[Combined pancreas kidney transplantation after isolated kidney transplantation].

Simultaneous pancreas kidney transplantation (SPK) is an established therapy for type 1 diabetics with end stage or preterminal renal disease. SPK is superior to isolated kidney transplantation (KTX) in diabetic patients. Even pancreas-re-transplantations are more common in these patients now, mostly after SPK. But Experience with SPK after KTX is rare. Between 1994 and 2003 six Re-SPK 4.5 to 8.5 years after KTX were performed in our department. Average age of the recipients was 40.5 years. They had been suffering from diabetes for an average of 29.3 years. Four recipients were on dialysis again, whereas two had preterminal renal insufficiency. Pancreas transplants were drained through the bladder (n = 1) or into the small intestine (n = 5) with systemic venous anastomosis. After a median observation period of 28 months (8 to 99 months) all six recipients are insulin free. One patient lost his kidney graft due to severe acute rejection. Therefore kidney graft survival is 83 %. Four acute rejections (66 %) were observed in 4 patients. Only one rejection was treated successfully by steroids. Two rejections could be stopped with antibodies. 3 patients had infections in the early postoperative period (sinusitis, urinary tract infection, wound infection). Even after KTX with graft failure, diabetic patients suffering from renal disease can be re-transplanted successfully with SPK.
