Introduction and methods

Diabetic kidney disease can lead to end-stage kidney disease (ESKD), CVD and premature death [1-4]. Kidney function declines more rapidly in patients with diabetes compared to people without diabetes [5-7]. For the prevention of adverse long-term outcomes, early recognition of diabetic kidney disease progression is necessary.

Meta-analyses have shown that a 30% and 40% decline in eGFR is associated with risks of ESKD mortality in people with and without diabetes [8,9]. However, the percentual decline in these studies was calculated from only two measurements. Thus, the trajectory of eGFR over time was not assessed. The current study aimed to determine the prognostic value of eGFR slope in predicting the risk of clinical outcomes in patients with T2DM.

This study is a post hoc analysis of 8879 participants aged 65.6 ± 6.3 years (mean ± SD) from the large randomized controlled trial ADVANCE and its post-trial follow-up ADVANCE-ON. ADVANCE evaluated the effect of BP-lowering and intensive blood glucose-lowering treatment on vascular outcomes in patients with T2DM. The eGFR slope of each participant was calculated based on three eGFR measurements at 4, 12 and 24 months after randomization (slope ascertainment period). eGFR data of the first 4 months were excluded, because of the acute fall in eGFR known to occur after initiation of RAAS-inhibiting medication.

The primary outcome was the composite of major renal events (chronic dialysis, kidney transplantation, or death from renal disease), major macrovascular events (myocardial infarction, stroke or CV death) and all-cause mortality.

Main results


This post hoc analysis of ADVANCE and ADVANCE-ON data showed that a decrease in eGFR of 3 mL/min/1.73m² per year over 20 months was associated with clinical outcomes in patients with T2DM. This suggests that eGFR slope monitoring over time has the potential to identify T2DM patients at high risk of renal events, vascular events and all-cause mortality.
