Background
Albuminuria and eGFR are biomarkers for kidney disease progression but fail to explain all future risk. Additional biomarkers that better represent underlying disease pathophysiology may improve the prediction of progression from chronic kidney disease (CKD) to end stage renal disease (ESRD). We examined if baseline plasma metabolites predict renal outcomes in the Canagliflozin Cardiovascular Assessment Study (CANVAS) participants.
Methods
Plasma metabolites were assayed from a subset of the CANVAS study participants by HPLC (HILIC)-mass spectrometry using targeted assays. Forty-two metabolites were analyzed for association with the renal outcome (40% eGFR decline, end-stage kidney disease, or renal death) using Cox regression.
Results
We included 967 (22%) of the 4,330 CANVAS participants comprising 341 females (35%), mean age 63 ± 8 years, and BMI 33 ± 5 kg/m2. All patients had T2DM with mean HbA1c 8.2 ± 0.9%, eGFR 75.5 ± 18.3 mL/min/1.73m2, and median ACR (1Q, 3Q) 11.89 (6.5, 37.49). During a median follow-up of 5.6 years, 63 (6.5%) patients experienced a renal event. There were 10 metabolites significantly associated with the renal outcome (all P <0.05) when adjusted for age and gender (Figure) and treatment effect. In a fully adjusted model (age, gender, race, BMI, HbA1c, cholesterol, blood pressure, history of heart failure, baseline ACR and eGFR), arginine alone remained significant (P = 0.01).
Conclusion
Lower baseline plasma arginine levels are independently associated with high risk for renal events in patients with T2DM.
