Abstract

PURPOSE OF REVIEW:

This review will provide evidence that selected patients with type 2 diabetes mellitus (T2DM) may benefit from vascularized pancreas transplantation (PTX).

RECENT FINDINGS:

Initial experience with simultaneous pancreas-kidney transplantation (SPKT) in patients with T2DM and end-stage renal disease (ESRD) suggested that augmentation of endogenous insulin production by PTX in patients with C-peptide-positive, insulin-requiring diabetes resulted in insulin independence, improved glucose counter-regulation, and enhanced quality of life. A number of single-center retrospective studies have documented equivalent outcomes in patients with either type 1 diabetes mellitus (T1DM) or T2DM undergoing predominantly SPKT, although clearly a selection bias exists for patients in the latter category. Selection criteria for SPKT in T2DM include patients less than 55-60 years of age with a BMI less than 30-32 kg/m², insulin-requiring for a minimum of 5 years with a total daily insulin requirement less than 1 u/kg/day, a fasting C-peptide level less than 10 ng/ml, absence of severe vascular disease or tobacco abuse, adequate cardiac function, and presence of 'complicated' diabetes. Data from the International Pancreas Transplant Registry show that up to 7% of SPKT recipients are classified as having T2DM and that outcomes in these patients are comparable to those undergoing SPKT and classified as having T1DM.

SUMMARY:

Consequently, characterization of the 'type' of diabetes may be irrelevant and insulin-requiring diabetic patients with ESRD should be evaluated for PTX based exclusively on their predicted ability to tolerate the surgical procedure and requisite immunosuppression as well as comply with a stringent posttransplant follow-up regimen.
