Early Kidney Transplant May Benefit Some Diabetics
By David Douglas
NEW YORK (Reuters Health) - In certain patients with diabetes-related kidney disease, performing a transplant before the need for dialysis arises seems to be advantageous, researchers report.
"Preemptive transplantation remains an optimal form of kidney replacement therapy for individuals with diabetes when they receive a living donor kidney -- or when they receive a simultaneous pancreas-kidney transplant, in the case of individuals with type 1 diabetes," Dr. Bryan N. Becker told Reuters Health.
Becker, at the University of Wisconsin-Madison, and colleagues note in the Annals of Internal Medicine that reports show that the technique is effective when used before the onset of chronic dialysis. However, a number of details are lacking.
To investigate further, the researchers examined U.S. national data on more than 23,000 patients with type 1 and type 2 diabetes who received kidney transplants from living or deceased donor, or simultaneous pancreas-kidney transplantation.
In all, preemptive transplantations were received by 14.4 percent of patients with diabetes type 1 and 6.7 percent of patients with diabetes type 2.
After adjusting for factors including age, sex and race, preemptive transplantation was associated with a lower risk of dying in both type 1 and type 2 diabetics only when the transplant was from a living donor. For simultaneous pancreas-kidney recipients, benefit was seen only in those with type 1 diabetes.
The apparently reduced benefit from preemptive transplantation from deceased donors, compared to that seen in the early 1990s, deserves further study, the team concludes.
