The First Pig-to-Human Organ Transplants Could Happen This Year (medium.com) 88

Every day in the United States, 17 people die waiting for a lifesaving organ transplant. To address this crisis, one biotech company is turning to an unlikely source: pigs. Maryland-based United Therapeutics says it plans to begin transplanting organs from genetically modified pigs into people as soon as this year. From a report: "We're right on that cusp. We're looking to get into humans within the next year or two," said David Ayares, PhD, in an exclusive interview with Future Human. Ayares is the chief scientific officer of Revivicor, a subsidiary of United Therapeutics that's developing the pigs. "We think we have the pig that is going to be what we bring forward into humans in 2021 or 2022." For decades, scientists have been hopeful that organs from other species could be used to replace faulty ones in humans, known as xenotransplantation. But animal organs trigger immediate and severe immune reactions when transplanted into humans.

    This would be very useful. Pigs are roughly the size of humans, so it's a good match. Better than waiting for some poor idiot to get in an auto wreck and beg for their leftover organs.

      When you transplant an organ into someone, you give them some drugs to prevent rejection. Those drugs cripple parts of the immune system.

      Transplanting an organ that you know is full of COVID-19 is not a good idea.

        • But don't most transplants come from people who are not sick? That is why I thought auto accidents were a major source. Seems unlikely you would transplant an organ which definitely has covid virus in it to a recipient. You just gave them covid and the immune suppressing drugs used in transplants means the recipients immune system will not be fighting the virus.

          No. Too many people on the list die - about 6-7% annually. (Make sure you're an organ donor!) But in any given year your odds of getting a transplant are still much greater (6-7x) than dying.

          As for bad organs, there's a lot of issues. One is you won't get another if they transplant a COVID organ. The anti-immune system drugs might make a bad donor organ worse than your current one. Doctors are hesitant to do it for liability reas

          The waiting list is long for several reasons. For example, you can't transplant a child's heart into an adult and vice versa. Too much difference in size.

          You have to take into consideration blood type. If your blood type and the proposed donor's blood type don't match, no transplant.

      COVID-19 and Multiorgan Response [nih.gov]

      Abstract: Since the outbreak and rapid spread of COVID-19 starting late December 2019, it has been apparent that disease prognosis has largely been influenced by multiorgan involvement. Comorbidities such as cardiovascular diseases have been the most common risk factors for severity and mortality. The hyperinflammatory response of the body, coupled with the plausible direct effects of severe acute respiratory syndrome on body-wide organs via angiotensin-converting enzyme 2, has been associated with complications of the disease. Acute respiratory distress syndrome, heart failure, renal failure, liver damage, shock, and multiorgan failure have precipitated death. Acknowledging the comorbidities and potential organ injuries throughout the course of COVID-19 is therefore crucial in the clinical management of patients. This paper aims to add onto the ever-emerging landscape of medical knowledge on COVID-19, encapsulating its multiorgan impact.

      Unfortunately, COVID has also led to substantial reductions in hospital capacity: so many ICU bed and staff are devoted to COVID, there is less available capacity for...well...everything else we normally use the health care system for.

      • The ICU isn't a surgical theater. Moreover, hospitals where transplants are performed have dedicated areas for transplant patients, mainly because they're especially vulnerable to all of the other crap that other patients bring in. The last thing they would do is start mixing them with covid-19 patients.

        • by sjames ( 1099 )

          However, once you're out of surgery, you will need one of those ICU beds for a while. You'll also need ICU nurses who are currently busy dealing with the ICU crammed to capacity with COVID patients.

          • You will need nursing care, yes. But my hospital uses separate staff, even in the ER, for COVID patients. The rooms might bear physical proximity, but the staff don't mingle.
            • by sjames ( 1099 )

              Yes, they keep the staff separate, but they still have to allocate that staff. That would be the staff devoted to COVID and not to everything else.

      - As has already been mentioned, immunosuppressive drugs will make the recipient more susceptible to mortality from covid-19. Although I would probably be fine if I caught the virus, the same can't be said for a new organ recipient. During the surgery, and for several months afterwards, they put you on an extremely high dose of immunosuppressive drugs, so your immune system is pretty well trashed until they begin titr

      The only things which are made unlawful for you are the flesh of dead animals, blood, pork and that which is not consecrated with the Name of God. But in an emergency, without the intention of transgression and rebellion, (it is not an offense for one to consume such things). God is certainly All-forgiving and All-merciful.[8]â

    > In one famous case in 1984, a newborn in California known as “Baby Fae” received a heart from a baboon but died less than a month later when her body rejected the organ.

    My parents were pitched by this exact "team" of researchers, to use a baboon valve in my infant aortic valve surgery. My parents and I have long ago forgotten their names. They killed lots of people, not just Baby Fae (which was a full heart transplant) and you can note that their names are omitted from the Baby Fae wikipedia entry. I got a synthetic valve (4 decades and 2 more valves later, I'm still here), but notably the girl who was in the surgery theater next to mine was getting the exact same synthetic and died on the table.

    Pig materials (similar to cadaverous materials) have a pretty short viability, once implanted. 2 years, is not uncommon, as they tend to fail slowly (and obviously). The blood thinner required for a synthetic has almost never been an impact to my lifestyle (semi-monthly blood tests, a little extra bleeding from cuts/bruises). Major injuries (even broken bones) would be problematic, but I've managed to avoid that. The ticking is an AMAZING tool to self-measure your heartrate or allow your family/partner to measure it without contact (like tachycardia, working out, etc). Animals like it too.

    It's surprising how the literature has changed [acc.org] over the years. Now organics are all the rage and I would *NEVER* get an organic replacement valve. For some full organs sure, but I would still take a synthetic heart. Seeing animal organs on the horizon, should give some indication of how far away growing organs, has to go.

      To be fair, the technology has progressed a LOT in the last decade. Before we were just patching tissue with tissue and hoping to avoid rejection but now we're actually modifying the genetics of the source animal so that they will be [more] compatible with it's new human host.

  • The real benefit is when patients can have their DNA sampled and used to produce the organs. Then it would be possible to have a replacement without any of the rejection or other compatibility issues. Being able to copy and grow most or all parts of a human body would have revolutionary potential.
