Early worsening of diabetic retinopathy after simultaneous pancreas and kidney transplantation-Myth or reality?

Early worsening of diabetic retinopathy due to sudden glucose normalization is a feared complication of pancreas transplantation; however, its rate or severity has not been studied prospectively. We followed up 43 pancreas and kidney recipients for a composite endpoint comprising new need for laser therapy, newly diagnosed proliferation, macular edema, visual acuity worsening, and blindness over 12 months. Although 37% of patients met this primary endpoint, its severity was rather low.

Benefits of Islet Transplantation as an Alternative to Pancreas Transplantation: Retrospective Study of More Than 10 Ten Years of Experience in a Single Center.

Background: Pancreas transplantation (PTx) represents the method of choice in type 1 diabetic patients with conservatively intractable hypoglycemia unawareness syndrome. In 2005, the Institute for Clinical and Experimental Medicine (IKEM) launched a program to investigate the safety potential of islet transplantation (ITx) in comparison to PTx.

Aim: This study aims to compare the results of PTx and ITx regarding severe hypoglycemia elimination, metabolic control, and complication rate.

Hypoglycemia and Glucocorticoid-free Immunosuppression are Related With Low Dehydroepiandrosterone Sulfate Level.

Background: Low dehydroepiandrosterone sulfate (DHEAS) levels and a high cortisol/ DHEAS ratio are associated with higher mortality in elderly, dialyzed, and immunocompromised patients. The role of these hormones in patients with hypoglycemia unawareness (hypo) or in pancreas or islet recipients treated by glucocorticoid-free immunosuppressive regimen (IS) has not been studied.

Objective: The aim of this study was to determine the effects of IS and of recurrent hypoglycemia on DHEAS and adrenocorticotropic hormone (ACTH) levels in patients with type-1 diabetes (T1DM).

[Islet transplantation as a treatment for hypoglycemia unawareness syndrome. Evaluation of the pilot program and comparison with pancreas transplantation].

Islet transplantation (ITx) started in 2005 in IKEM as a potentially safer alternative to pancreas transplantation (PTx), which so far had represented the method of choice in type-1 diabetic patients with conservatively intractable hypoglycemia unawareness syndrome. The aim of the study was to compare these two methods with regard to severe hypoglycemia elimination and to frequency of complications.Up to November 2015 a total number of 48 patients underwent ITx.

Combining Donor Characteristics with Immunohistological Data Improves the Prediction of Islet Isolation Success.

Variability of pancreatic donors may significantly impact the success of islet isolation. The aim of this study was to evaluate donor factors associated with isolation failure and to investigate whether immunohistology could contribute to organ selection. Donor characteristics were evaluated for both successful ( = 61) and failed ( = 98) islet isolations.
