Summary
New onset diabetes after transplantation (NODAT) is a frequent and feared complication after kidney transplantation and leads to an increase in cardiovascular complications as well as in the rate of graft loss. Very little data exist on how patients in which NODAT has been diagnosed should be treated. It is suspected that Cylosporine A (Sandimmun, TM) is less diabetogenic than Tacrolimus (Prograf, TM). Furthermore, it has been described that early initiation of insulin treatment in Diabetes mellitus type 2 can preserve and improve the function of the insulin secreting cells in the pancreas. Therefore, the investigators test the effects of conversion from Tacrolimus to Cyclosporine A in patients with newly diagnosed NODAT who have just started early treatment with insulin. The hypothesis is that patients who are treated with insulin and who are switched to Cyclosporine A have improved glucose metabolism compared to patients who are treated with insulin and who remain on Tacrolimus therapy.
