Immune Modulating Treatments for Type 1 Diabetes
If you need an organ transplant and you have an identical twin willing to donate, you have an excellent chance for success in most cases. Unfortunately, there are exceptions. Patients with type 1 diabetes are unable to produce insulin because of autoimmune damage to the pancreas. The medical literature reports that partial pancreas transplants have been performed between identical twins, with healthy donor and diabetic recipient. This should have cured the diabetes. But it did not cure the autoimmune process that destroyed the recipient twin's original pancreas. The transplanted partial pancreas was also destroyed in a short time.
Type 1 diabetes patients are at risk of damage to many organs and tissues from blood sugar levels outside the normal range. When kidney failure occurs, a treatment option is a combined kidney/pancreas transplantation. Immunosuppressive drugs are necessary for the kidney transplant in almost all cases (since most people don't have identical twins). When the donor kidney comes from a cadaver, it seems reasonable to give the recipient a new pancreas as well. A recent article in the Diabetes medical journal reports on three such patients. All received thymoglobulin and daclizumab as immunosuppressive drugs. Two also received rituximab. These drugs were sufficient to save the new kidneys from immune attack, but the new pancreases were also damaged, and type 1 diabetes returned.
Mycophenolate mofetil has been tried on patients newly diagnosed with type 1 diabetes in another attempt to stop the autoimmune process. Unfortunately, it was not effective, either alone or in combination with daclizumab.
These failed attempts to stop disease progression with standard immunosuppressive drugs are undoubtedly frustrating to researchers and patients alike. However, they do provide important data. The immune system is perhaps the most complicated system in our bodies, and knowing what does not work gives us clues about where to look next.
Research approaches using blood-derived stem cells have demonstrated promising results in animal models. Check with your doctor to see what the latest results mean to you.

Kidney-Pancreas recipient says 'save a life - carry a donor card'

Geraldine Grant's life was transformed by a kidney-pancreas transplant

Geraldine Grant is one of only a handful of diabetes patients of her type in the world to undergo a kidney and pancreas transplant.
Now she wants Oxford Mail readers to do something world-changing too, by becoming organ donors.
Fifty-one-year-old divorcee Mrs Grant, from Kennington, was diagnosed with diabetes when she was 24 — and for more than 20 years was treated with insulin as a Type 1 diabetic.
In 2002, as is common with many diabetics, her kidneys started to fail.
Two years later, she was forced to have a kidney removed.
And it was then that she made a startling discovery.
She said: "After they removed one of my kidneys I found my blood sugar levels stayed okay and I didn't actually seem to need my insulin injections. I was very puzzled.
"I stopped taking the injections and went back to the Churchill Hospital for tests and they found I wasn't a Type 1 diabetic after all, I actually had Maturity Onset Diabetes of the Young (Mody).
"This is more difficult to diagnose than other forms of diabetes and basically meant I had inherited diabetes, I hadn't developed it, and my body had actually been producing insulin all along. “Despite having taken insulin for more than 20 years, I may not have needed it at all."
Mrs Grant spent the next two years controlling her diabetes with a strict diet and daily blood monitoring, but doctors told her she would one day need a transplant.
She said: "In 2006, the Churchill's transplant centre put me on the waiting list for a kidney transplant, but my doctor put the case that I needed a new pancreas too.
"This was very unusual as only Type 1 diabetics — whose bodies cannot produce insulin — usually qualify for a new pancreas. But it went for a review and I was put forward for the double transplant."
In 2007, suffering a lot of pain, anaemia and with soaring blood pressure, Mrs Grant was forced to go on dialysis for 18 months until a donor could be found.
She said: "When the transplant call eventually came it was a case of 14th time lucky.
"After the operation my doctor came to see me and told me just how unusual it was for a Mody patient like me to have a pancreas transplant. I have been so lucky."
But Mrs Grant's joy has also been tinged with concern for her four children.
She said: "When they discovered I had inherited diabetes, my four sons were tested straight away and two, the eldest and the youngest were both found to have the Mody gene. I was very upset.
"The oldest, Alex, 27, is now taking tablets for the condition, Fraser, 19, the youngest hasn't shown any signs of the disease, but it has made me worry a lot about what will happen to their health in the future.
"My new kidney has taken wonderfully and although I've had some little problems with my pancreas, I do feel a lot better in myself.
"All my sons are now organ donors and I'm very proud of them for that.
"But I would like to see everyone become a donor who can — you don't need those organs after you have gone and they can help so many other people..”
