computers to search the world for medical solutions radically increases the chances of patients getting help. “International boundaries are artificial markers. Kidney disease doesn’t care about that.”

WHO Resolution on Kidney Disease and Transplantation

The  78th World Health Assembly in May, 2025 recognized kidney failure as a global problem, with transplantation as the preferred treatment.

Here's a news story from the International Society of Nephrology (ISN):

Historic win for kidney health as WHO adopts global resolution

Here's the resolution:

WHO Resolution: Reducing the burden of noncommunicable diseases through promotion of kidney health and strengthening prevention and control of kidney disease

"The Seventy-eighth World Health Assembly

...

"(PP5) Recognizing that approximately 674 million people live with chronic kidney disease, comprising 9% of the global population2 and concerned that kidney disease is one of the fastest-growing causes of death globally and is projected to become the fifth leading cause of death by 2050, with a projected 33% increase in age-standardized death rate and a 28% increase in age-standardized disability-adjusted life years (DALYs) if no action is taken;

"(PP6) Recalling resolution WHA77.4 on increasing the availability, ethical access, and oversight of the transplantation of human cells, tissues, and organs, which urges countries to adopt preventive strategies and incorporate transplantation into the continuum of care of non-communicable and other diseases that may lead to the need for transplantation in accordance with their national contexts, and that requests the Director-General to support Member States in implementing the elements of the Resolution, particularly through the design of a Global Strategy on Donation and Transplantation.

...

" URGES Member States, in accordance with their national context and priorities, to: 

...

"(6) take measures to promote progressive access to kidney replacement therapy, of which kidney transplantation is preferred, enabling timely referral for transplantation, as well as by implementing interventions to maximize the availability of organs for clinical use aligned with the WHO Guiding Principles on human cell, tissue and organ transplantation"

 #########

 As I've noted elsewhere, the WHO has some counterproductive policies regarding transplantation (and blood and plasma donation, etc), but this particular resolution seems like a positive one.

Notes from Prague (kidney exchange, market design, and progress on a new book)

I flew back to California yesterday, after spending some time in Czechia and Italy talking about kidney exchange.  Here is a video of the public talk I gave at Prague Castle.  Among other things it highlights the Czech kidney exchanges with Israel. (I had the pleasure of meeting  Prof. Jiri Fronek, the distinguished surgical pioneer who led the Czech side of that effort.)

https://youtu.be/jrrlNWMkQyE?feature=shared


I also had the privilege of visiting CERGE-E(Center for Economic Research and Graduate Education - Economics Institute) where my host was Prof  Štěpán Jurajda.  He and I first met when we were both at the University of Pittsburgh in the 1990s.

And here's an interview with the Economic newspaper  Hospodářské noviny  that starts off with the optimistic notion that I may have just (largely) completed the draft of a new book:)

Zkoumá trhy, kde peníze nevládnou. Ledvinu ani lásku si za ně většinou nekoupíte, říká nobelista Alvin Roth [ He explores markets where money doesn't rule. You can't usually buy a kidney or love with it, says Nobel laureate Alvin Roth]

“Before flying from the USA to Prague, economist and Nobel laureate Alvin Roth managed to send the publisher a draft of his new book, which he is currently finishing. He calls it Controversial Markets. Between an afternoon lecture for students at the CERGE-EI Institute in Prague and an evening lecture at Prague Castle, he also found time for an interview with Hospodářské noviny, in which he outlines what his new book will be about. One of the controversial markets he deals with, for example, is the organ transplant market."

Kidneys and Controversies at Mt. Sinai hospital

 I gave a talk yesterday at Mt. Sinai hospital. They had encouraged me to talk about controversies, which I happily did.  They were a sympathetic audience (although the majority of their last five speakers would not have been:)

Peter Singer interview in the NYT

 The NYT interviews the eminent philosopher:

Peter Singer Wants to Shatter Your Moral Complacency  By David Marchese

Q. "I think of you as being best known for your work on animals and ethics, which flows out of utilitarian principles — that the right action is the one that produces the most good. But you’re also seen as one of the godfathers of effective altruism. Can you explain what effective altruism is and how it builds on utilitarianism?

A. "Sure. Effective altruism is the view that firstly, we ought to try to make the world a better place. Doesn’t mean that we all have to become saints, but it should be an important goal for people to think, What can I do to make the world better? And to think about that in a global way, not just for me and my family and those close to me but for people anywhere in the world and, indeed, for beings capable of suffering who are not of our species. Effective altruism developed into a kind of a social movement to encourage people to do that, and effective altruists have done a lot of research to try to find which are the most effective charities in different areas. What is the connection with utilitarianism? I think if you are a utilitarian, you ought to be an effective altruist. Because if you’re a utilitarian you ought to want to reduce suffering and increase happiness, and given that we all have limited resources, surely we should be using those resources as effectively as possible to do as much good as we can."

Kidney exchange chains between Israel and Cyprus

 Israel Hayom has the story. (Itai Ashalgi's software gets a shout-out):

Unprecedented Israel-Cyprus kidney exchange saves 8 lives. Cross-border medical collaboration showcases the power of organ donation and transplant innovation.    By  Eleanor Favriker/Makor Rishon

"In a remarkable display of international medical cooperation, eight kidney transplants have been performed across Israel and Cyprus as part of a pioneering cross-border organ exchange program. The intricate operation, involving multiple hospitals and a meticulously coordinated logistics effort, was made possible by two altruistic donors who approached the National Transplant Center, initiating a "transplant chain."

"The joint operation, conducted on Monday, saw five procedures taking place in Israel and three in Cyprus. The National Transplant Center matched the pairs using specialized computer software, drawing from an international database containing incompatible family member pairs.

"Starting at 5:00 a.m., kidneys harvested at Hadassah and Soroka hospitals were transported by ambulance to the airport and flown to Cyprus. Concurrently, another kidney from Hadassah was transferred to Soroka, while one from Beilinson was sent to Hadassah. At 2:00 p.m., two kidneys arrived from Cyprus, destined for Beilinson and Hadassah. By 6:00 p.m., all transplants were completed in both countries, with recipients in good condition and new kidneys functioning.

"In Israel, three transplants occurred at Hadassah, one at Beilinson, and one at Soroka, with an additional Hadassah transplant performed a day earlier. In total, Israel saw 10 surgeries: five kidney removals and five transplants.

"Professor Shlomo Mor Yosef, chairman of the Steering Committee, said, "I commend the cooperation between Israel and Cyprus. These exchanges provide solutions for patients with antibodies. I urge every family with a patient needing a kidney transplant to join the exchange database if no match is found among them."

"Dr. Tamar Ashkenazi commented, "This marks our first two-way kidney exchange with Cyprus. Their single transplant center in Nicosia performed six surgeries in one day, supported by a surgeon from England. I'd like to thank Ms. Rona Simon, who manages our exchange database, facilitating over 60 successful cross-transplants annually. Israel maintains similar programs with the Czech Republic, Austria, and the United Arab Emirates."

WHO Says Countries Should Be Self-Sufficient In (Unremunerated) Organs And Blood, by Krawiec and Roth

 Requiring national self sufficiency in blood and plasma supplies is particularly hard on low and middle income countries, as is limiting the possibility of participating in active kidney exchange programs.

WHO Says Countries Should Be Self-Sufficient In (Unremunerated) Organs And Blood by Kimberly D. Krawiec and Alvin E. Roth : August 24, 2024,   Available at SSRN: https://ssrn.com/abstract=4935827

Abstract: This chapter critiques the twin World Health Organization (WHO) principles of self-sufficiency and nonremuneration in organs and blood, urging a more sensible approach to the scarce resources of blood products and transplantable organs. WHO and other experts have failed to acknowledge the tension between self-sufficiency and nonremuneration in blood products--no country that fails to pay plasma donors is self-sufficient. Furthermore, international cooperation and cross-border transplantation provide numerous benefits, especially in smaller countries and those without well-developed domestic exchange programs. The combination of these twin principles denies to health care many of the benefits that trade has brought to so many other human endeavors and the effects are particularly damaging to low and middle income countries. Substances of human origin are special, but not so special that we prohibit plasma or organ donation. We should be open to exploring and experimenting with ways to bring to health care some of the benefits that trade has brought to so many other human endeavors, such as the production and distribution of food and lifesaving vaccines and other medicines.


Here's the concluding paragraph:

"We close by noting that the combination of the nonremuneration principle and the self-sufficiency principle deny to health care many of the benefits that trade has brought to so many other human endeavors. Substances of human origin are special, but not so special that we prohibit plasma or organ donation. So we should be open to exploring and experimenting with ways to bring to health care some of the benefits that trade has brought to so many other human endeavors, such as the production and distribution of food and lifesaving vaccines and other medicines."

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."

Call for kidney exchange in Jordan

 Here's a paper by Jordanian transplant docs, pointing out that kidney exchange (and perhaps cross border kidney exchange) would be useful for Jordan, a small country with little deceased donation.

Al-Thnaibat, Mohammad H., Mohammad K. Balaw, Mohammed K. Al-Aquily, Reem A. Ghannam, Omar B. Mohd, Firas Alabidi, Suzan Alabidi, Fadi Hussein, and Badi Rawashdeh. "Addressing Kidney Transplant Shortage: The Potential of Kidney Paired Exchanges in Jordan.Journal of Transplantation 2024 (2024).

Abstract

Jordan performed the Middle East’s first living-donor kidney transplant in 1972. In 1977, the country became one of the first Arab countries to regulate organ donation and transplantation. Despite these early advances in living donor transplantation, Jordan’s organ donation after brain death program remains inactive, making it challenging to meet organ demand and placing many patients on long transplant waiting lists. As of 2020, only 14.2% of the patients with end-stage kidney disease have access to a living donor. The scarcity of compatible living donors exacerbates Jordan’s organ shortage, leaving patients with extended waits and uncertain transplant prospects. Due to the lack of living donors and the inactive brain death donation program, additional options are needed to meet organ demand. Kidney paired exchange (KPE), emerges as a potential solution to the problem of donor shortage and donor-recipient incompatibility. By allowing living donors to direct their donated organs to different compatible recipients, KPE offers the promise of expanding transplant opportunities for patients without suitable living donors. However, the current Jordanian law restricting living kidney donation to fifth-degree relatives further limits the pool of potential donors, aggravating the organ shortage situation. This article explores the feasibility of implementing KPE in Jordan and proposes an approach to implementing KPE in Jordan, considering ethical and legal aspects to substantially increase kidney transplants.

Kidney exchange between Portugal and Spain, and prospects for global kidney exchange

 Here's an article from a Portuguese hospital that has engaged in kidney exchanges with Spanish hospitals that have resulted in three transplants for Portuguese patients since the program was initiated in 2017.  The paper considers how international kidney exchange can be expanded globally, so as to have significant effects on the health of Portuguese and other patients.  

The concluding  two paragraphs of the paper speak about global kidney exchange, and the controversy that it has aroused, particularly in Spain, where there has been opposition to significant cross-border kidney exchange.

Francisco, José Teixeira, Renata Carvalho, Joana Freitas, Miguel Trigo Coimbra, Sara Vilela, Manuela Almeida, Sandra Tafulo et al. "International Crossed Renal Donation – The Experience of a Single Center," Brazilian Journal of Transplantation, v. 26 (2023)

"Introduction: Kidney transplantation is the preferred treatment for end-stage chronic kidney disease, however, the shortage of organs can result in long waiting times. Living donor kidney transplantation offers an alternative to cadaver donor, but HLA or AB0 incompatibility can represent a significant obstacle. This study aimed to show the results achieved by a Portuguese hospital since its integration into an international cross-donation program, the South Alliance for Transplants (SAT). 

"Methods: The SAT program was founded in 2017 and is made up of ten Spanish hospitals, three Italian hospitals and one Portuguese hospital. The program takes place every 4 months and only enrolls pairs who are incompatible. Organ transport is carried out in partnership with the Portuguese Air Force. 

"Results: Three different crosses were carried out in partnership with three Spanish hospitals, culminating in the transplantation of three Portuguese patients out of a total of seven patients. The first crossing was carried out in March 2020, at the beginning of the COVID-19 pandemic, with the partnership of two Portuguese hospitals and a Spanish hospital, involving 1 donor/recipient pair from each country,... The second occurred in December 2021 with 3 donor/recipient pairs (1 Portuguese in which the recipient had anti-donor antibodies and positive crossmatch with the potential donor; and 2 from two Spanish hospitals),... The third crossing also took place in December 2021 with 2 donor/recipient pairs (1 Portuguese and 1 Spanish)

...

"A Global Kidney Exchange Program (GKEP), an idea initiated by Rees et al.,16 which involves kidney paired donation between high-income and low-income and medium-income countries (LMICs). Beyond the potential benefits associated with this type of transplantation, similar to those already addressed for international programs, there are concerns about the ethical implications of  such  programs.  They  may  perpetuate  existing  inequalities  between  high  and  low-income  countries,  which  has  motivated  a  statement  from  the  Declaration  of  Istanbul  Custodian  Group.17  Some  critics  argue  that  the  practices  of  most  PRMBs  lack  transparency, leaving room for exploitation and corruption,18 or raise ethical concerns regarding the commodification of organs.19On the other hand, proponents of the idea argue that a GKEP could help address the global shortage of donor organs and provide lifesaving  opportunities  for  patients  in  need.  They  also  note  that  such  programs  could  foster  collaboration  and  information-sharing between countries and institutions, potentially leading to improvements in transplant practices worldwide.16,20 Despite the controversy surrounding the proposal, the idea of a GKEP remains an intriguing possibility for advancing kidney transplantation on a global scale.

"CONCLUSION: Our experience and that of other locations show that programs like these offer numerous benefits, such as expanding the pool of available donors, improving compatibility between donors and recipients, and avoiding the costs and risks associated with desensitization therapies for ABO or HLA incompatible transplantations. These programs represent a valuable option for individuals who require a kidney transplant and can be an effective means of increasing transplant success rates and improving quality of life for patients. However, the success of these programs depends on the number of pairs enrolled. To ensure the success of these programs, there is a need for greater awareness, education, and promotion of their benefits and outcomes among the public, healthcare providers, and policymakers alike.

Global disparities in kidney disease and care

 Here's a report on the availability of treatment of kidney disease around the world.  If you are unlucky enough to have kidney failure (which is a top 10 cause of death), it's good to be in North America or Western Europe. Most countries (70%) have at least a minimal capacity to perform transplants. But if I read the map correctly, preemptive kidney transplants (i.e. transplants before dialysis, in map D below) are relatively common only in the U.S., Britain, and Norway. (And worldwide, a transplant costs less than two years of dialysis...)

Bello, A.K., Okpechi, I.G., Levin, A., Ye, F., Damster, S., Arruebo, S., Donner, J.A., Caskey, F.J., Cho, Y., Davids, M.R. and Davison, S.N., 2024. An update on the global disparities in kidney disease burden and care across world countries and regions. The Lancet Global Health, 12(3), pp.e382-e395.

"Background

"Since 2015, the International Society of Nephrology (ISN) Global Kidney Health Atlas (ISN-GKHA) has spearheaded multinational efforts to understand the status and capacity of countries to provide optimal kidney care, particularly in low-resource settings. In this iteration of the ISN-GKHA, we sought to extend previous findings by assessing availability, accessibility, quality, and affordability of medicines, kidney replacement therapy (KRT), and conservative kidney management (CKM).

...

"Findings

The literature review used information on prevalence of chronic kidney disease from 161 countries. The global median prevalence of chronic kidney disease was 9·5% (IQR 5·9–11·7) with the highest prevalence in Eastern and Central Europe (12·8%, 11·9–14·1). For the survey analysis, responses received covered 167 (87%) of 191 countries, representing 97·4% (7·700 billion of 7·903 billion) of the world population. Chronic haemodialysis was available in 162 (98%) of 165 countries, chronic peritoneal dialysis in 130 (79%), and kidney transplantation in 116 (70%). However, 121 (74%) of 164 countries were able to provide KRT to more than 50% of people with kidney failure. Children did not have access to haemodialysis in 12 (19%) of 62 countries, peritoneal dialysis in three (6%) countries, or kidney transplantation in three (6%) countries. CKM (non-dialysis management of people with kidney failure chosen through shared decision making) was available in 87 (53%) of 165 countries. The annual median costs of KRT were: US$19 380 per person for haemodialysis, $18 959 for peritoneal dialysis, and $26 903 for the first year of kidney transplantation. Overall, 74 (45%) of 166 countries allocated public funding to provide free haemodialysis at the point of delivery; use of this funding scheme increased with country income level. The median global prevalence of nephrologists was 11·8 per million population (IQR 1·8–24·8) with an 80-fold difference between low-income and high-income countries. Differing degrees of health workforce shortages were reported across regions and country income levels. A quarter of countries had a national chronic kidney disease-specific strategy (41 [25%] of 162) and chronic kidney disease was recognised as a health priority in 78 (48%) of 162 countries.

(B) Incidence of deceased-donor kidney transplantation. (C) Incidence of living-donor kidney transplantation. (D) Incidence of pre-emptive kidney transplantation. pmp=per million population

Even in the U.S., we aren't able to supply enough transplantable kidneys for everyone who needs one. Domestic kidney exchange helps fill some of the gap, but the gap, and the resulting number of premature deaths, is still huge.  It's enough to make you think about global kidney exchange...

Global pacemaker retransplantation

 There are innovative approaches to global health care.  Here is one, that involves reusing pacemakers recovered from deceased donors and refurbished for use in countries where pacemakers are too expensive for wide use.  Unlike some of what we encounter in kidney transplants across borders, the legal bans that have to be overcome may not come from the war against the poor.  A careful clinical trial is underway. There is also an unregulated black market...

Here's the encouraging story from Helio.com:

After death, a new life for refurbished pacemakers in low-, middle-income countries, February 23, 2024

"Lack of access to pacemakers is a major challenge to the provision of CV health care in low- and middle-income countries; however, postmortem pacemaker utilization could offer an opportunity to deliver this needed care, according to Thomas Crawford, MD, an electrophysiologist and associate professor of internal medicine at University of Michigan Health and the medical director of My Heart Your Heart, a cardiac pacemaker reuse initiative at the University of Michigan Cardiovascular Center

...

"Crawford: The need is great. Each year, somewhere between 1 million and 2 million people worldwide die due to a lack of access to pacemakers and defibrillators. There is literature reflecting this. When you query pacemaker implantation data for the United States, it is roughly 800 pacemakers per 1 million population. When you query countries like, for example, Nigeria, it says four pacemakers per million. Quite a difference.

"Per capita gross domestic product is such that, in many countries, a pacemaker costs more than a person’s annual income.

...

"Healio: What are the regulations around using a refurbished pacemaker?

"Crawford: Pacemaker reuse is illegal in all jurisdictions. The FDA states that pacemaker reuse is an “objectionable practice.” We know we can do it, but we need to develop partnerships with other entities to give us credibility. One of those methods to do this is by engaging the government. FDA issues export permits for this type of activity. We created a protocol where we reprocess the device, working with Northeast Scientific, which provides the pacemaker cleaning and sterilization. We have received permission from the FDA to export them. We have to put a sticker on them saying “not for use in the United States.” We are doing this in countries in which governments will allow it. One of the limitations is needing a government letter from each of the recipient countries. We have about 12 countries now, and the collection of countries we are working with is purely accidental. It is not a normal methodological process. A lot of it is through contact with individuals and opportunities that arise.

...
"Healio: You are leading a randomized controlled trial called Project My Heart Your Heart: Pacemaker Reuse. What is the study design, and what do you and your colleagues hope to learn?

"Crawford: The objective of the clinical trial is to determine if pacemaker reutilization can be shown to be a safe means of delivering pacemakers to patients in low- and middle-income countries without resources. The target enrollment is 270 patients, all from outside the United States, who each have a class I indication for pacing and who attest that they do not have the ability to purchase a device on their own. They must consent to be randomly assigned to receive either a brand-new pacemaker, which we purchase, or a reprocessed pacemaker, for which we provide the leads and accessories. Donated devices are inspected according to specific protocols that evaluate physical and electrical suitability, including battery longevity, for future use. Devices deemed to be acceptable are shipped to a third-party vendor, Northeast Scientific, for disassembly, cleaning and re-sterilization. There will be about 130 participants in each arm. We will follow those patients and report any adverse events. The countries that have contributed patients include Kenya, Nigeria, Paraguay, Sierra Leone and Venezuela. We hope to soon begin enrolling patients in Mexico and Mozambique.

"I have had clinicians outside the U.S. who tell me they removed a pacemaker device, cleaned it, reprocessed it and then implanted it in someone else — but the government does not know about it. This practice does happen and it is not regulated in any way; patients and physicians know about it and keep it quiet. The difference with what we are doing and these other efforts is we bring it to a much higher level, because that is what the FDA requires. "

Global kidney exchange between Denmark and U.S.

 Here's a news story from North Carolina, home of one of the patient-donor pairs in the U.S.-Denmark kidney exchange, organized by the Alliance for Paired Kidney Donation (APKD).

Worldwide kidney transplant chain saves lives in Raleigh, Denmark, Colorado. by: Maggie Newland

"RALEIGH, N.C. (WNCN) — When a Raleigh musician needed a kidney, a friend of a friend offered to donate hers. The offer led to a kidney transplant chain stretching from the Triangle all the way to Denmark.

...

"Meanwhile, across the ocean, in Denmark, friends Peter Wichmann and Morton Berktoft were dealing with a similar issue. Wichmann wanted to donate his kidney to Berktoft, but they didn’t match either.

"Then something called a paired kidney exchange ended up helping all of them.  

"“It’s actually a Nobel prize-winning algorithm,” explained Krista Sweeney with AKPD. “They put these pairs into our system… We’re able to identify the best matches for each pair.”

"In this case, Kovacic donated her kidney to someone in Colorado. Their loved one donated a kidney to Berktoft, who flew to the U.S. for the surgery along with Wichmann, who donated a kidney to Adamo.

...

"Three months after the surgeries the donors and recipients are all doing well and got a chance to talk to each other in a virtual meeting.

...

“Even though the paired exchange wasn’t our initial plan it worked out so great for six people,” said Kovacic. “And three people’s lives to be saved.”

Kidney Paired Donation in Developing Countries: a Global Perspective

 Vivek Kute and his colleagues argue that one of the lessons from the developing world is that kidney exchange can save many lives, but may need to be organized differently in some ways than in the developed world.

Kidney Paired Donation in Developing Countries: a Global Perspective by Vivek B. Kute, Vidya A. Fleetwood, Sanshriti Chauhan, Hari Shankar Meshram, Yasar Caliskan, Chintalapati Varma, Halil Yazıcı, Özgür Akın Oto & Krista L. Lentine, Current Transplantation Reports (2023)  (here's a link that may provide better access]


Abstract

...

"Despite the advantages of KPD programs, they remain rare among developing nations, and the programs that exist have many differences with those of in developed countries. There is a paucity of literature and lack of published data on KPD from most of the developing nations. Expanding KPD programs may require the adoption of features and innovations of successful KPD programs. Cooperation with national and international societies should be encouraged to ensure endorsement and sharing of best practices.

Summary

KPD is in the initial stages or has not yet started in the majority of the emerging nations. But the logistics and strategies required to implement KPD in developing nations differ from other parts of the world. By learning from the KPD experience in developing countries and adapting to their unique needs, it should be possible to expand access to KPD to allow more transplants to happen for patients in need worldwide."

...

" Despite the advantages of KPD programs, they remain rare in the developing world, and the programs that exist have many differences with those of developed countries. Program structure is one of these differences: multi-center, regional, and national KPD programs (Swiss, Australia, Canada, Dutch, UK, USA) are more common in the developed than the developing world, whereas single center programs are more common

...

"kidney exchanges frequently take weeks to months to obtain legal permission in India despite the fact that only closely-related family members (i.e., parents, spouse, siblings, children, and grandparents) are allowed to donate a kidney [47].

...

"Protecting the privacy of a donor, including maintaining anonymity when requested, is common practice among developed countries but uncommon in developing nations. Anonymous allocation during KPD is a standard practice in the Netherlands, Sweden, and other parts of Europe, but this is not the case in countries such as India, Korea, and Romania [14, 48, 49]. In areas where anonymity is not maintained, the intended donor/recipient pair must meet and share medical information once a potential exchange is identified, but before formal allocation of pairs occurs. The original donor/ recipient pair may refuse the proposed exchange option for any reason and continue to be on the waitlist. In India, nonanonymous KPD allocation is standard practice and has the goal of increasing trust and transparency between the transplant team and the administrative team [14, 49]. Countries differ in philosophical approaches to optimizing trust and transparency, and objective data on most effective practices would benefit the global community."

Tomorrow I hope to have a few words to say about the equally unique situation in China.
