What are islet cells?
  Islet (also called beta) cells are the cells in the pancreas that produce insulin. Typically, the destruction of these cells through some autoimmune mechanism results in type 1 (juvenile) diabetes. Type 2 (adult onset) diabetes is different. Type 2 is more involved with the body inadequately using the available insulin. This can usually be controlled with weight loss, diet, exercise, and medication.


What major issues are there in islet transplantation?
  The biggest two issues appear to be the effects of the immunosuppressive drugs and the availability of islet cells. Some very promising work on the latter is being performed at the University of Minnesota under Dr. Catherine Verfaillie at the Stem Cell Institute. There are some studies being considered with new
or different immunosuppressants as well as without immunosuppressants. This can not be considered a cure until the long-term use of immunosuppressants are no longer required.


What concurrent and complementary research is ongoing to augment islet cell transplants?
  Research includes stem cell, chimerism (freedom from immunosuppressants), islet cell isolation techniques, and other immune-suppressive drugs.

The outlook for the treatment of diabetes is much brighter than it was just a few years ago. Hopefully, it can provide some inspiration to diabetics with a renewed commitment to their health and to those who have children with diabetes.


When and where were you transplanted with islet cells and are you the first islet cell transplant patient?
 

My first islet cell transplant occurred on February 1, 2002 at Fairview-University Hospital at the University of Minnesota. I was the first person in the US transplanted as part of the expanded Edmonton protocol.
The second occurred at the same place on May 10, 2002.

I was the first US transplant in the Edmonton multicenter protocol but islet cell transplants have been occurring for quite a while. The latter are protocols that specific centers had initiated independently (e.g., the University of MN has been performing varieties of islet cell transplant protocols) to demonstrate the viability of islet cell transplant. These protocols are performed on a small number of patients. The Edmonton multicenter protocol is the first protocol to attempt to perform a study across several qualified centers to determine, among many other issues, that protocol results can be uniformly replicated in a larger group. Please investigate the Links page for more information.



How much did your insulin requirements change after the first and second transplants?
  Prior to the first transplant, I was averaging about 35 units/day (basal and bolus) of humalog through a Disetronic insulin pump. After the first transplant, the requirements were about halved to 15 units/day through the pump. After the second transplant, I removed the pump but used 2-3 units via syringe at mealtimes. This was gradually reduced as the islet cells vascularized. In July 2002, I stopped taking insulin and have not had to supplement since then. Stopping all insulin was a big mental step. In spite of the data, I had remained skeptical. I continue to test my blood sugar 6-7 times/day since the transplants.


How did you get involved with islet cell transplant centers and why did you pick the University of Minnesota?
  Through various Internet sites and news, I was aware of the study in Edmonton under Dr. James Shapiro in late 1999/early 2000. I started using the Internet to send my applications and contact any centers that performed or were considering islet cell transplants. I selected those that were within a 3-4 hour flight window from the Richmond, VA area.

The criteria for any islet cell study are very selective but I was able to meet nearly all of them. One key item was a weight limit of 70-kg (155 lbs) for the Edmonton study. After I found out about that restriction, I set about losing the 23 lbs over the next three months. In October 2001, I received a call for an evaluation at the University of Minnesota. I had also been contacted by two other centers. I researched all of the centers and was most impressed by the University of Minnesota. I was unaware of the accomplishments at the UofMN regarding pancreas and islet cell transplants prior to my research. I am very happy that I performed the diligence in performing this check because the pancreas and islet program that Dr. Sutherland and Dr. Hering have crafted is very impressive. Eventually, I had to make a decision to commit to one center. Although I am sure that all of these centers are efficiently run, there was something special about the DIIT/University of MN that appealed to me. In addition, through a unusual twist of fate, my sister, her husband, and family live in the area.

The care, concern, experience, and expertise that all of the physicians and staff at the DIIT/University of Minnesota have consistently displayed validate my decision. Based on my experience, this is the best medical care that I have ever received.

I do not wish to exclude anyone but I must name a few people who were instrumental in this treatment. First, and foremost, is Dr. Bernhard Hering - as dedicated and selfless a physician as I have ever encountered. He was always available when I needed his expertise. Right behind him are my primary clinical coordinator, Kathy Hodges, and the other clinical coordinators, Carrie Gibson and Kathy Duderstadt. They would follow my tests and condition and call whenever there were issues. They offered advice and helped ease my concerns about when I would get called for a transplant. Also, the islet procurement and isolation team. They work behind the scenes but their assistance made this possible. My lifetime gratitude to all of the above people, the nurses, staff, and everyone else for making this happen.



What was your incentive to become involved in this clinical study?
  My biggest incentive was Christopher and William, my two boys. A recent picture is on the Personal Experiences page. As is true with many diabetics, over the years I had developed hypoglycemic unawareness. With two young boys, hypoglycemia was still a concern in spite of tight management and continual blood sugar testing. They are too young to be able to assist me.

Two other concerns that encouraged me to enter were the complications associated with diabetes and whether hypoglycemic unawareness could result in some untoward event involving innocent people. This treatment would address both of those issues.

If it ends up that my data will also help facilitate this treatment for diabetics, it will be an honor to have contributed.



What medications do you take and have you had any side effects?
 

Right now I take the immunosuppressants Rapamune (Sirolimus) and Prograf (Tacrolimus). I also take Mycelex Troche, Bactrim, and Gancyclovir as preventative/support medication. These support medications will be removed over the course of the first year after transplant. In addition, I am taking some OTC vitamins/minerals: Magnesium (improves insulin sensitivity), Chromium (potentiates insulin receptors), Antoxidants, and Green Tea extract. This is a big change for me since, prior to the transplants, I did not take any medication other than insulin. Only very rarely would I take OTC vitamins, aspirin, anti-inflammatory, or cold/fever medication.

I have had periodic mouth ulcers from the immunosuppressants. That was expected and I learned to treat these when I could (thanks to my dentist, Dr. Levin, for helping out).

I had a fever in June 2002 (the cause of which has not been determined) and my white blood cell count became dangerously low. As always, Dr. Hering and the staff provided prompt treatment and advice. I went into isolation at a local hospital and received IV antibiotics and a few doses of Neupogen until my WBCs had risen sufficiently. I have been doing fine since then. Another low WBC in Dec. 02 resulted in another dose of Neupogen.

Some other periodic side effects: edema in my ankles, memory loss, rashes/itching, headaches, acne, and back pain. The appearance and intensity of these side effects appears to have a correlation to with a higher concentration of immunosuppressant levels in my blood. (See question below regarding blood tests).

These side effects have not led me to question my decision to enter this study. My quality of life has improved immeasurably since the transplants even factoring in side effects.



How often is your blood tested and how often do you have to travel to the DIIT in Minneapolis, MN?
 

I had blood tests (CBC, etc.) done 2-3 times per week for the first three months. It has been weekly since that time. Two special draws are done for Prograf (tacrolimus) and Rapamune (sirolimus) once a week with the regular blood draws to determine the levels of these immunosuppressants. The targets are 4-6 for tacrolimus and 10-12 for sirolimus. If the readings are outside these ranges, I will be contacted by DIIT to alter my daily intake of these drugs.

Up until month four after my second transplant, I was traveling biweekly to the Clinical Research Center at the DIIT/Fairview University Hospital in Minneapolis, MN. After four months, my travel to the center became monthly. For me, this study ends one year after the last transplant. I have enrolled in a long-term follow-up study. This will not require travel to Minneapolis. It will be coordinated between the DIIT staff and my local physician.



What are some suggestions to maintaining a healthy lifestyle?
  I have been fortunate in that I did not acquire secondary complications from diabetes, though some symptoms indicated to me that they were not far off.

I have been committed to frequent exercise and healthy eating for a long time and I believe it has helped delay the complications. I feel great and I am in good physical condition.

But, I have had times where I did not exercise for a while and/or ate junk. I dimly recall eating an entire bag of chips and a container of dip. Likewise, on occasion, I have frequented a burger/pizza/fried food place. However, my foray into those areas was an exception and not the rule.

Mostly, I eat a lot of vegetables, complex carbohydrates, fruits, and moderate amount of protein (meat, chicken fish, and cheese). I could become a vegetarian but I enjoy meat on occasion. This diet has worked well for me and I intend to continue using it. Other important items to consider are portion size and snacking between meals. I choose moderate for the former and I rarely do the latter.



" What opportunities have been offered to you through your involvement in this study?
 

I have been able to spread this information by presenting at JDRF functions, group functions, and through the National Kidney Foundation. I am hopeful that I will be able to participate in the World Transplant Games or the US Transplant Games.




T-shirts/Products

Will there be other apparel?
  The red image on the home page may be used next on a t-shirt. I have been working with a graphic artist, Neil Quimby on these designs and he has some other great ideas.

The design, color scheme, and fabric make for a cool looking t-shirt.


How much of the proceeds go to the fund?
  100% of the proceeds less fixed costs (web hosting, PO Box, business licensing) will go directly to the Islet Transplant Research Fund.


What is the Islet Transplant Research Fund?
  The Islet Transplant Research Fund is a fund administered under the Minnesota Medical Foundation in association with the DIIT (Diabetes Institute for Immunology and Transplantation). This fund supports the research of Dr. David Sutherland and Dr. Bernhard Hering at the DIIT. Although there is no specific web site for this fund, information about it is available on the DIIT site. All of the proceeds of this fund are used to support research costs not covered by scientific grants. These costs include equipment, research materials, lab fees, staff salaries, etc. all directed solely in support of islet cell transplant research.

The continued support of this fund is very important in continuing the significant progress of this research. Help join in making this research evolve into a commercially available treatment for diabetes. I am living proof that it can happen.


Which brand of t-shirt is used?
  I wanted to use high quality t-shirts that would be durable and decided on the Gildan 6.1 oz. UltraCotton Heavyweight t-shirt.


Who produces the t-shirts?
  Team Time Corp.


How are t-shirts shipped?
  USPS Priority Mail will be used for all orders. Please see the Products page for more details.


How should the shirts be washed and dryed?
  For best care and preservation of the screened shirts, turn the shirt inside out and wash in cold water. Hanging it up to dry or low dryer heat would add assist in maintaining the image quality. It does not matter for the embroidered shirt. The shirts are 100% cotton.
