In China, Prisoners of Conscience Are Being Murdered for Their Organs to Fuel Transplant Tourism
A somber photo of the Great Wall of China.
Organ transplantation can dramatically improve or save lives. A heart transplant can literally give a person a new lease of life, while a kidney transplant frees the recipient from lengthy spells on dialysis.
A people's tribunal in London has recently found that in China, organs are sourced from prisoners of conscience who are killed on demand to fuel the lucrative organ transplantation market.
To protect the integrity of organ transplantation, there are strict ethical guidelines. When organs are sourced from deceased persons, the donation must be voluntary, donors must die naturally before any organs are taken, and death must not be hastened to provide organs. These ethical guidelines protect donors and provide assurance to transplant recipients that their organs have been sourced ethically.
However, not all countries follow these ethical guidelines. A people's tribunal in London has recently found that in China, organs are sourced from prisoners of conscience who are killed on demand to fuel the lucrative organ transplantation market. This conclusion, reported at the United Nations Human Rights Council on September 24, was not reached lightly.
The independent China Tribunal, made up of four human rights lawyers, one surgeon with transplant experience, an academic who specialises in China studies and a businessman with human rights interests, spent over a year looking at written materials and heard evidence from over 50 witnesses in five days of hearings. Their grim conclusion, that prisoners of conscience are murdered for their organs, confirms the findings of earlier investigations.
Questions first arose over China's transplant system when the numbers of transplants rose dramatically after 2000. Transplant capacity rapidly increased; new infrastructure was built and staff were trained. Hospital websites offered livers, hearts and kidneys available in a matter of days or weeks, for a price. Foreigners were encouraged to come to China to avoid lengthy transplant waiting lists in their home countries.
At the time, it was a mystery as to how China had a ready supply of organs, despite having no volunteer donation system. Eventually, in 2006, the Chinese government stated that organs were removed from prisoners who had been found guilty and sentenced to the death penalty. But this explanation did not ring true. Death row prisoners often have poor health, including high rates of infectious diseases, making them poor candidates for donation. By contrast, the organs offered for sale were promised to be healthy.
In 2006, the first clues about the source of the organs emerged. A woman called Annie reported that her surgeon husband had been present during organ removal from Falun Gong practitioners who were still breathing as the scalpels cut into them. A subsequent investigation by two Canadian human rights lawyers examined multiple sources of evidence, concluding that murdered Falun Gong practitioners were indeed the source of the organs.
The evidence included testimony from practitioners who had been imprisoned, tortured, and later released. During imprisonment, many practitioners reported blood and other medical tests examining the health of their organs—tests that were not performed on any other prisoners. Phone calls made to Chinese hospitals by investigators posing as patients were offered rapid access to fresh organs from Falun Gong practitioners. The organs were guaranteed to be healthy, as the practice forbids smoking tobacco and drinking alcohol.
Since 2006, evidence has continued to accumulate. China has a huge transplant industry and no plausible source of voluntary organ donations. Unlike the rest of the world, Chinese waiting times remain very short. Foreigners continue to come to China to avoid lengthy waiting lists. Prisoners of conscience, including Tibetans and Uyghurs as well as Falun Gong practitioners, are still being imprisoned and medically tested.
The Chinese government continues to deny these crimes, claiming that there is a volunteer donor system in place.
The China Tribunal heard from Uyghur witnesses who had recently been inside the notorious labour camps (also called "re-education" centers) in Xin Xiang. The witnesses reported terrible conditions, including overcrowding and torture, and were forced to have medical examinations. They saw other prisoners disappear without explanation following similar medical tests. As recently as 2018, doctors in Chinese hospitals were promising potential patients healthy Falun Gong organs in taped phone calls.
The Chinese government continues to deny these crimes, claiming that there is a volunteer donor system in place. In the Chinese system, prisoners are counted as volunteers.
China's forced organ harvesting from prisoners of conscience has international implications. A recent study found that most published Chinese transplant research is based on organs sourced from prisoners. International ethical guidance prohibits taking organs from prisoners and prohibits publication of research based on transplanted material from prisoners. The authors of that study called for retractions of the papers, some of which are in well-known scientific journals. So far Transplantation and PLOS One are among the journals that have already retracted over twenty articles in response. On questioning from the editors, the authors of the papers failed to respond or could not verify that the organs in the transplant research came from volunteers.
The international community has a moral obligation to act together to stop forced organ harvesting in China.
The China Tribunal concluded that forced organ harvesting remains China's main source of transplant organs. In their view, the commission of Crimes Against Humanity against the Uyghurs and Falun Gong has been proved beyond reasonable doubt. By their actions, the Chinese government has turned a life-saving altruistic practice into our worst nightmare. The international community has a moral obligation to act together to stop forced organ harvesting in China, and end these crimes against humanity.
Did researchers finally find a way to lick COVID?
A professor of medicine at the University of Michigan is researching whether lactoferrin, which is found in dairy products such as ice cream, can help to prevent COVID-19 infections.
Already vaccinated and want more protection from COVID-19? A protein found in ice cream could help, some research suggests, though there are a bunch of caveats.
The protein, called lactoferrin, is found in the milk of mammals and thus in dairy products, including ice cream. It has astounding antiviral properties that have been taken for granted and remain largely unexplored because it is a natural product, meaning that it cannot be patented and exploited by pharmaceutical companies.
Still, a few researchers in Europe and elsewhere have sought to better understand the compound.
Jonathan Sexton runs a drug screening program at the University of Michigan where cells are infected with a pathogen and then exposed to a library of the thousands of small molecule drug compounds – which can enter the body more easily than drugs with heavier molecules – approved by the FDA. In addition, the library includes compounds that passed phase 1 safety studies but later proved ineffective against the targeted disease. Each drug is dissolved in a solvent for exposure to the cells in the laborious testing process made feasible by robotic automation.
When COVID hit, researchers scrambled to identify any approved drug that might help fight the infection. Sexton decided to screen the drug library as well as some dietary supplements against SARS-CoV-2, the virus that causes the disease. Sexton says that the grunt work fell to Jesse Wotring, “a very talented PhD student,” who pulled lactoferrin off the shelf. But the regular solvent used in the testing process would destroy the protein, so he had to take another approach and do all the work by hand.
“We were agnostic,” says Sexton, who didn't have a strong interest in lactoferrin or any of the other compounds in the library, but the data was quite clear; lactoferrin “consistently produced the best efficacy...it was the absolute home run.” The findings were published in separate papers last year and in February.
It turns out that lactoferrin has several different mechanisms of action against SARS-CoV-2, inhibiting the virus from entering cells, moving around within them and replicating. Lactoferrin also modulates the overall immune response, which makes it difficult for the virus to simultaneously mutate resistance to the protein at every step of replication. “It has broad efficacy against every [SARS-CoV-2] variant that we've tested,” he says.
From bench to bedside
Sexton's initial interest was to develop a drug for the acute phase of COVID infection, to treat a hospitalized patient or prevent that hospitalization. But with the quick approval of vaccines and drugs to treat the disease, he increasingly focused on ways to better prevent infection and inhibit spread of the virus.
“If you can get lactoferrin to persist in your upper GI tract, then it may very well prevent the primary infection, and that's what we're really interested in.” He reasoned that a chewing gum formula might release enough lactoferrin into the mucosal tissue of the mouth and upper airways to inhibit replication and give the immune system a chance to knock out the virus before it can establish a foothold. It could also reduce the amount of virus spread through talking.
To get enough lactoferrin to have a possible beneficial effect, one would have to drink gallons of milk a day, “and that would have other undesirable consequences, like getting extremely obese,” says Sexton. Obesity is one of the leading risk factors for severe COVID disease.
Testing that theory has been difficult. The easiest way would be a “challenge trial,” where volunteers take the drug, or in this case gum, are exposed to the pathogen, and protection is measured. Some COVID challenge studies have been conducted in Europe but the FDA remains hesitant to allow such a study in the U.S. A traditional prevention study would be like a vaccine trial, involving thousands, perhaps tens of thousands of volunteers over a period of months or years, and it would be very expensive. No one has stepped forward to foot the bill.
So the next step for Sexton is a clinical trial of newly diagnosed COVID patients who will be given standard of care treatment, and layered on top of that they will receive either lactoferrin, probably in pill form, or a placebo. He has identified initial funding. “We would study their viral load over time as well as their symptoms.”
One issue the FDA is grappling with in considering the proposed trial is that it typically decides whether to approve drugs from a factory by applying a rigorous standard, called good manufacturing practices, while food products, which are the source of lactoferrin, are produced under somewhat different standards. The agency still has not finalized rules on how to deal with natural products used as drugs, such as fecal transplants, convalescent plasma, or medical marijuana.
Sexton is frustrated by the delay because lactoferrin derived from bovine milk whey has been used for many decades as a protein supplement by athletes, it is a large component of most infant formula, and the largest number of clinical studies of lactoferrin involve premature infants. There is no question of its safety, he says.
Do it yourself
So what can you do while waiting for regulatory wheels to spin and clinical trial data to be generated?
Could a dose of Ben & Jerry's provide some protection against SARS-CoV-2?
Sexton chuckles at the suggestion. He supposes it couldn't hurt. But to get enough lactoferrin to have a possible beneficial effect, one would have to drink gallons of milk a day, “and that would have other undesirable consequences, like getting extremely obese.” Obesity is one of the leading risk factors for severe COVID disease.
Pseudo-milk products made from soy, almonds, oats, or other plant products do not contain lactoferrin; it has to come from a teat. So that rules them out.
Whey-based protein shakes might be a useful way to add lactoferrin to the diet.
Probably the best option is to take conventional gelatin capsules of lactoferrin that are widely available wherever supplements are sold. Sexton calculates that about a gram a day, four 250 milligram capsules, should do it. He advises two in the morning and two a night. “You really want to take them on an empty stomach...your stomach treats [the lactoferrin protein] like it would a steak” and chops it for absorption in the intestine, which you do not want. About 70 percent of lactoferrin can get through an empty stomach, but eating food cranks up digestive gastric acids and the amount of intact lactoferrin that gets through to the gut plummets.
Sexton cautions, “We have not determined clinical efficacy yet,” and he is not offering advice as a physician, but in the spirit of harm reduction, he realizes that some people are going to try things that might help them. Lactoferrin “is remarkably safe. And so people have to make their own decisions about what they are willing to take and what they are not,” he says.
In today's episode, Leaps.org interviews Camila dos Santos, a molecular biologist at Cold Spring Harbor Lab, about her research on breasts and what makes them unique compared to any other part of the body.
My guest today for the Making Sense of Science podcast is Camila dos Santos, associate professor at Cold Spring Harbor Lab, who is a leading researcher of the inner lives of human mammary glands, more commonly known as breasts. These organs are unlike any other because throughout life they undergo numerous changes, first in puberty, then during pregnancies and lactation periods, and finally at the end of the cycle, when babies are weaned. A complex interplay of hormones governs these processes, in some cases increasing the risk of breast cancer and sometimes lowering it. Witnessing the molecular mechanics behind these processes in humans is not possible, so instead Dos Santos studies organoids—the clumps of breast cells donated by patients who undergo breast reduction surgeries or biopsies.
Show notes:
2:52 In response to hormones that arise during puberty, the breast cells grow and become more specialized, preparing the tissue for making milk.
7:53 How do breast cells know when to produce milk? It’s all governed by chemical messaging in the body. When the baby is born, the brain will release the hormone called oxytocin, which will make the breast cells contract and release the milk.
12:40 Breast resident immune cells are including T-cells and B-cells, but because they live inside the breast tissue their functions differ from the immune cells in other parts of the body,
17:00 With organoids—dimensional clumps of cells that are cultured in a dish—it is possible to visualize and study how these cells produce milk.
21:50 Women who are pregnant later in life are more likely to require medical intervention to breastfeed. Scientists are trying to understand the fundamental reasons why it happens.
26:10 Breast cancer has many risks factors. Generic mutations play a big role. All of us have the BRCA genes, but it is the alternation in the DNA sequence of the BRCA gene that can increase the predisposition to breast cancer. Aging and menopause are the risk factors for breast cancer, and so are pregnancies.
29:22 Women that are pregnant before the age of 20 to 25, have a decreased risk of breast cancer. And the hypothesis here is that during pregnancy breast cells more specialized, as specialized cells, they have a limited lifespan. It's more likely that they die before they turn into cancer.
33:08 Organoids are giving scientists an opportunity to practice personalized medicine. Scientists can test drugs on organoids taken from a patient to identify the most efficient treatment protocol.
