522-P: Long-Term Renal Outcomes in Young Onset Type 2 Diabetes

Abstract

Young adult onset type 2 diabetes (YT2DM) is an aggressive disease. Cross-sectional studies have shown a higher prevalence of albuminuria in YT2DM compared to age-matched young adults with T1DM (YT1DM). Whether this translates to poorer long-term renal outcomes has not been widely studied. We aimed (i) to examine progression to renal replacement therapy (RRT) and renal-related death (RRD) in our young adult population, and (ii) to examine survival on RRT for those individuals who reached end stage renal disease. We performed probabilistic linkage of prospectively collected data from the RPA Diabetes Centre eMR to the Australian National Death Index and the Australian and New Zealand Dialysis and Transplant Registry up to 31/12/2015. In our patient cohort diagnosed between the ages of 15 and 35 years, 1,248 had YT1DM and 1,534 had YT2DM. After a median (IQR) observation of 13.6 (6.9-20.7) years, 56 (4.5%) of YT1DM vs. 98 (6.4%) of YT2DM reached the combined renal end-point of RRT/RRD. Analysis of Kaplan-Meier survival curves demonstrated a greater rate of progression of renal disease in YT2DM (Log-rank p=0.003). Cox proportional hazard modelling of RRT/RRD with adjustment for gender, ethnicity and duration of diabetes exposure was undertaken. The HR (95% CI) for an adverse renal outcome in YT2DM relative to YT1DM was 2.0 (1.4-2.9), p Disclosure T. Middleton: Other Relationship; Self; AstraZeneca. S. Chadban: None. L.M. Molyneaux: None.
