Background: Kidney disease is common in patients with heart failure (HF). The Donadio equation combines plasma creatinine and bioimpedance vector analysis (BIVA) to estimate creati-nine clearance. This study aimed to compare the Donadio formula to the Cockcroft-Gault (CG), Modification of Diet in Renal Disease Study (MDRD-4), and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations in patients with HF. Methods: We analysed data from 900 patients (mean age: 76 ± 10 years) with HF. All of them un-derwent clinical, laboratory, BIVA, and echocardiographic evaluations. Results: Donadio equation overestimated eGFR as compared to CG and CKD-EPI formulas (+6.8 and +12 mL/min/1.73 m2, respectively) while computing similar results to MDRD-4 (overestima-tion: +0.1 mL/min/1.73 m2). According to the different formulas, the prevalence of renal insufficiency (eGFR< 30 ml/min/1.73 m2) in relation to the different formulas was as follows: 24% with Donadio, 21% with CG, 13% with MDRD-4, and 23% with CKD-EPI formulas. All the equations demonstrated a high precision rate (r>0.8 for all). There was a “good” agreement between the Donadio and CG/MDRD-4 formulas and “fair” with the CDK-EPI formula. The Donadio equation showed a high accuracy in predicting severe renal dysfunction (eGFR< 30 mL/min/1.73 m2) in patients with HF (AUC > 0.9), showing comparable per-formances to CG. Conclusion: The Donadio formula provided an estimation of GFR comparable to MDRD-4 in HF patients, independently from acute or chronic HF conditions. The use of BIVA in HF patients may be adopted both for HF management and for evaluating kidney function.

Abstract

Background: Kidney disease is common in patients with heart failure (HF). The Donadio equation combines plasma creatinine and bioimpedance vector analysis (BIVA) to estimate creati-nine clearance. This study aimed to compare the Donadio formula to the Cockcroft-Gault (CG), Modification of Diet in Renal Disease Study (MDRD-4), and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations in patients with HF. Methods: We analysed data from 900 patients (mean age: 76 ± 10 years) with HF. All of them un-derwent clinical, laboratory, BIVA, and echocardiographic evaluations. Results: Donadio equation overestimated eGFR as compared to CG and CKD-EPI formulas (+6.8 and +12 mL/min/1.73 m2, respectively) while computing similar results to MDRD-4 (overestima-tion: +0.1 mL/min/1.73 m2). According to the different formulas, the prevalence of renal insufficiency (eGFR< 30 ml/min/1.73 m2) in relation to the different formulas was as follows: 24% with Donadio, 21% with CG, 13% with MDRD-4, and 23% with CKD-EPI formulas. All the equations demonstrated a high precision rate (r>0.8 for all). There was a “good” agreement between the Donadio and CG/MDRD-4 formulas and “fair” with the CDK-EPI formula. The Donadio equation showed a high accuracy in predicting severe renal dysfunction (eGFR< 30 mL/min/1.73 m2) in patients with HF (AUC > 0.9), showing comparable per-formances to CG. Conclusion: The Donadio formula provided an estimation of GFR comparable to MDRD-4 in HF patients, independently from acute or chronic HF conditions. The use of BIVA in HF patients may be adopted both for HF management and for evaluating kidney function.
