 Well, somewhere around 20% of patients will develop diabetes following the transplant as a result of the medications. The mainstay of the medications we use is a class of drug called calcineurin inhibitors. They were developed and introduced into practice in the 80s. Those cause kidney failure. So, for instance, there's a fairly high rate of kidney failure following liver and heart transplants simply due to the drug that prevents the rejection of the organ. Hmm.
