First Successful Cell Transplant Cures Diabetes 271

Posted by timothy from the place-your-nobel-prize-bets dept.
Iphtashu Fitz writes "A few months ago the 50th anniversary of the first organ transplant was celebrated. Over those 50 years surgeons have learned how to sucessfully transplant many organs and other body parts. Now it seems that Japanese surgeons have added yet another successful transplant to the list, having recently transplanted insulin-generating cells, known as Islets of Langerhans from a mother to her diabetic daughter. Three months after the surgery both mother and daughter appear to be completely healthy. Although the daughter no longer needs insulin she still needs to take powerful drugs to keep her immune system from rejecting the new cells. Researchers also still don't know if this procedure would work in many people with type 1 diabetes since in many of those cases their own immune system has destroyed their Islet cells."

    With the advent of this new treatment, maybe thousands of diabetics could have the ability to live insulin-injection free. Yes, they do have to take anti-rejection drugs, but it is no different then taking the drugs for an organ transplant. Even if this is only a prelude to a new, more permenent treatment, the possibilities of this doing good with this new treatment is huge.

      This isn't new, unfortunately. Islet cell transplants have been happening for many years now. The first cases I heard of were in Russia, using islet cells from aborted foetuses (I gather such things are more readily available in Russia). But they've been doing it on a small scale in the UK for years, too, with success.

      I'm not sure why we haven't seen this become a mainstream solution yet, but personally, I'm not holding my breath for any of the diabetes solutions that get mentioned by news reporters regularly. News services seem to like to this story so much that they declare a new "cure" each year... except that it'll be years before most people get it, if they get it.

          Diabetics learn very quickly how much insulin they require and to adjust it as they see fit.

          On the insulin side, we have a wide range of available, from very rapid acting ( taking effect within 10 minutes to provide "bolus" (peak) insulin for when you eat) to very long acting (lasting up to 24 hours to provide "basal" (background) insulin). Using different insulins diabetics can get a remarkably precise control with little effort.

          As for hypoglycemia (low blood sugar) leading to diabetic coma, this is easily avoided by any diabetic with even "rough" control due to the fact that they will readily feel blood sugar levels dropping far in advance of danger and a quick ingestion of some sweet substance will solve the problem in a matter of a couple of minutes - actually, it's quite remarkable how quickly the sugar is absorbed and works it's magic.

          It's not hard these days to keep your diabetes in fair control, and within or close to the "normal" range that will keep problems later in life at bay. Diabetes is in essence a very treatable and predicatble ailment once detected.

          Detecting it in the first place is probably the biggest problem these days - so many people don't recognize the symptoms...

          a) Excessive thirst and urination - this is the biggie, classic and very telling symptom. Your body is working hard trying to flush itself, but it can't keep up.
          b) Tiredness - the higher your BG gets, the more tired you get
          c) Weight loss, dehydration.
          d) Sweet fruity smell on the breath - your body is having to break down fats to get at sugars and as a result it's producing some pretty nasty by products - your getting keto acidosis. At this point you are extremely ill and must get to a doctor very quickly. I mean VERY quickly... if you delay then you may fall into a coma, your brain will swell, and rather soon, you will die.

          People often leave it much to late, not getting diagnosed until they are in a state of acidosis - I know, I did - almost too late, but once diagnosed, a couple of days in a hospital and some home visits by a diabetes nurse educator I was fine - 10 years later I'm still fine, and I expect to still be fine for another 40 to 50 years at least.

          • I'm not diabetic, but I do get hypoglycemic (low blood glucose) quite easily. Sugar does act very quickly in those circumstances, but then the danger becomes dehydration (which, BTW, can cause hypoglycemia ... see the pattern?).
          • He lived alone, got sick and was bedridden. Because of this his blood-sugar levels went haywire, and he died from diabetes. Yes, he know all about the levels of insulin etc he needed to take, but sometimes circumstance renders you unable to take it.

            As for the rejection medicine... I'd assume that if you missed that then you would more likely reject the organ, and then be back to square 1. But square 1 is better than dead.

          • I agree with you that diabetics learn very quickly how much insulin they need.

            Really, sometimes they can feel their blood sugar level without need to test it. But in some cases, they can suffer extreme blood sugar levels because of stress, anxiety or nervousness generated by problems or the like. In these cases is when diabetes could be a very dangerous illness.

        I assume diabetics just need to take shots.

        (talking purely about type I diabetes [wikipedia.org] here)

        Yeah, you're exactly correct except for the "just" word ;-). Speaking as a type I diabetic, with a type I brother and a type II stepfather and a type II stepbrother - keeping control of the blood sugar levels can be a bitch. Regardless of whether you're injecting insulin or not.

        I wouldn't consider a "treatment" involving immunosuppressant drugs unless my blood sugar levels were really severely out of control (and I'd tried a variety of alternatives). Anti-rejection drugs suck.

        I was much more excited about the Glucowatch [glucowatch.com] product (nice asynchronous, albeit approximate, blood sugar monitoring tool), but I first heard about it a couple of years ago and still haven't seen any sign of them being available in Australia. Motherfuckers.

        In fact, the Glucowatch website doesn't seem to have been updated in about a year. Hmmm. I wonder what's happening with them. I hope they get their shit together at some time, as the Glucowatch could be a really really useful tool.

        • From previous posts at alt.support.diabetes.uk, I gather that the readings the watch gave were a bit hit and miss according to skin contact and sweat levels, plus you still had to take a regular blood sample to calibrate it. There's been talk recently of a new BG monitoring technique involving infra-red light (I think). The group's worth a lurk.

          I'm not diabetic, but have a type 1 child.

          At first we were really excited about the GlucoWatch until we looked more deeply into it. It was pretty disappointing. Supplies for it are very expensive. By contrast, insulin pump therapy supplies are inexpensive. (All of the various brands of pumps we looked at ranged between $5,500 and $6,000.) I was also not real impressed by the accuracy of the GlucoWatch.

          Pump therapy is good and getting better. Our hospital has told us that within the year that the MiniMed [minimed.com] pump (Medtronics) will have an upgrade that can monitor BG levels and alert you if they are falling (or rising). They are supposed to already be in clinical trials.

          The pump trainer (employed by the hospital) also said that in a generation or so of pump, they expect to have a closed loop system where the pump will adjust your insulin dose without user interaction for rising BG, and alert you for falling BG.

          Even the current generation pumps (which we have in hand, but have not yet installed batteries nor had the 24 hour hospital stay to begin using) have a radio link between the glucometer and the pump. If you are taking BG readings frequently enough, the pump always knows your BG levels and can automatically suggest a bolus.

          We were very impressed by the sophistication of the current pumps. The fact that MiniMed often has a $200 yearly upgrade was a major selling point for their particular brand.

          Pumps are supposedly bullet proof (and water proof), but I wouldn't want to test this.

        The idea that a diabetic just takes shots is not true at all. My brother has type 1, he was initially misdiagnosed and he almost died. The shots are intended to counteract the sugar in the food you eat. Now if you should mess up somehow, and it does happen, you could be in trouble. Low blood sugar, possibly caused by too much insulin, can cause a sudden diabetic coma and a trip to the hospital. Additionally, your blood sugar is affected by your mood and sometimes by nothing at all. I've heard that teenage guys can suddenly have their blood sugar go nuts when a pretty girl walks by. Some diabetics can tell when their blood sugar feels off and begin treating themselves, but some cannot. Also, when a diabetic has very high or low blood sugar, it affects their brain and their ability to think clearly. In school, all his teachers knew that if he should feel funny, they had to send another student to escort him to the nurse; otherwise he could literally get lost along the way.

        In any case, many diabetics do not monitor themselves properly. They allow their blood sugar to consistently run too high, which in the long term can cause kidney failure, foot amputation, blindness and a host of other problems. Even diabetics that do monitor their blood sugar properly risk these things.

        My brother has had a much easier time since he switched from injections to an insulin pump. He still has to do the tests, but when you're out in public, a finger prick test can be done fairly privatly, while injected yourself in the stomach cannot. With the pump, he hits some buttons on it and he's done.

        I'm not sure that the rejection pills would be better, since I don't really know much about them. But I do know that diabetes is not at all the "I just take a shot" most people think it is.

Because your body cannot regulate your blood sugar you have to do it yourself with both diet and medication, all day, every day. The consequences of failure can be fatal. Even if you do a good job, diabetes will almost certainly reduce your lifespan by more than 10 years. The consequences of failure also include blindness, kidney failure, the loss of limbs and heart disease. Yes, it is a trade I would make.

        The cocktail of immuno-suppressive drugs (in some form or another) is something you pretty much take for life after an organ transplant.

        I am a physician, and I've never heard of people being completely weaned from drugs. If they were, they would run the risk of their immune system reasserting itself big and ugly, possibly resulting in an episode of acute rejection (which is no joke). I can see them trying to taper the dose down a bit, but immunosuppressive therapy remains the standard of care.

        If this is something new, I'd love to see it happen, because those drugs are very problematic for patients. They not only leave you susceptible to common infections, but they also increase your risk for cancers.

        Never underestimate how many potential cancers your immune system finds and kills early. You should see some of the post-transplant patients who have spent time in the sun... they grow skin cancers like it's their job.

      A friend of mine is the recipient of a transplanted kidney and pancreas (I think he's one of the first to get that combination). It cured his diabetes and kidney failure, but he obviously has to take the usual recipient's cocktail of drugs, and it's no picnic.

      The immunosupressants means that he has to go to the hospital any time he gets a bad cold, infections are a constant problem and fear, and the prednisone (anti-inflammatory steroid that all recipients have to take alongside the immunosupressants for the rest of their lives) causes bloat, loss of muscle mass, sleeplessness, and the "shakes". That's just part of the story.

      In his case the choice was clear: dialysis sucks bigtime. But if it was me and the choice was insulin vs. the drugs transplant recipients have to take, I'd stick with the insulin, no contest.

      It all comes down to a personal decision, but her choice is not the one I would have made; I wonder if she really knew what she was in for? I certainly wish her luck. At least in her case rejection probably just means that she'll have to go back to the insulin.

    Is the pancreas like the liver, that if you take part out of a living human, transplant it in another person, both livers will grow back to their normal size. Will that happen with a pancreas, or is the mother stuck with 50% of her pancreas.

    Nor is it clear whether the procedure would be as effective in people, like most of those with type 1 diabetes, whose own immune cells have destroyed their insulin-producing pancreatic cells.

    How does this happen? Is this a problem with the immune system, or is it a problem with the pancreas?

    If the immune system is responsible for the damage to the pancreas, then transplants won't work. We need to find out the cause.

    If the problem is with the pancreas, I think a far more effective treatment will be genetic therapy. Since genes control how much of a protien or enzyme is made, if the gene is damaged due to mutation or any reason, that tissue might not function normally. If we can advance gene therapy, we can replace the malfunctioning DNA with working DNA.

    A friend of my mothers about 3 years ago had this same type of surgery done. She had type-II diabetes since she was a teenager and had required shots. She no longer has to take insulin shots twice daily which has now been replaced by the pill.

    I saw someone post something about whether this would actually change quality of life, and I can say from seeing those close to me, yes. My father died of pancratic cancer, and the cancer caused type-II diabeties, and the ammount of effort that had to be put into regulating insulin levels, taking your shots, checking your blood, it all adds up. To just take a pill in the morning instead is considerably easier.

    Personally, I wouldn't like having to check my blood 3 times a day, and give myself injections on top of that. I'm sure most other people wouldn't like that either, to have that replaced by a pill would be a god send.

  • As far as I know (being type I), immunosuppressant drugs are considered worse than insulin in general. IF your diabetes is well regulated, your health can be perfect. Immunosuppressants on the other hand seem to cause some risks.

    The situation is different if the diabetes is not well regulated, for instance if the kidneys have been destroyed. In the latter case, when a kidney transplant necessitates immunosuppressants anyway, I believe it is quite common to also implant an extra pancreas (hopefully from a d

    "Scientists have made many advances in islet transplantation in recent years. Since reporting their findings in the June 2000 issue of the New England Journal of Medicine, researchers at the University of Alberta in Edmonton, Canada, have continued to use a procedure called the Edmonton protocol to transplant pancreatic islets into people with type 1 diabetes. A multicenter clinical trial of the Edmonton protocol for islet transplantation is currently under way, and results will be announced in several years. According to the Immune Tolerance Network (ITN), as of June 2003, about 50 percent of the patients have remained insulin-free up to 1 year after receiving a transplant. A clinical trial of the Edmonton protocol is also being conducted by the ITN, funded by the National Institutes of Health and the Juvenile Diabetes Research Foundation International."

As a result her immune system was not attacking her beta cells so this case is rather different from that in most type 1s whose bodies would attack implanted cells normally.

    The short answer is No. Immuno-suppressents are not as bad as they sound. Taking them is no big deal.

    I've been on them for 4 years, since my kidney transplant. Contrary to popular belief they do not make you much more susceptible to every cold and flu going around. Obviously you are slightly more vulnerable to viral infections.. but in the last 4 years I have not suffered from any more illnesses than anyone else I know.

        Alright, I'll be honest, its more than one pill.
        I take one immuno-suppressent (Cyclosporin) twice a day and one (very small dosage) steroid a day and my blood pressure pills.

        But my point is I was on maybe 4 times as many pills before my transplant. And the longer you are on dialysis the weaker your bones, heart and other parts become. Also dialysis is time consuming and very depressing.

        You can lead a normal life on immuno-suppressents. I and countless others do. I would not have a normal life without my transplant, if indeed I would still be alive.

        People should not be knocking transplants simply because they require you to take the immuno-suppressents afterwards.

    My father has diebetes, and though immuno-depressing drugs do not sound so great, having his insulin level constantly in sync with his blood-sugar level should greatly help prevent diebetic complications (which are far worse than the daily dealings with the disease).

    My father's daily routine is

    1) measure his blood-sugar level (pricking the finger is the most accurate way to test)

    2) injecting himself with the appropriate insulin amount.

    However, there is a limit to how many times a day this can be done which results in stress to his system inbetween injections.

    Though he is a type I diebetic, I certainly would not mind giving this treatment a shot even if his immune system would sabotage things in the end. I happen to live in Japan so it is not like I can complain about the treatment being too far from home . . .
