"Scraping poison off the bone": Transplants in China without organs from executed prisoners

 Following a long period in which the bulk of China's organ transplants used organs from executed prisoners, there have been steady efforts to create a system of voluntary deceased donation comparable to that in most of the world where transplants are done.

Global Times has the latest bit of that evolving story:

China’s organ donation to be more transparent under newly issued rules By Zhao Yusha and Zhang Yuying   Dec 15, 2023

"Chinese Premier Li Qiang has signed a decree of the State Council to unveil rules on human organ donation and transplantation, media reported on Thursday, with Chinese experts noting that the country’s organ donations will be more transparent under the regulation, which reflects great determination in China's organ donation reform. 

The newly issued rules, which will take effect on May 1, 2024, have been refined from the ones on human organ transplantation issued in 2007 to meet the demands of changing situations and ensure the healthy development of the cause, according to the Xinhua News Agency.

The rules strengthen the publicity and guidance of organ donation. Besides, the regulations stipulate that organ donation must adhere to the principles of voluntary and unpaid participation, and the conditions and procedures of donation should be improved based on the Civil Code. 

...

"China’s organ donations will be more transparent under the newly issued rules, Huang Jiefu, chairman of China Human Organ Donation and Transplantation Committee and chair of the China Organ Transplant Development Foundation Advisory Board, told the Global Times on Thursday.

"Huang noted that the revision of the rules shows the great determination in China's organ donation reform, which he described as scraping poison off the bone. “The regulations reflect the importance the Party and country attach to organ donation, which provides a strong legal guarantee for the high-quality development of organ donation cause.” 

"According to the rules, the application management of organ transplantation technologies should be improved to ensure medical quality. Specifically speaking, the rules define the conditions that medical institutions and practicing physicians must possess when engaging in organ transplantation, and require regular evaluation of the clinical application capabilities of relevant technologies in medical institutions. 

...

"In addition, the rules improve related provisions on legal liabilities and strengthen the punishment of malpractice in the field, Xinhua reported.

"Experts said the new rules call for more people to get involved in organ donations and transplants, and it is hoped that China's organ transplantation technology will spread to more countries in the future."

[The new regulations] "stipulate that patients whose spouses, direct blood relatives and other relatives have donated deceased organs can apply for organ transplantation , priority is given to them under the same conditions. 

...

"Ethical review requirements before organ harvesting will be refined, and the witnessing procedures for harvesting organs from deceased persons will be stipulated. Improve the cadaver organ distribution system, stipulate that the distribution of cadaver organs should meet medical needs, follow the principles of fairness, impartiality, and openness, and distribute uniformly through the distribution system established by the health department of the State Council. It is required to regularly announce the donation and distribution of cadaver organs and accept social supervision.

...

"In addition, relevant provisions on legal liability have been improved, penalties have been increased, and illegal activities in the field of organ donation and transplantation have been severely cracked down on.

The international market for squid (and how squid came to be calamari...)

China's fishing fleet plays a giant role in the international market for squid. The New Yorker has the story:

THE CRIMES BEHIND THE SEAFOOD YOU EAT.  China has invested heavily in an armada of far-flung fishing vessels, in part to extend its global influence. This maritime expansion has come at grave human cost.  By Ian Urbin in collaboration with the Outlaw Ocean Project.

"In the past few decades, partly in an effort to project its influence abroad, China has dramatically expanded its distant-water fishing fleet. Chinese firms now own or operate terminals in ninety-five foreign ports. China estimates that it has twenty-seven hundred distant-water fishing ships, though this figure does not include vessels in contested waters; public records and satellite imaging suggest that the fleet may be closer to sixty-five hundred ships. (The U.S. and the E.U., by contrast, have fewer than three hundred distant-water fishing vessels each.) 

...

" The country is largely unresponsive to international laws, and its fleet is the worst perpetrator of illegal fishing in the world, helping drive species to the brink of extinction. Its ships are also rife with labor trafficking, debt bondage, violence, criminal neglect, and death. “The human-rights abuses on these ships are happening on an industrial and global scale,” Steve Trent, the C.E.O. of the Environmental Justice Foundation, said.

...

"Vessels can now stay at sea for more than two years without returning to land. As a result, global seafood consumption has risen fivefold.

"Squid fishing, or jigging, in particular, has grown with American appetites. Until the early seventies, Americans consumed squid in tiny amounts, mostly at niche restaurants on the coasts. But as overfishing depleted fish stocks the federal government encouraged fishermen to shift their focus to squid, whose stocks were still robust. In 1974, a business-school student named Paul Kalikstein published a master’s thesis asserting that Americans would prefer squid if it were breaded and fried. Promoters suggested calling it “calamari,” the Italian word, which made it sound more like a gourmet dish. (“Squid” is thought to be a sailors’ variant of “squirt,” a reference to squid ink.) By the nineties, chain restaurants across the Midwest were serving squid. Today, Americans eat a hundred thousand tons a year.

...

"China has invested heavily in its fleet. The country now catches more than five billion pounds of seafood a year through distant-water fishing, the biggest portion of it squid. China’s seafood industry, which is estimated to be worth more than thirty-five billion dollars, accounts for a fifth of the international trade, and has helped create fifteen million jobs. The Chinese state owns much of the industry—including some twenty per cent of its squid ships—and oversees the rest through the Overseas Fisheries Association. Today, the nation consumes more than a third of the world’s fish."

Facial recognition software and autocracy

 Here's a somewhat chilling recent NBER paper:

Exporting the Surveillance State via Trade in AI  by Martin Beraja, Andrew Kao, David Y. Yang & Noam Yuchtman  WORKING PAPER 31676   DOI 10.3386/w31676  September 2023

We document three facts about the global diffusion of surveillance AI technology, and in particular, the role played by China. First, China has a comparative advantage in this technology. It is substantially more likely to export surveillance AI than other countries, and particularly so as compared to other frontier technologies. Second, autocracies and weak democracies are more likely to import surveillance AI from China. This bias is not observed in AI imports from the US or in imports of other frontier technologies from China. Third, autocracies and weak democracies are especially more likely to import China’s surveillance AI in years of domestic unrest. Such imports coincide with declines in domestic institutional quality more broadly. To the extent that China may be exporting its surveillance state via trade in AI, this can enhance and beget more autocracies abroad. This possibility challenges the view that economic integration is necessarily associated with the diffusion of liberal institutions.

Organ transplantation in China: in transition--and controversy about paying funeral costs

 I recently spoke at the CAST transplant conference in Hong Kong (see picture), and the underlying theme of my talk, and of many talks there, was the transition of transplantation in China, and what its future might hold.

Jie-Fu HUANG is the other speaker on Zoom (to my right and your left), and Haibo Wang is on the far left on stage.

Here are two of my opening slides (using 2021 data from the Global Observatory on Donation and Transplantation)


On the left, you see that, today, China and India already perform more kidney transplants than any country in the world except the U.S.  On the right, you see that, by virtue of their large populations, they accomplish this despite their quite low rates of transplants per million population, compared to the U.S. and countries in Europe.  So if China and India can raise their transplant rates to rates comparable to the U.S. and Europe, most of the transplants in the world will be done in Asia, and many many additional lives will be saved.

Note that China mostly transplants kidneys from deceased donors, while India mostly transplants kidneys from living donors. So they have different paths (and plenty of untapped potential) for raising donation and transplantation rates.  And their paths to their current positions have also been very different.

Here is a recent account reflecting China's recent progress:

Chen, Zhitao, Han, Ming, Dong, Yuqi, Zeng, Ping, Liao, Yuan, Wang, Tielong, et al. (2023). First Affiliated Hospital of Sun Yat-sen University, Guangzhou, People's Republic of China: 5-year Experience at a High-volume Donor and Recipient Liver Transplant Center. Transplantation, 107, 1855-1859. https://doi.org/10.1097/TP.0000000000004561

" In 1972, our center performed the first living donor kidney transplantation in China. Since then, kidney and liver transplant programs have evolved. By the beginning of the 21st century, organ transplantation had advanced, and clinical liver transplants have been performed successfully at the First Affiliated Hospital of Sun Yat-sen University.1

"Organ shortage has been a prominent feature at our institution as it has been around the world. Starting in the early 1980s, many organs had been procured from inmates on death rows. This unethical approach has been rightfully criticized by the worldwide community. As a consequence, the source of organs for transplants has solely been replaced by voluntary donations from Chinese citizens since January 1, 2015.

...

"Moreover, policies and methods for humanitarian aid to donor families were established. Those policies follow WHO guidelines while recognizing specific aspects of the Chinese culture. The State Ministry of Health and the Red Cross Society of China launched a pilot project on organ donation after the death of citizens in 2010 and established the China Organ Donation Committee. The principle of this pilot project was to learn from the experiences and standards in developed countries while recognizing national conditions and the social reality in China aiming to build an ethical and effective scientific organ donation and transplantation system.2

**********

In the same issue of Transplantation as the above article is this invited commentary by Ascher and Delmonico, both former Presidents of The Transplanation Society (of which Transplantation is the official journal). They largely approve of the effort China has made in transplants, but they have a big reservation.

Ascher, Nancy, MD, PhD & Delmonico, Francis. (2023). Organ Donation and Transplantation in China. Transplantation, 107, 1880-1882. https://doi.org/10.1097/TP.0000000000004562

"The date of 2015 is important for the review of any organ transplantation report from China because of the public proclamation in the media in 2015 prohibiting the use of organs from executed prisoners. Clinical transplantation articles antecedent to 2015 have been consistently rejected by Transplantation and the international community because the source of the transplanted organs was most often an incarcerated prisoner. China took a major step to condemn this practice publicly in 2015. However, because there is no law or regulation that prohibits this unethical practice, there has been ongoing concern that this practice may be continuing. Notwithstanding such a reality, there have been regulations that are citable and may be reflective of the changing experience of organ donation and transplantation in China that are consistent with the World Health Organization (WHO) Guiding Principles.

...

"WHAT CONTINUES TO BE OBJECTIONABLE

"The Chinese Red Cross is prominent in the organ donation process and a center of support for deceased donor families designated by the Red Cross as humanitarian aid to donor families.7 However, such humanitarian aid, although not limited to China, should not be misinterpreted to be an effort because it includes payment to elicit consent for donation. The Sun Yat-sen publication suggests that the Red Cross policies follow WHO guidelines while recognizing specific aspects of Chinese culture without elaboration as to the cultural details. A payment to donor families for funeral expenses or other monetary incentives should be recognized as a form of commercialization and would not comply with WHO guidelines."

**********

Some background may help put this objection in perspective. Doctors Delmonico and Ascher are prominent signatories of a declaration that payments to families of organ donors are crimes against humanity (as are payments to living donors, and both are declared comparable to transplanting organs from executed prisoners, and to be organ trafficking. See my 2017 post.)

So, they raise the question of whether saving many lives by increasing deceased donation in China will be justified if it involves paying funeral expenses of donors.  

My guess is that Chinese health authorities, thinking of the many lives to be saved, will think that this act of generosity to families of deceased donors will indeed be justified, taking account of (see above) "national conditions and the social reality in China aiming to build an ethical and effective scientific organ donation and transplantation system." 

Many people in China and elsewhere might even think that little if any justification is needed for generosity, particularly generosity to families of deceased donors, that is to families who are themselves generous.

Calligraphy fan: OR and Game Theory

 Haibo Wang visited and brought me a fan, with calligraphy from his dad in Chinese characters.


Alex Chan translates:

"What is written is “運籌帷幄 博弈天下”.   運籌 is logistics (運籌學 is operations research) 博弈is gaming (and 博弈論 is  game theory)." 

"And the translation for the whole phrase is something like: strategizing and gaming the world - this is how you might describe a general."

Organ transplants between Hong Kong and mainland China: the promise and the politics

 This is a followup post to an earlier post# about the first cross border transplant in China between the mainland and Hong Kong. That's been followed by some political tensions, as reported in this forthcoming article in the American Journal of Transplantation.

A plan to save lives: Hong Kong–mainland China second-tier mutual assistance allocation. The new program between the transplant communities plays out on a backdrop of controversy and historical tension  by Lara C. Pullen, PhD, Published:July 28, 2023DOI:https://doi.org/10.1016/j.ajt.2023.07.015

"Key points:

"The transplant communities of Hong Kong and mainland China have proposed a second-tier mutual assistance allocation program that some find controversial.

• Tensions between Hong Kong and mainland China have a long and deep history.

• In 2014, the Chinese government announced a stop to obtaining organs from executed prisoners.

• Transplantation in mainland China has rapidly evolved, and people monitoring the change report that data from 10 to 15 years ago does not reflect the country’s current system."

**********

The background:

In December, the South China Morning Post carried this story about a transplant involving an organ recovered on the mainland and transplanted into a baby in Hong Kong, which was apparently the first such  transplant to cross that border:

4-month-old Hong Kong girl suffering from heart failure receives successful transplant with donated organ from mainland China, in city’s first such arrangement by Cannix Yau

One of the subheadlines is "Health Bureau notes importation of organ met relevant regulations, and hospital officials say arrangement involving mainland might be repeated in future"

***

And here's the story in the China Daily:

Securing a new lease of life By Li Bingcun | HK EDITION | Updated: 2023-03-31 15:10

"Hong Kong and the Chinese mainland have successfully carried out the first-ever cross-boundary organ-sharing operation, saving the life of an infant. The feat caps the city’s strenuous efforts to create a standing mechanism in organ sharing with the mainland to save more lives. Li Bingcun reports from Hong Kong."

***

Apparently the discussion of closer cooperation between transplant authorities in Hong Kong and the mainland is politically fraught. 

Here's a story from the Global Times that refers to some pushback from the mainland:

First organ donation between mainland and HK saves 4-month old baby By Wan Hengyi

"the acceptable heart donation for Cleo requires a donor weighing between 4.5 kilograms and 13 kilograms, and the chances of a suitable donor appearing in Hong Kong are slim to none. 

...

"COTRS initiated the allocation of a donated heart of a child with brain death due to brain trauma in the mainland on December 15. As a very low-weight donor, no suitable recipients were found after multiple rounds of automatic matching with 1,153 patients on a national waiting list for heart transplants in the COTRS system. In the end, the medical assistance human organ-sharing plan between the Chinese mainland and Hong Kong was launched.

"Some netizens from the Chinese mainland asked why a baby from Hong Kong who has not lined up in the COTRS system can get a donated heart when there is a huge shortage of donated organs in the mainland.

"In response, the organ coordinator told the Global Times that the requirements for organ donation are extremely high, noting that all the prerequisites including the conditions of the donor and recipient, the time for the organ to be transported on the road and the preparation for surgery must reach the standards before the donation can be completed.

"The COTRS system has already gone through several rounds of matching, which is done automatically by computer without human intervention, said the organ coordinator. "

...

"As of the end of October 2022, a total of 42,500 donors had donated more than 126,300 large organs in China, according to Guo Yanhong, director of the medical emergency department of the NHC."

******

Here's a story from the Guardian, about political concerns on the Hong Kong side:

Hongkongers opt out of organ registry ‘amid fear of Chinese donations’      by Amy Hawkins

"Thousands of Hongkongers have opted out of the city’s organ donor registry, seemingly as a form of subtle protest against proposals to establish deeper medical ties with mainland China.

...

"The trigger appears to have been a life-saving operation carried out in December on a four-month-old baby girl in Hong Kong, who was in need of a heart transplant. When a local match could not be found, a heart was transferred from a child who had suffered brainstem death in mainland China.

...

"Since the baby’s heart transplant, authorities have discussed the idea of establishing a mutual assistance registry with mainland China to facilitate future donations. That would be yet another erosion of the boundary between China and Hong Kong, which was supposed to remain largely autonomous from Beijing until 2047.

"Earlier this month, local news outlet Ming Pao reported that there had been discussion on social media among Hongkongers who did not want their organs donated to patients in mainland China."

********

China has a population approaching 1.5 Billion people, and Hong Kong is a city of about 7.5 Million people, so my guess is that HK is too small to have an efficient self-contained transplant system, and could benefit from being integrated into the mainland's system.

Kidney Exchange in Hong Kong

While liver exchanges have been done for some time in Hong Kong, possibly the first kidney exchange  has recently been reported by China Daily:

Exchanging the hope of life By Li Bingcun | HK EDITION |  2023-06-16 

"It was the first time that paired kidney transplants had been carried out in the city. Following a pilot program launched in 2018, if a patient's family member is willing to donate a kidney to the patient but their conditions do not match, the family is allowed to make a cross-donation with another family in the same situation. Previously, organ donations from living donors could be made only by close blood relatives and spouses.

"In addition to kidney transfers, Hong Kong has accomplished several cross-family liver transplants since 2009 with special approvals made by the Human Organ Transplant Board on a case-by-case basis. Facing a severe shortage of organ donations, Hong Kong is drawing on overseas experiences to widen the scope of donations from living donors by trying to overcome restrictions concerning blood type and marriage, seeking greater matching possibilities to achieve more life-saving miracles.

"These attempts involve considerable efforts to update traditional mindsets, address the accompanying ethical and legal issues, and protect the safety and interests of donors and recipients to the fullest extent.

However, because of risks to donors, medical experts suggest that organ donations from living people should never be the first choice, and that the priority should be boosting people's willingness to register as organ donors, allowing organs to be reused after registered people die.

"Globally, such kidney exchange programs have been introduced in South Korea, the United States, the United Kingdom, Australia and Canada, with surgeries performed two decades ago.

"Besides paired donations, the US also allows "nondirected donations", which means a donor can donate his or her kidney to any compatible patient. The largest kidney swaps were completed in 2014, involving 70 participants. Some global exchange programs have also carried out transnational kidney donations.

"With Hong Kong's relatively low organ-donation rate, more than 2,000 local residents are awaiting kidney transplants each year, with an average waiting time of about five years, and the longest 29 years. The number of kidney donations from living family members is less than 20 annually, while the number of cadaveric donations declined from 84 in 2012 to 45 in 2022.

"Although renal-failure patients can receive dialysis to sustain their lives, organ transplantation is still the best option. Moreover, the quality of organs of living donors is considered better than that of cadaveric organs.

"To offer patients another option, Hong Kong had been preparing to introduce the paired kidney donation (PKD) program since 2012, according to Chau Ka-foon, former co-chairperson of the Hospital Authority's Paired Kidney Donation Working Group. After extensive discussions, the city revised the law in 2018 and officially launched the program.

...

"two families that were successfully matched in 2020 canceled their planned surgeries due to personal concerns. Chau explains that the families might have worried that the organ received was of lower quality than the one they donated. It would also be a heavy blow if a family donating a kidney were unable to receive one if an operation were to fail.

...

"Attempts to swap organs among strangers have also encountered complex legal and technical problems.

"In Hong Kong's first-ever cross-family transplant in 2009, the medical team made a lot of efforts explaining to the Human Organ Transplant Board that the operation wasn't a transaction. "We repeatedly emphasized that the two families did not intend to exchange organs. It was simply the medical workers' proposal to raise the success rate of organ transplants," says Lo Chung-mau, chief surgeon of the operation and also director of the liver transplantation center at Queen Mary Hospital at that time.

...

"The 2019 social unrest and the following COVID-19 pandemic presented even greater challenges for Hong Kong's PKD program. In 2021, there were 26 eligible families in the city's organ matching pool.

"The Hospital Authority expects the number of participating families to climb to 50 to 100 in a few years. It will consider expanding the program to liver donations and collaborating with overseas matching pools. Chau hopes that kidney swaps will not be limited to just two families, and that multiple swaps among several families will be allowed to increase the chances of matching.

...

"Wang Haibo, a member of China's National Organ Donation and Transplantation Committee, says the pair-donation program is worth looking into and being discussed. The mainland is also conducting clinical research on paired-kidney donations. Alvin Roth, who won the 2012 Nobel Memorial Prize in Economic Sciences and developed a global kidney-exchange program, visited China before the COVID-19 pandemic to seek collaboration in this area, he recalls.

"Wang says both Hong Kong's and the mainland's organ donation rates still lag far behind those of developed economies. "They have reached a plateau and have made relatively adequate utilization of organ donations from the deceased. We have much room to develop in this regard."

"He says that while officials explore innovative approaches concerning living-organ donations, the priority should still focus on how to boost people's willingness to register as organ donors and better utilize the organs. "These are the so-called 'low hanging fruit'. It would be wise to concentrate our limited resources on the most rewarded option."
