515-P: Nonalbuminuric Diabetic Kidney Disease in Type 1 Diabetes: Incidence of Major Vascular Outcomes over a 10-Year Follow-Up

Non-albuminuric diabetic kidney disease (Alb-DKD) has been associated with a raised risk of CV outcomes and all-cause mortality in T1D. We report about the association between DKD phenotypes and CV outcomes in a single-centre, prospective, 10.4±2.9 years observation of 774 T1D. Rates of outcomes and vital status were censored on December 2017. Out of 774 T1D, 692 (89.4%) had no-DKD, 53 DKD 1-2 (6.8%), 17 (2.2%) Alb-DKD and 12 (1.6%) Alb+DKD. Incidences of CV outcomes, coronary events and ESRD were available for 736 subjects (95.1%). A CV event occurred in 49 T1D (6.7%; 6.42 events x 1000 PYs), rising from no-DKD (4.2%) to DKD 1-2 (28.6%) and Alb-DKD (35.3%). In Alb+DKD, due to competition with all-cause death, only 1 event occurred. Compared to no-DKD, the adjusted HRs were 4.43 (95%CI 2.27-8.61, p Disclosure M. Garofolo: None. E. Gualdani: None. F.
