“When my specialist
said ‘Marg you are no longer a diabetic, I just burst into tears. It was 36
years I was living with diabetes.”
Margaret Harrigan was the first person in South Australia to
receive an islet transplant as a treatment for her type 1 diabetes.
Now seven years on from her life-changing procedure,
Margaret is living diabetes free, a blessing both herself and her loving
husband Kerry could never have imagined. This incredible outcome was only
possible through ongoing research supported by The Hospital Research
Margaret was diagnosed with type 1 gestational diabetes when
she was in her early 20s and 30 weeks pregnant with her second child. It did
not disappear after birth.
After years of coping well with her condition, she soon
began having to inject herself with insulin five times a day before specialists
put her on a pump, which mimics the actions of a healthy pancreas by delivering
the right dose of insulin into the body.
This worked for a while until Margaret’s body began
rejecting the insulin provided through the pump and the usual signs that warned
her a hypoglaemic (hypo) episode (when a person’s blood pressure drops too low)
was approaching disappeared.
Her husband Kerry said that half the time Margaret wouldn’t
even know she had suffered a hypo the night before.
“She would often wake up in the morning and ask if she had
one! Meanwhile the night before I had woken up injected her, done all the
tests, waited until she recovered, did the tests again and then finally she
could roll over and go back to sleep. I would sit up for 30 minutes after to
make sure she was okay,” Kerry said.
At this point Margaret was at a crossroads on what to do
next when her endocrinologist, Professor David Torpy from the Royal Adelaide
Hospital (RAH), heard about the islet transplant procedure and referred her to
Renal Specialist Professor Toby Coates.
With your support of the Hospital Research Home Lottery,
Prof Coates has been able to pursue his research into islet transplantation
which involves transplanting islet cells from a donor pancreas and injecting
these into the patient as a treatment for their severe type 1 diabetes.
Margaret’s procedure cured her diabetes and stopped the heartbreaking condition
controlling her life.
Following her procedure, Margaret has returned to the job
she loves, teaching. She and Kerry have since travelled the world together. Medical research has given them the gift of
