(Ivanhoe Newswire) -- An advance in islet cell transplantation shows patients
with type 1 diabetes remained insulin independent one year after receiving islet
transplantation from one donor pancreas.
Researchers hope that islet transplantation will help type 1 diabetics to
live without daily insulin injections. Islet transplantation is an experimental
procedure where islets, or clusters of cells that produce insulin, are taken
from a donor pancreas and transferred into another person.
To increase the success rate of the transplant, doctors have recently
implanted a higher number of islets from two to four donor pancreases. However,
many factors impede the widespread implementation of the transplant, such as
negative risk factors, high costs, and the lack of availability.
To reduce these factors, researchers at the University of Minnesota in
Minneapolis conducted a study to assess the effectiveness and safety of islet
transplantation from a single pancreas. Eight women with type 1 diabetes
received islet transplants and were studied for more than two years. All eight
achieved insulin independence. Five women remained insulin independent for
longer than one year.
"Our results mark a distinct advance in islet transplant efficacy," say the
study authors. "We not only achieved insulin independence using islets from only
one donor pancreas, we also achieved superior glycemic control using
significantly fewer islets."
The authors conclude, "These findings may have implications for the ongoing
transition of islet transplantation from clinical investigation to routine
clinical care."
