Background: Diabetic kidney disease (DKD) is the leading cause of end-stage renal disease (ESRD) in Austria, accounting for a high burden of morbidity and mortality. In this nationwide study, we aimed to evaluate the incidence and fate of patients with DKD-ESRD over time.
Methods: Data (collected annually) from the Austrian Dialysis- and Transplant Registry were analysed for the development of ESRD due to DKD from 1965 to 2013.
Results: Over 48 years, 8322 and 22 975 patients with ESRD due to diabetes and non-diabetes, respectively, entered dialysis. While DKD-ESRD-patients were not dialysed until 1974, in 1975 seven type 1- and one type 2-diabetics started dialysis (1.06 per million population-PMP). In the mid-eighties, DKD-ESRD-patients increasingly were accepted for dialysis (1986: 14.53 PMP, 1996: 31.16 PMP). After a peak incidence of 415 diabetic ESRD-patients in 2006 (50.19 PMP), numbers decreased continuously thereafter (2013: 299 patients, 35.73 PMP). Mean age at start of dialysis increased over time and was lower in type 1- and higher in type 2- compared with non-diabetic patients. Five-year-survival-probability in two diabetic ESRD-cohorts, starting in 2007/08 and 10 years earlier was calculated. Five-year-survival was 28% in 1997/98 and 37.5% in 2007/08. Adjusted relative risk reduction was 33% (HR 0.67, CI 95% 0.57-0.78; P < 0.001).
Conclusion: Despite a growing prevalence of diabetes, the incidence of diabetic ESRD has decreased after 2006. Five-year-survival-probability has improved over 10 years. Multifactorial therapeutic interventions may have resulted in this improvement.
