NIH Confirms Protocol To Reverse Type 1 Diabetes

Posted by CowboyNeal on Sat Nov 25, 2006 09:53 AM
from the sugar-more-than-pleased dept.
FiReaNGeL writes "In 2001, researchers at Massachusetts General Hospital demonstrated the efficacy of a protocol to reverse type 1 diabetes in diabetic mice. New data from a study performed at the National Institutes of Health provides additional confirmation of the ability to reverse type 1 diabetes and on the role of spleen cells in islet regeneration. Spleen cells appear to contribute to islet recovery more in mice who are older and with more advanced diabetes compared with younger mice with less advanced diabetes, in which regeneration of remaining islets may be the dominant mechanism."

[+] Researchers May Have Found Cause of Type 2 Diabetes 181 comments
ozmanjusri writes "Scientists at Sydney's Garvan Institute have identified an enzyme called PKCepsilon as the active agent that blocks the production of insulin in diabetics. Insulin injections and implants try to control levels but do not address the reasons why insulin production is failing. This discovery may allow pharmaceutical companies to develop a drug to block the enzyme, allowing cells in the pancreas to function normally, though the team's leader, Trevor Biden, says 'What we've identified is a target that we can now latch onto to get therapy, but the journey from target to tablet of course is a long one ... It's probably going to take another 10 years at least to get something that's effective in humans.'"

    I must be missing something ... if the technique was first described and shown in 2001, then reaffirmed in 2003, why haven't they moved forward with trying to treat humans with severe/end-stage diabetes? In fact, they don't even discuss the possibility, which makes me wonder if there is something else in play (bad side effects for example). This sounds like a MAJOR medical breakthrough, and typically breakthroughs like this are pushed into more expanded trials and even human tests faster than the researchers at MGH are moving forward.

      There is no such thing as severe/end-stage type I diabetes. Usually by the time you are diagnosed, you are at the "severe/end stage" - Your pancreatic beta cells are gone or nearly so. Insulin can prolong your life for decades, and if your bloodsugars are carefully controlled (via aggressive and careful diet, insulin dosing, and glucose monitoring), you will live just as long a life as a normal person.

      If you're talking about severe diabetes complications (Kidney damage, retina damage, etc.)- By the time those present themselves, the cumulative damage of years of abnormal bloodsugars is done and curing the underlying diabetes isn't going to help.

      Last but not least, you clearly missed the "In the 2001 and 2003 studies, Faustman and colleagues treated end-stage nonobese diabetic (NOD) mice with Freund's complete adjuvant, a substance that suppresses the activity of the immune cells that destroy islets in type 1 diabetes." line. Immunosuppressants are scary shit, and usually considered an absolute last-resort treatment when the other choice is death. Admittedly, it sounds like this MIGHT be a rather targeted immunosuppressant with fewer side effects than most, but still, it's an immunosuppressant.

      I've been a type I diabetic for over a decade and have been looking forward to a cure for years. While this article gave me a lot of hope, the mention of immunosuppressants took a lot of it away. There are already quite a few treatments for Type I diabetes that are proven to work, but generally are only given to those who are already on immunosuppressants for another reason. (For example, pancreas or pancreatic beta cell transplants are only given to patients already receiving another transplant who will be on antirejection drugs and immunosuppressants anyway.)

      That said, it sounds like there are fewer side effects than other immunosuppressants, as I have heard that there are plans for human trials starting in 2007 or 2008. Six years from the first results in mice to the first human trials is actually quite quick. There are plenty of examples of cases where botched human trials nearly killed the test cases. (Remember that incident a year or two in London where 6-8 test patients basically swelled up like balloons and found that six months later most of them had trashed immune systems and the beginnings of cancer?) People are REALLY, REALLY careful with human trials.

      It sounds like they are conducting one more large-scale study in mice before beginning human trials. They didn't have money for it before, but they received a large amount from one of Lee Iacocca's charities to fund further studies.

      Given the involvement of immunosuppressants, I hope they are extra careful with human trials. I can wait another decade if it means I won't be developing cancer or a few years after treatment.

    It is very important to note that this is a treatment for reversing Type I diabetes, not Type II.

    Type I diabetes [wikipedia.org] comes from an autoimmune reaction against the insulin-producing cells. It is more common in children, and accounts for about 10% of all insulin cases.

    Type II diabetes [wikipedia.org] tends to be caused by an insulin insensitivity - the insulin receptor in cells looses its effectiveness. The complications from Type II diabetes tend to be worse, and none of them are pleasant. There are many risk factors for Type II diabetes, some of which a person can't do anything about (i.e., genetic predisposition), but the primary risk factor is obesity and inactivity. So, for the foreseeable future, doctors will no doubt continue to caution people to be vigilant about their weight and, for those under treatment for diabetes, to still be especially vigilant about monitoring their blood sugar levels.

      Ah, but there's another consideration --

      Type 2 diabetes deteriorates if not kept well-controlled. In advanced stages, the hyperglycemia oxidizes proteins and kills off pancreatic islets, until the pancreas is unable to produce insulin, just as in Type 1.

      So if an advanced type-2 diabetic fixed up their insulin resistance, they might still be unable to produce insulin. And the therapy in the article might then be helpful to them too!

        You are right on the result (pancreas no longer able to produce insulin), but your mechanism (oxidative stress) is at best only part of the picture. If oxidized proteins induced by hyperglycemia were cytotoxic, a lot more cell types in addition to pancreatic islets would be killed off.

For many, diabetes is a very manageable problem, but instances do occur with circulation problems to the limbs that require amputation. It'll be great when this cure hits the streets, and as with anything, the sooner the better, but rather than complaining that it'll take years before being available to humans, why don't we celebrate the fact that a cure is officially in sight?

She is now 9 and wearing an insulin pump, which means we change her infusion set (a fairly large needle inserted under the skin on her stomach or back) every three days. Type 1 diabetes cannot be managed by diet, exercise & pills!!!

          For young children, its burdensome, sure but everybody that has to do it gets used to it, just like anyone who has to take any kind of medicine- regardless whether its IM, IV or PO. I wasn't saying that what people go through isn't troublesome, and everyone needs shots at different intervals- everyone is different. There are exceptions to everything. Anyway, my overall point was that rather than saying, well geeze, it'll be 4-6 years before its available, waah- we should be saying Thank Someone that there's even a chance of a cure, otherwise you and your daughter are guaranteed to be doing those shots for a long time to come- now you may only have to do it a few more years- if even that. Insulin pumps have come a long way and are better than giving shots- maybe something better (transdermal patch?) will come along between now and when the 'cure' is available. I happen to know a relative who is Type 1 diabetic and has received awards for having the disease for longer than the vast majority of people (I think he's around 80 and has had it since he was young)- but he's been giving himself shots several times a day his whole life and still manages to have a pretty good existence- he used to run even up to a few years ago, still walks a lot, etc. Its a part of his life and it doesn't slow him down. On the same token, I know another friend and her husband who are in their late 50's and have nearly had to have legs amputated. There's someone on every end of the spectrum, as I said originally- but just be thankful you can look forward to the day you don't have to give those shots anymore, or she may never have to do it herself.
