A good day for medical ethicists

Great news! Sort of. I watched this trickle through the scientific press for a while and I guess I can no longer ignore it.

Researchers in the US are closing in on a therapy that could reverse harmful ageing processes in the brain, muscles, heart and other organs.

[…]The infusions had a striking impact on the animals’ performance. Aged rodents … found their way around a water maze as well as six-month-old mice, and reacted like three-month-olds in an experiment that tested how well they remembered a threatening environment.

[…] Chemicals … encouraged the growth of blood vessels in the aged brain, which improved circulation in the organ. They also boosted the numbers of neural stem cells, which mature into brain cells. Older mice that received [it] had a sharpened sense of smell, able to distinguish odours as well as young animals could.

To reverse aging even a little bit sounds like a miracle. And not a congratulations-now-you-have-cancer miracle like telomerase but the sort of thing an actual person could use. You might ask why I feel a little trepidation about this news hitting it big.

Hopes have been raised by three separate reports released by major journals on Sunday that demonstrate in experiments on mice the dramatic rejuvenating effects of chemicals found naturally in young blood.

Infusions of young blood reversed age-related declines in memory and learning, brain function, muscle strength and stamina, researchers found. In two of the reports, scientists identified a single chemical in blood that appears to reverse some of the damage caused by ageing.

So we can (maybe, pending clinical trials) revitalize the elderly. It might even be easy. The caveat is pretty big though. We already know that young blood does the trick (in mice), so unless the purified protein (GDF11) works nearly as well and does not cost much you will soon see a demand for blood from lots and lots of children.

That may sound like a stretch. I hope so, but think about the potential market demand. It would make viagra look like a niche product. Literally every living person will want it. Can they make enough synthetic GDF11 to satisfy all that demand? Can they make it cheap enough for everyone to afford? Anyone with a pamphlet’s worth of medical knowledge and a centrifuge can make blood plasma. Much as we collectively do not want to see a black market show up, a lot of us individually will have a hard time not willing one into existence.

    A poem by William Empson, just because of the third stanza.

    Missing Dates

    Slowly the poison the whole blood stream fills.
    It is not the effort nor the failure tires.
    The waste remains, the waste remains and kills.

    It is not your system or clear sight that mills
    Down small to the consequence a life requires;
    Slowly the poison the whole blood stream fills.

    They bled an old dog dry yet the exchange rills
    Of young dog blood gave but a month’s desires.
    The waste remains, the waste remains and kills.

    It is the Chinese tombs and the slag hills
    Usurp the soil, and not the soil retires.
    Slowly the poison the whole blood stream fills.

    Not to have fire is to be a skin that shrills.
    The complete fire is death. From partial fires
    The waste remains, the waste remains and kills.

    It is the poems you have lost, the ills
    From missing dates, at which the heart expires.
    Slowly the poison the whole blood stream fills.
    The waste remains, the waste remains and kills.

    I don’t know if that’s true. Plasma has a lot of problems, like the need to screen for infectious diseases and competition from other legitimate uses, and plasma specifically from young people is going to be harder to get. If you can get away with small doses- and GDF11 will probably be something needed in quite small doses- it will probably be cheaper to synthesize it than to use plasma.

    @Tim F.: no IRB in the world, or at least in the US, would allow investigators to draw enough plasma to do the research that might be done, for example, on plasma from adult donors. So I believe the bulk of the research will eventually be done in the lab through recombination technology, and researchers will pay the cost. Same has been true for many cytokines, etc, that were originally identified in human plasma.

    @Roger Moore: True, small proteins (usually) do not cost much to make. That does not mean it will be cheap. Remember that whatever drug company will charge through the nose during the patent years to recoup r&d costs. Retail price will have almost literally nothing to do with manufacturing cost.

    Meanwhile with plasma you only find expensive quality control like virus screening on the regulated “white” market. I expect that enough people will want so badly that the other kind of market will pop up to meet demand.

    There was another series of science fiction stories by James Gunn (probably arising from the original 1950s blood research) of a young man whose blood gave one renewed youth – so long as you got a transfusion regularly. It was novelized as The Immortals

  46. 46
    Tim F. says:

    @Thomas: Once again, I am not too interested in how the legitimate market approves the eventual drug. People with access to the original research, aka everyone, will understand that plasma works at least as well as the purified protein. Odds are that the full benefit comes from more than one blood protein and simultaneous trials of two new drugs for one therapy is unheard of (I had this actual conversation with Pharma researchers during a job talk). People know perfectly well that a young blood transfusion at least does no harm so the usual concerns about untested therapies will hardly keep anyone away.

    Fair Economist says:

    This isn’t so revolutionary. Actually, I’m extremely skeptical. There have been reports before of blood transfusions from young mice making old mice somewhat healthier. Far more importantly, though, these are inbred mice. There have been a kazillion treatments that extend life in certain inbred lines that don’t help or even hurt with people. The megavitamin therapies that were so hot around 1990 are probably the best-known example. Basically, inbred mice are hopelessly messed up – they are made with dozens of generations of brother-sister matings, which have a similar effect on them as they do on us. It’s often possible to make these profoundly sick mice live longer with various treatments, but they turn out to be just correcting or compensating for the inbred defects. In outbred mice, and in humans, the treatments are useless or even harmful.

    Speaking of Sci-Fi, there was a season-long story in Torchwood called “Miracle Day,” in which suddenly it became impossible for humans to die. There were scenarios sketched out on how horrific this would quickly become, as the burgeoning population went through all the food stocks, and then proceeded to exist on the denuded Earth in eternal starvation (as it would be impossible to starve to death). In the story, they eventually resorted to cremating live people as this was the only method to get them out of the way.

    @Tim F.:

    Imagine how happy it will make the Red Cross to lose all that blood to people who have no urgent need for it.

    The Red Cross might finally have to let go of their outdated ban against taking blood from people with hereditary hemochromatosis. It’s the weirdest thing- they won’t take it because it violates their rule against compensation for blood donation- since HH patients would otherwise have to pay for their phlebotomies, the Red Cross counts that as compensation. So, instead, health insurance pays for blood draws and then the blood gets thrown away, even though it’s just as safe as healthy non-HH blood for transfusions (other than being higher in iron, which is often actually a plus for people getting blood). It’s ridiculous. I’ve read that HH is so common that permitting HH blood to be taken at blood donation sites everywhere could end the blood shortage issue. And since most HH people aren’t diagnosed until health problems show up later in life, it wouldn’t compete with this apparently soon-to-be-expected demand for young blood.

    New York’s Blood Centers are perfectly happy to take that iron-laden blood, as are centers in a few other states. But the Red Cross controls almost half of the nations’ blood supply, and it just seems dumb not to encourage a symbiotic relationship between people who need to have their blood drawn and places that distribute it.
