The treatment of patients with diabetes mellitus (DM) presents many challenges to care providers and represents a major proportion of healthcare expenditure worldwide. Successful pancreas transplantation provides durable glycemic control and improves survival for patients with diabetes. Progress in the field has mainly been based on large single center studies and the cumulative analyses of registry data from the United Network for Organ Sharing (UNOS) and the International Pancreas Transplant Registry. This review focuses on the outcomes of pancreas transplantation for patients with and without end stage renal disease. It describes the current state of pancreas transplantation, gaps in knowledge, and future studies needed to enable more patients to benefit from this treatment. A common theme that emerges is the need for multicenter randomized trials in pancreas transplantation to define clearly the efficacy, risks, and long term benefits.
Background. Limited health literacy (HL) is associated with decreased kidney function and death in patients with chronic kidney disease. Less is known about the impact of HL on kidney transplant (KT) outcomes. The aim of this study was to examine the relationship between HL and KT outcomes, including rates of waitlisting, healthcare utilization, acute rejection, renal allograft function, renal allograft failure, and death. Methods. We performed a retrospective review of HL data previously collected at our center. HL was assessed in a convenience sample of consecutive, English-speaking patients age ≥18 y who were evaluated for KT at Mayo Clinic in Minnesota between June 2015 and March 2017 as part of a practice improvement feasibility project (n = 690). HL was assessed using the 4-item Brief Health Literacy Screening Tool modified for the outpatient KT evaluation process. The 4 items assess confidence completing forms, reading comprehension, and oral literacy. Results. Overall, 30.4% of patients had limited or marginal HL. Patients with limited or marginal HL were less likely than those with adequate HL to be waitlisted for KT (hazard ratio = 0.62 and 0.69, respectively), even after adjusting for age, marital status, body mass index, Charlson comorbidity index, or dialysis dependency. Patient HL was not associated with post-KT healthcare utilization, acute rejection, or renal allograft function. Patients with limited or marginal HL appeared to experience a higher risk of renal allograft failure and post-KT death, but the number of events was small, and the relationship was statistically significant only for marginal HL. Conclusions. Inadequate HL is common in KT candidates and independently associated with decreased waitlisting for KT. We observed no statistically significant relationship between HL and posttransplant outcomes in our cohort. Further efforts to improve communication in patients with inadequate HL may improve access to KT.
