#Organ Transplantation

[macgyvermedical]

If someone got an organ transplant from an identical twin, would they need immunosuppressants like most transplant recipients?

Like, the reason people need immunosuppressants if they’ve had a transplant is because the transplanted organ has different dna cuz it’s from another person, so the immune system pings it as foreign and attacks it. Right?

But if the organ is from an identical twin, that’s the same dna, so….?

You're right- they would not need immunosuppresant drugs because the body would recognize the tissue as itself and not attack it.

In fact, the first successful kidney transplant was between identical twins in 1954. At the time it was very well studied that homografts (transplants between the same species) were almost universally rejected, and there was no way to suppress immune function or prevent rejection in these cases unless the donor and recipient were identical twins.

The first methods for immunosuppression mostly involved radiation, and while these were occasionally successful, they were much more often not successful. The first successful immunosuppressive drug regimen came out in 1963, a combination of prednisone and azathioprine, increasing the survival rate to 70% at one year post surgery.

In 1976 the first single immunosuppressive drug was introduced- cyclosporine. Even better results occurred when mixed with prednisone. In 1989, tacrolimus became the new standard anti-rejection medication, since it was less toxic and more potent than cyclosporine.

(edited sprint piece, 500 words, partly inspired by this book & paper)

The ice chest sat next to the hotel bed, covering a hole in the three layers of plastic wrap. He looked at it while the surgeon prepared, and hoped she wouldn't do any more checks to see if he was sure.

Even he'd assumed it was insomnia until he'd noticed mirrors had a color. It was a putrid color, at that - a higher octave of beige, only more damnably bright than the others.

"There aren't any medical texts for this, of course," she explained, shrugging off a layer of baggy casualwear and revealing full scrubs with plastic gloves taped to them. "It's a bit like those marriage drive-thrus in Vegas. Do they still have those? Anyway, you'll want to avoid doing any physicals from now on."

At night, stars had become suns again, while moonlight smeared the air and made it into fog. The moon itself didn't wane for him, but when its light was fainter it became almost tiger-striped with infrareds that rhymed with orange and green.

Next had come the clicking from the outdoors, a bomb or a loom hushed only by the rain. The sound of more letters being forced into his box in the lobby by someone cursing under their breath. Spiders became hydraulic and pistoning, snapped branches became wet telegraphs, and a universe of tiny, churning mouths vibrated the concrete under his feet.

The cravings had clarified the rest.

In the hotel room he laid back - sparing the details - and stared at the popcorn ceiling, thinking distantly of canopic jars. It was a wonder to him that this, this alone, should be so sensationless.

When the work has halfway done the ice chest was opened and gave a long, droning sigh as the surgeon lifted four containers and twisted four seals. For him it was hard to tell them apart except for size, but each smelled like mud or railroads or lifelong, prickling fear.

The group had already told him that rabbit, elk, pig and falcon were the traditional hearts for starting someone off. They'd also given him a warning, that his life depended on knowing which things kept and which would go sour. Which, he suspected, was just their segue to telling him he'd be paying in favors and not cash.

Rabbit, elk, pig, falcon. There was room for them, now, and as each was attached and resumed its operation he felt more - awake? The present contracted and expanded in the same motion, somehow - finer-grained but across a broader surface. All four beat in separate rhythms, syncopating in pairs and flirting in triplets until they joined in a crescendo on the half-hour mark.

"And - that's it?" he asked as the surgeon closed him up.

She placed the sewing needle between her teeth and made a 'so-so' gesture with her hand. "Reason these are standard is they go bad in about five years. Make nice with the right people and show you keep your favors and that won't be a problem. If that's not you, figure something out."

"Is stuff like this how you do it?" he asked.

She shook her head. "I made friends with the Order of St. Hubertus."

She declined to elaborate on that.

Might I also propose DNR+ for those who want to maintain the ability to donate organs!

A code status is what you want the hospital to do if your heart or breathing stops, and we've got two basic options: full code which means we do EVERYTHING and Do Not Resuscitate or DNR which means we do less than everything. There's like little add-ons like intubated or not intubated, or blood products or no blood products, but that's basic gist of it. Do you want us to try everything we can to save your life or if your heart stops, is that it? And then we take that information and put it in your chart and make it very prominent in case we need to find it quickly in an emergency. Jane Doe, 72 years old, DNR. John Whatsisname, 49 years old, full code. Like that.

Anyway I'd like to propose a third code status that we'll call "DNR!!!" This is when you not only don't want heroic measures to extend your life, you are so excited to die. I thought of this recently when getting report on a patient, and the day nurse talking to me was like, "Alice Smith, 80 years old, DNR and she will tell you that herself." And I was like, "I don't think code status is gonna come up organically," and the nurse was like, "It won't, but she'll tell you anyway." And then I introduced myself to the patient, and like three minutes in as we're talking about pain meds, she goes, "and by the way, when I'm dead, I'm DEAD. Don't be bringing me back! Every woman in my family has lived past 90, and I'm here to break that tradition! NO one needs to live that long, and I certainly don't, and frankly it's indecent for me to have made it this far. God willing the reaper will come for me any day now. I would never take actions to make him come sooner, but I'm not moving that fast and he is DAWDLING. Disgusting. No work ethic these days. And don't bother with a grave, just chuck me out the window and let the birds at me."

And I'm like "so is that a no to the tylenol"

And she was like "oh no, I'd love some tylenol and a warm blanket too. Now look at me. I've done everything I could possibly want to do in this world and quite a few things I didn't want to do, and personally I don't think I should have to keep doing things. I'd also love a cranberry juice."

Anyway. DNR!! I'm sorry to say she made it through the night completely unscathed.

Several countries, including Pakistan, Egypt, Bangladesh, India, Turkey, the Philippines and China, have been identified as centres of organ trafficking, but the trade in organs is a transnational operation. In its 2018 Global Report for Trafficking in Persons, the United Nations Office on Drugs and Crime identified more than 700 cases of organ trafficking, the majority in the Middle East and north Africa. A 2021 Interpol report claimed that organ trafficking was of particular concern in north and west Africa, “where impoverished communities and displaced populations are at greater risk of exploitation”.

According to the Global Observatory on Donation and Transplantation (GODT), only 10% of the global demand for transplants is met each year. Increased demand for kidney transplants, in particular, has been exacerbated by a shortage of altruistic donations and limited access to transplant services. This has led to an increased dependence on criminal networks that obtain organs from vulnerable individuals.

There is a black market for organs including kidneys, corneas and liver lobes. Rising demand for kidneys is partly a result of the spread of so-called diseases of affluence – diabetes, hypertension, obesity – and the subsequent rise in kidney failure. According to the charity Kidney Care, in the UK, the waiting list for a kidney transplant has increased dramatically since the pandemic. Consequently, more people are travelling overseas for transplant surgery. In many countries that attract transplant tourists, kidneys are sourced from the bodies of the poor and disenfranchised.

As a legal academic, I have been investigating the global trade in organs since 2014. Over the past 10 years, I have spoken to 43 people from Sudan, South Sudan and Eritrea who sold a kidney out of economic necessity. In most cases, people were targeted by criminal groups because of their precarious status as asylum seekers, refugees or undocumented migrants. Most were not paid what they were promised. Some were paid nothing. Doubly criminalised, as illegal migrants and organ sellers, they were in no position to negotiate a price, or to ensure they got paid the agreed amount. Because of their precarious legal status they were also less likely to report abuse to the authorities.

In the absence of legal pathways to migration, many had sold their kidneys after they had been arrested, detained and in some cases deported back to countries where their lives were under threat. Most had opted to avoid refugee camps, describing them as “prisons” and “death camps” where people go to die. They were disillusioned with the United Nations Refugee Agency (UNHCR). It was better to risk crossing the Sahara, Yonas told me, than to live under permanent surveillance, captive and dependent on a broken asylum system. Many, like Yonas, had expended all their resources trying to reach Europe and claim asylum. Categorised as illegal and pushed to the margins of society, they were exposed to exploitation of different kinds.

The illicit networks that supply organ markets depend on the close cooperation of medical doctors. Criminal intermediaries are involved in the negotiation of fees, and the preparation of official-looking paperwork presented as evidence of informed consent to an altruistic donation. These brokers, who connect sick patients with impoverished and vulnerable “donors”, also form long-term partnerships with medical professionals. Without the involvement of surgeons who perform illegal transplants for profit, the trade in organs would cease to exist.

In March 2023, the UK tried its first organ-trafficking case. A Nigerian politician, his wife and their broker were found guilty of conspiring to bring a man to the UK from Lagos to obtain his kidney for transplant. The judge said in sentencing: “The trafficking of people across international borders to harvest their organs is a form of slavery. It treats human beings, and their body parts, as commodities to be bought and sold. It is a trade that preys on human poverty, misery and desperation.” Unfortunately, as war and climate crisis displaces more people, there is no shortage of desperate people to prey on.

Transplants India bridges this financial gap and gives hope and a chance at life to those who would otherwise be left helpless.

Empowering the Economically Challenged

Affording an organ transplant is expensive. Patients who cannot secure finances mostly die because their health will continue deteriorating without a transplant. It not only financially drains the patients but devastates their families, rendering them in further poverty and despair. This overall critical issue is recognised by Transplants India, which is working tirelessly to make sure that no financial barriers come in the way of lifesaving medical procedures.

The Power of Your Donations

Transplants India relies upon generous donations to continue its great work. Any donation of funds can make an enormous difference in the life of someone who may be suffering from any life-threatening illness. Contributions enable patients to afford themselves health and happiness. All donations made to Transplants India are 80G compliant. Hence, tax-deductible and secure organisations appeal to one and all for donations and support to the cause to give many, many a second chance at life.

The Life-Saving Impact of Organ Donation

Besides monetary donations, organ donation is the area of work that is emphasised at Transplants India. One person can save up to eight lives by becoming an organ donor. Organ donation helps people make a significant contribution to society and creates a difference that can be remembered. Transplants India provides those interested in pledging organs with the proper resources and support to put a culture of gifting and saving lives into action and impacting Social Responsibility (CSR) Tie-ups.

Corporate Social Responsibility Saving Lives

Transplants India also seeks support from corporations through its CSR activities. An association with Transplants India will make these corporate houses vital in bringing financial support to people who are in dire need of organ transplant operations. Such associations save lives, enhance the corporate image, and discharge social responsibility. Participating in the noble cause of Transplants India facilitates these corporate houses to have a mark in society through an illustrious gesture of CSR participation.

Conclusion

Transplants India has been the epitome of gesture, compassion, and community support. Giving many people hope for life, and a chance to live a new life by helping them with financial constraints related to organ transplantation, donations, organ pledging, and CSR collaborations continue to bring about wide-ranging differences and make sure that in the very near future, financial constraints will not be the ones deciding the fate of those in need of lifesaving transplants.

I'm thinking about a master's degree in transplant sciences and shit like this is why. It's so fucking fascinating!!!

[reasonsforhope]

"The first modern attempt at transferring a uterus from one human to another occurred at the turn of the millennium. But surgeons had to remove the organ, which had become necrotic, 99 days later. The first successful transplant was performed in 2011 — but even then, the recipient wasn’t immediately able to get pregnant and deliver a baby. It took three more years for the first person in the world with a transplanted uterus to give birth. 

More than 70 such babies have been born globally in the decade since. “It’s a complete new world,” said Giuliano Testa, chief of abdominal transplant at Baylor University Medical Center.

Almost a third of those babies — 22 and counting — have been born in Dallas at Baylor. On Thursday, Testa and his team published a major cohort study in JAMA analyzing the results from the program’s first 20 patients. All women were of reproductive age and had no uterus (most having been born without one), but had at least one functioning ovary. Most of the uteri came from living donors, but two came from deceased donors.

Fourteen women had successful transplants, all of whom were able to have at least one baby.  

“That success rate is extraordinary, and I want that to get out there,” said Liza Johannesson, the medical director of uterus transplants at Baylor, who works with Testa and co-authored the study. “We want this to be an option for all women out there that need it.”

Six patients had transplant failures, all within two weeks of the procedure. Part of the problem may have been a learning curve: The study initially included only 10 patients, and five of the six with failed transplants were in that first group. These were “technical” failures, Testa said, involving aspects of the surgery such as how surgeons connected the organ’s blood vessels, what material was used for sutures, and selecting a uterus that would work well in a transplant. 

The team saw only one transplant fail in the second group of 10 people, the researchers said. All 20 transplants took place between September 2016 and August 2019.

Only one other cohort study has previously been published on uterus transplants, in 2022. A Swedish team, which included Johannesson before she moved to Baylor, performed seven successful transplants out of nine attempts. Six women, including the first transplant recipient to ever deliver a baby back in 2014, gave birth.

“It’s hard to extract data from that, because they were the first ones that did it,” Johannesson said. “This is the first time we can actually see the safety and efficacy of this procedure properly.”

So far, the signs are good: High success rates for transplants and live births, safe and healthy children so far, and early signs that immunosuppressants — typically given to transplant recipients so their bodies don’t reject the new organ — may not cause long-term harm, the researchers said. (The uterine transplants are removed after recipients no longer need them to deliver children.) And the Baylor team has figured out how to identify the right uterus for transfer: It should be from a donor who has had a baby before, is premenopausal, and, of course, who matches the blood type of the recipient, Testa said...

“They’ve really embraced the idea of practicing improvement as you go along, to understand how to make this safer or more effective. And that’s reflected in the results,” said Jessica Walter, an assistant professor of reproductive endocrinology and infertility at Northwestern University Feinberg School of Medicine, who co-authored an editorial on the research in JAMA...

Walter was a skeptic herself when she first learned about uterine transplants. The procedure seemed invasive and complicated. But she did her fellowship training at Penn Medicine, home to one of just four programs in the U.S. doing uterine transplants. 

“The firsts — the first time the patient received a transplant, the first time she got her period after the transplant, the positive pregnancy test,” Walter said. “Immersing myself in the science, the patients, the practitioners, and researchers — it really changed my opinion that this is science, and this is an innovation like anything else.” ...

Many transgender women are hopeful that uterine transplants might someday be available for them, but it’s likely a far-off possibility. Scientists need to rewind and do animal studies on how a uterus might fare in a different “hormonal milieu” before doing any clinical trials of the procedure with trans people, Wagner said.

Among cisgender women, more long-term research is still needed on the donors, recipients, and the children they have, experts said.

“We want other centers to start up,” Johannesson said. “Our main goal is to publish all of our data, as much as we can.”"

"Ensuring Fairness: High Court Directs Reconsideration of Transplant Decision"

J. Rajkumar v. The Authorization Committee Transplantation

W.P. 13642/2024 & WMP 14806 & 14807 / 2024

Before the High Court of Madras

Heard by Hon’ble Mr. Justice G R Swaminathan J

Order: The High Court allowed the Writ Petition of the Petitioner also set aside the rejection order of the Authorization Committee Transplantation The Committee / first respondent was directed to re-consider and pass an appropriate order within three weeks from the date of receipt of a copy of the order.

Judgment pronounced on 31.05.2024

Background

Writ Petition under Article 226 of the Constitution of India was filed for the calling of the records of the 1st respondent whereby the authorization committee rejected the petitioner's application for transplantation of Human Organ and to quash the rejection order and direct the 1st respondent to approve the petitioner's application/grant/approval/NOC to the petitioner for his kidney transplantation.

Facts:

1.      The Petitioner aged about 30 years was suffering from chronic kidney disease and a nephrologist had advised him for a kidney transplant. His wife wanted to donate her kidney but because of medical incompatibility transplantation couldn’t happen. Offers were made by other relatives as well but due to incompatibility factors transplantation couldn’t take place.

2.      A known of the family Mrs. Radhika offered to donate her kidney and it was found compatible however, the Authorization Committee Transplant rejected her offer as she was not a relative of the Petitioner.

Contention of the petitioner & the donor

1.      The kidney is offered out of love and affection and for the well-being of the petitioner’s family and there is no economic consideration to it.

Contention of the Government Counsel

1.      The Court shouldn’t interfere in the rejection order of the Authorization Committee Transplantation as the petitioner has the remedy of Appeal as provided under Section 17 of the Transplantation of Human Organs and Tissues Act, 1994.

Observation of the Court

1.      The refusal by hospitals in the State of Tamil Nadu to perform transplants concerning unrelated donors is illegal.

2.      The transplants from non-near relative donors is contemplated under Section 9(3) of the Transplantation of Human Organs and Tissues Act, 1994, and Rules 14 and 19 of the Transplantation of Human Organs and Tissues Rules, 2014 prescribing the procedure

3.      The Form 11 application submitted by the petitioner and the prospective donor was rejected by assigning the following reason “photo evidence and statement are grossly contradictory.”

4.      The opportunity for a personal hearing must be given. If an adverse order is passed, the rights of the patient is at stake. That is why, it is necessary to comply with the principles of natural justice. If any doubt occurs in the minds of the committee members, the applicants must be put on notice and allowed to explain.

5.      The petitioner was not given any opportunity to explain the contradiction noticed by the committee. There has been a gross violation of the principles of natural justice.

6.      The statement made by the prospective donor that he/she is coming forward to donate the organ out of altruism cannot be questioned unless there is definite material to show the passing of consideration. In this case, the minutes do not indicate the existence of commercial dealings between the parties.

The Body is a Big Place - Helen Pynor and Peta Clancy

"The Body is a Big Place is a large-scale, immersive installation developed through collaboration between artists and scientists. The work explores organ transplantation and the ambiguous thresholds between life and death, revealing the process of death as an extended durational process, rather than an event that occurs in a single moment in time. The work’s title refers to the capacity for parts of the body to traverse vast geographic, temporal and interpersonal distances during organ transplantation processes. As part of the installation a fully functioning heart perfusion system was used to reanimate to a beating state a pair of fresh pig hearts during 2 live performances. Rather than sensationalising these events, the artists sought to encourage empathic responses from viewers, opening up the possibility of a deeper awareness of viewers’ own interiors. Performers in the work’s projected underwater video sequences were members of the organ transplant community in Melbourne, individuals who have traversed extraordinary experiences in the form of receiving, donating, or standing closely by loved ones as they received or posthumously donated human organs."

Innovative Approaches in Regenerative Medicine:

As the field of regenerative medicine progresses, researchers are exploring novel technologies and strategies to advance tissue regeneration and functional recovery. Among these innovations is 3D bioprinting, a technique that allows precise placement of cells, biomaterials, and bioactive substances to construct intricate, hierarchical structures resembling natural tissues and organs. Through the utilization of 3D bioprinting, scientists can produce personalized tissue constructs with meticulous spatial organization and vascularization, addressing the limitations of conventional tissue engineering methods. This innovation holds significant promise across various applications, including organ transplantation, tissue replacement, drug screening, and disease modeling. Additionally, breakthroughs in organoid culture and organ-on-a-chip systems are transforming our ability to replicate human physiology and disease in laboratory settings, offering novel platforms for drug discovery, toxicity testing, and personalized medicine. These miniature organ models faithfully mimic the structure and function of native tissues and organs, providing valuable insights into disease mechanisms and facilitating the development of targeted therapies.

Challenges and Considerations:

Despite the impressive advancements in regenerative medicine, numerous challenges and considerations must be addressed to fully realize its clinical potential. Standardizing protocols for cell production, quality assurance, and scaling up manufacturing to meet clinical demands remains a significant hurdle. Furthermore, navigating regulatory and ethical issues related to the use of stem cells and tissue-engineered products in clinical settings is crucial to ensuring patient safety and upholding ethical standards. Long-term safety and efficacy studies are also imperative to evaluate the sustainability of regenerative therapies over time.

Role of Comprehensive Health Assessments in Regenerative Medicine:

Comprehensive health assessments play a pivotal role in the realm of regenerative medicine, serving as a foundation for patient evaluation, treatment planning, and monitoring of therapeutic outcomes. These assessments encompass a holistic evaluation of an individual's health, including medical history, physical exams, diagnostic tests, imaging studies, and biomarker analyses. By conducting thorough assessments of organ function, tissue integrity, and overall physiological well-being, healthcare providers can identify underlying health conditions, risk factors, and potential contraindications for regenerative therapies. This allows for the customization of treatment plans to meet the specific needs of each patient, optimizing therapeutic outcomes and minimizing risks. Furthermore, regular monitoring of patients undergoing regenerative therapies through comprehensive health assessments enables healthcare providers to evaluate treatment efficacy, safety, and long-term durability. By tracking changes in clinical parameters, biomarkers, and imaging results, healthcare providers can assess treatment response, detect adverse effects or complications, and modify treatment strategies as necessary to enhance patient outcomes.

There are many good hospitals in India that offer health checkup packages for undergoing a regular full body health checkup that play an important role in regenerative medicine.

Yonas had all but given up hope of reaching European shores when he was approached by a Sudanese man, who gave his name as Ali, at a street market in Cairo. Yonas told him his story. Ali said that he knew a way that Yonas could pay back all his debts and secure a place on a more reliable fishing vessel crossing from Egypt to Italy. He told Yonas he could sell his kidney, make a lot of money and save a life in the process.

Yonas had his doubts. But he had amassed significant debts trying to cross the Mediterranean and he was coming under pressure to pay back friends, family and moneylenders. “This is the last thing you want to do,” he explained. “But for me there was no other way.” Ali, the broker, was personable and seemed genuine. Yonas agreed to the deal. He was promised $10,000 for his kidney. The money, he hoped, would be enough to cover his debts and pay for his onward journey across the Mediterranean.

The surgery took place at a medical facility near Alexandria in November 2018. “I remember waking up and feeling confused,” said Yonas. The first thing Yonas he was aware of was a buzzing noise coming from a loose lightbulb, like the sound of a trapped insect. Next came pain, then fear, panic, anger. “I was shouting as loud as I could. I just wanted to get out of there.” Yonas rolled over and vomited on to the floor.

Hours passed. Finally the door opened and a man holding a clipboard came in. The man told that Ali would be coming soon, at which point he could leave. He handed Yonas two painkillers and a glass of water, and slid out the door before Yonas could ask any questions.

When Ali finally appeared, he told Yonas to get dressed. His voice was hard, all his old charm now gone. A nurse removed the drip attached to Yonas’s hand and two heavy-set men escorted him back to the car. Yonas spent the next two weeks in an apartment in Cairo convalescing. He was closely monitored, in case he should decide to leave the apartment. They did not want him to attract attention. If someone were to see him, they might report his presence to the police. Best to keep him hidden while he healed.

Yonas had been promised $10,000, but he was given just $6,000 in notes. This would just about pay off his existing debts, but it was not enough to cover the cost of smugglers’ fees ($3,500) for the next stage of his journey, across the Mediterranean. Yonas went to the police and reported Ali for trafficking. He was trying to explain that he had been deceived into selling a kidney when another officer entered the room. The second officer informed Yonas that it was a criminal offence to sell a kidney. He took out a notebook and asked Yonas for his identification papers. Yonas fumbled in his pockets, searching for documents he knew he didn’t have.

The officers joked that Yonas didn’t look like an Egyptian, remarking on his dark skin and curly hair. If he was a refugee, they suggested, he should go and complain to the UNHCR. But maybe he wasn’t a refugee. Maybe he was an illegal migrant. The second officer reminded Yonas he could be arrested or deported for failing to produce his identification papers.

Yonas was regretting going to the police. He looked around, nervously waiting for someone to speak. The second officer smiled scornfully and told him to leave.
