403-P: Body-Weight Cycling and Risk of Diabetic Kidney Disease in People with Type 1 Diabetes

Introduction 60ml/min/m2) during follow-up occurred in 128 participants (8.9%). A high VIM was significantly associated with occurrence of stage 3 CKD (adjusted HR 1.36 95% CI, 1.12-1.63, p= 0.002), doubling of serum creatinine (1.36 1.15-1.60, p=0.0005), decline in eGFR3ml/min/m2 per year (1.47 1.14-1.89, p=0.003), and “Certain drop in eGFR” KDIGO criterion (1.20 1.02-1.41, p = 0.03), after adjustment for nephropathy risk factors at baseline and throughout follow-up, and use of nephroprotective drugs. VIM was also associated with the incidence of microalbuminuria (1.21 1.08-1.36, p = 0.002) and macroalbuminuria (1.36 1.14-1.61, p= 0.0009), adjusted for baseline covariates, but associations did not remain significant following adjustment for follow-up covariates. Similar results were observed for the other BWV indices. Conclusion: BWV is significantly associated with an increased risk of renal events in people with T1D, regardless BMI and traditional risk factors. Disclosure M. Camoin: None. K. Mohammedi: None. P.
