The timing of dialysis and kidney transplantation in type 1 diabetes

Abstract

Despite significant improvements in the treatment of diabetic nephropathy over the last 20 years, patients with type 1 diabetes are at high risk of developing end-stage renal disease (ESRD) and high mortality once ESRD develops. The timing of dialysis initiation has occurred earlier over the years, but a recent study has led to a re-evaluation of that approach. People with type 1 diabetes treated with pre-dialysis (pre-emptive) transplantation have a lower death rate than people with type 1 diabetes treated with dialysis. Living donor kidney transplantation is possible before starting dialysis and is associated with better kidney and patient outcomes as compared to transplantation while on dialysis. Multiple barriers remain that prevent people with type 1 diabetes from enjoying the reduced risk of death afforded by a pre-emptive kidney transplant, including lack of knowledge by primary care physicians, endocrinologists and nephrologists, late referral for transplantation, patient and family misconceptions about timing of transplantation and who can be a donor. New data on both the optimal time to initiate dialysis or to pursue transplantation will be reviewed.
